The work aims to expound the problems and development trends in the design of wearable intelligent equipment based on the analysis of the basic characteristics of wearable intelligent equipment and the overall demands of "human and environment" in emergency rescue. The functional demand indexes of wearable intelligent equipment in emergency rescue were established by KJ affinity graph, and 1 target level, 4 first-level indexes and 11 second-level indexes were obtained. Then, AHP was used to comprehensively evaluate each functional demand index, and get the weight value of each index. Through the research of sensor, motion control, new manufacturing, new materials and other key technologies, the problems of information processing and decision, motion control, new material application, etc. were discussed. The design principle with function as basis and safety as assurance was established, emphasizing human-machine interaction experience, focusing on physiological comfort and improving scientific and technological aesthetics. The method of system design and the appearance design strategy were clarified. The system design model including operation principle, information collection and feedback, intelligent motion was constructed. It provides basic data and theoretical basis for the design process, thus realizing the optimal and innovative design of wearable intelligent equipment for emergency rescue.
