Abstract

본 발명은 홈오토메이션의 다중 통화 장치에 관한 것으로, 종래에는 도어 폰이나 경비실중 한쪽과 통화가 이루어진 상태에서 호출에 의한 다른 쪽과 통화를 원할 경우에는 반드시 현 통화로를 끊고 다시 통화로를 연결하여야 함으로 3자 통화 또는 교차 통화가 불가능한 문제점이 있었다. 이러한 문제점을 개선하기 위하여 본 발명은 통화 형태에 따라 통화 경로를 형성하도록 회로를 구현하고 휴대폰과 무선 통화를 가능하게 하는 회로를 구현한 것으로, 본 발명은 통화 형태에 따라 다양한 통화 경로를 형성함으로써 3자 통화는 물론 교차 통화를 가능하게 하여 사용자에게 편리함을 제공할 수 있다.The present invention relates to a home automation multi-calling device, and in the related art, when a call is made with one of a door phone or a security room and a call is made with the other, a current call must be disconnected and the call is connected again. As a result, there was a problem that a three-way call or a cross call was impossible. In order to solve this problem, the present invention implements a circuit to form a call path according to a call type and implements a circuit that enables wireless communication with a mobile phone. Not only the party call but also the cross call can be provided to provide convenience to the user.
