The sign displayed on the touch pad 110 may be formed in a color different from the background color of the touch pad 110, or may be formed of a light-transmissive material on the ground having light shielding properties (or vice versa). It may be formed.

The capacitive sensor 120 is formed of at least one electrode, and when the user's finger approaches or contacts the electrode, the capacitance changes between the user finger and the electrode. In addition, the signal processor to be described later detects the amount of change, thereby determining the approach or contact of the user's finger. The capacitive sensor 120 is disposed on the back side of the touch pad 110 corresponding to the positions marked with the respective marks. In such a configuration, the user can perform the desired input only by touching the finger at the position (contact point) of the desired code.

That is, display is performed by making the meaning of at least one check result correspond to each code of the touch pad 110, and making the light emitting element 210 of that code flash. Such display can also be performed by flashing a single sign, and can be variously displayed by simultaneous blinking or blinking of light emitting elements 210 in a horizontal column or a vertical column.

Meanwhile, the memory unit 500 added in the second embodiment is a volatile or nonvolatile memory, and allows the controller 300 to freely store and read information. Of course, information that is not accessible to the controller 300 may be stored.

In such a memory unit 500, a password is mainly stored for releasing the security of the door lock system.

On the other hand, in the case of registering a password in the memory unit 500 by the user's input, the control unit 300 receives a series of codes to be registered as a password, the light emitting drive unit so that the input code can flash sequentially Control 220. When the user who confirms the flashing codes confirms that the input is made correctly and performs an input indicating the completion of the input, the controller 300 stores the input codes as a new password in the memory unit 500.

FIG. 5 is a flowchart showing a password registration procedure in the door lock system according to the second embodiment having such a configuration, and FIG. 6 is a flowchart showing a function checking procedure performed in this system.

First, a password registration procedure will be described with reference to FIG. 5. When adding a new password or changing an existing password to the door lock system, the user performs an operation according to a predetermined procedure, in which the control unit 300 executes a function of registering a new password (S21).

After that, the user enters a code to be used as a password (S22). The controller 300 determines whether an input code is an input for a code to be used as a password or input indicating completion of an input for constituting a password using the codes input so far (S23). At this time, if it is determined that the input code is the input of the code to be used as a password, the input code is temporarily stored in a predetermined buffer (not shown) (S24). The process then returns to step S22 to obtain subsequent input. On the other hand, if it is determined in step S23 that the input code is the input indicating the completion of the password input, the control so as to blink the input code so far in the input order (S25). That is, the light emitting control signal outputs a light emission control signal for turning on or off, changing the brightness or the color of the numbers input by the controller 300 in the input order.

Thereafter, when the user re-confirms the code displayed sequentially flashing as described above, and confirms that the password is the same as the intended password, the user performs an input for confirming that the password has been correctly input (S26), and the control unit 300 is stored in the buffer. A series of codes are registered and stored in the memory unit 500 as a new password (S27).

Next, with reference to Figure 6, the function check procedure for the door lock system will be described. In FIG. 6, an operation check for the door lock function unit 400 is described in the door lock system. However, the present disclosure is not limited thereto, and the memory unit 500, the touch function unit 100, or the light emission function unit 200 may be described. All parts such as) can be checked.

In order to check whether at least the dead bolt 410 is currently maintained in the door lock function unit 400 or whether the dead bolt driver 420 can operate normally, the control unit 300 performs a function check. The door lock control signal is output to the door lock function unit 400 (S31).

Then, the door lock function unit 400 performs self-inspection, and outputs the information indicating the inspection result to the control unit 300 as an inspection signal. The control unit 300 receives the check signal (S32), and checks the result of the check included in the check signal. In operation S33, the light emission control signal is output to flash one or more light emitting elements 210 of the touch pad 110.

By this display function, the user can conveniently and easily check the light emitting elements 210 which blink the state of the door lock.

According to this figure, the door lock system further comprises an electronic key recognition unit 600 in the door lock system according to the second embodiment, the description of the same components will be omitted.

The electronic key recognition unit 600, which is an added component in the present embodiment, reads and obtains the individual authentication information when the electronic key storing the individual authentication information comes into contact or access. The obtained individual authentication information is output to the control unit 300 to perform subsequent authentication procedures. Such an electronic key may be an RFID device, a magnetic card, a smart card, or the like.

On the other hand, in order to realize the third embodiment, the memory unit 500 must further store verification information which is information for authenticating the individual authentication information in advance.

When the user obtains individual authentication information stored in the electronic key from the electronic key recognition unit 600 by contacting or accessing the electronic key to the electronic key recognition unit 600, and outputs it to the control unit 300, the control unit 300 stores the memory. The verification information stored in the unit 500 is read out, and authentication processing between the verification information and the individual authentication information is performed. The control unit 300 controls the driving of the dead bolt 410 by controlling the door lock function unit 400 according to whether the authentication is successful.

On the other hand, in the door lock system for performing such an operation, a plurality of electronic keys can be registered and used. Therefore, the user of the door lock system needs to know the number of electronic keys registered to date.

To this end, the control unit 300 further includes a function of displaying the number of electronic keys that are currently registered according to a request of a new electronic key or a user. That is, the number of registered electronic keys can be displayed by a method of flashing a corresponding number among the signs displayed on the touch pad 110, or by flashing any number of codes corresponding to the number of electronic keys. .

First, the user executes a function such as registering a new electronic key or re-registering a previously registered electronic key by a predetermined input (S41). Thereafter, the user contacts the electronic key to be registered with the electronic key recognition unit 600 (S42), and the control unit 300 reads out individual authentication information from the contacted electronic key and stores the verification information in the memory unit 500 as verification information. (S43). The controller 300 checks the number of existing verification information stored in the memory unit 500, and displays the number by flashing the corresponding number of the touch pad 110 or by using the number of flashing codes. It is displayed (S44).

According to this configuration, it is possible to easily grasp the existence of an invalid user who illegally registers and uses the electronic key.

(Example 4)

Next, a touch pad device according to a fourth embodiment of the present invention will be described. In the fourth embodiment, a touchpad device applicable to all configurations of the first to third embodiments described above is disclosed. That is, when the user touches the surface of the touch pad 110, the touch panel 110 has a function of recognizing a plurality of contact points at the same time or sliding contact as separate input signals, wherein the light emitting devices of the contact points at which each contact is made A touch pad device that blinks 210 is disclosed.

Such a touch pad device will be described using the touch pad device of the first embodiment as an example. Therefore, components and functions already described in the first embodiment will be omitted and only differentiated contents will be described.

First, in the touch function unit 100, the signal processor 130 includes a register (not shown) having bits corresponding to each touch point of the touch pad 110. Then, at a predetermined inspection time (for example, 10 ms), a change in capacitance at each touch point of the touch pad is sensed, and a bit corresponding to the touch point at which the capacitance changes is set. The register value is output as a serial signal to the control unit 300. After the output of the serial signal, the values in the registers are reset.

The controller 300 receives a serial signal output from the signal processor 130 and determines a contact point where a user's contact has occurred. The control unit 300 measures a predetermined reference time (for example, 100 ms) and determines how many inputs have occurred during this reference time.

At this time, if only an input for one sign is generated during the reference time, it is determined that the user has made an input for a number or symbol displayed on the contact point. On the other hand, if it is determined that the user's contact with at least two or more contact points occurred during the reference time, the user is considered to have inputted an additional function, not a sign input.

Here, the user's contact with at least two or more contact points during the reference time is in a multi-input operation or state in which the user makes a wide contact such that the user touches a finger or a palm simultaneously with a plurality of contact points of the touch pad 110. This is caused by a sliding input operation that slides and sweeps down.

That is, if the user makes an accurate contact with one contact point, the signal processor 130 considers that one number is desired to be input. If the user makes a contact with a contact point wide or sweeps down, the signal is different from the number input. The function is considered to be entered.

Meanwhile, as an example of the additional function, when the touch pad device according to an embodiment of the present invention is applied to a device such as a digital door lock, the touch pad device may be turned on / off, the sleep mode is switched to the wake-up mode, and the password is provided. Start or end of input, entry into various function setting menus, or confirmation of a set function.

In the touch pad device having such a configuration, the controller 300 performs control of blinking the light emitting element 210 disposed at the contact point whenever the user contacts the touch pad 110.

That is, when a user's contact is generated and the signal processor 130 outputs a serial signal, the controller 300 slides or touches the touch pad 110 to determine whether the contact is for inputting a general number or symbol. It detects whether it is a contact for inputting an additional function and outputs a signal corresponding thereto. At the same time, if it is determined that the user contact is for inputting a code, the controller 300 controls the light emission driver 220 to blink the light emitting element 210 at the contact point corresponding to the code. In addition, when it is determined that the user's contact is an input of the additional function, the light emission driver 220 is controlled such that one or more light emitting elements 210 designated for the additional function blink according to a predetermined rule.

In addition, in the door lock system, when user authentication by a password or an electronic key fails more than a predetermined number of times, the door lock system stops all functions for a predetermined time after locking the dead bolt 410. . In other words, the door lock system is locked in a locked state. At this time, the time when the operation is resumed, the elapsed time or the remaining time of the predetermined time is displayed by flashing one or more symbols of the touch pad 110. This may be displayed by flashing a code such as a number disposed on the touch pad 110 or by a combination of a plurality of light emitting elements 210. This feature allows the user to see how long they have to wait.

In addition, when the door lock system is locked by the internal forced lock function by the internal forced lock switch provided in the indoor device, a specific code or a plurality of codes of the touch pad 110 may be displayed by blinking. The general door lock system provides a forced lock function for preventing the dead bolt 410 from being released by a valid password or an electronic key from the outside, and this function is provided by an internal forced lock switch (located in an indoor device of the door lock system). Not shown).

On the other hand, the setting of such a forced lock function could not be confirmed in the outdoor device of the door lock system. Therefore, in this embodiment of the present invention, when such a forced lock is set, by causing the plurality of light emitting elements 210 of the touch pad 110 to blink, an external user can easily check the current state of the door lock system. do.

In this way, as can be seen through various embodiments, by using the touch pad device according to the present invention, it is possible to display the current state of the door lock, the setting state of the operable functions, the presence or absence of failure of the door lock in various ways do. Therefore, even in the outdoor side device of the door lock which does not have a separate external display means, the state of the door lock can be easily confirmed.
