Personalized Information Service System of Smart Library Based on Multimedia Network Technology

Abstract

Scientific and objective book quality evaluation and research on the value of books in the smart library are conducive to improving the reading needs of readers. However, it is difficult to obtain the important coefficient of the subjective and objective weight of the personalized information service index of the smart library at present, which has the problem of poor system performance. Therefore, a personalized information service system of the smart library based on multimedia network technology is designed. In multimedia network technology, the data collector module, data retriever module, and data memory module of the system hardware are designed. The Ethernet interface is connected through three buses to ensure the efficient operation of the system; according to the hardware, the software flow is introduced, which is divided into UI layer, logical business layer, and data access layer. On this basis, the application program is designed, all operation instructions follow the association rules, and the single-chip microcomputer is connected with the voice chip through the SPI serial port, so as to complete the design of the personalized information service system of the smart library. The experimental results show that the average absolute deviation of the designed system is small, the comprehensive performance is strong, and the update delay is kept within 0.6 s, which can improve the work efficiency.

Analysis on Network Information Security Protection Technology of Intelligent Terminal Power Monitoring System of Substation under the Support of Multimodal Multimedia Information

“…Te equipment status in the substation is observed through intelligent image detection and structured analysis, and the instrument panel reading value, disconnector status, intermittent circuit breaker power switch indicator status and control box marking status are identifed [20]. If the copy exceeds the limit, warning can be issued, and the identifcation conclusion can be uploaded to the information integration platform through the DL/T860 agreement.…”
