Application of the Downhole Monitoring Based on Zigbee WirelessCommunication Technology

摘要

ZigBee technology is a kind of self organization of short distance, strong anti-interference, low cost, emergingwireless sensor network application that has attracted wide attention. Therefore, this paper studies and designs a real-timepositioning system of underground personnel based on ZigBee system, the positioning of the sensor carrying minersthrough the wireless sensor network. This will help to achieve the attendance management of underground personnel, thereal-time location of underground personnel, and effectively improve the monitoring level and efficiency of disaster reliefas coal mine safety product to guarantee the life safety of the employees. According to the actual environment, the localizationalgorithms of popular wireless sensor networks were fully investigated, through the comprehensive demonstration,selection of wireless location algorithm based on RSSI, and deducing the mathematical model of the signal transmissionattenuation.
