Abstract

The present invention provides an early warning method and system for fracture of a dangerous rock mass. The method includes: installing multiple sensors on the dangerous rock mass to collect rock vibration signals and posture information, and collecting the rock vibration signals and the posture information through a wireless network. The data is sent to the data processing center; the data processing center performs cross-correlation analysis on the rock vibration signals and attitude information collected by different sensors to judge the state of the dangerous rock mass. This solution solves the problems of difficulty in early warning and high cost of existing early warning methods. It can monitor and early warning dangerous rock masses in multiple areas at the same time. It can not only provide accurate early warning, but also reduce hardware costs, and is simple and easy to implement.

Description

technical field [0001] The invention relates to the field of disaster early warning, in particular to a method and system for collecting and processing fracture signals of dangerous rock masses. Background technique [0002] For mountainous landforms, fracture and collapse of dangerous rock mass is a relatively common natural disaster. Some isolated and steep hilltops with large height differences or rock masses with concave steep slopes are affected by factors such as earthquakes, weathering, and corrosion, resulting in fractures in the rock mass structure, which often cause damage to surrounding roads, buildings, or engineering equipment. May pose a threat to human life. [0003] At present, for the detection and early warning of dangerous rock mass fractures, when the rock mass is deformed, the displacement detection device is installed to provide timely early warning before the rock mass falls to ensure the safety of relevant personnel. This method is simple and low in ...
