摘要
本文基于GPRS的远程监控系统中,通信链路为GPRS网络,虽然GPRS登录Internet后具有始终保持在线通道,但也会因网络故障、信号不强、闪电等原因,而出现下网即掉线,为保证系统的可靠稳定的运行,本文提出了解决上述问题的软件实现办法。利用"心跳"程序,定期检查联网情况,一旦出现掉线,及时自动重新连接网络,保证远程采集前端与监控中心的稳定连接。
In the remote monitor system based on GPRS technology,the communication link is the GPRS network.After GPRS login in internet,it is always on line,but also lost connection,i.e.fall line because of fault network,weak signal,lightning and other reasons.To ensure the reliability and stability of the system,the paper proposed an idea to solve the above problem by use of software.It can detect the network condition periodically applying heartbeat procedures,once the connection dropped,it can be networked automatically so that the long-distance data acquisition and monitoring center are connected stably.
