In order to better meet the life needs of the elderly, it is very important to break through the traditional pension mode, and to build a healthy, harmonious and beautiful living environment for the elderly through situational awareness information. The elderly not only need to be healthy and comfortable in material life, but also need to know their health status. Situational awareness refers to the application of some good mechanical equipment to obtain the relevant situational information of the elderly through perception, and then apply the information to provide relevant services for customers to meet the needs of the elderly. Therefore, this paper analyzes the situation awareness and the design of traditional elderly care service centers, and then innovates traditional elderly care service centers through the theory of situation awareness, so as to better meet the requirements of elderly care service centers.
