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.

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.
