As an important subsystem of the security system, the Australian Access Control System has the characteristics of active prevention, and cooperates with various hardware electric locks to reject illegal intrusions. Two-door interlocking and guarding against tailgating are featured features of the access control system, enabling more secure and reliable access control management.
At present, manufacturers of access control systems have begun to produce double-door interlocks and anti-trailing products. It is mainly used in places with high security performance such as banking, telecommunications and postal services. Two-door interlocking and guarding against tailgating products are overall considerations for the lock and controller (ie, access control). In general, simply relying on the access control system cannot achieve the functional requirements of the two-door interlocking product. In the following, the author elaborates on how to implement double-door interlock and anti-trailing function in the access control system, and discusses with the industry peers.
Aopu's two-door interlocking function for interlocking means that the two doors have the function of interlocking and interlocking. That is, when one door is opened, the other door will not open. Only when both doors are closed, can they be opened. Any door. And each pass through a door must be locked before it can enter the latter door. If the door is not locked after entering the first door, it will not enter the second door. When entering each door, it must pass identity authentication. The identity recognition device can use a card reader, and can also use biometric devices such as a fingerprint reader and a HandReader.
The access control function of the Aopu gate is the opening of the control door. The opening of the door is controlled by the on/off of the electronically controlled lock. The electronically controlled lock acts as a front-end execution device and is controlled by the access control device. Therefore, the door is controlled. The time can be opened, in the final analysis, is to control when the access control device can receive, process valid authentication information or exit request from the identification device or the exit button.
Take the example of entering a safe area from a public area. When the palm shape is verified by HandReader 1,
The door 1 is in an open state. At this time, the HandReader 2 and the exit button 2 need to be shielded to make them in a non-use state. That is, at this time, the hand-shaped authentication of the HandReader 2 or the pressing of the exit button 2 cannot trigger the electricity. The lock 2 is opened so that the door 2 is opened. Only when the door 1 is closed and the electric lock 1 is powered on, the hand reader 2 and the exit button 2 are activated again, and they are in the enabled state, and the operation request of the Hand Reader 2 or the exit button 2 can be accessed. Similarly, when the palm shape is validated by the HandReader 2, the door 2 is in an open state. At this time, the HandReader 1 and the exit button 1 should be shielded to ensure that the door 1 cannot be opened. Only when the door 2 is closed and the electric lock 2 is powered on, the HandReader 1 and the exit button 1 can be activated again.
The key to the realization of the Australian gate access dual-door interlock function is when the access control system detects when any signals are masked/activated, ie define a mask point and an activation point. The above valid tapping or exit button signals are mask points. The door is closed and the electric lock power is the activation point. As long as the two points of the shielding (non-enable) and the activation (enable) are controlled, the two-door interlocking and the multiple-door interlocking can be realized. Device shielding, activation, and event linkage are all set through the access control management software and then downloaded to the access controller. The system can still operate in the offline state.
There are two ways to realize the Australian Gate Access Control System with two-door interlock function. One is a special controller designed and produced specifically for this function; the other is implemented through the access control management software. The latter, through software settings, can achieve dual-door interlocking in different areas, and can be arbitrarily set for dual-door interlocking, or even multiple-door interlocking, with convenient system management and greater scalability. Anti-trailing function The anti-trailing function refers to the function of preventing unauthorized persons from using the time when the legal card holder enters the controlled area and the electronically controlled door lock is not closed. For the case of opening the door at one time and entering multiple people, the inclusion of the duress alarm function is beyond the scope of this article. In the access control system, the anti-trailing function can be guaranteed and implemented in a variety of ways.
1, in the Australian access control ban controller side, through the automatic relock function, control the lock time of the electric lock, to achieve anti-trailing function. The unlocking time refers to the duration of triggering the lock control relay after the access control device receives the door opening signal, so that the electric lock is in the open state (the door is in the open state). If the unlocking time is set too long, there may be a phenomenon that a person with no permission follows. If the setting is too short, a person with permission may fail to pass through the door opening time due to other reasons, and the door may not pass. Automatically locked.
The Australian Access Control System provides an automatic relock function, which makes a choice between setting the unlocking time and the door closing state, and achieves automatic relocking. For example, if the unlocking time is set to 10 seconds, the lock control relay will be triggered from the valid authority card holder, the electric lock will be in the unlocked state, the card holder will enter the door and the door will be closed. It will take 6 seconds and the access controller will receive the door closing signal. Immediately reset the lock control relay and the electric lock is locked without waiting for 4 seconds. In this way, the possibility of being followed by an unauthorized person after the effective card holder enters the door and before the end of the setting of the unlocking time is eliminated.
2, through the lock alarm function to be achieved. Push bar lock, also called escape device, is mainly used in fire protection, conference rooms and other passages to ensure personal safety and high flow of people. Based on the mechanical push bar lock device, it increases the interface with the access control device and effectively authenticates users. After that, the push bar lock alarm function can be shielded to allow access to the controlled area. When an unauthorized person attempts to follow and go in and out, pushing the push bar to lock the pressure bar, the push bar lock will produce an alarm sound, and at the same time send the alarm signal to the access control system, causing the monitoring center to pay attention.
3. Through the area number calculation function of the access control system, with the directional infrared detection device, accurately count the number of effective card holders entering the area. The access control system increases the number of people in the current region after each area is effectively entered. After an effective exit, the number of personnel is reduced. We call this the number of people in the access control area. Directional infrared detection devices are installed on both the entry door and the exit side. The output signal of the infrared detection device is used as the input signal of the access controller. Every time someone passes, the infrared detection device will generate a signal to the access control system, according to the door entrance or The detector on the outbound side increases or decreases the number of people in the area. We call this the number of infrared detections. When the number of infrared detections is greater than the number of people in the access control area, it can be regarded as people with unauthorized access. In this way, it is advisable to access different ports and improve the accuracy of the infrared detection device from the installation location and the use environment, and require the computer to manage in real time.
The key to the realization of the anti-trailing function is that the electronic control door lock can be closed immediately after the legal person enters, so that the criminals do not have any chance. Therefore, using the automatic relocking function of the access control system is a good solution, and the lock alarm and area number calculation can be used as auxiliary means. Anti-trailing is a very practical function, as long as the design and selection of full consideration, the basic access control equipment configuration, it can be a good implementation of strict access control. Future Development Trends At present, the Australian Gate Access Double Door Interlocking and anti-trailing functions are often used in places such as the cash office of the Banking Agency, bank vaults, and prisons where security requirements are high, and provide security for personnel. With the continuous development of technology, the features of the access control system will be developed in the direction of intelligence, networking, and more flexible and practical.
Its main development direction has the following three points:
1. Enhance the logic judgment ability of the access controller itself. The stronger the logic judgment ability of the access controller, the more powerful management functions can be realized, thereby reducing the dependence on external input signals and management computers.
2. Biometric devices replace readers to improve the reliability of identity authentication and reduce the risk of card loss. In addition, biometrics can provide better support for duress alerts that are closely related to two-door interlocking and anti-trailing.
3, combined with IVS intelligent video system. For example, the area number calculation function of the access control system is compared with the statistics of the area number calculation function of the IVS intelligent video system. When the two do not match, an alarm message is generated.
Conclusion: Implementing anti-trailing and double-door interlocking functions in access control systems is technically not a problem. As the bank's security performance has improved, Austrade's two-door interlock has begun to integrate new technologies, such as high-end biometric technologies such as fingerprints, palms, and irises.
However, in order to achieve real anti-trailing, this article elaborates on the three aspects of the Aussie Gate Access Control System's automatic relocking function to solve the anti-trailing strategy. Locking alarms and calculating regional numbers are auxiliary measures. At the same time, it also introduced its development trend and played a guiding role in the improvement of the two-door interlocking technology.
