Problems solved by technology
Therefore, the elderly need to be taken care of by nursing staff in their daily life. However, the number of rehabilitation nursing staff in our country is currently insufficient. Therefore, how to ensure that the disabled elderly and the disabled population have the ability of daily life without sufficient nursing staff has become an urgent problem to be solved. The problem
The widespread application of smart wheelchairs has relieved part of the burden on nursing staff, but the initial interaction between the robot and its users still requires the participation of nursing staff
[0003] Wu Xuetang of Shenyang University of Technology's 2016 master's degree thesis "Intelligent Wheelchair Detection and Control System Design" in the wheelchair control method is not ideal for reducing the impact of the human body in contact with the chair surface.

Embodiment Construction
[0069] In the process of sitting down, the present invention detects the current posture of the human body and judges what state it is in.
[0070] After judging that the human body is in an uncontrollable state, the present invention calculates the time when the human body is in contact with the chair surface and the posture change when it is in contact with the chair surface.
[0071] When the present invention contacts the human body with the chair surface, the smart wheelchair (with a microprocessor inside the wheelchair, the wheels when the wheelchair moves is controlled by the motor, and the rotation of the motor is controlled by the microprocessor. The wheelchair can move forward, backward, left, and right, and the chair of the wheelchair Between the surface and the chassis for movement, the motor controls the chair surface of the wheelchair to move up and down, and the motor is controlled by the processor. The sensor in front of the wheelchair measures and calculates th...

A wheelchair control method belongs to the technical field of human body rehabilitation, and the invention in particular relates to the wheelchair control method. The present invention provides the wheelchair control method that can reduce the impact experienced when the human body contacts a chair surface. The invention comprises the following steps: (1) detecting the current posture of the humanbody and judging whether the current posture is in a controllable state or an uncontrollable state during the sitting process; (2) calculating the time that the human body contacts the chair surfaceand the posture change when the human body contacts the chair surface, after judging that the human body is in the uncontrollable state; and (3) when the human body contacts the chair surface, controlling the movement of the wheelchair in the positive direction of the impact force at the output expected speed of the wheelchair, and reducing the impact force on the human body by reducing the changeof the speed.
Description
technical field [0001] The invention belongs to the technical field of human body rehabilitation, and in particular relates to a wheelchair control method. Background technique [0002] Elderly people will be unable to control their body posture due to lack of muscle strength in the lower limbs or pain in the legs when sitting down, resulting in a greater impact on the body when they sit on the chair. This creates a degree of discomfort and increases the likelihood of potential hazards such as the wheelchair tipping over. Therefore, the elderly need to be taken care of by nursing staff in their daily life. However, the number of rehabilitation nursing staff in our country is currently insufficient. Therefore, how to ensure that the disabled elderly and the disabled population have the ability of daily life without sufficient nursing staff has become an urgent problem to be solved. The problem. The widespread application of smart wheelchairs has relieved part of the burden ...
