Collapse mass crack identification alarm device and identification method thereof

Abstract

The invention discloses a collapse mass crack identification alarm device. The device comprises a control module, wherein the control module is respectively connected with a power supply module, a crack identification detection module and an intelligent alarm module; and the control module is connected to a remote data monitor center by virtue of a data transmission module. The invention further discloses an identification method of the collapse mass crack identification alarm device. According to the device, defects in the prior art can be improved, the device is simple in operation, smart in size, convenient to assemble, high in accuracy and small in power consumption, data is intuitive and visible, efficient identification of a collapse mass crack and field alarm of a collapse mass dangerous region can be realized, the situation of collapse mass crack changes can be found as early as possible, an alarm signal can be sent out in time, and risks caused by collapse disasters can be furthest avoided or reduced.

Description

technical field [0001] The invention relates to the technical field of geological monitoring, in particular to an identification and alarm device for cracks in collapsed bodies and an identification method thereof. Background technique [0002] Collapse refers to the geological phenomenon that under certain natural and geological conditions, part of the rock and soil mass that makes up the slope, under the action of gravity, suddenly breaks away from the parent body, collapses, rolls, and accumulates at the foot of the slope (or valley). Collapses generally have obvious deformation characteristics before the collapse occurs, for example, there will be small blocks and soil rolling down at the front edge of the collapse, and partial or overall cracks may appear at the rear edge of the collapse. For the monitoring of collapsed bodies, there are methods such as deformation monitoring and physical factor monitoring. [0003] Collapses destroy buildings and sometimes entire sett...

Problems solved by technology

Infrared displacement sensors and laser displacement sensors have high requirements on electrical energy, and cannot be powered on for a long time for measurement. After a long time, the infrared sensor and laser sensor may heat up, resulting in performance degradation

Infrared displacement sensors and laser displacement sensors have high requirements for layout, and installation and construction are difficult. Accurate positioning is required to make the transmission and reception signals coincide, otherwise the measurement accuracy will be reduced, and it is not suitable for some large and dangerous collapsed bodies.
