Design of intelligent irrigation system based on single
Abstract: In recent years, with the rapid development of our country, the problem of water supply is more and more prominent, the use of water in agricultural irrigation is huge, and the current situation in farmland irrigation in our country, the amount of water irrigation is still dependent on the common accumulation of irrigation experience, this irrigation model is prone to cause a serious waste of water resources, so we must use water-saving intelligent irrigation technology in agricultural irrigation and save water resources. Improve the efficiency of farmland irrigation water use.
In order to solve the problem of large irrigation water consumption and low utilization rate, a set of intelligent crop irrigation system was designed to achieve intelligent water-saving irrigation. The system is mainly divided into two parts: upper computer and lower computer. In the lower computer, STM32 is used as the main control chip, and the soil moisture in 4 areas is monitored in real time through 4 soil moisture detection modules, and transmitted to the controller. The controller analyzes and processes the soil moisture information collected by the sensor, and then controls the switch of the water pump. At the same time, the field controller is connected to the mobile phone and the remote monitoring platform through the Bluetooth module for data communication, real-time transmission and display of soil moisture information and irrigation information on the remote monitoring platform and mobile phone, while the remote monitoring platform and mobile phone can also send irrigation instructions to the controller. The irrigation time is set through the touch screen of the mobile phone or the upper computer. When the irrigation system receives the irrigation data, it carries out regular irrigation, and can also automatically irrigate according to soil moisture, so as to achieve the purpose of scientific irrigation, precise irrigation and intelligent water-saving irrigation.
Through tests and experiments, the system is easy to operate and reliable, and can effectively improve the utilization rate of water resources to achieve the effect of intelligent irrigation.
