ABSTRACT

High-precision trajectory tracking facilitates high-quality medical care. In this paper, a trajectory tracking and alarm system constrained by time and space norms are designed based on the emergency scene. The location data are collected based on the UWB positioning platform, and the K-means clustering filter and TDOA solve the location. The horizontal positioning accuracy is less than 30cm. Furthermore, the rules of space and time were set up according to the requirements of admission, and the emergency patients were monitored through the statistical information of location, path, time, and so on, and the abnormal behaviours or abnormal areas were alerted. The simulation results show that the system can realize the basic functions of real-time viewing of the position, moving track, and alarm of emergency patients and can effectively meet the needs of hospital emergency patients' fine management service.
