Abstract: Pulse signal contains important information of heart and blood vessels status. At present, China’s for cardiovascular disease monitoring to cable way, have bulky and expensive shortcomings, not easy to community health and family health care. This paper integrates application of mobile communication technology, embedded technology and electronic information processing technology, develops a visualization, wireless pulse monitoring system. The system includes pulse transducer, intelligent terminal users and remote monitoring center three parts. Pulse sensors collect pulse signal; intelligent terminal processes, and storages signal, with GPRS to finish data upload and receiving; remote monitoring center analyzes data, and uploads terminal diagnosis and recommendations issued by wireless means to user terminals. This system can be used as a family care and remote medical auxiliary equipment, it is suitable for the community and the family health care, so it have broad application prospect.
