【摘要】 针对目前故障录波器的硬件配置、数据远传速度和稳定性等问题,设计并实现了一款新的以ARM和DSP为核心处理器,以μC/OS-II操作系统为软件平台的故障录波器。系统设计中,DSP担负密集型计算;ARM负责与DSP的通信、故障报告及与上位机的远传等,实现了对上位机通信、DSP通信及人机交互等多任务的实时控制与调度。对DSP与ARM的通信、故障数据上传的CAN协议进行了分析和设计。现场实验证明,系统运行稳定、可靠、高效。更多还原

【Abstract】 To solve problems on hardware configuration,remote data transmission speed and stability of the current fault recorder,a new fault recorder which takes ARM and DSP as core processor and μC/OS-Ⅱ OS as software platform is designed and implemented.DSP is used for high-speed data calculation while ARM is in charge of communicating with DSP,fault report and transferring fault data to host machine in the design.The real-time control and management of multi-tasks such as connection with the host machine,communication with DSP and HMI are completed.The CAN protocol,which is used for communicating between DSP and ARM and uploading the fault data,is studied and designed in detail.The actual experiments show that the system is stable,reliable,and efficient.更多还原
