摘要
为了实时掌握与控制电传动装甲车辆在行驶和调试中所需要的数据,设计实现了基于CAN总线网络的显示控制终端。介绍了系统的硬件组成和软件设计流程,对设计中遇到的关键问题提出了有效的方法。设计实现终端电源的自动加载与关闭电路使其与车辆总开关联动,提高了系统的自动化。设计实现了基于Vxworks操作系统的实时多任务和图形显控界面等,提高了系统的实时性。
For handling and controlling the data that were need for electric drive armored vehicle to drive or debug,the display and control terminal based on CAN bus was designed.The paper introduces the compose of the hardware system,expounds the flow of software and resolves some key problems.The circuit of power＇s automatically turning on/off was realized.The real-time multitask based on Vxworks and graphics user interface by WindML are achieved.By these methods the system autoimmunization and real-time were improved.
