Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] The invention is used for analyzing the gait phase of the human body and the movement pattern information of the lower limbs, so as to make control decisions for intelligent artificial limbs. Such as figure 1 Shown, the present invention comprises the following steps:
[0018] 1) Gait analysis is performed by collecting plantar pressure signals through four pressure sensors arranged on the soles of each foot.
[0019] 2) Perform gait phase analysis on the collected foot pressure signals: compare the pressure sum collected by the four pressure sensors on each foot with the preset threshold, when the pressure sum collected by the four pressure sensors is less than the preset threshold , the sole of the foot is in the swing phase; otherwise, the sole of the foot is in the support phase.
[0020] 3) According to the plantar pressure signal, it i...
