1 is a view showing a configuration of a door lock according to the present invention.

1, the door lock according to the present invention compares an iris pattern of a user who has approached a door lock with a previously stored iris pattern, and authenticates a user who approaches the door lock according to the comparison result. A microcontroller 102 for controlling the opening and closing of the door based on the result of the user authentication, a battery unit 101 for IRIS module for high-rate discharge, A first switch 105 for interrupting the power supply to the iris recognition module 101 from the battery unit 103 for the iris recognition module; And a second switch 106 for interrupting power supply to the iris recognition module 101 through the first switch 105 in the door lock battery unit 104, High-rate discharging iris (DC) voltage of each of the battery module 103 and the battery module 104 for low-rate discharge is measured, and when the iris recognition operation of the user approaches the digital door lock, When the battery voltage level of the iris recognition module 103 exceeds the set level, the first switch 105 is turned ON to supply power to the iris recognition module 101 only in the battery unit 103 for the iris recognition module And when the battery voltage level of the battery unit 103 for the iris recognition module falls below the set level, the second switch 106 is turned on and the first switch 105 is also turned on ON) state so that the iris recognition module 101 is also supplied with power by the door lock battery.

That is, the battery unit of the door lock according to the present invention is used for an iris recognition module (IRIS module) which performs a high rate discharge (several hundred mA for several seconds during main processor operation, several A current consumption for several mS during LED instantaneous light emission) (E.g., battery packs) 103 and 104 for the door lock.

The supercapacitor 109 is added to prevent the instantaneous voltage drop of the edible power source, which is the iris consumed by the instantaneous number A. [ Specifically, the supercapacitor 109 is installed to apply an instantaneous voltage drop prevention power to the iris recognition module as a signal line for transmitting the power of the battery unit 103 for the iris recognition module to the first switch 105 This compensates the voltage generated when the instantaneous voltage drop occurs. This supercapacitor should be large enough to be added to the iris recognition battery pack when the iris recognition battery pack and the digital door lock battery pack are separated. When connected to a battery pack for digital door lock, problems such as reset anxiety arise.

The first switch 105 is provided between the iris recognition module battery 103 and the iris recognition module 101 to intermittently supply power to the iris recognition module 101 from the iris recognition module battery 103 will be. In the iris recognition operation of the user who has approached the digital door lock, the power intermittence operation is performed in a case where the battery voltage level of the battery unit 103 for iris recognition module does not fall below a certain level, ON state, and the power is supplied to the iris recognition module 101 only from the battery for the iris recognition module. When the battery voltage level of the battery unit 103 for the iris recognition module falls below a certain level and the second switch 106 is turned on, the power is supplied to the iris recognition module to supply the iris power to the digital door lock battery .

The second switch 106 is provided between the battery unit 104 for digital door lock and the first switch 105 and is connected to the iris recognition module 101 ). In the power intermittent operation, when the battery voltage level of the battery unit 103 for the iris recognition module falls below a certain level in the iris recognition operation of the user who approaches the digital door lock, a state in which the control signal is received from the microcontroller 102 So that the iris power is supplied to the battery for the digital door lock. Initially, the iris recognition module is initially turned off when the iris power source is used as the power source of the battery unit 103 for the iris recognition module.

The iris recognition module 101 (IRIS Module) receives power only from the battery for the iris recognition module at the initial stage of the iris recognition operation of the user, and when the voltage level of the iris recognition module battery drops below a certain level, ) Is supplied with iris power. For example, if the voltage level of the battery for the iris recognition module does not fall below a predetermined value at the time of inputting a signal that detects the user's approach from the proximity sensor 107 or when inputting the wake-up key signal of the user from the wake- The microcontroller 102 turns on the first switch 105 in order to recognize the iris of the user approaching the iris recognition module. When the voltage level of the battery for the iris recognition module drops below a predetermined value at the time of inputting a signal sensing the user's approach or inputting a wake-up key signal of the user from the wake-up key, the microcontroller 102 controls the second switch 106 The first switch 105 is turned on to supply the iris power to the digital door lock battery. Thus, the battery replacement timing can be matched. The iris recognition module 101 receives a signal from the proximity sensor 107 that senses the user's approach or inputs a wake-up key signal of the user from the wake-up key and receives a photographing start signal from the microcontroller 102 The iris recognition operation is performed. That is, a photographing signal is input to the iris camera in accordance with the photographing start signal inputted from the microcontroller 102, and a lighting signal is inputted to the high luminance LED according to the lighting start signal input from the microcontroller 102, do. When the door lock 200 is driven, the iris recognition module 101 compares the iris pattern of the user who has approached the door lock with the previously stored iris pattern, and authenticates the user who approached the door lock according to the comparison result. That is, the iris recognition module 101 authenticates a user who accesses the door lock through iris recognition, and applies user authentication by inputting a cryptographic key separately from iris authentication. Specifically, in the preferred embodiment of the present invention, the user is authenticated through the iris pattern comparison. The authentication process by inputting the encryption key is not performed after the iris authentication process, or only the authentication process by inputting the encryption key is performed through the user authentication process. The iris camera captures the iris of the user and acquires the iris image. For example, a face photographing camera photographs a face of a user who approaches a door lock. When the eye position is sensed in the photographed face image, the iris camera acquires the iris image by photographing the iris of the user based on the sensed eye position information. At this time, a tilt mechanism is applied to the iris camera, and the inclination and operation of the iris camera are controlled by servo control. Then, the main processor extracts the iris pattern and the like from the iris image, compares the extracted iris pattern and the previously stored iris pattern, and performs the initial security authentication of the user according to the comparison result.

When the battery voltage level of the battery unit 103 for the iris recognition module exceeds the set level, the first switch 105 is turned on, When the iris recognition module 101 supplies power only to the battery module 103 for the recognition module and the battery voltage level of the iris recognition module battery 103 falls below the set level, So that the first switch 105 is also turned on so that the iris recognition module 101 is supplied with the door lock battery. For example, when a signal that detects the user's approach from the proximity sensor 107 is inputted or a wake-up key signal of the user is input from the wake-up key, and the battery voltage level of the battery unit 103 for the iris recognition module is The first switch 105 is turned ON to supply power to the iris recognition module 101 only in the battery unit 103 for the iris recognition module, The second switch 106 is turned ON when the battery voltage level of the door lock switch 103 is lower than the set level and the first switch 105 is also turned ON, And power is supplied to the iris recognition module 101 with a battery. When the microcomputer 102 detects a user's approach from the proximity sensor 107, or when a wake-up key signal is input from the wake-up key, the microcontroller 102 transmits a photographing start signal to the iris recognition module 107. [ And inputs it to the main processor of the controller 101 to perform the iris recognition operation. At this time, the high luminance LED is turned on by inputting the lighting start signal of the high luminance LED.

The ten-key unit 108 is a further example of a configuration for authenticating a user who has approached the door lock, and receives a cipher key from a user through a ten-key pad. Thereafter, the ten key control chip compares the input encryption key with a predetermined encryption key, and authenticates the user based on the comparison result.

At this time, the supercapacitor is supplied with a power source for preventing instantaneous voltage drop of the power for the iris recognition module as a signal line for transmitting the power of the battery unit for the iris recognition module to the first switch, ) Is compensated for the voltage generated at the instantaneous voltage drop.

On the other hand, when the battery voltage level of the battery unit for the iris recognition module falls below a predetermined level, the second switch for interrupting the power supply from the digital door lock battery unit to the iris recognition module is turned ON, (S205) so that the iris recognition module supplies the iris power to the door lock battery.

This operation is performed, for example, as follows.

That is, when the proximity sensor detects the user's access to the digital door lock or the wake-up key is input according to the key operation of the user who accesses the digital door lock, The iris recognition operation is started.

If the battery voltage level of the battery unit for the iris recognition module does not fall below a certain level, that is, exceeds the set level, the battery unit for the iris recognition module checks the battery voltage of the battery unit for the iris recognition module. The first switch for interrupting the power supply is turned ON so that the iris recognition module supplies the iris power to only the battery unit for the iris recognition module.

At this time, a control signal (an iris camera photographing start signal or the like) for starting the operation of the iris recognition module is applied to the main processor of the iris recognition module, and the user's iris Thereby allowing the recognition operation to be performed.

The iris recognition module compares the iris pattern of the user with the previously stored iris pattern, and authenticates the user who has accessed the door lock according to the comparison result. The micro controller controls the opening and closing of the door based on the user authentication result do.

On the other hand, when the battery voltage level of the battery unit for the iris recognition module falls below a predetermined level, the second switch for interrupting the power supply from the digital door lock battery unit to the iris recognition module is turned ON, And the iris recognition module supplies the iris power to the door lock battery so that the iris recognition module supplies power to the iris recognition module.

Thus, the battery replacement timing can be matched, and the battery of the digital door lock can be efficiently managed and operated.
