PURPOSE:To simplify a system constitution and to enlarge the redundancy by counting a signal from a central control unit in a terminal equipment, generating sensor address signal data and transmitting the data from the corresponding sensor to the central control unit. CONSTITUTION:In response to the start pulse from a start pulse generating part SP, the transmitting-receiving part SP of the central control unit 1 transmits a signal for determining the sensor address supplied from a system control part SC to a transmission path L. The counter CT of a terminal equipment 2 counts the signal for determining the sensor address transmitted from a transmitting-receiving part SR, generates the sensor address signal data, supplies to the transmitting-receiving part RS and a multiplexer MPX supplies a converting starting signal to an A/D converter AD, and supplies the transmission starting signal to the transmitting-receiving part RS. The multiplexer MPX supplies the data from the sensor S of the corresponding address to an A/D converter AD, and the transmitting-receiving part RS transmits the data from the sensor S and the sensor address signal data to the transmitting-receiving part SR.
