The present invention relates to a security device that wirelessly supplies power and uses the same to receive a password embedded in an electronic key to determine it. The present invention relates to an electronic device that maximizes its function as a locker because it does not exist in the locker.

As security awareness about personal information and corporate information has matured recently, the demand for security is increasing day by day. In particular, since the access control system is the basis of the security system, it is an area that is attracting attention as the market opens first. When it comes to access control, it's easy to think of permission and disapproval, but recently, systems with various functions such as time and attendance management have been in the spotlight.

This field of electronic access control system is not only convenient, but also solves the problem of coercive disengagement of the lock device using a conventional mechanical key. In the existing seam using the mechanical key, the insertion hole of the key for the insertion of the key is an essential component, and such an insertion hole could be damaged by an unauthorized person inserting a special device into the insertion hole and forcibly applying physical force.

According to another aspect of the present invention, the key determination means 20 is subjected to a learning process in which the key input by the user is transmitted to the key through the key determination means 20 and the wireless key is applied again through the key. It is possible to make it possible to use for self-identification, and it is characterized in that the power can be provided by the key discriminating means (20).

Hereinafter, with reference to the accompanying drawings with respect to an embodiment of the present invention keypad type electronic key device as follows.

1 is a block diagram showing a key input means 10 as an embodiment of the present invention.

As shown in the figure, the electronic key device according to the present invention is composed of a register means 11, a controller means 12, a decryptor 13, an interface 14 and the flash 15.

Electronic key input means should be performed before operating the learning process to receive the password from the key determination means. The authorizes the password in the key discrimination means before operation. This is stored in the flash 23 and input to the key delivery means 10 through the learning process. The input data is shown as S-data in FIG. 1 and S-clk is a clock used for data synchronization. The data thus transmitted is transmitted to the decryptor 13 via the interface 14, interpreted, and stored in the flash 15 by the controller 12. The stored password is transmitted to the key discrimination means 20 via the interface 14 by the operation of the key button 11 of the approver.

The key determination means for granting a password to the electronic key input means transmits the password inputted by the author via the antenna 21 to the key input means, and supplies power to the key input means during the operation of the system after completing the learning process. And compare the signal transmitted from the key input means.

The driving means for driving the motor to lock and open the door according to the determined result of the key determining means 20 is turned on when the password is correct as a result of the determination of the key determining means 20 to supply the motor driving voltage. It has a motor drive means 29.

Then, the alarm means 28 for notifying the user of the current operation status and number error by the key discrimination means 20 is controlled by the control signal of the key discrimination means 20 during the user's current password input process or change. The LED is notified to the user through the light-emitting diode 30, and when the wrong number of inputs and low voltage, the buzzer 28 generates a warning sound.

Reference numerals Ma to Mb are switching units, R1 to R2 are resistors, C is a capacitor, and Z1 to Z2 are zener diodes.

Referring to the accompanying drawings, the operation of the non-powered electronic lock apparatus configured as described above is as follows.

First, the password is transmitted to the key input means 10 through the antenna provided in the key determining means 20, which is completed only before the operation by the authorized person, and when the password is to be changed, the new password is also changed by the authorized user. Another course of learning is required with authorization.

In this case, when the key discrimination means 20 outputs a high signal through a terminal to inform the user of the state in which the key is being input to the alarm means 23, the light emitting diode 30 emits light.

That is, the light emitting diode 30 emits light during the password checking process to inform the user that the current password is input, and also informs that the light is being changed during the password change.

Thereafter, the key determining means 20 compares the password stored in the key signal input from the key input means 10 and performs the control operation according to the internal control procedure according to the result. Accordingly, when the password is correct, the high signal is output to the terminal connected to the controller 27, so that the motor driving means 29 is turned on to make the door open.

On the other hand, when the password input from the user is incorrect or the power supply voltage is low voltage, the controller 27 outputs a control signal to the alarm means 28 through the terminal, so that the buzzer 28 of the alarm means generates a warning sound. .

The key determining means 20 may learn a plurality of key input means 10. In this process, the key determining means 20 reads the password of and calculates the key of the key input means 10.

The key determination means 20 then retrieves the received password through the database. If the data obtained by the key discrimination means is not registered, access to the key input means 10 is not permitted. Therefore, in order to operate such a system, a learning process is required before driving. In order to perform this learning process, the learning must be performed by the licensor with the acquisition of the system.

Communication between the key input means 10 and the key discrimination means 20 takes place by a magnetic field coupling between the coil of the key and the key discrimination means coil. The key discriminating means coil comprises a series configuration of a resistor, an inductor, and a capacitor circuit. The key discrimination means communicates with the electronic key by connecting and shorting the RLC circuit as a signal of 125 KHz. Therefore, the key discrimination means magnetic field is also connected and short-circuited. The coil of the key input means 10 is connected in parallel with the resonant capacitor of 125KHz and the circuit of the key input means 10. When the key input means 10 approaches the magnetic field of the key discrimination means, it is magnetically coupled with the field and takes energy from it. This phenomenon can be observed as the voltage of the resonant capacitor of the key discriminating means decreases.

The key input means 10 communicates with the key determination means by shorting this LC circuit. As a result, the key input means 10 is de-tuned and the load is removed. This load increases the voltage across the key discriminating means resonant capacitor. The key discriminating means capacitor voltage is input to the AM demodulator circuit of the key discriminating means. The demodulator uses key discrimination means software to pick up key input means 10 data for further processing.

As described above, the present invention relates to a wireless-powered electronic key device, since the power of the key input means is received from the key discrimination means, the size of the portable key input means that can be carried is not only easy to carry. The present invention has the effect that the exposure of the password can be minimized compared to the existing keypad-type key device because the key is transmitted over the air.

While the invention has been shown and described in connection with certain preferred embodiments, it will be appreciated that various modifications and changes can be made without departing from the spirit or the scope of the invention provided by the following claims for utility model registration. Those of ordinary skill in the art can easily know.
