基于对无线通信技术(ZigBee)与现场总线(CAN)技术的研究,介绍系统的构成及模块功能,以单片机作为微控制器和采用CAN总线接口转换技术,设计了一种煤矿井下人员定位系统。该系统采用新兴的ZigBee无线通信技术对井下的佩戴有标签设备人员进行定位和身份识别,由读写器采集信息通过CAN总线传送到地面监控中心,监控计算机记录人员位置信息,实现井下人员的考勤统计,并实现显示井下人员分布情况,为抢险救灾提供可靠依据和保证。
Based on the research of wireless communication technology (ZigBee) and field bus (CAN) technology, this paper introduces the system structure and module functions, and designs a coal mine personnel positioning system using microcontroller as a microcontroller and CAN bus interface conversion technology. The system uses the emerging ZigBee wireless communication technology to locate and identify underground equipment personnel who wear the tag. The information collected by the reader is transmitted to the ground monitoring center through the CAN bus. The computer records the location information of the personnel and realizes the attendance of underground personnel Statistics, and to show the distribution of underground personnel, provide a reliable basis and guarantee for disaster relief.
