基于CAN总线井下人员定位系统的设计

Design of Positioning System for Underground Mine Personnel Based on CAN Bus

基于无线通信和嵌入式技术,设计一种煤矿井下人员定位系统。采用微功率固定收发模块,实时采集井下工作人员佩戴的微功率定位信号发射器发出的数据,然后固定收发模块将采集到的信息通过CAN总线和以太网传送到上位机,上位机通过对数据信号的分析,实现对井下人员的定位。此系统具有功耗低、可靠性高的特点,满足了矿井人员定位的要求。

Based on the Wireless Communication and Embedded technology, a coal mine personnel positioning system was designed. It uses Micro-power transceiver module to collect real-time positioning signals, which is sent by micro-power transmitters fixed on the person in the underground. Fixed transceiver module transmits the information through the CAN bus and the Ethemet bus to the PC, then the data were analyzed by PC and the position of underground staff were located. The system is characterized by low-power dissipation, high reliability, which meets the mine personnel positioning requirements.
