A synchronization system and synchronization method for realizing synchronous lifting of the backboard of the nursing bed and the backboard of an intelligent wheelchair in a robot nursing bed

Abstract

The invention relates to a synchronizing system for synchronously lifting a nursing bed backing plate and an intelligent wheelchair backing plate of a robot nursing bed. The synchronizing system comprises an infrared transmitting module, an infrared receiving module, a nursing bed control module, an intelligent wheelchair control module and push rod motors, the infrared transmitting module comprises three infrared transmitters, the infrared receiving module comprises three infrared receivers, the nursing bed control module is in communication connection with a nursing bed push rod motor, the infrared receiving module is in communication connection with the intelligent wheelchair control module, and the intelligent wheelchair control module is in communication connection with a wheelchair push rod motor. According to a synchronizing method, by the aid of the principle of a pendulum clock, the states of the three receivers of the infrared receiving module are respectively acquired, so that the three receivers can be correlated with the three transmitters, and the backing plates of an electric wheelchair and a nursing bed are kept parallel. By the aid of the synchronizing system and the synchronizing method, the intelligent wheelchair backing plate and the nursing bed backing plate are synchronously lifted, and the nursing bed and the electric wheelchair can be synchronously lifted and flattened without communication.

Description

technical field [0001] The invention relates to intelligent control, in particular to a synchronization system and a synchronization method for realizing the synchronous lifting of the backboard of the nursing bed and the backboard of an intelligent wheelchair in a robot nursing bed. Background technique [0002] The means of rehabilitation nursing services can be divided into two categories: medical rehabilitation nursing and rehabilitation of nursing aids. Among them, the rehabilitation of nursing aids refers to the means and methods of using rehabilitation nursing aids to provide compensation, replacement, and treatment for the disabled, the elderly, and the disabled. Safe, comfortable and comfortable mobility aids are essential for the disabled to maximize their ability to take care of themselves and participate in social activities. However, to transfer from a bedridden state to a mobile device, the assistance of a nursing staff is necessary, and there is a risk of fal...

Problems solved by technology

[0003] After nursing beds and smart wheelchairs are transformed into beds, there are several ways to complete synchronous sitting up and lying down. Use a mechanical structure to push up the two backplanes at the same time. This method requires high load-bearing requirements for the push rod motor. The volume is large; the wireless communication method is used. In the medical field, due to the various electromagnetic interferences in the special environment of the hospital, wireless communication is less used in the medical field.
