Temperature monitoring system based on industrial Ethernet ring network and ZigBee

The utility model discloses a coal mine temperature monitoring system based on an industrial Ethernet ring network and ZigBee. The system adopts a star-shaped structure, comprises a ZigBee coordinator node and a temperature acquisition node, the temperature acquisition node uses a temperature sensor to acquire temperature information, the temperature information is processed through a microcontroller and is sent to the ZigBee coordinator node through a radio frequency antenna, the coordinator node sends the received information to an industrial Ethernet gateway through serial port communication, and uploads the information to a server through the industrial Ethernet ring network, and display temperature information to a user through ground control center. The coal mine temperature monitoring system in the utility model adopts signal transmission technology which combines the industrial Ethernet ring network with the ZigBee, is convenient to arrange, and easy to use and maintain, and can realize monitoring of temperature values at any points in the underground coal mine.
