Abstract

The invention discloses an intelligent safety wheelchair. A double-closed-loop control system controls the rotation speed of driving wheels so that accurate control over the speed can be achieved. Meanwhile, the intelligent safety wheelchair provides two control modes including user operation lever control and autonomous navigation, automatic obstacle avoidance is achieved, whether the condition of the body of a user is abnormal or not is detected in real time, and corresponding protection measures are taken, so that convenience and safety guarantee are provided for traveling of elder people and the handicapped. Compared with a traditional wheelchair, the intelligent safety wheelchair can detect the condition of the body of the user, and when it is judged that the condition of the body ofthe user is abnormal, an alarm is given out in time, and the action of a motor is stopped. The safety is high, and the wheelchair is particularly suitable for elder people and the handicapped to use.

Description

Technical field: [0001] The invention belongs to the technical field of intelligent auxiliary equipment, in particular to an intelligent safety wheelchair and an intelligent safety control method for the 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. At the same time, there are nearly 60 million people with physical disabilities. - With the development and progress of my country's social civilization, ensuring and improving the quality of life of vulnerable groups such as the elderly and the disabled has attracted more and more attention from people from all walks of life. A large num...
