Multifunctional intelligent wheelchair control system and control method

Abstract

The invention relates to a wheelchair control technology, in particular to a multifunctional intelligent wheelchair control system and control method. The control system comprises a controller, a safety decision module, a direction control module, an alarm module and a power module; the controller comprises a main controller and an auxiliary controller; the safety decision module comprises an obstacle avoidance recognition device and a wheelchair state recognition device; the direction control module comprises a rocker and a voice recognition device; the main controller is connected with the safety decision module and the direction control module; the auxiliary controller is connected with the main controller and the voice recognition device. The safety decision module adopts ultrasonic wave and infrared combined decision making, when an obstacle is recognized, the wheelchair can avoid the obstacle emergently, the state recognition module can recognize whether the wheelchair rolls over or topples over in the advancing process, and the positioning infomration is sent to an emergency contact person through 5G positioning information in danger. The system can realize the functions of automatic obstacle avoidance, danger alarm, voice control and the like of the wheelchair, and has the advantages of high performance, simplicity in operation, high safety and the like.

Description

technical field [0001] The invention belongs to the technical field of wheelchair control, in particular to a multifunctional intelligent wheelchair control system and a control method. Background technique [0002] With the acceleration of the aging process of the world's population, due to the increase of disabled people caused by disasters and diseases, the quality of life of vulnerable groups such as the elderly and the disabled has received more and more attention. The ability to move will not only make their daily life more convenient, but also have a profound impact on their mental health, self-evaluation, and mental state. Therefore, a multifunctional intelligent control wheelchair plays an important role for the elderly and disabled. [0003] Since manual wheelchairs must be pushed by manpower, it is very troublesome when users want to move by themselves, so electric wheelchairs came into being. Compared with manual wheelchairs, electric wheelchairs can greatly imp...

AI Technical Summary

Problems solved by technology

[0004] At present, smart wheelchairs either have no obstacle avoidance measures, or only use ultrasonic or infrared sensors for obstacle avoidance, and the use of a single sensor is easily affected by environmental factors such as temperature and humidity, which can easily lead to misjudgment

And when a real danger occurs, the existing technology mostly uses sound and light alarms to obtain the attention of strangers nearby, and this method is not only useless
