Transformer substation fiber perimeter security monitoring system

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...

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 solve perimeter security problems, but due to some objective technical conditions and other factors, there are still some deficiencies, such as: the distance that can be monitored is relatively short, The cost per unit distance is high, and the maintenance cost is high; the chance of interference increases, and the rate of false alarms and false negatives increases; for large-scale monitoring, the lack of positioning function, in case of intrusion behavior, cannot be located, which means that it cannot be determined in a timely and accurate manner. Dangerous locations, unable to take preventive measures in time to prevent intrusions leading to loss of confidentiality and destruction of core areas
