5 is a detailed block diagram of the wireless ID door lock apparatus according to the embodiment of the present invention.

1) lock open / locked

First, when the user touches the touch switch 410 by hand, the microcomputer 540 detects a touch signal input through the switch detector 510 to turn on the main battery power supply 590 so that the circuit operates normally. The touch switch detector 510 is always powered from the main battery power source 590 regardless of the touch signal. At this time, the radio wave transmitter 520 first transmits radio waves through the antenna 430 to read ID data from the RF electronic key 120. When the RF electronic key 120 approaches a certain distance or less when the radio wave is transmitted, the RF electronic key 120 transmits unique ID data recorded in the RF electronic key 120 at the moment of receiving the radio wave. Data is input to the RF data receiver 530 through the antenna 430. The RF data receiver 530 converts the microcomputer 540 into readable data and transmits the data to the microcomputer 540. The microcomputer 540 first reads the master ID data from the master ID storage ROM 550 and compares it with the ID data of the current read 610. Here, if these two ID data match, the lock unit 580 is controlled. Here, when controlling the lock unit 580, if the lock unit 580 is in a locked state, the lock unit 580 is opened, and if the lock unit 580 is open, the lock unit 580 is locked.

Here, the data of the master ID storage ROM 550 uses a ROM that prevents data from being erased or newly written. That is, by allowing one door lock device to have a unique master ID, the master ID cannot be changed, and when the master electronic key ID is detected, the auxiliary key ID can be registered or deleted. This operation will be described later.

When there is a mismatch between the data read from the master ID storage ROM 550 and the data read from the external RF electronic key 120, the ID data of the auxiliary ID storage EEPROM 570 storing the auxiliary IDs is read and compared. . The reason for using EEPROM is to prevent the IDs of registered auxiliary keys from being erased even if the power is not supplied. When there is an ID that matches the ID data read from the external RF electronic key 120 among the auxiliary ID data read from the auxiliary ID storage EEPROM 570, the lock is controlled by controlling the lock unit 580 as in the above-described operation. Open or lock depending on the condition of the device.

If neither the master ID nor the auxiliary IDs match, no action is taken. In addition, when a predetermined time passes after the touch is detected by the touch switch detecting unit 510, the microcomputer 540 blocks the main battery power supply unit 590 again until the next touch switch detecting unit 510 detects a touch. Make sure there is no power consumption.

In addition, the locking device can be locked or opened manually by using the manual locking device (581).

2) Auxiliary Key ID Registration

First, the master electronic key 600 is operated in the same manner as 1) above to recognize the microcomputer 540 that the master ID has been input, and then, while the registration button of the registration / delete button input unit 560 is pressed, is registered. The new auxiliary electronic key 610 is approached to the antenna 430 by a predetermined distance or less. At this time, the microcomputer 540 registers the ID of the auxiliary electronic key 610 input from the RF data receiving unit 530 by writing the ID data to the auxiliary ID storage EEPROM 570 while the registration button is pressed. . The auxiliary electronic key 610 having the ID registered in this way is allowed to enter and exit through the door lock device in the same manner as the operation 1).

3) Delete Secondary Electronic Key ID

In the case where the auxiliary electronic key 610 registered in the auxiliary ID storage EEPROM 570 of the door lock device is lost, all of the IDs stored in the auxiliary ID storage EEPROM 570 may be deleted. First, as shown in 1), the microcomputer 540 recognizes the master ID, and when the delete button is pressed, the auxiliary IDs stored in the auxiliary ID storage EEPROM 570 are deleted. In this way, the lost auxiliary electronic key cannot be accessed again.

The present invention is a door lock device using an invisible wireless RF technology, the ID of the electronic key to allow access to the door lock is not exposed, the security is excellent, unlike the existing RF access control system, the door lock circuit It is built in the device and consumes power only when it is operated by using a touch switch, so it can be used for home use with low power and low power consumption.

In addition, the ID of the new RF electronic key can be registered by using the master key to allow access or to delete the ID of the lost electronic key, thereby improving security and allowing access to multiple door locks with one electronic key. On the contrary, it is convenient to use as it can be extracted and extracted as a plurality of electronic keys in one door lock.
