Abstract

A method for controlling door access in a gunshot event includes connecting door locks with a control device. Each door lock retains its unlocking authority when no gunshot event is detected. A gunshot event information containing the gunshot location is sent to the control device when the gunshot event is detected, and the control device reports the gunshot location to the police system. At least one of the door locks near the gunshot location is set to the locking state, and the unlocking authority of the at least one door lock is revoked. Furthermore, the control device simultaneously sets the door locks to a locking state or an unlocked state through physical connection with or disconnection from an unlocking device. When the unlocking device is removed, the control device enters a first priority emergency state, such that all door locks are set to the locking state and lose unlocking authority.

Claims

1. A method for controlling door access in a gunshot event, comprising:

connecting a plurality of door locks with a control device, with the control device obtaining control authority of each of the plurality of door locks;

physically and removably connecting an unlocking device with the control device, with the control device identifying the unlocking device, wherein the control device actuates and sets all of the plurality of door locks to a locking state when the unlocking device is identified as being incorrect, and wherein each of all of the plurality of door locks obtains unlocking authority when the unlocking device is identified as being correct;

simultaneously setting all of the plurality of door locks connected to the control device into the locking state when the unlocking device is physically removed from the control device, and the control device enters a first priority emergency state, wherein all of the plurality of door locks lose the unlocking authority and are incapable of being unlocked independently;

sending a first-class report to a police system after all of the plurality of door locks have lost the unlocking authority;

physically reconnecting the unlocking device with the control device, with the control device re-identifying the unlocking device, wherein all of the plurality of door locks remain in the locking state and lose the unlocking authority when the unlocking device is re-identified by the control device as being incorrect;

logging in a backstage with a computer or a smart mobile device with a preset account and a password to connect with the control device when the unlocking device is re-identified by the control device as being correct;

selectively lifting or not lifting the first priority emergency state after logging in the backstage, wherein all of the plurality of door locks set in the locking state remain in losing the unlocking authority when the first priority emergency state is not lifted, and wherein all of the plurality of door locks set in the locking state restore the unlocking authority and a locking authority and are capable of being operated independently when the first priority emergency state is lifted while the unlocking device is re-identified by the control device as being correct;

detecting whether the gunshot event occurs, wherein each of the plurality of door locks retains the unlocking authority when no gunshot event is detected, wherein a gunshot event information containing a gunshot location of the gunshot event is sent to the control device when the gunshot event is detected, and wherein the control device reports the gunshot location to the police system;

setting at least one of the plurality of door locks near the gunshot location to the locking state and revoking the unlocking authority of the at least one of the plurality of door locks, and entering a gunshot control state;

selectively lifting or not lifting the gunshot control state after logging in the backstage while the unlocking device is physically connected to the connector, wherein the at least one of the plurality of door locks near the gunshot location loses the unlocking authority when the gunshot control state is not lifted, and wherein when the gunshot control state is lifted, the at least one of the plurality of door locks near the gunshot location restores the unlocking authority.

2. The method for controlling door access in the gunshot event as claimed in claim 1, further comprising:

generating an alarm when the control device receives the gunshot location information of the gunshot event; and

deactivating the alarm when the gunshot control state is lifted.

3. The method for controlling door access in the gunshot event as claimed in claim 1, further comprising:

selectively setting or not setting a second priority emergency state after logging in the backstage while the unlocking device is physically connected to the control device, wherein all of the plurality of door locks retain respective unlocking authority when the second priority emergency state is not set, and wherein all of the plurality of door locks are set to the locking state and lose the unlocking authority when the second priority emergency state is set;

sending a second-level report to the police system when the second priority emergency state is set and all of the plurality of the door locks are set to the locking state; and

selectively lifting or not lifting the second priority emergency state after logging in the backstage while the unlocking device is connected to the control device, wherein all of the plurality of door locks restore the unlocking authority when the second priority emergency state is lifted, and wherein all of the plurality of door locks lose the unlocking authority when the second priority emergency state is not lifted.

4. The method for controlling door access in the gunshot event as claimed in claim 3, further comprising:

selectively setting or not setting a third-level emergency state, wherein the third-level emergency state is set by using a remote controller to remotely set at least one of the plurality of door locks in an area into a locking state, and the at least one of the plurality of door locks loses the unlocking authority when the third-level emergency state is set, wherein all of the plurality of door locks retain the unlocking authority when the third-level emergency state is not set;

reporting to the police system after the third-level emergency state is set; and

selectively lifting or not lifting the third-level emergency state after using the computer or the smart mobile device to log in the backstage while the unlocking device is identified as being correct, wherein the at least one of the plurality of door locks set in the locking state remains in loss of the unlocking authority when the third-level emergency state is not lifted, and wherein the at least one of the plurality of door locks set in the locking state restores the unlocking authority when the third-level emergency state is lifted.

5. The method for controlling door access in the gunshot event as claimed in claim 4, wherein each of the plurality of door locks includes an indicating device, wherein each indicating device sends out an emergency alarm signal when one of the first emergency state, the second emergency state, the third emergency state, and the gunshot control state is entered.

6. The method for controlling door access in the gunshot event as claimed in claim 1, further comprising:

connecting the control device with a fire detection device, wherein each of the plurality of door locks retains the respective unlocking authority when the fire detection device detects no presence of a fire, and wherein the control device sets a portion of the plurality of door locks near the fire into the locking state when the fire detection device detects the presence of a fire, wherein the portion of the plurality of door locks lose the unlocking authority, wherein the control device enters a fire control state, and wherein the fire is reported to a fire system through a fire reporting device connected to the control device; and

selectively lifting or not lifting the fire control state, wherein the portion of the plurality of door locks set in the locking state owing to the fire loses the unlocking authority when the fire control state is not lifted, and the portion of the plurality of door locks set in the state owing to the fire restores the unlocking authority when the fire control state is lifted after logging in the backstage while the unlocking device is connected to the control device.

7. The method for controlling door access in the gunshot event as claimed in claim 6, wherein each of the plurality of door locks includes an indicating device, wherein each indicating device sends out an emergency alarm signal when the fire control state is entered.
