Problems solved by technology

The traditional security measures are to set up barriers or barriers such as iron fences, walls, and wire fences at the outer perimeter of these areas, and arrange personnel to strengthen patrols. However, criminals are also using advanced science and technology, and criminal methods are more complicated. With modernization and intelligence, the traditional means of prevention have been difficult to adapt to the needs of security work. Moreover, human defense is often affected by factors such as time, region, personnel quality and energy, and it is inevitable that there will be loopholes and mistakes; Radio, video surveillance, microwave radio, electronic fence, power grid, etc., are used to so

Example Embodiment

[0025] Example 1: Vibration sensor optical cable hanging net installation method (installed on the fence)

[0026] The vibration sensor cable 2 adopts the distributed vibration detection sensor cable with patent number 2011201346653 and is laid on the fence (see attached image 3 ), Laying in a straight line: Lay the vibration sensing optical cable 2 at a position about 1.5 meters above the ground from the height of the iron net. Tighten the vibration sensing optical cable 2 with the fence 7 and tie it with a stainless steel cable tie every 50 cm. The binding strength It is advisable that the optical cable is not deformed; the terminal unit 1 and the alarm monitoring unit 3 are respectively fixed on the pillar 8 of the fence, and a separate defense area uses an alarm monitoring unit (collector), and it is believed that the defense area shares a collector.

[0027] In addition to the above linear laying of the vibration sensor optical cable, parallel linear, S-shaped and other forms ...

Example Embodiment

[0039] Example 2: Laying method of vibration sensing optical cable for anti-chipping wall

[0040] Vibration sensing optical cables are laid along the wall. Each vibration sensing optical cable can prevent the upper and lower walls of 50cm. A groove 10 is cut on the wall 9 at a height of 1 meter and 3 meters from the ground. 2 Lay in the groove 10, and fix the vibration sensor optical cable 2 on the wall with clips 6 every 50 cm to prevent people from chipping the wall.

[0041] The vibrating optical cable system is a kind of "tangible" alarm system, which really gives people a sense of deterrence, adds a kind of psychological pressure to the intruder, and can prevent and warn against potential intrusions, thereby combining the alarm system and alert The systems are organically combined to achieve the goal of focusing on prevention and combining prevention and reporting. Used in the perimeter security field, it can achieve pre-deterrence, block and alarm when an incident occurs, a...

Abstract

A transformer substation fiber perimeter security monitoring system disclosed by the present invention comprises a defence area unit and a central control system, the defence area unit is divided into a plurality of defence areas, and each defence area comprises a terminal unit, a vibration sensing optical cable, an alarm monitoring unit and a signal transmission optical cable which are connected orderly. The adjacent defence areas share one alarm monitoring unit, the signal transmission optical cables are connected with the central control system, and the central control system sends the alarm protocol data to the linkage devices via a network or an interface to configure an alarm linkage system. The transformer substation fiber perimeter security monitoring system of the present invention has the advantages of being low in signal detection loss, unit cost and laying cost, wide in monitoring range, good in concealment, high in security and automation degree, having no dead zone and electromagnetic radiation, having passive links, belonging to the active monitoring, etc., is specially suitable for the occasions of higher security levels, such as a transformer station, etc.

Description

technical field [0001] The invention relates to the field of security monitoring, in particular to a security monitoring system for a substation optical fiber perimeter. Background technique [0002] The substation is an important and special place, and its security work is very important. In order to prevent illegal intrusion and various sabotage activities, a security system must be installed around the substation. The traditional security measures are to set up barriers or barriers such as iron fences, walls, and wire fences at the outer perimeter of these areas, and arrange personnel to strengthen patrols. However, criminals are also using advanced science and technology, and criminal methods are more complicated. With modernization and intelligence, the traditional means of prevention have been difficult to adapt to the needs of security work. Moreover, human defense is often affected by factors such as time, region, personnel quality and energy, and it is inevitable th...
