[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.

A procedure for counting a password inconsistency, a procedure for checking occurrence of inconsistency more than a predetermined number of times for a predetermined time, and a procedure for notifying a corresponding contact to a promised contact by the means promised. If a predetermined number of times is designated as " one time ", each time an incorrect password is input, the user will be informed of the fact by registered promised users (e.g., super administrator: home = mother, company = security person in charge).

[Notification of security anomalies and camera linkage]

Remote access or remote monitoring services are now common, allowing users to connect to remote cameras via a mobile phone or smart phone to monitor the status of remote locations. It is also possible that a user who is informed by a text message to the user when the security error signal indicating the wrong password is input can monitor and connect to the camera installed around the door lock or the door lock through the remote monitoring service.

It is convenient to use the "callback URL" that is currently generalized. According to the terminology dictionary, " Internet URL is left through a short messaging service (SMS), and when a mobile phone user presses a call button, the mobile phone is automatically connected to a wireless Internet site of the corresponding address. The connection can be simplified, and the downloading service and the use of the Internet information service can be activated. " That is, the callback URL confirms a text message notifying of a security abnormality indication, and when a [call] button of a mobile phone or the like is pressed, a wireless Internet connection is performed with a predetermined URL. Of course, since the predetermined URL has the remote access address of the camera, remote monitoring via the camera becomes possible.

The camera module may be provided in the door lock itself, but the production cost of the product is increased. Such a remote connection and remote monitoring function may be an additional function, so that it is possible to use a separate camera through a necessary user without installing a camera in the door lock itself. In other words, by designating a callback URL that can be connected to the separate camera in a text message for notifying a security abnormality in the door lock, the user can confirm the text message and press the [CALL] ) Of the present invention. In this case, the surveillance camera may be installed completely separately from the door lock, or may have only a callback URL that can be connected to the camera in the door lock (of course, a callback URL is set by the management function of the door lock) When the message is transmitted, the callback URL is provided to the user. For example, a text message such as "Password X times incorrect, press [Call] to connect to camera" is sent to the user. The advantage is that it does not provide the camera to the user who does not need the camera, so the product price can be kept low and the installation position of the camera can be freely installed.

As mentioned above, a camera module may be included in the door lock, a camera may be installed separately from the door lock, and a camera module may be installed in conjunction with the door lock. In the third case, only the interface module capable of connecting the camera to the door lock is provided. The connection between the door lock and the camera can be performed using a USB interface, which has been generally used recently, and a wireless interface module capable of wireless connection can be applied to simplify the installation. It is possible to use (26) and (36) in FIG. 2a as a "wired or wireless interface module" as an interface module for camera connection. See FIG.

[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.

[Dual security, Callback  or Callback to server  Secondary authentication by]

It is troublesome for the user to press the second password in the above-mentioned dual security. Therefore, after confirming the text message, the secondary authentication is performed by a procedure of pressing the [Call] button instead of inputting the secondary password indicated in the text message, and the door lock can be opened. This can also be implemented via a callback URL. In this case, a text message such as " Please press the [Call] button to open the door through the secondary authentication " is transmitted to the user.

The callback server for the secondary authentication is referred to as " secondary authentication server " for convenience. When the user confirms the call back by pressing the [Call] button within a predetermined time (e.g., one minute or two minutes) after the user confirms the text message, the server transmits an " open " order And the door lock is opened.

To do this, the following process is required.

The door lock notifies the " secondary authentication server " that the user's callback will be a user callback within a predetermined time, and transmits a message enabling the call back to the secondary authentication server to the user's cellular phone. Of course, the door lock has a unique ID (eg, a physical network ID, or an IP address or an identifier that uniquely identifies the door lock). The second authentication server receives the callback of the user, and at the same time the open order is given to the door lock, and the door lock is opened. This is illustrated in FIG.

A similar one is as follows. The door lock notifies the second authentication server of the second authentication request, and the second authentication server transmits the second authentication message to the mobile phone, instead of transmitting the message from the door lock to the user's mobile phone. When a callback is received from the user's mobile phone to the secondary authentication server, the secondary authentication server makes an order to open the door to the door lock. See FIG. 5b.

The method of the second authentication server becomes complicated as much as the server for the second authentication has to be operated and there is a difficult problem to guarantee the reliability of the system.

As a second authentication method by an easier callback, the following forms are possible. (Eg 010-xxxx-xxxx) or Internet phone number (eg 070-xxxx-xxxx) in the door lock itself if the mobile communication module (eg CDMA), wired LAN or Wi- . In this case, a message (voice or text message) requesting the secondary authentication is transmitted to the user's cellular phone which has been subjected to the primary authentication (e.g., password, RF card, fingerprint recognition, (For example, 010-xxxx-xxxx or 070-xxxx-xxxx) of the character message, the door lock system detects this and opens the door . Referring to FIG.

Considering the cost-effectiveness, the second authentication method using the second password seems to be realistic.

[External Power and Power Operation for Increasing Battery Life]

It is needless to say that one or more communication modules may be added to the wired / wireless communication module (e.g., CDMA, wired phone, WiBro, WiFi, ...) provided in the door lock of the present invention. A problem that is most worrisome when a communication module is added to the door lock is the battery consumption of the door lock due to the operation of the communication module. As rechargeable batteries (hereinafter referred to as "batteries") technologies are developing to the extent that electric vehicles are commercialized, there is a possibility that they will be solved in a short period of time. However, when the mobile communication (eg, CDMA) module is installed as a communication module at the current low-cost technology level, even if a double-capacity high capacity battery is mounted on the door lock, It is possible to estimate the battery usage time. If a Wi-Fi module is installed as a communication module, a shorter battery usage time can be predicted. Therefore, an external power connection (eg, an external power connection using an AC-DC adapter for a notebook PC or the like) is required. In this case, a fatal drawback is that the installation becomes cumbersome.

External Power - Wireless charging method

One of the currently available technologies is wireless charging technology, which has been used in high-end electric razors and notebook PCs. Wireless charging technology is said to have "electromagnetic induction" and "magnetic resonance". The magnetic resonance method is said to have a wider charging range (charging distance) than the electromagnetic induction method, and the magnetic resonance method is mostly used now. A disadvantage of wireless charging technology is that current technology does not have a wide charging range and low power efficiency to charge to supply. In addition, it is not yet popularized in terms of price to be adopted only for expensive high-end products.

External Power - POE method

* The use of wireless charging technology solves the simplification of installation, but there is a concern that the unit price of the product may increase. One method that can be used to simplify installation while using charging by wire is POE (Power Over Ethernet), which is a technology that has been used in the past. This is a communication module in which a wired LAN module is mounted and the remaining four wires except for the four wires used for data of eight wires of a LAN cable (UTP cable) are connected to a DC (DC) power supply It is used for supply. That is, when only a LAN cable is connected, power can be supplied to the power supply through two wires among eight wires in the LAN cable. It can be considered that a wired LAN module is provided as a communication module in the door lock, and a power supply is also supplied by a wired LAN cable (UTP cable) connected to the wired LAN module. To supply power to the door lock using the POE method, the door lock is connected to the door via a POE hub (or an Internet router or hub that supports the POE method) via a LAN. That is, the door lock supporting the POE scheme and the POE hub are used in pairs. The POE hub usually includes one or more LAN ports to which a LAN can be plugged. If a POE supporting port is provided even from only one LAN port among the plurality of LAN ports, the POE support port is used to connect the door lock to a LAN You can connect them. The POE hub is an internet hub that can supply the DC current of the voltage promised to the promised two strands of the eight wires of the LAN cable as described, and it has the function of the AC-DC adapter.

The advantage of the above method is that it is not necessary to replace the battery by providing only one POE hub while utilizing a low-cost wired LAN module (i.e., a wired LAN card for wired Internet) as a communication module Battery replacement was required) service is available. For example, in most cases, the wired Internet is getting into the living room. Since there is almost no obstacle from the living room to the front door, it is easy to wire a LAN (UTP line). Do not. 7A is an example of wiring to the ceiling, and FIG. 7B is an example of wiring to the bottom. The horizontal distance " L " from the power outlet to the door lock shown in Figs. 7a and 7b may vary depending on the environment of each home or office. If the power adapter is connected, It is advantageous that the length of the LAN can be freely cut and aligned.

It is preferable that a rechargeable battery is incorporated in the door lock in case of a power failure even when an external power source is connected through the POE system or the AC-DC adapter. Fortunately, in Korea, there is little power outage, and even if a power outage occurs, it is restored in a very short time. Therefore, it is enough that a small capacity rechargeable battery is installed in the door lock.

External Power - Large capacity battery for external power supply

Power supply by the POE method is stable, but the installation may be troublesome as the LAN must be physically connected to the door lock. The following is a realistic way to reduce the price burden when the wireless charging method is applied while supplementing the disadvantage of physically connecting the wires.

First, inside the door lock, a small capacity battery (which means a rechargeable battery, hereinafter referred to as "battery" for convenience) is built in which the door lock can be started for a certain period of time (eg 10 hours, 20 hours, ...). In order to operate the communication module at all times, the external power source must be connected as described, which supplies a DC current with a large capacity external battery. This large capacity battery works just like an AC-DC adapter.

If you connect an AC-DC adapter that acts as an external power source to the Notebook PC, you will find that the adapter's DC power source is also charged with the power needed to operate the notebook PC while charging the built-in battery. We also know that when the adapter is unplugged, the notebook PC recognizes that the external power supply has been cut off and is powered by the internal battery. When the power of the large capacity battery (hereinafter referred to as "large capacity battery") which is operated by the external power source is exhausted, the door lock is recognized as the external power source interruption and sound (voice / sound) or message Display indicates that a large capacity battery operating from the external power source needs to be charged.

The user removes the external large capacity battery which needs to be charged from the door lock, places it on the charging stand, and charges the small capacity battery built in the door lock during charging (for example, two hours). When the rechargeable large capacity battery is connected to the door lock, the large capacity battery acts like an AC-DC adapter to charge the small capacity battery in the door lock and supply the power for operating the door lock. The connection / disconnection between the door lock and the external large capacity battery can be implemented by a similar interface to a conventional AC-DC adapter and a jack connecting a device (eg notebook PC, door lock, etc.).

The details of the above circuit configuration are similar to the existing AC-DC adapter operation method, so they are not mentioned in detail. However, if the large capacity battery operated by the external power supply is consumed and less than the required voltage, the door lock should detect that the external power supply is cut off. In the case of an electronic device operated only by an external power source, when a voltage below a certain level is connected, it is detected that the external power source is not connected. For example, connecting a 1 volt adapter to a device that requires 10 volts is not working.

* It goes without saying that the above connection (eg connection of a large capacity battery, connection of a POE type LAN) is of course carried out inside the door (ie, inside the house, not on the outside corridor outside the house). (Such as a basket or a bag type) capable of fixing the large capacity battery of a door lock to be placed on the side of a house for connection of the large capacity battery. See FIG.

In this system, a large-capacity battery which can be connected to an external power source instead of an AC-DC adapter has been sold separately for extending the use time of the notebook PC when it is carried, and has already been proven. In other words, only the external AC-DC adapter can be connected, and only the external large-capacity battery can be provided. An advantage of the above-described method is that it is not troublesome to install a physical line to a door lock, and it is only required to provide a large capacity battery and a charging stand of the large capacity battery. However, there still exists the inconvenience that the large-capacity battery should be periodically charged to the door lock.

The POE system and the battery system for external power supply can coexist in one door lock, and thus it is possible to provide both interfaces to the door lock. In this case, according to the user's choice, the POE system can be used by connecting a LAN cable or by connecting a large capacity battery for external power supply. The DC power supplied from the POE method and the DC power supplied from the large capacity battery for the external power supply will operate normally even if the user supplies the power in two ways simultaneously.

Control of liquid crystal (LCD) operation by motion detection sensor

One of the characteristic features of the present invention is to add a liquid crystal display (LCD) to the door lock (display irrespective of whether or not the communication module is built-in) to display a message to PR itself, When a certain person opened the door, there was a specific message to the person.

Since the liquid crystal must emit its own light, it consumes more battery capacity than other parts. We know that notebooks, smartphones, and so on also consume much more power when you keep the liquid crystal on. Therefore, it is possible to activate the liquid crystal and display a PR message or the like only when a motion detection sensor is added to the door lock and it is detected that someone has approached (for example, within 1 m) from outside the door. Motion sensors are expected to consume less power than liquid crystals. In the reality that the life pattern is becoming personalized, since there is not a lot of time for someone to stay in front of the door of a family (eg apartment), the liquid crystal operation by this motion detection sensor will be meaningful.

A simpler method than the motion detection sensor is to detect when the user touches the door lock (eg, touch the keypad key, open the cover in the case of a door with a slide cover), the door lock starts to operate, . The motion sensor has the advantage that when someone approaches a certain distance (e.g., 2 m) from the door lock, the liquid crystal can start operating and the contact sensor operates only when someone (including the user) touches the door lock, However, there is a disadvantage in that a user who does not contact the door lock but can not display a message of the liquid crystal can be displayed.

There is an advantage that another application is possible when a motion detection sensor module or a contact detection sensor module is installed and a camera (including a recording function) is incorporated in the door lock itself or is interlocked with a camera through an external interface module. Products with cameras and expensive recording equipment are very expensive and expensive to install. However, a number of low-cost products have recently been introduced, which include a built-in memory and a recording function. When recording using the built-in memory of the camera itself, the memory capacity is low, so it is only possible to record for a very short period of time (for example, only a few days). However, when the operation or contact is sensed by interlocking with the motion detection sensor or the contact detection sensor, the signal is received by the control unit of the door lock and the recording start order is given to the camera linked to the built-in camera or the external interface module, Or in a state in which there is no contact, and is recorded only when an operation or a contact is detected, so that it is possible to record a long-term situation even with a small amount of memory. Also, even if you check the recording contents later, when there is no operation or contact, it is not recorded, so that only a meaningful scene can be searched easily. It is a matter of course that the recording is stopped to be stopped if no operation or contact is detected for a predetermined time (e.g., one minute) even if the operation is started when the operation or contact is detected. This can be easily implemented by driving the timer from the moment the final operation or contact is detected.

By using motion detection sensor or contact detection sensor, it is possible to control not only camera module but also communication module (eg CDMA wireless communication, WiBro, ..). That is, the communication module operates only when operation or contact is detected, thereby saving power (battery). Wi-Fi communication functions as described below When connected to a Wi-Fi AP, consumes a large amount of battery. Therefore, the communication module is activated only when operation or contact is detected, thereby minimizing battery consumption. As described in the camera, if the operation or contact is detected and no operation or contact is detected for a predetermined time (e.g., 1 minute, 2 minutes, etc.) even if the operation of the communication module is activated, the operation of the communication module is disabled, Consumption can be reduced, which can also be easily implemented using a timer function from the moment a final operation or contact is detected.

[ Wi-Fi  Function or Wi-Fi bridge  Addition of function]

Hereinafter, "Wi-Fi", "wireless LAN", "Wi-Fi wireless LAN" and the like are used in the same meaning. However, it goes without saying that the present invention can be equally applied to existing wireless communication services (e.g., CDMA wireless communication, WiBro, etc.) or other wireless services to appear in the future.

Currently, carriers are competing with their WiFi networks for load balancing of mobile communication networks. One of the examples is to distribute Wi-Fi home Internet telephony, and to distribute its wireless router (or Wi-Fi AP: Access Point) in the home. This AP allows other users to use wireless WiFi.

The spread of the AP through the home Internet phone has a disadvantage that the signal is weakly caught outside the home. By adding the Wi-Fi AP function to the door lock of the present invention, a path for smoothly providing Wi-Fi to users outside the house is opened. (Wired Internet) to a door lock using a POE hub or the like, and if the door lock functions as a Wi-Fi AP itself, the door lock (i.e., Wi-Fi AP) have.

If the door lock is equipped with a WAPI wireless LAN function as a communication module and a door lock signal is received from an AP installed in the house (or office), the door lock can be used as a WiFi bridge function As well. The radio signal from the AP installed in the house is rapidly weakened after passing through the main entrance door (mainly made of thick iron doors). However, a wireless LAN antenna (built-in or external) is added to a portion of the digital door lock that is exposed outside the door (e.g., a portion where a numeric keypad for inputting a password is input), and the door lock itself performs an AP function, ) To be able to transmit Wi-Fi signals farther outside. In recent years, a large number of wireless routers (APs), in which an antenna is not exposed to the outside, have been introduced. Therefore, application of an antenna built-in type is preferable in terms of design of a door lock.

The Wi-Fi bridge function connects two APs wirelessly. A wired Internet line is connected only to the first AP, and a wired Internet is not connected to the second AP, and a wireless (Wi-Fi) bridge is established between the two APs. The second AP, which is not connected to the wired Internet, operates the same as the first AP connected to the wired Internet, so that it is possible to extend the reach of the Wi-Fi radio without wired connection. This function is also included in a commercially available wireless router (AP).

For example, in the case of the present invention, a wired Internet is connected to a first AP installed in a living room, and a door lock, which is a second AP, has an effect of extending the distance of an AP from a living room to a door without being connected to a wired Internet . The following is an example of an apartment in connection with the present invention. In a state where the present invention is not applied, a Wi-Fi signal can be caught even in the corridor near the room 101 where the AP is installed in the house. However, if you go away from room 101 and go to room 108 where there is no AP installed in the house, you will not get a signal for the wafi. However, if the door lock provided in the present invention is installed in the room 101 and the door lock AP function (in the wired Internet direct connection or the Wi-Fi bridge mode) is provided, the Wi-Fi wireless LAN can be used smoothly in the entire corridor of the apartment will be. For the sake of convenience, it is obvious that it can be equally applied to the office environment.

The view from the outside of the house or office is shown in Figure 10 *. Figure 10b shows the camera or camera module installed together. When the wired LAN is connected to the door lock as shown in Fig. 7 *, since the door lock itself has the AP function, the outdoor side portion of the door lock of Fig. 10 * functions as the AP. In the case of being bridged wirelessly (eg, Wi-Fi) in a form similar to that shown in FIG. 8, the door lock exposed on the outdoor side in FIG. 10 * acts as an AP and provides smooth wireless communication services in the apartment Do. The electrical / circuit connection between the interior and exterior of the door lock can be achieved by electrical / circuit connection between the inside of the door lock and the outside of the door lock through the perforated part of the door for installation of the door lock as in conventional door locks Do.

In the case of a service provider (e.g., a communication company), providing the door lock service of the present invention to its customers and providing a Wi-Fi wireless LAN service to its other subscribers using the resources (front door, digital door lock, There is an advantage to be able to do.

Fig. 10c is a view showing the case where two external antennas are added to the door lock of Fig. 10a. FIG. 10D is a view showing the case where one external antenna is added to the door lock of FIG. 10C. Applying an internal antenna is, as mentioned, better in terms of design. Putting an external antenna can show that the door lock acts as an AP, and it can show off the door lock as a special function. It is also possible to provide a wireless service in a room with a wireless router function (or an AP function) at the POE hub (or POE router) installed indoors at the same time. An interior or exterior antenna may also be applied to the interior side of the door lock. FIG. 11 is a view showing an external antenna applied to the interior side portion of the door lock shown in FIG. A communication module that functions as an AP in a door lock is provided on one of the indoor or outdoor side portions of the door lock (preferably on the indoor side), and an antenna (built-in or external type) electrically / (Eg, Wi-Fi) on the inside and / or outside of the room. It is a matter of course that the communication module includes both an AP and an antenna.

By adding a communication function to a digital door lock and combining it with a general-purpose mobile phone, the user's need for security enhancement can be solved at a very low cost, and the user's member can be confirmed whether or not the user is in or out.
