Abstract

The invention discloses a trunk center-of-gravity shift based rehabilitation device walking triggering control method. The method comprises the following steps: (1) judging a parallel standing posture; (2) judging walking triggering conditions, namely analyzing and processing, by a control module, data acquired by a sensor to judge whether the following conditions are met: if the conditions C5 and C7 are met at the same time, a triggering condition for striding a right leg is met; if the conditions C6 and C8 are met at the same time, a triggering condition of striding a left leg is met; and if the conditions C5 and C7 or the conditions C6 and C8 are not met at the same time, the control module continuously detects the data of the sensor so as to judge the user posture; (3) controlling walking triggering; and (4) continuously detecting the data by the control module to judge the inclination angle of the trunk, the pressure of the sole of a foot and the data of a crutch pressure sensor so as to enter a walking maintenance state. According to the method disclosed by the invention, a trunk inclination angle sensor is adopted, a crutch touchdown pressure sensor judges the gravity center of a user, and then under the premise of ensuring the safety of the user, the triggering control from the parallel standing posture to a walking state is realized.

Description

technical field [0001] The invention relates to a walking control method of a rehabilitation device, in particular to a walking trigger control method of a bionic exoskeleton rehabilitation device based on a trunk center of gravity offset, and belongs to the technical field of rehabilitation engineering. The wearable bionic exoskeleton mechanical leg rehabilitation device is referred to as the rehabilitation device. Background technique [0002] In recent years, due to the rapid development of economy and technology, there are more and more means of transportation. According to relevant survey data, the traffic accident rate in China is 8 times that of developed countries. Upward trend. At the same time, with the improvement of people's living standards, there are more and more people suffering from cardiovascular and cerebrovascular diseases or nervous system diseases, and they are also showing a younger trend in age. Most of these patients are accompanied by hemiplegia sy...
