Design of automatic irrigation control system based on wireless sensor

In order to improve the stability of automatic irrigation control,reduce data acquisition time and reduce energy consumption,a water conservancy automatic irrigation control system based on wireless sensor is proposed.The software design includes sensor information acquisition module,automatic control information processing module,ad information conversion module,human-computer interaction module and interface module.Using aplc21160 logic control processor as the main control chip,the program control of water conservancy automatic irrigation control system is carried out,and the cross compiler module is designed to load the water conservancy automatic irrigation control instructions.The wireless sensor is used to sample the data of automatic irrigation control system,and the automatic regulation of water flow in the process of automatic irrigation control is carried out by switching frequency conversion method.The algorithm optimization design of water conservancy automatic irrigation control is combined with fuzzy PID control method.In the hardware design part,the control instructions of automatic irrigation control system are sent by DSP,and the control bus design of water conservancy automatic irrigation is carried out by using VIX bus processing technology,so as to realize the hardware optimization design of water conservancy automatic irrigation control system.The system test results show that the output stability of the system is good,the reliability of the system is high,and it has the characteristics of low energy consumption and short time consumption.
