摘要
人员定位系统由标识卡、监测分站和监控中心三部分构成,当井下人员经过安装在各个采区口的监测分站时,随身携带的标识卡将卡片中的个人信息发送出去,由监测分站采集到信息并存储,当监控中心主机发送命令来获取数据时,通过总线送到地面控制中心。这里主要介绍标识卡的设计方法。标识卡采用单片集成无线收发模块nRF24L01为射频前端,以低功耗单片机MSP430F2011为控制器,以LED和蜂鸣器为状态指示。介绍了硬件设计和软件的编程方法,最后进行了验证。
The device is composed of radio frequency identification card,monitoring substation and control center. When a miner passes through a monitoring substation,his portable identification card will send his information out,and monitoring substation collects the information. It waits for request of monitoring center′s PC after saving information,and uploads data in memory to the PC once receiving commands. The nRF24L01 is adopted as the RF frontend which is a single chip wireless transceiver,lo power consumption MSP430f2011 as the main controller,LED and buzzer as the status indication. The hardware design and software programming methods are introduce in this paper. They passed the verification.
