Abstract

본 발명은 BA(building dutomation)동에 사용되는 전력패널의 감시 및 제어시스템에 관한 것으로서, 전력패널의 각 관제점에서의 트랜스듀스들과 제어페널간을 직접연결 배선하지 않고, 전력패널내에 TMB(transducermultiplex board)를 구비하여 트랜스 듀스와 제어패널간의 신호전송을 TMB를 통해서 디지탈상태로 이루어지도록 하므로서 전력패널과 제어패널간에는 관제점의 수와 관계없이 TMB와 제어패널간을 연결하는 실드된 2가닥의 꼬임선만ㄴ을 구비한 전력패널 감시 및 제어시스템을 제공한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for monitoring and controlling a power panel used in building dutomation (BA) buildings. It is equipped with a transducer multiplex board so that the signal transmission between the transducer and the control panel can be made digitally through the TMB. Provides power panel monitoring and control system with twisted line only.
