Description

Door opening-shutting and entry person identification method using door opening-shutting system and fingerprint recognition electronic card key}

The present invention provides a door opening and closing system having a door sensor and a door opening and closing method using a fingerprint recognition electronic card key, and more specifically, only a person having a legitimate authority using a fingerprint recognition electronic card key can open the door. The present invention relates to a system and a method for storing and managing the details by checking the identity and access authority of a person who accesses the door after the door is opened.

Door locks in offices, rooms, apartments, and the like, are out of the form of using conventional metal keys. Recently, various technologies have been developed. For example, if a password is entered, the validity of the password can be checked, and the device can be opened through electromechanical operation, or a device that checks the right to open the door by recognizing biometric information such as fingerprint, iris, and voice. Forms of technology are being proposed.

Fingerprints are the most widely used biometric information for identification, and since everyone has a unique fingerprint, it can accurately identify an individual's identity by analyzing them. There is no advantage at all. For this reason, various types of locking devices using fingerprints have been disclosed. Korean Patent Application No. 1996-043141 ("Door Lock Device Using Fingerprint") and Korean Patent Application No. 1997-024920 ("Fingerprint Recognition Door Locking Device) "), And the related art of patent application No. 1999-020851 (" door lock apparatus using fingerprint recognition "), etc. are disclosed.

In the conventional fingerprint recognition lock device, a fingerprint input unit or a fingerprint detection sensor is mounted on a door, and a fingerprint recognition transparent window or a sensing part is exposed to the outside. However, in the optical method using a prism or a hologram, and particularly in the non-optical fingerprint sensing means using a sensor array, an electric field, and an ultrasonic wave, the sensing part is fragile and easily scratched. Because of the drawback of being greatly affected by static electricity, the lifespan or durability of the locking device exposed to the outside is greatly reduced.

In order to compensate for this drawback, Korean Patent Application No. 2000-045072 filed by the same person as the applicant of the present invention provides an electronic card key having a fingerprint input unit and a processor capable of generating a unique code for the input fingerprint. key) to open and close the door. According to this method, the door opening and closing device mounted on the door does not have a fingerprint input unit, and authenticates a user through a fingerprint input using an electronic card key. When the user is authenticated, the electronic card key transmits the stored information (door number openable with the corresponding electronic card key and the fingerprint code of the key manager) to the door opening and closing device (RF transmission), and the door opening and closing device is information stored by the user. The door is opened or closed by comparing the information received from the key.

Using this method, since the fingerprint input unit is disposed on the electronic card key, there is an advantage that the fingerprint recognition sensor is not exposed to the outside to prevent damage. In addition, when the conventional fingerprint recognition device is used in accommodations where the accessor frequently changes, it is cumbersome because the storage contents of the door opening and closing device must be changed every time the user changes. Even if the door does not go to the door equipped with the door opening and closing device, there is an advantage that the remote management is possible because the user can be changed by updating the storage contents (openable door code, administrator fingerprint code) of the portable electronic card key.

However, even with this invention, it is not possible to prevent the case where more than one unauthorized person comes in after the door is first opened. That is, the authorized person could not prevent the unauthorized person from following after the door was opened normally and before the door was closed. Of course, it is necessary to make the shape of the entrance door only accessible to one person, such as a subway ticket gate, and to close the door after one person enters, but this may give a sense of rejection to the user.

Accordingly, the present invention, in the access control method using a fingerprint recognition electronic card key, by using a sensor to check the number of people and / or whether or not to hold the right of the person regardless of the person's intention to control the access of unauthorized persons It was conceived to do.

The present invention has been made in view of the above problems, it is possible to register one or more user fingerprint, user authentication using fingerprint information, can open and close one or more doors, electronic card that can store the access history of the door opening and closing It is intended to provide a key.

In addition, another object of the present invention can be opened and closed using one or more of the above-described electronic card key using the fingerprint information, not only can determine the number of people using the sensor, but also through the transmission and reception of the electronic card key of the person It is an object of the present invention to provide a door opening and closing system that can check the access authority.

Another object of the present invention, by using the above-mentioned fingerprint recognition electronic card key and the door opening and closing device so that only the authorized person can open the door, after the initial opening can confirm and warn that unauthorized persons go in and out. It is to provide a method for opening and closing the door and the person identification.

In this case, data transmission from the electronic card key is performed within a predetermined time in the door closing step. In addition, the door is closed when the sensor unit does not detect an additional person within a predetermined time.

A method (step) of opening a door through data frame transmission between an electronic card key and a door opening and closing device is described in detail in the aforementioned Korean Patent Application No. 2000-045072. Briefly, the administrator inputs the administrator fingerprint code and the accessible door code to the electronic card key and distributes them to the user, and the user registers as a legitimate user by inputting his fingerprint. When a user who wants to open the door receives a user authentication by inputting a fingerprint, the electronic card key transmits the stored door opening data (accessible door code and administrator fingerprint code) to the door opening and closing device. The door opening / closing device checks whether the door code of the door and the received accessible door number match each other, and also determines whether the door is opened by comparing the manager fingerprint code that is selectively transmitted with the manager fingerprint code stored in the door.

In addition to the above-described electronic card key and door opening and closing system, an electronic card key management system as a central control system may optionally be used. The electronic card key management system includes a computer device including a central processing unit, data storage means, a display unit, a data input unit, and a power supply unit, and a built-in or external fingerprint including a data transceiving unit and a fingerprint input unit for transmitting and receiving data with the electronic card key.

One or more codes among the codes are stored in the above-described storage means, and the above-described key management code, one or more access door codes, one or more administrator fingerprint codes, and current date / time information codes by the administrator's command authorized through the administrator fingerprint code. And the above-described reference information data frame consisting of the electronic card key initialization completion code to the electronic card key to be used to manage the electronic card key. In addition, if necessary, the key management system may be linked to all door opening and closing systems.

In the present invention, the "door" for controlling access is a general accommodation room, a door of a residential facility such as an apartment, an office door of a large building, etc., but may also be a door of a transportation means such as a vehicle. If not, for example, it may be installed in the starting portion of the motorcycle without a door and used in the form of a starting control device or the like.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the fingerprint recognition electronic card key, the door opening and closing system, and door opening and closing method using the same.

Figure 1 schematically shows the overall configuration of the system for performing the door opening and closing and access check method using the fingerprint recognition electronic card key and the door opening and closing system according to the present invention.

The entire system includes a fingerprint recognition electronic card key 10 used as a key, a door opening and closing system consisting of a door opening and closing device 20 and a sensor unit 21 mounted on the door 22, and an electronic card key that can be optionally used. It consists of a management system (30). If the authorized user who owns the electronic card key opens the door by transmitting the data frame stored inside the electronic card key to the door opener, the sensor unit counts one or more subsequent users and the door opener is the electronic Ask the cardkey to send a data frame. The door opening / closing device checks whether there is a user who owns an electronic card key without a proper authority and a user who does not own an electronic card key among one or more persons by using the data frame transmitted from the electronic card key and the count result of the sensor unit. Store and manage the entry and exit after warning.

Figure 2 shows a fingerprint recognition electronic card key used in the present invention, Figure 2a shows the overall block diagram, Figure 2b shows the type of data stored in the database.

As shown in FIG. 2A, the electronic card key is connected to a fingerprint recognition unit 213 for recognizing a fingerprint and an external device (external door opening and closing device and electronic card key management system) to transmit and receive information. A data transmission / reception unit 214 including an input / output terminal and an RF transmission / reception unit, a display 211, an input keypad 212, a power supply unit 215, a data storage unit 216, and a controller 210 for controlling them.

The controller 210 uses the image information of the fingerprint recognized by the fingerprint recognition unit 213 to ridge, valley, ending point, bifurcation point, and short of the fingerprint. Feature points such as ridges (short ridge or island), isolation or lake, cross over, etc. are extracted, and the fingerprints are identified using the extracted minutiate, and each fingerprint is identified. Generates unique binary code (fingerprint code). Such a fingerprint recognition and fingerprint code generation function should be provided not only in the electronic card key but also in the electronic card key management system which should receive the fingerprint information of the administrator as described below. These controllers consist of 8-bit or 16-bit microprocessors with counters (or clocks), interrupts, serial or parallel ports, etc., and include an EPROM and a small amount of data memory, a ROM that stores the operating system and basic operating programs. It is a concept.

The controller 210 has a basic function of receiving and storing reference information from a key management system or an administrator, registering a user's fingerprint code, and transmitting a data frame to the door opening and closing system when the user is authenticated. In addition, in order to perform the door opening and closing method according to the present invention, when a data frame transmission request is received from the door opening and closing system, it is necessary to further include a function of transmitting the reference information data frame stored within a predetermined time.

A technique of extracting a fingerprint image and determining whether the same fingerprint is present is a widely used technique, for example, disclosed in US Patent No. 6041133. In addition, a technique for scanning a fingerprint as an image and analyzing a ridge vector of the fingerprint and generating a unique code accordingly is disclosed in US Patent No. 6002787 (fingerprint analysis and encoding method).

The data transmitting / receiving unit 214 is used for exchanging data with a door opening / closing system or a key management system, but may be in the form of a conventional contact magnetic bar. desirable. The data storage unit 216 may be configured of a small capacity (a few kbytes) of flash memory, RAM, or the like.

Such an electronic card key is intended to be used as a "key" in the present invention, but does not necessarily have only an access control function, and functions of a conventional general electronic card, for example, a calculator, an electronic notebook, a simple game machine, and the like. Can be implemented by integrating several functions.

The information stored in the data storage unit 216 of the electronic card key is largely divided into three types, that is, reference information 220, user fingerprint information 230, and access history 240, as shown in FIG. 2B.

The reference information 220 may include a key management code unique to each electronic card key, a fingerprint code information of an administrator, an access door code information, input date and time information of the reference information, and an initialization completion code. Among them, key management code and access door code must be included. The key management code is stored in the EPROM of the electronic card key, and is generally designated since the initial production. However, the key management code may be arbitrarily set by an administrator through, for example, a dip switch. The administrator fingerprint code may be stored by the administrator directly inputting through the electronic card key or by receiving a code stored in the management system. The initialization completion code has a value of 0 or 1, and it is used to determine whether to renew various information of the electronic card key (corresponding to 1) or to accumulate access history by recognizing that the same user continues to use it. Is used.

The user fingerprint code 230 corresponds to a fingerprint code corresponding to a fingerprint input by a user who is legitimate with an electronic card key. When the electronic card key exchanges data with an external door opening and closing device to open or close a door, the card key holder is legally authorized. It is used as a means for authenticating the license. One or more user fingerprint codes can be registered.

The access history information table 240 may include a user, access date and time information, an access door code, and a processing result. The result of the processing is the "User authentication and initial opening" item corresponding to the case where the card key user first opened the authorized door, and the card key owner entering the space where access is not permitted in the form of the companion of the authorized person. “Co-entry (Access to Unauthorized Space)” and the “Co-entry (Access to Permitted Space)” item when the card key user enters or enters a space where the authorized person is allowed to enter. Divided. The situation in which the processing result of each item is generated will be described later with reference to FIG. 6. This entry and exit can be displayed at the request of the user.

Figure 3a is a block diagram of a door opening and closing system mounted on the door (door) to be used in the door opening and closing method according to the present invention. It is composed of a door opening and closing device 20 for opening the door by the exchange of information with the electronic card key and identifying the number of persons and / or the number of persons, and a sensor unit 21 mounted on the door to detect the number of persons. . The door opening and closing device 20 opens and closes the door based on a control signal from the data transmission / reception unit 320, the data storage unit 350, the door opening / closing control controller 310, and the controller to exchange data with the electronic card key. The door opening and closing driving unit 340 and the power supply unit 330 is composed of. The sensor unit 21 is composed of one or more sensors mounted on the door or its surroundings, and determines the number of persons based on the signal from the sensor, and transmits the result to the door opening / closing controller 310 by wire or wirelessly. Has the function.

The door opening / closing controller 310 compares the information received from the electronic card key with some of the data stored in the data storage unit (door code and administrator fingerprint code) to determine whether the door is opened or closed, and identifies the identity and the number of persons. This is to check whether or not the right holder is authorized, and any of the 8051 core 8-bit microprocessor having a counter (or clock), interrupter, serial or parallel port, or 16-bit microprocessor of 68000 core or more It may be used and includes a ROM such as an EPROM in which a program for basic operation of the processor is stored.

The data transmitting / receiving unit 320 is used to exchange data with the electronic card key and / or the sensor unit, and may be in the form of a conventional contact magnetic card reader. It is preferable that it consists of. However, the signal transmission between the sensor unit and the controller may use other means such as wired.

The data storage unit 350 may include a small capacity (a few kbytes) of flash memory, RAM, etc., as shown in FIG. 3B, the door code 360 of the user, the fingerprint code 370 of the registration manager, and the first door. It stores the access history information 380 including information such as the opening date and time, the total number of people, the key management code of the entire number of people, the name of the person, processing results, remarks, and the like for each key management code. Looking at the entry number 381, a user named "Hong Gil-dong" opened the door for the first time using an electronic card key having a management code of "515234", and a total of four visitors came in while the door was opened. Four passengers were identified as the first-opener, Hong Gil-dong, with the card key holder "Kim Chul-soo", the card key holder without permission, "Kim Young-hee", and one unidentified card key smile holder. It became. In the "Remarks" section, two non-authorized persons ("Kim Young-hee" + "Unidentified Box") record a warning that a voice was issued. The total number of visitors is detected through the sensor unit, and whether the card key holder has the authority is made through data frame transmission and reception between the card key and the door opening and closing device, which will be described later with reference to FIG. 6.

The access information stored in the data storage unit of the door open / close device is deleted even if the same key management code is deleted each time the user changes (that is, when the initialization completion code changes from 0 to 1). You can also protect your privacy. However, since the access history information is preferably managed by the administrator and / or the key management system, it is preferable to transmit the stored access information to the key management system to be linked before being deleted. Among the data stored in the data storage unit 350, the door code 360 is stored from the beginning, and the administrator fingerprint information 370 and the access history information 380 may be input or deleted at any time through the electronic card key. .

The door opening / closing driving unit 340 is a device capable of mechanically opening and closing the door according to an opening / closing signal from the controller. The door opening / closing driving unit 340 may include at least one relay driving device and a solenoid driving device. no.

In addition, the door opening and closing device may further include necessary components such as a display unit such as an LCD for showing a processing result or a voice output device including a speaker for outputting a voice warning and the like and an ARS. In addition, the access door code is stored in the EPROM of the door opening and closing device, and is generally designated from the beginning of production. However, the door code may be arbitrarily set by the administrator, for example, via a dip switch.

The sensor unit 21 may be formed of one or more non-contact infrared sensors or light sensors disposed on the upper, lower, left, right, and right doors of the sensor so that the output (voltage or current) of the sensor may be directly input to the door opening / closing controller, based on the signal of the sensor. It may be implemented in the form of a sensor module having an independent function of checking and counting the number of people by itself. The sensor used may be one or more light-blocking sensors disposed in two or more dimensions, or may be one or more non-contact infrared sensors such as a thermopile, but is not limited thereto. Means for sensing the number of users Imaging sensing means such as, for example, an image camera, may be used. However, since the sensor must be able to recognize the user coming in continuously, it is preferable that the response time is short within several ms.

In addition, although not shown, an electronic card key management system may be provided as a central host for overall management of the door opening and closing and accessor identification method according to the present invention. The electronic card key management system includes a computer device including a central processing unit, a data storage unit, a display unit, a data input unit, and a power supply unit, a data transmission / reception unit for transmitting and receiving data with the electronic card key, and a fingerprint input unit. It consists of a fingerprint input device.

The computer device described above has at least one administrator fingerprint code, a key management code input by an administrator authorized using the administrator fingerprint code, one or more access door codes, a user information code of an electronic card key, and information input date and time information. One or more codes among the codes are stored in the above-described storage means, and the above-described key management code, one or more access door codes, one or more administrator fingerprint codes, and current date / time information codes by the administrator's command authorized through the administrator fingerprint code. And a reference information data frame including an electronic card key initialization completion code to the electronic card key to be used to manage the electronic card key. In addition, it is preferable that the electronic card key management system can transmit and receive all door opening and closing devices and / or electronic card keys and data, so that the stored access history can be comprehensively stored and managed.

Figure 4 is a flow chart showing the flow of the first door opening and closing method according to the present invention, and corresponds to a method made using the electronic card key and the door opening and closing system of the present invention. The first door opening and closing and accessing method is largely the administrator fingerprint registration and standard information setting step (S410) by the administrator, the user fingerprint registration step by the electronic card key (S420), the user authentication and door by the electronic card key The information transmission step (S430) to the opening and closing device, the door opening and closing processing step (S440) by the door opening and closing device, and the number of access rights and the number of people after the door opening and access history information storage step (S450). The basic principle of this method is that the user registers the fingerprint on the card key authenticated by the administrator, and when the user wants to open or close the door, the right user inputs his fingerprint to open and close the electronic card key information (door open data frame). It transmits to the device, and compares the information of the electronic card key (access door and administrator fingerprint code) and the information stored in the door opening and closing device to determine the door opening and closing to determine whether the door is opened, In this case, the total number of persons is counted by using the sensor unit, and the access authority of the accompanying persons is checked by using data transmission / reception with the electronic card key.

The present invention focuses on the identification and management of the person after the door is opened, the steps from the above step until the door is opened, that is, the administrator fingerprint registration and information setting step (S410), the user fingerprint registration step (S420) The information transfer step S430 and the door opening and closing step S440 to the door opening and closing device may be used as it is, as described above in Korean Patent Application No. 2000-045072, and thus the detailed description thereof will be omitted.

FIG. 5 is a flowchart illustrating a method of opening and closing a second door according to the present invention and a method of using an electronic card key management system in addition to a fingerprint recognition electronic card key and a door opening and closing system.

The second door opening and closing and access check method is largely the administrator fingerprint registration step to the electronic card key management system (S510), the administrator authentication and electronic card key use information input step (S520), the electronic card key management through the electronic card key management system Reference information transmission step of transmitting the reference information from the system to the electronic card key (S530), reference information storage step of receiving and storing the reference information transmitted by the electronic card key (S540), user fingerprint registration step to the electronic card key (S550) , The user authentication through the electronic card key and the information transfer step to the door opening and closing device (S560), the door opening and closing step (S570) by the door opening and closing device, and the number of access rights and the number of persons and check the history of storage (S580).

The second door opening / closing method is basically similar to the first method, but unlike the first method in which the administrator fingerprint registration and the transfer of the reference information to the electric card key are directly input to the electronic card key, the central host (host The electronic card key management system as) is in charge of this part, and the access authority and the number of persons after the door opening, which is the essence of the present invention, and the access history storing step S580 are performed in the same manner as in the first method. In addition, as in the first method, the steps until the door is opened are the same as those disclosed in Korean Patent Application No. 2000-045072, and thus the detailed description thereof will be omitted.

FIG. 6 illustrates a detailed flow of the access authority and the number of persons after the door is opened and the access history storing step in the above-described first and second methods.

When the door is legitimately opened through the user authentication of the authorized person and the door opening and closing step (S611), the door opening and closing device stores the initial opening time (S612). The door opening and closing device requests to transmit the data frame for authentication (including key management code, administrator fingerprint code, access door code, initialization completion code) to the electronic card key of one or more persons including the first opener ( S613). Since the data frame transmission request is transmitted to the RF transmitter / receiver of the electronic card key through the RF transmitter / receiver of the door opener, the card key can receive the transmission request even if the card key is relatively far from the door switch. Simultaneously with the data frame transmission request, the number of accessors is counted through the access detection sensor unit, and the final access time, which is the time of the last access, is updated (S614).

If the data frame is transmitted from the electronic card key within a predetermined time from the last access time, check that the accessible door code and the user's door code in the contents of the data frame match to ensure that the person who owns the electronic card key has the right to do so. Check if it has (S615, S616). If the sensor detects an additional person within a predetermined time from the last access time (S618), the data frame transmission request is made by using the electronic card key of the person again, the number of accessors is counted, and the final access time is updated (S613 and S614). If the accessor is a person who does not have an electronic card key, the data frame is not received within a predetermined time, and at this time, the identity of the accessor is unknown but an unauthorized person is recorded, and the next step is to check whether there is an accessor. Proceed to S618.

If no additional person is detected within a predetermined time period, it is determined that all persons have entered, and finally, the number of received data frames and the number of detected persons are checked (S619). The card key smiles as an unauthorized person to warn and stores the access history (S620, S621). Of course, warnings may be made after all personnel have entered, but may also be issued whenever an unauthorized person enters or exits. In other words, if authorization is difficult for each person in real time, the data frame transmitted from the electronic card key is stored according to the data frame transmission request, and then the processing result is derived based on the data frame and the total number of people after all the people enter. You can also make a warning.

The final processing result is stored as access history as shown in FIG. 3B (S621), and if necessary, can be recorded on the electronic card key as shown in FIG. 2B. The stored access history (processing result) can be transmitted to the electronic card key management system linked later to be stored and managed, or can be directly confirmed by the administrator.

According to the access information stored and managed, not only the identity of the unauthorized person can be identified (when the resident possesses an electronic card key) but also the first opener who has just opened the door even if the identity of the person is unknown. Since the identity of the accompanying card key smile can be confirmed, the access history can be managed in an integrated manner, and access security can be maintained by preventing theft.

Of course, although not shown, in addition to confirming the accessible door code of the data frame transmitted from the electronic card key, such as when opening the door for the first time in the authorization of the accessor, the step of confirming the administrator fingerprint code is added. It can also be provided as.
