摘要
针对车企的云平台开发基础薄弱和大数据应用能力差的问题,为满足电动汽车车辆安全、预测性维护、车辆优化设计等多维度多层次数据应用需求,文章提出了一种基于车载终端的边缘计算的实现方案,设计了以Arm Cortex-A7和EMMC为计算核心的车载终端硬件平台,基于嵌入式Linux系统和Socket虚拟技术开发了满足多数据应用同时运行的边缘计算平台,并设计了边缘计算数据应用的软件开发通用框架。数据应用实例验证结果表明,该方案在低带宽、低延时应用中具有优势。
Car enterprises has weak foundation of the cloud platform development and poor application ability of big data.In order to meet the requirements of multi-dimensional and multi-level data application for electric vehicle safety,predictive maintenance and vehicle design optimization,an implementation scheme based on vehicle terminal edge computing was proposed.A vehicle telematics box hardware platform with Arm Cortex-A7 and EMMC as computing core was designed.Based on embedded Linux system and Socket virtualization technology,an edge computing platform satisfied simultaneous operation of multi-data applications was presented and a software general framework for edge computing data application was designed.The data application example shows that the scheme is low bandwidth and low latency.
