This thesis is based on microprocessor-type pulse detector means, the main research work are as follows: pulse with infrared photoelectric sensor that detects the bodys pulse signal, after two second-order, low pass filter circuit effectively removes frequency noise. Get the analog signal and then through the A / D converted into digital signals, input microcontroller. Single chip pick digital signal pulse of real-time acquisition and analysis of the data processing. Meanwhile, in order to ensure the effective pickup pulse signals, to reduce unnecessary interference power, specially designed for the entire system of linear DC power supply. System can display real time measured by the pulse beats, per minute and the pulse will be measured by comparing the situation with the normal. If the results are quite different, the system will automatically set sound and light alarm. After debugging, the system can more accurately read the pulse of the pulse sensors pick up information, and can display and alarm, so as to achieve the desired design goals. The whole system has a simple structure, small size, high reliability, low cost and easy to use and so on, with higher versatility and value in applications.
