Dual Redundant CAN Data Acquisition Device Based on HWD32F429
针对控制器局域网(controller area network,CAN)总线在嵌入式软件领域中的应用问题,设计一种基于HWD32F429 的双冗余CAN数据采集装置.该装置采用国产芯片HWD32F429 作为核心处理器,主要外设包括CAN总线接口芯片 JM3062W、FLASH 存储芯片 SM25QH256M、温度传感器 NST175 和串口收发器 GLb2582C,并适配FreeRTOS实时操作系统作为数据采集装置的软件平台,完成 CAN总线数据收发与处理,对运行系统中发生的错误通过指示灯进行提示与预警,并通过点名式的软件设计降低了因数据节点增多导致的节点故障率和节点数据丢失率.结果表明,该装置可用于可靠性要求高的军用车辆和船舶监控系统.
Aiming at the application of controller area network(CAN)bus in the field of embedded software,a dual redundant CAN data acquisition device based on HWD32F429 is designed.The Device uses a domestic chip HWD32F429 as its core processor,and its main peripherals include a CAN-bus interface chip JM3062W,a FLASH memory chip SM25QH256M,a temperature sensor NST175,and a serial transceiver GLb2582C.It adapts FreeRTOS real-time operating system as the software platform of the data acquisition device,completes the data transmission and processing of CAN bus,and prompts and warns the errors in the running system through the indicator light.The node failure rate and node data loss rate caused by the increase of data nodes are reduced by the design of the software.The results show that the device can be used in military vehicle and ship monitoring systems with high reliability requirements.
