来る判別回路を設け、前記停電信号−と、優先割込信萼
とを区別することを特徴とする優先伝送方式。In a remote monitoring device in which a master station and a slave station are connected by wire, an oscillator that transmits a power outage signal of the slave station and an oscillator that transmits a power outage signal of the slave station, using the same line as the remote monitoring day and night, and a first interrupt transmission of the master station. An oscillation circuit that also serves as an oscillator and can classify the transmission pattern of the oscillator into two ways, and a discrimination circuit that can receive and classify the two ways are provided to distinguish between the power outage signal and the priority interrupt signal. A priority transmission method featuring:
