DAISY CHAIN TWO-WIRE SENSOR MEASURING SYSTEM AND METHOD Russian patent published in 2022 - IPC G01K7/16 H04B3/54 H04L12/40 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the field of communication technologies. The system contains: one or more slave modules, the main module and a daisy chain connection wire. The slave module is connected to one or more sensors and is designed to modulate the detected sensor signal into the corresponding current signal. The main module is cascaded in series with the first slave module, the slave module of the upper stage and the slave module of the lower stage in one or more slave modules by means of a daisy chain connection wire to form a daisy chain sensor network and is connected to the upper computer by means of a communication wire. The wire of the daisy chain connection is designed to supply power and transmit the current signal received by the slave module using modulation, so that the main module receives and then decodes the current signal in the wire of the daisy chain connection to obtain the corresponding sensor data.

EFFECT: simplifying the connection of modules, increasing control efficiency and protection against interference during signal transmission.
