Abstract

The utility model discloses a device for monitoring dangerous rock body collapse by utilizing a video recording method. The device comprises a wireless night vision camera, markers, a signal receiver and a terminal computer, wherein the wireless night vision camera is fixed at the crack stabilization side of the dangerous rock body; the markers are arranged at two sides of the crack of the dangerous rock body; the wireless night vision camera records the crack continuously and wirelessly transmits the recording to the signal receiver; and due to the signal amplification function of the signal receiver, the recorded video is transmitted to the terminal computer through long distance, the distance data and crack change data between the marker are automatically searched on video processing software and are further analyzed and processed, and the crack width change curve of the dangerous rock body is drawn, so that the collapse of the dangerous rock body is accurately monitored in real time. The device has the advantages that the data is wirelessly transmitted and monitored in real time, the device is simple in structure, high in monitoring precision, safe, easy to operate and low in requirements on the monitoring environment, and the image data can be acquired at the first time during emergency.

Description

A kind of device that utilizes the avalanche of video recording method monitoring Dangerous Rock Body
Technical field
The utility model relates to Dangerous Rock Body avalanche monitoring field and video acquisition processing technology field, relates in particular to a kind of device that utilizes the avalanche of video recording method monitoring Dangerous Rock Body.
Background technology
The safety monitoring research of Dangerous Rock Body is long-standing, its monitoring method also has several different methods, traditional method adopts milscale observation intuitively, directly directly measure exactly the fracture width variation of Dangerous Rock Body with milscale, among measuring method intuitively simple, but have low precision and the problem such as can not record.
Along with further developing of science and technology, GPS, INSAR three-dimensional laser scanner etc. also is introduced in the safety detection of Dangerous Rock Body, although the collection of data is convenient, but precision still can not fine satisfied monitoring requirement, and cost is expensive, in the engineering application of reality, still can not play the effectiveness of good monitoring and forecasting for the avalanche of Dangerous Rock Body.
The utility model content
The utility model is in order to solve the problems referred to above in the existing engineering in Dangerous Rock Body avalanche monitoring field, a kind of device that utilizes the avalanche of video recording method monitoring Dangerous Rock Body is provided, the utility model is the field of characteristics introducing safety monitoring intuitively in real time of video, in conjunction with software program, successfully realize efficiently the Real-Time Monitoring to the Dangerous Rock Body avalanche, have simple in structure, safety is easy to operate, precision is high, with low cost, data are directly perceived, realize wireless penetration, and are low to the periphery monitoring environmental requirement, can obtain in the very first time advantages such as Dangerous Rock Body crack field image.
To achieve these goals, the utility model adopts following technical scheme.
The device of utilization picture recording method monitoring Dangerous Rock Body of the present utility model avalanche comprises wireless night vision cam, marker, signal receiver and terminal computer; Wireless night vision cam is fixed in the Dangerous Rock Body crack stablizes side, and marker is placed in both sides, Dangerous Rock Body crack, between wireless night vision cam and signal receiver, communicate by letter between signal receiver and terminal computer.
Installing of many these devices of group can form the wireless video real-time monitoring system, further more comprehensive and accurate monitoring Dangerous Rock Body avalanche.
Described wireless night vision cam satisfies waterproof, anti-high temperature, anticorrosion, the requirement such as tamper-proof, can common rugged surroundings in the open air in continuous firing longer time even about fortnight.
Described marker firmly is fixed on both sides, Dangerous Rock Body crack, and waterproof, anti-high temperature, anticorrosion, the requirement such as tamper-proof.
Described signal receiver fixed in position is in safer fixed position point, in the open air longer time even continuous firing fortnight in common rugged surroundings.
The method of utilization picture recording method monitoring Dangerous Rock Body of the present utility model avalanche comprises the steps:
(1) choose tested point on the Dangerous Rock Body crack, fixedly install marker in its both sides, wireless night vision cam is fixed on the Dangerous Rock Body crack to be stablized near the side marker, control camera lens and determine engineer's scale to the distance of marker, and the assurance marker is in the optical center;
(2) picture data in camera collection Dangerous Rock Body crack, and be wirelessly transmitted to simultaneously signal receiver, after amplifying through signal, the more wireless terminal computer that is sent to;
(3) terminal computer passes through the range information between Video processing automatic search extraction marker, thereby provides the real-time width in Dangerous Rock Body crack, and draws out image.
Described wireless night vision cam twenty four hours uninterruptedly carries out the real-time recording monitoring to the Dangerous Rock Body crack.
Described Video processing is, extracts in picture distance between marker at interval of N second (self-defined setting) automatic search, and automatically calculates according to engineer's scale and be converted into actual distance.
The utility model is by the uninterrupted also view data in wireless transmission Dangerous Rock Body crack that gathers of wireless night vision cam, signal amplification through signal receiver, be sent to terminal computer, by Video processing software, variable in distance between the automatic search marker, calculate the width in actual Dangerous Rock Body crack according to engineer's scale, and provide at last the change curve image of fracture width, realize efficiently the wireless penetration Real-Time Monitoring to the Dangerous Rock Body avalanche.In addition, organize installing of this device more, can also form the wireless video real-time monitoring system, further more comprehensive and accurate monitoring Dangerous Rock Body avalanche.
The beneficial effects of the utility model are, successfully realize efficiently the Real-Time Monitoring to the Dangerous Rock Body avalanche, have simple in structure, safety is easy to operate, and precision is high, and is with low cost, data are directly perceived, realize wireless penetration, and are low to the periphery monitoring environmental requirement, can obtain Dangerous Rock Body crack field image in the very first time.
