It is authenticated secondly through authentication, and after the first and second authentication, the third step is to operate in a non-contact manner through the process of automatically opening and closing doors, and the opening and closing doors are automatically opened, so even in a non-face-to-face state, items are brought into the front door and a certain amount of time is Through non-face-to-face operation in which the door closes when passed, it is possible to receive goods and also to realize a service that enables refrigerated delivery using this function. , It relates to a push-pull open/close door control method for controlling non-contact, non-face-to-face automatic entry and exit IoT, which enables low cost and miniaturization and can be manufactured at a low price.

Today, digital door locks are commonly installed in homes and offices. In general, a method of unlocking the door lock using an IC card is used instead of a method of releasing the door lock by inputting a password.

The password-type digital opening and closing door lock has a problem that the user can forget the number, it takes time to enter the password, and it is boring while using it, and it is difficult to enter the password properly, especially when drunk and unconscious. there was. Moreover, there is a problem that an unpredictable risk occurs when the password is stolen by a person without proper authority.

The IC card has the advantage of being simpler and time-saving than the password input method, but has the disadvantage of being highly likely to be lost.

A solution to improve the above problem is to use biometric technology.

Today, various attempts are being made to apply biometric technology in the field of access control. If the biometric technology can be implemented well, the problems of the conventional digital open/close door can be properly solved.

However, access control technology based on biometrics is generally applied in an office environment, and specifically applied to automatic doors that open and close in a sliding manner. A device in which a biometric module is directly embedded in a door lock housing installed in a general house door has not been commercialized, because of problems such as safety, reliability, and speed.

For example, considering a case where a face recognition module is installed in an opening/closing device, if it takes time for the face recognition module to recognize a user's face, inconvenience will be caused to the user immediately. Since face recognition does not work properly in an environment where you want to enter and exit at night, that is, in a dark place, a face recognition module could not be smoothly installed in a home door lock device. That is why it was difficult to industrialize the face recognition based door locking device.

In addition, it is difficult to automatically open and close the swing door, which is currently widely used at home, and there is a problem that it is difficult to apply a non-contact non-face-to-face automatic entry and exit method based on IoT control at home.

In the existing door lock system using an LCD module, a sensor unit, a camera, and a face recognition unit must all be provided for the face recognition function, and the sensor unit, camera, and face recognition unit must all be provided inside the door lock. As it becomes larger and heavier, the price increases and it is inconvenient to use, so it is ignored by consumers.

And, currently, when receiving a courier through the door lock system, the door is opened and received, or the parcel is received in the form of leaving an object in front of the front door, so there is a problem in that the risk of loss of the delivered object is high.
