Key area perimeter warning device and method

Abstract

The invention discloses a key area perimeter warning device and method; the device comprises a data acquisition module, a data transmission module, a host computer, an alarm and a power supply module;the data acquisition module is used for gathering a vibration signal; the data transmission module is used for transmitting the vibration signal; the data acquisition module and the data transmissionmodule are buried underground in a topology structure mode so as to form a buried vibration detection transmission network, thus preventing invaders from using equipment to cross the security area, receiving no external influence, generating no harm for men, and improving warning efficiency; the host computer is used for receiving the vibration signal, and determining whether the vibration signalis an invasion signal or not according the vibration signal; if yes, enabling the alarm to send warning and determining invasion target information. The device and method can improve the warning efficiency, can determine the invasion target information, and can prevent invasions, thus truly fundamentally realizing key area warning and anti-invasion functions.

Description

technical field [0001] The invention relates to the field of perimeter early warning and protection, in particular to a device and method for perimeter early warning in a key area of ​​a seismic wave sensor wired local area network. Background technique [0002] The current severe situation of security, horrific jailbreak incidents, frequent warehouse theft incidents, theft incidents of museums and other precious object storage places, and the frequent occurrence of valuable item theft incidents such as bank jewelry stores have brought major hidden dangers to social and public safety. [0003] In order to solve the above major hidden dangers, the following three methods are currently used to realize the early warning of the perimeter of key areas and prevent intrusion: method 1, space area detection; method 2, detection attached to the fence; method 3, independent fence system. However, the first method mainly uses electromagnetic field, infrared, video and other technologie...

AI Technical Summary

Problems solved by technology

However, the first method mainly uses electromagnetic field, infrared, video and other technologies to form an invisible detection area in space, which is seriously affected by external magnetic fields and environmental occlusion, and the use conditions are relatively harsh. In addition, for video surveillance, 24-hour duty is required, and real-time alarms are required. Increase the workload of security personnel; the second method mainly uses electret cables, high-voltage pulse cables, etc. to build a detection system with a certain blocking effect, which is easy to cause personal injury, and can easily cross the security area by drilling holes in the fence and crossing in the air; Method 3 mainly uses sensors such as tension, optical fiber, and high-voltage pulse to build a detection system with blocking and detection functions. This method is prone to false alarms due to thermal expansion and contraction due to temperature changes, and it is easy to use equipment to cross security areas

That is to say, there are many shortcomings in the existing early warning methods for the perimeter of key areas. Generally speaking, there are problems such as intruders are easy to use equipment to cross the security area, vulnerable to external influences, and low early warning efficiency.
