China is a big country in agriculture, and agriculture has gradually entered the production and use of computer-related technologies in modern times. It is necessary to forecast and guide agricultural production. In recent years, drought has severely limited the development of China's economy and has had a huge impact on agricultural irrigation. This has led us to consider how the long-term issue is how to improve the efficiency of irrigation water use. Soil moisture is an important part of the cultivation and growth of crops. The establishment of a soil moisture and drought management system is of great significance for the improvement of the use of irrigation water.
The data transmission module of the soil moisture and drought management system adopts a data transmission method combining a zigbee network and a GPRS network. It overcomes the complexity of wiring and restrictions on the area in wired transmission. Combining zigbee technology for short-distance networking and GPRS technology for long-distance data transmission, the system performance is more superior, the price is lower, and it is easier to promote in reality.
The data acquisition module uses sensors to collect soil moisture data such as soil temperature and humidity, and the GPS device collects data such as longitude and latitude of the monitoring points. The soil moisture and drought management system realizes mutual transmission of data in a single monitoring area through the zigbee network. Using GPRS technology, long-distance transmission of data between zigbee networks and zigbee networks and intelligent terminals is realized. In the smart terminal, the browser is used in combination with GIS technology to display data in different forms to users. The back-end database is used to process, store, and analyze data, query, and statistics.
In the cultivation of farmland soil moisture is commonly referred to as an important parameter in the process of crop growth relative to soil moisture. Soil moisture is constantly changing, so real-time monitoring of the soil moisture and drought management system is required, and the system has a certain value in the collection of information. The change of soil moisture is not only related to the soil properties, but also affected by precipitation, irrigation, evaporation, and the underlying boundary water and its dynamic changes are also a complex systemic problem.
