摘要
以提升用户体验感和仿真平台性能为目标,构建面向用户体验的云端协作仿真平台。运用嵌入式技术和物联网技术构建由上、下位机组成的云端协作仿真平台,平台下位机利用嵌入式控制芯片ATMEGA16L完成平台的交叉编译和总线控制,经局域网通信和高速数据传输协议完成总线调度;平台上位机通过AD模块采集并分析信息,利用以Intel80C196KC单片机为核心的直接控制器,实现平台的云端协作仿真控制,并采用基于用户兴趣的资源推荐模型,依据用户兴趣的扩散步骤,为用户推荐感兴趣资源,通过显示屏完成与用户的人机交互。测试结果表明,上述平台的用户推荐资源准确率和召回率更优,可更好满足用户需求;不同时刻下平台的控制能耗低,且不同平台处理核数和并行应用数量下的资源调度时间少,平台性能好。
This article aims to improve user experience and simulation platform performance,and constructs a cloud based collaborative simulation platform for user experience.Firstly,we used the embedded technology and Inter-net of things technology to build a cloud collaborative simulation platform composed of upper and lower computers.Then,the lower computers used the embedded control chip ATMEGA16L to complete the cross compilation and bus control,thus completing the main line scheduling through LAN communication and high-speed data transmission pro-tocol.Meanwhile,the upper computer collected and analyzed the information through AD module,and then used the direct controller taking Intel 80C196KC as the core to implement the cloud collaborative simulation control of plaform,According to the diffusion steps of user interest,we used a resource recommendation model based on user in-terest to recommend the interesting resource for users.Finally,we completed the human-computer interaction with us-ers through the display screen.The test result proves that the accuracy and recall of user recommended resource are better,which can meet the users'demands.The plaform always has lower control energy consumption at different times and less resource scheduling time under the number of processing cores and the number of parallel apps of dif-ferent platforms.Therefore,the performance of platform is good.
