A monitoring system and method for personnel intrusion in key areas of coal mines

Abstract

The invention discloses a personnel intrusion monitoring system and a method thereof in a key underground area of ​​a coal mine, comprising an underground wireless access point, a CSI information receiver, and an above-ground monitoring server; the underground wireless access point is installed in the underground key area , the CSI information receiver collects the CSI information of the downhole wireless access point and transmits it to the uphole monitoring server through the downhole wireless network; the uphole monitoring server processes the CSI information and communicates with the uphole monitoring Compare the CSI information processing results between the pre-set unmanned and occupied situations in the server to determine whether there is any intrusion. The present invention uses the channel state information of the physical layer of the wireless access point as a monitoring means to monitor whether there is personnel intrusion. The equipment used is simple, and some mines even only need some simple modifications to complete the system deployment. The deployment cost of the system is low, and the monitoring accuracy is high.

Description

technical field [0001] The invention relates to the field of underground monitoring of coal mines, in particular to a monitoring system and method for personnel intrusion into a key area of ​​a coal mine, specifically, by using the physical layer information of a wireless access point as a detection means to monitor whether there is an illegal intrusion in a key area , so as to protect the safety of key areas. Background technique [0002] There are many underground areas in coal mines, and the environment is complex. Some areas are used to store key material equipment. Without relevant authorization, no one is allowed to enter this area. Therefore, these key areas need to be monitored intensively. Traditional surveillance methods mainly include video surveillance and infrared surveillance. However, due to poor light and illumination underground, clear video content cannot be transmitted, and even in some areas due to the particularity of storage materials, it is not possib...

AI Technical Summary

Problems solved by technology

It is especially suitable for scenarios where the video monitoring system cannot capture accurate pictures due to unfavorable and ideal environments, and the video monitoring cannot be performed due to the particularity of the monitoring area.
