In view of the disadvantages of the prevention and control technology of spontaneous combustion in goaf

a wireless temperature monitoring system based on Zig Bee technology is designed.The system nodes revolve around CC2430

end nodes sense the temperature of goaf in mine by temperature sensor DS18B20

datas are sent to routing nodes from end nodes by the way of wireless

and routing nodes gather the datas to coordinator node via multi-hop.coordinator nodes transmit the processed temperature data to the host computer through CAN bus.The system has the advantage of low cost

high reliability

easy networking.This system provide an effective way to monitor the temperature and prevent of spontaneous combustion in goaf.
