摘要
针对传统车载激光测距设备采用串口通信协议难以满足系统实时性、多主方式的要求,介绍了基于FPGA的串口/CAN转换模块可配置化设计,该设计支持多主工作方式,相比较于基于单片机的串口/CAN转换设计,其数据通信实时性强,支持在线参数配置和数据并行处理,支持多路CAN总线,且优先级相同,保证通信的实时性和准确性。测试结果表明该设计提高了系统通信的可靠性和灵活性。
It is difficult to meet the real-time and multi-master requirements of the system by using the serial communication protocol for the traditional vehicle-mounted laster ranging device,a configurable design of serial-port/CAN conversion module based on FPGA is introduced,this design supports multimaster work,compared with the design of serial-port/CAN conversion based on single-chip microcomputer,its data communication is strong in real-time,supports online parameter configuration,data parallel processing and multi-channel CAN bus owning the same priority,and ensures the real-time and accuracy of communication.Test results show that the design improves the reliability and flexibility of system communication.
