SIGNAL TRANSMISSION SYSTEM FROM SENSORS WITH ANALOGUE OUTPUT FOR THE TWO-WIRELESS COMMUNICATION LINE Russian patent published in 2018 - IPC G08C19/02 

FIELD: data processing.

SUBSTANCE: invention relates to signaling devices. For this purpose, a signal transmission system is proposed; it comprises a sensor with an analog output, which output is connected to an input of an impedance element, whose output is connected to the sensor supply terminal, the ends of the wires of the two-wire communication line are connected to the first and second contacts of the receiving unit that contains a current collector resistor, as well as a constant voltage source, whose negative bus is the common bus of the receiving node, and the first end of the second wire of the two-wire communication line is connected to the common terminal of the sensor, receiving unit comprises a current collector amplifier whose inputs are connected to the first and second terminals of the current collector resistor which are connected respectively to the positive bus of the constant voltage source and the first contact of the receiving unit whose second contact is connected to the common bus, output of the current collector amplifier is the signal output, and the sensor power output is connected to the output of the voltage regulator, the common output and input of which are connected to the common output of the sensor and the first end of the first wire.

EFFECT: increased reliability, expanded scope of use and fail-free operation.
