Directional positioning electronic door lock unlocking control system

Abstract

This invention provides a directional positioning electronic door lock unlocking control system, comprising an electronic door lock, an electronic key, an ultra-wideband positioning module, a direction determination unit, a position determination unit, and an unlocking control unit. The ultra-wideband positioning module is disposed on the electronic door lock and the electronic key to measure the distance, direction, or position of the electronic key relative to the electronic door lock. The direction determination unit and the position determination unit determine whether the electronic key is located within a preset allowed area relative to the electronic door lock based on the ultra-wideband signal. When the electronic key is located within the preset allowed area and meets the authentication conditions, the unlocking control unit allows the electronic door lock to unlock. Therefore, this invention avoids triggering unlocking even when the electronic key is close but actually inside the door, on the side of the door, behind a wall, or in another unallowed direction, thereby improving the positioning accuracy and unlocking security of the electronic door lock.

Claims

1. A directional positioning electronic door lock unlocking control system, comprising: An electronic door lock is installed on one door. An electronic key for communicating with an electronic door lock; an ultra-wideband positioning module, including an ultra-wideband unit disposed on the lock end of the electronic door lock and an ultra-wideband unit disposed on the key end of the electronic key, for obtaining positioning information of the electronic key relative to the electronic door lock; a direction determination unit connected to the ultra-wideband positioning module, for determining the direction of the electronic key relative to the electronic door lock based on the positioning information; a position determination unit connected to the ultra-wideband positioning module, for determining whether the electronic key is located within a preset allowed area based on the positioning information; and an unlocking control unit connected to the electronic door lock; wherein, when the direction determination unit determines that the direction of the electronic key meets a preset direction condition, and the position determination unit determines that the electronic key is located within the preset allowed area, the unlocking control unit allows the electronic door lock to unlock.

2. The electronic door lock unlocking control system with orientation positioning as described in claim 1, wherein the positioning information includes the distance, angle, orientation, front-back direction, left-right direction, or coordinate information of the electronic key relative to the electronic door lock.

3. The directional positioning electronic door lock unlocking control system as described in claim 1, wherein the preset allowed area is located outside the door and in front of the electronic door lock.

4. The electronic door lock unlocking control system with directional positioning as described in claim 1, wherein the preset allowable area includes a preset distance range and a preset angle range.

5. The electronic door lock unlocking control system with directional positioning as described in claim 1, wherein the direction determination unit determines whether the electronic key is located in front of, behind, to the left, to the right, or diagonally to the electronic door lock.

6. The directional positioning electronic door lock unlocking control system as described in claim 1 further includes an authentication unit for determining whether the electronic key is legally authorized.

7. An electronic door lock unlocking control system with directional positioning as described in claim 6, wherein the unlocking control unit allows the electronic door lock to unlock only when the direction, the preset permitted area, and the legal authorization are all met.

8. The directional positioning electronic door lock unlocking control system as described in claim 1, wherein the preset allowed area is set by an administrator through an application, installation setting interface or door lock management platform.

9. The directional positioning electronic door lock unlocking control system as described in claim 1, wherein the system has a calibration program for establishing or correcting the preset allowed area based on positioning data when the electronic key is in different positions.

10. The directional positioning electronic door lock unlocking control system as described in claim 1, wherein the unlocking control unit allows the electronic door lock to unlock only after the electronic key has remained in the preset permitted area for more than a predetermined time.
