Human-computer interactive intelligent wheelchair

Abstract

The invention discloses a human-computer interactive intelligent wheelchair which comprises a wheelchair body, two driving rear wheels, two driven front wheels, a storage battery, two driving motors, a human-computer interactive device, an operation rod and a motor driver, wherein the wheelchair body comprises a table top and two pedals. The human-computer interactive intelligent wheelchair is characterized in that an embedded control system is installed in the table top, a controller of the embedded control system is a 16-bit SPCE016A singlechip, an ultrasonic autonomous navigation mechanism is distributed at the lateral portion of the wheelchair body, and a voice control mechanism and a vision autonomous navigation mechanism are distributed on the wheelchair body. The ultrasonic autonomous navigation mechanism, the voice control mechanism and the vision autonomous navigation mechanism are respectively in telecom connection with the embedded control system which is further in telecom connection with the operation rod and the motor driver, and the storage battery provides power for the driving motors. By mean of the human-computer interactive intelligent wheelchair based on the 16-bit SPCE016A singlechip serving as the controller of the embedded control system, the problems that the existing human-computer interactive intelligent wheelchair based on a universal computer controller has high cost, large power consumption, poor cruising capability and the like can be solved well.

Description

technical field [0001] The invention belongs to the field of electric wheelchairs, in particular to a human-computer interaction intelligent wheelchair. Background technique [0002] According to the forecast of the United Nations, the average annual growth rate of the world's aging population from 1990 to 2020 is 2.5%, and the increasing rate of my country's aging population is 3.3% in the same period, and the aging rate is faster than the world's aging rate. Compared with other countries, China has a high degree of population aging and has gradually entered an aging society. In many big cities, such as Shanghai and Beijing, the proportion of the elderly is close to 20%. At the same time, there are nearly 6,000 people with physical disabilities. Ten thousand. Among them, quite a few have to rely on wheelchairs to live because of walking inconvenience. However, for many elderly people, it is not very convenient to use ordinary wheelchairs, and the quality of life is signif...
