A method, device and system for determining human intrusion at railway perimeter

Abstract

The invention provides a method, device and system for determining railway perimeter artificial invasion. The method comprises the steps of collecting a detection electrical signal output by a device used for railway perimeter safety protection, performing signal demodulation processing on the detection electrical signal, determining at least one characteristic value of a shock signal in the demodulated electrical signal, and determining whether the artificial invasion occurs in a to-be-monitored protection area according to the at least one characteristic value. Since characteristic values of shock signals resulting from the artificial invasion and non-artificial invasion have a certain difference, by analyzing the at least one characteristic value of the shock signal in the detection electrical signal, whether the artificial invasion exists is determined by referring to the at least one characteristic value of the shock signal, it is not that the artificial invasion is thought to exist by determining the existence of the shock signal, so that the situation of misjudgment caused by the shock signal resulting from the non-artificial invasion can be avoided, the accuracy of identifying the artificial invasion is improved, and the conditions of misjudgment are reduced.

Description

technical field [0001] The present invention relates to the technical field of railway perimeter security protection, in particular to a method, device and system for determining human intrusion at the railway perimeter. Background technique [0002] At present, in the process of railway perimeter security protection, the monitoring of railway perimeter security protection is mainly carried out in the following two ways. One way is: arrange special staff to regularly go to the site of the railway perimeter protection zone to inspect whether there is human intrusion Another way is: install a plurality of camera devices in the perimeter protection zone of the railway to be monitored, collect the video information in the protection zone through the camera devices, and then analyze the video information by special staff to determine the railway Whether there is human intrusion in the protection zone on both sides, in order to reduce the cost of manpower monitoring, improve work ...

AI Technical Summary

Problems solved by technology

[0003] In the process of realizing the present invention, the inventor has found that there are at least the following problems in the related art: due to non-human intrusion (such as environmental factors such as wind and rain or trains passing by, etc.) can also cause on-site damage in the railway perimeter protection zone to be monitored. The signal changes, so it is impossible to accurately define whether it is a human intrusion or a non-human intrusion
