Anti-interference optical fiber perimeter protection system and method

Abstract

The invention provides an anti-interference optical fiber perimeter protection system and a method. The optical fiber perimeter protection system comprises a sensing optical cable arranged on a physical perimeter; an acquisition device arranged on the physical perimeter and used for acquiring signals transmitted by the sensing optical cable and sending the signals to a processing and alarm device; and a processing and alarm device arranged on the physical perimeter and used for processing the signals transmitted by the acquisition device and prompting to give alarms according to the requirement. The system and the method are advantageous in that the anti-interference capability is high.

Description

technical field [0001] The invention relates to optical fiber perimeter protection, in particular to an optical fiber perimeter protection system and method capable of resisting wind and rain interference. Background technique [0002] With the continuous development of my country's economy and science and technology, people's awareness of safety precautions is getting stronger and stronger, and the safety precautions of living and living around schools, residential quarters, and industrial parks have become more and more concerned about people. Not only that, the perimeter security of complex environments such as oil fields, oil depots, power plants, and airports deserves special attention. Higher requirements are also put forward for the security of important areas related to national security, such as military sites, judicial prisons, and government agencies. Therefore, A safe and effective perimeter security monitoring system is particularly important. [0003] The trad...

AI Technical Summary

Problems solved by technology

In non-bad weather conditions and uncomplicated environmental conditions, intrusion actions can be accurately determined. However, in harsh environments and more interference conditions, it is difficult to accurately identify human intrusions.

Especially in strong wind and rain, the signal generated by the vibration of the optical cable due to strong wind and rain is similar in strength and frequency to the signal generated by some man-made intrusion actions, so many false alarms will occur

To ensure that false alarms do not occur when it rains, some human intrusions cannot be judged as intrusions by the system under normal weather conditions.
