Research and Development of Photoelectric Pulse Test System

The system identifies the pulse signal adopting the self-regulating transmissive finger pulse sensor .The 89C51 controls data processing, data display and keyboard input. Matrix LCD EDMl6032B displays the data and wave. The system makes the pulse test technology intelligentize. The main idea of the system is that the pulse numbers and the pulse wave used as cardiograph can be displayed by EDM16032B full screen matrix LCD. The intensity and rule of heartbeat can be observed by the wave in LCD.
