| Abstract: | According to the shortages of the traditional ultrasonic detectors in online inspection,such as low anti-interference capability and sensibility,through introducing the theory of ultrasonic detection system,a circuit module for signal collecting and amplifying of multi-functional ultrasonic detection system is designed.It is introduced the structural design,working principles and performance of the four circuits of the module,i.e.synchronous circuit,trigger-transmitter circuit,clipping-amplifying-detection circuit and gain control circuit.The circuit module satisfactorily solves the existing demerits of low anti-interference capacity and low sensibility of traditional ultrasonic defect detectors when doing on-line inspection. |
