Description

  The present invention relates to a door lock operation method and a door lock system, and more particularly, to a door lock operation method and a door lock system that enable a door lock to be electrically locked / unlocked using a preset password.

  Housing, offices, warehouses and other buildings (facility) or specific rooms or areas in the building shall be provided with doors with door locks, and identification permitted for the protection (security) of people, goods, information, etc. It is common practice to limit the free access of third parties other than people.

  For this purpose, it is common to lock / unlock by inserting a key into a keyhole of a lock provided on the door. However, such a mechanical door lock may be illegally operated due to picking or the like, which is a serious social problem. Therefore, various electric or electronic door lock systems such as a PIN code system, IC card system, and fingerprint verification system have been developed and put to practical use as a highly secure door lock system by eliminating the anxiety such as picking by eliminating the keyhole. Has been.

  However, if the personal identification number cannot be freely changed in the personal identification number type door lock system, there is a possibility that the function will be transmitted at all if the personal identification number is known to a third party. In addition, the IC card type door lock system may cause the IC card to be lost or misplaced due to self-carelessness or theft, as in the case of the conventional key method, even if there is no fear of picking. Even the person cannot be unlocked, and for example, a situation may occur in which the person cannot enter the house.

  Furthermore, the door lock of the fingerprint collation system is considered to be a system with high security because there is no risk of misplacement or loss unlike the IC card system described above, and it cannot be unlocked (unlocked) by anyone other than the registrant. However, there is a disadvantage that only the administrator registered in advance can unlock.

  A specific example of such a defect will be described. For example, if a very close acquaintance visits a house with such a door lock while absent, it cannot be entered even if the door lock is unlocked and the user wants to enter the house. In addition, when the acquaintance is the first visit, it is impossible to register the fingerprint in advance. For example, if a parent in the country suddenly visits in the absence of the person, even if he / she promises the arrival time in advance, the visitor arrives earlier than the promised time while he / she goes out for shopping etc. If you have a close friend who lives in a remote location, and you have accidentally contacted your mobile phone when you are away from home due to a business trip, etc. A situation arises in which a visitor wants to be invited to the home. However, the conventional door lock system cannot cope with such a situation quickly and effectively.

  In addition, the prior art relevant to the door lock system mentioned above is disclosed by some technical literature. An electric lock device capable of assigning unlock permission times to a plurality of encryption numbers has been disclosed (see, for example, Patent Document 1). Further, a vehicle lock operation system is disclosed that incorporates a database for storing registration information and a password in association with each other, and allows the vehicle owner to safely and easily allow others to unlock the vehicle door (for example, , See Patent Document 2). Furthermore, a key management method is disclosed in which a code number or person identification information is sent to a building to be unlocked via a communication line together with date and time information, thereby eliminating the need for movement for delivery of keys and movement for return ( For example, see Patent Document 3.)

Registered Utility Model No. 3041729 (page 5-6, Fig. 1) JP 2004-339737 A (page 6, FIG. 1) Japanese Patent Laid-Open No. 10-54166 (page 4, FIG. 1)

The present invention has been made in view of the above-mentioned problems of the prior art, and confirms that the setting, change, and setting of the temporary security code for temporarily unlocking the door lock have been changed from the communication means of the administrator. It is an object of the present invention to provide a door lock operating method and a door lock system that can notify a visitor 's communication means designated by an administrator of the temporary password.

  The door lock operating method and door lock system of the present invention employ the following characteristic configuration.

An operation method of a door lock system according to the present invention is an operation of a door lock system having a door lock that is electrically locked by inputting a personal identification number and a server connected to the door lock via the Internet. Is the method. The server receives a number transmitted from the administrator 's communication means via the Internet , sets the number as a temporary security code for temporarily unlocking the door lock, and sets the number to the administrator via the Internet. The temporary security code is notified to the communication means of the visitor designated by. The server notifies the administrator 's communication means that the temporary security code is set to the door lock. The door lock is unlocked when the temporary password is set by the visitor after the temporary password is set. The door lock notifies the server that the door is unlocked via the Internet . Then, the server notifies the manager 's communication means that the server has been unlocked. Further, the door lock automatically deletes the temporary security code when the predetermined expiration date of the temporary security code expires, and notifies the server that the temporary security code has been deleted. The server notifies the manager 's communication means of erasure of the temporary password transmitted from the door lock via the Internet . According to the present invention, it is possible to confirm from the administrator 's communication means that the temporary security code for temporarily unlocking the door lock is set, changed, and that the setting has been changed, and the temporary security code can be confirmed by the administrator. It is possible to notify the designated visitor 's communication means.

In the operation method and door lock system of the door lock system of the present invention, it can be confirmed from the administrator 's communication means that the setting, change and setting of the temporary security code for temporarily unlocking the door lock have been changed. It is possible to provide a method of operating a door lock system and a door lock system that can more easily manage a temporary security code. Furthermore, in the door lock system operating method and door lock system according to the present invention, the door lock is solved by referring to the temporary security code or the security code notified from the server , the number input from the outside, and the time. Since a relatively simple process such as locking and erasing the temporary security code with time is performed, the door lock can be manufactured at a lower cost.

  Hereinafter, the configuration and operation of a preferred embodiment of a door lock operating method and a door lock system according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing the configuration of a preferred embodiment of a door lock system according to the present invention. The door lock system 10 includes an antenna 11, a transmission / reception unit 12, a CPU (central processing unit) 13 as a control unit, a ROM (read only memory) 14, a password memory 15, a clock 16, a key lock unit 17, and a password input. The unit 18 is configured.

  Here, to the CPU 13 of the door lock system 10, a transmission / reception unit 12, a ROM 14, a personal identification number memory 15, a clock 16 and a key lock unit 17 are connected. An antenna 11 is connected to the transmission / reception unit 12.

  The door lock system 10 is divided or separated into the inside of the door (for example, indoors) and the outside of the door (for example, outdoors), as indicated by dotted lines in FIG. Then, in order for the operator entering the inside of the door to input the personal identification number set by himself / herself, the encryption number input section 18 is attached to an appropriate fixing member outside the door.

  As described above, the CPU 13 is mounted on the inside (outdoors) of the door of the door lock system 10, and the CPU 13 is electrically connected to the respective units 12 to 18 constituting the door lock system 10. Of these, the ROM 14 is a read-only memory that stores various control programs to be executed by the CPU 13. The key lock portion 17 is a mechanical portion (mechanism) that securely locks the door, that is, prevents a third party other than the authorized person from entering the door unless the door is normally unlocked.

  The clock 16 represents the current time, that is, year, month, day, hour, minute, and second. The personal identification number memory 15 is a non-volatile memory, and stores a personal identification number preset and registered with the authorized person. When the password is input from the password input unit 18 by the operator, the input password and the password stored in the password memory 15 are compared by the CPU 13. If both numbers match, the key lock unit 17 unlocks the door, the door can be opened, and the door can enter the interior.

  On the other hand, the transmission / reception unit 12 can be connected to, for example, a mobile phone network. When the transmission / reception unit 12 receives the change of the personal identification number via the antenna 11, the contents can be stored in the personal identification number memory 15, and the personal identification number can be changed by using a communication means such as a mobile phone from the outside. , Making additions possible.

  Next, the operation of the preferred embodiment of the door lock system 10 of the present invention shown in FIG. 1 will be described with reference to FIGS. FIG. 2 is an explanatory diagram showing a specific example of the password memory 15 shown in FIG. FIG. 3 is a specific example of a password setting screen. FIG. 4 is a specific example of an email transmitted to a visitor. FIG. 5 is a specific example of mail transmitted from the door lock system to the person who is the door lock manager.

  First, a specific example of the contents (data) stored in the personal identification number memory 15 which is a component of the door lock system 10 of FIG. 1 will be described with reference to FIG. As shown in FIG. 2, the code number memory 15 stores a pair of conditions 15b and code numbers 15c corresponding to a plurality of memory numbers 15a. In the specific example shown in FIG. 2, the condition is “normal” in the memory number 1, which is the personal identification number (normal personal identification number) that is normally used by the person (for example, a resident) for the operation of the door lock. Number). Since the personal identification number is “1234”, when the personal identification number “1234” is input from the personal identification number input unit 18 of FIG. 1, the key lock unit 17 is unlocked (or released) and the door can be opened. it can.

  In this specific example, the personal identification number is a four-digit number, but it is not necessarily limited to a four-digit number, and it is a matter of course that a symbol other than a number may be included. Further, when the number of normal users is one, such as an apartment where one person lives, it is sufficient to set one normal password for memory number 1, for example, as shown in FIG. When there are a plurality of residents, an individual normal personal identification number is set and given to each resident.

  Next, with reference to FIGS. 2 and 3, a method for setting a personal identification number in the door lock system of the present invention will be described. FIG. 3 shows a temporary (or temporary) personal identification number when the person accesses a server (not shown) of the door lock system 10 from the outside through a communication means such as a mobile phone or a PC (personal computer). A specific example of a password setting screen for setting is shown.

  First, the person who sets the temporary security code inputs his / her ID and password. Then, a period (or time) to be set is input. In the specific example shown in FIG. 3, the date “January 1, 2006” and the time “11:00 (11:00 am) to 17:00 (5 pm)” are set in the memory number 2. If it is desired to set the “normal” state, which means that it is used every day, this field may be set to “normal”. In this specific example, since the temporary security code is set to “5678”, when this security code is input from the security code input unit 18 shown in FIG. 1, the door lock unit 17 is locked only during the specified period. Indicates that it can be unlocked.

  In addition, one or more addresses of persons who want to receive transmissions are input as transmission destination mail addresses. In this specific example, “yamada@taro.ne.jp” (for example, the person himself) and “yamada@hanako.ne.jp” (for example, the key lock portion 17 of the door lock is unlocked as a transmission destination, and entry is desired. By inputting the e-mail address of an acquaintance, an e-mail having the contents shown in FIG. 4 is transmitted to the person and the acquaintance (visitor). That is, the destination is “yamada@hanako.ne.jp”, the setting period is 11:00 to 17:00 on January 1, 2006, and the temporary security code is “5678”.

  By receiving this e-mail, it is possible for the “person” who is the setter to confirm that the temporary security code has been successfully added (if there is an error in the settings, change the settings). Can be corrected). Further, the “acquaintance” who is the set person can confirm the “unlockable time” and “password” of the key lock portion 17 of the door lock by receiving this mail. If necessary, a simple message or the like can be added to the text.

  The additional data of the personal identification number is also transmitted to the door lock system 10 in FIG. 1, and the condition “11:00 to 17:00 on January 1, 2006” and the temporary personal identification number “5678” are added to the memory number 2 in FIG. Is stored in the password memory 15. During the set period, both the password numbers “1234” and “5678” can be used to unlock the key lock unit 17 of the door lock system 10.

  As mentioned above, when the “person” is absent, for example, when there is a notification from the “acquaintance” that he / she visits unexpectedly, and he / she wants to wait at home, this fact is notified to the “acquaintance” by e-mail. Thus, it is possible to add a “temporary password” that allows the key lock unit 17 to be unlocked temporarily in the password memory 15. When this “acquaintance” arrives and the temporary password “5678” is input from the password number input section 18 within a predetermined period, the key lock section 17 is unlocked and can enter the room or the room. Become. Here, the principal does not need to notify any other person including the “acquaintance” of his / her normal personal identification number stored in the memory number 1 of the personal identification number memory 15 which is always in use. It should be noted that the “temporary password” notified to the “acquaintance” is valid only for the set period of time and is automatically deleted and invalidated thereafter, so that security can be ensured.

  Next, FIG. 5 is a specific example of a mail notifying that the door lock (the key lock unit 17) has been unlocked. When the temporary password “5678” is input from the password input unit 18 by some person, the date and time information at that time (in the example shown, 13:32 on January 1, 2006) is read from the clock 16. It is. Then, at 13:32, an e-mail indicating that the door lock is unlocked with the temporary security code “5678” is sent via the mobile phone network via the transmission / reception unit 12 and the antenna 11, for example. Thereby, the “person” can confirm that the “acquaintance” has arrived at the house at this time and has unlocked the door lock.

  The contents of the memory number 2 in the password memory 15 shown in FIG. 2, that is, the temporary password, is passed from the password memory 15 by the CPU 13 after 17:00 (5 pm) on January 1, 2006. It is automatically deleted. Therefore, after that time, the temporary security code becomes unusable, and even if the “acquaintance” or another person inputs the temporary security code “5678” from the security code input unit 18, the door lock can be unlocked. It becomes impossible.

  As described above in detail, according to the door lock operating method and the door lock system of the present invention, the “person” who is an administrator can use the personal identification number of the door lock system 10 at home from the outside by communication means such as a mobile phone. Can be set freely, and even if there are unexpected visitors, by adding a temporary security code for a limited time without notifying your normal security code, you are allowed even in the absence of the person Can be invited to your home. Also, it is possible to freely change or add to the user's normal personal identification number by using a communication means such as a mobile phone from the outside.

  The transmission / reception unit 12 of the door lock system 10 of FIG. 1 has been described as a transmission / reception unit of a mobile phone that can be connected to a mobile phone network. However, the present invention is not limited to a mobile phone but may be a PHS (Personal Handy-phone System) or the like. However, since both mobile phones and PHS are charged, the use of a wireless LAN can be considered. If there is a contracted Internet connection in a home PC, a wireless LAN that does not incur additional charges can be used. Further, as a wired rather than wireless connection, a LAN cable may be used to connect to the Internet.

Then, the contractor uses his / her mobile phone 25 to input the change / addition information of the door lock system on the screen of FIG. 3 described above (step S2). The items to be input here are a contractor ID, a password, conditions such as a set time, a personal identification number, and a destination mail address for transmitting the set contents as described above.

  Next, the service center 24 confirms, that is, authenticates whether the ID and password match the registered content (step S3). If this authentication matches, the setting of the corresponding door lock system is changed (step S4). The communication method between the service center 24 and the door lock system 27 communicates with the door lock system 27 from the service center 24 of FIG. Communication may be performed from the service center 24 via the Internet 21 by ADSL (Asymmetric Digital Subscriber Line) or FTTH (Fiber-to-the Home). Whether to communicate by the soil method depends on the contract contents between the contractor of the home door lock system 20 and the service center 24.

  Next, when the door lock system 27 changes the personal identification number memory (see the personal identification number memory 15 in FIG. 1) according to a setting change instruction from the service center 24, a notification of completion of setting is notified to the service center 24 (step S5). . Upon receiving this setting completion notification, the service center 24 transmits a mail as shown in FIG. 4 to the mobile phone 25 of the contractor and the mobile phone 26 of the visitor, which are the destinations specified in FIG. Step S6).

  The visitor who has received and confirmed the mail as shown in FIG. 4 inputs the personal identification number (for example, “5678”) from the personal identification number input section of the door lock system 27 (see the personal identification number input section 18 in FIG. 1). The lock (key lock unit 17 in FIG. 1) can be unlocked under a predetermined condition (within a set time).

  Next, the operation after the door lock is unlocked will be described based on the lower part of the sequence diagram of FIG. When the door lock is unlocked, an unlock notification is sent from the door lock system 27 to the service center 24 (step S7). Therefore, the service center 24 transmits an unlock notification including the unlock information as shown in FIG. 5 to the contractor's mobile phone 25 (step S8). The unlock information transmitted to the contractor's mobile phone 25 by this unlock notification is, for example, the date and time of unlocking and the password used for unlocking. By this mail, the contractor can confirm the arrival of the visitor at the home.

  Here, as for the visitor's personal identification number, as shown in FIG. 2, for example, an expiration date of 17:00 on January 1, 2006 is set in the memory number 2 of the reef number memory 15. When this expiration date arrives, the contents of the memory number 2 in the password memory 15 are automatically deleted under the control of the CPU 13. Therefore, the personal identification number “5678” after the expiration date becomes unusable. Therefore, a change in the memory contents of the personal identification number memory (that is, deletion of the memory number contents) is transmitted from the door lock system 27 to the service center 24 (step S9). Next, the service center 24 notifies the contractor's mobile phone 25 of this memory content change (step S10).
