Description

Method of driving control for fingerprint identification door-lock system

The present invention relates to a fingerprint recognition door-lock driving control method, and more particularly, to distinguish and store the fingerprint in the normal state and the fingerprint in the alarm state when storing the fingerprint, and forcibly opening the door by another person. In this situation, when the user inputs the fingerprint stored in the alarm state, the door is opened and the notification is automatically made through the preset emergency contact network, thereby improving the reliability of the fingerprint recognition door lock device. It is about a method.

In the current information society, the leakage of information, compulsory entry and exit from outsiders, including companies and homes, are thoroughly complemented.

Among them, the door prevention system is also a technology that is remarkably developed.

It is used from the method of locking with a key to the method of opening and closing a door by recognizing a fingerprint.

The fingerprint recognition door-lock device recognizes the fingerprint in the door when the user wants to open or close the door while the fingerprint is stored in the memory. If the fingerprint is the same as the fingerprint stored in the memory, the door is opened. The device does not open.

The fingerprint door lock device currently in use is a 1: 1 door lock, which requires a user to enter a password that only the user can know to recognize the fingerprint. Save the fingerprint corresponding to.

However, in the 1: 1 door-lock method used as described above, since all the key pads including function keys such as fingerprint registration and deletion are installed outside the door, a third party knows how to operate the door-lock. If it is, it can not be ruled out that the door can be opened and closed by inputting the third party's fingerprint.

In addition, the fingerprint door-lock system currently in use is too small to store fingerprints, so in a family home where only one fingerprint can be entered per user, when a finger is damaged when a fingerprint is entered There is an inconvenience of not being able to control the door.

In addition, the biggest problem in the conventional fingerprint recognition door-lock system as described above is that when the door is forcibly opened by another, if the wrong fingerprint is entered, the door does not open, so the other person is suspicious and must open the door.

Therefore, when a door is forcibly opened by another person, a report must be received through a police station or an emergency contact network immediately, and a technology is required so that others cannot know the operation at this time.

The present invention, in consideration of the conventional requirements as described above to open the door by the other by inputting the fingerprint to distinguish between when opening the door in a normal state and when the door is opened in a coercive state by other parties. If it is, it aims to report to the police immediately.

In addition, another object of the present invention is not to permanently delete the data deleted by the door-lock device immediately, but to separately reload the data for a specific period set by the manufacturer to keep the deleted data separately in the deleted data storage file, the period It is intended to prevent cheating by users (eg, homeowners) by permanently deleting it after this time.

In addition, another object of the present invention is to allow the user to operate the door-lock by inserting the emergency battery from the outside through the emergency battery connection terminal when the user failed to replace the battery of the door-lock device due to long-term business trip, etc. If the part is damaged, it is intended to connect the emergency card through the service center and to enter the user secret code there so that the door can be opened.

An optical lens (2) for transmitting a fingerprint recognized in the fingerprint recognition window (1) to a programmable logic device (3);

A programmable logic device (3) for digitizing a fingerprint transmitted through said optical lens (2);

An external terminal connection portion 7 used as a signal transmission and a communication connection means with an external communication means for controlling the driving of the fingerprint recognition door lock device;

A central processing unit (4) for controlling the operation of each unit;

A flash memory (5) for storing control logic operated by the central processing unit (4);

A DRAM (6) for storing the data fingerprinted;

A door internal key pad 8 having a function key used when a user wants to operate a function of the door-lock system; And

A door external key pad 9 having a numeric key used when a user inputs a password together with a fingerprint input is provided.

Referring to the operation of the fingerprint recognition door lock device configured as described above are as follows.

The user first inputs a password inputted together with his / her fingerprint by using the key pad 8, and then recognizes the fingerprint of the user's finger in the fingerprint recognition window 1. The fingerprint is input to the programmable logic device 3 via the optical lens 2.

The programmable logic device 3 converts the input fingerprint into data and transmits the data to the central processing unit 4. The central processing unit 4 receives the master's approval in order to operate a door function, and the master's input password. And, if the fingerprint is matched, and if the fingerprint is matched, the function of the door can be operated, and if the user wants to open the door outside the door, the user's password and fingerprint are input, and the input password and fingerprint are stored in the memory. If the password and fingerprint match, the door driving signal is output to the external terminal connection unit 7 to control the door to be opened.

At this time, the password entered above can be selected when the user wants to open the door by fingerprint input only, or when the user wants to open the door by entering both the fingerprint and the password. There's no need for a numeric keypad installed, and the door opens just by entering your fingerprint.

Hereinafter, a process of distinguishing and storing a fingerprint in an alarm state and a fingerprint in a normal state according to the present invention will be described with reference to FIGS. 2A and 2B, and an emergency contact process will be omitted.

First, the fingerprint door-lock device always checks whether its battery voltage is higher or lower than a certain voltage (S1) and waits for a battery exchange by the user if lower than the current voltage (S2). Wait for key input by operation.

When the driving start button of the fingerprint recognition door-lock device is input, it is determined whether the input key is input from the inside of the door-lock or from the outside, and if it is input from the inside, it corresponds to the next key value to be input. If the process (S3) is input from the outside, the following process (S4) is performed according to whether the alarm state or normal state of the fingerprint is input.

When the process S2 is described in detail, when the current voltage is lower than the set voltage, the door lock device can no longer be driven. In this case, the user takes action according to the state of the door lock device.

If the current voltage checked above approaches the set voltage, the door-lock device notifies the user of the replacement of the battery for a certain period of time. The user can replace the battery at this time, and even if the alarm is not heard, the battery can be replaced internally.

If the user returns after leaving the house for a long time, open the door by connecting the battery through the emergency battery connection terminal installed outside the door lock.

At this time, the door-lock device determines whether there is a breakage in the battery part internally, and if an emergency battery is connected in a state where there is no breakage, the door-lock device then performs a normal door-lock function. That is, the door is opened and closed through fingerprint authentication (S22).

If the damage is judged to be damaged, wait for the emergency card to be connected. If the door-lock device does not operate even though the emergency battery is connected, contact the service center to access the emergency card, and then enter the pre-stored secret code. do. When the secret code is input, the door is opened, and then the damaged battery is replaced (S23).

For reference, the secret code is a code that only the master user knows. This is to prevent the situation that the door can be opened by the emergency card without the user's knowledge in the service center.

Meanwhile, when the door-lock driving start button is input in detail, the process of S3 is described in detail. If the key input next to the driving start button is determined to be the key, the current opening mode is always opened. It is determined whether the state mode is' S31.

As a result of the determination, the door is opened when the door is always in the open mode, and the door is open when the password is input because the password is open because the door is not in the open mode.

In addition, if the key input after the door lock start button is the key for registering the main master, the fingerprint of the main master is inputted, and the fingerprint corresponding to the normal state and the fingerprint corresponding to the alarm state are received and registered in the memory. (S33).

In addition, if the key input after the door-lock start button is a key for additional registration of users, the fingerprints of the users are registered under the authentication of the main master, which is also a fingerprint corresponding to a normal state and a fingerprint corresponding to an alarm state. Register each (S34).

In addition, if the key input after the door lock start button corresponds to the delete key (refer to FIG. 2B), the selected data is deleted (S35). In this case, the deleted data is not completely removed, but is additionally deleted data. Store in a delete file for storing (S36).

Then, the storage date of the deleted data is counted and completely removed after a predetermined period of time (S37).

The reason why the master does not delete the data to be deleted immediately is to store it in a separate deletion file for a certain time. The master binds with an outsider, registers the fingerprint of the outsider, and then makes the outsider do the wrong thing. If you erase the fingerprint, the police can determine that the master has been damaged to prevent this.

In addition, if the key input after the door lock start button is a key corresponding to the key set mode for setting the key value, the user inputs the key value corresponding to the input key value. If only the value is entered, the door-lock device changes to the mode corresponding to the key value.

For example, if the key value is m, set it to 'automatic locking mode'; if the key value is m + 1, set it to 'manual lock mode'; if the key value is m + 2, set it to 'easy open mode', If m + 3, it is set to 'password open mode', if the key value is m + 4, it is set to 'delete all data mode'; if the key value is m + 5, it is set to 'data selection mode', if the key value is m + 6 Set to the 'fingerprint recognition level adjustment mode', and sets the mode specified by the user according to the other key value (m + n) (S38).

At this time, the fingerprint recognition level adjustment mode is a mode for determining how much the user compares when the user authenticates his fingerprint.

Lastly, if the key inputted after the door-lock driving start button is erroneously input, a caution and alarm key tone indicating that an incorrect key is input is generated (S39).

On the other hand, if the door-lock driving start button is described in detail the S4 process when the input from the outside, if the first input fingerprint is the fingerprint of the normal state or the fingerprint of the alarm state to determine whether the fingerprint input in the normal state, The fingerprint is compared with the previously stored fingerprint in the normal state and the fingerprint is opened and the door is opened (S41).

As a result of the determination, when the fingerprint in the alarm state is input, the input fingerprint is compared with the fingerprint in the pre-stored alarm state, and if the fingerprints match, the door is prepared to make an emergency contact (report) at the same time with the salt (S42).

First, it is determined whether the means for emergency contact is wired or wireless communication. In case of wired communication, the telephone is connected through the designated PSTN network. When the phone is connected to send a warning message set in advance to report that someone invaded (S43).

As a result of the determination, if it is wireless communication, it is connected with a designated wireless communication device after radio frequency modulation. When the phone is connected to send a warning message set in advance to report that someone invaded (S44).

As described in detail above, the present invention distinguishes and stores the fingerprint inputted by the user in the normal state and the fingerprint inputted in the alarm state due to the coercion of another person, so even if the door is opened by another person, the report is immediately accepted. The user is not suspicious of others because the door is opened.

If the power of the door-lock system is exhausted, the user has not been using the door-lock for a long time at his or her own discretion. Therefore, the user must be able to determine that the power is depleted and not work. You can use

As described in detail above, the present invention not only increases the number of fingerprint storage in the door-lock system but also introduces an automatic notification service to prevent damage even when the door is forcibly opened by another person. It has the advantage of improving the stability and reliability of the system, has the advantage of preventing cheating by the user by keeping the deleted data in a schedule, and the user can conveniently operate the door-lock device by facilitating the external emergency operation power supply. Make it available.

In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be able to various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications belong to the following claims You will have to look.
