Abstract

The present invention relates to a digital door, and more particularly, to a digital door which is capable of improving security and convenience using network environments, improving safety in an emergency such as a fire, and improving aesthetic and functionality of a door. The digital door includes: a power supply unit that supplies power to the door; an input unit that that mechanically or electromagnetically receives an input signal from a user and converts the received input signal into digital data; a multi-lock unit that has a multi-locking system constituted by a plurality of locks and locks/unlocks the door; a communication unit that connects the door with a network; a memory unit that stores a control program and related data, fire and security-related messages, image and voice data inputted from the input unit; an audio unit that generates an alarm sound according to the messages; and a controller that is connected to the power supply unit, the multi-lock unit, the communication unit, the memory unit and the audio unit for controlling the digital door.

Claims

1. A digital door comprising:

a power supply unit that supplies power to the door;

an input unit that that mechanically or electromagnetically receives an input signal from a user and converts the received input signal into digital data;

a multi-lock unit that has a multi-locking system constituted by a plurality of locks and locks/unlocks the door;

a communication unit that connects the door with a network;

a memory unit that stores a control program and related data, fire and security-related messages, image and voice data inputted from the input unit;

an audio unit that generates an alarm sound according to the messages; and

a controller that is connected to the power supply unit, the multi-lock unit, the communication unit, the memory unit and the audio unit for controlling the digital door.

2. The digital door of claim 1, wherein the input unit includes an interphone that shows a user an image of a visitor and allows the user to have a conversation with the visitor, and a camera unit for monitor of the visitor and video communication with the visitor.

3. The digital door of claim 1, further comprising:

a smoke and fire detecting unit that detects smoke and fire, generates an analog signal related to the detected smoke and fire, and converts the generated analog signal into digital data; and

an abnormality detecting unit that detects abnormality of the multi-lock unit and the input unit, which may occur due to unauthorized access from the outside.

4. The digital door of claim 1, wherein the communication unit includes a communication module to access a wireless network or access a home network interlocking with Internet by being connected to a home terminal apparatus for communication between a mobile terminal and the door.

5. The digital door of claim 4, wherein the controller communicates with an external user terminal through the communication unit to perform a notification function and a door opening/closing operation.

6. The digital door of claim 1, further comprising a door closer unit that automatically closes an opened door in order to prevent fire and smoke from spreading over.

7. The digital door of claim 1, further comprising an anion ventilating unit that ventilates indoor air in a space in which the digital door is installed.

8. The digital door of claim 1, wherein the controller controls the multi-lock unit to be opened/closed in multi-step according to a domino fashion that the locks in the multi-lock unit operate sequentially in a preset sequence.

9. The digital door of claim 8, wherein the power supply unit, the input unit, the multi-lock unit, the communication unit, the memory unit, the audio unit, the controller, the smoke and fire detecting unit, the abnormality detecting unit, the door closer unit and the anion ventilating unit are formed on one side of the door, the digital door further comprising a casing frame that covers and protects the power supply unit, the input unit, the multi-lock unit, the communication unit, the memory unit, the audio unit, the controller, the smoke and fire detecting unit, the abnormality detecting unit, the door closer unit and the anion ventilating unit, wherein the door is moduled into a body including the components of the door and the casing frame.

10. A digital door comprising:

a multi-lock unit that has a multi-locking system constituted by a plurality of locks and locks/unlocks the door; and

a controller that controls the multi-lock unit,

wherein a key is installed at each of covers of the plurality of locks and the door is opened/closed by rotating the key.

11. The digital door of claim 10, further comprising:

a first gear that engages with the key; and

a second gear that is formed at one side of a motor to drive the locks,

wherein the door is opened/closed by moving the locks connected to the motor as the first gear engages with the second gear in interlocking therebetween when the key is rotated.

12. The digital door of claim 11, wherein a projection that engages with a groove of the locks is formed at one side of the first gear, and the door is opened/closed by moving a dead ball while the first gear is rotated in interlocking with the second gear as the second gear is rotated.

13. The digital door of claim 10, wherein the controller controls the multi-lock unit to be opened/closed in multi-step according to a domino fashion that the locks in the multi-lock unit operate sequentially in a preset sequence.

14-15. -15. (canceled)

16. A digital door comprising:

a smoke and fire detecting unit that is formed at one side of the door, detects smoke and fire, generates an analog signal related to the detected smoke and fire, and converts the generated analog signal into digital data; and

a door closer unit that is electromagnetically coupled with the smoke and fire detecting unit, is installed at a predetermined position at which the door is moved, and fixes the door,

wherein, according to user'"'"'s intention, the smoke and fire detecting unit is adhered to the door closer unit by an attractive force at ordinary times such that the smoke and fire detecting unit is fixed at the predetermined position, while, at smoke and fire, the smoke and fire detecting unit is supplied with power and the door closer unit secedes from the predetermined position by a repulsive force between the smoke and fire detecting unit and the door closer unit, so that the door is automatically closed.

17. The digital door of claim 16, wherein the door closer unit includes a neodymium magnet unit that is electromagnetically coupled with the smoke and fire detecting unit, and a holder that supports the neodymium magnet unit and fixes the neodymium magnet unit at the predetermined position.

18. The digital door of claim 17, wherein the neodymium magnet unit includes a front rubber packing having a cushion to absorb impact when the neodymium magnet is combined to the door, a neodymium magnet that is electromagnetically coupled with the smoke and fire detecting unit, and a spring as a buffer that supports the neodymium magnet and absorbs impact at collision with the door.
