Description

Door Lock Enabling for Identifing User}

The present invention relates to a door lock that can be identified by a user. More specifically, the present invention relates to a door lock capable of identifying a user who knows who is trying to open or close the door lock by generating sound source data in which melody sound or voice is data.

In the past, mechanical door locks, which use metal keys to open and close doors, have been mainly used as door opening and closing devices for offices, hotel rooms and apartments. However, the conventional mechanical door lock has a weak security because the metal key, which is an opening and closing means of the lock, is vulnerable to loss and duplication. In recent years, in consideration of the weakness of the conventional mechanical door lock, the door lock to open and close the door using an electronic key including a magnet card method or a smart card method, a door lock that can be opened and closed by entering a password. A variety of products are being used, and furthermore, door locks that can be opened and closed through biometrics using uniqueness of specific parts of the human body such as voice recognition, fingerprint recognition, and face recognition have been actively studied and put into practical use.

Conventional door locks commonly use electronic keys, passwords and biometric information as authentication means for door locks. Here, the electronic key means any one door lock opening and closing means of a predetermined door lock opening and closing means including a magnetic card method and a smart card method in which an IC chip is embedded.

In the conventional door lock, an electronic key authentication method for authenticating an electronic key performs authentication on an electronic key input to a button key input unit. In addition, authentication of the door lock may be performed by inputting a password into the door lock separately from using an electronic key. That is, the door lock is provided with a button key input unit. Since the button key input unit is provided with the '#' key and the '*' key as well as the numeric keys of 0 to 9, the user can operate the button key provided in the button key input unit. The door lock is opened and closed by entering a password through. On the other hand, biometric information that is more secure than electronic keys, i.e., a person's biological and behavioral characteristics, such as a fingerprint, a face, a palm print, a retina, an iris, and the like may be used as an opening / closing means of a door lock.

However, the conventional door lock has informed the success or failure of the door lock opening and closing only by blinking the alarm sound and / or the light emitting diode in the process of attempting to open and close the door lock. Therefore, there is a problem that the user in the room does not know who is attempting to open or close the door lock only by the simple alarm sound and / or the blinking of the light emitting diode generated in the door lock.

Furthermore, if there is a user attempting to open or close the door lock at night, the user in the room must check out the entrance of the door or operate the so-called door phone to check the identity of the person attempting to open or close the door. There was a disadvantage.

In order to solve the above-mentioned problems, the present invention is provided with sound data in which the melody sound and voice are data on the door lock, and allows the door lock user to specify a unique sound source data of each time to open and close the door lock. An object of the present invention is to provide a door lock capable of identifying a user in which unique sound source data for each user is generated.

In addition, the present invention provides a door lock that can be identified by the user, the object of the night is to adjust the size of the sound source data to prevent unnecessary noise in the surroundings.

1 is a block diagram showing an internal configuration of a door lock capable of user identification according to a preferred embodiment of the present invention.

The user lockable door lock 100 according to an exemplary embodiment of the present invention includes a button key input unit 102, an electronic key sensor unit 104, an authentication unit 106, a memory unit 108, and a controller unit 110. , A driving unit 112, a sound source controller unit 114, a sound source data storage unit 116, an output unit 118, a manual lock operation unit 120, and a power supply unit 122.

In the present invention, the electronic key means any one of a door lock 100 opening and closing means including a magnetic card key and a smart card in which an IC chip is embedded, and stores different detection authentication information for each electronic key. The detection authentication information is unique information different for each electronic key and includes storage authentication information of the door lock 100 that can be opened and closed with the corresponding electronic key, user personal information, and a serial code of sound source data designated by the user.

The button key input unit 102 includes a '#' key and a '*' key as well as numeric keys 0 to 9. The user may open and close the door lock 100 by inputting a password through a button key operation provided in the button key input unit 102.

The authentication unit 106 is composed of an MPU (MPU: Micro Processor Unit) carrying an authentication algorithm. When the user enters a password in the button key input unit 102 or contacts or approaches the electronic key to the electronic key sensor unit 104 to open or close the door lock 100, the authentication unit 106 performs an embedded authentication algorithm. By driving, it is checked whether the password input from the button key input unit 102 and the detection authentication information of the electronic key detected by the electronic key sensor unit 104 match the password or storage authentication information stored in the memory unit 108.

If the detection authentication information of the electronic key detected by the electronic key sensor unit 104 or the password input by the button key input unit 102 is justified, the authentication unit 106 generates an authentication success signal to generate the controller unit 110. To pass. On the contrary, if the aforementioned authentication information or password is not justified, the authentication unit 106 generates an authentication failure signal and transmits it to the controller unit 110.

The memory unit 108 is configured as a storage element of an EEPROM (Electrically Erasable Programmable Read Only Memory) type that is easy to read and write to store storage authentication information. The storage authentication information includes detection authentication information of an electronic key capable of opening and closing the door lock 100 and / or a password designated by the user in the button key input unit 102.

The controller unit 110 includes a microprocessor as a kind of central processing unit having serial and parallel ports, EPROM (Erasable Programmable Read Only Memory) or ROM in which an operating system program for driving the door lock 100 is stored. The controller 106 is connected to the authentication unit 106, the driving unit 112, the output unit 118, the manual locking operation unit 120, and the power supply unit 122.

The controller 110 controls the driving of the door lock 100 based on the authentication success signal or the authentication failure signal transmitted from the authentication unit 106. When the controller unit 110 receives the authentication success signal from the authentication unit 106, the controller unit 110 generates a driving success signal and transmits the signal to the driving unit 112 and the output unit 118, and the authentication unit 106 transmits the authentication failure signal. When received, a driving failure signal is generated and transmitted to the output unit 118.

The driver 112 includes one or more relay driving devices, solenoid driving devices, servo motors, mortis, and the like. When the driving unit 112 receives the driving success signal from the controller unit 110, the driver 112 drives a load including the servo motor and the mortis to unlock or lock the door lock 100.

The sound source controller 114 includes a microprocessor unit (MPU) as a control device for controlling the sound source data storage 116 and the output unit 118. The sound source controller 114 analyzes the driving success signal transmitted from the controller 110 to search sound source data corresponding to the serial code of the user-specific sound source data in the sound source data storage unit 116 and output the output unit 118. To pass. If the serial code of the user-specific sound source data is designated in the silent mode, the sound source controller 114 may control the volume level of the sound source so as not to generate unnecessary noise in the surroundings.

In addition, since the user may set the time through the sound source controller 114, it is possible to adjust the volume of the sound source generated during the day and night. That is, the MPU of the sound source control unit 114 includes a clock circuit and sets a time in the clock circuit. Therefore, the sound source controller 114 operates in a state in which the silent mode or the volume is weakly adjusted so as not to generate noise by generating unnecessary sound sources in the surroundings after sunset.

The sound source data storage unit 116 is configured as an EEPROM-type storage element that is easy to read and write, and stores the digitally sounded source data by sampling a melody sound or a voice such as "Please input the electronic key again." Doing. The sound source data described above includes a unique serial code that is different for each electronic key. The serial code is a distinguisher that distinguishes user-specific sound source data by assigning flag values (eg, 0, 1, 2, ...) to the sound source data, respectively. In addition, a time field and a volume generation size field of sound source data may be added to the serial code.

Therefore, when the user stores the serial code of the sound source data in the electronic key, the user-specific sound source data is reproduced through the output unit 118 when the electronic key authentication is successful. For example, if a family has four people, the melody that occurs when the father's key is activated and authenticated to the door lock is set to "Spring of Home", and the mother is "Mother Grace". In the case of "Mazinga Z" and in the case of the daughter "school paper polka dots" and set to set, the members of the house can tell the key users who only hear the melody of the generated song.

In addition, when there is a user entering and exiting at a late time, the volume of the sound source data generated from the door lock 100 may be operated in a weak or silent mode to control the generation of unnecessary noise in the surroundings.

For example, since the controller 110 includes a clock circuit, the controller 110 may set a predetermined time (for example, from 21 o'clock to 6 o'clock the next day) in the door lock when the predetermined time is reached. It can be designed so that the volume generated is automatically reduced to 1/2 or 1/3 of the basic volume. In more detail, by configuring a type of deep-switch in the controller unit 110 described above, when a user sets a time by operating a deep-switch, the set time is set. Volume is adjusted. In addition, a manufacturer may include a program that sets a time zone for reducing silence or volume in the clock circuit of the controller unit 110 by using the usage statistics obtained by statistically quantifying the time slots during which the user opens and closes the door lock 100 during the day. It may be.

The output unit 118 includes an audio output device such as a speaker, an image output device such as a light emitting diode (LED), and a door phone connection terminal. When the authentication of the electronic key is successful, the output unit 118 flashes a light emitting diode (LED) and the sound of the sound melody or sound source data in which the sound is data is stored, such as a speaker provided inside the door lock 100. Playback is performed with a separate door phone (not shown) connected to the output element and / or door phone connection terminal. On the contrary, if the authentication for the electronic key fails, the light emitting diode (LED) flashes and the sound source data including the melody sound or the voice data such as "Please re-enter the electronic key" is stored inside the door lock 100. Playback is performed by a separate door phone (not shown) connected to a sound output device such as a speaker provided in the door phone and / or a door phone connection terminal.

The manual lock operation unit 120 refers to a device for manually setting and unlocking the door lock 100. The user in the room is used to set the lock and unlock setting of the door lock 100 to open and close the door.

The power supply unit 122 includes an internal power source using a battery and / or an external power source using a commercial power source. The power supply unit 122 supplies the power for operating the door lock 100 to the authentication unit 106, the driving unit 112, the output unit 118, and the manual lock operation unit 120 through the controller unit 110. do.

Figure 2 is a block diagram simply showing the internal configuration of the electronic key that is the opening and closing means of the user lockable door lock according to an embodiment of the present invention.

The detection authentication information is unique information that is different for each electronic key 200, and includes authentication information of a door lock 100 that can be opened and closed by the electronic key 200, user information, and a serial code of sound source data designated by a user. do. When the user touches or approaches the electronic key 200 to the electronic key sensor unit 104, the detection authentication information stored in the authentication information storage unit 202 is transmitted to the electronic key sensor unit 104.

The interface unit 204 is configured as one of an RF type contactless sensor and a magnet type contact sensor, and transmits detection authentication information stored in the authentication information storage unit 202 to the electronic key sensor unit 204.

The electronic key control unit 206 is a control device for controlling operations of the authentication information storage unit 202 and the interface unit 204 and includes an MPU (MPU) and an encryption algorithm. The encryption algorithm encrypts the detection authentication information stored in the authentication information storage unit 202 using a floating ID method. The electronic key controller 206 encrypts the authentication information using an encryption algorithm and stores the authentication information in the authentication information storage unit 202. Since the variable encryption scheme is described in detail in the Patent No. 307665 Patent Applicant filed by the present applicant, the description thereof will be omitted.

Let (S300). The electronic key sensor 104 senses the detected authentication information stored in the authentication information storage unit 202 of the electronic key 200 and transmits the detected authentication information to the authentication unit 106 (S302).

The authentication unit 106 compares the stored authentication information stored in the memory unit 108 of the door lock 100 with the detection authentication information of the electronic key 200 sensed by the electronic key sensor unit 104, and the corresponding electronic key 200. Check whether it is right (S304). If it is determined in step S304 that the electronic key 200 is legitimate, the authentication unit 106 generates an authentication success signal and transmits it to the controller unit 110 (S306). The controller 110 receiving the authentication success signal generates a driving success signal and transmits the generated signal to the driver 112 and the sound source controller 114 (S308). This drive success signal also includes the serial code of the sound source data.

The driver 112 receiving the driving success signal drives the mortis to release the door lock 100, and the sound source controller 114 matches the user's unique sound source data that matches the serial code of the sound source data included in the driving success signal.

Since the sound source controller 114 controls the volume level of the sound source data generated through the output unit 118 based on the time set in the MPU, the volume of the sound source data generated during the day and night may be different from each other. That is, when there is a user who enters at night, the sound source controller 114 operates in the silent mode in which sound source data does not occur, and weakly generates the volume of the sound source data to prevent the generation of unnecessary noise in the surroundings.

On the other hand, if the authentication unit 106 compares the detection authentication information of the electronic key 200 and the stored authentication information of the door lock 100 in step S304 and determines that it is not right, it generates an authentication failure signal and generates the controller unit 110. The controller 110 receives the authentication failure signal and generates a driving failure signal, and transmits the generated drive failure signal to the sound source controller 114 (S314).

The sound source controller 114 receiving the driving failure signal transmits the sound source data including the voice data such as "Please input the electronic key again" from the sound source data stored in the sound source data storage unit 116 to the output unit 118. To pass.
