Abstract

PURPOSE:To transmit and dislay a plurality of detection data, by obtaining a synchronizing signal from a commercial power supply. CONSTITUTION:detectros S1-, S4- are connected to terminal controllers A1, A2 respectively. The devices A1, A2 have a synchronizing signal generating section by means of commercial power input synchronism respectively, and data from each detector are time-devided and transmitted to a bus line B. A signal processing interface circuit SI is provided at a device C-3 at control room and also the synchronizing signal generating section by means of the commercial power input synchronism, and the data from the bus line B is given to a microcomputer M while being synchronized with the synchronizing signal to display it on a display CRT.
