    According to the customer's description, it is necessary to provide a set of perimeter alarm system for the perimeter fence of high-speed railway. The system is required to be able to prevent the illegal invasion of the outside world 24 hours a day and provide a safe and harmonious environment. The customer requests that once an illegal group attempts to intrude, the detection unit laid on the media can sense the intrusion signal immediately. And timely transmit the intrusion signal to the alarm host in the machine room, and turn it into the alarm signal after the analysis and processing of the alarm host. The alarm host can output switching signal to the user's hard disk video recorder to realize on-site video linkage.

    The unilateral length of the perimeter fence to be protected this time is about 27km. Because the optical cable is used as the sensing and detecting unit in this scheme, because of its unique linear structure, the optical cable can not be limited by the perimeter contour. When it is used in many circumferences with corner, drop and radian, the optical cable can be laid along with the shape of the perimeter without any dead angle. The vibration optical cable perimeter alarm system does not need to lay power line and signal line, and the service life of the optical cable is long. Therefore, it can meet the requirements of low investment, low energy consumption and high prevention of customers.

    The unilateral length of the defense zone is 27km, and the guardrail is equipped with rolling net mode. The warning areas are divided on the roll net, each of which is 200m long, with a total of 216 defense areas. Build a three-dimensional early warning system.
