北斗通信模块在盐湖水文采集系统中的应用

无公网覆盖的偏远地区是盐湖水文数据采集的一个难题。介绍了一种基于北斗短报文通信的北斗模块盐湖水文采集系统,系统包括主站点和若干个子站点。子站点中设备按照北斗报文规定通信协议,配置北斗模块的波特率,完成时间查询、数据通信功能。子站点中北斗模块在设备控制下和主站点中北斗模块进行数据通信,主站点中北斗模块接收到信息后转发给接收设备,接收设备进行数据拆包,转发给手机存储、检测。以西台盐湖地区采集系统为例,分析一年来水温、水位和太阳辐射等数据,剖析北斗模块盐湖水文采集系统在目前应用中存在问题以及保障措施。

Application of Beidou Communication Module in Salt Lake Hydrologic Collection System

Most of the salt lakes are located in isolated areas without public network coverage,thus it is difficult to collect the hydrologic data of salt lakes.In this paper,a hydrological collection system of salt lake based on Beidou short message communication is introduced.This system consists of the main station and several sub-stations.According to the communication protocol of the Beidou message,the equipment in the sub-station shall configure the Baud rate of Beidou module,and complete the functions of time query and data communication.Under the control of the equipment,the Beidou module in the sub-station carries out data communication with the Beidou module in the main station.After receiving the information,the Beidou data in the main station is forwarded to the receiving equipment,which unpacks the data and forwards it to the mobile phone for storage and testing.Taking the collection system of West Taijinar Salt Lake area as an example,through the analysis of data on water temperature,water level,solar radiation,etc.,the problems and supporting measures in the application of Beidou module salt lake hydrological collection system are analyzed.
