PURPOSE:To enable various information to be transmitted with double core cable by a method wherein a transmitter and a receiver having the same constitution and a micro-computer, respectively, are arranged the combustion safety device and the remote controller and then the time-series digital signals are transmitted alternatively under a time sharing. CONSTITUTION:When one of transmitter and receiver units 4 is in a transmitting condition, the other transmitter and receiver unit 5 performs only the receiving action. When the transmitter and receiver unit 5 confirms that the correct data are received, the transmitter and receiver unit 5 performs the transmitting operation and the other transmitter and receiver unit 4 performs only the receiving action. Alternative transmitting of the data under a time sharing operation may assure only two core cables in the cable 3. Further, employing of a protocol in which the flow of signal processing is determined with the time of the clock signal in both micro-computers 13 eliminates any complex receiving of the synchronized signals and thus it is possible to simplify the constitution of the signal transmitting device itself. |
