Embodiment Construction

[0072] Such as figure 1 As shown, the electric wheelchair control system with multi-attitude adjustment includes a hand operator module 1, a CAN communication module 3, a controller module 2, a differential motor drive module 5, an electric push rod drive module 6, and a power supply module 4.

[0073] Among them, the communication between the handheld module 1 and the controller module 2 is carried out through the CAN communication module 3, and the controller module 2 outputs two control signals, one signal drives the DC brushed motor to run at a differential speed, and one signal drives the electric push rod motor Adjust the posture of the wheelchair. The power supply module 4 is used to supply power to the handheld terminal module 1 and the controller module 2, and is a 24V battery power supply.

[0074] Such as figure 2 As shown, the handheld operator module 1 includes a handheld operator ARM controller 101, a switch button and a power indicator light module 106, a joy...

Abstract

The invention discloses a multi-attitude adjusting electric wheelchair control system, which comprises a manual operator module, a CAN communication module, a controller module, a differential motor driving module, an electric push rod driving module and a power supply module, wherein the manual operator module is used for carrying out operation control on a wheelchair; the manual operator module and the controller module are communicated through the CAN communication module; the controller module controls the differential motor driving module to drive a motor to operate in a differential manner and controls the electric push rod driving module to drive an electric push rod to carry out attitude adjustment; and the power supply module is used for providing power for the manual operator module, the controller module, the CAN communication module, the differential motor driving module and the electric push rod driving module. Through the electric wheelchair control system, problems of electric wheelchair operating lever zone control, electric wheelchair multi-attitude adjustment and motor position information feedback monitoring can be solved, and the electric wheelchair is enabled to have the characteristics of functional diversity, acceleration and deceleration smoothness, turning operation comfort and safety and closed-loop smoothness.

Description

technical field [0001] The invention relates to a control system of an electric wheelchair, which is used for controlling the posture adjustment of the electric wheelchair and the differential operation of dual motors of the wheelchair. Background technique [0002] my country's aging society is developing rapidly. By the end of 2014, there were more than 24 million elderly people over the age of 80 in my country, nearly 40 million disabled and semi-disabled elderly; more than 80 million disabled people, and about 8.77 million physically disabled people. people. The walking and rehabilitation of these disabled, semi-disabled elderly and physically disabled people are the biggest problems. As the most important means of transportation for the elderly and the disabled, the wheelchair is convenient for the walking of the disabled elderly and the physically disabled. However, ordinary manual wheelchairs and electric wheelchairs do not have the function of posture adjustment and...
