Design And Implementation Of A New Experimental Teaching Platform For Analog Electronic Technology

With the rapid development of China’s economy,the teaching environment of domestic colleges and universities has been significantly improved,and the teaching facilities of colleges and universities are developing towards a more efficient and convenient direction.In the 21 st century,with the continuous development of electronic technology and more convenient social life,the experimental teaching facilities in Colleges and universities should also keep pace with the times.So far,many colleges and universities in China are still using old experimental teaching instruments.Some experimental teaching instruments are not only old,inconvenient to repair and maintain,but also large,occupying tense laboratory resources.When those old-fashioned experimental instruments leave the factory,the function of their circuit has been determined,so it is impossible to increase or decrease the experimental teaching content according to the actual teaching needs.Based on the above situation,it is more and more important to develop a new experimental teaching platform which is compact,high-performance and conducive to the experiment under the current epidemic conditions.This paper studies and designs a new experimental teaching platform of analog electronic technology.This paper extensively investigates the research status of analog electronic technology experimental teaching platform at home and abroad,puts forward a set of overall scheme of analog electronic technology experimental teaching platform based on embedded technology and foreign advanced "pocket laboratory" concept,and designs the hardware and software of the experimental platform.This paper expounds the design of the main control module,power module and human-computer interaction part of the circuit in detail,analyzes the software requirements of the main board and oscilloscope of the experimental platform,introduces the program logic of the whole software system based on the system function,and expounds the design of the display program in detail.Taking the user’s experience as the starting point,this paper fully considers the safety of the experiment,designs the basic experimental circuit of analog electronic technology,and reserves enough test points for the experimental circuit.This experimental platform pays attention to the compactness,expansibility and portability of the system.Its motherboard,experimental circuit and oscilloscope are designed independently.Finally,the experimental verification of the new analog electronic technology experimental teaching platform is carried out,and the functions of the main board and experimental circuit are tested through the design experiment,which verifies the feasibility and reliability of the new experimental platform designed in this paper,and provides a reference for the experimental platform design of other electronic technology courses.At the same time,this paper also points out the shortcomings and the future work of the experimental teaching platform.
