基于CAN总线通讯混合动力挖掘机显示终端开发

Exploiture of Hybrid Excavator Display Terminal Based on CAN Bus

旨在设计一款适用于混合动力挖掘机上的新型显示终端。实现显示终端的CAN通讯数据采集、单片机数据处理及图形显示驱动功能。达到如传统显示终端的实时显示和故障报警功能,方便驾驶员直观观察,并且增加菜单设置功能和详细参数菜单显示功能方便研究人员了解详细参数。在英创嵌入式底板EM9161的平台上,通过在上位机使用eVC++编程,来实现系统各功能。调试结果表明,该显示终端能够满足新型混合动力挖掘机的需求。

A new display terminal for hybrid excavator was designed.The data collection based on CAN communication,data processing by SCM and graphical display microcontroller-driven function were achived.The realtime display of the traditional display terminals and failure alarm function to facilitate visual observation of the driver were reached.and increase The functions set detailed parameters by the menu and display capabilities for detailed parameters to facilitate researchers wer increased.Based on the embedded platform of EMTRONIX EM9161,the host computer used eVC＋＋programming to achieve the system functions.Debugging results showed that the display terminal can meet the needs of the new hybrid excavator.
