介绍采用ＰＣ系列微机对压缩机指示图进行录取的方法。该方法对气缸内的动态压力信号、压力标定信号及活塞上止点信号进行数据采样，并根据实测采样数据，对指示功率、相对压力损失等进行了分析、计算。
Introduce the method of adopting PC series microcomputer to admit the compressor indication chart. The method samples the dynamic pressure signal, pressure calibration signal and piston top dead center signal in the cylinder, and analyzes and calculates the indicated power and relative pressure loss according to the measured sampling data.
