自助网络学习平台中的最优内容推送系统设计与实现

Design and implementation of optimal content push system in self-service network learning platform

在物联网和嵌入式Linux内核环境下进行自助网络学习平台中的最优内容推送系统优化设计,提高自助网络学习平台的兼容性和应用可靠性。提出一种基于多线程总线开发的内容推送系统设计方法,进行系统的总体设计描述,在Visual DSP++4.5平台下建立自助网络学习平台内容推送系统的开发环境。系统的模块化设计主要包括了系统初始化程序、缓冲区设计、存储器设计、同步串口和CAN通信设计。在嵌入式程序加载模块进行内容推送程序加载,在物联网环境下构建嵌入式Linux内核进行自助网络学习平台的平台端口信息采集和可视化远程操作,提高内容推送的面向对象性和准确性。系统测试结果表明,该系统具有较好的稳健性和可靠性。

In the Internet of Things(IOT)and embedded Linux kernel environments,the optimization design of the opti?mal content push system in self?service network learning platform is carried out,which improves the compatibility and applica?tion reliability of the self?service network learning platform.A design method of content delivery system push based on the devel?opment of multi?threaded bus is put forward to describe the overall design of the system,and build the development environmentfor content push system of the selfservice network learning platform is in the Visual DSP++platform.The modular design of thesystem mainly includes system initialization program,buffer design,memory design,synchronization serial port and CAN communication design.The loading of the content push program is executed in the embedded program loading module.The embedded Linux kernel is built in IOT environment to carry out the port information acquisition and visualization remote operation ofthe selfservice network learning platform so as to improve the oriented object performance and accuracy of content push.Thesystem test results show that the system has high robustness and reliability.
