Obstacle crossing type electric wheelchair based on DSP technology protection motor

Abstract

The invention relates to the field of electric wheelchairs, in particular to an obstacle crossing type electric wheelchair based on a DSP technology protection motor. The obstacle crossing type electric wheelchair comprises a framework, an arm chair, obstacle crossing front wheels, obstacle crossing rear wheels, a rotary driver, a clutch, an industrial computer and a DSP controller, the arm chairis fixedly mounted on the top surface of the framework; a liquid crystal display module and an operation module are arranged on the arm chair; each obstacle crossing front wheel comprises a front wheel support and a plurality of universal wheels. An inertial sensor is fixedly installed in the front wheel support; each obstacle crossing rear wheel comprises a rear wheel support and a plurality of rolling wheels, the rolling wheels are rotatably installed on the rear wheel support and evenly distributed around a rotating shaft of the rear wheel support, and one rolling wheel is in transmission connection with an output shaft of a second motor; the liquid crystal display module, the operation module, the clutch, the inertial sensor and the DSP controller are all electrically connected with the industrial computer, and the rotary driver is electrically connected with the DSP controller.

Description

technical field [0001] The invention relates to the field of electric wheelchairs, in particular to an obstacle-crossing electric wheelchair based on DSP technology to protect a motor. Background technique [0002] Electric motors are widely used in the production and life of human society because of their simple structure, sturdy and durable, simple control, convenient use and adaptability to various complex working environments. [0003] Due to the lack of safe and reliable protection measures for the motor, such as motor short circuit, overload, broken Xiang, stalled rotor and other operating faults, these faults will cause about 300,000 motors in the country to be seriously burned every year, which will cause serious damage to enterprises. severe economic losses. [0004] Most of the large high-voltage motors used in iron and steel enterprises, mines, and coal mines are imported from abroad, the cost of the equipment itself is very high, and it has been working in an ex...

AI Technical Summary

Problems solved by technology

[0008] The action and obstacle surmounting of the wheelchair disclosed in this patent depend on the drive motor and the electric push rod, and the electric push rod also drives the push rod to reciprocate in a straight line through the motor, so the wheelchair uses a large number of motors. Once one of the motors fails, the There may be a danger of the user falling from the wheelchair, and the wheelchair has a complex structure and a large volume, and obstacle clearance depends on manual operation, and cannot automatically break through obstacles that the user does not notice
