The Design and Optimization of Underground Scraper Wireless Monitoring Networks Based on Zigbee

A wireless monitoring network for underground scrapers on the basis of Zigbee is designed. According to the RSSI value in ZigBee networks, scrapers’ coarse positioning is calculated, which is transmitted to mounted computers’ main control unit, and with mounted sensor's data, scrapers’ position and state is evaluated.By means of WLAN, scrapers’ video monitoring data, telecontrolling data and scapers’ position and state data are transferred between ground-based computers and mounted computers, so as to achieve the function of scapers’ BVR telecontrol/unmanned autonomous walking, which is effective in simulation experiments.
