A control unit which controls the screen output of the decoded input information, and a display unit which outputs the corresponding information according to the control of the central processing unit of the control unit; Unlike a general touch screen in which the pad and the display unit overlap each other in one area, the touch pad and the display unit are separated from each other so that the entire touch area of the touch pad can be used as an area for text input. It is characterized by.

An object of the present invention is to minimize the exposure of the number or alphabet used to enter the password by effectively removing the trace of the user remaining on the surface of the touch pad when the user enters the password into the door lock having a touch pad. .

In addition, another object of the present invention is to relieve the trouble of having to press the start and end keys or other symbols separately before and after the input in order to input the password.

In order to achieve the above object, a first aspect of the present invention is a door opening and closing operation unit for opening and closing a door according to a password input as a password input device using a touch pad. A second aspect of the present invention for achieving the object of the present invention is a password input method using a touch pad, the first step of generating a password input start event, when a password input start event occurs, touch the input point of the touch pad A second step of displaying on the pad, a third step of detecting an input point input through the touch pad, a fourth step of mapping the detected input point to a preset password, and a preset password to match the detected input point And a fifth step of instructing the opening operation of the door opening and closing operation unit.

In addition, the use of specially coated tempered glass and LED method to leave no trace of the user.

According to an electronic component, a manufacturing method and a manufacturing mold thereof, and an applied electronic device according to the present invention, the design of the decryption part and the door lock body that transmits and decrypts a signal by a touch screen is simplified and concise, thereby making it a conventional door lock. The manufacturing process is simplified compared to the method of manufacturing the body and the number parts in combination, and the manufacturing process is simplified, further reducing the production cost. In addition, since the writing method is not a pressing method, there is less fear of being intercepted by an outsider, and the exterior of the door lock can be freely formed by a design that is out of the existing door lock frame.

In addition, it is possible to freely select your own password, that is, numbers, letters and the like, in the existing cipher system using only numbers.

In Figure 1 is to buy an integrated circuit tempered glass. For clean appearance, the coating layer 1 is left without fingerprints. A transparent film 3 was placed on the tempered glass 3 and a display window 4 was placed to increase safety. At the lower end, a printed layer 5 was placed.
3 is a cross-sectional view showing the LED display window. The touch panel 8 is supported by the connecting shaft 10 and the metal bracket 9. The touch pad device includes a touch function unit for acquiring an input by a user's touch, a light emitting function unit for emitting predetermined light, and a controller for controlling light emission in response to a user input. In more detail, the touch function unit is a flat panel panel in which a user can touch a finger, and a touch pad in which numbers including 0 to 9, various symbols, alphabets, Korean alphabets, and the like are displayed. The touch pad may be disposed on a surface opposite to a surface where a finger contacts, and may include a capacitive sensor capable of detecting the approach of a finger, and a signal processor for outputting the detected finger as an electrical signal.
The sign displayed on the touch pad may be formed to have a color different from the background color of the touch pad, or may be formed to have a form of a sign (or vice versa) of a light-transmissive material on a light shielding background. The capacitive sensor is formed of at least one electrode, and when the user's finger approaches or contacts the electrode, the capacitance changes between the user's 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 is disposed on the back side of the touch pad corresponding to each marked position. 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.
The signal processor detects an amount of change in capacitance in the capacitive sensor and outputs an input signal which is an electrical signal. That is, the signal processor supplies a constant voltage to the capacitive sensor, senses the magnitude change of the voltage according to the change in capacitance, detects the approach or touch of a finger, and a sign displayed on the contact point where the capacitive sensor is disposed. Outputs an input signal consisting of a series of bits representing
Such a touch function can be applied to the configuration of a touch pad that is generally used, and the invention is not particularly limited in technology.
Next, the light emitting function unit includes a light emitting device that emits light of a predetermined color in response to an input of a power source, and a light emitting driver that supplies driving power to the light emitting device. As the light emitting device, semiconductor devices such as LEDs and OLEDs, which consume little power and have good luminous efficiency, may be used. The light emitting device may be a light emitting device that emits only a single color, or may be a multicolor light emitting device that emits light of various colors or brightnesses depending on the driving power input. In addition, by combining two or more monochromatic light emitting devices it may be to realize a variety of colors and brightness. The light emission driving unit controls the power supplied to the light emitting element according to the light emission control signal input from the control unit, and performs flashing driving to turn on and off the light emitting element indicated by the control unit. In addition, the light emission brightness and color of the light emitting device are also controlled freely. On the other hand, the touch function unit and the light emitting function unit are controlled by the control unit. That is, the control unit receives an input signal output from the touch function unit and recognizes a sign indicated by the input signal. The recognized code is output to the rear end and used for other operations, or a user for various functions built in the control unit. In addition, when the control unit recognizes the code input by the input signal, the control unit controls to blink the light emitting element disposed at a position (contact point) on the touch pad on which the recognized code is displayed. Generates a light emission control signal including information for causing the light emitting element to flash for the code and outputs the signal to the light emitting driver, the light emitting driver controlling the supply of driving power to the light emitting element. According to the present invention, a sign that a user inputs by touching a finger is correctly recognized by the controller and at the same time Since the light emitted by the light emitting device is emitted, the user can check the success of the input even with his eyes.
The dead bolt is moved forward or backward by the operation of an actuator connected to a motor, a solenoid, a manual dial or a manual lever, thereby locking or opening the door to the door frame. The dead bolt driving unit drives the actuator in accordance with the door lock control signal output from the controller to move the dead bolt forward or backward. In addition, the dead bolt driving unit may include a function of checking the operating state of the devices constituting the dead bolt driving unit under the control of the controller, and outputting a check signal indicating whether the dead bolt driving unit is a normal state or an abnormal state. The control unit may be configured to provide a door lock control signal for advancing or retracting the dead bolt in response to input from the touch function unit or input from a separate input means (such as a lock / open button disposed in an indoor unit of the door lock system). Will output On the other hand, the control unit includes a function for checking the operating state of each part of the touch pad device or the door lock system. At this time, if each part includes a function for checking its own operation state, the control unit may perform the inspection only by outputting a signal for requesting the result after the inspection. If each part can not carry out the inspection by itself, the controller can directly check the operation state. At this time, sensors for inspection should be arranged in each part. On the other hand, when the inspection of each part is completed, the control unit displays the inspection result for the user to confirm. Display is performed by making the meaning of at least one inspection result correspond to each code | symbol of a touchpad, and making the light emitting element of that code flash. Such display can also be performed by flashing a single sign, and can be variously displayed by simultaneous flashing or movement of flashing elements in a horizontal column or a vertical column. The memory unit mainly stores a password for releasing the security of the door lock system. On the other hand, in the case of registering the password in the memory unit by the user's input, the control unit receives a series of codes to register with the password, and then controls the light emitting drive unit so that the input code can be sequentially flashed. When the user who confirms the flashing codes confirms that the input is made correctly and performs an input indicating that the input is completed, the control unit stores the input codes as a new password in the memory unit, adding a new password to the door lock system. Or, if the user wants to change the existing password, the user performs an operation according to a predetermined procedure, and the control unit executes a function of registering a new password.
After that, the user enters a code to be used as a password. The control unit determines whether the input code is an input for a code to be used as a password or an input indicating completion of input for constituting a password using the codes input so far. At this time, if it is determined that the input code is input of a code to be used as a password, the input code is temporarily stored in a predetermined buffer (not shown). Then return to step to obtain subsequent input. On the other hand, if it is determined in the step that the input code is the input indicating the completion of the password input, it is controlled to flash the input codes so far in the order of input. That is, the light emission 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 control unit 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 inputs a confirmation that the password has been correctly input. It is registered and stored in the memory unit.
Although the contents of the operation check for the door lock function unit in the door lock system have been described, the present invention is not limited thereto, and all parts such as the memory unit, the touch function unit, or the light emitting function unit can be inspected.
The control unit outputs a door lock control signal for function checking to the door lock function unit to check whether the dead bolt is currently maintained in the door lock function unit or whether the dead bolt drive unit can operate normally.
Then, the door lock function unit performs self-inspection, and outputs the information indicating the inspection result to the control unit as an inspection signal. The control unit receives the check signal and checks the result of the check included in the check signal. The light emission control signal is output so that the contents of the touch pad blink one or more light emitting elements.
By this display function, the user can conveniently and easily check the light emitting elements which blink the state of the door lock. When the user obtains the individual authentication information stored in the electronic key from the electronic key recognition unit by contacting or approaching the electronic key recognition unit and outputs it to the control unit, the control unit reads the verification information stored in the memory unit, and the verification information. And authentication processing between the individual authentication information. And the control unit controls the drive of the dead bolt by controlling the door lock function 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 further includes a function of displaying the number of electronic keys currently registered or new electronic keys according to a user's request. That is, the number of registered electronic keys can be displayed by the method of flashing the corresponding number among the codes displayed on the touch pad, or by flashing any number of codes corresponding to the number of the electronic keys.
The user executes a function such as registering a new electronic key or re-registering a previously registered electronic key by a predetermined input. Then, the user contacts the electronic key to be registered with the electronic key recognition unit, and the control unit reads out individual authentication information from the contacted electronic key and stores it as verification information in the memory unit. The controller checks the number of existing verification information stored in the memory unit, and displays the number by flashing the corresponding number of the touch pad or by using the number of flashing codes. It is possible to easily identify the existence of an illegal user who registers and uses an electronic key.
When the user touches the surface of the touch pad, the touch pad has a function of recognizing a plurality of contact points at the same time or sliding contact as separate input signals, and the touch pad flashing the light emitting element at the contact point where each contact is made. Start the device. In the touch function unit, the signal processing unit includes a register (not shown) having bits corresponding to each contact point of the touch pad. 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 controller. After the output of the serial signal, the values in the registers are reset. The controller receives a serial signal output from the signal processor to determine a contact point where a user's contact occurs. The control unit then 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 the number or symbol displayed at 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 assumes that the user inputs an additional function instead of a sign input. Here, the user's contact with at least two or more contact points during the reference time slides in a multi-input operation or state in which the user makes wide contact with the finger or palm to simultaneously touch the plurality of contact points of the touchpad. This is caused by the sliding input operation of sweeping down.
That is, when the user makes an accurate contact with one contact point, the signal processor considers that the user wants to input one number, and when the user makes a wide contact or sweeping contact with the contact point, the user inputs a function other than the number input. It is to be regarded as intended. 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 stop of input, enter various function setting menus, or confirm a set function.
In the touch pad device having such a configuration, the controller performs control to blink the light emitting element disposed at the contact point whenever the user touches the touch pad.
That is, when a user's contact occurs and the signal processor outputs a serial signal, the controller determines whether the contact is a contact for inputting a general number or symbol or a contact for sliding contact or multiple touches of a touch pad to input an additional function. It detects and outputs the corresponding signal. At the same time, if it is determined that the user contact is for input of the code, the control unit controls the light emission driver to flash the light emitting element at the contact point corresponding to the code. In addition, if it is determined that the user's contact is an input of the additional function, the light emitting driver is controlled such that one or a plurality of light emitting elements designated for the additional function flash according to a predetermined rule.
It is also possible to control whether the dead bolt is currently locked or open by flashing light emitting elements of various symbols of the touch pad device or by flashing light emitting elements of a specific column or row. 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. In other words, the door lock system is locked in a locked state. At this time, the time at which 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. This can be displayed while flashing the same symbol as the number disposed on the touch pad or by a combination of a plurality of light emitting elements. 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 may be displayed by blinking. A typical door lock system provides a forced lock function to prevent the deadbolt from being unlocked by a valid password or an electronic key from the outside, and such a function is an internal forced lock switch (not shown) disposed in an indoor unit of the door lock system. Is set by
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 the present embodiment of the present invention, when such a forced lock is set, by blinking a plurality of light emitting elements of the touch pad, an external user can easily check the current state of the door lock system.
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.
