A novel double-crystal water film probe with one transmitter and four receivers was developed based on the conventional probe with one transmitter and one receiver for steel plates automatic inspection.
经多次实验测试表明,一发四收探头具有声束宽,定量精度高,水平分辨力高等多项优势,从而提高了中厚钢板自动探伤的技术指标。
Both PLC and IPC are used to control the detecting procedure of an ultrasonic automatic flaw detecting system.
对车轴超声自动探伤作业的流程控制进行了研究,提出了工控机与PLC相结合的设计方案;采用“指令”与“报告”形式的应用层协议便捷的实现了二者间通讯;通过PLC的高速脉冲串功能(PTO)驱动步进电机实现了探头精确定位;基于模块化思想的软硬件设计,使得系统更易于调试和维护。
