The wireless public opinion monitoring system is also called the wireless public opinion and drought management system. It can measure the soil moisture content and record the instruments of soil moisture in stages. In general, we know that if we need to transfer the data measured by the soil moisture analyzer to the computer, we need to use data lines, but our wireless public opinion monitoring system can do wireless transmission without the need of data lines. Complete the rapid transfer of data. The wireless public opinion monitoring system uses a data collector to collect soil moisture information, and can also directly access the computer to collect data. 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 fixed point public opinion monitoring system, wireless public opinion monitoring system has the greatest advantage of being able to achieve wireless data transmission. The wireless public opinion monitoring system divides the test field into 8 areas, A, B, C, D, E, F, G, H, and then uses the center position of each area as a monitoring point, according to the soil moisture monitoring specification SL000-2005 installation. Soil moisture sensor can use sloping multi-point method, according to demand distribution. The GPRS soil moisture monitoring system can be viewed off-line. It can simultaneously detect the multi-point measurement situation in real time and display the measured data in the form of numerical values, curves, and histograms. The wireless public opinion monitoring system has several main components: acquisition terminal, power supply, transmission module, and sensor. 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 monitoring system can use GSM, GPRS, radio station, cable and other methods to communicate. Among them, GSM, GPRS, and radio stations can implement data wireless. Receive and send. GSM and GPRS are the second-generation wireless communication technologies in the world. They can realize the over-the-air data transmission. The soil moisture monitoring system realizes wireless data transmission without limitation of time and space, which greatly improves the transmission efficiency.
