使用双处理器的汽车行驶记录仪设计

随着车联网技术的不断发展，为了提高客户的体验度及车贷功能安全，各个车厂争相推出带有各自特色的车载终端。由于功能的不断堆加，传统的单处理器设计方案已不再满足于现有车厂对设备的要求。随着功能越来越多，单处理器容易产生业务相互干扰，效率、实时性差等问题。针对于此，本设计在基于传统单处理器行驶记录仪基础上，采用双处理器方式进行设计，加快数据处理，提高系统的扩展空间，保证网络通信的实时性和并发性。

Vehicle Traveling Data Recorder Based on Dual-processor

With the continuous development of Internet of vehicles technology,in order to improve the customer experience and car loan function safety,each car factory is competing to launch the vehicle terminal with their own characteristics.As the function of the continu-ous heap,the traditional single processor design scheme is no longer satisfied with the existing car plant on the equipment requirements. As the functions are more and more,the single processor can easily generate the problems such as business of interference,efficiency,re-al-time and other issues.In view of this,based on the traditional single processor running recorder,the design uses dual-processor.The design can speed up the data processing and improve the system's extended space,ensure the real-time and concurrency of network com-munication.
