基于北斗短报文的弱信号台区数据采集系统

Data acquisition system of weak signal station area based on beidou short message

利用基于GPRS系统在弱信号台区进行数据采集,存在采集范围小、数据传输成功率低的问题。针对上述问题,设计一个基于北斗短报文的弱信号台区数据采集系统。系统框架主要包括数据采集终端、数据传输、数据处理终端三个部分,每个部分相对的硬件为数据采集硬件、信号传输硬件以及数据处理硬件,每个硬件相对的软件有采集程序、传输程序、主站处理与控制程序。采集程序采集弱信号台区数据,处理后将其发送给传输程序,接着经北斗卫星转发到主站进行处理与控制,完成数据采集。结果表明:与基于GPRS系统相比,本系统采集范围扩大40 m^2,数据传输成功率提升3.13%。

There are some problems such as small acquisition range and low success rate of data transmission in GPRS system,which is used to collect data in weak signal area.In order to solve the above problems,a weak signal station area data acquisition system based on Beidou short message is designed.The system framework mainly includes three parts:data acquisition terminal,data transmission and data processing terminal.The relative hardware of each part is data acquisition hardware,signal transmission hardware and data processing hardware.The relative software of each hardware has the acquisition program,the transmission program,the main station processing and the control program.The acquisition program collects the weak signal station area data,and sends it to the transmission program after processing.Then it is trany mitted to the main station for processing and control through the Beidou satellite,and data acquisition is completed.The results show that,compared with the GPRS system,the acquisition range of the system is expanded by 40 m^2,and the success rate of data transmission is increased by 3.13%.
