A crack recognition and alarm device for collapsed bodies and its recognition method

Abstract

The invention discloses a crack recognition and alarm device for a collapsed body, which includes a control module connected to a power supply module, a crack recognition detection module and an intelligent alarm module respectively, and the control module is connected to a remote data monitoring center through a data transmission module. The invention also discloses a recognition method of the crack recognition and alarm device of the collapsed body. The invention can improve the deficiencies of the existing technology, the device is simple in operation, smart in size, convenient in installation, high in precision, low in power consumption, intuitive and visualized in data, can realize efficient identification of cracks in collapsed bodies and on-site alarm in dangerous areas of collapsed bodies, and The change of cracks in the collapsed body is found, and an alarm signal is issued in time to avoid or reduce the hazards caused by the collapse disaster to the greatest extent.

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.
