Description

DOOR OPENING AND CLOSING APPARATUS USING A PASSWORD INPUT HAVING IMAGINARY NUMBER AND THE METHOD THEREOF}

The present invention relates to a door opening and closing apparatus and method using an input of an imaginary password, and more particularly, a password having a predetermined number of digits and an imaginary number that is not related to opening and closing the door, even if the password is input together with the imaginary password. The present invention relates to a door opening and closing apparatus using an input of a password having an imaginary number to recognize a bay and perform door opening and closing in comparison with a previously stored password.

In general, the door opening and closing device is installed in the door of a large house, such as a detached house, an apartment, or an officetel to restrict outsiders. As an example of the door opening and closing device, a mechanical door opening and closing device composed of, for example, a key and a lock has been widely used to realize opening and closing of a door by matching a mechanical structure, but according to the mechanical door opening and closing device, Due to the wear and tear of the mechanical structure of the lock is performed or the intrusion of foreign matter a lot of things happen that the normal opening and closing operation is impossible.

In consideration of the disadvantages of such mechanical door opening and closing device, the outdoor device having a keypad such as a 10-key, which allows input of a password when the door is opened, and the outdoor device when the door is opened with a unique password stored in advance. There has been proposed an electronic door device, that is, a digital door lock device, which is equipped with an indoor device that performs door opening by judging the validity of a password input from the keypad of the device. According to the digital door lock device, the door is opened only when the password inputted from the keypad of the outdoor device matches the previously registered unique password in a state where the unique password is registered and stored in advance in the indoor device.

However, in a digital door lock device in which a password is input by a keypad of an outdoor device, fingerprints are left on a key corresponding to the password by the keypad or wear of the key corresponding to the password on the keypad as the number of operations increases. There was a problem that the status is remarkably prominent so that the password is easily read and the security of the password is easily exposed.

Accordingly, the digital door lock has been filed as a Korean Utility Model Application No. 2002-10418, which does not recognize the password even if the user observes the password input process.

The digital door lock is further provided with a microcomputer with a built-in password decryption program for opening the door by sequentially pressing a button of a predetermined password by a plurality of button keys formed on the outdoor handle body, the password decryption program While ignoring the signal input after the password number after sequentially inputting the set button key of the set password, it also ignores the input of a randomly input number before pressing the set password button key.

Accordingly, even if a third party watches the password input process, the door cannot be opened without knowing the correct password order and the first starting number.

However, since the digital door lock checks the password for each number every time a password is input, there is a problem that the door may be opened if the imaginary number corresponding to the password is pressed. For example, if the imaginary number entered before pressing the password is entered as '1, 2, 3, 4' while the password is '1, 2, 3, 4', the door may be opened regardless of the password.

In addition, since the validity of each password is determined, if a password error state is voiced, the actual password must be entered while all the digits corresponding to the imaginary number are completed. As the error condition is generated by voice, in this case, there was a problem that the password can be inferred by pressing another number.

Accordingly, the present invention has been made to solve the above problems, when the password associated with the actual opening and closing of the door and the imaginary number that is irrelevant to the opening and closing of the door is combined with a predetermined number of digits when the force is input for the recognition of the password only, After that, it is an object of the present invention to provide a door opening and closing apparatus and method using the input of a password having an imaginary number to determine the validity and open the door.

In addition, the present invention has another object to further maximize the security of the password can be arbitrarily changed the number of digits and the imaginary number.

In addition, the present invention has another object to prevent the door is opened only by the imaginary input by sequentially checking the validity of the password after all the password is entered together with the imaginary number.

Door opening and closing device using the input of the imaginary password of the present invention for achieving the above object, the outdoor unit is provided on the outside of the door is provided with a keypad to enter the password for the door opening and closing operation, and the inside of the door A door opening / closing device installed in a door opening / closing unit which is installed and performs door opening and closing according to a door opening and door lock signal inputted from the outdoor unit, wherein the outdoor unit is independent of door opening and closing through the keypad. And an input completion key for setting the input completion state after all the imaginary numbers applied to the imaginary number and the password combined with the imaginary number are input, and the door opening / closing unit receives the password combined with the imaginary number from the keypad. Micrograph that judges validity by unit number by recognizing password only Processor and characterized in that the password is previously stored memory and, configured digits for setting the imaginary number of digits is combined with precision, and the password in the password setting button and includes a password setting button for setting the password.

Preferably, the imaginary number is located in front of the password, characterized in that combined.

In addition, the imaginary number is characterized in that the digits selectively have a number of digits from at least one digit to the maximum infinity when the digits are not set by the digit setting button.

In addition, the door opening and closing method using the input of the imaginary password of the present invention, if a password including the imaginary number is input through the keypad installed on the outside of the door, the input password and the previously stored password in the memory is compared and justified In the method for opening and closing the door by a microprocessor for determining the number of imaginary numbers and digits of the password is set, each unit number of the set password is specified, and the key for opening the door in the password specified state When the imaginary number and the designated password are sequentially input through the pad, the imaginary number input based on the number of digits by the microprocessor is ignored and only the password is recognized, and the first digit of the password after the password is recognized. Each of the pre-stored passwords sequentially According to the procedure above, which are respectively compared with the number and the password comparison process characterized by comprising a process in which a check whether the validity of the password.

Preferably, the microprocessor is characterized in that it is determined that the password input error if the password is incorrectly input.

According to the above configuration, since the imaginary number is input together with the predetermined number of passwords, it can be seen that the password is not exposed even if the third party watches the password input process.

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

1 is a perspective view showing a door opening and closing device using an input of a password having an imaginary number according to a preferred embodiment of the present invention, Figure 2 is a front view of the door opening and closing device of the present invention, Figure 3 is a rear view of the door opening and closing device of the present invention 4 is a block diagram of FIG. 2.

As shown in this, the door opening and closing device 100 is installed on the outside of the door and the outdoor unit 110, the keypad 112 is provided to enter a password for the door opening and closing operation, and the inside of the door is installed The door opening and closing unit 120 performs door opening and closing according to the door opening and door locking signals from the unit 110.

The outdoor unit 110, the keypad 112 is provided with a plurality of buttons to enable the registration of the password and input of the password for opening the door, and the cover 113 which is slidably movable so as to be blocked from the outside; The card reader 114 is configured to read information from the card medium in which the password is stored, and includes an outer handle 116 protruding to open and close the door.

The keypad 112 is further provided with an input completion key (112a) for manipulating whether or not to complete after entering all the password.

In addition, the inside of the door is provided with an inner handle 150 for opening and closing the door from the interior side, and a battery housing 115 for supplying power for opening and closing the door.

The door opening / closing unit 120 provided inside the door determines whether the information input from the keypad 112 or the card reader 114 matches a previously stored password and the speaker SP according to the determination result. A microprocessor 122 for generating a door open signal or a warning sound, and a digit setting button 124 for setting an imaginary digit having an arbitrary digit higher than the password set by the digit and the digit for the password; , A password setting button 126 for registering the password, a door opening / closing switch 128 for manually controlling opening and closing of the door, and a memory 130 for storing the password.

In addition, the door opening / closing drive unit 132 receives the door opening / closing drive signal from the microprocessor 122 and performs the door opening / closing drive, and the door opening or door locking signal output from the door opening / closing drive unit 132. Door opening and closing mechanism 140 to perform the opening and closing is mechanically configured.

When the password input error occurs more than a predetermined number of times, it is determined that there is sufficient possibility of unauthorized intrusion, and the like through the wired and wireless communication network to notify the security company, the police department, or the mobile communication terminal of the resident by the mobile communication terminal. The processor 122 is connected to the security company terminal 160 or the mobile communication terminal 170 is configured.

The operation of the present invention configured as described above will be described with reference to the accompanying drawings.

In the opening and closing process of a general door opening device, that is, a digital door lock device (hereinafter, referred to as a digital door lock device), when the user inputs a preset password in the keypad 112, the microprocessor 122 is stored in the memory 130. It determines the validity through the comparison process with the password, and opens and closes the door by driving the door opening and closing driving unit 132 and the door opening and closing mechanism 140.

However, since the password set at the time of initial installation cannot be changed, the password may be easily exposed when it is used for a long time, and as mentioned in the related art, the number of imaginary numbers and passwords may be changed even if the password is provided before and after the password. We couldn't change it, so we couldn't vary the password combination.

Therefore, the present invention improves the security of the password by setting the number of digits of the password and the imaginary number arbitrarily as well as the user, and the password is accidentally matched by judging whether the password is valid after all the passwords are entered together with the imaginary number. It prevents the door from opening.

This will be described in detail.

Here, the imaginary number according to the present invention can be applied up to infinity and the password can be specified up to 20 digits (see FIG. 5A), but in the application example of the present invention, the total number of digits including the imaginary number is 10 (see FIG. 5B). It will be described as limited to.

6 is a flowchart illustrating an example of setting imaginary numbers and digits of a password according to the present invention. If it is described with reference to this, if you want to specify the digits of imaginary digits and the number of digits of six passwords out of the ten digits of the total digits, the digits for the imaginary number and the password is set by the digits setting button 124 (step 200), when the digits setting button 124 is operated, a voice message for sequentially setting the digits and the number of imaginary numbers and passwords is outputted, and when an arbitrary key provided in the keypad 112 is operated according to the output, The setting is completed by the control operation of the processor 122 (step 202, step 204).

Subsequently, the password setting button 126 is operated to press the keypad 112 for each unit number for a predetermined six digits to specify a password (step 206).

As such, if the number of imaginary numbers and passwords is specified, and each unit number of passwords is specified and combined, the password combined with imaginary numbers is set as shown in FIG. 5B, and the set password is stored in the memory 130 (step 208). ). At this time, the microprocessor 122 recognizes each unit number and the number of digits of the password stored in the memory 130, and if the number of imaginary digits is set, also recognizes the imaginary digits.

Subsequently, the user opens the cover 113 to open the door and manipulates a plurality of keys of the keypad 112 to input a password, the password being input including the imaginary number by the microprocessor 122. Only the password is recognized to perform the door opening operation described below.

Referring to FIG. 7, which is a flowchart illustrating a door opening and closing method using an input of a password having an imaginary number according to the present invention, one of the above-described digit setting examples, the number of the imaginary number and the password respectively is 4 digits and 6 digits. When the user enters all the passwords '4,5,3,2,4,9' including the imaginary number and presses the input completion key 112a (step 210), the microprocessor 122 determines that the imaginary number It is recognized that all the combined passwords have been entered (YES in step 212) (step 214).

When the input of the password is completed, the microprocessor 122 already recognizes the total number of digits including the digits or the imaginary number of the password. Therefore, the microprocessor 122 ignores the imaginary number previously input based on the number of digits and determines whether the password is valid. (Step 216).

Here, if the input completion key 112a indicating that all the passwords have been input is not input or there is no password input for a predetermined time, a separate process of providing the user with a password error state through a voice message or an alarm is performed. (No in step 212). Of course, if a password is input within a predetermined time and the input completion key 112a is manipulated, the process proceeds to step 214.

When the input of the password is completed as described above, the microprocessor 122 determines whether the digits of each of the six digits of the password is justified. If it matches the first stored unit number, the next two digit password '5' is judged as legitimacy, and the process of determining the validity is performed sequentially to check whether the password matches the password stored in the memory for all six digits ( Step 218) (step 220).

If each password is not correct, the password error situation is immediately provided to the user (NO in step 218). That is, if the user presses "(imaginary) + 4,5,3,2,5,9", the number 5 in the fifth digit in the validity judgment process is '4' which is password data stored in the memory 130. Since the password is incorrectly input to the user through the speaker (SP).

This is by checking the password for each number each time the password in the prior art, if you press the imaginary number matching the password, the door can be opened, but once the password including the imaginary is entered once all Since the validity of the password is determined in step S, it is not immediately opened even if the imaginary number arbitrarily matched with the password, but the door is opened by checking the input password (step 222).

For example, assuming that the password is set as '1,2,3,4', the password '1,2,3' after the random number '2,3,4,5,6' is pressed. When '4' is pressed in sequence or password '1,2,3,4' is pressed first and '2,3,4,5,6' is pressed, the door is recognized as a continuous password input and the door is opened. , If a third party accidentally presses any number before or after the password '1.2.3.4' and then presses the same numeric unit as the password, that is, the number is '1,2,3,4,5, ...'. ', In order to determine the legitimacy first by numerical unit first, the door can be opened before the actual password is pressed.

On the contrary, according to the present invention, since the microprocessor 122 recognizes that a password has not yet been input even if an arbitrary number of imaginary numbers is pressed, the door is not opened and the input of the password having a predetermined number of digits is completed. The imaginary number entered is ignored and only the password is recognized to determine the validity.

On the other hand, if the wrong password is entered a predetermined number of times, for example, three or more times when the password associated with the imaginary number is input to the security company terminal 160, or password to the mobile communication terminal 170 owned by the resident through the communication network Notify the user that the input error status is more than three times and there is a possibility of unauthorized intrusion, and provide the security system by providing the security company by dispatching the security company directly or by allowing the residents to contact the police department.

In addition, since the user can arbitrarily change the digits of the imaginary number and the password by manipulating the digit setting button 124, it is possible to prevent the exposure of the password to the maximum.

Here, although the digits for the imaginary number are set as in the above-described embodiment, if the digits for the imaginary number are set only if the digits for the imaginary number are not set by operating the digit setting button 124, before the user presses the password. It is possible to press the imaginary number from at least one digit to the maximum infinity, and after pressing the imaginary number, by pressing the set password and manipulating the input completion key 112a, the microprocessor 122 stores the password and the input password stored in the memory. By comparison, the validity is judged.

As described above, according to the door opening and closing apparatus and method using the input of the imaginary password of the present invention, since the validity of the password is determined after all the passwords including the imaginary number having a certain number of digits, the conventional imaginary number When opening the door by a password that contains a password, the door is not opened even if a third party enters an imaginary number identical to the password by mistake, as each password number is inputted, and it is determined whether it is justified or not. .

In addition, the present invention can change the imaginary number and the number of digits, that is, the number of the password to the user arbitrarily, there is an effect that can provide a variety of password combinations.

On the other hand, although the embodiment of the present invention has been limited to the digital door lock device, it can be variously applied to various security alarm devices, password systems inputted by keypad means such as safes, PCs, and ATM machines of banks.

Therefore, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims.
