Problems solved by technology

[0003] For handle-operated wheelchairs, most domestic electric wheelchairs are currently developed based on the handle for the lower computer. The lower computer must be developed according to the handle agreement, and the handle agreement needs to be purchased, which is generally expensive; and the handle must be connected to a single-chip microcomputer and installed in a fixed position, which is not flexible enough; At the same time, due to the strange baud rate value, it cannot support host computers such as Raspberry Pi or PC, which is not conducive to the intelligent modular development of wheelchairs.

Embodiment Construction

[0036] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0037] The invention discloses a method for operating a wheelchair based on a wireless handle. The wireless handle is provided with a rocker. The rocker has the ability to shake horizontally and up and down. The driving of the wheelchair is controlled according to the values ​​of the rocker horizontally and up and down. The rotation speed of the wheel motor is realized to control the movement of the wheelchair. like figure 1 As shown, the specific steps include:

[0038] S1. Calculate the velocity V and direction θ of the wheelchair according to the horizontal shaking value X and the vertical shaking value Y of the rocker, where:

[0039]

[0040]

[0041] where (X 0 ,Y 0 ) is the center coordinate of the rectangular range where the joystick shakes horizontally and up and down;

[0042] S2. Calculate the speed of the wheelchair drivi...

Abstract

The invention discloses a method and a system for operating a wheelchair based on a wireless handle, the wireless handle is provided with a rocker, the rocker has the capability of shaking horizontally and vertically, and the rotating speed of a wheelchair driving wheel motor is controlled according to the horizontal shaking value and the vertical shaking value of the rocker. The handle can be placed according to the requirement of a user, and the movement of the wheelchair can be operated only through the rocker on the handle.

Description

technical field [0001] The invention belongs to the technical field of wheelchairs, and in particular relates to a method and system for operating a wheelchair based on a wireless handle. Background technique [0002] As an application platform of robotics, smart wheelchairs can allow people with different degrees of disabilities to control wheelchairs, which can greatly improve the quality of life of users. The intelligence of wheelchairs depends on computers and sensors. Most of the current solutions add host computers to process information from sensors. In order to mass-produce intelligent wheelchairs, modularization must be achieved. The entire system should be composed of basic modules and various functional modules. Each functional module is responsible for a function. Users can choose and configure suitable wheelchairs according to their needs. Cost, improve cost performance. [0003] For handle-operated wheelchairs, most domestic electric wheelchairs are currently...
