GPRS无线通信远距离输水工程后备通道的探讨

摘要

以河北省南水北调配套远距离输水工程监测系统为例，探讨在现有光纤通信技术的基础上探索通过中国移动GPRS无线通信网络建立可靠无线通信备用通道的可能性，以便在光纤通信系统故障时，可以进行数据传输的无缝切换，保障自动化系统的通信传输畅通，确保监测系统的正常运行。%This paper aims at the monitoring system of the South to North Water Diversion Project, and discusses the pos-sibility of establishing reliable wireless communication network through the existing optical fiber communication technolo-gy, in order to ensure the seamless handover of data transmission and ensure the normal operation of the monitoring system in the communication system of GPRS.
