Description

DEVICE AND METHOD OF AUTOMATIC ACCESS CONTROL FOR MECHANICAL LOCK

Technical field

The present invention relates to a mechanical electrical device for mechanical lock, as well as a method for access control, whereby the present invention is in the field of access control and door security, in particular devices for mechanical locks and methods to automate the authorization and permission to enter certain places and / or environments according to previously registered privileges.

State of the art

At present, there are several accessories for actuating a lock, for example the one described in US9322194 which deals with a system for an intelligent bolt, is provided with a positioning detection device configured to be coupled to a drive shaft of a device with bolt. The position sensing device detects the position of the drive shaft and helps to lock and unlock a lock of a bolt device. A motor is provided with a memory coupled to the positioning sensor device. A circuit is coupled to the motor and a power source is coupled to the circuit. A device converts electrical energy into mechanical energy and is coupled to the circuit, the detection device positioning and the drive shaft. The device that converts energy is coupled to the power source to receive energy from the power source. US20160097220A1 patent deals with a keyless locking system includes not only an electromagnetic switch system, a fingerprint identification system, but also includes a combination code system through a Bluetooth wireless connection to a Smart phone or external device. The electromagnetic switch system can secure a piece of furniture or any lock. The system can be secured mainly by force and vibration from outside the cabinet. Fingerprint identification provides the locking device for easy operation without a key. The combination code can be used on the keyboard device and is used on the smartphone via a wireless Bluetooth connection. The combination code can be reset by smartphone or external device. A battery system and variable power supply will keep the system information up to date without losing memory if the system loses power.

These accessories for locks have the same purpose of automating the functionality of a door for opening or locking, imply a disassembly of the lock to replace certain parts; In addition, they are for bolt-type systems and only open and close, since a bolt is a simpler type of lock and includes a latch that is compressed during door closing and then extends into a door opening when The door is completely closed. It should be emphasized that these can be easily violated.

Taking into account the above, it is difficult to obtain a device and a method to control a three-state mechanical lock: open (without latch or latch), without bolt (only with latch) and with bolt (with latch and bolt), which allows adequate control, provide security and allow to automate the opening and closing of conventional mechanical locks and, therefore, the access of certain environments from previously configured permits. Description of the invention

The present invention solves the problems set forth above since it consists of a device that adapts to a mechanical lock. conventional; thanks to its particular mechanical design, an increase in torque and an increase in the degree of rotation to the servomotor is provided. In addition, its installation does not imply any modification of the lock since it turns the same key placed inside the environment.

The device of the invention uses a gear train for mechanical control of the lock by means of the decentralized device for access control (25) that enables a biometric identification device (26) when the user identifies biometrically, it stores this temporary identification , then compare this identification with its database, define the similarity score, perform the validations and privileges, type of schedule and type of configuration, valid that the person has authorization to access that area / environment, validates that the person is in the allowed time, validates the privileges of the person, allows the access of the person when it is verified that all the privileges are correct, for which the decentralized device for access control (25), sends a signal to the servomotor, the which triggers the lock.

The proposed invention mainly comprises at least one housing (20), a positioning sensor (16), a decentralized device for access control (25) and a servomotor (19) connected to the decentralized device for access control (25), characterized because at least three gears (18) attached on a base (5) are installed in the housing (20) where the first gear is connected to the servomotor (19) and leads the rotation to a second gear that is connected to the sensor positioning (16) and a third gear which in its center has a groove adaptable to any key and that drives the rotation of the key of the lock; and an identification device connected to the decentralized device for access control (25). The identification device that is connected to the decentralized device for access control (25) is a biometric sensor such as an identifier of fingerprints or retinas, being able to be an identifier of iris, fingerprint, palm, face / gesture, voices, or Similar. The housing of the device has a circular toothed rack inside that allows its mechanical operation by friction and grip when turning the housing, allowing the opening of the lock in case of emergency and even in situations of lack of energy.

For its part, the cover of the device has a panel with three touch buttons arranged symmetrically in a triangular position that allow the three states of the lock identified with light-emitting diodes to be activated that allow to visualize the condition of closed, open and closed without bolt .

The invention also relates to a method for access control which, through independent devices that identify a person by means of biometrics and that homologize the data through a cloud system, allow validating whether the user has authorization to enter or access a certain area or environment depending on the permissions and configuration of the device. This system / method can also be configured to control the assistance, in which case it will save the action registered by the user and subsequently execute the activities as the case may be; This method allows an incident report to be generated in all cases.

Access controls are provided to companies and / or independent users for security reasons, these access controls are determined to improve the security of the area and automate the entry and exit of registered users, while the assistance control alternative allows also carry out the automatic control of compliance of schedules of the personnel in a company. The method for access control proposed by the present invention requires the intervention of a decentralized device for access control (25) containing the approved information; to obtain approval the device is located in any area with internet access and obtains the homologation of data through a system in the cloud (24) arranged for these purposes, to generate the approved biometric data the following process is followed: the system in the cloud (24) sends a command and the information to the device Selected decentralized, the person registers their biometric identification, the device validates that there is no such identification in the system, the device saves the identification in its local database, the device sends the identification and data to the web platform, the web platform sends the new identification and data to the other connected and linked devices, queuing those that are not connected (so that when they connect they get the information).

For the access control of a previously approved user, the following method is followed: first the device enables biometric identification capture, then the user identifies biometrically, the system saves this temporary identification and compares this identification with its database; The system defines the similarity score and performs the validations of privileges and permissions, type of schedule and type of device configuration. For the purposes of access control, in turn, it is valid that the person has authorization to access that area / environment, validates that the person is allowed, validates the privileges of the person, if these validations are favorable, the device it allows the access of the person using the electro mechanical access control device referred to in the present invention. In case of the alternative functionality for "assistance control" the method requires that the device save the action or dialing registered by the user, validate the action performed according to the defined schedule, establish the defined tolerances and times. In the case of joint configuration for "assistance control and access control" the method validates the identification of the person, the system waits for the action to be performed by the user (for example, pressing a button, making a gesture, saying a sentence, touch the device, make a sound, look at the device, turn a knob), and the system executes the activities according to the option chosen.

In all cases the device generates an incident report / event history. When the device is connected to the internet, it sends this data to the cloud, otherwise it is stored in a queue, so that they are sent later when the device is connected online.
