单片微机控制汽车数显智能仪表设计

Design of Auto Digital lntellectual Instrument Controlled by Single-chip Microcomputer

以单片机控制的汽车数字显示智能仪表,具有多通道、多功能、多智能、高精度优势.特别是对汽车总里程的处理,不但象短程里程一样,采取了电脑累积与电子数字显示,而且采用了汽车熄火掉电,电脑记忆保存总里程的新尝试.从而取代了汽车常规的以微电机驱动机械数字轮的记忆与显示方法,使本设计实现了汽车数显仪表的全盘电子化.

The auto intellectual and digital displaying instrument controlled by the single-chip microprocessor has many advantages of multi-channel, multi-function and comprehensive, intellectuals as well as its high precision. Especially, for treating the auto total mileage as the same as for the short distance mileage, it not only adopts the function of computer accumulation and electronic digital display,but also makes an effort to memory the total mileage when the car ignition is switched off. So, the conventional mechanical numerical drum type instrument is replaced and the fullly elec-tronozed type is realized.
