The Wireless Public Opinion and Drought Management System, also known as the Wireless Public Opinion Monitoring System, is capable of measuring soil moisture and recording soil moisture instruments. The wireless public opinion monitoring system uses the data collector to collect the soil moisture information, and can also directly connect to the computer to collect data. Its greatest advantage is that it can realize the wireless transmission of data. Usually, the soil moisture analyzer needs to use the data line for transmission. The drought management system does not require data lines and can directly complete the rapid data transmission. The wireless public opinion monitoring system is applicable to the latest public opinion monitoring specification SL000-2005, and can be configured flexibly according to user requirements. A single system can implement vertical six-point simultaneous detection for up to 60 monitoring points. Has been widely used in agriculture, forestry, environmental protection, water conservancy and other departments, for remote monitoring and monitoring of soil moisture content, water-saving irrigation, greenhouse control, precision agriculture, soil or soil can be carried out on various types of soil indoor or field monitoring. Accurately measure the volumetric moisture content of the soil.
Compared with the sentinel monitoring system, wireless public opinion and drought management system, the biggest advantage is the wireless transmission of data. The Wireless Public Opinion and Drought Management System divides the experimental field into 8 regions, A, B, C, D, E, F, G, and H, and then uses the center position of each region as a monitoring point, according to the soil moisture monitoring specification SL000- 2005 installed soil moisture sensor, can use sloping multi-point method, according to demand distribution. The Wireless Public Opinion and Drought Management System can be viewed offline. It can simultaneously detect the multi-point measurement situation in real time, and can display the measured data in the form of numerical values, curves, and histograms. There are several major components of the Wireless Public Opinion and Drought Management System: Acquisition Terminals, Power Supplies, Transmission Modules, and Sensors. The acquisition terminal is the core operation module responsible for instruction execution and data acquisition. The power supply can have two power modes: solar power and switching power supply. The transmission module is also a key component for realizing GPRS wireless transmission. The wireless public opinion and drought management system can use GSM, GPRS, radio station, cable and other methods to communicate. Among them, GSM, GPRS, and radio stations can implement data. Wireless reception and transmission.
