Fast stepless pneumatic pressurization collection system and method of pulse condition

The invention discloses a fast stepless pneumatic pressurization collection system and method of a pulse condition. The system comprises a gas path module, a pressure sensor, a power supply module, asignal adjustment module and a microcontroller module; the gas path module is used for collecting pulse information, and the pressure sensor is used for transmitting the collected pulse information tothe signal adjustment module. The method comprises the following steps: step 1, collecting pulse condition information and obtaining pulse condition data from a pulse condition instrument; step 2, carrying out drift correction treatment on the collected pulse signal, obtaining pulse condition data under different pressures, and then extracting time-domain characteristic parameters; and step 3, extracting the peak value of a main wave peak of each periodic pulse graph by an ILP algorithm, taking the pressure corresponding to the peak value as the abscissa, drawing a scatter diagram and fittingto obtain a wave peak valu
