Hereinafter, the detailed description of the preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the reference numerals to the components of the drawings it should be noted that the same reference numerals as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 is a diagram illustrating an internal configuration of a digital door lock according to an embodiment of the present invention.

The digital door lock of the present invention is characterized by having two modules (200, 250; indoor module, outdoor module) and two controllers (202, 260; indoor controller, outdoor controller) divided into an indoor side and an outdoor side. First, referring to each component of the indoor module 200, the indoor input unit 214 is implemented as a lock button, an operation mode button in the room and receives a digital door lock operation from the user in the room. The indoor output unit 212 includes audio output means such as a speaker, an LED, an LCD, and an image output means, so that the user of the indoor side can know the state of the digital door lock. Display and so on.

The indoor storage unit 216 is a memory capable of inputting and outputting information such as a flash memory, and stores authentication information for digital door lock authority approval. The authentication information is set by the user and registered in the indoor storage unit. The authentication information includes various known information such as password, iris information, fingerprint information, RF information, and the like. When there is a digital door lock operation request received from the user for predetermined authentication (hereinafter, referred to as 'request authentication information'), the indoor control unit 202 may request the authentication information and the authentication information in the indoor storage unit 216. Determines if the match matches, and performs the requested digital door lock operation only if it matches.

The indoor infrared transceiver 204 is a function unit for performing infrared communication with an outdoor infrared transceiver 258 located outdoors through an infrared transmission path 282. The indoor controller 202 receives infrared rays and converts the signals into digital signals. Will output As a result, various types of data generated by the indoor control unit 202 and the outdoor control unit 260 exchange data with each other through wireless infrared communication, not wired communication, using the indoor infrared transceiver 204 and the outdoor infrared transceiver 258. do. In addition, the indoor infrared transceiver 204 may receive infrared data directly from a separate remote controller (not shown in FIG. 2) instead of the outdoor infrared transceiver 258. That is, when the user inputs a password or the like through the keypad of the remote controller for the locking / opening request, and aims at the infrared transmission path outdoor entrance 284 and performs infrared communication, the indoor infrared transceiver 204 receives the remote control from the remote controller. The infrared light emitted may be received.

The indoor battery power source 206 serves to provide power to each of the functional units provided in the indoor module, and the outdoor battery power source 210 provides power to each of the functional units provided in the outdoor module 250. Perform the function. The outdoor battery power supply 210 performs a function of providing power to the outdoor module 250, but in order to prevent theft and unauthorized detachment from the outdoor side, the outdoor battery power supply 210 is located in the indoor module 200 and the door ( The power is supplied to the outdoor module 250 through 286. Therefore, the present invention, unlike the conventional digital door lock as described above, by separately providing two battery power, it is possible to provide the driving power of the indoor side and the outdoor side separately.

An outdoor battery power switch 208 is provided between the outdoor battery power source 210 and the outdoor module 250 to perform switching under the control of the indoor control unit 202. That is, in the switched on state, the power provided by the outdoor battery power 210 is supplied to the outdoor module 250. In the switched off state, the power provided by the outdoor battery power 210 is supplied to the outdoor module 250. Since it is not supplied to 250, it is possible to prevent unauthorized acts to unlock the digital door lock by inputting authentication information to the outdoor input unit 262. That is, when the user goes out with the outdoor battery power switch 208 switched off, each component of the outdoor module 250 is not operated because it does not receive the driving power, and thus, the digital input is performed through the outdoor input unit 262. The door lock release request cannot be attempted. As a result, in the switching-off state of the outdoor battery power supply, the door is opened by communicating with the indoor infrared communication unit 204 by aiming the portable remote control carried by the user at the infrared transmission path outdoor entrance 284.

An indoor controller 202 controls each of the functional units to control the locking / opening operation of the motor lock after a predetermined authentication operation, and outputs various locking / opening states through the outdoor output unit. Switching control of the outdoor battery power switch 208 is performed according to a predetermined condition.

Meanwhile, referring to each component of the outdoor module 250, the outdoor emergency power input terminal 252 is a terminal for temporarily supplying emergency power when the indoor battery power 206 is discharged, and is implemented as a diode bridge or the like.

The high voltage discharge LED 254 discharges a high voltage when the high voltage flows through the outdoor emergency power input terminal 252. The high voltage discharge LED 254 has a normal emergency power supply to the outdoor emergency power input terminal ( When flowing through the 252, the driving is not performed, but when the high voltage flows through the outdoor emergency power input terminal 252, the high voltage may be discharged by light emission of the high voltage discharge LED 254. This is because when a high voltage of more than a predetermined value is introduced, the discharge amount (emission) of the high voltage discharge LED 254 increases, and when a voltage of a predetermined value or less flows in, the discharge amount (emission) of the high voltage discharge LED 254 decreases. Will be used. The ground required for the high voltage discharge LED 254 to be electrically discharged is connected to the case of the door of the conductor rather than the ground of the outdoor module or provided with a separate ground plate to separate the ground required for LED discharge of the outdoor module. It can have a circuit configuration that ensures independent of the system ground.

The emergency power bypass unit 256 performs a function of bypassing the electric power introduced from the outdoor emergency power input terminal 252 to the indoor module 200 under the control of the outdoor controller 260. That is, when emergency power is introduced from the outdoor emergency power input terminal 252, the user's authentication information is checked, and when the bypass authentication is successful, the power flowing into the outdoor emergency power input terminal is sent to the indoor module. On the other hand, when the authentication information of the user is wrong due to the authentication failure, the power flowing from the outdoor emergency power input terminal 252 is cut off so as not to be transmitted to the indoor module 200.

The outdoor input unit 262 receives a function of inputting authentication information (eg, password, hereinafter, request authentication information) for digital door lock opening and closing request from a user who is outdoors. The outdoor output unit 264 is composed of audio output means such as a speaker, LED, LCD, and image output means so that the user of the outdoor side can know the state of the digital door lock, the voice generated according to the state of the digital door lock, alarm sound, guidance Display is performed outdoors.

The outdoor storage unit 266 is a memory capable of inputting / outputting information such as a flash memory, and stores authentication information for determining whether to pass / block the emergency power bypass unit 256 in an emergency mode. The authentication information is the same authentication information stored in the indoor storage unit 216. The authentication information such as a password and iris information registered when the user uses the digital door lock for the first time is stored in the indoor storage unit 216 and the outdoor storage unit. Are stored simultaneously at 266. As described above, the outdoor storage unit 266 stores authentication information separately from the indoor storage unit, such that the indoor battery power source 206 of the indoor module is discharged to receive emergency power from the outdoor emergency power input terminal 252. In the mode operation, the emergency power bypass unit receives the predetermined request authentication information from the user through the outdoor input unit 262 and only when the received request authentication information and the authentication information in the outdoor storage unit 266 match with each other. Drive 256 to send the emergency power to the indoor module (200).

The outdoor infrared transceiver 258 is a function unit that performs infrared communication with the indoor infrared transceiver 204 located indoors through the infrared transmission path 282. It converts and outputs to the indoor infrared transceiver 204, and performs infrared communication from the indoor infrared transceiver 204 to output to the outdoor controller 260 after digital conversion. As a result, various types of data generated by the indoor control unit 202 and the outdoor control unit 260 exchange data with each other through wireless infrared communication instead of wired communication through the indoor infrared transceiver 204 and the outdoor infrared transceiver 258. .

The outdoor controller 260 transmits the information input through the outdoor input unit 262 to the indoor module 200 by using the outdoor infrared transceiver 258, and further, the outdoor emergency power input terminal ( 252 to check whether there is a voltage inflow, and when the normal voltage inflow and bypass authentication is successful, the emergency power bypass unit 256 is opened to send emergency power to the indoor module 200. When the emergency power is supplied from the outdoor emergency power input terminal due to the discharge of the battery power in the indoor module 200, the user receives the requested authentication information together with the authentication information in the outdoor storage unit 266, and bypass authentication. Only when successful, the power of the outdoor emergency power input terminal 252 is supplied to the indoor module 200. On the other hand, when the bypass authentication fails, the emergency power bypass unit 256 is blocked to prevent the voltage flowing through the outdoor emergency power input terminal 252 from being transmitted to the indoor module 200.

3 is a flowchart illustrating a process of bypassing emergency power to an indoor module by an outdoor controller according to an embodiment of the present invention.

When the outdoor input unit 262 receives the request authentication information (for example, a password, etc.) for the digital door lock operation as the predetermined request authentication information (S302), the outdoor control unit 260 receives emergency power through the outdoor emergency power input terminal. It is determined whether there is (S304). The determination (S304) may determine whether the input is received by the outdoor control unit 260 receives the output signal of the outdoor emergency power input terminal. For example, when the outdoor emergency power input terminal 252 is implemented as a diode bridge, it receives the positive (+) side output value of the diode bridge and determines that the emergency power is being supplied when the output value is high. (Low), it is determined that emergency power is not supplied.

As a result of the determination (S304), when the emergency power is not supplied, the request authentication information and other data are transmitted to the indoor module 200 through the infrared transmission path 282 as in the normal operation (S310). . In the normal mode in which the indoor battery power is normally supplied, the indoor module receives the request authentication information (S310) and performs a predetermined digital door lock locking / opening operation. However, even if the indoor module is not normally driven while the indoor battery power is discharged, even if the request authentication information is transmitted to the indoor module as described above (S310), the indoor infrared transceiver of the indoor module is turned off. ), So that no request authentication information can be received, and as a result, the digital door lock does not perform any operation.

On the other hand, if it is determined that the emergency power is input to the outdoor emergency power input terminal 252 (S304), and when it is determined that the emergency power is input, the request authentication information received through the outdoor input unit 262 is outdoor. It has a bypass authentication process (S306) for determining whether or not match with the authentication information registered in the storage unit 266. As a result of determination (S306), if authentication fails due to a match, all processes are terminated without any bypass processing, and the request authentication information of the outdoor input unit 262 and the authentication information of the outdoor storage unit 266 match and bypass. If the authentication is successful, the emergency power bypass unit 256 is opened to bypass the emergency power flowing through the outdoor emergency power input terminal 252 to the indoor module 200 (S308), and then request authentication. Information is transmitted to the indoor module through the infrared transmission path (S310). The indoor module 200 has a driving off state due to the discharge of the indoor battery power source 206 and is driven (on) by the emergency power flowing through the emergency power bypass unit 256. The request authentication information transmitted through the infrared transmission path 282 can be received. The indoor control unit 202 performs authentication comparing the authentication information of the indoor storage unit 216 with the request authentication information, and performs a digital door lock operation according to the authentication result.

As a result, looking at the features of the digital door lock of the present invention as follows. The digital door lock of the present invention is divided into an indoor side and an outdoor side, having a first feature having two modules (200, 250; indoor module, outdoor module), and infrared transmission and reception of data transmission and reception between the indoor module 200 and the outdoor module 250. The second feature of wireless infrared communication through the passage 282, and the power supply to the indoor module 200 and the outdoor module 250 to the two battery power (206, 210; indoor battery power, outdoor battery power) separately It has a 3rd characteristic which improved the door lock security by providing.

First, referring to the first feature designed by dividing the indoor module 200 and the outdoor module 250, the digital door lock according to the present invention includes an indoor control unit 202 (indoor MCU) and an outdoor unit on an indoor side of the door. An outdoor controller 260 is provided on each side to allow the indoor controller 202 to control the locking / opening operation of the mortise lock 280 after a predetermined authentication, and causes the outdoor controller 260 to control the outdoor side. Infrared transmission of the information data received from the indoor side. As described above, since the indoor control unit 202 is configured as an independent system for controlling the indoor module 200 and the outdoor control unit 260 separately to the outdoor module 250 (designed independently to the ground), it is introduced from the outdoor. It is possible to fundamentally prevent being hacked by the high-pressure noise. By separating the indoor module 200 and the outdoor module 250 as described above, when emergency power flows from the outdoor emergency power input terminal 252, only after a predetermined authentication is successful in the outdoor module 250, the emergency By transmitting power to the indoor module 200, security was improved.

In addition, referring to the second feature of wirelessly communicating data between the indoor module 200 and the outdoor module 250 through an infrared transmission path, the indoor module 200 and the outdoor module 250 are not wired but infrared transmission paths. 282 is a wireless infrared communication, which is to prevent the overvoltage flows into the wire connected to the indoor indoor control unit 202 when hacking with a high voltage generator to the outdoor emergency power input terminal 252 from the outdoor side. Sending and receiving data using a wireless infrared transmission path.

In addition, referring to the third feature of increasing door lock security by separately providing two battery power sources 206 and 210 (indoor battery power and outdoor battery power), the power supply of the indoor module 200 and the outdoor module 250 is separately provided. This can improve the door lock security. In addition, by switching on / off the outdoor battery power 210 supplied to the outdoor module 250, only the components (eg, the outdoor input unit, etc.) of the outdoor module 250 can be driven on / off to secure the digital door lock. Improved sex.

On the other hand, the digital door lock according to the present invention has the following features in addition to the above three features to further improve the security.

Features of digital door lock processing algorithm according to temperature change (hereinafter referred to as fourth feature) and processing algorithm feature of indoor handle operation (hereinafter referred to as fifth feature) in order to prevent illegal door lock opening and fire response treatment using a heat generator such as a torch car. ) In order to implement the fourth and fifth technical implementations, the digital door lock of the present invention further includes a configuration block as shown in FIG. 4 in addition to the configuration block of FIG. 2.

4 is a diagram illustrating an internal configuration block of a digital door lock according to another embodiment of the present invention.

The digital door lock according to another embodiment of the present invention further includes an outdoor temperature sensor, an indoor temperature sensor, an indoor handle manipulation sensor, an indoor manual lock sensor, a motor driver, and a lock / open sensor in the component block of FIG. 2. The outdoor temperature sensor 412, the indoor temperature sensor 410, the indoor handle operation detection sensor 402, the indoor manual lock detection sensor 408, the motor drive unit 406, the lock / open detection is added in the configuration block of FIG. The sensor 404 is shown in bold solid lines in FIG. 4.

The motor driver 406 operates the mortise lock 280 to open the door 286 according to the drive signal of the indoor control unit 202. The mortise lock 280 locks the door by using a solenoid. Perform a mechanical function of opening / opening. The lock / open detection sensor 404 performs a function of detecting the lock / open of the digital door lock.

The indoor temperature sensor 410 generates an interrupt of an indoor temperature abnormality detection signal and transmits it to the indoor controller 202 when the indoor temperature is higher than a preset temperature value (eg, 55 degrees). Similarly, the outdoor temperature sensor 412 generates an interrupt of the outdoor temperature abnormality detection signal when the outdoor side temperature is higher than a preset temperature value (eg, 55 degrees) and transmits it to the outdoor control unit 260. Is transmitted to the indoor control unit 202 through the infrared transmission communication path 282. The indoor temperature sensor 410 and the outdoor temperature sensor 412 may be implemented by various temperature sensors such as resistance temperature sensors, thermistors, thermocouples, bimetals, and radiation thermometers.

The indoor control unit 202 receiving the indoor temperature abnormality detection signal and the outdoor temperature abnormality detection signal performs control of warning alarm output and digital door lock unlocking according to whether the indoor temperature abnormality detection signal and the outdoor temperature abnormality detection signal are detected. It will be described in detail with the flowchart.

On the other hand, the indoor handle operation detection sensor 402 is a sensor that detects the handling of the handle (open button) provided in the indoor side, the digital door lock when the user makes a specific operation on the handle provided in the indoor side It is unlocked so that the door can be opened. The indoor handle manipulation detection sensor 402 is a sensor for detecting what specific handling is performed on the handle provided in the indoor side.

The indoor manual lock detection sensor 408 is a sensor for detecting whether the indoor lock is in the manual lock mode by the user's setting. The manual lock mode is an operation button installed at the indoor side, an operation handle and an outdoor side. It is a mode that prohibits all indoor and outdoor operations such as operation. When the digital door lock is set to the normal normal mode, the outdoor side operation and the indoor side operation are normally performed, but when the manual door lock mode is set, neither the indoor side operation nor the outdoor side operation is performed.

For example, when the manual lock mode is set, all the operation buttons of the indoor side as well as any outdoor operation such as button input and remote control input of the outdoor side are not performed. When the manual lock lever 502 is set to the manual lock mode 504 as shown in FIG. 5, the indoor manual lock detection sensor 408 detects this and sends an interrupt signal to the indoor controller 202 to indicate that the manual lock mode is set to the manual lock mode. send. The indoor control unit 202 receiving the interrupt signal ignores all operation signals input from the indoor side and the outdoor side and does not perform any operation. By setting it to the manual lock mode as described above, it is possible to prevent unauthorized intruders from opening the door illegally by inserting a predetermined mechanism through the milk inlet of the door and pressing the door opening button on the indoor side.

The manual locking mode may be set by a manual locking lever provided in the indoor side of the digital door lock as shown in FIG. 5, but the manual locking mode may be set by using a remote controller in the outdoor side when going out. The manual lock mode can be released by using the remote controller only when the manual lock mode is set by the remote controller at the outdoor side when going out. This is because it can only be authenticated if it can be resolved. For reference, in FIG. 5, when the manual lock lever provided in the indoor side is set to the mechanical key locking mode 508, this refers to a mode that does not perform key operation on the outdoor side.

As described above, the digital door lock of the present invention includes an indoor handle operation detection sensor and an indoor manual lock detection sensor, and a predetermined control algorithm when the indoor handle is operated while the motor is operated to lock / open the digital door lock (Fig. 7 flowchart) and a predetermined control algorithm (Fig. 8 flowchart) when operating in the manual lock mode, which will be described in detail with the flowcharts of Figs.

6 is a flowchart illustrating an algorithm of an indoor control unit that receives an indoor temperature abnormality detection signal and an outdoor temperature abnormality detection signal according to an exemplary embodiment of the present invention.

Referring to FIG. 6, when the indoor controller 202 receives an indoor temperature abnormality detection signal or an outdoor temperature abnormality detection signal from either the indoor temperature sensor 410 or the outdoor temperature sensor 412 (S602), When the indoor control unit 202 receives only an indoor temperature anomaly detection signal first (S604), when only an outdoor temperature anomaly detection signal is first received (S608), the indoor control unit 202 simultaneously receives an indoor temperature anomaly detection signal and an outdoor temperature anomaly detection signal. Predetermined control is performed by distinguishing each case (S612).

That is, when only the indoor temperature abnormality detection signal is received first and the outdoor temperature abnormality detection signal is not received (S604), the indoor control unit 202 opens the locking device (eg, dead bolt) of the digital door lock and generates a warning alarm ( S606). This is a case where the room temperature rises first due to a fire or the like on the inside of the door, and automatically unlocks the digital door lock and generates an evacuation warning alarm so that the living room in the room can easily escape (S606). )

On the other hand, when the indoor temperature abnormal detection signal is not received and the outdoor temperature abnormal detection signal is received first, only the illegal intrusion warning alarm is output (S610). This is a case where the outdoor temperature sensor first detects an abnormal temperature, and attempts to illegally open the door by disabling the electronic circuit of the digital door lock using a heat generator such as a torch on the outside of the door. Therefore, the illegal intruder breaks the electronic circuit inside the digital door lock due to a high temperature and attempts to release the lock of the digital door lock, thereby generating an illegal intrusion warning alarm (S610).

On the other hand, when the indoor temperature abnormality detection signal and the outdoor temperature abnormality detection signal are received at the same time (S612), the lock of the digital door lock is opened and at the same time generates a warning alarm (S614). This is a case where a fire occurs indoors and outdoors at the same time, it automatically opens the lock so that the indoor living room can be evacuated and at the same time generates an evacuation warning alarm.

FIG. 7 is a flowchart illustrating an operation process when the indoor handle is operated while the motor is operated to open and close the lock of the digital door lock.

In order to open and close the lock of the digital door lock, there was a fear that the motor overload would occur if the manual operation was performed by the user during the motor operation. Therefore, in order to prevent such an overload, the present invention includes a control algorithm as shown in FIG.
