Abstract：In order to prevent the loaned important items from being forged and replaced, we created an algorithm of ultrasonic fingerprint recognizing and compiled an identification program.On this foundation,we developed a virtual instrument-- Industrial Computer to identify the ultrasonic anti-counterfeiting of ceramic using ultrasonic detection card.It is able to select varied envelope detection , adjust the gain nimbly and transmitted and received simultaneously while using this Industrial Computer.A great quantity experimental results show that the ceramic devices with the same appearance can be distinguished by the Industrial Computer.Then we studied the influence on the recognition results of the factors such as the rotation, displacement, different pressure on the probe and the change of the surface. The experimental results show that the technology can effectively identify the ceramic devices with the same appearance with the testing in different shape, material, pressure and boundary conditions.Our Industrial Computer established a well foundation to realize the intelligent, automatic, integrated and miniaturization of ultrasonic anti-counterfeiting identification system.
