用于轨道车辆微控制器的组网固件更新组件的设计

Rail Vehicle Microcontroller Design of Networking Firmware Update Component

轨道车辆微控制器产品在开发、生产、交付、维护等环节,会遇到各种需要通过IAP对微控制器进行固件更新的应用场景,可以说IAP贯穿一款产品的整个生命周期。介绍嵌入式操作系统MicroLite的组网固件更新组件,该组件支持以太网、CAN总线通信接口对多个微控制器嵌入式设备实现组网升级,已在轨道车辆批量装车运行,效果良好。

In the development,production,delivery,maintenance of rail vehicle microcontroller products,we will encounter various application scenarios that need to upgrade the firmware of microcontrollers through IAP,and it can be said that IAP runs through the whole life cycle of a product.This paper introduces the networking firmware update component of embedded operating system MicroLite,which supports Ethernet and CAN bus communication interface for multiple microcontroller embedded devices to achieve networking update,and has been run in rail vehicles with good results.
