Description

  The present invention relates to an improvement in a door lock system and a door lock release method.

  As a door lock system or a door lock releasing method using a portable terminal such as a mobile phone as a locking / unlocking means instead of a key, it has already been disclosed in "Door Control System" disclosed in Patent Document 1 and Patent Document 2. In addition, the “room entry management method” and the “unlocking method” disclosed in Patent Document 3 have been proposed.

  Among these, the “door control system” disclosed in Patent Document 1 uses the Internet for information communication between the mobile phone and the server, and the server determines the authenticity of the ID transmitted from the mobile phone. Depending on the result, the vending machine door is remotely opened and closed from the server side, and each time the door is opened or closed, it is necessary to access the web page with a mobile phone and enter the ID. Is complicated, the system scale required for opening and closing the door increases, and the operational cost increases. Depending on the communication situation, the time required for the opening and closing operation is redundant. .

  Further, the “room management method” disclosed in Patent Document 2 is different from the above “door control system” in that the door to be opened and closed is a door of a building or the like. In that the processing operation is performed using the above, it is the same as that of Patent Document 1, and as described above, problems such as the point that the scale of the system becomes large and the time required for the opening / closing operation are delayed cannot be solved.

  The “unlocking method” disclosed in Patent Document 3 is a technique for dull check that is used in combination with biometric detection type authenticity determination such as fingerprint matching. In this "unlocking method", information can be exchanged between the mobile phone and the lock device using weak radio waves, so it is not always necessary to connect to the Internet. A program, a circuit, or the like for transmitting authentication information in response to a call needs to be installed on the mobile phone side, and a cost problem still remains.

  Furthermore, a keyless entry system is known in which a transmitter is incorporated in a vehicle key and authentication information is transmitted to the vehicle by operating a push switch or the like provided on the key to release the door lock. This is not a problem in terms of speed, simplicity, and cost required for providing services, but has insufficient security measures against theft when keys are lost.

  Accordingly, an object of the present invention is to improve the inconvenience of the prior art, without increasing the scale of the system required for opening and closing the door, and the time required for the opening and closing operation is not redundant, and the loss of the portable terminal instead of the key is lost. It is an object of the present invention to provide a door lock system and a door lock release method that can cope with the above.

The door lock system according to the present invention includes a data input means for inputting data, a storage means for storing the input data, and a proximity for transmitting the data stored in the storage means to another device. A door lock system comprising a mobile terminal provided with a wireless communication means for distance communication and a door lock device having an electric lock mechanism, and in order to achieve the above-mentioned problem,
The door lock device is
Receiving means for receiving data transmitted from the wireless communication means of the portable terminal;
User authentication information storage means storing an initial setting value of user authentication information required for unlocking the door;
A lock release determination unit that compares the data received by the reception unit with the user authentication information stored in the user authentication information storage unit and releases the door lock by the lock mechanism only when they match. When,
Authentication data input means for inputting data including authentication information;
The data input by the authentication data input means is compared with the user authentication information stored in the user authentication information storage means, and only when both match, the authentication data input means And a user authentication information rewrite determination unit that allows rewriting.

The user refers to the initial setting value of the user authentication information taught by the manufacturer or dealer at the time of shipment of the door lock device, operates the data input means of the portable terminal, and stores the initial setting value in advance in the portable terminal. It is memorized in the means.
Then, the user who has the mobile terminal operates the short-range communication wireless communication means in the vicinity of the door lock device, and transmits the data stored in the storage means of the mobile terminal, that is, the initial setting value of the user authentication information Then, this data is received by the receiving means of the door lock device.
Next, the unlock determination means of the door lock device is activated, and the data received by the receiving means is compared with the user authentication information stored in the user authentication information storage means. Release the door lock by the lock mechanism.
Since the initial setting values of the user authentication information are stored in both the user authentication information storage unit of the door lock device and the storage unit of the portable terminal at the stage immediately after the start of use of the door lock device, they match, The door lock by the electric lock mechanism is released by the lock release determination means of the lock device.
On the other hand, when the user inputs data by operating the authentication data input means of the door lock device, the user authentication information rewrite determination means of the door lock device is activated, and the data input by the authentication data input means and the user The user authentication information stored in the authentication information storage unit is compared, and the user authentication information is rewritten by the authentication data input unit only when they match.
In the stage immediately after the start of use of the door lock device, the user authentication information storage means of the door lock device stores the initial setting value of the user authentication information, and this initial setting value is taught by the manufacturer. The user can freely rewrite the user authentication information stored in the user authentication information storage means. For example, the initial setting value of the user authentication information can be rewritten to user authentication information that is easy for the user to remember. It is virtually impossible for a third party who does not know the initial setting value of the user authentication information to rewrite the user authentication information.
When the user authentication information is rewritten, the user operates the data input means of the portable terminal in the same manner as described above, and stores the user authentication information as a result of the rewriting in the storage means of the portable terminal. As a result, the user authentication information stored in the user authentication information storage means of the door lock device again matches the user authentication information stored in the storage means of the mobile terminal, and the wireless communication means of the mobile terminal The door lock release operation using is continuously allowed.
If the user loses the portable terminal owned by the user in any way, the user immediately operates the authentication data input means of the door lock device in the same manner as described above and is stored in the user authentication information storage means. The user authentication information is rewritten with another user authentication information. As a result, the user authentication information currently stored in the user authentication information storage means of the door lock device and the user authentication information currently stored in the storage means of the mobile terminal are in a mismatched state. Even if a lost mobile terminal is handed over, a door lock release operation by a third party who has stolen the mobile terminal is prevented.
As mentioned above, access to the web page and manual input of user authentication information are not required when unlocking the door, so the door unlocking operation is extremely simple, and the use of an Internet connection or server is also possible. Since it is unnecessary, the system is small in scale and does not require maintenance costs, and there is no problem of redundancy in waiting time due to deterioration in communication status, and a general mobile terminal equipped with a short-range communication wireless communication means Since the basic functions are used, there is no need to install special programs or circuits on the mobile terminal. Furthermore, even if the mobile terminal that replaces the key is lost, the door locks due to theft of the mobile terminal Can be prevented in advance.

In addition to the above configuration,
An authentication information storage means for administrator storing an initial setting value of the authentication information for administrator;
The data input by the authentication data input means is compared with the administrator authentication information stored in the administrator authentication information storage means, and the data input by the authentication data input means is the administrator authentication information. An administrator authentication information rewrite determination unit that permits rewriting of the administrator authentication information and rewriting of the user authentication information only when they match, may be provided.

  By using a comparison process using administrator authentication information, only the appropriate administrator can rewrite the administrator authentication information and the user authentication information, so that the administrator authentication information and the user authentication information can be rewritten. Security is guaranteed. Furthermore, by allowing the administrator to rewrite the user authentication information, the user who caused the disqualification can be prohibited from releasing the door lock device. The application of the system can be extended to doors that are premised on the entry and exit of a large number of users, for example, doors of rental housing, public facilities, or companies.

  In this way, when the application target of the door lock device is extended to a door premised on the entry and exit of an unspecified number of users, the user authentication information is configured with a key number and a user password. It is desirable that the user authentication information rewrite determination means is configured to permit only rewriting of the user password.

  Even if the user rewrites the user authentication information, the key number in the user authentication information remains as it is, so that the administrator can easily identify the original user and check the change history of the user authentication information. Therefore, even when the user rewrites the user authentication information, if the user is disqualified, the user's operation to release the door lock device can be surely restricted.

Further, the administrator authentication information is constituted by the key number and the administrator password, and an expiration date storage area for storing the expiration date of the key number corresponding to the administrator authentication information is provided. And provided in
The expiration date corresponding to the key number is obtained from the administrator authentication information storage means based on the key number of the user authentication information, and the door lock is released only when the current time is within the expiration date. You may comprise a lock release determination means.

  The use of user authentication information is automatically restricted by the expiration date set by the administrator, so rewriting the user authentication information required when the user can release the door lock by determining the expiration date No operation is required, and the administrator's trouble is reduced.

  It is desirable to use a mobile phone as a mobile terminal that is a component of the door lock system.

Notepad data (text data), address book data (array data), schedule data (array data), saved mail data (text data), image data (raster data) stored in the mobile phone storage means ) And the like are already known in the art for transmitting to other devices such as a personal computer.
Since the user authentication information is composed of a simple character string (text data), the user authentication information is stored in the storage means in a non-volatile manner using a keyboard of a mobile phone that functions as a data input means. If the user authentication information is transmitted to the door lock device which is another device by the short-range communication wireless communication means provided in the mobile phone, for example, in the same manner as the data of the memo pad, It can be used as a portable terminal of a door lock system without any changes to programs and circuits. Similarly, a PDA or other device can be used as a portable terminal.

  The wireless communication means and the reception means are preferably compliant with infrared communication based on the IrDA standard.

  Although the use of Bluetooth or the like is possible, since the communication range by infrared communication is narrower, the use of infrared communication is appropriate for preventing eavesdropping of user authentication information.

The door lock releasing method of the present invention achieves the same problem as described above,
User authentication information is stored in advance in a door lock device that locks the door and a portable terminal carried by the user,
When user authentication information is wirelessly input from the mobile terminal to the door lock device, the user authentication information received by the door lock device is compared with the user authentication information stored in the door lock device. And only when both coincide, the door lock by the door lock device is released,
When user authentication information is manually input to the door lock device, the user authentication information is compared with the user authentication information stored in the door lock device, and only when both match. The user authentication information stored in the door lock device is allowed to be rewritten, and at the same time, the user authentication information that is the result of rewriting is updated and set in the portable terminal.

  As already mentioned, access to the web page and manual entry of user authentication information are not required when unlocking the door, so it is extremely easy to unlock the door and use an Internet connection or server. Since it is unnecessary, the system is small in scale and does not require maintenance costs, and there is no problem of redundancy in waiting time due to deterioration in communication status, and a general mobile terminal equipped with a short-range communication wireless communication means Since the basic functions are used, there is no need to install a special program or circuit on the mobile terminal, and even if the mobile terminal that replaces the key is lost, the door lock by theft of the mobile terminal Can be prevented in advance.

Furthermore, the initial setting value of the authentication information for the administrator is stored in the door lock device,
When the authentication information for administrator is manually input to the door lock device, the authentication information for administrator is compared with the authentication information for administrator stored in the door lock device. For example, the administrator authentication information stored in the door lock device can be rewritten and the user authentication information can be rewritten.

  By using a comparison process using administrator authentication information, only the appropriate administrator can rewrite the administrator authentication information and the user authentication information, so that the administrator authentication information and the user authentication information can be rewritten. Security is guaranteed, and by allowing the administrator to rewrite user authentication information, users who have been disqualified can be prohibited from unlocking the door lock device. This door lock releasing method can be applied to doors that are premised on the entry / exit of an unspecified number of users, such as rental housing, public facilities, or office doors.

  In addition, when the user authentication information is configured by a key number and a user password, and the user authentication information manually input to the door lock device matches the user authentication information stored in the door lock device It is desirable to adopt a configuration that allows only rewriting of the user password.

  Even if the user rewrites the user authentication information, the key number in the user authentication information remains as it is, so that the administrator can easily identify the original user and check the change history of the user authentication information. Therefore, when disqualification matters arise for the user, it is possible to reliably limit the user's operation to release the door lock device.

Further, the door lock device stores the expiration date of the key number in association with the administrator authentication information,
When releasing the door lock by the door lock device, the expiration date corresponding to the key number is obtained based on the key number of the user authentication information input wirelessly, and the door is locked only when the current time is within the expiration date. It is good to comprise so that it may cancel.

  The use of user authentication information is automatically restricted by the expiration date set by the administrator, so rewriting the user authentication information required when the user can release the door lock by determining the expiration date No operation is required, and the administrator's trouble is reduced.

The door lock system and the door lock release method according to the present invention store the user authentication information in the door lock device and the user's portable terminal in advance, and use the short distance communication wireless communication means provided in the portable terminal to lock the door lock. By transmitting the user authentication information to the device, the user authentication information transmitted from the portable terminal is compared with the user authentication information stored in the door lock device, and only when the two match, the electric type Since the door lock by the lock mechanism is released, access to the Web page and manual input operation of user authentication information are not required when releasing the door lock. Accordingly, the door lock release operation is extremely simple, and there is no need for internet connection or use of a server. Therefore, the scale of the system is small, and a general mobile phone equipped with wireless communication means for short-range communication is also available. Since the basic function of the terminal is used, it is not necessary to install a special program or circuit on the portable terminal, so there is no maintenance cost, and the problem of waiting time redundancy due to deterioration of the communication status is also solved.
Furthermore, when user authentication information is input from the authentication data input means of the door lock device, the data input by the authentication data input means is compared with the user authentication information stored in the door lock device, Since the user authentication information for the user is allowed to be rewritten only when the two match, even if the mobile terminal owned by the user is lost due to some trouble, Stealing a lost mobile terminal by rewriting the stored user authentication information so that the user authentication information on the door lock device and the user authentication information stored on the lost mobile terminal do not match It is possible to prevent a door lock release operation by a third party.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a door lock system according to an embodiment to which a door lock releasing method of the present invention is applied.

  This door lock system 1 includes a mobile phone 2 which is a kind of mobile terminal provided with short-range wireless communication means, and a door lock device 4 for fixing an openable or slidable door 3 to a door frame or the like. Composed.

  Among these, the mobile phone 2 transmits a keyboard functioning as a data input unit, a non-volatile memory that is a storage unit for storing input data, and data stored in the non-volatile memory to other devices. An infrared communication device of IrDA standard that functions as a short-range communication wireless communication means.

  In this embodiment, the keyboard of the mobile phone 2 is used for inputting and rewriting user authentication information, the non-volatile memory is used for storing user authentication information, and the infrared communication device is stored in the non-volatile memory. Although it will be used for transmitting stored user authentication information, these data input function, data storage function, and data transmission function are common in mobile phones equipped with infrared communication devices. The program, circuit, etc. for adapting the cellular phone 2 to the door lock system 1 of the embodiment are not required.

  For example, a technique for transmitting text data of a memo pad stored in a mobile phone to a personal computer or the like by infrared communication is known. Specifically, for example, a memo pad function is selected from an accessory program of a mobile phone. If the user authentication information is input from the keyboard, this data is stored in a non-volatile memory as a notepad file, and transmission processing by the infrared communication device is performed on this file as a transmission target, the mobile phone 2 receives The stored user authentication information can be transmitted to the door lock device 4 without difficulty.

  Since the configuration and functions relating to this type of mobile phone are already known, detailed description of the mobile phone 2 itself is omitted.

  An outline of the configuration of the door lock device 4 is shown in the functional block diagram of FIG. The door lock device 4 of this embodiment includes an electric lock mechanism 5, receiving means 6 for receiving data transmitted from the infrared communication device of the mobile phone 2, and unlocking the door 3 by the lock mechanism 5. User authentication information storage means 7 storing initial setting values of user authentication information required for the user authentication, data received by receiving means 6 and user authentication stored in user authentication information storage means 7 Only when the information is compared and the two match, the unlock determination means 8 for releasing the door lock by the lock mechanism 5, the authentication data input means 9 for inputting data including authentication information, and the authentication data The data input by the input means 9 and the user authentication information stored in the user authentication information storage means 7 are compared, and the authentication data input procedure is performed only when they match. 9, in addition to the user authentication information rewrite determination means 10 that allows the user authentication information to be rewritten, the administrator authentication information storage means 11 that stores the initial setting value of the administrator authentication information, and authentication data input When the data input by the means 9 is compared with the authentication information for administrator stored in the authentication information storage means 11 for administrator and the data input by the authentication data input means 9 matches the authentication information for administrator For example, an administrator authentication information rewrite determination unit 12 that permits rewriting of the administrator authentication information in the administrator authentication information storage unit 11 and rewrite of the user authentication information in the user authentication information storage unit 7 is provided.

  FIG. 3 is a block diagram showing an outline of the hardware configuration of the door lock device 4. The door lock device 4 includes a CPU 13 for arithmetic processing, a ROM 14 storing a control program for the CPU 13, a RAM 15 used for temporary storage of arithmetic data, a user authentication information storage means 7 and an administrator authentication information memory. A nonvolatile memory 16 functioning as the means 11 is provided.

  The input / output circuit 17 of the CPU 13 includes a numeric keypad (including alphabetic keys) 19 that functions as the authentication data input unit 9, an infrared receiver 21 that functions as the reception unit 6, and an electric motor that functions as the lock mechanism 5. The driver 23 of the lock 22, the display 20 for displaying a guidance message related to the operation of the door lock device 4, and the start of verification for declaring the start of data transfer by infrared communication to the door lock device 4 (CPU 13) The switch 18a and an access key 18b for declaring the start of data input by the numeric keypad 19 to the door lock device 4 (CPU 13) are connected.

  Operation signals from the verification start switch 18a and the access key 18b and user authentication information and administrator authentication information input via the numeric keypad 19 are read into the CPU 13 via the input / output circuit 17 and received by the infrared receiver 21. The user authentication information thus read is also read into the CPU 13 via the input / output circuit 17. The infrared receiver 21 is normally in an inoperative state, and waits for data transmission from the mobile phone 2 for a predetermined time after the operation of the collation start switch 18a. The electric lock 22 is driven and controlled by the CPU 13 via the driver 23 and the input / output circuit 17, and is switched between a locked state in which the door 3 is fixed to the door frame or the like and an unlocked state in which the door 3 is opened and closed. In addition, a guidance message or the like corresponding to the operation state of the door lock device 4 is displayed on the display 20 under the control of the CPU 13 side.

  The CPU 13 functions as the lock release determination means 8, the user authentication information rewrite determination means 10, and the administrator authentication information rewrite determination means 12 in the present embodiment, and a program for causing the CPU 13 to function as these means is previously stored. It is stored in the ROM 14 (see FIGS. 11 to 15).

  Although not particularly shown here, an internal clock using a clock generator for controlling the operation timing of the CPU 13 is provided, and the CPU 13 refers to this internal clock and confirms the current value of year / month / day / hour / minute / second. can do.

  An example of the administrator authentication information storage file constructed in the nonvolatile memory 16 functioning as the administrator authentication information storage means 11 is shown in the conceptual diagram of FIG. 4 and the nonvolatile information functioning as the user authentication information storage means 7. An example of the user authentication information storage file constructed in the memory 16 is shown in the conceptual diagram of FIG.

  As shown in FIG. 4, in this embodiment, the administrator authentication information is configured by a combination of the key number and the administrator password, and is provided corresponding to the administrator authentication information. The expiration date of the key number is stored in the expiration date storage area. Of these, the initial setting value of the administrator authentication information is stored in the first address of the administrator authentication information storage file by the processing operation of the manufacturer at the time of shipment of the door lock device 4. However, a manager having appropriate authority is notified in advance by e-mail or mailing of documents.

  When the administrator authentication information storage file in FIG. 4 is accessed, the data input by the numeric keypad 19 may match the administrator authentication information stored in the administrator authentication information storage file. Since it is indispensable, only an administrator with appropriate authority is allowed to access the administrator authentication information storage file.

  The administrator who is permitted to access the administrator authentication information storage file directly operates the numeric keypad 19 for both the administrator authentication information storage file and the user authentication information storage file of FIG. Can be rewritten, updated, or deleted. Since the contents of the “other optional information” column are not information related to the direct processing operation, it is possible to freely store the communication items and memorandums.

  The user authentication information in this embodiment is composed of a combination of a key number and a user password as shown in FIG. The initial address of the user authentication information set by the above-mentioned administrator is stored at the first address of the user authentication information storage file. This initial value is the same as described above, such as e-mail or mailing of documents. The administrator notifies the user who has appropriate rights.

  When accessing the user authentication information storage file, it is essential that the data input by the numeric keypad 19 matches the user authentication information stored in the user authentication information storage file. Only the user having an appropriate right and the above-mentioned administrator are allowed to access the authentication information storage file.

  A user who is permitted to access the user authentication information storage file can directly perform processing such as rewriting or updating the contents of the user authentication information storage file by operating the numeric keypad 19. However, only the portion of the user password in the user authentication information is allowed to be rewritten or updated. Since the contents of the “Contact” and “Other optional information” fields are not information related to the direct processing operation, it is possible to freely store contact items, memorandums, and the like.

  Next, processing operations of the CPU 13 functioning as the lock release determination unit 8, the user authentication information rewrite determination unit 10, and the administrator authentication information rewrite determination unit 12 will be described with reference to the flowcharts of FIGS.

  However, at this stage, only the initial setting value of the administrator authentication information is stored in the administrator authentication information storage file of FIG. 4, and nothing is stored in the user authentication information storage file of FIG. To do.

  First, when the door lock device 4 is installed on the door 3 and the door lock device 4 is turned on, the CPU 13 initializes the values of the retry counter C and the selection completion flag F to 0 (step S1). Then, an initial standby state for waiting for an operation of the access key 18b or the collation start switch 18a is entered (steps S2 and S3).

When the operation of the access key 18b is detected in the determination process of step S2, the CPU 13 restarts the timer T that measures the allowable operation time and starts measuring the elapsed time after the access key operation (step S4). A guidance message for password entry as shown in FIG. 8 is displayed on the display 20 (step S5), and the input of a password using the numeric keypad 19 functioning as the authentication data input means 9 or the time-up of the timer T is awaited. A standby state is entered (step S6, step S7).
The access key 18b is not necessarily provided independently of the numeric keypad 19, and may be configured to display the guidance message of FIG. 8 when any numeric keypad 19 is first operated. In that case, the numeric keypad 19 functions as the access key 18b.

  However, the password here is a concept that combines administrator authentication information and user authentication information.

  Here, if the determination result in step S7 is true, that is, if the password is not input within the allowable operation time, the CPU 13 determines that the operation of the access key 18b is due to an erroneous operation or mischief. Assuming that there is, the guidance message display is cleared (step S8), and the initial standby state is restored again.

  If the determination result in step S6 is true and password input is confirmed, the CPU 13 functioning as the user authentication information rewrite determination means 10 and the administrator authentication information rewrite determination means 12 is shown in FIG. The administrator authentication information storage file and the user authentication information storage file in FIG. 5 are searched, and it is determined whether the administrator authentication information or the user authentication information that matches the password is stored in any file. (Step S9, Step S26).

  As described above, at this stage, only the initial setting value of the administrator authentication information is stored in the administrator authentication information storage file of FIG. 4, and nothing is stored in the user authentication information storage file of FIG. Therefore, these determination results are true only when the administrator inputs the appropriate administrator authentication information, that is, the initial setting value of the administrator authentication information.

  If both the determination results of step S9 and step S26 are false and an illegal password input is detected, the CPU 13 displays an illegal input alert message on the display 20 and increments the value of the retry counter C by one. (Step S27, Step S28), it is determined whether or not the current value of the retry counter C has reached the retry limit value N (set value) (Step S29).

  Here, if the current value of the retry counter C has not reached the retry limit value N, the CPU 13 considers that the unauthorized input of the password is due to a non-malicious operation, and sets a timer T for measuring the allowable operation time. The guidance message for password entry is displayed again (step S4, step S5), and a standby state is entered to wait for the password input or timer T to expire (step S6, step S7).

  When the current value of the retry counter C reaches the retry limit value N, the CPU 13 considers that the illegal input of the password is due to obvious illegal acts, and an alarm device or security company provided separately. An abnormality handling process such as activating an alarm device is performed (step S30), the value of the retry counter C is initialized (step S31), the alert message display is cleared (step S8), and the initial value is reset. Return to standby state.

  On the other hand, when the administrator inputs the initial setting value of the authentication information for administrator, which is the only appropriate authentication information for administrator at that time, as the password, the determination result in step S9 becomes true, and the CPU 13 The timer T for measuring the allowable time is restarted to start measuring the elapsed time after the password is input (step S10), and a manager guidance message as shown in FIG. 9 is displayed on the display 20 (step S11). ), A standby state is entered to wait for the input of the menu number using the numeric keypad 19 or the time-up of the timer T (step S12, step S18, step S19).

  As described above, since the value of the selection completion flag F is currently held at the initial value 0, the determination result in step S19 is constantly false.

  If the determination result in step S18 is true, that is, if the administrator does not input the menu number within the allowable operation time, the CPU 13 intends to perform a file operation on this administrator. In the state where the selection completion flag F is kept at the initial value 0 (step S22), the display of the guidance message for the administrator is cleared (step S8), and the initial standby is performed again. Return to the state.

  On the other hand, when an administrator who refers to the administrator guidance message displayed on the display 20 operates the numeric keypad 19 and inputs one of the menu numbers “011”, “012”, “013”, this operation is performed. Is detected by the CPU 13 in the determination process of step S12.

  However, “011” is a menu number for requesting access to the administrator authentication information storage file of FIG. 4, and “012” requests access to the user authentication information storage file of FIG. "013" is a menu number for requesting writing to the "other optional information" column in the administrator authentication information storage file of FIG.

  In this way, the CPU 13 that has detected the input of the menu number in the determination process of step S12 sets the selection completion flag F to 1 and stores the completion of the menu selection (step S13). It is determined whether it is “011” or “013” or “012” (step S14, step S23).

  If the value of the menu number is not one of them, it means that the menu number has been input incorrectly, so the CPU 13 displays an input error message on the display 20 and sets the selection completion flag F. The value is initialized to 0 again (steps S24 and S25), and the guidance message for the manager as shown in FIG. 9 is redisplayed on the display 20 (step S11), and the menu number is input or the timer T is timed up. (Step S12, Step S18, Step S19).

  On the other hand, when the input of the menu number “011” or “013” is confirmed in the determination process in step S14, the CPU 13 reads the administrator authentication information storage file shown in FIG. The contents of the administrator authentication information storage file are temporarily stored in the RAM 15 and displayed on the display 20 (step S15). Then, the CPU 13 functions as the administrator authentication information rewrite determination means 12 until the administrator operates the END key in the numeric keypad 19 to declare completion of the input processing or until the timer T expires. However, processing such as rewriting, updating, and deletion of the contents of the administrator authentication information storage file on the RAM 15 performed based on the operation of the numeric keypad 19 is continuously permitted (steps S16 to S19).

  As described above, since the value 1 is already set in the selection completion flag F at the present time, the determination result in step S19 is constantly true.

Regarding the rewriting of the administrator authentication information, specifically, assuming that a single administrator manages the administrator authentication information storage file, the change result is changed to the first address of the administrator authentication information storage file. Overwrite a certain administrator authentication information, and update the administrator authentication information without leaving the previous change history (in this case, the administrator authentication information input via the numeric keypad 19 after the change is always the first The administrator authentication information stored in the address is compared), or the administrator authentication information that is the result of the change is premised on the assumption that a single administrator manages the administrator authentication information storage file. Stores the next empty address, uses only the administrator authentication information stored in the latest address as valid administrator authentication information, and manages the previous administrator authentication information as the change history. Can be left in the administrator authentication information storage file (in this case, the administrator authentication information input via the numeric keypad 19 after the change is always compared with the administrator authentication information stored in the latest address). .
Alternatively, on the assumption that a plurality of administrators manage the administrator authentication information storage file, each time the initial setting value stored in the first address of the administrator authentication information storage file is input, the next empty The administrator authentication information that is the change result, that is, the newly registered administrator authentication information is stored in the address, and the administrator authentication information that matches the administrator authentication information of each address is newly added below. Each time an input is made, the administrator authentication information of the relevant address is overwritten and the administrator authentication information of each administrator is updated independently (in this case, for the administrator input via the numeric keypad 19 after the change) The authentication information is compared with the administrator authentication information stored at all addresses). Furthermore, the administrator is a change result on the assumption that a plurality of administrators manage the administrator authentication information storage file. Authentication information is stored in the next empty address in order, and only the administrator authentication information stored in the latest address is used as valid administrator authentication information, and each previous administrator authentication is used. Information is left as a change history in the administrator authentication information storage file for each administrator (in this case, the administrator authentication information input via the numeric keypad 19 after the change is always stored at the latest address) (Compared with administrator authentication information of the administrator) is also possible.

  In either case, the administrator reissues the manager's PIN number to a password that is easy to remember, then issues a new key number corresponding to his / her PIN and sets the corresponding expiration date. An expiration date corresponding to the key number used by the user who has been disqualified, or is re-set in the expiration date storage area, or only the administrator PIN is rewritten to ensure security. Can be rewritten to substantially invalidate the use of the key. In addition, when leaving a change history in the administrator authentication information storage file, the validity period set corresponding to the latest administrator authentication information is set to the valid period set corresponding to the administrator authentication information of the previous generation. You may set so that it may overlap with a time limit, and in that case, two authentication information for managers will become effective within the overlapping expiration date. If there is no security problem, the administrator password and key number included in the administrator authentication information, which is the initial setting value, may be used as they are.

  However, in the case where a plurality of administrators manage the authentication information storage file for administrators, if it is necessary to ensure the security between the administrators, the figure read out in the process of step S15 and temporarily stored in the RAM 15 4, the administrator authentication information storage file shown in FIG. 4 is not displayed on the display 20, and the administrator authentication information rewriting process performed after the administrator registration, that is, the administrator authentication that is an initial setting value is performed. When the administrator authentication information is rewritten by the administrator who has entered the information and acquired the storage area for the administrator authentication information unique to the user at a specific address in the administrator authentication information storage file, for example, FIG. As shown in FIG. 4, only the contents of the administrator authentication information whose address matches the administrator authentication information input as the password are displayed on the display 20. So as to.

  Finally, when the administrator operates the END key in the numeric keypad 19 to declare the completion of the input process, the CPU 13 detects this operation in the determination process of step S17, and the administrator authentication information storage file on the RAM 15 4 is overwritten and stored in the administrator authentication information storage file in the nonvolatile memory 16 to update the content of the administrator authentication information storage file in FIG. 4 (step S20), and an end message is displayed on the display 20 Then, the value of the selection completion flag F is initialized to 0 (steps S21 and S22), the display of the end message is cleared (step S8), and the initial standby state is restored. As described above, writing in the “other optional information” column corresponding to the menu number “013” is optional.

  If the input of the menu number “012” is confirmed in the determination process in step S23, the CPU 13 reads the user authentication information storage file shown in FIG. 5 from the nonvolatile memory 16 and temporarily stores it in the RAM 15. The contents of the user authentication information storage file are displayed on the display 20 (step S32). Then, the CPU 13 functions as the administrator authentication information rewrite determination means 12 until the administrator operates the END key in the numeric keypad 19 to declare completion of the input processing or until the timer T expires. Continues to permit processing such as rewriting, updating, and deleting the contents of the user authentication information storage file on the RAM 15 performed based on the operation of the numeric keypad 19 (steps S33 to S35).

  Regarding rewriting of user authentication information, the administrator first creates user authentication information by combining the key number issued by the user with an arbitrary user PIN generated by the administrator. The initial setting value is written in the user authentication information storage file on the RAM 15. Since the number of users who use the door 3 is not limited to one, usually, a plurality of user authentication information is created and these user authentication information are written in the user authentication information storage file on the RAM 15.

  When the administrator finally operates the END key in the numeric keypad 19 to declare the completion of the input process, the CPU 13 detects this operation in the determination process of step S34 and stores the user authentication information on the RAM 15. The contents of the user authentication information storage file in FIG. 5 are registered or updated by overwriting the contents of the file on the user authentication information storage file in the nonvolatile memory 16 (step S37), and an end message is displayed on the display 20. This is displayed and the value of the selection completion flag F is initialized to 0 (steps S38 and S36), the display of the end message is cleared (step S8), and then the initial standby state is restored.

  However, in the case where a plurality of administrators use the same user authentication information storage file, if it is necessary to ensure security between the administrators, the figure read out in the process of step S32 and temporarily stored in the RAM 15 The user authentication information storage file shown in FIG. 5 is not displayed on the display 20, and is issued by the user authentication information having the key number that matches the key number of the input administrator authentication information. Only the user authentication information of the user having the key number is displayed on the display 20.

  The administrator notifies each user of the initial setting value of the created user authentication information and the expiration date thereof by e-mail or mailing of documents. If the user is an administrator without an administrator, the manufacturer, dealer, etc. set these initial setting values at the time of shipment of the door lock device 4, and send an e-mail to the user. Each user will be notified by mailing documents.

  The user can use this initial set value as user authentication information as it is, or can rewrite and use the user PIN number in consideration of ease of remembering and security.

  When the user rewrites the user password in the user authentication information, the user operates the access key 18b of the door lock device 4 in the same manner as described above (see step S2), and the numeric keypad that functions as the authentication data input means 9 19 is used to input user authentication information as a password to the door lock device 4 (see step S6).

  The user authentication information input in this way is stored in the administrator authentication information storage file of FIG. 4 and FIG. 5 by the CPU 13 functioning as the user authentication information rewrite determination means 10 and the administrator authentication information rewrite determination means 12. Are compared with all the valid authentication information stored in the user authentication information storage file (step S9, step S26), that is, when the user inputs proper user authentication information, that is, the user authentication information of FIG. When valid user authentication information already stored in the storage file is input to the storage file, the determination result in step S26 is true, and the CPU 13 first sets a key constituting a part of this user authentication information. The administrator authentication information storage file of FIG. 4 is searched based on the value of the number, and the expiration date stored corresponding to the key number is obtained (step Flop S39), further obtains the current value of the date, hour, minute, and second with reference to the internal clock, and determines whether or not the key number is valid at the present time (step S40).

  Here, if the determination result in step S40 is false, that is, if it is determined that the key number is invalid, the user has no right to open and close the door 3 in the first place, and for the user. Since it is meaningless to allow the password to be rewritten, the CPU 13 clears the guidance message display (step S8) and returns to the initial standby state again.

  As described above, since an administrator having appropriate administrator authentication information can operate the user authentication information storage file in FIG. 5, the administrator manually operates the user authentication information or the user authentication information. When a part of the above is rewritten or deleted, the determination result in step S26 is false, and the processes in steps S39 to S55 are not executed. In other words, the administrator can automatically restrict the user's right by setting the validity period, or can restrict the user's right by rewriting the manual operation on the user authentication information. The former is the automatic extinction of rights based on the initial contract, and the latter means the forcible revocation of rights due to the occurrence of disqualification due to unforeseen circumstances.

  On the other hand, if the determination result in step S40 is true, that is, if it is determined that the user authentication information is appropriate and the key number is valid, the CPU 13 The timer T for measuring the allowable time is restarted to start measuring the elapsed time after the password is input (step S41), and a user guidance message as shown in FIG. 10 is displayed on the display 20 (step S42). Then, a standby state is entered to wait for the input of the menu number using the numeric keypad 19 or the time-up of the timer T (step S43, step S49, step S50).

  At this time, since the value of the selection completion flag F is held at the initial value 0, the determination result in step S50 is constantly false.

  Here, if the determination result in step S49 is true, that is, if the user does not input the menu number within the operation allowable time, the CPU 13 does not intend to perform the file operation on this user. With the selection completion flag F held at the initial value 0 (step S51), the display of the user guidance message is cleared (step S8), and the initial standby state is restored.

  On the other hand, when the user who refers to the user guidance message displayed on the display 20 operates the numeric keypad 19 to input one of the menu numbers “021” and “022”, this operation is determined in step S43. Is detected by the CPU 13.

  However, “021” is a menu number for requesting access to the user authentication information storage file of FIG. 5, and “022” is written in the “Contact” and “Other optional information” fields. The menu number to request.

  In this manner, the CPU 13 that has detected the input of the menu number in the determination process of step S43 sets the value 1 to the selection completion flag F and stores the completion of the menu selection (step S44). Whether it is “021” or “022” is determined (step S45).

  If the value of the menu number is not one of them, it means that the menu number has been input incorrectly, so the CPU 13 displays an input error message on the display 20 and sets the selection completion flag F. The values are initialized again (steps S54 and S55), and the user guidance message as shown in FIG. 10 is displayed again on the display 20 (step S42), and waiting for the input of the menu number or the time-up of the timer T is awaited. The state is entered (step S43, step S49, step S50).

  On the other hand, when the input of the menu number “021” or “022” is confirmed in the determination process of step S45, the CPU 13 reads the user authentication information storage file shown in FIG. Only the contents of the user authentication information of the user who has temporarily stored and entered the user authentication information in the current operation are displayed on the display 20 as shown in FIG. 7, for example (step S46). The CPU 13 functioning as the user authentication information rewrite determining means 12 until the user declares completion of input processing by operating the END key in the numeric keypad 19 or the timer T expires, Of the user authentication information stored in the user authentication information storage file on the RAM 15, only for the portion of the user password in the user authentication information of the user who has input the user authentication information in this operation, The rewriting or updating process performed based on the operation of the numeric keypad 19 is continuously permitted (steps S47 to S50).

  Since the value 1 is already set in the selection completion flag F at the present time, the determination result in step S50 is constantly true.

  As described above, the administrator can browse and rewrite all of the user authentication information storage file shown in FIG. 5, but the user can view only the user authentication information of the user, The rewriting is permitted only in the portion of the user password in the user authentication information.

  In this way, even if the user rewrites the user authentication information, the key number of the user authentication information remains as it is, so that the administrator can easily identify the user who issued the key by the administrator and use the user authentication information. You can check the change history. Therefore, even when the user rewrites the user authentication information, if the disqualification matters arise for this user, the administrator must restrict the user's operation to release the door lock device. Can do.

  Regarding the rewriting of the user authentication information, specifically, on the assumption that each user manages each user authentication information, the initial value of the user authentication information issued by the administrator is a result of the change. Overwrite the user authentication information and update the user authentication information without leaving the previous change history (in this case, the user authentication information input via the numeric keypad 19 after the change or transmitted from the mobile phone 2) The user authentication information is always compared with the user authentication information stored at all addresses), or on the assumption that each user manages each user authentication information. The authentication information is stored in the next empty address in order, and only the user authentication information stored in the latest address of each user is valid user authentication information. The user authentication information of each user before that is left in the user authentication information storage file as a change history (in this case, the user authentication information input via the numeric keypad 19 after the change or transmitted from the mobile phone 2) The user authentication information is always compared with the user authentication information stored at the latest address of each user).

  Finally, when the user operates the END key in the numeric keypad 19 to declare the completion of the input process, the CPU 13 detects this operation in the determination process in step S48, and the contents of the user authentication information storage file on the RAM 15 are detected. Is overwritten and stored in the user authentication information storage file in the nonvolatile memory 16 to update the contents of the user authentication information storage file in FIG. 5 (step S52), and an end message is displayed on the display 20 to complete the selection. The value of the flag F is initialized to 0 (steps S53 and S51), the display of the end message is cleared (step S8), and the initial standby state is restored. As described above, writing in the “contact” and “other optional information” fields corresponding to the menu number “022” is optional.

  In this way, each time the user updates his / her user authentication information, the user himself / herself operates the keyboard of the mobile phone 2, and changes the value of the user authentication information as the change result of the mobile phone 2. Store in non-volatile memory.

  Therefore, even if the mobile phone 2 owned by the user is lost due to some trouble, the user can directly operate the numeric keypad 19 of the door lock device 4 without using the mobile phone 2. Authentication information can be easily rewritten to another user authentication information. In this way, by forcing the user authentication information currently stored in the door lock device 4 and the user authentication information currently stored in the mobile phone 2 to be in a mismatched state, Even when the lost mobile phone 2 is handed over, it is possible to prevent a door lock release operation by a third party who has stolen the mobile phone 2 in advance.

  In addition, when the initial setting value set by the administrator is used as the user authentication information as it is, or when the individual user is the administrator, the manufacturer, dealer, etc. set the initial setting value at the time of shipment of the door lock device 4. When the user is notified by e-mail or mailing a document, the user authentication information, which is an initial setting value, is operated by operating the keyboard of the mobile phone 2 when the user acquires the user authentication information. Is stored in the nonvolatile memory of the mobile phone 2.

  Thus, when the user authentication information is stored in the nonvolatile memory of the mobile phone 2 owned by the user, the unlocking operation of the door 3 using the mobile phone 2 is allowed for the first time. .

  When performing the unlocking operation of the door 3 using the mobile phone 2, the user first operates the collation start switch 18a of the door lock device 4 to start the data transfer by infrared communication to the door lock device 4 (CPU 13). ).

  The CPU 13 detects the operation of the collation start switch 18a in the determination process of step S3 described above, restarts the timer T that measures the allowable operation time, and starts measuring the elapsed time after the operation of the collation start switch (step S56). ), The infrared receiver 21 is activated (step S57), and the user authentication information read from the non-volatile memory of the mobile phone 2 is awaited to be transferred as data up to the time-up of the timer T. (Step S58 to Step S59).

  As described above, the user authentication information is transferred from the mobile phone 2 to the door lock device 4 by, for example, storing the user authentication information as a notepad file in the nonvolatile memory of the mobile phone 2. It can be realized very easily by performing transmission processing by the infrared communication device of the mobile phone 2 with this file as a transmission target, and there is no need to modify the program or circuit of the mobile phone 2.

  During this time, when the user authentication information is transferred from the infrared communication device of the mobile phone 2 by an operation on the user side, the CPU 13 functioning as the lock release determination unit 8 sets the infrared reception device 21 functioning as the reception unit 6. The user authentication information is received and temporarily stored (step S60), and the user authentication information storage file of FIG. 5 is searched (step S61). The received user authentication information is shown in FIG. It is determined whether it is stored in the user authentication information storage file (step S62).

  At this time, as described above, the initial value of the user authentication information issued by the administrator is overwritten with the user authentication information as a result of the change, and the user authentication information is authenticated without leaving the previous change history. In the case where the information storage file is updated and stored, the received user authentication information is compared with the user authentication information stored in all addresses of the user authentication information storage file of FIG. In the case of storing the user authentication information as the change result in the next empty address in order and using only the user authentication information stored in the latest address of each user as valid user authentication information, The received user authentication information is valid user authentication information in the user authentication information storage file of FIG. 5 (users stored at the latest address of each user). Is compared with the authentication information) only.

  Here, when the received user authentication information is detected from the user authentication information storage file of FIG. 5, the CPU 13 functioning as the unlock determination means 8 further configures a part of this user authentication information. The administrator authentication information storage file in FIG. 4 is searched based on the value of the key number to be obtained, the expiration date stored corresponding to the key number is obtained, and the year, month, day, hour, minute and second are referred to the internal clock Is determined to determine whether or not the key number is currently valid (step S63).

  If the determination result in step S63 is true, that is, if it is determined that the user authentication information transmitted from the mobile phone 2 is appropriate and the key number is valid. As a result, the CPU 13 functioning as the lock release determination means 8 drives the electric lock 22 functioning as the lock mechanism 5 via the input / output circuit 17 and the driver 23 to switch the state from the locked state to the unlocked state. The user is allowed to open the door 3 (step S64), the infrared receiver 21 is returned to the non-operating state again (step S65), the display 20 is set to the non-displaying state (step S8), and the initial state is again displayed. Return to standby state.

  When the change history is left in the administrator authentication information storage file, the user authentication information set by the user corresponding to the key number included in the administrator authentication information of the previous generation, that is, one generation Only the user authentication information generated by the user by setting the user PIN for the previous key number and the initial setting value or key number of the user authentication information newly set for the user by the administrator The user authentication information that has been rewritten may be valid due to the expiration date. Therefore, when the administrator who has newly changed the user authentication information and key number of the user is delayed, the user himself / herself does not know the initial setting value of the new user authentication information and the contents of the key number. If the administrator authentication information of the previous generation is within the expiration date, the user uses the user authentication information currently stored in the mobile phone 2 to lock the door 3 with the electric lock 22. Can be released.

  If the determination result in step S62 or step S63 is false, that is, the user authentication information is inappropriate, or the user expiration date is valid even if the user authentication information itself is appropriate. When it is determined that the lock has expired, the CPU 13 functioning as the lock release determination means 8 skips the process of step S64 related to the lock release and displays an error message indicating a failure in collating the user authentication information. (Step S67) After returning the infrared receiver 21 to the non-operating state again in the same manner as described above (Step S65), the error message on the display 20 is cleared (Step S8), and the initial standby state is resumed. Return.

  In this case, there is a possibility that the determination does not match because the user authentication information transferred from the user's mobile phone 2 is inappropriate, and there is a possibility that the check fails due to a problem such as disturbance and the determination does not match. In the latter case, the door lock by the electric lock 22 can be released by operating the collation start switch 18a again and transmitting the user authentication information from the mobile phone 2 to the door lock device 4 again. If the transmitted user authentication information is inappropriate or the expiration date has expired and the use of the key number has become invalid, the door lock cannot be released even if this mobile phone 2 is used. .

  If the determination result in step S59 is true, that is, if transmission of user authentication information from the mobile phone 2 is not detected even after a predetermined time has elapsed since the operation of the collation start switch 18a. The CPU 53 displays an error message indicating that there is no transfer of the user authentication information itself and an error message indicating failure of collation (steps S66 and S67), and then performs the infrared receiver 21 in the same manner as described above. The state is returned to the inoperative state again (step S65), the error message on the display 20 is cleared (step S8), and the initial standby state is restored again.

  In this case, there is a possibility that the transmission data may not be received due to a problem with the infrared transmission state or reception state. In such a case, for example, the mobile phone 2 may be operated one step closer to the door lock device 4. In some cases, the door lock by the electric lock 22 can be released.

  As described above, in this embodiment, access to the Web page and manual input operation of user authentication information are not required when the door lock is released, so the door lock release operation is extremely simple and requires an Internet connection. Since the use of servers and servers is unnecessary, the scale of the system is small and maintenance costs are not required, and the problem of redundancy in waiting time due to deterioration in communication conditions is solved. Furthermore, since the basic functions of a general mobile phone equipped with an infrared communication device are used, there is no need to mount a special program or circuit on the mobile phone 2, and the mobile phone 2 that replaces the key is temporarily lost. Even in such a case, since the user password of the user authentication information can be rewritten by the user's own hand using the user authentication information that is valid at that time, the lost mobile phone 2 It is possible to prevent a door lock release operation due to theft.

  In this embodiment, the case of using a mobile phone as a mobile terminal has been described. However, a PDA or other device can be used as a mobile terminal, and as a short-range communication wireless communication means, IrDA standard infrared communication In addition to the device, it is possible to use various short-distance communication wireless communication means capable of transmitting and receiving information to and from the door lock device 4 without requiring connection to a network such as the Internet.

  In addition, only the personal identification number of the user authentication information is allowed to be rewritten by the user, and the key number remains unchanged even if the user rewrites the user authentication information. The change history of the user authentication information can be identified and confirmed. Therefore, even if the user has rewritten the user authentication information, if the user is disqualified, the key number or its expiration date is invalidated, and the user can lock the door. The release operation of the device 4 can be reliably restricted.

  The door lock device 4 can be freely used for building doors, gates, safes, automobile doors, and other opening / closing members that require opening / closing and locking operations. .

  Further, the door lock device 4 is provided with a network interface, and the administrator authentication information is set and rewritten and the initial setting value of the user authentication information is set from a remote administrator terminal via the network. The door lock device 4 may be set. The problem of redundancy of waiting time due to the deterioration of communication status is a problem when the user opens and closes the door 3, so that the processing related to the work on the administrator side can be performed even via the network. No negative effects will occur. In that case, the initial setting value of the user authentication information, the expiration date of the key, etc. are automatically used from the administrator terminal connected to the door lock device 4 via the network to the user's mobile phone 2 using e-mail or the like. It is also possible to transmit. Even when such a configuration is applied, the password of the user authentication information can be rewritten immediately by a user's manual operation on the numeric keypad 19 constituting the authentication data input means on the door lock device 4 side. Problems such as the loss of the mobile phone 2 can be dealt with immediately.

  As the user authentication information, a combination of a key number and a user password is used. However, when the user himself / herself changes the user password, data such as photographs and images is not limited to numbers and characters. It may be used as a user password. In that case, since it is practically impossible to input data such as a photograph or an image using the numeric keypad 19, the cellular phone 2 is used by utilizing the infrared communication function of the cellular phone 2 and the infrared receiver 21 of the door lock device 4. It is assumed that binary data such as photographs and images stored in the non-volatile memory is directly read into the door lock device 4.
