Abstract

For the real-time, on-site, direct monitoring of coalfield fire area temperature, we developed a permanent WSN monitoring system with the functions of continuous collection, high temperature detection, remote control, etc. By designing the software and hardware of SPI interface between the JN5139 chip and the MAX31855 with K type thermocouple, we developed a new type of high temperature sensor node, which temperature range extended to " " " 40" " ~ 1300" " from standard WSN node temperature range. This node can be placed directly on the underground burned area roadway for on-site monitoring. The solar power supply device with protective circuit and low power consumption peripheral circuit provide the data acquisition network with a sustainable energy for all-weather and real-time monitoring. In the uplink data transmission through mobile communication network and Internet to the monitoring center, the heartbeat packets mechanism without manual intervention was used to automatic reconnection, which keeps the link unobstructed to realize the remote control monitoring. The monitoring system that deployed in 12 fire areas of Xinjiang has worked for 45 mouths, and that means technical measures used can guarantee the long-term stability operation of the monitoring system without maintenance. Urumqi monitoring center has received more than 110 ten thousand field information that can be preserved permanently and queried freely after authorized. This information provides basic data for the management of large area of coal spontaneous combustion fire area in Xinjiang and for governance results defend.
