Design of rice intelligent water-saving irrigation system based on agricultural internet of things

In order to realize the real-time remote monitoring and accurate management of the paddy field environment, the intelligent water-saving irrigation system based on the agricultural Internet of things was designed. The data packet consists of water level, soil moisture, soil fertilizer, crop height, real scene photos and so on, which are collected by the terminal monitoring equipment group, and is forwarded to the gateway through the main controller. The gateway transmits the processed data packets to the cloud server through GPRS, and then sends to the user app or the Internet web page. App and the internet can set the upper and lower threshold of the terminal node water level. According to the comparison results between the water level and the threshold set by the water level sensor, the node solenoid valve is controlled to open or close the gate of the rice field intake, and the automatic irrigation is realized. The system can set a fixed number for each monitoring node to find fault units quickly and enhance system reliability. The system gets the advantages of simple implementation, low power consumption, perfect function, and high reliability.
