Abstract: This paper analyzes the deficiency of the existing electronic technology experimental hardware,and introduces the development of a kind of intelligent electronic technology experimental system with the function of fault point setting and monitoring.Through this experimental system,students can be reminded how to avoid making stupid mistakes,and improve the efficiency of experiments during the experiment.At the same time can cause students to attach importance to the learning of related knowledge points.Through real-time monitoring function,students can keep abreast of the progress of the students' experiment at any time and find out the problems in the course of the experiment.Practice has proved that through this new experimental system,students can be prompted to find circuit fault in the process to achieve practical ability,the ability to analyze the circuit,the use of instruments and other aspects of the ability to improve.
