Development of Remote Automatic Monitoring System for Subgrade Settlement
摘要
Abstract
A remote automatic monitoring system for subgrade settlement is researched and developed based on the techniques of laser measurement, advanced sensor and wireless network, etc. The monitoring system is composed of automatic laser measurement subsystem for surface settlement, simultaneous automatic measurement subsystem for subgrade layered settlement and lateral displacement, automatic measurement subsystem for the transverse section settlement of subgrade, and data acquisition and wireless transmission subsystem. The automatic measurement of surface settlement is realized by adopting the techniques of laser measurement and automatic calibration. The simultaneous automatic measurement of subgrade layered settlement and lateral displacement is achieved by using Hall sensor, laser ranging and tilt sensor. The automatic measurement of subgrade transverse section settlement is accomplished by the tilt sensor driven by master and slave motors. Field experiments were carried out in Jinan West Station of Jing-Hu highspeed railway after the lab verification and engineering design of the monitoring system. The long-term, comprehensive, remote automatic monitoring of subgrade settlement including total settlement, local settlement and different layer settlement of section has been realized.关键词
