System for collecting and processing information of plantar pressure distribution of wearable power-assisting robot

Abstract

The invention relates to a system for collecting and processing the information of plantar pressure distribution of a wearable power-assisting robot. The system comprises a fore-end device for collecting the information of the plantar pressure distribution and a terminal-side information processing unit, wherein the device is particularly a layered-structure flexible foot of the power-assisting robot; collecting points are biomechanically distributed at the plantar part; a flexible pressure sensor is stuck to the plantar part; meanwhile, force-conducting rings are stuck to the upper side and lower side of the flexible pressure sensor, so that the plantar pressures at each phase during the walking process of the human body can be distributed on the mounted sensor; and the information processing unit is used for collecting the pressure values of each pressure point according to sequential control and transmitting the pressure values to the processing unit of an upper computer to perform the functions of storage, analysis and display after the pressure values are subjected to A/D (analog-to-digital) conversion by a collecting card, thus providing the low-redundancy and high-accuracy information of the human plantar pressure distribution for the subsequent algorithm. The system of the invention has the advantages of high reliability and low cost. Therefore, the invention is of more significant application value in the field of power-assisting robots and clinical research on foot diseases.
