A walking training vehicle for rehabilitation and weight loss that realizes straight-line following by detecting distance and its control method

Abstract

The invention relates to a rehabilitation weight-loss walking training vehicle and a control method for realizing straight-line following by detecting distance, belonging to the field of medical equipment, comprising a controller and a distance sensor for detecting the distance between the weight-loss vehicle and the back of a patient; the controller comprises: A distance information acquisition module, a speed control module, and a motor drive module; the distance information acquisition module receives the real-time distance measurement value collected by the distance sensor, obtains the real-time distance value Act_dis at the current moment, and obtains the real-time distance value at the current moment and the set value through calculation. The distance difference Err_dis between the absolute distance values ​​Abs_dis; the speed control module receives the distance difference Err_dis, and uses the PID algorithm to obtain the training vehicle speed correction value Act_speed at the current moment; the motor drive module receives the training vehicle speed value Act_speed and controls the motor to make the training The car is traveling at Act_speed. The invention ensures the synchronization and real-time performance of the coordinated movement of the weight-reducing vehicle and the patient.

Description

technical field

[0001] The invention relates to a walking training vehicle for rehabilitation and weight loss which realizes straight-line following through detection distance, and belongs to the field of medical equipment. Background technique

[0002] In the lower limb rehabilitation period of various clinical patients (such as patients in the recovery period of lower limb motor dysfunction caused by stroke, spinal cord injury, and fracture surgery), auxiliary equipment is needed for weight loss and support. At present, there are not many training equipment in clinical practice, and the demand for rehabilitation continues to expand, but there is a shortage of professional rehabilitation personnel; the one-to-one model is labor-intensive and time-consuming. In order to solve these problems in the process of rehabilitation training, there is an urgent need for new technologies that are safe, quantitative, effective and repeatable.
