Perimeter security protection system

Abstract

The invention discloses a perimeter security protection system which comprises an invasion signal sensing detection unit and a signal processing unit. The perimeter security protection system is characterized in that the invasion signal sensing detection unit comprises multiple optical fiber sensors distributed around a protection area, the optical fiber sensors are jointly connected on a couplerthrough optical fiber, and a light source and an optical fiber detection device are connected on the coupler; the signal processing unit comprises a signal analysis processing module and used for processing optical fiber signals received from the invasion signal sensing detection unit and judging whether the optical fiber signals belong invasion signals or not. The perimeter security protection system adopts optical fiber sensor technology to detect invasion signals, thereby being capable of timely and efficiently detecting invasion events; the optical fiber sensors have good characteristics being free of electromagnetic interference, thereby being accurate and stable in detecting the invasion events.

Description

technical field [0001] The invention relates to the technical field of security protection, in particular to an efficient, stable and low-cost perimeter security system. Background technique [0002] Due to the increase of social wealth and the increase of the threat of international terrorist activities, perimeter security has been paid more and more attention by people, from military, national defense, finance, technology to social security and other aspects. Although traditional perimeter security systems such as leaking cable systems, active infrared radiation systems, microwave wall systems, and pulse electronic fences can achieve security protection to a certain extent, their technical shortcomings are also obvious, such as high false alarm rates, The intrusion response is not timely enough, the backup of intrusion events is irregular, and the processing of intrusion signals is not systematic. In addition, the intrusion information cannot be retained, and the intrusio...

Problems solved by technology

Although traditional perimeter security systems such as leaking cable systems, active infrared radiation systems, microwave wall systems, and pulse electronic fences can achieve security protection to a certain extent, their technical shortcomings are also obvious, such as high false alarm rates, The intrusion response is not timely enough, the backup of intrusion events is irregular, and the processing of intrusion signals is not systematic, etc.

In addition, the intrusion information cannot be retained, and the intrusion behavior cannot be automatically judged. When encountering the same intrusion information, it is still necessary to manually judge the intrusion method.

Moreover, in the period from the occurrence of the intrusion to the response to the intrusion of the existing technical solutions, it is difficult to capture the intrusion behavior, and it is difficult to guarantee the security, and danger will occur in important places.

In addition, in the existing video technology solutions, the camera has dead angles. Due to the large number of screens in video monitoring, and a huge labor cost is required to implement real-time monitoring, the probability of danger caused by human negligence is also very high.

This makes it impossible for dangerous intrusions to be dealt with in a timely, real-time, and effective manner, and to effectively protect the required protection sites

Furthermore, in the current video surveillance protection scheme, the amount of information and data to be saved is too large, and the cost is relatively high
