Development and study on settlement remote monitoring and controlling system based on general packet radio service

针对当前沉降测量技术、信息采集及传输技术应用于土木工程远程监控系统的现状,基于高档单片机技术及GPRS通信技术,设计开发了由磁致式静力水准仪、数据采集传输设备及数据中心组成的沉降远程自动监控系统。通过试验对采集数据系统的传输稳定性和精度进行了分析,表明系统具有数据存储量大、GPRS传输稳定、精度高、成本低、对环境温度适应性强的特点,满足土木工程沉降监测要求,是一种综合性能较优的远程自动监控系统。

Considering the settlement measuring technology,cable and wireless transmission technology application and research status in field of civil engineering at present,a new settlement remote monitoring and controlling system was developed based on high grade single-chip microcomputer technology and GPRS internet communication technology. The system consisted of magnetic type hydrostatic leveling sensor,data acquiring and transmission device,and data collection centre. The acquiring data transmission stability and accuracy were analyzed by experiment. The result showed its large data storage capacity,stable GPRS transmission,high accuracy,low cost and easily adapted to environment. All the characteristics mentioned above met for the demand of civil engineering settlement monitoring. It is a better long distance automatic monitoring and controlling system with comprehensive performance.
