The Multipoint Detection of Pulse Signal and Information Fusion Based on ARM

A detection method of multipoint pulse signal based on ARM9 is presented in this paper. Pulse signals are detected which are on the three parts of wrist, "Cun" "Guan" "Chi", neck artery, and the fingertip. After isolated, amplified, and digitized, Pulse signal enters a DSP anti-interference filter, in which EMG and power frequency signal must be filtered out especially. By using information fusion technology and through GPRS, compared with expert system of the medical service centre, the system can analysis the userpsilas health status. At last cardiovascular-related parameters are displayed on LCD.
