PARAMETER-TO-CODE CONVERTER Russian patent published in 2002 - IPC

Abstract RU 2193794 C2

FIELD: automatic control; digital control systems. SUBSTANCE: proposed converter relates to digital control systems requiring signals in the form of digital codes to function as setting and feedback signals and using setting devices and feedback sensors with output parameters shaped in the form of ac voltage whose amplitude is a function of parameter being measured. It has series- connected pulse generator, power unit, sensor with varying output- voltage amplitude, and first comparator; pulse generator output is also connected to complementing input of time-interval meter where digital code is built up across its output; novelty is introduction of second comparator and AND circuit; power unit output is connected to second input of first comparator; outputs of first and second comparators are connected to first and second inputs of AND circuit whose output is connected to enable input of time-interval meter. EFFECT: simplified design of converter. 2 dwg
