基于Crotex-M3和GPRS的远程监测系统的研究

研制出了一款运行高效、成本低、通用性较强的电梯运行状况监测系统。系统基于具有Crotex-M3内核的高性价比嵌入式系统,采集电梯各类传感器信息,获取电梯运行方向、平层状态、门状态、温湿度以及电梯内是否有人等多参数数据,再通过GPRS将数据发送至数据中心。根据电梯的运行数据,判断电梯是否正常运行,以及紧急情况下进行自动报警,实现了多区域内电梯运行状态集中监测和故障自动报警。系统实际运行效果良好,通用性强,可以满足多种型号电梯的监测。

Research of Remote Monitoring System Based on Crotex-M3 and GPRS Communication

An elevator health monitoring system with efficient operation, low cost and strong commonability was developed. Based on the cost-effective embedded system with Crotex-M3 core, informationon various types of sensors on elevator can be collected, the multi-parameter data can be got, such asthe elevator running direction, flat layer status, door status, temperature and humidity and whethersomeone is in the elevator and etc., and sent to the data center through the GPRS. The system can deter-mine whether the elevator is under normal operation according to the operating data of the elevator andhas the function of automatic alarm in an emergency. The functions of centralized monitoring of multi-zone elevator running state and automatic alarm were achieved. The system is running well and hasgood generality. It can meet various types of elevators monitoring.
