基于倾斜传感器的路基剖面沉降自动监测方法与系统
An automatic method and system for measuring and monitoring subgrade settlement using inclinometer
摘要
Abstract
Subgrade condition monitoring is a very important step to guarantee the railway safety, and subgrade settlement measuring and monitoring is an key part in subgrade condition monitoring. A new method which automatically measure subgrade settlement by using of a horizontal inclinometer was proposed in this paper. Two step motors were used to make the horizontal inclinometer move along the PVC pipe in the subgrade section, in this way, the scanning and measuring the subgrade settlement can be realized. In addition, wireless data acquisition and transmission network based on the wireless data module and GPRS data-transfer unit were built for the real-time and long-term subgrade settlement monitoring. The measuring principle, system configuration and design of software and hardware were given in the paper, and the stability and reliability of the system were verified by the laboratory experiments and field experiments.关键词
