Research, Based On Signal Detection Course Of The Virtual Instrument Technology Demonstration And Experimental Methods

As we all know, experimental teaching is a very important part of higher education. Especially with the development of education system reform in colleges and universities, more and more professional teachers try to use advanced technology to integrate with the curriculum and develop a large number of experiments which combine with theoretical teaching. In this way, we can not only enhance the students'practical skills, but also make the entire teaching more fun, and greatly increase the teaching effect.Signal detection is an important specialized course in college. The reform of this course is necessary.In this thesis, a detailed study about the demonstration and experimental methods of signal detection course which were based on virtual instrument technology is carried out. The signal detection course and virtual instrument technology are integrated, the experimental system of the entire course is designed, the design ideas of the teaching experimental platform based on virtual instrument is investigated, and the theoretical study on the long-distance implementing scheme of signal detection virtual experiment is made; A simulation experiment system of signal detection (as a demonstration experiment system, achieve the validation and principles demonstration experiments) and the experiment system of practical application are developed, some simulation experiments and practical application experiments of signal detection are designed and implemented in the existing conditions (including temperature measuring,weighing experiments and online detection of motor).This experimental platform based on virtual instrument technology allows us to design and achieve a variety of experiments in a more flexible, convenient and funny way, and its cost is also greatly reduced. Through the course of this experiment, the students could feel more interest in this course and understand the theoretical knowledge on the textbook vividly, while also master a number of important practical applications of the course.
