A Transmission Control System's Research for a Nursing Bed with Four Transmissions Driven by a Single Motor
This paper introduces a kind of multi-function nursing bed control system which has won Chinese invention patent. This system takes AT89C51 as a core, uses a unique control mode for a single electrical machinery driven four transmissions, and adopts a modular control technology which respectively controls the movements of four lead screws through electrical machinery’s positive or negative rotation, and electromagnetic clutch’s connection or disconnection to decide the power transmission direction, so as to realize the different postures of the nursing bed, and meet the demands of patient care.
