摘要
以金沙江下游梯级水电站水情自动测报系统为例,介绍了梯级水电站大型水情自动测报系统遥测站的通信需求,并分析了此类系统的特点和实现的难点。针对通信组网的实现、时序的设计、回执的获取、数据包的压缩格式等难点提出了相应的解决方案,并阐述了具体实现的方法,为同类系统的建设提供了经验。
Taking the hydrologic data acquisition system of cascade hydropower stations on the downstream of the Jinshajiang River for example,the telemetry requirement of a large hydrologic data acquisition system of cascade hydropower stations is introduced. The characteristics of and difficulties in the system design are also analyzed. The corresponding solutions for the difficulties in telemetry networking,design of scheduling,receiving of ack and compression format of data packet are put forward. This paper provides experience for the construction of similar systems.
