Agricultural Internet information on the Internet of things the core and foundation of establishing digital management in agriculture, the extension and expansion of the Internet based on the information transmission; It extended and expanded into any goods and goods between, exchange of information and communication, namely material phase. Through radio frequency identification (RFID), infrared sensors, global positioning system (GPS), such as the laser scanner information sensing equipment, as agreed in the agreement put anything connected to the Internet, information exchange and communication, in order to realize intelligent identification, location, tracking and monitoring and management of a network concept.
As people increasingly high demand for agricultural products, the Internet of things in agriculture is becoming more and more widely, the application scope of agricultural production on the key technology of Internet of things is a big help, most areas in China are depend on the soil cultivation, crop growth is good or not has direct contact with soil. Basic needs first suddenly how much water the crops. Primary issue online constantly monitor soil water content, using the current soil moisture sensor is the most popular in the international field test principle of soil moisture: frequency domain reflection principle (FDR), this technology was first applied in the United States, namely sensor launch a certain frequency electromagnetic wave, electromagnetic wave transmission along the probe, arrived at the bottom of the back, detection sensor output voltage, due to the change of the soil dielectric constant usually depends on the soil moisture content, the output voltage and the relationship between the moisture of soil water content can be calculated. The main factors of water is to determine the soil dielectric constant. Measuring the dielectric constant of the soil, which can directly steady response of various soil moisture content. FDR soil moisture sensor to measure soil moisture volume percent, has nothing to do with the mechanism of the soil itself, this principle is the most popular in the international soil moisture sensor measurement method.
Intelligent monitoring system of soil
Remote viewing at any time and place of crop growth, the gardening equipment running status, the production situation, with the "farmers gas flux" mobile phone client, managers can easily remote monitoring, management, production, greatly reduce the workload. Of course, this also provide picture basis for later agricultural products traceability.
Mobile phone remote control is another convenient agricultural content of networked control system control mode, through the mobile client, can remotely check facilities environment data and equipment operation, also can analyze the data, convenient and flexible management.
The valve automatic control function
Based on farmland soil, microclimate and the real-time monitoring of crop growth information. According to the information collected, the combination of crop water requirements and field management of open water pump automatically, realize nobody duty automatic irrigation, subdivision control, prevention of man-made wrong operation.
