Embodiment 1

[0063] A specific embodiment of the present invention discloses a wireless laser matrix monitoring system for deformation observation of the surface area, such as figure 1 As shown, the wireless laser matrix monitoring system includes an M×N field displacement detection array composed of M×N laser detection units, a base station, and the like. Wherein, the quantities of M and N are determined according to the size of the area to be monitored and the layout requirements. Two-way data transmission is performed between the field displacement detection array and the base station through a wireless network.

[0064] The on-site displacement detection array is arranged in the surface area to be monitored, and the layout method can be uniformly arranged to monitor possible mining subsidence, landslides, cracks and other surface deformations in the surface area to be monitored.

[0065] Each laser detection unit is equipped with a corresponding independent target, and the target is s...

Embodiment 2

[0072] Optimizing on the basis of Embodiment 1, the wireless laser matrix monitoring system for surface area deformation observation also includes a solar power supply unit, a data control center, such as figure 2 shown.

[0073] The output terminal of the solar power supply unit is connected with the power supply terminal of the base station to provide power for the operation of the base station. The on-site displacement detection array is equipped with a replaceable power supply, which is replaced regularly by professional and technical personnel, and does not use a solar power supply unit for power supply.

[0074] The data control center further analyzes and displays the processing results of all base stations in different surface areas to be monitored, which helps to find the location where the deformation of the surface area first begins or is the most serious. The data control center includes a computer and supports 4G / 3G / GPRS communication. Correspondingly, the remot...

[0096] S1. On-site displacement detection arrays are arranged in the surface area to be monitored. The distance between each laser detection unit should be less than 500m, and the deformation position between the laser detection unit and the target spans the surface area, and there is no obstacle between the two; wireless data transmission The vertical height between the first antenna of the module and the ground is not less than 1m. The total number of detection nodes can be arranged according to the horizontal and vertical coordinates is 2 to 126.

[0097] S2. Arrange the base station in the surface area to be monitored. The distance between the base station and each laser detection unit should be less than 1km. The vert...

Abstract

The invention relates to a wireless laser matrix monitoring system and method for deformation observation of the surface area, which belongs to the technical field of deformation observation of the surface area, and solves the problem that the prior art cannot continuously observe the surface deformation of mining subsidence areas, landslide areas, and crack areas. The wireless laser matrix monitoring system disclosed by the invention includes an M×N field displacement detection array and a base station. In the field displacement detection array, each detection unit is equipped with a corresponding target, which constitutes a detection node. The field displacement detection array is used to obtain the ground deformation at each laser detection unit, and send it to the base station through the wireless network in the form of displacement information. The base station is used to send driving signals to control the on-site displacement detection array to collect data regularly, and receive the above information obtained by the on-site displacement detection array, and perform data processing on it. The invention can realize the continuous observation of the above ground deformation and overcome the problem of installation coupling.

Description

technical field [0001] The invention relates to the technical field of deformation observation of the surface area, in particular to a wireless laser matrix monitoring system and method for deformation observation of the surface area. Background technique [0002] Continuous observation of surface deformation in mining subsidence areas, landslide areas, and fissure areas is one of the effective ways to predict geological disasters such as mining area subsidence, landslides, and fissures. [0003] At present, two methods are usually used for automatic monitoring of mining subsidence areas, landslides, and cracked surfaces: one method is to use contact-type on-site monitoring instruments, such as pull rods, pull-rope displacement meters, magnetic extensometers, etc., combined with remote network The transmission module can realize real-time deformation monitoring of the surface area, but the disadvantage of this method is that it can only measure a single point at a time, and ...
