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 environment for content push system of the self-service network learning platform is in the Visual DSP ++ platform. The modular design of the system mainly includes system initialization program,buffer design,memory design,synchronization serial port and CAN com-munication design. The loading of the content push program is executed in the embedded program loading module. The embed-ded Linux kernel is built in IOT environment to carry out the port information acquisition and visualization remote operation of the self-service network learning platform so as to improve the oriented object performance and accuracy of content push. The system test results show that the system has high robustness and reliability.%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.
