Abstract

The invention provides a laser ranging based stair climbing wheelchair control system suitable for the technical field of wheelchairs. The system includes a laser ranging module used for detecting a first distance between a track and stairs with laser; a seat balancing module used for controlling steering and rotation speed of a seat push rod motor so as to adjust seat posture of the stair climbing wheelchair according to the inclination angle of the seat; a Hall control module used for controlling the operation of a motor of the stair climbing wheelchair according to control commands currently input into the Hall controller. At the same time, the invention also provides a laser ranging based stair climbing wheelchair control method. Therefore, by using laser ranging for improving wheelchair barrier avoiding performance and through controlling the wheelchair during the stair climbing process, bumping of the wheelchair during the stair climbing process is avoided.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to a control system and method for a stair climbing wheelchair based on laser ranging. Background technique [0002] With the development of society, people have higher and higher requirements for travel, but this has become a luxury for the elderly and physically disabled, especially when encountering complicated road sections such as steps and stairs. Hope to have a means of transportation. The wheelchair has become the key to solving this problem. It can solve the travel of the elderly and physically disabled patients. However, ordinary wheelchairs are powerless when encountering complex terrain such as obstacles and stairs. The intelligent electric obstacle-climbing wheelchair is a new type of mobility assistance equipment developed under the background of the country's advocacy of caring for vulnerable groups and creating a harmonious society, which is suitable for people ...
