With the continuous improvement of the technology of wireless sensor of the Internet of Things, it has been widely used. It is mainly used in the fields of petrochemical industry, power industry, industrial manufacturing, medicine, agriculture, farming and municipal administration, which not only improves the working efficiency but also reduces the production cost. Here, Xiaobian combined with the actual needs of users inventory of the Internet of things ten wireless sensor technology typical examples.
First, EMS energy data wireless monitoring
For the United States and the Group of a plant, the following seven branch (assembly a branch, assembly two branch, assembly three branch, light commercial branch, injection branch, electronics branch, the Department of equipment factory) monitoring and Information Analysis.
1, realizes the real-time data acquisition and the monitoring to various power plants on-line energy meter, various flowmeters (such as compressed air flow, petroleum gas flow, oxygen flow, nitrogen flow, etc.)
2, to achieve the power plant of the various lines of electricity, with the amount of compressed air, with the amount of petroleum gas, with nitrogen, with oxygen calculation, statistics, analysis
3, to achieve statistical reporting, real-time data and status display, history and real-time curve functions, remote control, management, redundancy
4, Requires the system has a good open, you can exchange data with other information systems
Second, the underground pipe trench water level monitoring
In order to ensure the safe operation of Shanghai Disneyland throughout the park, scientific and thoughtful monitoring and management of the water supply and drainage network are needed.
1, a total of six points need to monitor the underground pipe ditch water level.
2, when the water level is exceeded, the signal is uploaded to the computer or mobile phone.
Third, power plant pipe network pressure, flow, temperature wireless monitoring
Guangdong Luoding power plant pipe network pressure, flow, temperature wireless monitoring mainly monitors the pipe network pressure, flow, temperature, and valve opening and so on parameters, and when needed, the valve on and off operation. The system consists of monitoring center, communication network, measurement and control terminals and other components.
The data acquisition terminal of each pipe network monitoring point can monitor and collect parameters such as temperature, pressure, flow rate and the like, and also has the remote control function, which can perform the switch regulation and display of the pipe network valve. Data stored in the database for control center and the relevant departments to analyze and decision-making access, and can save at least two years or more, improve work efficiency.
Fourth, intelligent monitoring of agricultural greenhouses
Shenzhen Tsinghua Research Institute of agricultural greenhouses intelligent environmental monitoring needs:
1,4 greenhouse, each monitoring two air temperature and humidity, two soil temperature and humidity, all the way to the concentration of carbon dioxide, all the way to light intensity
2, displayed in three places: touch screen (remote monitoring PC, it is recommended to use wireless transmission); LED screen display related monitoring data from the host about 10 meters
3, PC monitoring PC installation software, display monitoring data interface
Fifth, livestock and poultry farming environment wireless monitoring
Weifang chicken farm in Shandong environmental wireless real-time monitoring, according to chicken breeding farms and different growth stages, monitoring each house temperature and humidity, oxygen, ammonia, hydrogen sulfide, carbon dioxide concentration, light intensity, water consumption, electricity consumption, etc. data.
Real-time collection of on-site sensing signals, remote monitoring of chicken coop running, monitoring background data acquisition, analysis, early warning and alarm, the formation of historical data database to generate historical curves and data reports.
Six, laboratory temperature, humidity, pressure monitoring in real time
Huada gene laboratory temperature, humidity, pressure monitoring real-time needs:
1. On the laboratory environment temperature, humidity, pressure monitoring in real time, at the same time the monitoring data transmission to the monitoring center;
2. The laboratory freezer temperature through real-time monitoring, the monitoring data transmitted to the monitoring center wirelessly;
3. Field collection devices and detection devices using wireless data transmission, wiring is simple, easy to install;
4. Set the upper and lower limits of temperature and humidity sound and light alarm, monitoring software interface directly display, without adding hardware alarms, on the actual screen, respectively, on the temperature, temperature and humidity, pressure drop point for sound and light alarm indication, and sent by SMS cat Alarm information to the designated personnel phone;
5. Equipment output standard Modbus protocol and TCP / IP interface;
6. Can be seamlessly connected with the company's internal network, access to monitoring data through the WEB page, as well as external network remote monitoring server data, remote monitoring of laboratory monitoring parameters anytime, anywhere;
7. Historical data storage, report printing, data graph and so on.
Seven, inverter running status monitoring
Ningbo Libin Technology inverter running status monitoring needs:
a, through the wireless transmission, monitoring the inverter (with RS-485 interface) operating status, displayed in the PC interface
b, control the start and stop of the frequency converter, timing the running time
c, view the inverter input and output
