摘要
为了解决信号在CAN总线中的有效传输距离有限的问题,提出了一种基于嵌入式ARM处理器和GPRS无线通信技术的电梯远程监控系统方案。该方案通过LPC2148和EM310组成的电梯终端来将电梯的运行状况和故障信息经GPRS网络发送到远程监控中心,然后对监控中心上位机软件进行操作来实现电梯的远程监控,从而解决了信号传输的距离问题。
In order to solve the limitation of effective signal transmission distance in CAN bus, an elevator remote monitoring system based on embedded ARM processor and GPRS wireless communication technology is designed in this paper. The elevator terminal is composed of LPC2148 and EM310. The elevator working status and the fault information are transmitted to the monitoring center via GPRS network. Then the remote monitoring and control system of the elevators is implemented by the software in monitoring center, Thus the problem of signal transmission distance was solved.
