An entrance and exit control system and method meeting evacuation requirements

Abstract

The invention discloses an entrance and exit control system and method that meet evacuation requirements. The system includes a locking device for turning on and off the electric lock, a locking device for turning on and off the electric lock, an entrance and exit controller, a reading device and / or a request to leave device; the locking device for power-on lock and power-off is installed on the door leaf and the door frame, forming a locking point between the door leaf and the door frame; The mechanical lock cooperates to form another locking point of the door leaf and the door frame; the locking device of the power-on lock is connected to the lock power supply through the normally closed output contact of the relay of the entrance and exit controller; the locking device of the power-on and power-off electric lock The normally open output contact of the relay of the entrance / exit controller is connected to the power supply of the lock; the reading device and / or the device for requesting to leave is connected to the entrance / exit controller. The invention can improve the anti-technical opening ability of the entrance and exit, and can effectively improve the safety protection ability under the premise of meeting the requirements of safe evacuation.

Description

technical field [0001] The invention relates to the technical field of access control systems, in particular to an access control system and method meeting evacuation requirements. Background technique [0002] The entrance and exit control system, commonly known as the access control system, refers to the use of custom coded information identification and / or pattern feature information identification technology to control the opening and closing of the entrance and exit execution device, so as to implement the release, rejection, recording and warning of the entry and exit behavior of the target at the entrance and exit. operating electronic systems. The access control system is an integral part of the electronic protection system in the security system. The purpose of setting up the entrance and exit control system is to realize the "safety" of the entrance and exit. The "safety" of the entrance and exit control system needs to have social attributes and natural attribut...

AI Technical Summary

Problems solved by technology

In the application process of these two modes, there have always been two problems: one is the contradiction between the security protection requirements and the security evacuation requirements; the other is the security problem of the system itself

There are certain drawbacks in these several types of schemes, such as the outdoor safe escape passage is more difficult to meet the escape ability of some people (children, old people); poor fit

[0014] B. The security protection capability of the system itself is insufficient

[0015] During the construction of the system, it is difficult to centrally arrange all the pipelines in the controlled area, and there are cases where the pipelines are exposed in the uncontrolled area

If the application mode of "power-on lock, power-off open" is used, the forced opening can be realized by destroying the power cord of the electromagnetic lock, which reduces the safety protection ability of the entrance and exit

[0016] In addition, under the two application modes of "power-on lock, power-off open" and "power-off lock, power-on open", except for the door leaf hinge, the door leaf and the door frame have only one locking point, and there is also the problem of insufficient protection strength
