Embodiment

[0115] In this embodiment, a ground acquisition station is arranged in the warning area to collect seismic signals, the acquisition station transmits the collected vibration data to the host computer in real time, and the host computer processes the data to realize the functions of early warning and positioning of intrusion targets. The acquisition station needs to use a single-component detector that can transmit data in real time. The acquisition stations need to be arranged in a certain array, and it is defined that each minimum vibration area is composed of four detectors of one or more acquisition stations, and the four detectors (collection channels) form a square array with a fixed side length. According to actual needs, when the warning area is small, only one vibration area can be used to achieve block positioning; when the warning area is large, multiple such vibration areas are used to cover the entire area. And two adjacent vibration areas can share two detectors o...

Abstract

The invention belongs to earthquake positioning technology, and in particular relates to a method and system for quickly locating ground intrusion targets. The method includes: arranging at least one equilateral long square vibration area in a matrix in the warning area; judging the vibration area where the earthquake point appears ; If the shock point appears in at least one equilateral long square shock region in the matrix arrangement, then obtain the seismic wave signal amplitudes of the four vertices of the shock region where the shock point occurs, find the vertex where the maximum seismic wave signal amplitude occurs, and use the maximum seismic wave signal amplitude The position of the apex that appears is the base point, one half of the side length of the vibrating area is used as the first positioning side length, and one quarter of the area of ​​the vibrating area is used as the first positioning range. The invention realizes intrusion target positioning and can improve positioning efficiency, and the way of block positioning also solves the possible situation that the TDOA positioning equation has no solution. And within a certain range, it can improve the accuracy of vibration location of ground intrusion targets.

Description

technical field [0001] The invention belongs to seismic positioning technology, and particularly relates to a method and system for rapid positioning of ground intrusion targets. Background technique [0002] Ground vibration positioning systems have important applications in many fields, especially in the military. Based on this passive passive detection, the ground battlefield sensor was born. This sensor can monitor the ground motion signal generated by the target, and then complete tasks such as preventing others from intrusion, target positioning, and searching. The application of this anti-intrusion method to the area that needs to be monitored can greatly save manpower and material resources. In some other fields, such as bank vaults, prisons and even family homes, where monitoring and management are required, this anti-intrusion method is also effective. The location of the vibration target is mainly composed of two parts: one is to pick up the first arrival of the...
