基于单片机的智能灌溉系统设计
摘 要:近年来，我国发展迅速，供水问题愈加突出，农业灌溉用水量巨大，而且目前在我国农田灌溉中，灌水量多少还是取决于平常积累的灌溉经验，这种灌溉模式容易造成水资源严重浪费，因此在农业灌溉领域必须要运用节水智能灌溉技术，节约水资源，提升农田灌溉用水利用效率。
为了解决灌溉耗水量大、利用率低的问题，设计了一套农作物智能灌溉系统，达到智能节水灌溉目的。该系统主要分为上位机和下位机两部分。在下位机中，以STM32为主控芯片，通过4个土壤湿度检测模块分别实时监测4个区域的土壤湿度，并传输到控制器，控制器对传感器采集的土壤湿度信息进行分析处理，进而控制水泵的开关。同时，通过蓝牙模块将现场控制器与手机端和远程监控平台连接起来，进行数据通信，实时传输并在远程监控平台和手机显示土壤湿度信息和灌溉信息，同时远程监控平台和手机也可以给控制器发送灌溉指令。通过手机触摸屏或上位机输入进行灌溉时间的设置，当灌溉系统接收到灌水数据，进行定时灌溉，还可以根据土壤墒情自动灌溉，从而达到科学灌溉、精准灌溉、智能节水灌溉的目的。
通过测试与实验，该系统操作方便，运行可靠，能够有效提高水资源利用率达到智能灌溉效果。

Design of intelligent irrigation system based on single
chip microcomputer
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.
