基于GPRS网络的飞机除冰液加热监控系统

针对飞机除冰液加热,设计了一种基于GPRS(通用分组无线服务)网络的远程监控系统.它可以实现对设备的实时监控,及时有效地完成飞机地面除冰.该系统由上位机和下位机两部分组成:PLC作为下位机的控制系统,对执行机构进行控制输出,并且由A/D转换模块采集加热设备管道内的物理参数;远程控制中心作为上位机的监控系统,包括两种方式:一是利用数据服务中心作为远程控制中心,二是利用组态软件设计系统的操作界面作为远程控制中心.GPRS DTU(data transfer unit)通信模块通过GPRS网络完成与远程控制中心的无线通信,实现上位机与下位机之间的数据交互.

Monitoring System of Heating for Aircraft Deicing Liquid Based on GPRS Network

A remote monitoring system for aircraft deicing liquid heating based on GPRS network is designed.It can realize real-time monitoring of the equipment,complete aircraft ground deicing effectively.This system is composed of the upper and the lower computer systems.In the lower computer system,PLC is taken as control system to control the actuator output,A/D converter module is applied to collect physical parameters.Remote control center is used as monitoring system in the upper system,which has two methods,one is to use data service center as remote control center,another is to use configuration software designed operator interface as remote control center.GPRS DTU(data transfer unit) module completes wireless communication with remote control center through GPRS network and the collected data are sent to the remote control center,then the data interaction between the two computer systems is realized.
