摘要
针对水情信息传输对数据传输实时性、周期性的要求以及系统数据传输量小的特点,设计了基于MC55的水情自动测报终端,包括无线通信模块与终端接口的硬件设计,数据传输软件的设计和防止无线链路掉线维持链路的实时在线方法。这种无线通信的水情自动测报终端系统具有扩充性强、可靠性高、传输速率快、实时性强等众多优点。基于GPRS网络,该终端可为水情自动化系统提供了一种高可靠、可扩展、和便于维护的通信方式。
In accordance with the characteristics of both the real-time performance and periodicity required for the data transmission of the hydrological information and the small amount transmission of system data, a MC55 module based terminal unit of automatic hydrological forecast system is designed. It includes the design of the wireless communication module and the terminal interface hardware, the design of data transmission and the real-time online method for preventing the problem of dropped call and maintaining link. This terminal unit has a lot of merits such as strong expansibility, high reliability, quick transmission rate, bet- ter real-time performance, etc. Based on GPRS network, the terminal unit can provide a reliable, expansible and easily maintainable communication means for the automatic hydrological forecast system.
