Design of Food Situation Monitoring System Based on ZigBee and WinCC

In order to solve the problems of limited wiring, high power consumption and limited monitoring information in the traditional grain situation monitoring system, a wireless network monitoring system based on ZigBee was designed, which is composed of sensor module, ZigBee network module and control display module. The main function of sensor module is to collect temperature and humidity information of granary. The ZigBee network module mainly uploads the data collected by the sensor module to the upper computer human-machine interface system for processing, and realizes the remote monitoring of grain situation. The experiment shows that the system is simple in wiring, good in real-time, convenient and fast in data management, and can realize remote wireless monitoring of grain situation.
