Intelligent controller for multifunctional anti-bedsore care bed

Abstract

The invention discloses an intelligent controller for a multifunctional anti-bedsore care bed, which solves the problems of poor safety, high cost, inconvenient operation and the like of the prior control device for an anti-bedsore care bed, and has the advantages of friendly human-machine interface, convenient operation, perfect error protective measures, low manufacturing cost and the like. The structure comprises that a control panel circuit performs liquid crystal display and keystroke operation treatment; a master control board circuit receives an operating command from the control panel circuit through a master control core circuit, and an output drive circuit of the master control board is connected with a relay output board circuit; a signal input circuit detects the bed body position; the relay output board circuit receives a control signal from the output drive circuit to control the motion of a motor; simultaneously, a multi-motor operation detection circuit and a multi-motor fault detection circuit send the detected operation and fault signals to the signal input circuit; and the control panel circuit exchanges information with the master control board circuit through RS485 serial communication to form a master-slave mode control structure.

Description

technical field [0001] The invention relates to a nursing bed control device, in particular to a multifunctional intelligent controller for an anti-bedsore nursing bed. Background technique [0002] The multi-functional anti-decubitus nursing bed is a bed specially designed for paralyzed patients and long-term bedridden patients who cannot take care of themselves. The compression time of the muscles at the compressed part is conducive to blood circulation, ventilation and drying, avoiding the occurrence of pressure ulcers, reducing the pain of patients, and greatly reducing the labor intensity of patient care. In the past, the anti-decubitus nursing bed controller mostly used programmable logic controller (PLC) as the control unit, mainly based on sequence control, lacked fault protection measures, no intuitive display interface, and the cost was high. Contents of the invention [0003] The purpose of the present invention is to solve the problems of poor safety, high cos...
