Comparison of the types of password safes

The advantages and disadvantages of various types of passwords used in common safes The commonly used passwords in the safe cabinets on the market include mechanical, electronic, swiping, fingerprint and remote password boxes. More is still the front of several types, the following analysis of the different types of passwords their advantages and disadvantages:
1, mechanical password is relatively stable, durable, and does not require power. However, the operating methods are relatively slow, inconvenient, and requiring passwords for professionals.
2. The electronic password has the advantages of quick operation, simple and random change of password. Although the price of electronic code locks has dropped over the past few years, the quality has also improved, but because of its complexity, its stability and durability are inferior to those of mechanical codes.
3, card locks can use their own bank card to open the safe door, but if the IC card requirements and strong magnetic things put a piece, it is not easy to use!
4. Fingerprints are hard to find in the world. Therefore, the fingerprint recognition technology is applied to safes, and the confidentiality is strong and easy to use. However, the opponent's dry humidity requirements are strict! The recognition of the position of the finger is also relatively rigid! Even if it is the same finger, if the position before and after the opening is different, it may recognize the failure!
5, if it is the need for high anti-theft performance safe, the selected safe should not have an emergency key (alternate key) hole, because the emergency key although the location is more hidden, but if the thief is found, only need to pass this emergency key can Open safe directly, with a very large security risk. However, if you choose such a safe, if you really forget the password and miss the key, you can only force it to open by force. The manufacturers who have no emergency key safes include all-insurance safes, Yongfa and Aipu, all of which are high-end products.

How to choose dual-use weight sensor?

The bulkhead is an important instrument for determining the bulk density of grain, and it is used very frequently in food inspection. If you want to separately measure the bulk density of large grains such as corn and small grains of wheat, you need to select two different types of weights, which is very troublesome. Now that the dual-use capacity loader combines them into one, it only requires the use of a single weight sensor to determine the bulk density of corn and wheat, which greatly simplifies the steps of operations and plays an important role in the current food acquisition and circulation. effect.
The dual-purpose weight-receiver uses electronic weighing and measurement. It is also referred to as an electronic capacitance loader or an electronic dual-use weight-receiver. Compared with the conventional mechanical weight-receivers, the main difference between them is the weighing and weighing. The difference is that one is electronic and the other is mechanical. The use of electronic dual-purpose weight-receivers is simpler and more accurate in operation, and the range of use is also wider. Therefore, most of them are dual-use weight sensors.
With the popular use of dual-use weight-receivers, more and more people have seen the important role of dual-use weight-receivers in grain trading and inspection. Therefore, many units need to purchase dual-use weight sensors, and then they must meet their own needs. The situation, how to choose the appropriate dual-use capacity of their own work loader it?
1. Since the dual-use weight sensor can determine the bulk density of corn and wheat, it is not necessary to select the size and model according to the measured substance. This is very convenient for the user.
2. Some dual-purpose load receptors are equipped with a print function, and some are not, and some are optional. Therefore, it is necessary to determine whether or not this function is needed at this time.
3. In the purchase of dual-use weight receptors, choosing a professional seller, such as top cloud farmer, can save a lot of annoying things, such as the first is the quality of the product is guaranteed, and then can provide all aspects of knowing services. In addition, if the instrument fails, the production company also has perfect after-sales service, and can contact and resolve it in time.
In short, the key to purchasing a dual-use weight-based device is whether the dual-use weight-based device purchased meets the needs of their own company or department. The quality of the next product is guaranteed. The last step is to see if the price is appropriate. There are also many users. Focus on the sale of this piece. It is true that many companies now have good product quality, but the problem of incomplete after-sales service. Therefore, when users select dual-use weight sensors, they can also consider it comprehensively. The simplest method is to choose a company such as Top Cloud Yunnong. Scale, technical R&D and after-sales companies are all relatively good to cooperate.

What information can be analyzed by the plant root image monitoring and analysis system?

The contribution of the plant's root system to the plant is self-evident, but at the same time, if the root system grows unhealthy, it will also have a restrictive effect on the plant. Therefore, in order to study the dynamic growth process of the root system and the relationship between the life and death of the root system and its living environment, People began to use the plant root image monitoring and analysis system to monitor and analyze the roots of plants.
Roots are organs that fix plants and absorb water, nutrients, and salinity from the soil. They are both direct users of soil resources and direct victims of stress factors such as acid, alkali, salt, and drought in the soil environment. Therefore, plant root image monitoring is used. The analysis system to study the dynamic characteristics of the plant roots is of great significance for the development of modern agriculture.
The most important technology applied to the plant root image monitoring and analysis system is the image processing technology, which uses the photograph to obtain the root system image information, and then the relevant parameters are determined by the image processing software, thereby realizing the digitization, visibility, informatization, and dynamics of the root research. Non-destructive monitoring purposes.
Plant root image monitoring and analysis system is the most appropriate research method and method for obtaining plant root data. Using it not only has little damage to the root system of plants, but also can monitor the growth status of the root system in real time and accurately estimate the root length and root distribution density. And the dynamic nature of the root. In other words, the root system image monitoring and analysis system can intuitively observe the root system, and obtain some characteristic values ​​and dynamic characteristics of the root.
Plant root image monitoring and analysis system is a new technology method that has emerged in recent years with the increasing maturity of digital technology, feature recognition technology, and image processing technology. Its application solves the problem of large manual workload and poor accuracy in the past. Such drawbacks have enabled the digitized, visualized, informatized, and non-destructive dynamic monitoring of plant roots, not only enriching the knowledge of plant root phenology, but also providing botanists with the necessary experimental means for studying root systems.

Children's playground slides

One, slide

Children playing slides can exercise their children's ability to climb and help stimulate the development of the vestibular system, but their risk is not small. For example, the children under the children's combination slide failed to pass the cushion, resulting in the child's injury, or the child's competition, pushing and falling from a height.

Countermeasures:

Before the children play the children's slides, check whether the cushioned floor mats are of elastic material, whether the thickness is sufficient, whether the installation of the slides is firm, whether the height of the handrails or the guardrails near the chutes is up to the child's waist, and so on.

When parents are playing slides, parents should take care of them. Parents should stand at the bottom of the slide if there is a closed slide with an arch or guardrail design. If it is an open slide, they should stand on both sides of the slide to prevent children from falling from both sides.

Second, the swing

Swing is one of the children's favorite games. In the process of playing, accidents occur. Normally, the children do not follow the conventional rules, but they circling in the same place around the swing chain. It is very likely that they will be strangled by the neck, and they may be injured by metal chains. In addition, the child walks past the swinging swing and may be hit and injured.

Countermeasures:

Before the children play the swing, the parents should firstly reduce the hinge connection of the swing chain, and the small holes of the chain should be less than 0.8 cm in order to prevent the children's hand cards from being damaged. It is best for babies to use plastic or rubber swings, while older children can choose wooden or metal swings.

Parents should teach their children to grasp the ropes tightly with both hands and wait until the swings are completely stopped and come down. When you are playing with a swing, do not stand or squat, but sit. You can't circle the swing rope around your neck and you can't stay around the swing.

Third, seesaw

The seesaw is a game that requires the collaboration of two children. Its accident is usually because a child sitting in a section suddenly runs away from the seesaw, causing the child sitting at the other end to react and drop from above.

Countermeasures:

Select a lower jaw board for your child. Before playing, check whether there are missing parts or corrosion problems. Then hold your baby firmly with both hands, do not try to touch the ground or vent; both feet naturally on both sides, do not curl under the sacral plate. If there is any need to adjust, we must first tell adults.

Fourth, the sand pit

Children like to play with sand and water. If you accidentally raise the sand into your eyes, it will cause harm to your child's eyes. And the hard objects buried in the sandpits can also cause harm to children's hands and feet.

Countermeasures:

Before children play, parents should first check whether there are foreign objects in the sand pit, such as stones, iron wire, nails, roots, broken glass, and so on. Teach children not to throw sand. When other children see throwing sand, they must stop immediately. If your child's eyes come into the sand, or if his or her hands or feet are punctured, clean them immediately and if necessary, go to the hospital. When the child is not playing sand and ready to leave, use a wet tissue to wipe the baby's hands, and tell the children not to rub their eyes with dirty hands.

Radiation recorder provides the basis for grape growing

In general, climate and environment are one of the most important factors affecting the growth of crops and are also closely related to the quality of agricultural products. In order to make the grapes planted in the grape production bases sweeter and larger, the yield is also higher, and the meteorological environment detection instruments such as radiation recorders have begun to be applied to grape growing to provide timely and accurate basis for scientific guidance of agricultural production.

In the past, grapes were cultivated, and the weather conditions were difficult to grasp. Due to climate-related loss of grape crops and product losses, the fruit growers could not grasp the climate in front of nature and could only rely on luck and feelings, which affected the quality of the grapes. And production. The dependence of plants on light is strong. Photosynthesis is an important process for crop nutrient accumulation. Measuring the intensity of photosynthetically active radiation is an important process for studying plant nutrient accumulation. Therefore, using radiation recorders to measure photosynthetically active radiation can help The fruit grower accurately grasps the total radiation and effective radiation in the grape shed, uses it to combine meteorological work and agriculture, develops meteorological services for farmers, seeks advantages and avoids harm, and escorts grape cultivation.
In addition, for the convenience of research, the total light radiation, effective radiation and other data measured by the radiation recorder can also be exported to the digital display platform for further analysis by relevant experts. With these observations, the technicians can be more comprehensive. To understand the climate characteristics within the shed, guide farmers to seek advantages and avoid harm, and improve efficiency.
The application of radiation recorders in modern grape growing is just a microcosm of the current development of science and technology agriculture. With the development of agricultural modernization, the application of radiation recorders and other microclimate monitoring stations in agriculture will become more extensive, and its most important significance. It is based on the real-time information that has been monitored, combined with weather forecasts, and early warning information release platforms such as SMS warnings, electronic display screens, and networks to timely disseminate weather service information to farmers throughout the city to scientifically guide agricultural production.

Analysis: Several Misunderstandings About Customers' Purchase of Safes

Analysis: Several misunderstandings about customers buying safes There are a variety of safes on the market. Brands are like many stars, and their styles have their own characteristics.
How to buy a safe with a relatively high cost performance is a realistic issue that has to be considered by consumers.
I. Mistakes in fire prevention cabinets:
State-certified safes only have CCC-certified safes. Their fireproof cabinets are not classified as safes. They can only be referred to as general high-ranking safes. Relatively safe, these safes are expensive, but they have a high degree of security. Have been reduced, the internal has a special fireproof material, the quality of the import is better than the domestic quality, because the cabinet of the cabinet is relatively thick, so it has a certain anti-theft function, in order to prevent theft, it is recommended that consumers buy a national mandatory certification Although the price of safes is relatively high, the anti-theft factor is relatively good. If anti-valuable items are stored, it is better to import imported fire-proof cabinets.
Second, the model error:
Various types of safes are available. Prices should be compared with safes of the same size. The comparison between different brands is close to the safe, the same product is of good quality, the same quality is the same as the safe, and the safe is also the same. It is recommended that consumers have better insurance of the same size. The price of the cabinet then makes the decision.
Third, the appearance of errors:
Some of the safes in the real market are difficult to identify authenticity from the outside, and they are also electronic locks. The same size, why is the price difference a lot? Because there are a number of counterfeit cabinets posing as safes, the storage cabinets are relatively thin, and the door panels are laminated. From the outside, the thickness and the real safe are almost the same, but after opening the rear cover, it is found that all are empty. The actual plate thickness is less than the thickness of the metal cabinet, and even lost to the metal cabinet, it is recommended that consumers first knock on the safe door when buying the safe to see if it is hollow, the real safe and safe No matter if it is a hand or a sound, it's not the same.

Soil nutrient rapid tester returns soil to fertile soil

In fact, we know that the quality of current agricultural soils is very unsatisfactory. The main reason is that the excessive use of chemical fertilizers in the past destroyed the internal structure of the soil, resulting in soil compaction and reduced soil fertility, making it difficult for crops to increase production and become serious. The problem of agricultural pollution. The dependence of modern agricultural development on the soil is self-evident. Therefore, the current key task is to recognize the seriousness of the soil problem and actively use the soil nutrient rapid tester to carry out the correct fertilization operations and return the soil to thousands of miles. Fertile soil.

Many people's wrong artificial organic fertilizers with high prices are good, but in reality this is not the case. The first is to look at your soil conditions. In the past, it may have been the soil delivery inspection agency to detect your soil physics and chemistry this year. Indicators, but now mostly using soil nutrient rapid tester to determine, and second, according to the results of soil nutrient rapid tester to determine what kind of crop your soil is suitable for planting, and the third is to choose the right according to the actual situation of soil and crops Organic fertilizers are applied according to the demand of the crops. It can be seen that "soil, crops, organic fertilizers" are all adapted, and organic fertilizers can show good fertilizer efficiency. During this period, the soil nutrient rapid tester played a very important role.

In other words, to provide soil quality and the benefits of agricultural planting, scientific fertilization is the most important, that is, to apply fertilizer according to the needs of soil and crops, to avoid the adverse effects of excessive fertilization on agriculture, environment and soil. The basis for this work is to accurately measure the soil test data measured by the Soil Nutrient Rapid Tester. It can be said that the soil nutrient rapid tester is an intuitive and important step for scientific soil management.

After applying the soil nutrient rapid tester, agriculture fertilization has an important know-how. The fertilization operation is completely applied according to the needs of soil and crops, which not only improves the utilization rate of agricultural resources, reduces the production cost, improves the quality of crops, and eases the use of water and soil. Pollution, increased farm income, and continued creation of greater value for the agricultural industry chain ecosystem, realizing the hope of returning China's soil to fertile ground.

How to ensure the adhesive strength of corrugated cardboard

Corrugated board adhesive strength depends mainly on the quality of the adhesive and corrugated board production line sizing quality.

Adhesive quality

The quality of the adhesive depends mainly on the strength of the adhesive manufacturing process and the quality of the raw materials used. The main raw material used for the binder is starch, which generally uses cornstarch above industrial grade one. If starches with lower grades are used, due to their poor processing precision, impurities such as proteins and fats will be consumed, more caustic soda will be consumed, the binder will be unstable, the bonded corrugated cardboard will absorb moisture easily, and the adhesive It is easy to produce gels with larger starch granules and impurities as the core, which deteriorates the fluidity.

Solid content, initial viscosity, viscosity, gelatinization temperature, etc., are important indicators for measuring adhesive quality:

1. Solid content

The solid content of the adhesive should be determined according to the equipment accuracy, operating speed, and the actual condition of the base paper. Once the high-speed wide corrugated board production line reaches a speed of 200 m/min or more, the solid content of the adhesive must be high. Water and starch are required. The ratio is usually between 2.5:1-3:1. The high solid content of the binder, the relative reduction of moisture, the smaller amount of glue can guarantee the adhesion of corrugated board; and the change of the moisture in the corrugated board processing process is small, which can reduce the warpage of the corrugated board. If the precision of the enterprise equipment is low, the speed is slow, the base paper is permeable, and the solid content of the adhesive is lower, otherwise the quality problems such as degumming of the corrugated cardboard, crystallization of the paste line, and popping may occur.

2. Early tack

The initial tack is the key to ensure the adhesion of corrugated cardboard and increase the speed. In the production of corrugated board, the preheating area of ​​the base paper is increased, or the cross-linking agent is added during the production of the adhesive, and borax is added to the main body and the carrier tank to increase the solid content of the binder, and the adhesive can be coated. After a short period of time began to produce adhesion, and its cohesive force can damage the paper fiber.

3. Viscosity

The lower the adhesive viscosity, the better the flowability. The fluidity of the adhesive determines the permeability of the adhesive, the uniformity of the sizing, and the amount of glue, directly affecting the speed of the vehicle, the bonding of the paperboard, the flatness and strength of the paperboard. In addition, the higher the proportion of starch in the binder, the poorer the flowability; the high solid content binder can also maintain a very low viscosity by adjusting the formulation process. Under normal circumstances, when the adhesive is recycled, its viscosity will decrease once it passes through the circulation pump. At this point, it should be blended with the newly produced adhesive.

4. Gelatinization temperature

The gelatinization temperature refers to the initial temperature required to convert the starch binder into a paste. The gelatinization temperature of the binder is a problem in solving the gelatinization temperature of the binder, which is a key factor in maintaining high-speed production, except that the caustic soda is adjusted. Dosage and heating methods, the appropriate addition of some additives can also have the same effect. The gelatinization temperature should not be too low, otherwise it will cause the adhesive to gelatinize during the cycle and affect the fluidity of the adhesive. The gelatinization temperature of the adhesive should be adjusted according to seasonal changes. In the winter, the gelatinization temperature can be adjusted to 55-60°C, and in the summer, the gelatinization temperature can be adjusted to 61°C-66.

Corrugated board production line sizing quality

In Europe and America, the most important one for checking the quality of corrugated boxes is the inspection of the width of the viscose glue line. The standard sizing is precisely positioned, the adhesive is applied evenly and smoothly throughout the peak, the paste lines are clearly outlined, and no adhesive is ejected laterally from the corrugations, leaving no trailing glue marks. [next]

The bad sizing is mainly related to the equipment state, adhesive quality, and quality of the base paper of the corrugated cardboard production line. The common quality problems caused by poor sizing mainly manifest in the following aspects:

1. Dropping glue

There are dirt on the rubber roller, such as paper scraps, agglomerates of starch and other foreign materials, etc., or the foreign material on the roll surface is blocked, causing the gluing roller to fail to squeegee, only a small amount of adhesive can be transferred, and it can be easily wiped. Falling, glue will appear at the peak of the glue on the lack of intermittent gluing phenomenon. The surface of such a corrugated paperboard will show signs of layering of the paper and the core paper, and the compressive strength, side pressure strength and adhesive strength of the carton will be reduced.

When the gap between the upper and lower corrugating rolls is too wide, the upper roll cannot contact the lower corrugating roll and there is not enough adhesive on the corrugation peak.

2. Adhesive lateral ejection phenomenon

Adhesive viscosity is too high; when it is too low or the content of borax is too high, lateral spraying of the adhesive is likely to occur when the production line is running at a high speed, which may cause warpage of the cardboard or softness of the cardboard, adhesion of the carton, side pressure And the compressive strength will be reduced.

3. Guide paw marks or vacuum marks

Traces of guide jaws or vacuum marks appear on the sizing part. The cartons made of such corrugated cardboard often break during use, and the side pressure strength of the corrugated cardboard and the compressive strength of the carton are greatly reduced. Corrugated cardboard produced by a single-faced machine with guide jaws often exhibits leader marks (a clear, adhesive-free space) at the sizing section, usually due to bending, wear, misalignment or adjustment of the guide jaws. Large; the adhesive accumulates on the baffle and condenses into a mass, and these hardened starches will rub off the adhesive on the roller and form a blank trace of the leader. In addition, the high moisture content of the corrugated paper and the abrasion of the wide adhesive on the glue roller caused by the wear on the rubber roller or by the foreign material will cause this quality problem. Non-guided single-sided machines often have vacuum marks on the gluing section. This is mainly due to too much vacuum in the corrugating roll. The vacuum will cause the corrugated base paper to be excessively affixed to the corrugating roll, causing the core paper to dent, and the rubber roll cannot The adhesive is applied to the ridges of the recessed core paper.

4. Severely blurred intermittent sizing

This phenomenon occurs before the glue roller, mainly due to the distance between the guide jaw baffle and the corrugating roller is too large, the guide jaw baffle is damaged or worn, the moisture content of the corrugated base paper is high, the pressure on the pressure roller is not uniform, the corrugating roller There is dirt, the brake on the core paper paper is slack, the pressure on the corrugating roller is uneven or the pressure is too low, there is no vacuum on the corrugating roller or there is no vacuum temporarily.

5. Irregular sizing shapes

The irregular sizing shape is mainly caused by the unevenness of the corrugation caused by inaccurate position when the guide jaw and the core paper pass between the various rollers. The quality of the core paper, dirt on the corrugating roller, rough surface wear, and guide claws Wear, damage, bending, foreign matter on the guide jaws, lack of guide vacuum pressure or vacuum hole plugging, improper pressure on the pressure roller, too much or uneven brake tension on the core paper, etc.

6. Insufficient or no adhesive on adhesive

Adhesive viscosity is too low, jamming of the rubber roller net, and gap between the rubber roller and the rubber roller are too small, which can lead to insufficient sizing. The gap between the rubber roller and the corrugating roller is too large, the steam condensate drips on the gluing roller, the adhesive liquid level in the glue amount is too low, the contact between the lower corrugating roller and the pressure roller is bad, and the height and position of the corrugating roller are not All will lead to no adhesion phenomenon.

7. Adhesive oversizing

Adhesive sizing is usually due to excessive gap between the squeegee and squeegee, or excessive viscosity of the adhesive. Not only does the adhesive waste, but it also results in problems with slatted cardboard or warpage of the board, and in severe cases, significant wrinkling occurs.

8. Effect of corrugating roller on sizing

Corrugated rollers have depressions, dirt on the surface, damaged or worn corrugated rods, non-uniform corrugating roller clamping pressure, corrugating roller corrugation is not parallel and will affect the corrugated forming, directly leading to poor sizing.

9. Poor sizing at the slit edge

Corrugated cardboard longitudinally edged paper and corrugating medium are not bonded, and loose paper occurs. The main reason is that the slitting tool is not sharp, the slitting machine is running at a high speed, the slitting knife overlaps too much, and the slitting edge has a guide. Paw or vacuum marks, non-uniform moisture content at the edge of the tissue, uneven wear on the corrugating roll due to the difference in the paper web, and adhesive agglomeration on the pressure roller or lower corrugating roller.

Digital Printing Paper Features and R&D (II)

Development of digital printing paper

1. Expand the range of substrates

At present, web digital printers can print a variety of substrates such as uncoated paper, coated paper, polyester, transparent paper, labels, and films. The expanded range of substrates will undoubtedly allow users to broaden the scope of their printing business after purchasing digital presses.

In fact, these choices are limited. Digital printers are still cautious about using new materials. The equipment dealers advise users to use some of the products of high-end paper companies, and most printers only use the products of specific paper manufacturers. At present, digital printer manufacturers usually conduct substrate suitability tests before identifying substrates, and wholesalers sell these substrates only after receiving their approval. After the technology in the paper market matures, digital press manufacturers do not need to do these experiments again, which can save costs.

2. Improve the suitability of paper

It is understood that HP 1ndigo E-Print 1000SR format double-sided printing paper quantitative 100 ~ 340g/m2, Xeikon DCP/500D digital press printing paper format for the 50 ~ 110cm, the basis weight of 80-270g/m2 these paper surface It looks the same, but its performance is not the same. HP ndigo. The use of liquid ink, the surface of the paper to meet the liquid ink transfer requirements, otherwise it may cause part of the picture is not printed, or part of the picture is very easy to erase. Therefore, special paper types are required for a specific digital printer.

3. Reduce paper prices

General digital printers have a small amount of paper stocks. In most cases, they place orders or contact with wholesalers according to user needs, and deliver goods the next day; the print volume is not large, and they are generally around 500 prints. Since the cost of paper accounts for only a small part of the entire digital printing cost, users are not particularly concerned with the price of paper, and they value the reliability of the supplier. With the increase in paper usage and the deduction of manufacturers' R&D expenses, the price of digital printing paper is expected to further decrease.

From the printer's point of view, users are now only willing to buy paper from stable digital printing paper suppliers. Therefore, the digital printing paper market is not optimistic. Over the past few years, the digital printing paper market has been growing. As printers always purchase digital printing papers at high prices, wholesalers will become more and more interested in this market and provide more products.

At present, many large paper manufacturers in the world are committed to developing suitable paper for different printing presses, and the new products will be printed on different devices to continuously improve and improve the performance of the paper. The majority of manufacturers of digital printing presses also actively experiment with various substrates to ensure that the models they produce have a good printability for paper. At the same time, they also adjust the operating parameters of the press according to different papers in order to achieve good results. Print quality and work with paper manufacturers to develop new paper projects.

With the development of digital printing presses and digital printing technologies, China’s demand for corresponding substrates will grow even more, and better solutions will be obtained for the printing pressibility of digital presses and substrates, making digital printing possible. The quality is more perfect. For paper manufacturers, we should learn from the advanced experience of foreign countries, increase the research and development of digital printing paper as soon as possible, and gradually occupy a certain share in the market.

The formulation of various agricultural measures depends on real-time collection and rapid monitoring of soil moisture information. Therefore, the application of soil moisture monitoring system has important practical significance in the current agricultural development.

The application of soil moisture monitoring system can be said to bring soil moisture detection in China to a new stage, which is the automatic detection and forecast stage of soil moisture. Compared with the traditional monitoring methods, the soil moisture monitoring system can work automatically in the field or in the absence of people. It realizes the automatic transmission, processing and statistics of public opinion data, and the public opinion monitoring information can be more comprehensive and accurate. Provide drought information and accurately analyze the development situation of drought, carry out forecasting and forecasting work, effectively prevent drought and drought, and reduce various losses caused by drought.

Because of the obvious economic and social benefits that can be brought about by the application of soil moisture monitoring systems, the promotion and application of soil moisture monitoring systems has grown rapidly in recent years. The research and establishment of soil moisture monitoring systems is aimed at establishing efficient agriculture. Great contributions have been made. At the same time, it has provided reliable technical support for agricultural modernization. At the same time, there are also some problems in the process of promotion, which mainly focus on several aspects.

1. The Internet of things technology adopted by the soil moisture monitoring system requires the support of the network for the transmission of information. However, due to the restrictions of the application areas, the network construction of monitoring stations in some regions cannot keep up, and the system function cannot be fully realized.

2. Because the application of soil moisture monitoring system in agriculture is just in its infancy, it is still in the stage of exploration. Some aspects are not yet perfect, such as the lagging of communication means of intelligence information and the inconsistency of standards.

3. In general, the objective of the soil moisture monitoring system is to quickly and accurately determine the soil moisture in farmland, and to ascertain the profit and loss of soil moisture during the growth and development of crops, so that timely decisions can be made on irrigation, fertilization, or drainage measures. However, due to less systematic integration of soil moisture monitoring systems and flood control and drought resistance decision support systems, it is difficult to achieve seamless connection between systems.

BAIDU_CLB_fillSlot("858283");

Every innovation in library service and management model is based on the application of a new technology. With the progress of the times and the development of technology, the development course of the library circulation management model is shown in Figure 1. The application of computer and network technology liberated the library management personnel from the pure manual management mode and gradually transitioned to computer management. The adoption of magnetic stripe and bar code technology will increase the library from a closed-end management mode to an open management mode, so that readers can swim freely in the book world and pick and choose their favorite books. The pace of innovation will never stop. Librarians are also paying close attention to the development of new technologies and capturing new technologies for libraries. The continuous development, maturity, and industrialization of RFID technology have also received keen attention from the people in the library community and have gradually begun to promote and apply this technology in the field of libraries.

Figure 1 Development history of library circulation management model

Application of UHF RFID Technology in Libraries

In foreign countries, UHF RFID technology has been applied to the field of libraries in countries such as Australia, Singapore and the Netherlands; there are also many libraries in the country that have applied UHF RFID technology, such as Shantou University Library, Beijing Petrochemical College Library, Hubei Yichang Library, etc. There are still some libraries currently planning to implement UHF RFID library management systems.

Key to UHF RFID Technology in Library Applications

UHF RFID technology is applied in libraries. The key technologies that need to be solved include UHF RFID tags , special readers, dedicated antennas, software interfaces, system integration, application software, and application innovation.

(1) UHF RFID tags

1 Book UHF RFID tag (as shown in Figure 2). The book UHF RFID tag is the most basic technology for realizing book information collection, and its performance will directly affect the application effect. The technical performance of UHF RFID tags in books is mainly reflected in reading and writing multiple tags, adapting to different antenna reading and writing capabilities, installation methods, and resistance to damage.

Figure 2 UHF RFID tags for books

There are tens of thousands of books in the library, and as many as hundreds of thousands or even millions of books. The application of UHF RFID tags in libraries is a large-scale "massive" application. Operation requires RFID tags to have good multi-tag read/write performance.

The library management system is an interconnected system. The equipment used is various. There are UHF RFID tag conversion, self-service borrowing, inventory, security access control, and automatic sorting. Each device reads and writes RFID tags. The requirements are not the same, which requires the UHF RFID tags of the books to be suitable for the reading and writing requirements of all devices. Otherwise, the collection of books and information will cause problems at certain stages and affect the application results.

The application of UHF RFID tags for books is also worthy of attention. Reasonable methods of adhering can shorten the time for UHF RFID tags to be sold, and quickly deploy UHF RFID applications. The UHF RFID tag's ability to resist damage is related to the tag itself and closely related to the way it is applied. The UHF RFID tag of the book is attached to the cover page of the book (inside the back cover) and to the spine of the inner page. The effect of anti-corruption is very different.

2 CD-ROM UHF RFID tags (as shown in Figure 3). Optical UHF RFID tags are special labels for audio-visual disc data. Their main technical characteristics are reflected in the recognition distance, multi-tag read performance, etc. At the same time, the installation of the UHF RFID tags on discs cannot affect the normal reading of the disc itself. take.

Users can choose the appropriate color according to the specific environment.
Second, place the placement is also very important, hidden and harmonious is the main principle. Generally placed in the cabinet (this type of safe maximum size does not exceed 50CM, the weight does not exceed 30 kg) corner \ large table under the mobile cabinet \ wall embedded. Home users choose to be placed in bedside cabinets or wall recesses. The wall can be embedded with bolts, while the cabinet type is often secured with forest screws or plastic expansion screws.
Third, the size of the safe is generally available in size 25-168CM, to meet the needs of different sizes. Home users have more choices for smaller sizes, especially for wall-embedded ones. It is recommended that you first consider the placement point, measure the size of the space, and then select the appropriate size and size of the safe.
Fourth, the shape of the current safe has a flat, streamlined, inclined three types of optional. The flat type is firm and steady; the streamlined lines are soft, giving a cute naughty visual experience; the beveled shape is new, and you do not need to bend over when entering the password. If conditions allow, manufacturers can be designed as a model of bed freezer, matching directly with furniture. Or the embedded security box style can be embedded in furniture or embedded in a wall.
If it is an in-line safe and the color cannot be kept in line with the wall or the furniture, the decorative painting can be used outside the safe and it is beautiful and can hide the safe.

Medical students can use VR technology to simulate human anatomy

Students can remove each layer of skin from the skin, from the skin to the deepest bones. The virtual reality interface allows them to better understand the interactions between muscles, organs, nerves and blood vessels.

For centuries, the main method used by medical students or novice doctors to understand the structure of the human body has still been achieved by dissecting the body, and there has been no major change. But now students at the University of California, San Francisco Medical School can use virtual reality as a training method in their first year of study. They can use technology to learn ahead of time before they formally contact the human body.

Anatomy knowledge is the foundation of all medical knowledge, and virtual reality technology allows medical students to more fully understand the complex structure of our body.

Anatomy Derek Harmon, an assistant professor of anatomy, said that virtual reality technology is a good complement to existing courses. He said: "Virtual reality is an exciting learning style for us because it helps to enhance students' understanding of the body's structure. For doctors, the more they understand the human body, the future career development will be. The better it will be."

Although textbooks and practical physical anatomy training are very useful processes, virtual reality teaching allows students to understand knowledge through a new dimension. Students can remove each layer of skin from the skin, from the skin to the deepest bones. The virtual reality interface allows them to better understand the interactions between muscles, organs, nerves and blood vessels. Harmon said: "This is a learning experience that puts all the problems together and focuses on solving them."

Virtual Reality Simulation Learning is part of the Bridges Curriculum program at the University of California, San Francisco School of Medicine. It is an innovative attempt to teach students how to see the nature of health care interconnections.

Surgeons can already perform operations in surgery through virtual reality techniques. Even before someone enters the operating room, they can practice each step in the virtual reality world.

Kimberly Topp, professor of physiotherapy and anatomy at the University of California, says virtual reality technology can simulate real-world medical experiences, such as what doctors may encounter in the emergency room. “Without injuries, it is difficult to simulate real-life experiences, and this is a good way to get students to simulate in advance into the actual clinical environment,” said Professor Kimberly Topp.

“People are full of imagination about how to use virtual reality technology, and this is also a new way I think it can help students remember complex anatomy knowledge,” she added.

On the other hand, for those friends who are not medical students, it is also possible to simulate the surgery of surgeons by bringing equipment such as the Oculus Rift.
