Multifunctional intelligent wheelchair based on bus control system and vital signs cloud monitoring

Abstract

The invention discloses a multifunctional intelligent wheelchair based on a bus control system and a vital sign cloud monitoring. The multifunctional intelligent wheelchair comprises the following parts: a wheelchair mechanical structure, which has three states including sitting, standing and lying through deformation transformation; a wheelchair intelligent control system, which is connected to each system through a UM-BUS bus equipped with three MLVDS signal channels and is used for controlling the coordinated operation of each system and the movement of the wheelchair; a sign detection system, which is used for detecting body temperature and pulse data of a user, wherein the body temperature and pulse data is uploaded to a cloud server, and when the physical information of the wheelchair user exceeds normal value, a short message is sent to notify a mobile end of an emergency contact; and a pressure sensing system, which is evenly spread over a cushion area and armrest areas on bothsides for outputting the collected pressure data to the wheelchair intelligent control system. The multifunctional intelligent wheelchair has the advantages of simple operation, powerful functions, reliability and scalability, and can realize intelligent automatic control of the wheelchair and facilitate monitoring of the user for quick medical treatment.

Description

technical field [0001] The invention relates to the field of medical and elderly care machinery products, in particular to a multifunctional intelligent wheelchair based on a bus control system and vital sign cloud monitoring. Background technique [0002] In 1986, the first intelligent wheelchair recognized by the world was born in the UK, and subsequently, many countries have also invested in research on intelligent wheelchairs. [0003] The wheelchair robot MAIDM developed by the University of Ulm in Germany is one of the earliest fully automated intelligent wheelchair products. Japan's TAOAide smart wheelchair can collect and transmit data through GPS and other tools to locate the wheelchair in real time. [0004] Restricted by the level of economy and technology, the development of smart wheelchairs in my country is relatively late compared with European and American countries, but still achieves more research results. In 2010, the Institute of Automation of the Chine...

AI Technical Summary

Problems solved by technology

[0005] From the above overview, it can be seen that my country's smart wheelchairs are in the stage of experimental research and design, and the technology and results of the research do not fully meet the needs of target users, and the intelligence is generally insufficient.

At present, most of the wheelchairs in the domestic market are only in the mode of human-computer interaction, and the actions of wheelchairs are controlled by people actively, which is not intelligent enough.

At the same time, the added value of wheelchairs is not much. Most wheelchairs can only perform simple functions such as simple forward and backward, and cannot make full use of the unique structure of wheelchairs for design. There is still a lot of room for research.

At the same time, most of the wheelchairs on the market adopt the traditional system control mode, resulting in a poor connection with emerging technologies
