Mountain Monitoring Early Warning/Alarm System

Abstract

The invention relates to a mountain monitoring early warning / alarm system comprising a stable end base which is installed at a mountain stable end; a moving end base which is installed at a mountain moving end; a sensor module which is installed on the stable end base and comprises three laser sensors which emit laser beams along three coordinate axis directions of a three-dimensional coordinate system; three laser reflecting plates which are installed on the moving end base and respectively positioned on the light paths of the laser beams emitted by the three laser sensors; and onsite control equipment which is connected with the sensor module and used for receiving distance signals transmitted by the sensor module and calculating displacement of the mountain moving end in the three-dimensional coordinate system according to the distance signals and transmitting early warning / alarm information to background equipment according to the displacement. Timely and accurate early warning and alarming of the mountain deformation phenomenon can be performed and the phenomena of false alarm and failure alarm can be avoided, and the mountain monitoring early warning / alarm system also has the characteristics of being convenient to install, low in realization cost and stable in field working performance.

Description

technical field [0001] The invention relates to a geological disaster monitoring technology, in particular to a mountain monitoring early warning / alarm system. Background technique [0002] Mountain deformation geological phenomena such as mountain cracks and collapses usually have serious hazards, such as changing river courses, forming barrier lakes, and endangering human life and property safety. [0003] In order to reduce the hazards caused by mountain deformation geological phenomena such as mountain cracks and collapses, the mountain is usually monitored so that early warning of mountain deformation geological phenomena can be carried out as early as possible, so that the hazards can be reduced by taking corresponding measures as early as possible. [0004] At present, there are mainly three ways to monitor and warn mountains: [0005] Method 1. Pressure monitoring and warning technology; that is, a pressure sensor is installed under the mountain that is prone to mou...

Problems solved by technology

[0009] Although the above-mentioned method 1 can monitor the geological phenomenon of mountain deformation at low cost, since the pressure sensor can usually only measure the pressure change in the vertical direction, it usually produces false alarms when the mountain is displaced.

In addition, since the pressure sensor needs to be placed under the mountain, it is often difficult to install the pressure sensor in the actual field, especially when the mountain that is prone to collapse is suspended at a high position, the installation of the pressure sensor is particularly difficult

[0010] In the above method 2, the power consumption of video equipment is usually large, and it is usually difficult to power video equipment for a long time in the wild

In addition, since moving objects in the real environment will interfere with image analysis, this method often mistakes moving non-collapsing bodies for collapsing bodies or mistaking collapsing bodies for moving non-collapsing bodies, thus Affected the accuracy of the alarm

In addition, although this method can realize the alarm of mountain deformation geological phenomena, there are deficiencies in the early warning of mountain deformation geological phenomena.

[0011] In the third method above, when installing the displacement sensor and the baffle, it is necessary to continuously adjust the contact strength between the displacement sensor and the baffle, which makes the installation difficult

In addition, due to the high requirements on the materials of the components, this method makes the implementation cost high. For example, the elastic coefficient of the elastic components inside the displacement sensor should remain unchanged for a long time under the pressure environment. And the deformation cannot be easily broken due to excessive rigidity

In addition, due to the fact that the field environment is easy to cause aging and corrosion of the displacement sensor (such as the internal elastic element) and the contact baffle, this method often has the problem of insufficient displacement measurement accuracy, and the warning of the geological phenomenon of mountain deformation is accurate. sex has adverse effects
