The present invention relates to an auxiliary key type digital door lock that is automatically released when the door handle is operated. More specifically, the door handle operation characterized in that the self-deployment is developed by sensing the movement of the door handle generally installed on the door or recognizing that a part of the human body (especially the hand) is in contact with the door handle. The present invention relates to an auxiliary key type digital door lock which is automatically unlocked at the time.

In general, the door lock is a security device that is mounted on the door to secure the door to the door frame or release the state fixed to the door frame according to the user's operation. The door lock is installed as an opening and closing device in the front door of a general house, the entrance door of an apartment or office, and the safe of a bank, thereby preventing illegal intrusion of outsiders. Such door locks are roughly classified into mechanical door locks and digital door locks (DDL). The digital door lock is roughly divided into a primary key type digital door lock which integrally forms the door handle and an auxiliary key type digital door lock which separates and forms the door handle.

The auxiliary key-type digital door lock is largely composed of an inner operation part installed on the indoor side, an outer operation part installed on the outdoor side, and a mortise part disposed therebetween. In addition, the door handle is separately installed inside and outside to allow the door to be opened and closed. The inner control panel and the outer control panel are devices for controlling the operation of the mortise section, and are usually composed of a combination of mechanical devices and electronic devices. In addition, the mortise portion is a power generator (drive motor) for generating a physical force in response to the signals input to these control unit to perform the locking operation and the unlocking operation and the interlocking device (dead) to control the locking state and the unlocking state in response thereto. Bolts). Referring to the operation method of the conventional auxiliary key-type digital door lock is configured as follows.

When the door is to be opened from the outside: When a valid door lock release request signal (for example, key input or password input) is input through the outer operation unit, the drive motor is operated. The drive motor transmits the driving force to the drive lever through a power transmission means connected to the motor shaft. Then, the dead bolt is reversed (goes in the door inner direction) by the drive lever to set the unlocked state. Then, the user can open the door by operating the door handle provided on the outdoor side.

㉡ To open the door from the indoor side: If a valid door lock release request signal (for example, lock state release input or lock state release button operation) is input through the inner operation unit, the door may be opened by the method described above. It becomes possible.

By the way, when the auxiliary key-type digital door lock is installed in the door, it was possible to operate the door handle after prior to the release of the auxiliary key-type digital door lock to go out from the room. However, this acts as a bad news in the event of a fire or emergency in the room. In other words, the door can be opened only after several steps, so that it is impossible to quickly escape to the outside. In addition, if there is no emergency situation, the above steps may not occur smoothly. This can cause large accidents such as human injury.

Specifically, the present invention is characterized in that the auxiliary key-type digital door lock is automatically unlocked through the sensing device when the sensing device senses the movement of the door handle or a part of the human body (especially the hand) contacts the door handle. Then, an emergency evacuation is possible even in an emergency such as a fire or an emergency, thereby achieving a safety securing effect. Hereinafter, the configuration of the main features of the present invention described above will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the internal configuration of the auxiliary key-type digital door lock according to an embodiment of the present invention. As shown in FIG. 1, the auxiliary key type digital door lock according to a preferred embodiment of the present invention (hereinafter, abbreviated as 'secondary key') 100 is in the technical field to which the design belongs and the prior art in the field. As described, the outer operation unit 110, the inner operation unit 120, and the mortise unit 140 are configured to be included.

The display unit 114 may be implemented as a speaker or a display device. In the implementation of the present invention, the display unit 114 may not be provided.

The authentication controller 122 performs a function of determining whether the authentication information input to the key input unit 112 matches the authentication information stored in the memory unit 126. The authentication controller 122 may be implemented as a microprocessor unit that includes an authentication algorithm.

The door lock control unit 124 performs a function of controlling the overall operation of the components constituting the auxiliary key 100. For example, the door lock controller 124 generates a driving signal when the authentication success signal indicating that the authentication information input through the key input unit 112 matches the authentication information stored in the memory unit 126 is received from the authentication control unit 122. Then, the door lock control unit 124 transmits the generated drive signal to the lock driver 128 to cause the lock driver 128 to set the auxiliary key 100 to the unlocked state. In addition, the door lock control unit 124 transmits the generated driving signal to the display unit 114 to provide the display unit 114 so that the user can recognize that the auxiliary key 100 is set to the unlocked state. On the other hand, when the door lock control unit 124 receives the authentication failure signal from the authentication control unit 122, it provides this fact to the user through the display unit 114. The door lock control unit 124 may be implemented by a general microprocessor.

The memory unit 126 stores authentication information used to determine whether the authentication information input through the key input unit 112 is a true user or a false user. Alternatively, the memory unit 126 stores a password.

The lock drive unit 128 includes an electric motor, and moves the mortise unit 140 to a ruled position or a unlocked position using electrical energy. In general, when the information input through the key input unit 112 is matched with the information stored in the memory unit 126, the door lock control unit 124 drives the lock drive unit 128 to the auxiliary key 100 by the mortis unit 140 ) Is released.

The power supply unit 130 serves to supply power to the auxiliary key 100 so that the auxiliary key 100 can operate smoothly.

The signal detecting unit 134 performs a function of sensing the movement of the door handle in the embodiment of the present invention. In addition, the signal detecting unit 134 performs a function of detecting whether a part of the human body contacts the door handle in the embodiment of the present invention. The signal detecting unit 134 may be implemented using a sensor, an inverter, a mechanical switch, or the like that detects heat or capacitance generated from a human body. A more detailed description of the signal detection unit 134 will be described below with reference to the later drawings.

The sensing data analysis unit 136 performs a function of interpreting the data acquired by sensing the signal detection unit 134 in the embodiment of the present invention. In detail, the sensing data analyzer 136 determines whether the sensing data includes information on the movement of the door handle or information indicating that a part of the human body is in contact with the door handle. The sensing data analyzing unit 136 notifies the door lock control unit 124 of the fact that the sensing data includes the above information. Then, the door lock controller 124 automatically releases the auxiliary key 100 through the lock driver 128 based on this. The sensing data analysis unit 136 may be implemented as a microprocessor equipped with a sensing data analysis algorithm to perform the above-described functions.

Next, for example, a method of sensing whether the signal detecting unit 134 rotates by operating the door handle or whether a part of the human body is in contact with the door handle will be described. In order to realize this, the signal detecting unit 134 is implemented using a sensor, an inverter, a mechanical switch, or the like that detects heat or capacitance generated in a human body. Hereinafter, a method of configuring and sensing the signal detecting unit 134 using each of them will be described. 2A and 2B are exemplary views illustrating a signal detection unit provided in an auxiliary key according to a preferred embodiment of the present invention.

Ⓐ Sensor that detects heat or capacitance generated in the human body

The first signal detecting unit according to the present invention is implemented with a human body detecting sensor for detecting a human body. As the human body detecting sensor, a pyroelectric sensor or PIR (Pyroelectric Infrared) sensor, which is an infrared temperature sensor that detects (ultra) infrared rays generated in the human body, may be used. In particular, LHi874 / 878, a pyroelectric detector, may be used as the human body detection sensor. The human body generates heat by itself and emits infrared rays. Invisible to the naked eye, these infrared rays have longer wavelengths than visible light in the electronic spectrum. In particular, the infrared radiation emitted from the human body is about 9.4 ㎛ long wavelength. The human body sensor uses the pyroelectric effect in consideration of this. That is, the human body sensor converts incident infrared rays having a predetermined range of wavelengths into a voltage form through a field effect transistor (FET) device to enable photodetection. In addition, the human body sensor processes light rays having a wavelength outside the range through the filter window. Meanwhile, in order to realize this, the first signal detecting unit may further include a Fresnel lens for collecting heat energy emitted from the human body and an IR filter for passing only wavelengths in the infrared region.

However, in the implementation of the present invention, the range of the human body sensor provided in the first signal detecting unit is not limited to the infrared sensor. For example, the human body detection sensor may be provided as an operation sensor for detecting a human operation state or a capacitance detection sensor for detecting capacitance generated by contact of the human body. When the capacitive sensor is provided as a human body sensor, for example, Korean Patent Registration Publication No. 342,736 "Sensing Circuit Using Capacitance Change" may be considered. Since the first signal detecting unit using the motion sensor or the capacitive sensor may be easily designed by those skilled in the art, detailed descriptions thereof will be omitted in the present invention.

An embodiment of the first signal detection unit is shown in FIG. 2A. Referring to FIG. 2A, an auxiliary key 100 is provided at one side of the door 200, and a first signal detection unit 210 is provided at the bottom of the auxiliary key 100. And, the door handle 202 is provided at a predetermined distance under the auxiliary key 100. In such an embodiment, the first signal detecting unit 210 may be configured so that the sensors provided downward. The reason is to realize the sensing only for the human body in contact with the door handle. When a person in the room touches the door handle 202 to go out, the first signal detecting unit 210 detects this and generates sensing data. Thereafter, the first signal detecting unit 210 provides the generated sensing data to the sensing data analyzing unit 136.

Meanwhile, in the embodiment of the present invention, the first signal detecting unit 210 is not limited to being installed at one end of the auxiliary key 100. For example, the first signal detecting unit 210 may be installed at one side of the door handle or near the door handle. In this case, it is preferable that the first signal detecting unit 210 has a communication means so as to perform wired or wireless communication with the auxiliary key 100.

Ⓑ inverter

The second signal detection unit according to the present invention is implemented with an inverter. In general, an inverter refers to a power converter for converting DC power to AC power or a power converter for controlling voltage and frequency of AC power. The inverter converts commercial AC power into DC power using a power semiconductor device (eg, a diode, a thyristor, a gate turn off thyristor (GTO), a transistor, an insulated gate bipolar transistor (IGBT), etc.) It performs the function of converting to an alternating frequency of arbitrary frequency and voltage. Then, this allows the inverter to control the rotational speed, magnetic flux, torque, etc. of the device such as an electric motor. The inverter is generally composed of a converter unit for converting a commercial AC power source to a DC power source, a smoothing circuit unit, an inverter unit for cutting the DC power source to an AC power source having a changed voltage and frequency, and a control circuit unit for controlling them.

The inverter performs the function of measuring the speed of the device first. The present invention uses this characteristic of the inverter. This will be described in detail as follows. In the present invention, the second signal detection unit is opened at one side of the door handle or near the door handle. At this time, the second signal detection unit is connected to the auxiliary key 100 by wire or wireless. And, for this purpose, the second signal detecting unit further includes a communication unit. The communication unit may use RF, IrDA, Bluetooth, and the like in wireless communication. However, in the implementation of the present invention, when the second signal detection unit includes an inverter having a built-in communication function such as Starvert iG5 produced by LSIS, it is not necessary to provide a separate communication unit. Under this configuration, the inverter of the second signal detecting unit measures the value when the door handle is rotated by the attraction force. Then, the second signal detection unit converts the value measured by the inverter into a pulse and notifies the sensing data analysis unit 136 of this. The sensing data analysis unit 136 determines whether the door handle moves based on this and performs an appropriate function.

In the present invention, it is also possible to use the power conversion characteristics of the inverter. The description is as follows. The second signal detection unit according to the present invention opens an inverter provided on one side of the door handle. In this case, wired or wireless communication is performed between the second signal detection unit and the inverter. A photodiode is used as the power semiconductor element constituting the inverter. In the present invention, the inverter communicates with the second signal detecting unit at predetermined time intervals or from time to time. Under such a configuration, when a human hand comes into contact with a door handle provided with an inverter, a noise signal is mixed into a communication signal by generating an induced signal. Then, the output signal is not smoothly output. The second signal detector generates sensing data based on this and provides the sensing data to the sensing data analyzer 136. On the other hand, in this case it is preferable that the door handle is not made of a metal material. The reason is that when the door handle is formed of a metal material, it can cause the same effect as when a human hand is in contact. On the other hand, when the door handle is formed of a metal material, it is preferable to shield the side of the inverter contacting the door handle with a wire mesh material. At this time, the wire mesh material is grounded. The door handle then does not cause the same effect as when a human hand touches it.

One embodiment of the second signal detection unit according to the present invention is as shown in FIG. 2B. Referring to FIG. 2B, when the person in the room operates and rotates the door handle 202 to go out, the second signal detecting unit 220 measures the speed of the door handle 202. Then, the second signal detection unit 220 generates the sensing data based on this. Thereafter, the second signal detecting unit 220 provides the generated sensing data to the sensing data analyzing unit 136.

Ⓒ mechanical switch

The third signal detecting unit according to the present invention is implemented with a mechanical switch. In general, a mechanical switch realizes a different value of behavior depending on an external input (i.e., whether the current state is set to On or Off). The present invention considers these characteristics of mechanical switches. That is, when a person operates and rotates the door handle, the mechanical switch recognizes this and is set to the on state. Then, the third signal detection unit generates the sensing data based on this and provides it to the sensing data analysis unit 136. On the other hand, when a person does not operate the door handle, the mechanical switch remains off. Then, the third signal detection unit does not perform any function.

On the other hand, the mechanical switch in the present invention can also be installed on one side of the door handle in a touch type. In such a case, when the human hand comes in contact with the mechanical switch, the switch is set to the on state. Conversely, if the human hand does not touch the mechanical switch, the switch remains off. The third signal detector detects the state of the switch to generate sensing data, and provides the sensing data to the sensing data analyzer 136. On the other hand, in this case, it is preferable that the third signal detection unit includes a device for detecting the state of the mechanical switch. The device for detecting the state of the mechanical switch may be implemented as described, for example, in Korean Patent Registration No. 128,546 "Mechanical Switch Sensing Device".

Next, the operation method of the auxiliary key 100 according to a preferred embodiment of the present invention configured as described above are as follows. 3 is a flowchart illustrating a method of operating a supplementary key according to a preferred embodiment of the present invention.

Referring to FIG. 3, the signal detecting unit 134 of the auxiliary key senses the door handle 202 in a predetermined time unit or from time to time (S300). However, in case of emergency, when an emergency situation occurs, a person operates the door handle 202 by using his hand to go out from the interior (S310). Then, the signal detection unit 134 senses this to generate the sensing data (S312). Thereafter, the signal detecting unit 134 transmits the sensing data to the sensing data analyzing unit 136, and the sensing data analyzing unit 136 analyzes the sensing data to determine whether the door handle 202 is operated (S320). ). When it is determined that the door handle 202 has been operated, the sensing data analysis unit 136 notifies the door lock control unit 124 of this fact (S322). Then, the door lock control unit 124 performs an automatic unlocking function through the lock driving unit 128 and the mortise unit 140 (S330). In the present invention, if such a step (S310 to S330) is passed, it is possible to easily open the door 200 only by operating the door handle 202 even if an emergency occurs.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention belongs may make various modifications, changes, and substitutions without departing from the essential characteristics of the present invention. will be. Therefore, the embodiments disclosed in the present invention and the accompanying drawings are not intended to limit the technical spirit of the present invention, but are intended to explain, and the scope of the technical idea of the present invention is not limited by the embodiments and the accompanying drawings. .
