[For public use message ]

Although not described in the present invention, basic functions of existing door locks (e.g., automatic locking after door closing, etc.) may be included. The door lock for the present invention additionally has a display device (e.g., a liquid crystal display), and outputs a message (a public PR message or a private message provided to an authorized user) input by the user to the display device. A " message " includes " text message (visual message) " and " voice message (auditory message) ".

In the case of digital door locks, most of them usually have a method of authenticating by a password (password). This is because it is cheaper than the biometrics method and it is advantageous not to carry a key. In the case of the password system, since a numeric keypad is usually provided, it can be used as a keypad for inputting characters. The door lock according to the present invention may be constructed not only by a password method, but also by a biometric method such as an RF card method and a fingerprint.

FIG. 1A is a conceptual block diagram in the case where a message input / output function is additionally provided in a door lock having a numeric keypad, and FIG. 1B is a configuration diagram in this case. In FIG. 1B, the Korean character keypad for the Korean character input technique presented by the applicant is presented, but it is obvious that any character input technique can be applied. In FIG. 1b, a case in which "PR message for public use" is simply displayed is shown. It is within the doorlock to generate a message based on the input value. In Fig. 1a, " sound output unit " outputs a warning sound or guidance sound, and may or may not be provided depending on the product. Although the "password input unit 13" and the "message input unit 14" may be formed on the same keypad, when implemented in a software manner, the message input mode and the password input mode will be different. It is expressed that there are branch input units 13 and 14.

In addition, the size of the display device (e.g., liquid crystal) may be too small to display the message. To solve this problem, it is possible to display the message while sliding. For example, if only one line is to be displayed, the message will slide from right to left. Even if several lines are displayed, it is possible to display the entire message while sliding downwards from below.

In the past, when the general house was generalized, there was a "nameplate", and it can be expected that the door-lock release message of the present invention can provide softness in a hard time when only the number (apartment lake) . Even if a home or company does not have a clear message, it can be said that "This is a security company ㅇ ㅇ security area!"

[Private use message ]

Sometimes it is not just a public message that is open to everyone. For example, "My dear son, I am late today. You can not have a message like "Dinner ready to be taken care of ..." so that everyone can see it for public use. This is because the thief is advertising the empty house. This should only be visible to a specific authorized user. Therefore, it should be stored as a "private message" and only the authorized user should be able to view the message.

A typical method for browsing a message is to input a user ID and a password corresponding to the user ID to browse the message. However, recently, a door lock system has been introduced in which a plurality of passwords are designated and each user uses his / her own password. In this case, since the specific password itself serves as an ID for a specific person, when a specific password is input, a specific message designated to the user can be output.

There are various ways to store private messages, but here is an example. The user can enter the administrator mode with his / her password, select a user to send a message among the list of users, and store the private message by a procedure of creating a desired message after user selection. Likewise, the process of outputting a private message is possible by a procedure in which a user to whom a message is to be transmitted is input (a corresponding password is input), and a process of outputting the message.

For example, for a password (password) "1111" or "b a" used by a son, save the private message ("Beloved Son, today is late, (&Quot; 1111 " or " a "), the message is output in a promised manner (output to the display window of the door lock, text To output a voice or output a stored voice). Preferably, after the message is output, if the user takes some action (for example, press the "OK" button or the "delete" button), the door lock is opened or the entire message is output Door locks can also be opened.

Quot; [1] button = [a] button " in the keypad illustrated in Fig. 1A, and the scan code (unique key value defined in each key) is the same. Therefore, whether or not the user is conscious of "1111" or "b a", the password is expressed as "1111" or "b a" since the door lock recognizes the same. This is the same as entering a Korean [K] key or entering the English [a] key when entering a password on a PC. [1] - [0] Since the number buttons are the same in all products, the following shows mainly numeric values as passwords.

[External Interface Module]

The present invention is not limited to a password-type door lock. In the case of a door lock that does not have a keypad as an input device, the interface module 23 (23) is connected to a separate built-in input device or an external input device ). Also, even if the door lock includes the input device 23, it is possible to input a desired message through an external input device (e.g., a mobile phone, a PC) desired by the user.

FIG. 2A is a block diagram when the external input device is connected. When an external input device is used without using an internal input device (e.g., door lock keypad) provided in the door lock itself, only the scan code value (unique key value defined in each key) necessary for character generation in the external input device You can generate a message from the doorlock, hand it over to the external input device, and display the message. The former is a case in which a message is generated for an input value in a door lock as shown in FIG. 1B, and the latter is a message generated in an external input device and a message is generated in a door lock.

The interface 26 with the external input and output device 27 may be through any means including infrared communication, Bluetooth, WiFi, WiBro, wired Internet, (Eg, CDMA, GSM) and a short text messaging function. 2B is a configuration diagram when an external input / output device 27 is applied to a similar terminal having a communication function of a cellular phone or a cellular phone. In Figure 2b, the company posted public PR messages.

(Eg, CDMA or GSM), it is advantageous to control the door lock at a remote place (eg, register a message) when it is not a short-range wireless communication means such as infrared communication or Bluetooth. In this case, the control program that operates on the mobile phone in conjunction with the door lock will be realistically implemented as a program on the wireless Internet platform of the mobile phone.

[Notify Promised User]

In addition, a wired or wireless communication module 38 may be provided in the door lock. See FIG. For wired communication, ordinary telephone and wireless communication are representative of communication function of mobile phone. The difference between the wired or wireless interface module 27, 37 and the wired or wireless communication module 38 is as follows. The interface modules 27 and 37 are modules that enable control of the door lock through the external input / output device, and the communication module 38 may be regarded as means for communicating with external devices. In FIG. 3, the wired and / or wireless interface module 37 may be provided as in FIG. 2a or may not be provided as in FIG. 1a. If 37 as a mobile communication is provided, 38 as a practical mobile communication will be constructed together with (37), but conceptually shown separately. Likewise, if (37) is provided as a wired communication (e.g., the Internet), it will be practically configured with (38) as wired communication.

When a door lock is opened with the first output of a private message, a message (a text message or a voice message) is transmitted to the mobile phone of the promised user (for example, the user who has input the private message or the entire administrator) It is possible. For example, "Prompt the promised user that he printed the message to his son (" 1111 "password user) at xx xx xx xx xx xx in 2006. If, in all cases, a text message is sent at the entrance of a particular user (the son using the password "1111" or "b") in the case, if the son opens and closes 10 doors within 10 minutes, Message transmission, which is a huge waste of operating costs, and even a user receiving a message is very annoyed by spamming messages.

In the case of a private message, when a plurality of designated users are specified, when each user first reads the message (that is, the door lock outputs the first message for a specific user), the message is notified to the manager's mobile phone .

That is, in addition to the above-described procedure, a procedure for confirming whether the private message is first output to the user to be browsed and a procedure for notifying the promised user of the fact that the private message has been output for the first time In addition,

If the mobile phone number of the user who is the subject of the private message is registered in the user database (stored in the memory 32 of the door lock) in the door lock to which the external communication function 38 is added to the door lock, It is also possible to send the message to the mobile phone.

Further, even when there is no private message, only when a specific user opens the door lock for the first time in a specific time zone (eg, 0:00 to 24:00, 13:00 to 24:00 or 06:00 to 12:00), only the promised user It is possible to give a notification (a text message or a voice message) to the manager. An example of a family has the effect of letting the mother go out and know when she is home.

[User Management]

The management of the user can be performed similar to the existing user management (user management in a device such as a PC). A simple example related to the present invention is as follows. In this example, it is assumed that a specific user is not recognized by an ID and a password, and that the password itself has a specific user authentication function.

First, it is assumed that the user of the password registered by default has the highest manager function. The super administrator can create multiple passwords (ie, users) and grant privileges (eg, administrator privileges or general user privileges). Each user can enter his / her password, enter the management mode to change his password, or input a public or private message.

Here, it is an operational policy issue that the user designated by the super administrator as the super administrator has the same privilege as the super administrator (eg, generation of password, creation of the user, etc.). Also, whether to allow users to subdivide the level of the user or create a public message with the normal user privilege is also a problem in the operational policy and is not mentioned anymore.

First, when the super administrator enters the super administrator password and enters the management mode to inquire the registered user list, the following contents stored in the memory of the door lock will be displayed. Of course, the process of entering the management mode may be performed by the input device of the door lock itself, or may be performed in conjunction with an external input device (e.g., a mobile phone or a PC).

password User name authority (cellphone) 7777 or similar Super administrator

When a user is created, a user is added according to a predetermined procedure (eg, a menu button is clicked and a password is selected from a menu to be created). The following is an example of modifying super administrator information and adding users. The user name can be registered as an alias to easily identify the user of the specific password, and the user's name or position can be registered. Realistically, the super administrator will be the security officer of the organization (company or home) or the person in charge of the security guard company.

password User name authority (cellphone) 7777 or similar Security Officer Super administrator (010-7777-7777) 5555 or CEO manager (010-5555-5555) 3333 or c Temple Normal

In a door lock not equipped with a display device (e.g., a liquid crystal display) and an input device, it is impossible to implement such a user-friendly interface (e.g., inputting and displaying a user name). However, if a liquid crystal is provided as in the present invention, Interface configuration is possible. When performed by an external input / output device, the output of the management details will also be displayed on the display device of the external input device (eg, the screen of the PC or the liquid crystal of the mobile phone), not the liquid crystal of the door lock. Of course, once the management details (eg creation of a public message) are completed, the message for disclosure is displayed on the display device of the door lock, but the details of the management state should not be displayed on the display device of the door lock of the user and the remote location. Further, the contact number of the mobile phone or the like is indicated in parentheses because it is not necessary when the communication module 38 is not attached to the door lock itself.

When you create a public message (for example, press the menu button and select Create PR message for public), you will enter the message for creating a public message, save the message, and save it. If you want to modify a specific user's information, you can select a specific user and go to "Modify Information" to modify the information. Likewise, when creating a private message, select the user (s) to be targeted (eg, select one or more check boxes) and then enter the "Create Private Message" menu (eg press the menu button and select Create Private Message) You can do it.

What is important here is that if a general user (eg son) using the password "1111" or "b" is entering the administration mode, the password of the other person should not be visible in the user list. That is, the user (password) list is preferably displayed as in the following example. Whether or not the mobile phone number can not be viewed with the normal user privilege is also a problem in the operational policy.

password User name authority (cellphone) **** Security Officer Super administrator (010-7777-7777) **** CEO manager (010-5555-5555) 3333 or c Temple Normal

In the case of a small company, it may be used to manage the attendance of the employee by using the door lock open log data. Of course, this can be achieved by connecting a device such as a PC through an external interface module of the door lock and dumping the door lock open log data.

In the example, the password is expressed as four digits for convenience, but security can be enhanced by designating the minimum number of password digits according to the security policy.

[Emergency Contact]

When a door-to-door communication function is added to the communication module 38, an unauthorized visitor (i.e., a visitor who has not been given a password) makes an emergency call (telephone call) to the promised user can do. Of course, in this case, the mobile communication number assigned to the door lock and the telephone number of the promised user (e.g., the super administrator) are not exposed. This means, for example, that the courier can cope with the absence of a person without having to inform the courier in advance of the mobile phone number of the baggage claimer. In addition, the emergency phone number can be registered in the phone number of the security company.

[Notification of security anomaly]

When a communication module 38 is added to the door lock, when an alarm occurs (eg, a password inconsistency more than a certain number of times (eg, three times)), an appointed user (such as a super administrator or a security guard company) A notice (text or voice) service is available.

The procedure may include a procedure for counting password discrepancies, a procedure for checking occurrence of discrepancies over a predetermined number of times, and a procedure for notifying the fact of the fact by means promised to the promised contact.

[Dual Security, Secondary Password]

When the wired or wireless communication module 38 is added to the door lock, double security is possible by inputting the secondary password to the user. If the password of the "president" (in this case, the primary password) "5555" is exposed in the case, a user who should not be authorized can open the door lock. However, according to the security policy (eg, the super administrator sets the second password), enter "5555", enter the second password (eg, A random number generated by a password or a door lock) is transmitted as a text message, and the door lock is opened by re-entering the secondary password within a predetermined time (e.g., 30 seconds).

When the secondary password is applied, the input of the primary password serves to identify (not to approve) the user. Such user identification can not be made only by inputting the primary password, ), RF card recognition, and the like. Then, a second password can be sent to the mobile phone registered to the user and requested to input, thereby completing the double security. If the RF card is used for user identification in the above example where only the primary password was applied, the user database would be as follows.

RF card User name authority (cellphone) Card 1 Security Officer Super administrator (010-7777-7777) Card 2 CEO manager (010-5555-5555) Card 3 Temple Normal

In summary, a process of recognizing a user (inputting a primary password, biometrics, or RF card), transmitting a secondary password to a registered user's mobile phone, and receiving and confirming the transmitted secondary password It is possible.

In this case, a person intending to break into the system will not be able to open the door lock simply by acquiring an available password (primary password).

However, since it is inconvenient to always input a second password, depending on the security policy, for example, if a particular user first succeeds in authentication by a secondary password for a certain period of time (e.g., a day) During the day, you can operate it so that it does not ask for a second password. This security policy profile is also specified by the super administrator.

In the above example, the process of recognizing the user (inputting the first password, biometrics or RF card) and confirming that the second password was authenticated within a predetermined period, Otherwise, it is possible to transmit the secondary password to the mobile phone of the user, and to confirm the received secondary password again.

Another example is to send a secondary password prompt (voice and / or text) and send a secondary password to the user's phone if there is no input within a certain amount of time (eg 5 seconds). According to the security policy, if the secondary password transmitted to the user is valid for a certain period of time (eg, one day or one week), the secondary password already known by the user can be reused during that period. It is explained that it is possible to operate the door lock operation cost (eg, text message transmission cost) while applying the second password.

In the above example, a process of recognizing a user (inputting a first password, a biometric identification, or an RF card), a process of requesting a second password, a process of registering a second password Transmitting the secondary password to the user's mobile phone, and re-inputting the received secondary password.

The application of the above double security (secondary password) can be applied especially to the point where security is required. Also, if there is any indication that the security is considered to be abnormal, or if the company is in the holiday season, it may be implemented for security purposes.
