摘　　要：利用EPLD强大的逻辑处理功能、易于应用的I/O端口和高速处理能力,借助单片机体积小、成本低、易控制、可靠性高、运用灵活等特点,开发了一个便携式数字超声波检测仪器。该仪器不仅具有超声信号的自动采集、存储、显示、分析和处理功能,而且具有输出接口,为数据的进一步处理,实现超声检测的图像化、智能化、自动化奠定了良好的基础。Using the advantages of EPLD (erasable programmable logic device) which is of powerful logic function, I/O port operating easily, high speed operation function, and the specifics of SCM (single-chip microcomputer) which is of small volume, low price, high dependability, using agility, a portable digital ultrasonic-testing device is developed. The device not only has data collection, save, display, analysis and processing, but also has output interface. For the developing of imaging, intelligent and automation of ultrasonic-testing, a very good foundation is established by this device.
