Abstract
1対の電線を用いて複数の正確なアナログ信号とデジタル信号を時分割で伝送できる装置を供給する。
【解決手段】
親装置1に複数の端末装置3を接続して端末のアナログ電圧を計測するもので親装置1が供給するクロックの隙間にクロックとは逆極性の電圧で基準電圧6と計測電圧7を順次切り替えて接続する。これにより端末装置3の基準電圧6と計測電圧7がダイレクトに接続される。この仕組みにより多点のアナログ計測信号の測定が1対の電線で可能になるもので計測電圧7の伝送路2による電圧降下による誤差はあらかじめ電圧の分かっている基準電圧6の計測により補正されて正確なアナログ計測ができるものである。また一定の計測電圧7と基準電圧6のON/OFFを端末装置側の接点信号で行うことによりアナログ信号と接点や積算値のデジタル信号を混在して伝送できるものである。
