Perimeter protection alarm system

Abstract

The invention relates to a perimeter protection alarm system, comprising an alarm situation management center, a plurality of alarm hosts and a plurality of sets of active infrared detectors, whereinthe alarm situation management center and the alarm hosts are connected by a 485 bus; the plurality of sets of active infrared detectors respectively form a plurality of coaxial protective rings withsequentially increasing radiuses, and the protective rings take the center of a protection area as the center; and each protection ring corresponds to one alarm host, and the infrared detectors constituting the protection ring are connected to the alarm host corresponding to the protection ring through a CAN bus. The scheme of the invention utilizes an active infrared detection technology to realize the security protection work in key areas, and the system has the characteristics of mature technology, high reliability, easy expansion, simple operation, good economy and the like. Since the plurality of sets of active infrared detectors respectively form the plurality of coaxial protective rings with sequentially increasing radiuses, the hierarchical protection alarm for the key areas can beachieved, and moreover, through the arrangement of the multi-layer protection ring, the areas where criminals invade can be roughly judged, and the targeted alarm situation handling can be carried out.

Description

technical field [0001] The invention relates to the technical field of security, in particular to a perimeter protection alarm system. Background technique [0002] With the development of society and the improvement of placement awareness, modern security technology has been widely used. In some important areas, such as parks, chemical companies, airports, military bases, weapons and ammunition depots, prisons, bank vaults, museums, etc., in order to prevent illegal intrusion and various damages, traditional protective measures are on the periphery of these areas. Set up some barriers or obstructions, and arrange for personnel to increase patrols. In the current situation that criminals use advanced science and technology, and the means of crime are more complex and intelligent, the traditional means of prevention are difficult to meet the needs of the security work of key departments and key units. Moreover, human prevention is often affected by factors such as time, reg...

Problems solved by technology

In the current situation where criminals use advanced science and technology, and criminal methods are more complex and intelligent, traditional prevention methods are difficult to meet the needs of key departments and key unit security work

Moreover, manpower prevention is often affected by factors such as time, region, personnel quality and energy, so loopholes and mistakes will occur.
