The apparatus for making a phone call is a well-known technique and is not a main component for describing the present invention, and thus a detailed description thereof will be omitted.

As shown in FIG. 4, the door phone 510 transmits / receives a control signal with a wall signal controller 410 for controlling the entire door phone, a digital signal processor for transmitting and receiving sound and an image with a wall pad, and a wall pad. A communication unit 420 to receive driving power from a commercial power source, a power unit for converting into a predetermined DC voltage, a storage unit 411 for storing door phone setting information, and installed outside the front door to input a user's touch input signal. A touch panel unit 462 for receiving, a display unit 461 for displaying an image, a video processor unit 460 for processing an image signal, and a memory for temporarily storing setting information or a video signal of the video processor unit 460 Part 463, the locking unit 430 to open or close the front door, the door handle 440 is installed on the interior side of the front door to drive the locking unit by the user's operation, A switch unit 441 installed at one side of the door handle unit or installed at one side of the door handle unit, a sensor unit 451 installed at one side of the outdoor side of the front door to recognize an approach of an object, and the other of the outdoor side of the front door. The camera unit 452 is installed at one side and is configured to include an RF card reader 453 configured to release the locking of the locking unit with respect to an RF card of a pre-registered number.

The operation principle of the door phone system according to the present invention having the above configuration will be described in detail below.

First, the operation of the door phone system when the user moves from the outdoor to the indoor will open the door by releasing the locked locking unit 430 when the user moves from the outdoor to the indoor.

Methods of unlocking the locking unit 430 include a method of inputting a password, a method of using a pre-registered RF card, or a method of face recognition or iris recognition of the camera unit 452.

Since a method of recognizing a face or an iris by a camera is well known in the art, detailed description thereof will be omitted. In addition, since the method using the RF card is also known technology, the detailed description thereof will be omitted.

In order to release the locking state of the locking unit 430 by inputting a password in the door phone system according to the present invention, the display unit 461 outputs a so-called 10-key type number button as shown in FIG. 9. When the user presses the numeric buttons displayed on the display 461 and inputs them in the order of preset numbers, the touch panel unit 462 measures the touched position by the user and transmits the touched position to the door phone controller 410.

The door phone controller 410 compares the position of the numeric button displayed on the display 461 with the touch position recognized by the touch panel, maps the touch position to the numeric button, and maps the sequence of the mapped numeric number to a preset password. If it is matched, the lock driving unit 431 is driven to release the lock state of the locking unit 430, and if it does not match, the password that does not match the preset password is input to the wall pad 400 '. The camera transmits a signal and simultaneously drives the camera unit 452 to capture the outdoor situation of the front door, and the captured image is processed by the video processor 460 to be delivered to the door phone controller 410, and again the wall pad 400. ') Is transmitted through the image and audio signal lines and output to the sound output unit 531 and the image output unit 532 of the wall pad 400'.

When the number of heat or light is changed by the detection sensor unit 451, for example, an IR sensor or an optical sensor, as a method of activating a number button to be displayed on the display unit 461, it is transmitted to the control unit 410 to the door phone. When the door phone controller 410 recognizes that the user has approached, the door phone controller 410 drives the display 461 to display the numeric buttons.

At this time, the numeric button is changed every time the position is driven by the value output by the random function generator, not the fixed position. That is, as shown in FIG. 9, the random function generator is initially displayed in the position as shown in FIG. 9 (a) as in the case of a normal 10key, but in the next drive, it is normally shown in FIGS. 9 (b) and 9 (c). Is displayed in a completely different position from that of the 10key number button. As described above, since the number button for inputting a password is changed every time the driver does not leave a fingerprint at a fixed location, it is impossible for an outsider to find a password by collecting a fingerprint.

The random function generator is stored in the memory unit 463 included in the video processor unit 460, and is read out by the video processor unit 460 whenever the number button is displayed on the display unit 461. This will change the array of.

On the other hand, the arrangement information of the number buttons, that is, the position information of each number in the display unit 461 is transmitted to the door phone controller 410 and stored in the storage unit 411 to be touched when a touch of the number button is input by the user. The touched number is recognized by comparing with the position information recognized by the panel.

The operation of the switch unit 441 that is a dual locking device in the door phone 400 will be described. In general, the front door is locked by the locking unit 430 is inserted into the groove which is perforated in the front door frame, the locking unit 430 when attempting to unlock the locking unit 430 illegally from the outside with a key The double locking device is further provided so that the locked state of the) is not released.

However, when the emergency situation occurs in the state of setting the double lock as described above, if the user does not recognize that the double lock is set by turning the door handle 440 to release the locking state of the locking unit 430 Even if the locking device 430 is not driven by the dual locking device, the user can panic in an emergency situation.

However, the dual locking device of the present invention further includes a button-type switch 441 on one side of the door handle to release the lock when the door handle is operated, so that the locking jaw is relaxed when the door handle is operated. To be automatically released.

On the other hand, the switch unit 441 is electrically connected to the door phone control unit 410 when the lock is set to the occupancy mode, when the lock is to go out mode.

That is, when the switch unit 441 is in the first position, when the switch unit 441 is measured by a sensor for measuring the position and transmitted to the door phone control unit 410, the door phone control unit 410 is a door phone system and a locking driving unit 431. ) To enter the room mode. On the other hand, when the switch unit 441 is in the second position, the sensor is measured by a position measuring sensor and transmitted to the door phone control unit 410, the door phone control unit 410 is a door phone system and the locking drive unit 431 To control the outing mode.

In the occupancy mode, the switch unit 441 is operated only by the operation of the door handle unit 440, and the door is not opened even when the lock state of the locking unit 430 is released and the user does not open the door in an emergency. A double lock is set at the same time to prevent falling into a state.

In the outing mode, the double lock is not set, and thus the door is opened when the locking state of the locking unit 430 is released. 8 is an example of door phone mode setting according to the state of the switch unit 441.

In the above description, the door phone system is set to the outing mode and the occupancy mode according to the position of the switch unit 441, that is, the occupancy mode in the first position and the outgoing mode in the second position. It is also possible by the menu displayed on the display 461 in a way to set to this will be described in detail below.

On the other hand, the door phone control unit 410 transmits it to the wall pad control unit 530 when it is set to go out mode, the wall pad control unit 530 to the elevator to move the elevator 540 on the floor to the elevator management unit 534 It transmits a drive signal and outputs a signal to cut off the power supply to the power supply 550 except for the device that is essential to the power management unit 535 to prevent unnecessary waste of power.

For example, in the case of a living room light, a bathroom light, or a TV, it is preferable to cut off the power supply because the user does not need to be driven when the user goes out. The connected power of the TV may designate a specific power terminal as a TV power terminal in advance to cut off a power line for supplying power to the corresponding power terminal by a breaker.

In addition, the driving signal is transmitted to the gas valve driving unit 536 so that the gas valve 560 is blocked, thereby preventing the gas from leaking out and causing a fire.

However, it is necessary to drive the living room light or the TV even when the user goes out. To this end, the user moves the power manager 535 through the display mode setting menu through the display unit 461 and the touch panel unit 462 outside the door phone. Can be set arbitrarily.

For example, when the user goes out for a long time, it is necessary to externally recognize that there is a person indoors by turning on a living room light or making a TV sound.

To this end, when the user opens the door and is outdoors, the detection sensor unit 451 detects a change in heat or light quantity and the detected sensor signal is transmitted to the door phone controller 410 and the video phone unit of the door phone controller 410. The menu 460 is driven to display a predetermined menu on the display unit 461.

Among the predetermined menus, a call button menu is displayed on one side of the display unit 461, and when the user touches the position where the call button menu is displayed for more than a predetermined time, the door phone controller 410. Recognizing this as the outgoing mode setting, the video processor unit 460 drives the predetermined menu for the outgoing mode setting to be displayed on the display unit 461.

That is, the display unit 461 displays a power setting item, and each item displays a name of the corresponding device and an ON / OFF setting item so that the user can set the power ON / OFF for each corresponding device.

The display unit 461 may store display information in the memory unit 463 so that appropriate information is displayed according to a corresponding menu. For example, when the door phone is not used, the lake, the resident's name, and the authentication of the furniture are completed. The text previously input by the user may be displayed as the authentication completion message.

6 is a flowchart illustrating a method for controlling a door phone system according to the present invention.

When a change in heat or light amount is detected by a sensor in a state in which the door phone system is driven according to the present invention (S610), the door phone control unit drives the camera to transfer the captured image information to the wall pad (S611).

Subsequently, the display unit displays lake information such as a house, a house, and a resident's name of the furniture (S612). The lake information may be such that the door phone is driven and displayed continuously, but only the display grows after a certain time after the driving of the door phone is stopped.

After that, if the user is not a resident, the display unit which wants to talk with the user inside is displayed with a predetermined menu including a call button, and when the user touches the touch panel unit corresponding to the position where the call button is displayed, the call button function is performed. In this case, it is determined whether the touch panel unit is touched for less than a predetermined time or more than a predetermined time (S621).

If it is touched within a predetermined time it is determined that the household call (S630), and the household residents communicate with the wall pad through the wall pad, and the household occupant delivers a signal for opening the door to the door phone through the door phone control unit through the door phone control unit Driving to release the locking state of the locking unit (S660).

When the microphone and the speaker are driven to talk to the residents of the household and the householder operates the door opening through the wall pad, the locking unit and the switch unit are driven to release the double lock and the door locking. On the other hand, when the call button is driven, it may stop transmitting the camera image to the wall pad (S624).

Meanwhile, when the call button is touched for a predetermined time or longer, it is determined that the user is out. The door phone controller displays an authentication menu to check whether the user is a legitimate user by driving the video processor (S630). In response to the authentication menu displayed on the display unit, the user touches and inputs authentication data at a corresponding position of the touch panel unit, and when the authentication is approved, the outing mode setting menu is displayed (S631). If authentication fails, the data is displayed on the display unit that it is not authenticated (S631).

Touching the power setting menu of the outing mode setting menu, the user can arbitrarily set the power supply for the home power supply (S632), the power supply to the power supply is controlled when the power setting for the outing mode and the power supply is completed. , The gas valve is blocked and the elevator is called (S633).

Another way of opening the door is to drive the call button, not by the generation call, but by authentication.

Specifically, when the user selects an authentication menu other than a call button menu among menus displayed on the display unit (S622), the display unit displays 10keys on the display unit in a random manner to input authentication data, and the user displays the display on the touch panel unit. If authentication data is input by touching a location corresponding to 10key displayed on the input unit and the input data does not match the authentication data stored in the storage unit (S623), authentication has failed in the display unit and the image output unit of the wall pad. The information displayed is output (S641), a warning message is output through the speaker of the door phone, and the image photographed by the camera may be stored in the door phone storage unit under the control of the door phone controller (S640).

Meanwhile, if the authentication is approved (S623), the lock state of the locking unit is released (S660), and authentication data is transmitted to the wall pad (S651), and information indicating that authentication is successful is displayed (S650), and the door phone controller controls the door phone. Set it to the in-room mode and operate the switch to activate the anti-panic and double lock functions.

7 is a procedure of controlling the indoor power, gas valve and elevator according to the outgoing mode setting in the door phone system according to the present invention.
