Since the method of current subjective judgement of Taichi Pushing Hands (with Fixed‐foot Stance) lack sobjec‐tive standard ,to a certain extent ,it has affected the development of this sport .Focusing on the evaluation points ,such as footwork ,loss of center of gravity ,etc .of Taichi Pushing Hands (with Fixed‐foot Stance) ,this paper is based on the sensor technology which is composed of “foot movement recognition”and“hand movements recognition”to analyze the re‐quired function of the system .Therefore ,the author puts forward the overall design of the proposed system and the pro‐grams of action recognition ,and researches its subsystem modules ,in order to serve the fitness and competitions of Taichi Pushing Hands (with Fixed‐foot Stance) .%鉴于现行太极（定步）推手主观判分方式缺乏相应的客观性和标准性，在一定程度上影响该项目的发展，本研究针对太极（定步）推手运动对脚步移动、失去重心等评判点，研制一种基于传感技术由“脚部运动的识别”、“手上动作的识别”组成的自动识别系统，分析该系统所需要的功能，提出该系统的总设计和动作识别方案，研究其子系统模块，以服务太极（定步）推手的大众健身和运动竞赛。
