Research on Reliability of Multimedia Equipment in Universities Based on Big Data Analysis
With the development of education,multimedia teaching becomes the most common and most frequently used teaching mode in universities.Making full use of the running data of multimedia equipment,prolonging the working life of equipment and reducing the cost of equipment maintenance is always the concern of educational technology departments.Through the statistics and description of the multimedia equipment repair data of Weijin Road Campus of Tianjin University in the past six years,the equipment failure trend is generally mastered.SPSS analysis software is used to conduct linear regression for the data in 2020 and 2021,and the linear correlation between the total number of repairs and the annual service time and the overall service life of the equipment is analyzed.Based on the mean time between failures,the pure hardware repair reported in the past two years is analyzed by equipment type statistics,and the detailed verification process is given from concept introduction to derivation calculation.Based on the detailed analysis of the top five problems of software repair caused by non-hardware problems,three countermeasures and suggestions are put forward,i.e.,equipment renewal scientization,regular inspection standardization,and training methods diversification.
