摘　　要：由于信号在CAN总线中有效传输距离有限,为此对采用CAN总线技术的电梯远程监控系统,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的方案。通过由LPC2148和EM310组成的电梯终端将电梯的运行状况和故障信息经GPRS网络及时发送到远程监控中心,然后经由监控中心上位机软件的操作,实现了电梯的远程监控,解决了信号传输距离的问题。In consideration of the limited efficient transport distance of signals in CAN bus,a kind of elevator remote monitoring systems based on embedded ARM processor and GPRS wireless communication technology for elevator remote monitoring system that uses CAN bus is designed. Both of the elevator working status and fault information are transmitted timely to monitoring center via GPRS network through the elevator terminal units composed of LPC2148 and EM310.Then the remote monitoring and control of the elevators will be implemented by software of host computer in monitoring center and the problem of signal transmission distance will be solved.
