Application of Wireless Sensor Network and Chaotic Optimization Algorithm in Intelligent Agricultural Irrigation System

Research on intelligent agricultural irrigation system uses wireless sensor network. A wireless sensor network with Zigbee as the core was designed to monitor and intelligently control different types of soil moisture. In this paper, STC89C52 is used as the core of the microcontroller, and the data measured by several soil moisture sensors are used as feedback information to determine the appropriate humidity parameter interval according to the requirements of crops on water content. We need to compare and adjust the measurement results of the soil moisture sensor and form a voltage signal to achieve speed control of the pump motor. The automatic adjustment of the pump is realized by running the pump motor on the driving circuit of the pump. The chaotic optimization method was applied to optimize the crop irrigation scheme. At the same time, the non-repetition and ergodic characteristics of iteration are used to overcome the local extreme value problem effectively. An example shows that the algorithm is simple in principle, simple in calculation and accurate in result. The agricultural intelligent irrigation system has excellent performance and is convenient to use.
