Abstract

A method for controlling door access with improved safety includes connecting door locks with a control device. Through physical and electrical connection by an emergency control unit, the control device can set all door locks to a locking state and can revoke unlocking authority of all door locks. When the emergency control unit is physically disconnected from the control device, all door locks can operate independently in locking and unlocking. Furthermore, the control device is connected to a plurality of gunshot detection devices and/or a plurality of fire detection devices. When a gunshot event and/or a fire occurs, the door locks near the gunshot location or the fire can be rapidly locked to reduce the movement speed of the gunman and/or the spreading speed of the fire.

Description

Access control method to improve security

The present 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 make them 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 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 are no people. For example, there are a few classrooms in a school unit, and each classroom has an independent door. As well as the 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 gangsters 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 also difficult for the company to manage the door locks of each office in a unified manner during off-hours. It must be locked. However, 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 for the fire, or it occurs. When shooting incidents (such as school 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 methods cannot effectively manage multiple door locks at the same time or individually, and cannot manage 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 connecting, 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 locking or unlocking. The first priority emergency state, when When the emergency control unit physically and 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, and be 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 state, after logging in to the background interface, the administrator can choose to cancel Or do not cancel the first priority emergency state and keep the unlocking authority lost. If you do not cancel the first priority emergency state in the login background, all the door locks set to the locked state will keep losing the unlocking authority, and the unlocking authority will be restored. After logging in to the background, the unlocking authority will be restored. When the device is physically separated from the emergency control unit, if the first priority emergency state is cancelled, all the door locks set to the locked state will resume independent operation. The locking or unlocking authority will be restored, and the gun control state will obtain independent operation in all the door locks. Detect whether a shooting event occurs when the permission is locked or unlocked. If a shooting event is not detected, each door lock maintains the unlock permission and reports the shooting position. When a shooting event is detected, the location of the shooting event is returned. To the control device, the shooting notification, the control device receives the information on the location of the shooting incident and simultaneously communicates with the alarm system, the door lock of the vicinity of the shooting is set to the locked state, and at least one door lock adjacent to the location of the shooting incident is set to the locked state And make it lose the unlocking authority and cancel the gunshot control state. If the gunshot control state is not cancelled, at least one door lock that loses the unlocking authority due to the shooting event will remain without the unlocking authority. If the gunshot control state is to be released, it is tight. When the emergency control unit is physically separated from the connector, it is allowed to log in to the background to choose to cancel the shooting control state and restore the unlocking authority. After the shooting control state is released, the at least one door that is set to the locked state due to the shooting event The lock 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-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 S101, which connects the 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 mechanism 24 of multiple or all door locks 20 is set to a locked state or an unlocked state.

Whether the emergency control unit is connected to the S103A, check whether an emergency control unit 40A is physically and removably connected to the control device 33. The physical removable connection means that the card-type emergency control unit 40A is a plug-in card The method 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, all door locks 20 obtain independent operation of the locking or unlocking authority. In detail, in the emergency control unit When 40A is not physically connected to the connector 38 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. Therefore, each door lock 20 is locked. The locking mechanism 24 will remain in its original state, and the respective door locks 20 are allowed to be used with the first or second manual setting device 26, 27 to independently set the locking mechanism 24 to the locked or unlocked state, and is set to the unlocked state. The door lock 20 allows the use of the first or second handle 34A, 34B 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 is physically and removably connected to the control device, identify whether the emergency control unit 40A is successful or not. If the emergency control unit 40A fails to recognize the emergency control unit 40A, enter to obtain the operation authority S108A. The department lock 20 obtains the right to independently operate the lock or unlock.

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. In detail, when the control identification information of the emergency control unit 40A is correctly identified, the control device 33 will enter the first priority emergency state S105, and the control device 33 will drive all the door locks 20 and the electric setting device 30 will lock the mechanism 24. Set to the locked state, so that all door locks 20 lose the unlocking authority S109. In this case, each door cannot be operated by the key to operate the first or second manual setting device 26, 27. The locking mechanism 24 is set to the unlocked state, so the door cannot be unlocked. Open through the first handle 34A, that is, when the emergency control unit 40A and the connector 38 of the control device 33 are physically connected and the identification is confirmed, all the locked door locks 20 lose the unlocking authority S109 and cannot be operated independently In order to unlock, further achieve the control function that all the doors cannot be easily opened from the outside. However, even if all the door locks 20 lose the unlocking authority S109, the second handle 34B is still allowed to operate the latch of the door lock 20 from the inside of the door. 23 is moved to the unlatched position to open the door. In addition, after entering the first priority emergency state S105, the prompt device 32 of all door locks 20 will issue an emergency warning signal.

An alarm S110 is generated. When entering the first priority emergency state S105, 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 is physically connected to the connector 38 of the control device 33 and all the door locks 20 are lost and unlocked At the same time, the control device 33 drives the safety notification device 54 to automatically notify the police system (reporting) of an emergency (such as a gangster breaking into a campus).

Whether the emergency control unit removes S113A, and detect whether the emergency control unit 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. In detail, in 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 backend 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 backend to connect to the control device 33 with a preset account and password. After logging in to the background, you can use the computer 52 or smart mobile device 50 to decide 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 lose 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, all the door locks set to the locked state are restored to the independent operation to lock or unlock the recovery unlock authority S133, and when the recovery unlock authority S133 is set, the alarm cancellation S135 is also executed, so that the control module 33A Control the alarm 62 to stop operating, and control the respective reminder device 32 of each door lock 20 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. When the emergency control unit 40A is correctly identified and the administrator logs in to the background and operates to release the first priority emergency state, all door locks 20 can obtain the unlocking authority, and each door lock 20 can be set individually through the first or second manual The devices 26 and 27 set the locking mechanism 24 to the unlocked state or the locked state. This method can effectively prevent criminals from physically separating the emergency control unit 40A from the connector 38 of the control device 33. The first priority is to cancel the emergency state.

It is worth mentioning that the restoration of 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 door locks 20 before entering the first priority emergency state. Each is independently set to be locked, and the other part of the door lock 20 is independently set to be unlocked. After the first priority emergency state is released, the part of the door lock 20 that is set to be locked remains locked but can be independently locked. The operation is unlocking, and the other part of the door lock 20 that was set to unlock 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 and the emergency control unit 40A are physically separated 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 locked. Keep the unlocking authority S203. If the second priority emergency state is set, all door locks will be set to the locked state S205 and the unlocking 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 After 52 or smart mobile device 50 logs into 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, it cannot 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 33 is in the emergency control unit When the 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 use the first handle 34A to operate the latch. 23 is moved 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 device 32 of all door locks 20 will issue an emergency warning signal .

When 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 the door locks 20 are set to the locked state, the alarm system is communicated. In detail, the control device 33 Drive the safety notification device 54 to notify the police system (report) of an emergency (such as a gangster breaking into the campus).

When entering the second priority emergency state, the control device 33 drives the alarm 62 to generate an alarm, and 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, so that the adjacent control device 33 Of people learn about an emergency (such as the principal’s office or guard room on campus).

Whether to cancel the second priority emergency state S207, log in to the background when the emergency control unit 40A is physically separated from the connector 38 of the control device 33, and you can choose to cancel the second priority emergency state S207. If the second priority emergency state is canceled, all doors The lock 20 is restored to the unlocking authority S209 and the alarm 62 stops functioning. If the second priority emergency state is not lifted, all the door locks 20 will remain without the unlocking authority. In detail, after the emergency condition is lifted (for example, the gangster is arrested) and When the emergency control unit 40A is physically separated from the connector 38 of the control device 33, log in to the background, and you can choose to press the second priority emergency icon (Icon) on the background interface to restore the unlocking authority. S209 generates an alarm message for each door lock 20 and stops the continuous operation of the alarm 62. If the second priority emergency status icon is not pressed, all the door locks 20 remain in the state of losing the unlocking authority S211 and the alarm 62 keeps operating. Alarm message.

It is worth mentioning that if the emergency control unit 40A is physically connected to the connector 38 of the control device 33 when entering the second priority emergency state, the control device 33 will enter the first priority emergency state S105 , So even if you use the computer 52 or smart mobile device 50 to log in to the background interface and press to release the first or second priority emergency state, it still cannot restore any one of the door locks 20 to unlock permissions, which can prevent the administrator’s computer 52 Or the smart mobile device 50 is robbed by criminals to restore the unlocking authority of each door lock 20.

In addition, the restoration and unlocking authority can also be set to restore the state of each door lock 20 before entering the second priority emergency state together. For example, a part of all door locks 20 are independently set before entering the second priority emergency state. In order to lock, the other part of the door lock 20 is independently set to unlock. After the second priority emergency state is released, the part of the door lock 20 set to be locked remains locked but can be independently operated as unlocked. The other part of the door lock 20 that was set to be unlocked before entering the second priority emergency state returns to unlock after the second priority emergency state is released and can be independently operated to be locked.

The security-improved access control method of the present invention further includes whether to enter the fire control state S301. When all the fire detection devices 56 connected to the control device 33 do not detect a fire, all the door locks 20 remain unlocked. Authority S303, when any one of the fire detection devices 56 detects a fire, the control device 33 controls the part of the door lock 20 at the position of the fire detection device 56 that detects the fire and makes it locked. Loss of unlocking authority. In addition, when entering the fire control state S301, the control module 33A executes the alarm S302, which drives the alarm 62 to generate alarm messages such as sound, light, or sound and light, so that personnel adjacent to the control device 33 can borrow It is learned that an emergency (fire) has occurred. In detail, the central control access control system 10 installs a plurality of fire detection devices 56 in appropriate places of the building. When at least one of these fire detection devices 56 detects In the event of a fire, the control device 33 automatically controls the corresponding part of the door lock 20 to be set to the locked state according to the position of the fire detection device 56 that detects the fire, so that part of the door lock is locked S305, so that the door cannot be opened can reduce the spread of the fire. speed. In addition, when a fire occurs, the control device 33 executes fire notification S307, that is to say, after entering the fire control state, the further control device 33 uses the fire notification device 58 to notify the fire fighting system of a fire, so that firefighters can rush to the fire scene to extinguish the fire. Fire.

The fire control state S309 is cancelled. If the fire control state is not cancelled, the door lock 20 that is set to the locked state due to the fire loses the unlocking authority S311 and the alarm 62 keeps operating and generates an alarm message. If the emergency control unit 40A and the control device 33 When the connector 38 is physically separated, log in to the background and choose to cancel the fire control state. The door lock 20 that was set to the locked state due to the fire restores the unlocking authority S313 and executes the cancel alarm S314, so that the alarm 62 stops operating. In detail, after the fire is extinguished, the administrator allows the emergency control unit 40A to be physically separated from the connector 38 of the control device 33 and allows to log in to the background and choose whether to press the icon to release the fire control state. (Icom), if you don’t press the icon to release the fire control status, each door lock 20 that is set to the locked status by the controlled device 33 will keep losing the unlocking authority S211 and the alarm 62 will keep operating and generate an alarm message. If you choose to press to release the fire control With the status icon, each door lock 20 set to the locked state by the control device 33 restores the unlocking authority S209, and the control module 33A executes the cancel alarm S212 to stop the operation of the alarm 62.

It is worth mentioning that the restoration unlocking authority S313 can also be set to restore the state of each door lock 20 before entering the fire control state. For example, a part of all door locks 20 are individually independent before entering the fire control state. Set to be locked, and the other part of the door lock 20 is independently set to unlock. After the fire control state is released, the part of the door lock 20 that is set to be locked remains locked but can be independently operated to unlock, so The other part of the door lock 20 that was set to be unlocked before entering the first priority emergency state is restored to unlock after the first priority emergency state is released and can be independently operated to be locked.

Set the third priority emergency state S401, use a remote control 60 to select at least one door lock 20 in an area to be remotely set to the locked state. If the third priority emergency state is not set, all the door locks 20 will maintain the unlocking authority S403, part The share door is set to the locked state S405. If the third priority emergency state is set, the set part of the door lock 20 is set to the locked state and loses the unlocking authority. In addition, when the third priority emergency state is entered, an alarm S408 is generated, making the control mode Group 33A drives the alarm 62 to generate a warning message, and personnel who are further close to the control device 33 can know that the third priority emergency state is entered. In detail, the remote control 60 of the central control access control system 10 and the receiver of each door lock 20 39 pairing, when the emergency control unit 40A is physically separated from the connector 38 of the control device 33, it can be used to set a single or multiple door locks 20 within a certain range to the locked state, and make these set to be locked The state of the door lock 20 loses the unlocking authority (the first or second manual setting device 26, 27 cannot be used to set the unlock state), and further the reminder device 32 of all the door locks 20 sends an emergency warning signal and sends back an emergency warning signal. The signal is sent to the control device 33, so that the control module 33A drives the alarm 62 to generate the alarm message S408, so that the personnel adjacent to the alarm 62 know that the third emergency state is entered from the alarm message sent by the alarm. This is suitable for providing managers in When an emergency occurs far away from the location of the control device 33 and the door lock 20 needs to be set to the locked state, the administrator can set at least one door in a smaller area faster than logging in to the background to set the second priority emergency state. Lock 20 is set to the locked state. In addition, it includes the third-level notification S406, after the third-level priority emergency state is set, the alarm system will be communicated.

To cancel the third priority emergency state S407, use the computer 52 or smart mobile device 50 to log in to the background when the emergency control unit 40A and the connector 38 of the control device 33 are physically separated, and allow the operation to cancel the third priority emergency state. If the third priority emergency state is not released by operation, the door lock 20 that is set to the locked state will lose the unlocking authority S409 and the alarm 62 will keep operating. If the third priority emergency state is released, the door lock 20 will be set to the locked state. Restore the unlocking authority S411 and cancel the alarm S410, so that the alarm 62 stops operating.

Gunshot control state S501, when none of the plurality of gunshot detection devices 61 detects a shooting event, it does not enter the gunshot control state S501, so each door lock 20 maintains the unlocking authority S503. If any one of the multiple shooting detection devices 61 detects a shooting event, it will report the shooting location S505, which reports the shooting location to the control device 33. In detail, for example, each shooting can be detected. Each device has a separate hardware identification code, and based on the hardware identification code, a database of the location of the gunshot detection device is established. When any one of the plurality of gunshot detection devices 61 detects a gunshot event, the detection device The gunshot detection device report signal that detects the gunshot contains its own hardware identification code, so that the control module 33A of the control device 33 can know the approximate location (within which range) where the gunshot occurred based on the report signal. In addition, when entering the gun control state S501, an alarm S507 is generated. The alarm S507 is generated by the control module 33A to drive the alarm 62 to continuously produce sound, light or sound plus light, so that the personnel adjacent to the control device 33 (for example, located at The principal in the principal’s room or the guard in the guard’s room) can learn about the shooting incident through the alarm 61, and the control device 33 drives the reminder device 32 of each door lock 20 to generate an emergency warning signal to notify the personnel in the place other than the shooting incident. In addition, it is allowed Log in to the background to view the approximate location of the shooting (the actual location of the shooting may be a distance from the shooting detection device 61), so that personnel (such as the principal located in the principal's room or guards in the guard room) can do the first time the shooting occurred. A quick response.

In addition, when entering the shooting control state S501, the shooting notification S508 is executed at the same time. The security notification device 54 is used to notify the police system of an emergency situation, so that the police can receive the notification in the shortest time and rush to the shooting location.

The door lock in the vicinity of the shooting is set to the locked state S509, and at least one door lock adjacent to the shooting place is set to the locked state. In detail, the control module 33A of the control device 33 is based on the detection of the detected shooting. The hardware identification code in the data identification returned by the device 61 identifies the location of the shooting, and the control device 33 controls at least one door lock 20 adjacent to the location of the shooting to be locked, so that the door lock 20 that is controlled to be in the locked state is lost Unlocking permissions is used to prevent or delay criminals from passing through the door control and reduce casualties.

The shooting control state S511 is released, and it is judged whether the person who initiated the shooting is subdued. If the person who initiated the shooting is not subdued, the at least one door lock 20 that is set to the locked state remains without the unlocking authority S513, if the person who initiated the shooting has been Is suppressed, the at least one door lock 20 set to the locked state restores the unlocking authority S515, so that the at least one door lock 20 can be operated independently, and the alarm S517 is cancelled at the same time, so that the alarm 62 of the control device 33 Stop continuing operation.

The security-improved access control method of the present invention enters the first priority emergency state when the emergency control unit 40A is physically combined with the control device 33, so that all the door locks 20 are set to the locked state at the same time and the unlocking authority is lost, so When applied in places such as campuses, government agencies, etc., it can respond quickly when an emergency occurs. For example, when a gangster breaks into the campus, entering the first priority emergency state makes all door locks set to the locked state, which can effectively prevent the gangster from moving.

The security-improved access control method of the present invention can be set to the second priority emergency state by logging in to the background through the computer 52 or the smart mobile device 50 when the emergency control unit 40A and the connector 38 of the control device 33 are physically separated At the same time, all door locks 20 are set to the locked state and the unlocking authority is lost, so that even if the administrator is not near the control device 33, the emergency control unit 40A cannot be physically connected to the connector 38 of the slave control device 33 in time. It is still possible to remotely control all door locks 20 at the same time and set them to the locked state.
