HP-2型滑坡遥测系统

HP-2 LANDSLIDE REMOTE-INDICATING SYSTEM

以自行研制的恒流式静态应变仪(中国专利号:88212764.0)为主机的HP-2型滑坡遥测系统,用作测值远传和分散设点集中遥测数据。本系统配接PC-1500A或IBM PC/XT计算机,可构成滑坡监测系统;它既能控制多点巡回检测、定点检测和通道号显示,亦可控制应变仪作半桥或全桥测量,又能控制采样时间等。1987—1990年运行结果表明,本遥测系统相当稳定可靠。

The key part of the HP-2 landslide remote-indicating system is a home-made static constant current strainmeter( China Patent No. 88212764. 0);the other parts include a data acquisition unit and a signal channel control unit etc.This remote-indicating system is applicable to two types of, landslide different in developing stages with attention to different remote indicating elements. The first one is the landslide that is born but tas not generated large-scale sliding. Its indicating element is to ascertain the sudden sliding time and damage area of the slide. The other one is the dangerous slope where a landslide is brewing. Its remote indicating element is to clarify the scale of landsliding deformation and moving mode and to predict the dangerous tendency of the slope. The whole system works by distributing gauges,centralizing and remotely transmitting data to facilitate the quantification of landslide studies.Connected with PC-1500A or IBM PC/XT computers,the HP-2 landslide remote-indicating system can constitute a landslide monitoring system, which controls not only the measurement in turn at many points, selecting a point measurement, display of working status and channel number,but also the strainmeter to operate in the way of half bridge or full bridge,and the sampling time. The results of running in 1987-1990 show that this remote-indicating system is stable and reliable.
