Therefore, in areas where environments are complicated, such as the railway line 6, the railway line 6 near the residential area, and the railway yard, it is necessary to provide a plurality of front-end detecting devices 1 according to the circumstances. Under the cooperation of various front end detection devices 1, the overall safety precaution effect of the railway perimeter safety precaution system is improved.
In the area along the wider railway line 6, the electronic fences 111 are arranged on the two sides of the railway, and the electronic fences 111 can be erected independently or can be hung on the fences or enclosing walls 7 erected on the two sides of the railway. Since the electronic fence 111 is suitable for the precautionary work in a long distance range, it is suitable for the open area section along the railway line 6. Because adopt electronic fence device 11 alone to survey the invasion action, can cause the inaccurate problem in specific position that the invasion action takes place, when taking place the invasion action simultaneously, control center platform 4 also can not in time receive alarm signal, leads to the safety precaution effect relatively poor, consequently, can lay vibration optical cable 121 towards one side of railway line at electronic fence 111, and vibration optical cable 121 can be fixed on electronic fence 111 through the mounting. And a plurality of first camera devices 21 are arranged on the railway line 6, so that the view ranges of the first camera devices 21 do not have blind areas, and all the electronic fences 111 of the railway line 6 can be covered.

The person on duty can confirm whether to report a false alarm. Through the cooperation of above-mentioned fence 111 and vibration optical cable 121, can enough realize the accurate location to the invasion action place, can report to the police moreover, combine first camera device 21, this makes and has obviously promoted in the regional safety precaution effect of 6 along the railway that comparatively open.
In some embodiments, animals may be present from time to time in the area along the railway line 6 near the residential area, which may lead to a situation where the front-end detection device 1 in the area is prone to false alarms. Therefore, a plurality of first audible and visual alarms 31 are required to be arranged in the area of the railway line 6 close to the residential area; when animals or children and the like are on two sides of the railway line 6 and the vibration optical cable 121 outputs an intrusion signal, the person on duty receives the intrusion signal through the control center platform 4, adjusts the first camera device 21 near the occurrence area of the intrusion behavior to the specific position where the intrusion behavior occurs, and checks the intrusion behavior, so that the attack or the intrusion can be judged. At this moment, the accessible starts near first audible and visual alarm 31 and reports to the police to driving animal or child, and then improving the operational environment of railway perimeter, reducing the harassment of personnel and animal etc. and then strengthening safety and protection effect of safety and protection system.

The vibration optical cable 121 is fixedly laid on one side of the electronic fence 111 facing the railway line through a fixing piece. A plurality of rolling cages 8 are arranged on the top of the enclosing wall 7. Meanwhile, at the top of the enclosing wall 7, the emitting end 131 and the receiving end 132 of the laser correlation device 13 may be respectively disposed at two ends of the rolling cage 8, so that the receiving end 132 can receive the infrared ray passing through the middle position of the rolling cage 8. In addition, the second camera device 22 is arranged on the railway line 6, the third camera device 23 is arranged on the top of the electronic fence 111, a blind area cannot exist between the visual field range of the second camera device 22 and the visual field range of the third camera device 23, and all the electronic fences 111 and the enclosing walls 7 of the railway line 6 can be covered.
The intrusion behavior may occur at the place where the electronic fence 111 is installed, and therefore, the description thereof will not be repeated.
When the intruder climbs over the enclosing wall 7, the infrared ray emitted from the emitting end 131 of the laser correlation device 13 is shielded by the intruder and cannot be received by the receiving end 132, and then the intrusion signal is output. At this time, the control center platform 4 can immediately receive the intrusion signal, obtain specific alarm content through processing, and call the second camera 22 or the third camera 23 near the intrusion behavior to adjust to the specific position where the intrusion behavior occurs according to the distance where the alarm occurs, so as to achieve the purpose of visualization. However, when the light is strong, the sensitivity of the laser correlation device 13 is decreased, so that the detection capability of the intrusion behavior is decreased, and the security effect is further decreased. Through setting up the cage 8 that rolls at enclosure 7 top, can increase the degree of difficulty that the invader climbed over enclosure 7, and then reduce the probability that takes place the invasion action in enclosure 7 department effectively to improve the regional safety precaution effect of 6 along this railway.
