Power plant fiber perimeter monitoring system is mainly composed of distributed perimeter monitoring host and detection cable.Fiber optic perimeter prevention monitoring main body mainly through the laying of a fiber optic cable on the fence, to achieve the fence through and prevent overturning the monitoring effect.When there is an intrusion through the fence or over the fence, the fiber optic cable on the fence will be deformed, so the system can immediately locate the alarm, at the same time, the video camera can carry out intelligent automatic capture of the intrusion picture, monitoring background can see the invasion picture in the first time.The system can also link the functions of sound and light alarm, video alarm and short message alarm. The system can send alarm information to the operator's mobile phone to truly realize "unmanned" intelligent monitoring

1. Location alarm is given to the crossing event of breaking Seine net and cutting seine net 

2. Location alarm for jumping over fence 

3. Can link sound and light, video, short message and so on

The cable consumption is 5.5 times of the physical distance. The total cable consumption is (5km-11*0.007-0.0092) *5.5=27Km. Considering the cable distance from the main machine to the site fence and the redundancy of site laying, the total cable

The cable consumption is 4.5 times of the physical distance, and the total cable consumption is (5km-11*0.007-0.0092) Km*4.5=22Km. Considering the cable distance from one main machine to the site fence and the redundancy of site laying, the total cable consumption is 25Km. Cable installed at the top of the fence, cable fixed position 25 cm higher than the highest point of the fence and the cable goes in circles about 50 centimeters in diameter
