Abstract
This design is mainly about the pulse measuring instrument related solutions. In view of the particularity of the pulse signal, when study must pay attention to the correctness of the signal measurement, so the design key points of this scheme lies in the realization of this system to the greatest extent lightweight and accurate. The system by measuring the pulse of The Times for 10 seconds, calculate the number of pulse per minute. The schemes to STC12C5608AD microcontroller as the control unit of the system, to complete the signal acquisition and pulse measurement tasks. Used in the design of the photoelectric sensor to realize the collection of the human pulse signal, then carries on the amplification, filtering, plastic, and the square wave signal and pulse synchronization, again through the microcontroller wave signal counting and timing. The data will be through Nokia5110 screen display. In the course of single-chip microcomputer, using DS1302 real-time display the current time. This paper illustrates the working process and its composition of human pulse measuring instrument circuit performance analysis.
