KR960020298A - Interphone device of home automation (HA) system and household calling method using the device - Google Patents

Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home automation (HA) system, and in particular, an interphone device of a home automation system and a generation using the device that enable direct call between generations by allowing centralized management of serial data communication, analysis, and call paths. How to call the liver.

In the conventional home automation system, if a first household needs to call another household, the household must be switched to the household through the guard room. Therefore, when the guard is absent, there is a problem that other households cannot be called.

Therefore, the present invention controls the communication unit by analyzing the data output from the first data transceiver and the first data transceiver and the first data transceiver to recover and output the weak data signal transmitted during data communication with the guard room, A generation terminal comprising a first central processing unit for recognizing a signal through a keypad and generating a DTMF signal corresponding to a corresponding number; and a DTMF tone generating unit for generating a corresponding DTMF tone under control of the first central processing unit; A second data transceiver for transmitting and receiving data to and from the first data transceiver and the second data transceiver to retrieve a generation unique number of each household and to control a call path, and through a DTMF tone receiver; It is equipped with an interphone unit consisting of a central processing unit for retrieving the DTMF tones received to determine the generation to call When the household call button is pressed, the first step of comparing the polling data in the guard room and the household unique number, and if the polling data and the household unique number are integrated, switch the transmission mode and wait until the signal transmitted from the guard room arrives. And a second step of calling a household by pressing a household number when the household dispatch preparation completion signal arrives from the security guard, and converting the called household number into a household code corresponding to the household code. A fourth step of polling a household; a fifth step of connecting a communication path between generations when the polled generation arrives; and a sixth step of turning off the connected communication path and switching to a standby mode when a call termination signal is received; By sequentially executing the above problem of the conventional home automation system was solved.

Claims (4)

Improves the data level transmitted during the data communication with the security office, and analyzes the first data transceiver for recovering the weak data signal received and outputs the data from the first data transceiver and controls the call unit, and the signal through the keypad. A generation terminal comprising a first central processing unit for recognizing a signal and generating a DTMF signal corresponding to a corresponding number, and a DTMF tone generating unit for generating a corresponding DTMF tone under control of the first central processing unit, and the generation terminal DTMF tones received through the DTMF tone receiving unit while controlling the call path by retrieving the generation unique number of each generation through the second data transmitting and receiving unit and the second data transmitting and receiving unit for transmitting and receiving data with the first data transmitting and receiving unit therein. Characterized in that the interphone unit consisting of a central processing unit for determining the generation to call by searching for Intercom devices for home automation system. The interphone device of claim 1, wherein the generation terminal further comprises a generation call button for generation call and a generation code number setting switch for setting generation code number. 3. The interphone device of claim 2, wherein the generation code number setting switch is a binary switch. When the household call button is pressed, the first step of comparing the polling data in the guard room with the household unique number; and when the polling data and the household unique number match, switching to the transmission mode and waiting for a signal from the guard room to arrive. Step 2, a third step of calling a household by pressing a household number when a generation call ready signal arrives from the guard room; converting the called household number into a corresponding household code, and converting the household with the converted household code. A fourth step of polling; a fifth step of connecting the inter-generational call paths when the polled generation arrives; and a sixth step of turning off the connected call paths and switching to a standby mode when a call termination signal is received; Generation call method using the interphone device of the home automation system characterized in that. ※ Note: The disclosure is based on the initial application.
