Embedded control system of intelligent wheelchair

Abstract

The invention provides an embedded control system of an intelligent wheelchair, which mainly comprises a dual core processor module, a wheelchair drive module, a distance detection and acquisition module, a voice acquisition module and a voice command database module, wherein the dual core processor module comprises a digital signal processor (DSP) processor and an advanced risc machines (ARM) processor which are in mutual data connection; and the system is configured by using the dual core processor module as a system core, a user can control the intelligent wheelchair through natural language, so the natural man-machine interaction between the user and the intelligent wheelchair is realized, in addition, the distance between the intelligent wheelchair and obstacles in the environment surrounding the intelligent wheelchair can be automatically detected and obstacle warning can be simultaneously sent out, meanwhile, the travelling direction and speed of the intelligent wheelchair can be automatically adjusted according to the distance information and early warning information, the occurrence of accidents due to the collision with the obstacles and the like are reduced, the intelligent level and safety of the intelligent wheelchair are improved, and the embedded control system has low control difficulty, is very convenient to use, and is particularly suitable to be used by the old and the disabled.

Description

technical field [0001] The invention relates to the field of automatic wheelchair technology and embedded control technology, in particular to an embedded control system of an intelligent wheelchair. Background technique [0002] With the acceleration of the aging process of the world's population and the increase of disabled people due to disasters and diseases, how to let the elderly and disabled people regain the ability to move independently is a scientific and technological problem that needs to be solved urgently. Wheelchairs, as the elderly and disabled One of the main means of transportation for people. At present, manual wheelchairs and electric wheelchairs are more common. Compared with manual wheelchairs, electric wheelchairs have greatly improved the ability and scope of independent activities of the elderly and disabled, but at the same time it has brought inconvenience in some environments. and danger. Because the existing electric wheelchairs are usually con...
