Abstract

The invention provides a gait control method, comprising: providing gait model and reference information; collecting original gait information and judging gait type according to the gait model; collecting the state information of the booster module and converting the state information into the parameter information; invoking the reference information and the parameter information to compare according to the gait type; and sending an adjustment instruction to the booster module so that the parameter information conforms to the reference information. The gait model of the gait control method ofthe present invention includes a foot-flattening model, heel off-ground model and toe off-ground model, at the stage when the wearer needs power assistance or adjustment, the comparison basis is provided, and the reference information is combined to enable the gait control method to realize the control of the power assistance module without re-determining the gait period, thereby avoiding the problem of tracking speed and precision degradation caused by continuously re-determining the gait period. The invention also provides a gait control system for realizing the gait control method.

Description

technical field

[0001] The invention relates to the technical field of exoskeleton robots, in particular to a gait control method and a control system for a lower limb assist exoskeleton robot. Background technique

[0002] The lower limb assisting exoskeleton robot is a wearable assisting device that can be organically combined with the user to help people with lower limb motor dysfunction recover their walking ability. Human-machine interface is a way to realize the communication between human and lower limb assisting exoskeleton robot. Its function is to analyze and predict the gait data of human body. Since gait is a continuous periodic movement, including a lot of complex physiological information, gait analysis aims to detect and analyze the changes in physiological parameters such as movement trajectory, contact force information, and electromyographic signals during this process. The computer transmits the control signals generated after analyzing and processing the...
