Abstract

The invention discloses an on-line monitoring and early warning instrument for cracks in buildings on the surface of geological disasters. It includes a bottom plate, and half of the bottom plate is fixedly equipped with equipment boxes, batteries and sound and light alarms. There is a window on the other half of the bottom plate, and the window corresponds to the other side of the crack in the wall; an installation liner is fixedly installed in the equipment box, and sensors, control boards and GPS modules are fixedly installed on both sides of the installation liner respectively. A digital display is installed on the inner side of the panel of the equipment box, and an external antenna is installed on the upper surface of the equipment box; the transmission rod of the sensor passes through the right side panel outwardly, and the outer end of the transmission rod is installed with a universal joint. It is connected with the fixed pile of the wall through the steel wire. The device of the present invention realizes the automatic detection of the crack state, has good real-time performance and high accuracy, and solves the problem of no stable external power supply at the monitoring site, and can continue real-time monitoring and timely on-site alarm.

Description

technical field [0001] The invention belongs to the technical field of crack monitoring equipment, and is used for monitoring and early warning of cracks in surface buildings of geological disaster bodies, and in particular relates to an online monitoring and early warning instrument for cracks in surface buildings of geological disaster bodies. Background technique [0002] In the existing geological disaster group survey and group prevention, the means of monitoring and measuring ground or wall cracks is mainly to set up a scale on the measured object, rely on the monitor to use a tape measure to perform manual measurement, and finally after statistics and processing of the observation data, Realize qualitative observation. Due to the influence of personnel experience and on-site status, the accuracy and frequency of measurement data cannot be guaranteed due to manual detection, and the real-time performance is poor and the accuracy rate is low. Moreover, the measurement ...
