The camera is arranged at the position of the boundary of the detecting protection area, the camera is connected to the intelligent video monitoring unit, the detecting optical cables are arranged in the detecting protection area in a distribution mode, and the detecting optical cables are connected to the distribution type optical fiber invasion alarm unit in the monitoring room. The distribution type optical fiber invasion alarm unit and the intelligent video monitoring unit are respectively connected to the system integration platform.

Description

technical field [0001] The invention relates to the technical field of safety monitoring, in particular to a real-time safety monitoring system based on a distributed optical fiber intrusion alarm unit. Background technique [0002] With the continuous progress of society, rapid economic development and rapid technological advancement, people pay more and more attention to public order safety, production safety and property safety, and safety monitoring systems are widely used in various industries. [0003] At present, there are more and more types of monitoring systems on the market. Distributed optical fiber sensing technology is a sensing measurement method that can best reflect the advantages of optical fiber distribution and stretching. Distributed optical fiber intrusion alarm units are often used to achieve security monitoring. The most notable advantage of the distributed optical fiber intrusion alarm unit is that it does not need to form a loop, only one optical f...

AI Technical Summary

Problems solved by technology

Due to the existence of external irrelevant factors such as wind and rain, although it can be identified through relevant algorithms or adjusting thresholds, there are still uncertainties, which will increase the false alarm rate and false alarm rate of the system and reduce the reliability of the system.

[0004] When the video surveillance system is used to monitor a large-scale protection area, multiple cameras need to be connected to cover the entire area, which greatly increases the cost of the monitoring system; in addition, people or vehicles passing through the fence of the protection area are not in the protection area, but Entering the warning area of ​​the monitoring system will also cause the alarm of the video monitoring system, increasing the false alarm rate
