Development and Application of Information Verification and Transmission Experimental System based on Haiming Verification Code

In this paper, we study how to realize online simulation experiment based on Web in the experimental teaching of computer composition principle course. Taking the information verification and transmission experiment based on Haiming verification code as an example, this paper introduces the system development and design technology, and the design of experimental steps, so that students can master the processing process of information input, transcoding storage, verification encoding and decoding, and interference transmission in an interactive and immersive way, and visualize the internal information processing process of components. The idea of new teaching, new experiment and new future is realized through virtual simulation experiment teaching system.
