Description
technical field [0001] The invention relates to the field of electronic control, in particular to a control system for hardware control of an ultrasonic flaw detector and a control process thereof. Background technique [0002] Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument, which can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece. More and more extensive, therefore, the technical requirements for acoustic flaw detectors are also increasing. [0003] At present, the control system of the ultrasonic flaw detector is mainly composed of the following parts: analog-digital sampling chip, logic control chip, single-chip microcomputer, main chip FPGAⅠ, synchronous dynamic memory, flash memory chip, display control chip and FPGAⅡ. The main process is as follows: the waveform signal obtained by the ultrasonic p...
