Description
Technical Field
The invention relates to the technical field of access control systems, in particular to an entrance and exit control system and method meeting evacuation requirements.
Background
The entrance and exit control system, commonly known as an entrance guard system, refers to an electronic system that performs operations such as releasing, rejecting, recording, warning and the like on entrance and exit behaviors of a target at an entrance and an exit by controlling the opening and closing of an entrance and exit execution device by using a self-defined coding information recognition and/or mode characteristic information recognition technology. The entrance control system is a component of an electronic protection system in the safety protection system. The entrance control system is provided to achieve "safety" of the entrance. The "safety" of the entrance control system needs to have social and natural attributes. Through system construction, the access has safety protection capability, and is used for preventing, delaying and preventing the occurrence of events such as intrusion, theft, robbery, damage, explosion, violent attack and the like, which is the social attribute (Security) of safety. Meanwhile, the entrance control system must also consider the situations related to personal Safety, such as fire prevention, target injury prevention by non-human factors, etc., and in an emergency situation, people can evacuate rapidly without using certificates, which is a natural attribute of "Safety". When the entrance control system is designed and built, the social property (Security) and the natural property (Safety) of the Safety must be considered, and the principle adopted in most cases is to satisfy the natural property (Safety) of the Safety, namely the Safety evacuation requirement preferentially.
The entrance control system mainly comprises a reading part, a transmission part, a management control part and an execution part, and the logic structure of the entrance control system is shown in figure 1. The system has multiple construction modes, and a reasonable safety protection system needs to be planned according to the aspects of the scale of the system, the actual situation of a site, the safety management requirement of the site and the like during actual design and construction.
The target information is represented as a certificate in the entrance/exit control system. The voucher is a user-defined coded message or pattern characteristic message and/or a carrier thereof, which is unique to the object or object, can be identified, and is used for operating the access control system and obtaining access rights. Common credentials are: PIN, carrier certificate (such as IC card, information button and RFID label), mode characteristic information (such as fingerprint information, face information, palm shape information and iris information), etc.
The identification part mainly uses the identification device to read, identify and output the certificate information to the management control part. The identification device is an electronic device capable of reading, identifying and outputting certificate information, and comprises a code identification device, a biological characteristic identification device, an article characteristic identification device and the like. According to actual needs, when the target leaves from the controlled area, the device can be optionally used for leaving. The request leaving device is used for freely leaving the controlled area, and the exit button is a typical request leaving device.
The management/control part comprises two parts of display/programming and control. The management/control equipment (display/programming part) is positioned in the machine room and the monitoring center, can realize the setting of the access rule and the display of the system state, and is usually represented as a platform and a monitoring station; the management/control apparatus (control section) is generally embodied as an entrance controller capable of processing information transmitted from the recognition device, the departure request device, the entrance sensor, and the like in accordance with a preset rule, and performing control of the entrance by the entrance execution device while recording the relevant information.
The execution part is connected with the entrance controller through the entrance execution device, executes the operation of opening or protecting the entrance, and completes the permission or the rejection of the object to pass through the entrance. The entrance execution device comprises an entrance electronic locking device, such as an electromagnetic lock and a cathode lock.
In order to meet the requirements of safe evacuation at the entrance and exit, the executive device which is opened through power-off operation is generally provided with an emergency evacuation device in the controlled area of the entrance and exit, so as to forcibly open the entrance and exit executive device and realize rapid exit from the controlled area. Emergency evacuation switches are typical emergency evacuation devices.
The application modes of power-on lock and power-off switch and the application modes of power-off lock and power-on switch are two application modes which are most common in the current access control system. An electromagnetic lock (also called a magnetic lock) is usually selected as the entrance and exit execution device in the application mode of power-on lock and power-off lock. By utilizing the 'electromagnetic generation' principle, when the electromagnetic lock is in a power-on state, the strong attraction force generated by the electromagnetic lock when current passes through the silicon steel sheet is generated, so that the locking purpose is achieved; when the electromagnetic lock is powered off, the suction force disappears, and the electromagnetic lock is opened. The "power-off lock, power-on open" application mode access control device is usually selected as a cathode lock (also called an electric padlock). In the power-off state, the cathode lock is locked; when the power is on, the cathode lock acts (the lock catch turns 90 degrees). The cathode lock is arranged on a door frame of the entrance, and the matched latch bolt mechanical lock is required to be arranged on a door leaf of the entrance to realize the opening and closing of the entrance. These two modes have two problems in the application process: firstly, the contradiction between the safety precaution requirement and the safety evacuation requirement; the second is the security problem of the system itself.
A. Contradiction between safety precaution requirement and safety evacuation requirement
Under the application mode of 'power-on lock, power-off switch', in order to meet the requirement of safety evacuation, the electromagnetic lock is switched off, and both sides of the entrance and the exit can freely come in and go out at the moment, so that the safety precaution capacity of the entrance and the exit is reduced. In the application mode of 'power-off lock and power-on opening', the door can be opened in the controlled area by rotating the control handle part of the mechanical lock, and the management control center cannot record the door information and can not meet the control requirement on the entrance and the exit under many conditions.
The two application modes of 'power-on lock and power-off switch' and 'power-off lock and power-on switch' are used for meeting the requirement of safe evacuation, and the safety precaution capacity of the controlled area is reduced. Particularly, in the building entrance and exit, the entrance and exit of an important passageway, the entrance and exit of an important asset storage area, the entrance and exit of an office area, and related units with higher requirements on safety protection, high-level safety protection cannot be realized by only selecting any one of the two schemes.
There are also relevant solutions in the industry for the contradiction between the two, and these solutions can be generally divided into three categories: one is that people are evacuated in emergency by independently arranging an outdoor safe escape passage (such as an escape stair, a rope ladder and the like); the second is to improve the performance of the access door, such as installing an emergency escape device on the access door or improving the structure of the access door, so as to realize safe evacuation of the access; the third type is that the access door is opened in the controlled area by means of technical improvement (such as electromechanical integrated lock, smoke detector installed in the controlled area to realize door opening linkage) and the like. The schemes have certain disadvantages, for example, the outdoor safe escape passage is difficult to meet the escape capacity of partial personnel (children and old people); the method for modifying the entrance and exit and the method for improving the entrance and exit control system through the technical method have the problems of high cost and poor universality.
B. The safety protection capability of the system is insufficient
In the process of system construction, all pipelines are difficult to be intensively distributed in a controlled area, and the pipelines are exposed in an uncontrolled area. If the application mode of 'power-on lock, power-off switch' is used, the forced opening can be realized by destroying the power line of the electromagnetic lock, and the safety protection capability of the entrance is reduced.
In addition, under two application modes of 'power-on lock, power-off switch' and 'power-off lock, power-on switch', except the door leaf hinge, both the door leaf and the door frame have only one locking point, and the problem of insufficient protection strength also exists.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide an entrance and exit control system and method meeting evacuation requirements, which are based on application modes of 'power-on lock, power-off lock', 'power-off lock and power-on lock', fully combine the characteristics of the two application modes, and respectively mount an electromagnetic lock and a cathode lock on an entrance and an exit, thereby providing a scheme for solving the contradiction between the safety precaution requirements of the entrance and the exit and the safety evacuation requirements, not only improving the technical opening prevention capability of the entrance and the exit, but also effectively improving the safety precaution capability of the entrance and the exit on the premise of meeting the safety evacuation requirements.
In order to achieve the purpose, the invention adopts the following technical scheme:

Furthermore, the entrance controller is accessed to the management control center.
Further, the locking device of the power on/off lock comprises a cathode lock.
Further, the power-on lock and power-off lock device comprises an electromagnetic lock.
The invention also provides a method for utilizing the entrance and exit control system conforming to the evacuation requirement, which comprises the following steps:

when the entrance controller receives information of a recognition device or a request for leaving the device, the information is processed, if the information passes an authentication rule, a relay in the entrance controller acts and links a locking device of a power-on lock and a locking device of the power-on lock and the power-off lock to act simultaneously, wherein a normally closed output contact of the locking device connected with the power-on lock and the power-off lock is changed from a connected state to a disconnected state, the locking device connected with the power-on lock and the power-off lock is opened, a normally open output contact of the locking device connected with the power-on lock and the power-off lock is changed from the disconnected state to the connected state, the locking device connected with the power-on lock and the power-off lock is opened, and the entrance is; after the preset release time in the entrance controller, the relay in the entrance controller acts and is linked with the locking device of the power-on lock and the locking device of the power-on lock to act simultaneously, and the entrance controller is restored to the locking state again;
when the door is in an emergency evacuation state, the power supply of the lock is cut off, the locking device of the power-on lock which is powered off is in an open state, the locking device of the power-on lock which is powered off is in a locked state, people in the door need to rotate the control handle part of the mechanical latch with the latch bolt from the door so that the latch bolt of the mechanical latch with the latch bolt retracts to open the entrance, and people outside the door cannot open the entrance.
As a scheme, in an emergency evacuation state, when the connection between an emergency evacuation device and a lock power supply is cut off, the lock power supply is disconnected, at the moment, a locking device which is powered on and off by a power-on lock is in an opening state, the locking device of the power-on and off lock is in a locking state, people in a door need to rotate a control handle part of a mechanical latch of an inclined bolt from the inside of the door to retract a lock bolt of the mechanical latch of the inclined bolt to open an entrance, and people outside the door cannot open the entrance.
As another scheme, in an emergency evacuation state, when a fire protection system is triggered, a lock power supply is disconnected, at the moment, a locking device which is powered on and powered off by an electrified lock is in an open state, the locking device which is powered on and powered off by the electrified lock is in a locked state, people in a door need to rotate a control handle part of a mechanical latch with an inclined bolt from the inside of the door, the lock bolt of the mechanical latch with the inclined bolt retracts to open an entrance, and people outside the door cannot open the entrance.
The invention has the beneficial effects that:
the invention provides a system and a method for solving the contradiction between the security protection capability of an entrance and the security evacuation requirement. The emergency evacuation system has the advantages of two common application modes of power-on lock, power-off unlocking, power-off lock and power-on unlocking while meeting the emergency evacuation requirement, and effectively improves the safety protection capability of the entrance and the exit and the self protection capability of the system.
Specifically, when the system normally works, the access door and the door frame have two locking points, and the protection capability of the access door is superior to that of a common access control system with a single locking point.
When an emergency evacuation requirement exists and the power supply of the lock is disconnected to achieve evacuation, the electromagnetic lock is opened, the cathode lock keeps locked, the access door keeps a locked state, and at the moment, the handle part is controlled to be rotated from the inner side (inside the door) of the latch bolt mechanical lock to open the access door, so that evacuation is achieved. And the fixed handle outside the latch bolt mechanical lock (outside the door) can not make the latch bolt of the latch bolt mechanical lock retract, the access door keeps locked, and personnel outside the access door can not enter the door, so that the access door protection capability in an evacuation state is improved.
The method can effectively prevent lawless persons from trying to enter the door by destroying the lock power supply, and further increases the self protection capability of the entrance and exit control system.
2. The invention has wide application range, can be used for controlling the entrance and exit doors of buildings and the safe evacuation passage doors in daily use, has low implementation cost and high economy, and only needs to add one electronic lock on the prior use mode.
3. The invention has stable performance in practical application, does not need to pass through a complex processing flow in the realization process, does not influence the processing speed of an entrance control system, and has the potential of wide popularization.
