摘　　要：介绍了一种汽车智能组合仪表的设计,讨论了汽车智能仪表的结构和功能,分析了系统的软件设计。该仪表以基于ARM7的微控制器LPC2292微控制器为控制核心,采用源代码开放的嵌入式实时操作系统μC/OS-II作为应用程序的开发平台,实时显示和保存车速、发动机转速、水温、油位、总里程、子里程等车况参数,使汽车具有"黑匣子"功能。采用CAN总线建立通信网络。与传统汽车仪表相比,该仪表具有功能丰富、可靠性高、可视性好、通用性强等优点。A method of constituted the ear intellectual combined meter is introduced, and it＇s frame and function is discussed, and the system software is analyzed, LPC2292 Microcontroller is applied as its core and μC/OS-II is adopted and the meter possesses the function of displaying and saving the car＇s parameters such as the velocity of car, rotational speed of engine, temperature of wa- ter, the level of oil, total mileage and single mileage et on time, so that the car takes on the function of ＂Black Box＂. The system constitute communications networks based on CAN bus. The system have many merit such as abundance function, great reliability, and intuitionistic vision so forth.
