Abstract： In special times， it is recommended to keep a social distance and protect the health of teachers and students， that has had a great impact on students' learning. Governments and schools at all levels paid great attention to online practical teaching and assessment. With the increasing maturity of technologies such as the Internet， cloud computing， and big data， it is easy to construct online defense assessments for practical courses. Discussed the current status of the graduation design online defense system， analyzed and designed the function and data model of the online defense system， designed a distributed software architecture system integrating Bootstrap， Springboot， MyBatis and other technologies， and described the key to the system technology. Finally， taking the development of the online video defense module of the system as an example， the development process of the system is de⁃ scribed in detail. Practice has proved that the system has the advantages of ease of use， high performance， scalability and good us⁃ er experience， which can improve the efficiency of the defense management of practical courses， help realize the sharing of teaching information resources， and achieve faster and better realization teaching supporting services.
