基于AVR的水联网智能遥测终端的设计与实现

Design&Application of the Internet of Water Intelligent Telecontrol Terminal Based on AVR

针对目前遥测终端产品通讯信道单一、可监测参数少等问题,本文介绍了一种基于AVR单片机的水联网智能遥测终端设计思路。采用GPRS网络作为主信道、北斗卫星作为备用信道,有效提高了数据传输的可靠性;通过485总线接口,实现了流量、图像等智能传感器的接入,扩展了监测参数的种类;设备通讯协议严格执行水利部最新颁布的《水文监测数据通信规约》要求,可在多种不同平台下使用,设备已成功应用于海南山洪灾害非工程措施建设项目,具有良好的市场前景。

In view of the present problems in telemetry terminal products such as single communication channel and less monitoring parameters, this paper introduces an intelligent design thinking of water networking based on AVR. Using the GPRS as the main channel, the Beidou satellite as the standby channel, effectively improve the reliability of transmission;By 485 bus interface, realize the access of intelligent sensors, extend the types of monitoring parameter;Device communication protocol strictly carry out the ＂Hydrological Monitoring Data Communication Protocol＂most recently issued by the MWR;Devices can be used in a variety of different platforms and has been successfully applied to non-engineering construction projects against flood disasters in Hainan Province, with good market prospects.
