摘　　要：压电晶体传感器在工程实践中占有重要地位,其静态特性标定实验也是测试技术课程的教学重点。目前传统的标定实验平台已经远远落后于现代测试技术的发展,制约了对现代测试技术的理解和掌握。因此,在传统的压电晶体传感器静态特性标定平台的基础上进行改造,利用虚拟仪器设计一套自动标定系统。利用现代测试的硬件与技术对传统的标定平台进行改造,使实验操作者避免复杂繁琐的操作,同时提高准确度。In engineering practice the piezoelectric crystal occupies an important position and its static property calibration experiment is the teaching emphasis of the measuring and testing technology courses. At present, the traditional calibration experiment platform has lagged a lot behind the development of modern testing technology, which has restricted our understanding and mastery of modern testing technology. The purpose of the project is mainly to make some transformations based on the traditional piezoelectric transducer static characteristics calibration platform by using the virtue instruments to design a set of automatic calibration system. Utilizing modern testing technology and hardware to transform the traditional calibration platform can avoid complicated operation and improve the accuracy of the experiment.
