Description
Technical field
The present invention relates to a kind of optical fiber alarm rail system and its installation method.
Background technology
Existing boundary's protection system of enclosing generally comprises fence or fence unit and intrusion detection unit, by intrusion detection unit
Whether monitoring peripheral encloses have invader or destruction, and the monitoring element in the intrusion detection unit for using in the past is typically collected and recorded as dress
Put, infrared ray sensor, electronic impulse rope or shock sensor, though simple defense function can be realized, all exist
Drawback, for recording apparatus, video camera there is visual field blind spot, it is necessary to considerable video camera could cover monitor area,
And night, greasy weather video camera cannot normal works, and the environmental suitability of the transmission line of large-scale video camera and video camera itself
It is also a serious problem, although thermal camera can work in night, greasy weather, but its cost is too high, and reliability is farther
It is inferior to ordinary video video camera；For infrared ray sensor, arrangement infrared beams is allowed to delimit the circumference to be monitored, Mei Dangyou
People then causes the temporary transient interruption of infrared beams when passing through the circumference, so as to start alarm signal, the system rate of false alarm is high, plant
Leaf, toy can all cause infrared alarm, not have the function that stop personnel invade, and their monitor area is general not
More than ten meters；It is that the circumference to be monitored delimited using electronic impulse rope for electronic impulse rope, 60 times per minute of electronic impulse
Each wire of scanning electron wall, each peak value of pulse has 5-8 kilovolts, makes invader be difficult to climb up and over, and such system has one
Fixed deterrent effect, but can not repeatedly intrusion detection, it is impossible to positioning invasion position, it is impossible to round-the-clock monitoring；And passed for vibrations
Sensor, it is arranged in mesh sheet or in hollow column, and cable need to be only cut when in mesh sheet can just make its ineffective,
Just lose monitoring function, and be arranged on that alarm on column is insensitive, can regularly cause situation about failing to report.
