基于FPGA的工程机械CAN总线技术研究

CAN Bus Technology Research of Construction Machinery Based on FPGA

介绍了一种利用FPGA实现工程机械CAN总线的设计思路。在Altera的Cyclone系列的FPGA芯片上实现了NIOS、Flash、SDRAM和CAN控制器核的系统设计,并在NIOS IDE中完成了系统软件设计,通过USB-CAN工具测试该CAN核具有良好的性能,与EPEC2024控制器和ST104显示器等通信表现出了优异的可靠性和稳定性。

The thesis introduces a method to realize construction machinery CAN bus.In the Altera’s cyclone series FPGA,designed and realized the system of NIOS,flash,SDRAM and CAN IP core.Besides,in the software of NIOS IDE,the author finished the system software.By the experiment of USB-CAN,this CAN IP Core performed excellence.In the communication of EPEC2024 controller and ST104 display,performed outstanding reliability and stability.
