Soil moisture and drought management systems are commonly used in large-scale farmland operations management, such as the Northeast China region, the southwestern agricultural region, Xinjiang agricultural region and other agricultural areas to achieve the level of mechanization, is a monitoring of soil moisture in the drought The entire system. The system can fully ensure that changes in soil moisture are under artificial monitoring. If there is water shortage or lack of crops, we can take timely measures to carry out farmland irrigation to ensure that the soil moisture content is maintained in a more appropriate range. The soil moisture and drought management system is also called the wireless moisture and drought management system because the instrument contains a GSM/GPRS configuration that enables wireless data transmission. The soil moisture and drought management system is different from the multifunctional soil moisture recorder. The reason is that the soil properties in the same area are different. For example, red soil, etc., should select some soils regardless of the nature when testing. No error detection method will occur, and data transmission will be ensured. Only when the measured data can be transmitted accurately and in real time, can the accuracy and timeliness of the measurement result be ensured. This time the traditional drying method has been used. Far from meeting this goal, it should be done using a professional soil moisture and drought management system.
The system hardware of the soil moisture and drought management system includes: sensors, collectors, peripherals, etc. The specific functions are as follows: Sensors: The soil moisture and drought management system measures the method in line with the "Soil moisture monitoring standards SL000-2005 People's Republic of China water conservancy industry standards Time Domain Reflectometry (TDR) technology can achieve precise, reliable, durable and non-radioactive sources of pollution. In addition, the soil moisture and drought management system can not only determine soil moisture, the most critical parameter of soil, but also measure soil water potential and temperature. And conductivity, is a versatile soil moisture monitoring system. Collector: The collector is the core of the automatic soil moisture measurement system. Its main function is to complete the sampling of soil moisture sensors in each layer, to perform control operations on the sample data, data calculation and processing, data quality control, data record storage, and data communication and transmission. The soil moisture is collected by the collector and recorded inside the instrument. The collector can also set the collection interval and choose freely within 10 seconds to 30 days. When the setting is completed, if it is set to 1 minute, the soil moisture and drought monitoring system will collect soil moisture data once every minute. Finally, the data set of soil moisture changes over time is obtained. Peripherals have power, data transfer, and other modules. Among them, the power supply includes the Xu electromagnetic general-purpose AC and DC battery and the solar energy conversion battery, which broadens the field of measurement. The transmission module includes a variety of transmission methods, mainly including: using GSM, GPRS, radio station, wired, etc. to realize the data transmission and reception. During the data transmission process, the user can select according to his own field conditions.
After the measurement and transmission of data in the above hardware system, the data analysis software of the soil moisture and drought management system is also as powerful. It can process the measured data in various ways and facilitate the process of data changes. View and analyze.
