利用互相关器实现的智能涡流检测系统能有效抑制干扰信号，具有很高的缺陷的检出能力和检测可靠性。
The cross correlator which realises intelligent eddy current inspection system can effectively restrain the interruptive signal and has high defects detecting ability and reliable inspection.
传感器检出的信号送入信号处理电路后，经滤波、放大、整形及合成，成为等效于滞燃期的数字脉冲信号。
The signal read out of the sensor is to be filtered, amplified, shaped and synthesized and then transformed into a digital pulse one, which is equivalent to the ignition time delay.
反相器(145、146)将该冲击检出信号(S22、S23)与阈值进行比较，当超过阈值时就是检出冲击。
Inverters (145), (146) compare these impact detecting signals (S22), (S23) with a threshold value and detect an impact when the signals exceeds the threshold value.
识别器检出与轨迹信号相对应的图文记号后，微控制器将其存入内存中，并由显示器显示选出的图文记号。
After the identifier finds out graphic marks corresponding to the trace signals, the micro-controller stores it in the memory and the display displays the selected graphic marks.
