Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

전원선을 통해 정보를 동시에 송수신하는 장치.Device that simultaneously sends and receives information through the power line.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

전화선을 통한 정보의 전달은 전화선이 연결된 구역에서만이 사용 가능하였으며, 송수신장치의 위치가 변경될 때 마다 전화선을 다시 설치하여야 했다. 또한 전원선을 이용하는 인터콤의 경우에는 단방향 통화로 양방향 동시 통화가 불가능하여 정확한 정보 전달이 이루어지지 않았다.The transmission of information via the telephone line was only available in the area where the telephone line was connected, and the telephone line had to be re-installed whenever the position of the transceiver was changed. In addition, in the case of the intercom using the power line, the two-way simultaneous call was not possible with a one-way call, and thus accurate information was not delivered.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

전화회로와 인터콤을 포함한 정보전송매체에 전원선을 통해 입력되는 전원신호에 정보를 믹싱하거나 검출하는 매칭부와, 송신모드와 수신모드를 자동으로 전환하여 동시에 송, 수신이 수행되도록 2선과 4선을 변환하는 하이브리드회로와, 전화선을 통해 입, 출력되는 정보를 상기 하이브리드회로측으로 전송하는 드라이브회로와, 상기 전원선과 매칭부 사이에 연결되어 신호를 양방향 전송하는 트랜스입출력회로로 구성되어 전원선으로 정보를 양방향 전송하는 장치.Matching unit that mixes or detects information on power signal input through power line to information transmission medium including telephone circuit and intercom, and 2-wire and 4-wire so that transmission and reception can be performed simultaneously by automatically switching between transmission mode and reception mode. And a hybrid circuit for converting a circuit, a drive circuit for transmitting information input and output through a telephone line to the hybrid circuit side, and a trans input / output circuit connected between the power supply line and a matching unit and transmitting signals bidirectionally. Device for bidirectional transmission.

4. 발명의 중요한 용도4. Important uses of the invention
