摘要
根据矿井巷道的传播特点,采用900 MHz射频模块PTR8000作为无线收发模块,以单片机AT89C52或AT89C2051作为微控制器,构成了固定和移动信息站(BS和MS)。通过它们之间的通信,获取移动台的位置信息;固定信息站通过CAN总线把位置信息上传到井上主控PC机,在PC机上进行处理并在电子地图上显示出来。
According to the characteristics of radio propagation in mine tunnels, the base and mobile information stations are designed in order to locate the man and vehicle in the mine tunnels, in which the 900 MHz RF module PTR8000 is adopted as the transceiver and the single - chip computer AT89C52 or AT89C2051 serve as the micro - controller. They communicate with each other and the BS gets the position information of MS. The BS will send these information to main control PC computer on the ground through CAN bus, and the PC processes the data to get the MS location and displays it on the electronic map.
