Description

DOOR OPENING AND SHUTTING APPARATUS USING A TAKING NOTES TYPE PASSWORD ENCRYPTION SYSTEM}

The present invention relates to a door opening and closing device using a handwriting encryption system, and more particularly, to provide a touch sensor (Touch Sensor) for detecting a finger movement on a handwriting key unit installed on the outside of the door, the touch It relates to a door opening and closing device using a handwritten encryption system that allows the door to be opened and closed according to the validity of the password set in accordance with the Hangul handwriting order by the sensor.

Generally, a door opening and closing device is installed in a door of a large house such as a single house or an apartment or an officetel in order to restrict the access of outsiders. An example of the door opening and closing device is opening and closing of a door by mechanical matching. For example, a mechanical door closing device composed of a key and a lock is widely used.

Recently, an outdoor device having a 10-key capable of inputting a password when the door is opened and a unique password are stored in advance so that the door is opened by judging the validity of the password input from the 10-key of the outdoor device when the door is opened. There is proposed an electronic door device having an indoor device configured to perform a bar code. According to such an electronic door device, a password input from a 10-key of an outdoor device is pre-registered with a unique password registered and stored in advance in the indoor device. The door is designed to be opened only if it matches a unique password.

However, according to the mechanical door opening and closing device, there is a problem in that the mechanical structure of the lock, which is opened and closed by a key, wears out over time, or the normal opening and closing operation is impossible due to intrusion of foreign matter.

In addition, even in the electronic door opening and closing device of the password input method using the 10-key, the fingerprint corresponding to the password of the 10-key is left or the fingerprint corresponding to the password of the 10-key is increased according to the increase in the number of operations. The wear condition becomes remarkable, so that the password is easily read, which makes it difficult to maintain the security of the password, and also requires the circuit configuration for the 10-key used for the input of the password, which complicates the overall electronic door opening and closing device configuration. There was a problem.

Therefore, the present applicant has proposed a method of setting a password by inputting Korean or Arabic numerals with a plurality of buttons, and has developed and applied a Korean encryption system for opening and closing a door according to an encryption code system (Domestic Patent Application No .; 1993-31768) In addition, there is an advantage that encryption can be realized by ordering and arranging letters by applying Hangul, which can be an infinite cipher system, and registering Hangul password or inputting Hangul password for door opening and closing. In this case, there were inconveniences in operating a button by inputting Korean or numbers by operating a plurality of pre-installed buttons (preferably provided with four provided).

That is, by operating the four buttons that can input the Hangul and numbers as described above, you can set a variety of password patterns according to the input sequence of the Hangul and numbers, but when entering the password set to the Hangul letters or numbers for door opening and closing The user has to operate each of the four buttons according to the input order and input method. In this case, if the button operation is difficult due to mechanical defects, the door cannot be opened or closed.

In addition, there are cases in which the iris recognition system or the fingerprint recognition system is applied to limit the access of outsiders in addition to the door opening and closing device as described above, but since the price is expensive, the installation place is extremely limited, and when an error occurs, There is a problem in that the economic cost increases because it requires a professional manpower to repair.

Accordingly, the present invention has been made to solve the above problems, and provides a plurality (5) of the touch sensor that can detect the finger movement on the handwritten key unit installed on the outside of the door for opening and closing the door.

1 and 3, the door opening and closing apparatus using the handwriting encryption system according to the present invention, the handwriting key unit is installed on the outside of the door to perform the password registration and password input for the door opening and closing operation ( 100) is installed inside the door and is connected via the handwriting key unit 100 and the connection connector 110 and performs door opening and closing according to the password registration and password input signal of the handwriting key unit 100. The door opening and closing unit 200 is composed of.

The handwriting key unit 100 has five touch sensors 104 for registering a password and inputting a registered password according to the operation of the password mode setting switch 204 of the door opening / closing unit 200 which will be described later. A display element 106 provided on the display 102 and configured as an LED for displaying the operation state during a predetermined driving for opening and closing the door, and a door open confirmation button for inputting a password and confirming whether the door is opened or closed when the door is opened and closed. 107a and the door closing confirmation button 107b are included.

In addition, the handwriting key unit 100 has a sensor-sensing unit 108a for recognizing the handwriting input handwriting input when a user touches five upper surfaces of the touch sensors 104 and writes a predetermined Hangul and numerals, respectively. A double-sided PCB substrate 108 provided with a data transmission unit 108b is provided to transmit the encryption data according to the recognition result of the sensor sensitive unit 108a to the door opening and closing unit 200.

In addition, a special writing board (not shown) made of glass and metal is easy to write on the touch sensor 104.

And, as shown in Figure 4, the pad 102 is configured to be coupled to / separated from the external decoration, it is possible to select and combine the various types of external decoration (102a).

In addition, the touch sensor is configured up to 1-5 times as shown in Figure 5 and will recognize the predetermined Hangul according to the handwriting sequence (arrow direction) described later.

On the other hand, the door opening and closing unit 200 is a door lock button 202a / door opening button 202b which is installed for door opening and door lock in the door interior side, and the predetermined conditions when registering the password setting by a predetermined number of Korean characters A password mode setting switch 204 provided to perform password registration, a memory unit 208 for storing one or more setting registered passwords according to the password mode setting switch 204 operation, and the handwritten key unit ( A control unit 205 for controlling the overall door opening and closing operation by comparing the input data and the encryption data and setting the encryption data inputted from 100, and the door opening and closing operation member according to the door opening and closing driving signal of the control unit 205. To manually operate the door opening and closing drive unit 210 and the door opening and closing operation unit 210 are provided with a reduction motor 210a and a link member 210b coupled to one end thereof to drive the 212. When a manual registration switch 214, a power supply unit 203 for supplying predetermined power required for the door opening and closing, and a password registration / input / door opening / closing operation or the like are generated according to the control operation of the control unit 205, A beep output unit 206 is provided to provide an audible state.

Here, reference numeral 201 denotes a connection terminal unit for connecting the connection connector 110. And, 220 is a clasp for the door opening and closing operation member 212 is inserted / removed to open and close the door.

On the other hand, Figure 2 is an exploded perspective view showing the door opening and closing unit of Figure 1, as shown therein is a deceleration motor that receives a predetermined control signal from the control unit 205 according to the validity of the password, and operates as a door opening and closing drive ( 210a and a link member 210b coupled to the boss protruding from one side of the reduction motor 210a and rotating according to the operation of the reduction motor 210a and the opening and closing operation of the door according to the rotation movement of the link member 210b. Door opening and closing operation member 212 to perform the combination is configured.

The operation of the door opening and closing device using the handwritten encryption system configured as described above will be described.

Here, the password setting process performed according to the present invention will be described only for Hangul consonants and vowels, but can also be set password in a predefined state, such as numbers or special characters.

First, as shown in FIG. 6, the user may set and register a password including a predetermined word and a sentence by applying a consonant and a vowel in Korean according to the password mode setting switch operation (step 300). Among the mode setting switches 204, the input cipher setting can be changed according to the selection operation of reference numerals 204a and 204b. In other words, when the password mode setting switch 204a is operated and selected, password input such as a normal sentence is performed. On the other hand, when the password mode setting switch 204b is operated and selected, a password input such as one syllable or a short word is performed instead of the above sentence. However, an encryption pattern input by the operation of the encryption mode setting switch 204a or 204b is not predetermined, and may be set differently according to the user's convenience, or the encryption pattern may be ignored while the encryption pattern is ignored.

Subsequently, when the password mode setting switch 204 operation is performed, it is possible to perform password registration with a predetermined alarm sound (for example, beep) (step 302) (step 304).

The cryptographic registration is first performed on the handwritten key unit 100 to input Korean consonants and vowels along the five touch sensors 104 that can sense finger movements. The input procedure will be described in detail. Let's do it.

First, as shown in FIG. 5A, when writing 'AB' in Korean consonants, 1, 2, and 4 times of five touch sensors 104 are performed with a predetermined finger (preferably, an index finger) according to a general handwriting order. When the touch sensor point is written in the direction of the arrow, the 'a' data is transmitted to the control unit 205 through the data transmission unit 108b according to the sensor response operation.

At this time, after writing the letter 'a', a predetermined alarm sound (eg, beep) is provided to the user through the beep output unit 206 to notify that the password input is normally processed. In this case, by pressing the cipher mode setting switch 204, a predetermined alarm sound (for example, ding dong deng) is output and the cipher input process is terminated.

However, if the user wants to input another Korean consonant or Korean vowel after inputting 'a', the user may continue to input a predetermined consonant or vowel afterwards without manipulation of the encryption mode setting switch 204. For example, FIG. When the 'b' consonants are input in the comparable order of the 1, 3, and 4 times, the 'b' consonants are also transmitted to the control unit 205 through the data transmission unit 108b according to the sensor-sensitive operation.

Subsequently, when the 'c' consonants are written along the touch sensor in the handwriting order of 1, 2, 3, 4 times, the same Hangul consonants are transmitted to the control unit 205 according to the handwriting order, and the encryption mode is completed in order to terminate the password input. When the setting switch 204 is operated, each of the consonants of the 'b', 'b', and 'c' inputted with the password registration mode is canceled and stored in the memory unit 208 as the set password according to the control operation. (Steps 306-step 316).

When the set password is stored, a predetermined recognition sound (eg, ding dong deng) is output that the password registration mode has been released (step 318).

In addition, even when the Korean vowels 'TT', 'ㅡ', 'ㅣ', etc. are used, as shown in FIGS. When writing to, the written vowel data is recognized according to the sensor-sensitive operation, and stored in the memory unit 208 according to the control operation of the controller 205.

Meanwhile, as described above, in addition to inputting vowels of 'ㄱ', 'ㄴ', 'ㄷ' and vowels of 'TT', 'ㅡ' and 'ㅣ' independently, the consonants and vowels are combined to combine Korean words / It is a matter of course that a sentence can be registered by constructing an encryption pattern.

For example, if the user wants to store 'Hong Gil-dong' as a registration password, the combination of inputting Korean consonants and vowels is performed. First, the controller operates the encryption mode setting switch 204 to notify the controller 205 of the start of password registration. You can write 'ㅎ, ㅇ, ㅇ', 'ㄱ, ㅣ, ㄹ', 'ㄷ, ㅗ, ㅇ' in order. Of course, when writing each of the Korean consonants and vowels, the handwriting must be written along five touch sensors so that the consonants or vowels can be represented according to a predefined writing pattern. In addition, because it can be written in a curve, it is possible to enter a number of characters (Hangul, numbers, English letters, special characters, etc.) according to various personal patterns as a password.

When inputting Korean consonants and five sounds of 'ㅎ, ㅗ, ㅇ', 'ㄱ, ㅣ, ㄹ', 'ㄷ, ㅗ, ㅇ' as above, the input operation is performed each time the input operation of each syllable is completed. A predetermined alarm sound (beep) that has been performed normally will be alarmed through the signal sound output unit 206.

In addition to inputting all Korean consonants and vowels representing 'Hong Gil-dong' as described above, the word may be represented by inputting only consonants of 'ㅎ', 'ㄱ' and 'c'.

If the user wants to confirm whether the door is opened and closed correctly by inputting the password registered by the user in the state of registering the password setting as described above, if the door is opened and closed by pressing the door open confirmation button 107a, the correct password is entered. If the password is not entered or the door is not opened, the password is not valid and the user must re-enter the password. In addition, by using the door closing confirmation button 107b, it is possible to determine the password justification by determining the state in which the door is closed according to the password input.

A plurality of password patterns input according to the above-described procedure can be set and registered, and accordingly, each member of the family can individually open and close the door as a password registered by themselves. That is, there is only one door opening and closing device, but at least one password may be opened or closed.

As described above, a process of performing the opening / closing operation of the door in the normal door opening / closing mode state when the password setting registration is completed will be described with reference to FIG. 7.

First, in the case of the door lock state by determining whether the door state is the door lock state (step 400) (step 402), the five touch sensors 104 provided on the handwritten key unit 100 with the password registered by the user are set. Handwriting is performed using the finger (step 404).

The process of inputting predetermined data on the handwritten key unit 100 is the same as the encryption setting registration method described with reference to FIG. 5 and will be omitted below to avoid redundant description.

That is, assuming that the password registered by the user is 'B', 'B', 'B', the user writes via the touch sensor numbers indicating 'B', 'B', 'B'. At this time, the 'b', 'b', 'c' may be continuously input, but when entering the 'b', 'b', 'c' when registering the password setting, after pressing each consonant a predetermined time ( For example, if the next consonant is pressed after the elapsed time, each consonant should be pressed and the next consonant should be pressed after the alarm sound (beep) is output even when the 'b', 'b', 'c' consonants are input.

Therefore, it is a matter of course that the consonant data should be input in the handwriting order in which the consonants were written. For example, when the 'A' consonants are written in the order of the touch sensors 1, 2, and 4 when registering the password setting, the handwriting must be performed through the 1, 2, 4 touch sensors in the same manner as above. .

Accordingly, the control unit 205 compares the input data with the encryption data previously registered in the memory unit 208 (step 406). If the input data and the encryption data are the same, a predetermined alarm sound (for example, The deceleration motor 210a is driven in accordance with the control operation of the control unit 205 together with the ding dong output, and the door opening and closing operation member 212 according to the rotational movement of the link member 210b coupled to one side of the deceleration motor 210a. Is slid in one direction while seated on clasp 212 to perform the door opening operation (steps 408-412).

However, if the password data that has already been set and the data input by the user do not match (NO in step 406), the user can input again a predetermined number of times (step 414). 205, the door opening operation is not performed. For example, in addition to inputting data different from the cipher data, the control unit 205 does not perform the door opening operation even when the writing order is different when a word is written by combining Korean consonants and vowels when registering the first cipher data. .

That is, as described above, not only the consonant handwriting order but also the handwriting pattern and the handwriting order which are initially set and registered at the time of word input should be the same.

If you refer to the syllable syllable of the word 'forsythia', the 'dog' was written in the order of handwriting such as touch sensors '1 · 2 · 3' and '1 · 3 · 5 · 2 · 4' when registering the password. Assuming that the same syllable 'dog' data is input in the following order, such as '3 · 2 · 1' and '1 · 3 · 5 · 2 · 4', the control unit 205 registers previously. If it is determined that the handwriting order of the encrypted data and the input data is different, and if it is determined that the handwriting order is different from each other, for example, the handwriting order such as '3 · 2 · 1' and '1 · 3 · 2 · 4 · 5' If the word is written, the control unit 205 determines that the input encryption data is incorrect and does not perform the door opening operation.

Therefore, in order to perform the door opening operation, the user may write the Hangul along the corresponding touch sensor 104, such as '1 · 2 · 3' and '1 · 3 · 5 · 2 · 4', which are the writing order at the time of registering the password. When the door is opened according to the password matching. In this case, after inputting the Korean consonants or vowels one by one, a predetermined signal sound indicating the operation state is output and an alarm sound such as 'ding dong deng' is output even when the door is opened to notify the user that the door is opened.

On the other hand, in the case of locking the door that is opened according to the password input from the outside of the door, the door lock operation is performed while outputting an alarm sound such as 'Ding dong' when one of the five touch sensors is operated. When the door is to be locked or opened from the inside, the door is opened and closed with an alarm sound output by operating the door lock / open button 202 provided on the door opening / closing unit 200.

Further, in order to prevent the door from being easily opened by only operating the door open button 202b of the door open / close unit 200 provided inside the door, the door may not be opened even by simply operating the door open button 202b.

For example, when the door lock / open buttons 202 and 202a and 202b are simultaneously pressed for two seconds or more, the function is inputted with an alarm sound. Accordingly, even when the door open button 202b is pressed, the door is not opened. In this case, pressing the door lock / open buttons 202a and 202b simultaneously for 2 seconds or more can release the function together with the alarm sound.

On the other hand, in addition to inputting a password by handwriting using the touch sensor 104, the touch sensor 104 is manipulated to recognize a handwriting order as described above when inputting a predetermined character, respectively. You can do it.

For example, if you want to write 'ㄱ' among Korean consonants, press 1, 2, and 4 touch sensor points among the five touch sensors 104 in the direction of the arrow with your finger according to the general handwriting order. The 'a' data is transmitted to the controller 205 via the data transmitter 108b. Therefore, even if the touch sensor is operated in the order of 1, 4 and 2, even though the same 'b' data is generated, the button pressing sequence is different, so that the door is not opened.

If you combine the Hangul consonants and Hunminjeongeum 28, as mentioned above, you can make 1.75 billion Korean letters, and about 39.9 billion syllables. You can have it. In addition, even when combining the consonants and vowels to form predetermined words and sentences, it is possible to generate different encryption data according to individual behavior patterns, that is, the order of letters or arrangements, so that the encryption patterns are more efficient than other door opening and closing devices. It is available.

Since the handwriting encryption system can be applied not only to Korean alphabet but also to English alphabet, the application range can be maximized, and the encryption pattern to which the English alphabet is applied can be applied in the same manner as the encryption pattern applied to the Korean alphabet.

The door opening and closing device using the handwriting encryption system may be applied to a door, a safe, a car, as well as a door, and the encryption pattern for inputting and setting encryption by inputting Korean and English in the handwriting encryption system is mobile communication. Applicable in a terminal or the like, although the present invention has been described limited to the door device, even if the modified embodiments are protruded because of its wide application range as described above, it should be understood individually from the technical idea or the prospect of the present invention. Should not fall within the scope of the claims appended hereto.

As described above, the door opening and closing apparatus using the handwriting encryption system according to the present invention comprises five lines of a touch sensor for detecting a user's finger movement, and a handwriting of a predetermined letter / number through the touch sensor. By registering the password setting by arranging in order (letter order, letter sequence, etc.), even if you know the above-mentioned registered cipher phrases, the door is opened and closed only when the order of letters, letter sequence, time, and speed is matched. You can do it.

In addition, the user does not have to carry a separate key for opening and closing the door, and without the hassle caused by the password operation, the user can simply and easily write the registered word and sentence with the password as it is written. There is.
