KR960032927A - Home Automation (HA) Data Transmission Device - Google Patents

Abstract

The present invention relates to a data wireless transmission apparatus for home automation.

In the conventional HA data transmission device, data lines, audio lines, and video lines are wired in the walls of an apartment to transfer data. Therefore, the product cannot be changed in an apartment where wiring is completed. If a short is generated, the wall must be broken for recovery, and the number of strands of wiring increases to increase the voice signal connection path.

Therefore, the present invention is to improve the above problems of the prior art, regardless of the piping and wiring installed in the existing apartments, such as by transmitting and receiving each data, such as wirelessly between each generation, management equipment and common entrance system system, It is to eliminate the limitations and problems of functional implementation by piping.
