Abstract

The invention relates to a surface collapse microseism three-dimensional positioning and monitoring method and system. The system comprises a plurality of detectors, at least one data collecting station and a control center, wherein the data collecting station is used for converting analog electrical signals collected by the detectors into digital monitoring signals and sending the digital monitoring signals to the control center through a wireless transmission network, the control center is used for receiving the digital monitoring signals transmitted from the data collecting station and conducting the focus inversion operation according to the digital monitoring signals, therefore, the focus can be positioned, and three-dimensional display imaging is achieved. The data collecting station comprises an input filter, a pre-amplifier, an analog-to-digital conversion module, a logic control unit, a data encoder, a wireless data transmission interface and a power module. According to the technical scheme, surface collapse can be easily, conveniently, timely, accurately and inexpensively monitored in real time.

Description

technical field [0001] The invention relates to ground subsidence monitoring technology, in particular to a ground subsidence micro-seismic three-dimensional positioning monitoring method and system. Background technique [0002] Ground subsidence refers to a geological phenomenon in which surface rock or soil, etc., sinks downward under the action of natural or human factors, and forms a subsidence pit or subsidence hole on the ground. When this geological phenomenon occurs in areas with human activities, it may become a geological disaster. Monitoring ground subsidence can effectively avoid the harm caused by ground subsidence to human beings. [0003] At present, there are mainly the following methods for monitoring ground subsidence: [0004] Method (1), traditional measurement method. The method is to arrange a certain number of monitoring points in the area to be monitored according to certain principles, and to measure the three-dimensional coordinates of the point...
