When a situation occurs in the detector 1 connected to the outside, the detector interface unit 102 connecting the corresponding signal, and the detector controller 120 for controlling the detector 1 when the detector 1 is released, returned, or stopped. ), A key input unit 122 for manipulating a call and a main body, a display unit 112 for viewing a visitor image when calling from a door lobby phone (or door phone) 4, a visitor check and a call control situation Voice processing unit 114 for transmitting voice messages when they occur, guard room call path selection unit 124 for controlling voice coming from the guard room, storage unit 106 for storing individual IDs for a plurality of extension phones, and entrance doors. It consists of a wireless communication unit 110 for transmitting the video and audio coming from the phone (or lobby phone) 4 through the wireless communication to the expansion phone 1-expansion phone n (300, 400).

The wireless communication unit 110 may use various wireless communication technologies capable of transmitting data and voice. The wireless communication technology may be Bluetooth, HomeRF, SWAP, TDMA, DECT, WLAN technology.

Bluetooth is a wireless communication technology that wirelessly connects various digital home appliances as well as information and communication devices such as computers, printers, mobile phones, and PDAs in homes and offices. It consists of an asynchronous data transmission channel and a three-channel synchronous data transmission channel using a radio frequency in the 2.4 GHz Industrial Scientific Medical (ISM) band.

HomeRF (Home Radio Frequency) / SWAP (Shared Wireless Access Protocol) uses 2.4GHz ISM bandwidth as a standard 2.4GHz wireless technology for the transmission of voice and data traffic and the public network and the Internet.

Time division multiple access (TDMA) and digital codeless telecommunication (DECT) technologies enable voice, data traffic transmission, and interworking with the PSTN and the Internet.

Wireless LAN / IEEE 802.11, IEEE802.11b is a method of transmitting data between the LAN-based network and the terminal using the 2.4GHz band radio frequency.

Accordingly, it can be usefully used in places or departments and mobile work that is difficult to build a wired network.

4 is a block diagram illustrating an extension phone for performing wireless communication according to the present invention.

Referring to FIG. 4, the extension phone includes a wireless communication unit 202 for performing wireless communication with the home automation device 100, a controller 204 for controlling the overall operation of the extension phone, a program for operating the extension phone, and A storage unit 206 for storing individual IDs for secure communication, a key input unit 208 for manipulating a home automated call and a main body, and a voice processing unit 210 for controlling visitor confirmation and calls and transmitting a voice message when a situation occurs. And, the display unit 212, the microphone 214, the speaker 216 to perform a wireless communication with the home automation device 100 to view the visitor image when calling from the door phone (or door phone) 4 It is configured to include.

When calling from the door phone 4 in the home network system configured as described above looks at the procedure for transmitting a signal to the expansion phone 1 (200)-expansion phone n (300) through the wireless communication unit (110).

When the door door phone 4 is called, the control unit 104 detects the first through the door phone call control, and the visitor image is displayed on the display unit 112 while the melody is transmitted through the voice processing unit 114 and the speaker 116.

Meanwhile, the wireless communication unit 110 receiving the video and audio signals converts an analog signal into a digital signal and wirelessly transmits the analog signal to the expansion phone 1 200 and the expansion phone n 300 through a transmission antenna.

The expansion phone 1 200 or the expansion phone n 300 receiving the wireless signal from the home automation device 200 converts the digital signal into an analog signal through the wireless communication unit 202 and rings the call at the same time.

At this time, when the user presses a call button in the key input unit 208 of the extension phone 1 200 that the user wants to talk with, the control unit 204 reads its own extension phone ID stored in the storage unit 206 and the wireless communication unit 202. Send a call connection request while transmitting to the home automation device 100 through. The control unit 104 of the home automation device 100 detects the ID of the extension phone transmitted from the expansion phone 1 200 through the wireless communication unit 110 and performs call connection if the ID of the extension phone is called. Send an image to the phone 1 (200). Accordingly, the front door phone 4 and the expansion phone 1 200 are connected. At this time, the image is unidirectional, and voice and data are bidirectionally communicated.

Meanwhile, a description will be given of a method of transmitting a signal to the expansion phone 1 200 and the expansion phone n 300 through wireless communication of the home automation device 100 when a situation occurs in the plurality of detectors 1, 2, 3.

When a situation occurs in the crime prevention (1), fire (2), gas detector (3) is transmitted to the control unit 104 through the detector interface unit 102 to separate the corresponding data to the corresponding alarm through the voice processing unit 114 Ringing to the speaker 116, and simultaneously converting an analog signal into a digital signal through a 2.4 GHz radio frequency through the wireless communication unit 110 to the expansion phone 1 (200) and the expansion phone n (300) wirelessly through a transmission antenna. send.

The alarm stop return is an alarm stop return if any one of the key input unit 122 of the home automation device 100 and the key buttons of the expansion phone 1 200 and the expansion phone n 300 are input.

Next, an ID input method for preventing radio interference will be described.

In the ID input method, when a user operates the key input unit 122 of the home automation device 100 and inputs the ID, the ID of the frequency to be used is transferred to the storage unit 106 through the input / output expansion port 108. Stored. At this time, up to 65,000 IDs for preventing interference can be input.

Therefore, since an arbitrary ID can be assigned to the extension phone for each generation, it is possible to solve the security problem of wireless communication for each generation.

In addition, although not described in an embodiment, a WEP (Wired Equipment Privacy) technology may be used for security between the home automation device 100, the expansion phone 1 200, and the expansion phone n 200. WEP can use the RC4 algorithm and 40bit encryption key (128bit can be used) as a transmission data encryption method between WLAN card and AP defined in IEEE802.b.

According to the present invention, when a wireless modem is used in a conventional home automation system main body, the installation is simple, and when an additional phone is installed as an extension phone at a site where only a conventional home automation system main body is sold, there is an expansion sales effect.

For example, the conventional wired method is time-consuming and expensive to install, but the present invention enables easy installation. In addition, in the conventional wired system, wiring is necessary, but according to the present invention, wiring is unnecessary. Accordingly, the wired system of the related art inevitably requires rework of the wiring at the time of expansion, but according to the present invention, it is possible to quickly build a network.

In addition, the conventional wired system has difficulty in maintenance, but according to the present invention, the maintenance is simplified. In addition, the conventional wired method is not mobile, but according to the present invention it is possible to install a mobile phone expansion.
