A landslide displacement monitoring system

Abstract

The invention relates to the field of natural disaster monitoring, in particular to a landslide displacement monitoring system which comprises a measuring device, a power supply, a wireless data transmitting device, a data receiving terminal and an alarm module. The measuring device comprises a fixed rod, an accommodating box, a movable cover, a pressure sensor, an elastic medium and a strain sensor; the fixing rods are inserted into a bedrock surface, and the containing boxes are fixed to the fixing rods at intervals. And the elastic medium is positioned in the accommodating box. The soil loosening situation is detected through the shape change of the elastic medium of the measuring device, the landslide body displacement situation is detected through the change of the pressure values ofthe movable covers at the two ends, the whole process from soil loosening to landslide body displacement can be clearly monitored, and the whole measuring and alarming process is simple and clear.

Description

technical field [0001] The invention relates to the field of natural disaster monitoring, in particular to a landslide monitoring system. Background technique [0002] The methods of landslide displacement monitoring mainly include manual monitoring, instrument monitoring and remote automatic monitoring. Manual monitoring has a large workload and has large human measurement errors; instrument monitoring can measure the displacement of landslides more accurately, but most of them require special monitoring equipment, and the operation is difficult; with the rapid development of science and technology, remote automatic monitoring Systems have also begun to appear, which can realize continuous observation, automatic collection, storage, printing and display of observation data, but at present, the cost of such monitoring equipment is relatively high, and the monitoring process of some monitoring systems is relatively complicated. [0003] To improve the above problems. Conte...
