Abstract

The invention provides a landslide real-time monitoring system. The system comprises a measurement device, a communication network system and a monitoring computer, wherein the measurement device comprises a linear displacement sensor, a movable strut, a fixed strut, a connecting belt, collectors and the like; the communication network system consists of a ZigBee coordinator with a general packet radio service (GPRS) module and a plurality of ZigBee terminal nodes; the ZigBee coordinate and the ZigBee terminal nodes form a field ZigBee network; and the ZigBee terminal nodes are the collectors in the measurement device. When landslide causes surface displacement, the length of the connecting belt varies, the variation can be measured through the linear displacement sensor, and landslide information collected by the collectors is transmitted to the monitoring computer of a monitoring center through the field ZigBee network. The surface displacement information is acquired by utilizing the linear displacement sensor, so the device has the characteristics of all-weather real-time monitoring, high measurement accuracy and low price.

Description

technical field [0001] The invention relates to a real-time monitoring system for landslides, in particular to a real-time monitoring system for surface displacement caused by landslides. Background technique [0002] Due to the special geological structure, landslides have become the most widespread secondary geological disaster in western my country. Landslide monitoring is to predict the trend of landslides through various technical methods, and it is the main means of preventing landslides. Through landslide monitoring, we can understand and master the evolution process of landslides, capture the characteristic information of landslide disasters in time, and provide scientific basis for landslide prevention. At present, among the technical methods used for landslide monitoring, the manual measurement technology is not only low in automation and heavy in labor, but also cannot realize real-time monitoring; although the GPS measurement system solves the problem of real-ti...
