Research On System Of Pulse-tracing Collection

It is well known that pulse-taking is very important in department of traditionalChinese medicine, Herbalist doctors think that they can gain sufferer's pathogeny andsymptom by pulse tracings. When doctor takes in clinic pulse-taking, cognition topulse tracings combines experience of finger and comprehend to pulse tracings. Butthe pulse tracings are difficult to be commanded, and the standard of distinguish isfuzzy, so there are much difficulties and divergence in teaching and clinic.Pulse-taking must be objective for tending towards the world. Now, along with the development of machine and electronics, there areprogresses in manufacturing electropulsogragh. But the electropulsogragh can onlygive the wave of sufferer's pulse information, it cannot save them, so we cannotprocess the information. In the thesis, this problem is solved. In the thesis,we adopt the method of circle collection with one channels whencollecting pulse tracing, namely, the six route pulse tracing shared one amplificationsystem and one A/D translation circuit. I control them by using analog channeloption switch CD4051 and the single chip ADuc812. ADuc812 accompanied with 8 ways of ADC and 2 ways of DAC, so it can dotranslation and controlling by itself. Furthermore the single chip ADuc812accompanied with a flash program memory of 8k bytes, a flash data memory of 640bytes, and a data memory of 256 bytes. The program's composition of this singlechip and download is very convenience, and the debugging of the single chip is alsovery convenience, we can debug it when we want, and the single chip needn't betaken out, so we needn't buy specialized development system of single chip. In thisthesis, I collect pulse tracing by using the single chip ADuc812, the effect is verywell.
