Description

Access control method to improve security

The invention relates to an access control method for improving security, in particular to a method that can control a plurality of door locks to be set to a locked state at the same time and lose the unlocking authority.

There are many door locks on the market that are used to install on doors. This type of door lock has evolved from a traditional mechanical door lock to an electronic lock that cooperates with motors, solenoid valves and electronic parts. Usually this kind of door lock can be independently controlled to lock or Unlock, so when the door is in the closed position, operating the door lock to lock the door can prevent the door from moving from the closed position to the open position, thereby achieving the effect of anti-theft.

When this kind of traditional door lock is used in a unit with many rooms, it is difficult to ensure that the door lock can be locked to prevent entry at night when there is no one. For example, a school unit has a few classrooms, and each classroom has an independent door. As well as door locks, it is difficult for the school to manage the door locks of each classroom to be locked after class. Therefore, when a campus security incident occurs, the door locks of each classroom cannot be locked immediately to prevent criminals from entering. It is not possible to notify the police system to report the case in the first time, or a large company may have many offices inside, and each office will also have independent doors and door locks. It is difficult for the company to manage the door locks of each office in a unified manner during off hours. It is necessary to lock, but it is very difficult to send personnel to patrol each room to check whether the lock is actually locked, regardless of whether it is a school or a large company. In addition, when a fire occurs, it is impossible to close the corresponding door in time to respond to the fire, or it occurs. During shooting incidents (such as campus shootings), it is also impossible to control the delay of access control or prevent the intrusion of criminals in time.

In order to solve the problem that the known access control method cannot effectively manage multiple door locks at the same time or individually, and cannot manage and control the access control in time when a fire or shooting event occurs, the present invention provides an access control method with improved security, including connection , Connect a plurality of door locks with a control device, make the control device obtain the control authority of each door lock, whether the emergency control unit is connected, check whether an emergency control unit is physically removably connected to the control device, and obtain the operation authority In the case that the emergency control unit is not physically and removably connected to the control device, all door locks obtain the authority to independently operate the locking or unlocking, and identify the emergency control unit. When the emergency control unit and the control device are physically connected In the case of removably connected, identify whether the emergency control unit is successful or not. If the emergency control unit fails to identify, enter to obtain the operation authority so that all door locks obtain the authority to independently operate the lock or unlock. The first priority emergency state is When the emergency control unit physically removably connected to the control device is successfully identified, all the door locks connected to the control device are set to the locked state at the same time, and an alarm is generated. When all the door locks are set to the locked state at the same time, an alarm is generated. Let people know that an emergency occurs and the unlocking authority is lost. If the emergency control unit is successfully identified, all the door locks set to the locked state lose the unlocking authority and cannot be unlocked by independent operations. Whether the emergency control unit is removed, detect the emergency Whether the control unit is physically separated from the control device, keep the unlocking authority lost, keep the emergency control unit physically and removably connected to the control device, keep all the door locks without the unlocking authority, log in to the background, in the emergency control unit When physically separated from the control device, use a computer or a smart mobile device to log in to the background with a preset account and password to connect to the control device. Whether to cancel the first priority emergency status, after logging in to the background interface, the administrator can choose to cancel Or do not lift the first priority emergency state, keep losing the unlocking right Limited, if the first priority emergency state is not lifted in the background login, all the door locks set to the locked state will lose the unlocking authority, and the unlocking authority will be restored. After logging in to the background and the control device and the emergency control unit are physically separated If the first priority emergency state is lifted, all the door locks set to the locked state will return to the independent operation locking or unlocking authority, and the gunshot control state will detect whether a gunshot occurs when all the door locks obtain the independent operation locking or unlocking authority. In the event, if a shooting incident is not detected, each door lock maintains the unlocking authority and reports the shooting position. When a shooting incident is detected, the location of the shooting incident is returned to the control device, the shooting is notified, and the control device receives the occurrence The information on the location of the shooting incident will be sent to the alarm system at the same time. The door locks in the vicinity of the shooting are set to the locked state, and at least one door lock adjacent to the place where the shooting occurred is set to the locked state and the unlocking authority is lost. If the shooting control state is not released, at least one door lock that has lost the unlocking authority due to the shooting event will keep losing the unlocking authority. If the shooting control state is to be released, the emergency control unit and the connector are allowed to log in to the background selection The gunshot control state is released, and the unlocking authority is restored. After the gunshot control state is released, the at least one door lock that is set to the locked state due to the shooting event restores the unlocking authority, and the at least one door lock obtains the independent locking and unlocking authority.

The security-enhancing access control method of the present invention provides gunshot detection and control, can quickly detect the location of the gunshot and quickly control the door lock adjacent to the gunshot to be set to the locked state and lose the unlocking authority through the control device. The effect of delaying or preventing the movement of the person who initiated the shooting.

The security-improved access control control method further includes: the first level notification, after all door locks lose the unlocking authority, the alarm system is communicated to generate an alarm, and the control device receives the transmission An alarm message is generated at the same time as the information of the place where the shooting event occurred, and the alarm is cancelled. When the shooting control state is released, the control device stops generating the alarm message.

The security-improved access control method further includes: setting a second priority emergency state, allowing the setting of the second priority emergency state when the control device is physically connected to the unlocking device and logged into the background. In the priority emergency state, all door locks maintain their respective unlocking authority. If the second priority emergency state is set, all the door locks are set to the locked state and the unlocking authority is lost. The second level notification is set when the second priority emergency state is set and all door locks are After setting to the locked state, through the alarm system, whether to cancel the second priority emergency state, log in to the background when the unlocking device is connected to the control device, you can choose to cancel the second priority emergency state, if the second priority emergency state is released, all doors will be locked All door locks will lose the unlocking authority if the second priority emergency state is not lifted.

The control device 33 is paired with the emergency control unit 40A. The emergency control unit 40A of the present invention preferably uses an access card. The emergency control unit 40A is used to control the control device 33. The emergency control unit 40A stores corresponding control identification information. All the memory 29 of the plurality of door locks 20 internally stores a comparison identification information corresponding to the control identification information possessed by the paired emergency control unit 40A, and the emergency state identification information is stored in the remote controller 60, so When the remote controller 60 is used to operate the door lock 20 in the locked state, the door lock 20 receives the emergency status identification information transmitted by the remote controller 60 and compares it with the internal identification information of its own memory 29. If the door lock 20 compares The emergency status identification information transmitted from the remote controller 60 is correct, and the door lock 20 that receives the emergency status identification information sent by the remote controller 60 will be set to a locked state and lose the unlocking authority.

The security-enhancing access control method of the present invention is implemented by the central access control system 10. Assuming that each door is closed and the latch head 23 is in the latched position, the first connection is connection S101, which connects a plurality of door locks 20 with a control device 33 The control device 33 obtains the control authority of each door lock 20. In essence, the control device 33 obtains the control right of the electric setting device 30 of each door lock 20. Further, the control device 33 can control a specific one at the same time. The locking mechanisms 24 of a plurality or all of the door locks 20 are set to a locked state or an unlocked state.

Whether the emergency control unit is connected to S103A, check whether an emergency control unit 40A is physically and removably connected to the control device 33. The physical removably connection means that the card-type emergency control unit 40A is a card inserted It is electrically connected to the connector 38 of the control device 33 so that the control device 33 can read the control identification information in the emergency control unit 40A.

Obtain the operation authority S108A. In the case that the emergency control unit 40A is not physically and removably connected to the control device 33, all the door locks 20 obtain the respective independent operation of the locking or unlocking authority. Specifically, in the emergency control When the unit 40A is not physically connected to the connector 33 of the control device 33, the control device 33 will not drive any of the door locks 20. The electric setting device 30 sets the locking mechanism 24 to the locked state, so each door lock 20 The locking mechanism 24 will maintain the original state, and the respective door locks 20 are allowed to be used by the first or second manual setting device 26, 27 to independently set the locking mechanism 24 to the locked or unlocked state, and set to the unlocked state The door lock 20 allows the use of the first or second handle 34A, 341B to operate the latch driving device 22 in conjunction with the latch head 23 to retract to the unlatched position.

Identify the emergency control unit S104A. When the emergency control unit 40A and the control device 33 are physically and removably connected, identify whether the emergency control unit 104A is successful. If the emergency control unit 40A fails to identify, enter to obtain the operation authority S108A. The departmental lock 20 obtains the authority to independently operate the locking or unlocking.

The first priority emergency state S105, when the emergency control unit 40 physically and removably connected to the control device 33 is successfully identified, all the door locks 20 connected to the control device 33 are set to the locked state and locked at the same time. Specifically, after the control identification information of the emergency control unit 40A is correctly identified, the control device 33 enters the first priority emergency state S105, and In addition, the control device 33 drives the electric setting device 30 of all the door locks 20 to set the locking mechanism 24 to the locked state, so that all the door locks 20 lose the unlocking authority S109. In this case, each door cannot be operated by the key first or second The second manual setting device 26, 27 sets the locking mechanism 24 to the unlocked state, so that the door cannot be opened through the first handle 34A, that is, the emergency control unit 40A is physically connected to the connector 38 of the control device 33 and the identification is confirmed In this case, all the locked door locks 20 lose the unlocking authority S109 and cannot be independently operated into the unlocked state, further achieving the control function that all the doors cannot be easily opened from the outside, but even if all the door locks 20 lose the unlocking authority S109 , It is still allowed to use the second handle 34B from the inside of the door to operate the latch head 23 of the door lock 20 to move to the unlatched position to open the door. In addition, after entering the first priority emergency state S105, the prompting devices 32 of all door locks 20 issue an emergency Warning signal.

An alarm S110 is generated. When the first priority emergency state S105 is entered, the control module 33A of the control device 33 drives the alarm 62 to generate a sound or light or sound and light alarm message.

The first level notification S111, after all the door locks 20 lose the unlocking authority, the alarm system is communicated, that is, when the emergency control unit 40A and the connector 38 of the control device 33 are physically connected and all the door locks 20 lose unlocking At the same time as the authority, the control device 33 drives the safety notification device 54 to automatically notify the police system (reporting) that an emergency occurs (for example, a gangster breaks into the campus).

Whether the emergency control unit is removed S113A, it is detected whether the emergency control unit 40A is physically separated from the control device 33.

Keep losing the unlocking authority S115A. When the emergency control unit 40A is physically and removably connected to the control device 33, all the door locks 20 that are set to the locked state lose the unlocking authority. Specifically, all the door locks 20 In the emergency state where the unlocking authority is lost, if the emergency control unit 40A is still physically connected to the connector 38 of the control device 33, all the door locks 20 are still locked and the unlocking authority remains lost.

Log in to the background S117. When the emergency control unit 40A is physically separated from the connector 38 of the control device 33, use a computer 52 or a smart mobile device 50 to log in to the background to connect to the control device 33 with a preset account and password. After logging in to the background, the computer 52 or smart mobile device 50 can determine whether to release the first priority emergency state S119. That is to say, after logging in to the background interface, the administrator can choose to release or not release the first priority emergency status. If the first priority emergency state is not released, all the door locks 20 that are set to the locked state will keep losing the unlocking authority S131. If the connector 38 of the control device 33 is physically separated from the emergency control unit 40A after logging in to the background, if The first priority emergency state is released, and all the door locks 20 that are set to the locked state are restored to the independent operation to lock or unlock the restoration and unlocking authority S133, and when the restoration and unlocking authority is set to S133, the alarm cancellation S135 is also executed, so that the control module 33A The alarm 62 is controlled to stop operating, and the reminding device 32 of each door lock 20 is controlled to stop operating.

It should be noted that after entering the first priority emergency state S105, even if the emergency situation is eliminated and the connector 38 of the control device 33 is physically separated from the emergency control unit 40A, all the door locks 20 will not obtain the unlocking authority. Must be correctly identified by the emergency control unit 40A and the manager logs into the background and operates to release the first priority emergency state, all door locks Only 20 can obtain the unlocking authority. Each door lock 20 can set the locking mechanism 24 to the unlocked state or locked state through the first or second manual setting device 26, 27. This method can effectively prevent criminals from turning the emergency control unit 40A. The first priority cancellation state is physically separated from the connector 38 of the control device 33.

It is worth mentioning that the restoration of the unlocking authority can also be set to restore the state of each door lock 20 before entering the first priority emergency state. For example, a part of all the door locks 20 before entering the first priority emergency state. Each is independently set to be locked, and the other part of the door locks 20 are independently set to be unlocked. After the first priority emergency state is released, the part of the door locks 20 that are set to be locked remain locked but can be independently locked. The operation is unlocking, and the door lock 20 that was set to be unlocked before entering the first priority emergency state returns to unlock after the first priority emergency state is released and can be independently operated to be locked.

Set the second priority emergency state S201. When the control device 33 is physically separated from the emergency control unit 40A and logged into the background, the second priority emergency state is allowed to be set. If the second priority emergency state is not set, all door locks 20 will be individually Maintain the unlock authority S203. If the second priority emergency state is set, all door locks will be set to the locked state S205 and the unlock authority will be lost. In detail, the emergency control unit 40A and the connector 38 of the management device 33 are physically separated and through the computer 52 or after the smart mobile device 50 logs in to the background, the administrator can choose whether to set the second priority emergency state S201 on the background interface. For example, when a gangster invades the campus and the administrator is located far away from the control device 33, When the emergency control unit 40A and the control device 33 are physically combined in time, the administrator can use the smart mobile device 50 to log in to the background, and further select and press the icon for setting the second priority emergency state, so that the control device 3 3 When the emergency control unit 40A is physically separated, the locking mechanism 24 that controls all the door locks 20 is set to the locked state, so that all the door locks 20 lose the unlocking authority. In this state, all the door locks 20 cannot be used. The first handle 34A operates the bolt head 23 to move to the unlatched position, but the second handle 34B is allowed to operate, and each door lock 20 cannot be independently set to unlock. When the second priority emergency state is entered, the prompt devices 32 of all the door locks 20 Issue an emergency warning signal.

While entering the second priority emergency state, the control device 33 executes the second level notification S206. After the second priority emergency state is set and all door locks 20 are set to the locked state, the alarm system is communicated.
