Research Of Pulse Signal Processing Methods And Design Of Pulse Measuring System

From pulse diagnosis of Chinese herbalist doctor to the research of cardiovascular system by modern iatrology, they all have showed and proved that human pulse has a good affinity with diseases, especially cardiovascular diseases. Human pulse contains much physical information, it will be propitious to know the human healthy state early so that to get therapy and recovery early when it is often detected. It is important valuable to make a diagnosis and treatment for cardiovascular and chronic diseases. Pulse signal processing effectively and high quality signal acquiring have a decided effect to computing and analyzing diseases'parameters.Based on the existing pulse processing methods and detecting technologies, we explored them profoundly, two creative processing methods were offered for human pulse, and finished pulse measuring system. The main workloads were as following. The first was information fusion of multi-points pulses based on pulse entropy. It realizes to distill the largest information and to fuse multi-channels pulse signal to one channel high quality signal which has largest information and a smaller data quantity, it is useful for computing parameters and data storage of pulse. The method has a good universality for other signals'applications.Second, a new type character pulse cycle chose method was K value wave-chose way. It broke the traditional idea that only chose one pulse circle wave, in fact, appropriate character circle waves should be the analyzed objects. The chosen standard was according to the K value which was proved to be a valuable parameter of pulse. The method has a factually application value.The third was to design and realize two types of pulse measuring system. One was high speed and multi-channels pulses measuring system based on PCI data acquisition, the other was portable pulse measuring system based on MSP430 MCU control. They could acquire good pulse signals.At last, we explored the future application of pulse measuring and processing system. It will be used broadly in the FITS which is family interactive telemedicine system. People hope they can get some routine physical examination and diagnosis conveniently especially at home. It will be a future trend and a good way of seeing doctors. FITS could realize people's wish. It could improve the diagnosis efficiency and save much social resource. Therefore, there is a great market requirement in the future for pulse measuring and processing system and others'measuring physical information system.
