The present invention relates to a digital door lock system and a control method for notifying the open state of a window when a user goes out. More specifically, when the digital door lock attached to the door receives an outgoing lock command from the user, the alarm sound stored when the window is opened by requesting and receiving information on whether the window is opened or closed from the open / close detection device attached to the window is determined. The present invention relates to a system and a control method of immediately notifying a user of an open state of a window by outputting a light or flashing a warning light.

 Currently, homes, shops, government agencies, and businesses are widely using access control systems to restrict unauthorized outsiders from entering. Access control systems are used in many forms, ranging from simple, low-cost locks to expensive mechanical devices with complex mechanical mechanisms, and electronic devices that combine mechanical technology with electronic technology.

The simple lock realizes the opening and closing of the door by the mechanical matching of the key and the lock, but the number of keys to be carried increases proportionally as the number of devices that require access control, such as a house, a car, a computer, and a safe, increases proportionally. While there is a disadvantage in that it is difficult to carry, there is also a problem in that it is not easy to find a key corresponding to a specific lock in a key package.

The open / close detection unit 212 may be implemented using various sensors or switches. Examples of sensors applicable to the open / close detection unit 212 include an infrared sensor, an optical sensor, a magnetic sensor, and an ultrasonic sensor. . Each sensor detects whether a window is opened or closed by using a change in the physical quantity, and outputs an electrical signal such as an analog signal or a digital signal.

In addition, a switch applicable to the open / close detection unit 212 includes a mechanical switch, an infrared switch, an optical switch, a magnetic switch, and the like, and each switch has a specific pulse signal, for example, a high signal (' 1 ') or low signal' 0 'is generated and transmitted.

That is, the signal output from the open / close detection unit 212 and input to the signal transmission unit 212 has a value of '0' when the window is locked and has a value of '1' when the window is open. It is a signal.

On the other hand, the opening and closing detection unit 212 according to an embodiment of the present invention is different depending on the type of sensor ('analog sensor' or 'digital sensor') or the type of switch ('NO switch' or 'NC switch'). Has a configuration. That is, when the open / close detection unit 212 that detects whether the window is opened or closed is a digital sensor, the high signal is transmitted to the signal transmitter 214 when the window is opened, and the low signal is transmitted when the window is closed. 214).

On the other hand, when the open / close detection unit 212 is an analog sensor, the analog signal output from the analog sensor is input to an analog to digital converter (not shown), and is converted into a digital signal by the A / D converter to convert the signal. It is input to the transmission unit 214. Of course, the digital signal output from the A / D converter is a high signal when the window is open, and a low signal is output when the window is closed.

On the other hand, the configuration of the open and close detection unit 212 according to the type of the switch will be described in more detail in FIG.

The signal transmitter 214 transmits the window open / close state signal having a digital value of '0' or '1' input from the open / close detection unit 212 to the digital door lock 220 using wired or wireless communication. It includes a digital communication module for performing the. The signal transmission method between the window monitoring unit 210 and the digital door lock 220 according to an embodiment of the present invention uses a radio frequency (RF) communication, an infrared communication, a Bluetooth communication, and the like as a wireless communication method, and uses wired communication. As a method, serial communication, power line communication, copper wire communication, etc. supporting RS (Recommended Standard) -232C and RS-485 communication standards are used. Here, power line communication (PLC) is a data communication technology based on CEBus (Consumer Electronics Bus), which is a technology capable of data communication by connecting a communication device to an electrical outlet in a home, usually 50 to 60 Hz. Transmit data using AC frequency.

The power supply unit 214 supplies AC power input to each device to drive the open / close detection unit 212 and the signal transmission unit 214.

The digital door lock 220 includes a signal receiver 221, a key input unit 222, a central processing unit 223, a voice data storage unit 224, a motor driver 225, and a mortise lock 226.

The signal receiver 221 receives a window open / close state signal having a value of '0' or '1' transmitted from the signal transmitter 214 using wired or wireless communication. To this end, the signal receiving unit 221 includes a communication module corresponding to a specific communication method among RF communication, infrared communication, Bluetooth communication, serial communication, power line communication, and copper wire communication available in the signal transmitter 214.

The key input unit 222 is data input means including a plurality of key buttons for inputting key values for setting or unlocking the digital door lock 220. In addition, the key input unit 222 transmits the key value to the central processing unit 223 when the user receives a key value corresponding to the setting of the 'going out lock' function while going out.

The central processing unit 223 reads the voice data stored in the voice data storage unit 2235, the motor driving unit 226, and the speaker according to the digital signal input from the signal receiving unit 221 and the key value input from the key input unit 222. 232 and the beacon 234 are controlled. That is, when it is determined that the signal input from the signal receiving unit 221 is a high signal and a key value corresponding to the setting of the 'going out lock' function is input from the key input unit 222, the central processing unit 224 receives the voice data storage unit ( The alarm voice stored in 225 is read and output through the speaker 232.

On the other hand, when the CPU 224 determines that the signal input from the signal receiving unit 221 is a low signal and a key value corresponding to the setting of the 'going out lock' function is input from the key input unit 222, the motor driving unit 226 The driving control signal is applied to activate the 'going out lock' function of the digital door lock 220 through the motor driving unit 226.

The voice data storage unit 224 stores one or more voice data for alerting the user when the user sets the 'going out lock' function of the digital door lock 220 while the window is open.

When the motor driving unit 225 receives a driving control signal from the central processing unit 223, the motor driving unit 225 drives a motor embedded in the digital door lock 220. In addition, the mortise lock 226 starts or operates according to the driving of the motor driving unit 225 to move or lock the digital door lock 220 by moving a locking device composed of a dead bolt. .

The alarm device 230 may be attached to one side of the digital door lock 220 or installed at a position close to the digital door lock 220 to notify the user by using a voice or a light when the user goes out while the window is open.

The speaker driver 231 receives a speaker driving signal transmitted from the central processing unit 223 of the digital door lock 220 to drive the speaker 232. In addition, the speaker driver 231 transmits the alarm voice data transmitted from the central processing unit 223 to the speaker 232, and the speaker 232 amplifies the input alarm voice data and outputs it to the outside. .

The blinking driver 233 also receives the warning light driving signal transmitted from the central processing unit 223 and performs the function of driving the warning light 234. In addition, the flashing driver 233 is interlocked with the flicker circuit unit 235 for switching the power supplied to the flashing driver 233 at regular time intervals to periodically flash the warning lamp 234. Here, the flicker circuit is a circuit that repeats ON and OFF for a specific time when the input signal is ON, and may separately designate an on time and an off time.

3 is a block diagram schematically showing the configuration of the open / close detection unit 212 according to the type of switch according to the embodiment of the present invention.

FIG. 3A is a view illustrating an open / close detection unit 212 using a NO (not open) switch 310 and an inverter 320, and FIG. 3B is opened and closed using only a NC (not close) switch 330. It is a figure which comprised the detection part 212.

The NO switch 310 shown in FIG. 3A is a switch to which a contact point of a switch is connected when a signal is pressed, and according to an embodiment of the present invention, when the window is closed and the switch is pressed, the NO switch contact is connected to NO. A high signal is output from the switch 310, and when the window is open, the NO switch contact is disconnected, and a low signal is output from the NO switch 310. However, in the exemplary embodiment of the present invention, when the user goes out, the window is opened and the signal output from the NO switch 310 should be reversed. That is, the inverter 320 inverts the output signal output from the NO switch 310 and transmits the signal to the signal transmission unit 214.

On the other hand, the NC switch 330 shown in FIG. 3B is a switch which normally outputs a high signal by connecting the NC switch contact, but when the signal is pressed, the NC switch contact is disconnected to output a low signal. Therefore, according to the exemplary embodiment of the present invention, the NC switch 330 outputs a high signal when the window is open, and when the switch is pressed because the window is closed, the NC switch contact is disconnected to output a low signal. Thus, unlike the NO switch 310 of FIG. 3A, the NC switch 330 does not require a separate inverter device.

4 is a flowchart illustrating an operation process of a digital door lock system for notifying an opening / closing state of a window when a user goes out according to an embodiment of the present invention.

The open / close detection unit 212 of the window monitoring unit 210 continuously detects whether the window is opened or closed and transmits a high signal or a low signal to the signal transmission unit 214 (S400). The signal transmitter 214 transmits the high signal or the low signal received from the open / close detection unit 212 to the digital door lock 220 through a wired or wireless communication as a window open / close signal (S402). Therefore, the digital door lock 220 checks in real time whether the window is opened or closed by using a window open / closed state signal.

Meanwhile, a key value input by the user using the key input unit 222 formed on the outer surface of the digital door lock 220 is input to the central processing unit 223, and the central processing unit 223 inputs the input key value. Analyze (S404). The CPU 223 determines whether the input key value is the 'going out lock' setting signal through the analysis of the input key value in step S404 (S406).

If the determination result of step S406 determines that the input key value is the 'going out lock' setting signal, the central processing unit 223 checks whether the window is opened or closed using the window opening / closing state signal received in step S402 (S408). The CPU 223 determines whether the window is in the open state through the operation in step S408 (S410).

When the CPU 223 determines that the window is open as a result of the determination of step S410, the CPU 223 generates a speaker driving signal and transmits the signal to the speaker driver 231 to drive the speaker 232 (S412). Then, the central processing unit 223 reads out the alarm voice data stored in the voice data storage unit 224 and transmits it to the speaker 232 (S414). The speaker 232 amplifies the received alarm voice data and outputs the sound to the outside (S416).

On the other hand, when the CPU 223 determines that the window is closed as a result of the determination in step S410, the motor driving signal is transmitted to the motor driving unit 225 to set the lock of the door in which the digital door lock 220 is mounted. Drive the motor (S418). The driven motor controls the mortise lock under the control of the central processing unit 223 to lock the door (S420).

Meanwhile, although only a voice alarm message is described as a method of informing that the window is open when the user goes out, the alarm function may also be performed using a flashing light that periodically blinks as described in FIG. 2.

The above description is merely illustrative of the present invention, and those skilled in the art to which the present invention pertains may various modifications without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed herein are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited by these embodiments. It is intended that the scope of the invention be interpreted by the following claims, and that all descriptions within the scope equivalent thereto shall be construed as being included in the scope of the present invention.

As described above, the conventional digital door lock has no special countermeasure against intrusion of outsiders through the window because the door control function is performed only at the entrance door of the door, etc., where the digital door lock is installed. Checking if the window is open has an effect of notifying the user to lock the window through an alarm voice or the like.

Therefore, it is possible to immediately know whether the window is opened or closed when going out, even with a digital door lock installed at the door without installing a separate automatic opening and closing device at the entrance such as a window, thereby reducing costs and effectively preventing illegal intruders. .
