Abstract:

Abstract: In view of the current mine gas monitoring wiring complexity, communication difficulties and other drawbacks ,the underground gas monitoring system is designed based on the IOT technology . The core of the system is STM32 processor, the terminal detects child nodes is made of the gas sensor 、 the temperature and humidity sensor SHT11 and Zigbee wireless communication module, through routing nodes realize wireless data transmission. Field test data is transmitted in real time to the monitoring center using GPRS technology, Software platform is built with NI Labview, to achieve real-time monitoring of the underground environment and alarms. Test results show that the system is stable, low power consumption, accurate measurement, flexible distribution network.

Key words: gas detection, networking technology, STM32, GPRS technology
