【Abstract】 This thesis introduces the principle and method of an A-type-pulse-reflection ultrasonictesting system that based on Motorola DSP56F805. It mainly proposes a means to achievethe function of ultrasonic measuring-distance and testing-lacuna with DSP56F805,ultrasonic transmitter and the peripheral circuit. In this paper, the hardware and softwarestructure of the ultrasonic testing system is discussed and practiced.更多还原
