摘要
针对目现代液晶仪表开发技术的不足,开发设计了一种基于ARM的电动汽车仪表系统。系统采用模块化设计,包括信号采集,信号处理,数据显示三个模块。采用分层式软件结构,基于优先级调度方式调整运行秩序,使得逻辑简单易行,提高了系统的可靠性。硬件电路设计时采用多种抗干扰措施,增强了系统电磁兼容性。通过实验表明该系统能准确显示电动汽车参数,符合使用要求。
Aiming at the shortage of modern liquid crystal instrument development technology,an electric vehicle instrumentation system based on ARM is developed in this paper.The system adopts modular design that including three modules,such as signal acquisition,signal processing and data display.The hierarchical software structure is adopted to adjust the operation order based on the priority scheduling,which makes the logic simple and easy,and improves the reliability of the system.In the design of hardware circuit,the system takes various anti-interference measures to enhance the electromagnetic compatibility.The experimental results show that the system can display the parameters of electric vehicle accurately and meet the requirements.
