As described in the above problem solving means, the digital door lock and control method according to the present invention generates a random number after inputting a password, by allowing the user to input the random number generated by the user to input a number other than the password evenly This prevents fingerprints from being exposed, resulting in greater security.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a conventional digital door lock, Figure 2 is a system block diagram of a digital door lock according to a preferred embodiment of the present invention, Figure 3 is a detailed block diagram of the controller of FIG.

Since the present invention is characterized by an interface for password and random number input, the appearance may be similar to that of a conventional digital door lock as shown in FIG.

2 and 3, the digital door lock according to the present invention stores the key input unit 110 and the set password to receive the password and random number, generates a random number, the password and random number input from the key input unit It may be configured to include a control unit 120 for controlling the opening and closing of the digital door lock by determining whether or not coincidence and the opening and closing unit 130 is controlled to open and close according to the control unit.

The key input unit 110 may be any configuration capable of key input, and may be configured by a conventional keypad or a touch screen method.

Here, the key input unit 110 is located at the bottom LED, It should be a configuration in which illumination can be applied using an EL element, a backlight, or the like, and a configuration in which illumination can be individually applied to each number.

The controller 120 may be implemented by a microprocessor, an embedded system, or the like, and controls the memory 121 storing the set password and the predetermined random number table and the entire system, and the password and the random number input through the key input unit. And a brightness control module 123 for controlling the lighting of the keypad to guide the input of the random number extracted from the random number table and the CPU 122 for controlling the opening and closing of the digital door lock by determining whether the coincidence is identical. Can be.

The memory 121 may store and manage a password set by a user and store and manage a random number table that provides a random value generated after inputting a password.

Here, the random number table refers to a table which is formed in a combination that can be changed every time a password is input and stores random numbers whose numbers do not overlap each time. The random number table may be configured to store a random number set in advance by a random number generation function or any combination, and then extract one random number every input.

In addition, the controller may further include a random number generation module 124 for generating a random number in real time when inputting a password, as shown in FIG.

When the random number table is stored in advance, it is preferable to include a random number generation module 124 capable of generating a random number in real time according to the password because the random number may overlap with the password when the password is changed.

The random number generating module 124 may be configured by software or hardware, and may generate random numbers in any combination using a random number generating function, and generate random numbers so that random numbers generated every input according to a preset rule do not overlap. Can be. In addition, the random number input immediately before may be stored and control may be performed such that a random number that is not duplicated is generated. The random number generation module 124 as described above may be formed as a simple program implementing a random number generation function, and may be implemented as a program by a conventional random number generation function.

The random number generated is a configuration for preventing the password from being exposed because the fingerprint remains only in the numbered part of the password when the password is input, so any combination of the fingerprint can be buryed by pressing the non-password evenly every time the password is input. It is possible.

In addition, the brightness control module 123 controls lighting to induce a user to input the generated random number.

More specifically, the brightness control module 123 applies illumination to the first random number generated under the control of the CPU 122, and if the corresponding number is input, applies the illumination to the next random number to input the last random number. It is responsible for controlling the lighting applied repeatedly.

In addition, the brightness control module 123 applies illumination to the remaining numbers except the first random number generated under the control of the CPU 122, and if the corresponding number is input, applies the illumination to the remaining numbers except the next random number. Lighting can be applied in such a way.

Figure 4a is an exemplary view showing that the illumination is applied to the key input unit using the LED device according to a preferred embodiment of the present invention.

Referring to FIG. 4, the LEDs 111 may be separately formed for each number under the key input unit, and each LED may be electrically connected to only the LED of the corresponding random number transmitted from the CPU according to the switching control of the brightness control module. The lighting may be controlled to be applied under the key input unit.

If the lighting is applied to the remaining numbers other than the random number, only the LEDs 111 of the remaining numbers except the random number may be electrically connected according to the switching control of the brightness control module so that the lighting is applied.

4B is an exemplary view illustrating that illumination is applied to a key input unit using a touch screen method according to an exemplary embodiment of the present invention.

Referring to FIG. 4B, the key input unit may be configured as a touch screen method for sensing capacitance, and in this case, the brightness control module 123 controls the driver circuit (gate driving circuit and data driving circuit) to switch the device (not shown). By controlling the transmission of the liquid crystal with respect to the light incident from the backlight unit (not shown) according to the driving of the h) may be controlled to display the light only in the panel portion corresponding to the random number and to display in dark the portion corresponding to the remaining number. On the contrary, only the panel part corresponding to the random number may be displayed dark, and the part corresponding to the remaining number may be displayed brightly.

In addition, any configuration can be applied to the keys of the random number through the light or dark, light or off, color (blue, green, red, etc.) can be distinguished from the keys of the remaining numbers.

Since the brightness control of the touch screen method is obvious to those skilled in the display field, a detailed description thereof will be omitted.

A detailed lighting application method will be described in detail in the digital door lock control method to be described later.

Then, the opening and closing unit 130 performs a role of opening the digital door when the CPU 122 of the control unit checks whether the input password and the random number match and transmits an open signal. More specifically, the configuration of the opening and closing unit 130 is not only obvious to those skilled in the art, but also omitted from the core of the present invention.

Hereinafter, a digital door lock control method according to the present invention will be described.

5 is a flowchart schematically illustrating a digital door lock control method according to an exemplary embodiment of the present invention.

Referring to FIG. 5, a password is input from a user through a key input unit 110 (S110).

If a password is entered, check if it matches the saved password. More specifically, when a password is input, the CPU 122 of the controller checks whether the password matches the password stored in the memory 121 and controls the next step.

Subsequently, the random number value stored in the random number table of the memory 121 is extracted or the random number generation module generates a random number in real time and provides the user with the input. (S120)

Here, the number of digits of the generated random number may be variously determined by setting.

FIG. 6 is a detailed flowchart illustrating step S120 according to the present invention, and FIG. 7 is an exemplary diagram illustrating input of a password and a random number.

6 and 7, when a password is input, only the portion where the password is input remains in the fingerprint. If the password is 12345, the fingerprint remains only on the 12345 number (FIG. 7A). In this state, random numbers are generated and input.

When a random number is generated, the lighting is controlled to induce a random number input, and the CPU 122 extracts the first random number and transmits it to the brightness control module 123, and the brightness control module 123 lights only the random number. It is controlled to be applied. If the first random number is 8, only 8 is illuminated (Fig. 7b).

As above, when illumination is applied to the first random number, the user inputs the corresponding random number. When the first random number is input, the CPU 122 recognizes this, extracts the second random number, and transmits the second random number to the brightness control module 123. The brightness control module 123 controls the illumination to be applied only to the corresponding random number. If the second random number is 7, only 7 is illuminated (Fig. 7c).

 As above, when illumination is applied to the second random number, the user inputs the corresponding random number. When the first random number is input, the CPU 122 recognizes this, extracts the third random number, and transmits the third random number to the brightness control module 123. The brightness control module 123 controls the lighting to be applied only to the corresponding random number. If the third random number is zero, only the zero is illuminated.

If the number of the random number is three digits, 870 becomes a random number generation code as in the above embodiment, and when the password 12345 and the random number generation code 870 are input and match, the CPU 122 controls the opening and closing unit 130 to be opened. In the above embodiment, the illumination is applied only to the random number, but on the contrary, the illumination may be controlled to be input only to the non-random number.

Here, the random number generation module 124 may store the random number 870 generated the next time the password is input and then control to generate a random number among the numbers other than 870 so that all numbers are evenly pressed.

Through this, all numbers are used when used more than once, so password tracking becomes impossible as a fingerprint.

The algorithm according to FIG. 6 is configured to be terminated immediately if the CPU does not match by determining whether the input number matches each time an individual number (8,7,0) corresponding to the random number is input. In order to apply fingerprints evenly to the non-numbered numbers, after all the individual numbers (8,7,0) corresponding to the random number have been entered, the CPU will determine whether the entered numbers match and, if they match, open and close the door. If the configuration can be implemented to terminate.

Although the detailed description of the present invention described above has been described with reference to the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, and those skilled in the art will appreciate It will be understood that various modifications and changes can be made in the present invention without departing from the spirit and scope of the invention.
