The present invention relates to a door lock system having a separation detection function, and more particularly, in a door lock system in which a digital door lock and an input body are separated, a door lock which detects that the input body is separated from the system to prevent release of the system. It is about the system.

The door lock system installed at the door of a house, etc., can operate a dead bolt on the door to arrange a digital door lock for locking or unlocking the door, and the user can attempt to authenticate the user by entering a password or touching / accessing an electronic key. The input main body is evolving to be installed on the wall near the door.

On the other hand, the input main body in such a door lock system is mostly configured to be fixed after being inserted into the groove installed on the wall, the input main body is fixed by being fastened from the outside using a screw or the like after being inserted into the groove of the wall. Further, in order to facilitate the installation of the input main body, it may be attached and fixed to the wall surface where the groove is not formed by a screw or the like.

In this simple structure, the input body installed on the wall is very likely to be stolen, and the stolen body may be connected to any digital door lock and reused.

In order to prevent such theft, the conventional door lock system is configured such that the wire is disconnected when the input main body is separated from the wall surface, and a theft alarm is issued when the wire is disconnected.

However, in such a configuration, there may be a play that separates from the wall without disconnecting the wire, and there is a possibility that the play may be electrically or mechanically operated to block an alarm by damaging the input body.

The present invention is to solve the above-described problem, in the door lock system of the input main body and the digital door lock is separated, the object is to accurately detect the situation that the input main body is separated from the wall or the like.

In addition, when the input main body is separated from the wall, the input main body cannot be operated, and moreover, the separated input main body can not be operated even when it is connected with another digital door lock.

Furthermore, even in a situation where the digital door lock is separated from the door, it provides a security enhanced processing method.

According to an aspect of the present invention, there is provided a door lock system including an input main body installed on an outer wall near a door and a digital door lock that locks or unlocks the door according to control of the input main body. A sensing unit configured to output a first signal when the input main body is completely attached to the wall and to output a second signal when separated from the wall; An authentication information input unit configured to receive authentication information from a user; A first memory for storing confirmation information for authenticating the received authentication information; While the sensing unit is outputting the first signal, the received authentication information is output to the digital door lock side together with the confirmation information stored in the first memory. When the sensing unit outputs the second signal, the operation of the authentication information input unit is blocked. In addition, when the sensing unit outputs the first signal after the second signal, requesting the digital door lock to provide the stored confirmation information, and comparing the confirmation information provided from the digital door lock with the confirmation information stored in the first memory. And a first control unit for controlling an operation of the authentication information input unit, wherein the digital door lock comprises: a dead bolt driving unit driving a dead bolt to lock or unlock a door; A second memory for storing the confirmation information; When the authentication information and the confirmation information are input from the first control unit, both the comparison is performed and the operation of the dead bolt driving unit is controlled according to the match, and the confirmation stored in the second memory according to the request of the first control unit. And a second control unit for providing information.

The sensing unit may be a switch that is turned on or off depending on whether the main body is completely mounted on the wall surface of the main body.

The first control unit may block the operation of the authentication information input unit and request the second control unit to switch the door to a locked state.

In addition, the input body is installed on one side of the door, it is characterized in that the digital door lock is configured as a separate or integral.

According to the door lock system having a separation detection function according to the present invention having the configuration as described above, it accurately detects that a situation in which the input main body is separated by an illegal user from the wall, etc., and immediately blocks the operation of the input main body. . In this way, it is possible to cut off the operation of unintentionally unlocking the system by separating the input main body.

In addition, even if an input body separated from a system is connected to another digital door lock to form a door lock system, the input body is blocked from operation. As a result, it is possible to prevent reuse of the separated input body.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the present invention.

FIG. 1 is a view illustrating a door lock system in which an input main body and a digital door lock are separated so as to interlock with a door.

The input main body is installed near the door, and a keypad having a plurality of keys for the user to manually input a password, and secure data from the electronic key when the electronic key, which has a predetermined security data, is touched or accessed. Wired and wireless communication means for receiving, a scanner for scanning the user's fingerprint, a camera for photographing the user's face is provided. Hereinafter, password, security data, fingerprint form information, and face form information are described as authentication information.

On the other hand, the input main body maintains confirmation information for processing user authentication in comparison with authentication information input by the user. In general, the authentication information and the confirmation information may be (substantially) the same information.

When the input main body receives authentication information from a user who attempts to authenticate, the input main body transmits the input authentication information and previously held confirmation information to the digital door lock side. Thus, the actual authentication process can be done in the digital door lock .

In addition, the input body according to the invention is configured such that its operation is limited when it is separated from the wall surface or from the door lock system. This will be described in detail below.

The digital door lock is provided on the door and has a dead bolt which makes the door locked or opened by protruding / retracting from the door (of course, the digital door lock is installed in the door frame and the dead bolt protrudes / retracts toward the door). Is also possible).

The digital door lock drives the dead bolts forward to lock the door or retracts the dead bolts according to the success or failure of the authentication process using the authentication information and confirmation information transmitted from the input main body or according to the input lock signal or unlocking signal. To keep the door open.

The wall pad is mainly installed indoors and connected to the input main body to control the operation. In addition, it is possible to provide voice / image communication with a user approaching the input main body. In addition, the wall pad may also be connected to the digital door lock to output the lock signal or the unlock signal to the digital door lock. The wall pad may communicate with a remote security center to report the operational status of the wall pad, input body and digital door lock.

2 is a block diagram showing the configuration of a door lock system having a separation detection function according to the present invention. According to the drawing, the door lock system may include an input body 10 and a digital door lock 20.

The input main body 10 includes a sensing unit 12, an authentication information input unit 14, a first memory 16, and a first control unit 18, and the digital door lock 20 includes a dead bolt driver 22. And a second memory 24 and a second control unit 26.

The sensing unit 12 of the input main body 10 detects whether the input main body 10 is completely mounted on or detached from the wall. That is, the sensing unit 12 has a micro switch 13 (see FIG. 3) which is turned on or off as it is pressed or released, and the micro switch 13 is provided when the input main body 10 is completely mounted on the wall. It can be configured to be pressed at and released at the moment the input body 10 is separated from the wall by more than a predetermined interval.

The sensing unit 12 may output a first signal when the micro switch 13 is pressed and turned on, and output a second signal when it is sensed that the micro switch 13 is released and turned off. The signal output from the sensing unit 12 is input to the first control unit 18. The first signal and the second signal output from the micro switch may be set in reverse with respect to the pressing and releasing of the switch.

Meanwhile, the sensing unit 12 may include a plurality of micro switches. In this case, the micro-switches may be installed in series to detect that the input main body 10 is separated even when at least one micro switch is turned off. It is desirable to.

The authentication information input unit 14 is secured from an electronic key by a keypad provided with a plurality of keys marked with numbers, letters, or symbols, by short-range wireless communication such as RFID communication, or by wired communication through direct contact through an electrical contact. Communication means for receiving a message.

The first memory 16 stores confirmation information which is information for authenticating authentication information such as a password manually input by a user through a keypad and security data input from an electronic key.

While the sensing unit 12 outputs the first signal, the first control unit 18 considers that the input main body 10 is completely mounted on the wall and is in safe operation, and operates each part of the input main body 10 normally. . When the user inputs the authentication information during this operation, the received authentication information is transmitted to the digital door lock side together with the confirmation information stored in the first memory 16.

In this case, if the sensing unit 12 outputs the second signal, the first control unit 18 considers that the input main body 10 is separated from the wall and blocks the operation of each unit constituting the input main body 10. In particular, it is preferable to block the attempt of the user authentication process by blocking the operation of the authentication information input unit 14.

On the other hand, when the first control unit 18 receives the second signal from the sensing unit 12 and receives the first signal while blocking the operation, the first control unit 18 is separated from the door lock system and then another door lock. It is assumed that it is configured as part of the system to start normal operation, and a procedure for confirming that the normal door lock system is configured is performed.

That is, the input main body 10 according to the present invention is implemented to operate normally only when the registered digital door lock 20 is connected when the system is initially configured. Alternatively, after the input main body 10 is connected to the other door lock system from the first door lock system, it may be implemented to operate normally after the correct authentication information is input.

For such a connection confirmation process, input the first controller 18 is a digital door lock (more specifically, digital door lock the second control unit of) its transmission of the confirmation information and maintain the second memory 24 of the main body 10 Ask. When receiving confirmation information from the digital door lock 20, the confirmation information from the digital door lock is compared with the confirmation information stored in the first memory of the input main body. As a result of the comparison, when both of them coincide with each other, the input main body 10 initially constitutes a door lock system and is considered to be combined with a normally registered digital door lock 20, so that each part of the input main body 10 can be normally operated. Set it.

On the other hand, as a result of the comparison, if the two do not coincide with each other, it is regarded that the input main body 10 is separated from the first registered door lock system, and is illegally coupled to another door lock system, and the operation of each part of the input main body 10 is performed. Keep blocked.

If the user wants to separate the input main body 10 from the first registered system and connect it to another new door lock system, delete the existing confirmation information set in the input main body 10 or register a new digital door lock. In this case, security management by additional user authentication process should be provided.

This connection confirmation procedure is performed when the input main body 10 is connected to the door lock system for the first time, that is, when the user inputs the input main body 10 purchased to the door for the first time or when the user moves the housing or the digital door lock. It can be executed when a new different digital door lock is connected by the troubleshooting of 20.

3 is a view for conceptually explaining a structure in which the input main body is mounted on the outer wall near the door as a door lock system having such a configuration. FIG. 3 is a vertically cut wall, in which an input main body 10 is inserted into a wall, and a power line, a data communication line, and the like extending from the input main body 10 pass through the wall to allow the digital door lock 20 or wall pad. The groove is formed to be connected to the.

Meanwhile, referring to FIG. 3, it can be seen that a part of the micro switch 13 is exposed from the input main body toward the wall surface. The micro switch 13 is configured to be pressed when the input main body 10 is securely mounted in the groove, and conversely, to be released when the input main body 10 is separated from the groove at all.

The micro switch 13 is not only a push switch as shown, but also a pair of light-emitting / receiving elements using light reflected from the wall, a contact for detecting an electrical connection between the input body and the wall, and an approach of the input body and the wall. Various methods may be applied, such as a metal electrode for sensing a change in capacitance, and a magnetic pole installed to change a magnetic force according to the approach of the input body and the wall.

Next, the structure of the digital door lock 20 will be described. First, the dead bolt driving unit 22 protrudes (advances) the dead bolt 21 from the door or inserts (retracts) the door into the door. The dead bolt driver 22 advances / retracts the dead bolt 21 by the rotation of a gear, a solenoid, or the like, and may be controlled according to the direction in which the driving voltage is applied.

When the input main body 10 is connected to the digital door lock 20, the second memory 24 checks whether the input main body 10 registered together at the time of the first configuration of the door lock system is connected again or in another door lock system. Confirmation information for use in determining whether the input main body is connected is stored. This confirmation information is stored after the digital door lock 20 forms the door lock system together with the input main body 10 and applied to the door, and then provided by the input main body 10 when the user registers a password or electronic key for the first time. It is.

When receiving the authentication information and confirmation information from the input main body 10, the 2nd control part 26 compares both. As a result of the comparison, if both are the same, it is determined that the user authentication has been attempted by a legitimate user, and the dead bolt driving unit 22 is controlled to open the door, and if the transmitted authentication information and the confirmation information do not coincide with each other, Determination is made by the user's approach, and the dead bolt driver 22 keeps the door locked.

In addition, when the second control unit 26 receives a request for transmission of the confirmation information from the first control unit 18, the second control unit 26 reads the confirmation information stored in the second memory 24 and provides it to the first control unit 18.

According to the door lock system having a separation detection function according to the present invention configured as described above, since the illegal state of separation between the input main body and the wall surface can be detected by the micro-switch, compared to the conventional method using a wire, Minimize undetected space. In addition, even if the input main body separated from the wall and separated from the door lock system is connected to another door lock system, if the authentication information is not known, the input main body cannot be used normally, thereby preventing unauthorized reuse of the stolen input main body.

Next, in the door lock system having a separation detection function according to the present invention, the separation detection operation of the input body and the reuse blocking procedure of the input body will be described with reference to FIGS. 4 and 5.

4 is a flowchart illustrating determination of normal operation and separation detection operation of the door lock system according to the present invention. First, when the input main body is normally connected in the door lock system and power is input, the input main body starts operation (S11).

The input main body senses a signal output from the sensing unit and determines whether it is a first signal or a second signal (S12). If the first signal is input, it is assumed that the input main body is connected to the normal (first registered with the digital door lock) door lock system and is normally mounted on the wall, and waits for authentication attempt by the user while operating all functions normally ( S13, S14).

On the other hand, if the second signal is input, it is assumed that the input body is separated from the wall (S16), the input body is to block at least some functions, in particular, the operation of the authentication information input unit is blocked (S16). Meanwhile, even when the input main body is separated from the wall and the micro switch is released, the wire for wired communication between the input main body and the digital door lock and / or the wall pad may still be connected. Therefore, the input main body can immediately output the lock signal to the digital door lock at the moment when the disconnection state is detected by the micro switch.

On the other hand, the input main body can report the separation of the input main body even with a wall pad, and the wall pad outputs an alarm by itself to warn that the input main body is about to be separated, or by outputting an alarm to a remote security center or the like. You may also be notified of the theft attempt.

5 is a flowchart illustrating a function of blocking a case where an input main body is separated from a wall and separated from a door lock system, and then connected to another door lock system to be reused.

That is, the input main body allows or blocks the operation of the user authentication unit at least according to the on / off of the micro switch. If the input main body is connected to another door lock system and mounted on the wall, the micro switch is turned on to output the first signal. The first control unit may release the blocking of the user authentication unit. Thus, a method for blocking such unauthorized reuse is described in FIG. 5.

In order to execute the reuse blocking procedure, the input main body and the digital door lock must maintain the same identification information (S21). In this way, the confirmation information is shared when the user first configures the door lock system by connecting the input body and the digital door lock (optionally, additional wall pads), and registers a password to be used in the future by operating the input body or the electronic key. It takes place in the process of registering. That is, when authentication information is first input to the input main body, the input main body stores the input authentication information as confirmation information in the first memory and transmits the authentication information to the digital door lock to store in the second memory.

After the input main body is normally mounted on the wall, authentication information is registered in the input main body, so that the sensing unit outputs a first signal according to the state of the micro switch, so that the second signal from the sensing unit is detected while the door lock system is operating normally (S22). If detected (S23), the input body detects that it is separated from the wall and at least blocks the operation of the user authentication unit (S24).

Thereafter, if the input main body is reinstalled in the door lock system and starts to operate, such as inputting power (S25), the input main body requests to provide confirmation information stored in the second memory upon initial registration for the connected digital door lock. When the confirmation information is transmitted from the digital door lock, the input main body compares the transmitted confirmation information with the confirmation information stored in the first memory (S26). As a result of the comparison, if the confirmation information of the input main body and the confirmation information of the digital door lock coincide, the input main body is separated from the door lock system (the system in which the input main body is normally connected and the authentication information has been registered) for the purpose of repairing a malfunction. Re-installed in the system can be regarded as allowing the normal operation of the input body (S27).

On the other hand, as a result of the comparison, if the confirmation information of the input main body and the confirmation information of the digital door lock do not coincide, it can be regarded that the input main body is stolen and used illegally by being mounted in another door lock system. It remains blocked, making it unusable.

The door lock system having a separation detection function according to the present invention described above has been described with reference to a separate door lock system in which the digital door lock and the input main body are separated from each other, but the present invention is not limited thereto.

For example, there may be a digital door lock system in which an input body through which a user can input authentication information, and a digital door lock having a dead bolt is integrated, and a component part of the input body or a part of the digital door lock is removed from the door. In order to detect the case of separation, a micro switch may be arranged between the component and the surface of the door.

In addition, when the input main body or the digital door lock is composed of a wall attachment portion and a plurality of slides or rotatable movable portions, the input body or the digital door lock may be modified and applied for the purpose of detecting an illegal deviation of the movable portion from the wall attachment portion.

According to this structure, even if a part of a digital door lock is isolate | separated from a door, it can monitor and respond.
