Device and system used for railway surrounding safety protection

Abstract

The invention proposes a device and a system used for railway surrounding safety protection, wherein the device comprises the following elements connected in succession: a laser emission component, an optical coupling component and a fiber detection module as well as a photoelectric detector in connection with the optical coupling component. Through the arrangement of a fiber detection module in a to-be-monitored protection area and under the condition that the laser beams emitted from the laser emission component pass through the optical coupling component and are transmitted to the fiber detection module where the fiber detection module divides the laser beams into a plurality of incident light and outputs the interfering light formed among the reflection light corresponding to the incident light, when foreign invasion exists, the characteristics of the interfering light outputted from the fiber detection module change with the result that a main controller automatically determines whether the characteristics of the interfering light changes or not so as to determine if there is any foreign invasion to the protection area. Therefore, the regular inspection of the working people can be eliminated, thus reducing the manual cost considerably, increasing the detection efficiency and at the same time, ensuring the timeliness of the monitoring result.

Description

technical field [0001] The invention relates to the technical field of railway perimeter safety protection, in particular, to a device and system for railway perimeter safety protection. Background technique [0002] At present, in the process of railway perimeter security protection, the monitoring of railway perimeter security protection is mainly carried out in the following two ways. One way is: arrange special staff to regularly go to the site of the railway perimeter protection zone to inspect whether there is any external intrusion Another way is: install a plurality of camera devices in the perimeter protection zone of the railway to be monitored, collect the video information in the protection zone through the camera devices, and then analyze the video information by special staff to determine the railway Whether there is external intrusion in the protection zone on both sides. [0003] In the process of realizing the present invention, the inventors have found tha...
