摘要
用传感器对滑坡实施监测是一种有效的监测预警手段,但由于受一些因素的限制,在实验室进行滑坡监测技术有效性的研究方面仍有一定的难度。本文以振弦式传感器为例,提出了传感器辅助机械工装以完成传感器在实验室实现滑坡监测数据模拟采集的设计思路,并通过对模拟数据进行多次测量演算了传感器及其辅助装置的可靠性。同时,为便于对监测数据进行及时有效的管理和分析,还采用VC++语言所编制的管理程序对获取的监测数据实施有效的管理和分析。结果表明,对给定信号的监测效果好,响应快,误差小,能较好地模拟滑坡现场监测。
Using the sensors to monitor the landslide is an effective warning tool.However,due to the limitations of the environment it is very difficult to research the monitoring techniques in the laboratories.Based on the monitoring points of the vibrating sensors in the slope,a fixture（tooling） were designed to make it a good job in the lab.It can help to produce the simulation data.After being tested many times,the data showed that the sensors and the fixtures（toolings） were stable and reliable.And in order to manage and analyse the data well,designing an interface is a good way by using the VC ＋ ＋ programming,which can analyzed and manage the data from the sensors and find some data that changed dramatically.As a result,as a whole the system can represent landslide site effectively and monitor the signs as soon as possible with less errors.
