电子脉搏计设计
中医神奇的地方在于望闻问切，而切正是指对脉搏的诊断，脉搏跳动主要是动脉内的血液按照周期循环流经整个身体产生的波动，人体的脉象中包含有关心脏、神经和内外循环等ed into main control module,signal acquisition module, display module, buzzer module, keyboard module. Pulse meter using infrared sensors to collect the pulse signal, after shaping and amplifying,enter the signal to the single chip microcomputer to corresponding control, which measured within the pulse beat frequency in a minute, convenient and fast. System main control chip use STC89C52, the pulse signal acquisition to display on the LCD 1602.
I in electronic pulse meter design, step by step in different functional modules of study, to the core of the scientific and technological achievements of the study before and now better components, compare, and finally to every part of the final choice together, form a complete excellent electronic pulse meter, so we can understand the specific component model and the function, not only in theory of textbooks. I am in the process of classification, comparison and design, system review again the university to study a variety of professional knowledge, and to many disciplines together, flexible application. In the end, I start to make the electronic pulse meter, when their own design electronic pulse meter physical done finally, accurate measured their pulse of The Times, a kind of happiness to let my heart excited, I know it will be a stepping stone in my life, let me confidence further.
Keywords: electronic pulse meter 51 single chip microcomputer hardware design software design
