Experimental teaching is an important part of the science and engineering teaching. However, under the influence of "COVID-19" epidemic, it is difficult to carry out offline teaching which relies on actual experimental equipment. Therefore, based on the NI ELVIS Ⅲ physical machine and the analysisof the Internet + Hardware teaching mode, this paper puts forward a kind of false-or-true integration of real-time remote experiment teaching method. Taking the simulation experiment of analog electronic technology as an example, the experiment is designed to be carried out on remote teaching platform, and the theory teaching, simulation and operation results are analyzed through Multisim Live and Measurement Live. Practice show that since this experiment method is completely open, students can do experiments anytime anywhere to improve their practical and innovative abilities, hence the goal of "nonstop teaching and learning" can be achieved.
