[0006] However, the existing means of perimeter prevention mainly include microwave radiation, radar, leaking cables, video analysis, high-voltage power grid, etc. Vibration detection of prison isolation nets is a relatively new perimeter monitoring method. The products currently on the market, They all detect the vibration amplitude of the prison isolation net, and do not filter out the vibration generated by the environment and machinery. Therefore, there are many false positives

Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0037] Such as figure 1 As shown, the schematic diagram of the system structure of the prison isolation network vibration analysis method, which includes a data processing module, an expert analysis module and a vibration monitoring terminal.
[0038] Vibration monitoring terminal: It is a hardware device designed with high integration and ultra-low power consumption. This device is installed on the prison isolation network, collects environmental data on the prison isolation network, and then uploads the data to the data processing module.
[0039] The expert analysis module is connected to the data processing module, and the data processing module encapsulates the device data collected by the terminal and transmits the data to the expert analysis module. The expert analysis module analyzes the vibration data, distinguishes the vibration interference ...

The invention discloses an analysis method based on jail separation net vibration. Whether environmental factors or noise factors or human factors exist or not is judged by detecting the vibration acceleration standard deviation and the variable coefficient of vibration detecting points; the vibration of a jail separation net can be detected, monitored vibration data of a plurality of positions of are analyzed, the vibration interference caused by inhuman factors such as wind, rain, hail, building construction, large equipment, vehicles and detonation are eliminated, and the false alarm rate is reduced; the vibration caused when prisoners cross over and damage the isolation net is analyzed and alarmed, an operator on duty is reminded to handle the situation in time, and the safety of the surrounding of a jail is guaranteed.
Description
technical field [0001] The invention relates to an analysis method based on the vibration of prison isolation nets. Background technique [0002] Wall security protection belongs to the category of perimeter intrusion detection. With the development of society and technological progress, many technologies have been applied to perimeter intrusion detection. [0003] The prison isolation net is installed on the inside of the prison wall, about 5 meters away from the prison wall. It is the first barrier for prisoners to escape from the prison over the wall. The net vibrates. [0004] However, there are many reasons for vibration, including wind, rain, hail, construction, large equipment, vehicles, blasting and other non-human factors, as well as vibration caused by prisoners jumping over and destroying the prison isolation net. If the vibration is caused by weather or noise factors , no need to deal with, but if the vibration is caused by the prisoner climbing and escaping, i...
