Problems solved by technology

[0004] In 2012, Kiyoshi Matsumoto disclosed the "Ultrasonic Measurement Method and Ultrasonic Measurement System" in the invention patent CN201210017770.8. This method uses a pair of transmitting and receiving ultrasonic sensors distributed on the upper and lower sides of the material to be tested, and the ultrasonic waves are used between the two sensors. The thickness of the coating material can be obtained by the transmission between them; however, this method cannot measure the residual stress, and the measurement system is not portable
In 2009, Wang Zicheng and others disclosed a "portable multi-channel ultrasonic diffraction time-of-flight detection device" in the i

Abstract

The invention provides a multifunctional portable ultrasonic measuring instrument based on PCI/PCIe and a using method, and belongs to the technical field of ultrasonic measuring systems. The ultrasonic measuring instrument is composed of an ultrasonic transmitting and receiving device, a high-speed digitizer, a multiplexer, a DSP data processing module, an ultrasonic sensor, an electromagnetic ultrasonic adapter, an industrial portable computer and the like, and has two ultrasonic transmitting and receiving functions including a multi-channel piezoelectric ultrasonic transmitting and receiving mode and a single-channel electromagnetic ultrasonic self-transmitting and self-receiving mode. The ultrasonic measuring instrument is compact in structure and good in portability, and the wall thickness of a part and the size and distribution of residual stress are rapidly obtained; the electromagnetic ultrasonic sensor can be excited, so that the problem of poor measurement precision caused by non-uniform coupling state of the traditional piezoelectric ultrasonic sensor is solved; the data processing module based on hardware realizes processing and calculation of high-throughput ultrasonic signals, and meets the requirement for rapid and accurate measurement of the wall thickness and residual stress of parts in a manufacturing site environment.
