It is preferable that the connection cable 31 and the connection connector 30 for connection with the main body while being easy to carry by the user are attached to the housing of the main body as shown in FIG. 2. However, the connecting cable 31 and the connecting connector 30 can of course be attached to the portable unlocking device 5 as shown in FIG. 3.

The emergency unlocking system 1b is usually used in the system 1b so as to maintain a state where a failure does not occur in the case of being unable to release the locking device due to the failure of the main drive control system 1a. It is desirable to cut off the power supply to eliminate the failure factor.

The electronic door opening and closing apparatus 1 of the present invention includes an input keypad 205 for inputting a password, and enters a password into the keypad 205 to check a true user by comparing the password with a registered password to lock the door. An example of a password input method for releasing a device will be described.

However, the electronic door opening and closing apparatus 1 according to the present invention mainly operates the fingerprint input sensor 206a, the iris input sensor 206b, or the RF input sensor 206c as indicated by the dotted line in FIG. As the input means 206 of the drive control system 1a, a fingerprint input sensor 81a, an iris input sensor 81b, or an RF input sensor 81c is input to the portable unlocking device 5 correspondingly. The present invention can be applied by using as (81).

First, in the main drive control system 1a which normally operates the electronic door opening and closing device 1, the keypad 205 for inputting a password is connected to the input side of the microprocessor CPU 10, and the CPU 10 200 is connected. The switch side driving circuit 70 for operating the door lock is connected to the output side of the door. The CPU 10 200 is also connected with a normal memory device 204 for storing a password registered by the user and for authenticating the user when the system 1a is in a normal state. Of course, although not shown in the system 1a, a separate memory device for temporarily storing the system control program and the data under processing is provided.

In addition, the main drive control system 1a supplies the main power supply unit 201 for supplying + 5V VCC and + 12V VDD operation power to the system, and the operation power supply when the main power supply unit 201 is inoperable due to power failure or circuit failure. An emergency battery 202 is provided to provide the emergency battery 202, which is connected to the main power supply 201 of the main drive control system 1a or the connection cable 31 according to the setting of the changeover switch 203. It is possible to provide a + 9V EVDD operating power to the emergency unlocking system 1b through the connection connector 30 and the portable unlocking device 5.

In addition, the switch driving circuit 70 is connected to the power supply intermittent portion 40 for supplying the operating power required to operate the switch 71 by receiving the operating power of the main power supply unit 201.

The keypad 205 includes a number button for password input, various function buttons for inputting function codes such as number input, registration, deletion, and the like.

On the other hand, the main drive control system (1a), in addition to the above-described basic configuration, a well-known guidance LED, speaker, buzzer, LCD, door lock device necessary to confirm the authentication result or guide the procedure of information input between the user and the system It is preferable to have a lock sensor or the like for determining the current state of the present invention, but the illustration is omitted so that the description of the present invention can be easily understood.

In addition, the emergency unlocking system 1b is a small one-chip microprocessor (CPU1: 10) for system control and an emergency memory device 50 usable as a serial EEPROM for storing a user's registered password for user authentication in case of emergency. ), A memory input / output switching unit 60 for switching the input / output so that the CPU 10 (200) and the CPU 1 (10) can selectively access the emergency memory device (50), and is applied through the connection connector (30) A constant voltage unit 20 that provides stabilization power required for the system 1b by the operating power source of the emergency battery 202, and an emergency memory device 50 of the system 1b in accordance with the power source of the constant voltage unit 20; The power supply control unit 40 generates an emergency operation power source BVCC necessary for the operation of the memory input / output switching unit 60.

In addition, the portable unlocking device 5 is an emergency battery 202 when connected to the connecting connector 30 extending through the connecting cable 31 from the main body of the electronic door opening and closing device 1 as shown in Figs. The + 9V EVDD operating power is applied to the power supply unit 110 of the portable unlocking device 5 and at the same time the operating power supply EVDD for the emergency unlocking system 1b and the portable unlocking device 5 And a connection terminal unit 120 for forming a transmission / reception communication line (TX, RX) between the emergency unlocking system 1b.

In addition, the portable unlocking device 5 is provided with an input means 81 that is activated by the operating power applied from the power supply device 110 and corresponds to the input means 206 of the main body of the electronic door opening and closing apparatus 1. For example, when the keypad 80 is used as an input means, the input password is processed to be transmitted to the emergency unlocking system 1b, and the user authentication result inquired by the emergency unlocking system 1b is displayed on the LCD. And a one-chip microprocessor (CPU2: 100) for performing signal processing for display on 90).

In addition, the portable unlocking device 5 may be unlocked by operating the on / off power switch 5a instead of having an emergency battery in the system 1a or at the same time with the portable unlocking device 5. It is also possible to drive the device 5 and the emergency unlocking system 1b.

Meanwhile, the emergency lock release system 1b will be described in more detail. As shown in FIG. 2, the power supply intermittent part 40 is an emergency memory for registering a password in the emergency memory device 50 in the main drive control system 1a. SCR1 for generating emergency operation power (BVCC) required for the operation of the device 50 and the memory input / output switching unit 60 and the emergency unlocking system 1b to read the password registered in the emergency memory device 50 for emergency use. The SCR2 generates an emergency operation power source BVCC required for the operation of the memory device 50 and the memory input / output switching unit 60.

That is, the SCR2 is output only during the period in which the gate control signal BVON is applied from the CPU1 10 while the stabilization operation power source BVC of the constant voltage unit 20 is applied to the anode. The emergency operation power source BVCC necessary for the operation of the memory input / output switching unit 60 is instantaneously generated and applied. In addition, the SCR1 also has an emergency operating power source BVCC only when the gate control signal VON is applied from the CPU 10 200 in a state where the operating power source VCC of the main power supply unit 201 of the main drive control system 1a is applied to the anode. Occurs instantaneously.

In addition, the memory input / output switching unit 60 is composed of six gate switches 60a to 60f for storing and reading 3 bits of data to the emergency memory device 50, and three gate switches 60a and 60c, 60e) is a channel used by the CPU 10 200 to register a 3-bit password MD0-MD2 to the memory device. The three gate switches 60b, 60d, and 60f are stored in the memory device. Used to read a password.

The switch driving circuit 70 has a switch 71 commonly connected to the loads of the transistors Q1 and Q2, and the transistor Q1 is locked from the CPU 10 200 when the main drive control system 1a is in a normal state. When the open signal LOCKER OPEN for the device release is applied through the resistor R1, the transistor Q2 is operated to release the lock from the CPU1 10 when the main drive control system 1a is in an abnormal state. It is operated when the door open signal BMON is applied through the resistor R2.

In this case, the switch driving circuit 70 is supplied with the operating power supply VDD from the main power supply unit 201 through the diode D1 when the system 1a is in a normal state, and the emergency battery when the system 1a fails. A + 9V EVDD operating power of 202 is applied via diode D2. Here, the diode D3 is a protection diode for protecting the circuit from the instantaneous high voltage generated during the operation of the switch 71.

The password registration procedure of the electronic door opening and closing device according to the present invention configured as described above will be described with reference to FIG. 4.

First, in order to release the lock state in the event of failure of the electronic door opener 1, a password must be registered in advance in the electronic door opener. In the password registration procedure, when the first and second passwords are input to the keypad 205 while the system 1a is in the registration mode (S10 and S11), the CPU10 200 of the system 1a enters the first and second inputs. It is determined whether or not matched by matching the password (S12).

If the result of the determination is different, the process returns to step S10 to request re-entry, and if a match is found, first the password is stored in the normal memory device 205 (S13) and registered. At the same time, the CPU 10 200 registers the emergency memory device. In step S14, a registration request signal VON for registering a password is output.

The power supply intermitter 40 converts the operating power supply VCC to BVCC according to the application of the VON signal, and applies it to the memory input / output switching unit 60 and the emergency memory device 50 (S15). The 3-bit passwords MD0-MD2 are stored in the emergency memory device 50 through the turned-on gate switches 60a, 60c, 60e (S16). Thereafter, the memory input / output switching unit 60 and the emergency memory device 50 are turned off according to the blocking of the VON signal from the CPU 10 (S17).

As described above, the power supply intermittent portion 40, the memory input / output switching unit 60, and the emergency memory device 50 of the emergency unlocking system 1b are powered only for a period necessary to register a password and then turned off. By blocking the, the stability of the circuit to be used in case of failure is ensured.

Hereinafter, a procedure of releasing the locking device when a failure occurs in the electronic door opening and closing device according to the present invention will be described with reference to FIGS. 5A and 5B.

First, the user manually switches the switch 203 of the emergency battery 202 in the main body of the electronic door opening and closing device 1 to the emergency unlocking system 1b (S20).

Subsequently, when the connection connector 30 is coupled to the connection terminal 120 of the portable unlocking device 5 (S21), power is applied to the CPU 2 100 from the power supply device 110 of the portable unlocking device 5. The portable unlocking device 5 is activated.

At the same time, the operating power is also applied to the constant voltage unit 20 through the connection connector 30 to the emergency unlocking system 1b, so that the stabilizing operating power source BVC is generated from the constant voltage unit 20, and the CPU1 (10). As the operating power source BVC is applied to the reset circuit, the reset circuit is activated to activate the CPU 1 10 to activate the system 1b. That is, the password to be input from the portable unlocking device 5 waits (S22).

In this state, when the password registered in advance in the electronic door opening and closing device 1 is inputted to the keypad 80 of the unlocking device 5, the CPU2 100 reads the value input from the keypad and displays it on the LCD 90. . When the user confirms that the password inputted through the LCD 90 is correct and presses the enter key (S23), the CPU2 100 encrypts the password and releases the emergency lock system 1b through the TX communication line of the connection terminal 120. Is sent to the CPU1 (10) (S24).

The CPU 1 10 decrypts the received encryption password, stores it in RAM, generates a BVON signal for reading the password registered in the emergency memory device 50, and provides the same to the power supply control unit 40 (S25).

Accordingly, the SCR2 of the power supply control unit 40 outputs only during the period in which the gate control signal BVON is applied from the CPU1 10 while the stabilization operation power source BVC of the constant voltage unit 20 is applied to the anode. As a result, the emergency operation power source BVCC necessary for the operation of the emergency memory device 50 and the memory input / output switching unit 60 is instantaneously generated and applied (S26).

When the emergency memory device 50 and the memory input / output switching unit 60 are applied with the BVON signal, the password registered in the emergency memory device 50 controls the gate switches 60b, 60e, and 60f of the memory input / output switching unit 60. Via the data bus (SD0-SD2) is input to the CPU1 (10) (S27).

Therefore, the CPU 1 10 reads the registered password and compares it with the password received through the TX communication line immediately before (S28), and if it matches, generates a door open signal (BMON) to the switch driving circuit 70 (S29). At the same time, the password determination result is transmitted to the CPU2 100 of the portable unlocking device 5 via the RX communication line and displayed on the LCD 90 so that the user can know the authentication result.

The switch driving circuit 70 releases the lock by the transistor Q2 is turned on according to the application of the door open signal BMON to operate the switch 71 (S30). As a result, the user can open the door by rotating the handle of the door.

However, if the registered password and the received password do not match as a result of the determination, the process returns to step S23 to request re-entry for a predetermined number of times.

In the above-described embodiment, the electronic door opening and closing device 1 illustrates an example of using a password as information for user authentication. However, the present invention may be applied to other types of user authentication methods in the same manner.

That is, when performing user authentication using the user's fingerprint as shown in FIG. 1, the master fingerprint of the master user is input through the fingerprint input pad of the fingerprint input sensor 206a instead of the keypad 205, and the feature points therefrom. And register the same to the normal memory device 204 and the emergency memory device 50 at the same time. Then, if a failure occurs in the system, the master user releases the lock through the emergency unlocking system 1b by inputting the master fingerprint to the fingerprint input sensor 81a of the portable unlocking device 5 in the same manner as described above. It becomes possible.

In addition, even when the iris input sensors 206b and 81b and the RF input sensors 206c and 81c of the well-known method are used, the locking device can be released through the emergency unlocking system 1b in the same manner. In particular, in the case of using the RF input sensor (206c, 81c) is different from the embodiment using the keypad 205, 80 is not directly input password through the keypad (205, 80) and the main drive control system and The only difference is that the password is transmitted wirelessly (RF) within a certain distance to the emergency unlock system.

1 and 2 illustrate an example in which only one user information input means 206 or 81 is used, but it is also possible to use the RF input sensors 206c and 81c in a combined manner for convenience of use. It is also possible to use a combination of one or more input means in order to increase security and usability.

In addition, it will be understood by those skilled in the art that the user information input means of the electronic door opening and closing apparatus to which the present invention is applied can be applied to voice recognition or any other method in addition to the above method.

Furthermore, in the above embodiment, in order to miniaturize the portable unlocking device, the portable unlocking device and the emergency battery for supplying the operating power to the emergency unlocking system are illustrated in the main body of the system. It is also possible to selectively provide the release device so that it can be used by operating the on / off power switch.

As described above, in the present invention, when a failure occurs such as an internal circuit or an input device in the electronic door opening and closing device, one of the operating power and the password / fingerprint / iris is used in the emergency unlocking system of the door opening and closing device using a portable unlocking device. By identifying the user can be realized quickly and simply unlock the electronic door opening and closing device.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
