基于GPRS技术的设备远程监控系统

阐述了一种基于GPRS/GSM网络的远程数据传输方案,以此方案实现了对无人职守设备实施的24 h监控,并对其工作原理进行了探讨。分布于不同地理位置的监测终端借助于GPRS网接入Internet网络与控制中心实现远程数据传输,既担负对监控设备对象的监测,又作为远程终端通过GPRS Modem与控制中心建立起用于传输数据的TCP/IP连接,并通过此连接接收监控中心命令,或者发出设备检测信息数据。系统地分析了ARM7控制器信号采集接口与GPRS MODEM的连接设计,对监控终端工作原理及其控制模块作了分析。

Long-distance Monitoring System of Equipment Based on GPRS Technology

A long-distance data delivery plan via net based on GPRS/GSM was introduced,the unmanned controlling equipment was monitored all the day for 24 h by this plan and its working principle was discussed.Long-distance data delivery between controlling center and Internet through GPRS is realized from the monitoring terminals of different geological positions.This system not only monitors the object of the equipment but also connects TCP/IP of data delivery between long-distance terminal GPRS Modem and controlling centers,while the monitoring center order is received by this connection or sends information data of checking equipment,and the connection design between ARM7 controlling signal collection port and GPRS MODEM was systematically analyzed.Working principle of monitoring terminals and its controlling module was analyzed in detail.
