Cardiovascular Disease Early Warning System

With the more and more pressure coming from society and improvement of live level, people put more focus on their own health. So effective medical diagnostic methods and devices become the hotspot of researches. Pulse is the most important, sensitive and reliable information of human activities and it indicates the status of human healthy. Sampling and analysis from the pulse can find early symptoms of certain disease, thus prevent the disease become worse.As the development of the pulse detect theory, the examples of the usage of this theory on clinic become more and more on broad, while it is just begin in our country. This paper designed cardiovascular disease early-warning system based on this pulse wave analysis theory, whose function is detecting pulse signals, display the status of cardiovascular in real-time, when the cardiovascular is abnormal, it can issue an alert message. This system takes the advantages of embedded system and the request present a new solution, which is composed of a front embedded system and a backend analysis system. The front embedded system mainly handles the collection and basic process of pulse signal, which can work alone, while the backend system mainly handled the storage of data, and make senior process of the signal. The two can both work alone without each other, and becoming a two-part aided diagnosis system for the doctor and the sick. The system has two main functions - short term and long term. In the aspect of short term it can rise alarm when the cardiovascular is abnormal, in the aspect of long term, it can provide a reference for the doctor, which is important for the doctor to present an advice when the function of cardiovascular display a decrease trend.This paper presents the system design of cardiovascular disease early-warning system, including system topology structure and the front embedded system and the backend analysis system. Then put main focus on the reality of every component. The base theories of the pulse detecting and spectral analysis are introduced, as well as some arithmetic used on the system. Then the arithmetic in the environment of embedded system is analyzed with deep research on the optimization. At last summarizes the work of this paper, points out the future of the system.
