Title:
CONTROL/MONITORING SIGNAL TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/058412
Kind Code:
A1
Abstract:
The present invention comprises: a control unit; a master station that performs data transmission/reception; and a plurality of slave stations that perform, according to a transmission synchronization scheme, data transmission/reception with the master station via a common transmission line. The slave stations superimpose, onto a power source voltage area of a transmission signal formed by connecting a plurality of power source voltage level pulse signals, a single current signal for which a prescribed level is maintained for a prescribed time with a current value allocated from a plurality of predetermined weightings representing a plurality of preset channels. The master station uses, as a reference value, the current value of the power source voltage area of an address-less region which has not been allocated for the transmission/reception of data in the transmission signal, and on the basis of the weightings and the difference between the current value of the current signal and the reference value, extracts, for each of the plurality of channels, a plurality of data pieces output to the same area of the transmission signal. The reference value is updated every time there is a transmission involving the address-less region.
