一种隧道位移激光定位自动监测系统

Development of Laser Positioning and Automonitoring System for Tunnel Displacement

借助激光定位原理,融合单片机技术、传感器技术、调制解调技术和串行通信等技术,研制开发了一种隧道位移远距激光定位自动监测系统,利用普通电话线可以在相距约10km的隧道和监测站之间进行数据通信,并能在终端计算机上进行远距离控制循环监测、数据记录查询等,极大地提高了监测实时能力。现场运行表明该系统具有可靠性高和传输速度快、成本低、使用方便和维护性好,满足了工程需要。

Combined the technologies of laser, single-chlp microcomputer, MODEM and communication, a new kind of remote laser displacement auto-monitoring system for tunnel was developed, using common twisted-pair lines as commtmicafion circuitry, which made the data commtmication available between the monitoring station and the tunnel located 10 km away. Realize the remote controlling, circularly monitoring and record database query, etc. From actual working, make a conclusion that it is not only sampling design of system, but shorting the delay-time, improving the stability and reliability,preponderant than others in use and maintenance.
