摘要
针对机动车智能驾考系统的应用,设计了一种车载网关.网关采用基于ARMv7-M架构的STM32F107主处理器和CC2530无线协处理器组成双核处理器,辅以串口、CAN和以太网等外设接口电路共同搭建了硬件平台,并且以μC/OS-II操作系统、LwIP协议栈和ZigBee PRO协议栈为基础进行软件开发,能够实现车辆状态信息的采集和远程传输.实际应用表明,网关工作稳定、通用性高.
A vehicle gateway is designed for the intelligent electronic vehicle driving test system.The gateway applies the new ARMv7-M architecture STM32F107 as the main processor and the CC2530 as the wireless associa-tion processor to constitute a dual-core processor, and designs a variety of peripherals, such as serial, CAN and ethernet interface circuits, and develops application program based on μC/OS-II operating system, LwIP protocol stack and ZigBee PRO stack, to collect and transmit vehicle status information.The practical application shows that the gateway works stably and has high versatility.
