Dangerous rock mass acousto-optic combined intelligent monitoring and early warning method

Abstract

The invention relates to the technical field of dangerous rock mass monitoring and early warning, in particular to a dangerous rock mass acousto-optic combined intelligent monitoring and early warning method. The method comprises the steps of S1, selecting an object, specifically, selecting a dangerous rock mass below which a threatened object exists; S2, installing instruments, specifically, installing an alarm instrument on a stable mountain body on the inner side or the side of the dangerous rock mass, wherein the alarm instrument comprises a control module, and installing a monitoring instrument on the dangerous rock mass or between the dangerous rock mass and the mountain body; and S3, performing initial data acquisition, specifically, acquiring data of the size, shape, height, inclination direction, inclination angle, displacement, crack width, landform conditions of the dangerous rock mass and distribution of threatened object through two modes, namely, the monitoring instrument and manual observation, and inputting the manually acquired data into the monitoring instrument. According to the technical scheme, the dangerous rock mass is monitored in real time, meanwhile, when the dangerous rock mass collapses, a sound-light alarm signal is sent out at the first time, a safe escape path is pointed out to threatened people, and the personal safety of the people is ensured.

Description

technical field [0001] The invention relates to the technical field of dangerous rock mass monitoring, in particular to an intelligent monitoring and early warning method combining sound and light for dangerous rock mass. Background technique [0002] Although some rock masses have not yet collapsed, they have the main conditions for collapse, and there have been signs of collapse, so it is predicted that a collapse may occur in the near future. Such rock masses are called dangerous rock masses. Dangerous rock mass is a potential collapse mass. The main basis for its discrimination is: large height difference, or the slope body is an isolated and steep hilltop, and there is a concave steep slope with a huge free surface in front of the slope body; cracks are developed in the slope body, the rock mass structure is incomplete, and a large number of them are consistent with the slope inclination Or parallel extending fissures or weak zones; the collapse at the foot of the slop...

AI Technical Summary

Problems solved by technology

[0003] Because the collapse of the dangerous rock mass is uncertain, if it collapses without the knowledge of the masses within the range of the collapse, it will cause great casualties and losses. The existing devices usually adopt the method of sound and light monitoring and early warning. Although the masses can feel the danger warning, they cannot accurately perceive the threat range of the dangerous rock mass. Therefore, when the dangerous rock mass is warned, The masses can only evacuate according to subjective feelings or the path suggested by the daily training of the management department or professional technicians

In addition, if the collapse path of the dangerous rock mass changes, it is impossible to inform the masses of the new evacuation path at the first time, and the danger cannot be avoided.
