为了提高水资源利用率以及灌溉的智能化水平，设计了一个应用于喷灌环境下的节水灌溉控制系统。系统主要由STM32最小系统、温湿度检测模块、WIFI模块、辅助电源模块以及灌溉控制模块组成。通过物联网云平台实现了主控制器与手机APP进行数据交换，同时设计并实现了一款基于Android平台的手机APP，增强了人机交互友好性。采用MATLAB的simulink工具实现了以黄瓜初花期为例的模糊控制算法仿真，将湿度以及湿度误差值作为输入量，控制灌溉时间，达到喷灌模式下节水灌溉的目的。通过仿真以及相应实验证明该系统可以实现自动及手动两种灌溉模式，节省人力操作方便，具有一定的推广性。
In order to improve the utilization rate of water resources and the intelligent level of irrigation, a water-saving irrigation control system applied in sprinkler irrigation environment was designed. The system is mainly composed of STM32 minimum system, temperature and humidity detection module, WIFI module, auxiliary power module and irrigation control module. Through the Internet of Things cloud platform, the main controller and the mobile APP are exchanged data. At the same time, a mobile phone APP based on the Android platform is designed and implemented, which enhances the human-computer interaction friendliness. Using the simulink tool of MATLAB, the simulation of fuzzy control algorithm based on the initial flowering period of cucumber was realized. The humidity and humidity error values were used as input to control the irrigation time and achieve the purpose of water-saving irrigation under sprinkler irrigation mode. Through simulation and corresponding experiments, the system can realize both automatic and manual irrigation modes, save manpower and convenient operation, and has certain promotion.
