单片机控制的发动机转速智能检测

The Single-chip Microcomputer Controlling Rotational Speed Of Diesel Engine Intelligent Detecting

本文是基于与一汽汽研联合研制的机动车柴油类发动机数字转速表，整个系统由8751单片机控制，速度检测传感器采用电阻应变式传感器（已申报专利）。系统整体设计力求抗误喷油干扰、低功耗、微型化及智能化。文中系统阐述了该仪表的软、硬件设计思想，对测试结果及误差也进行了一定的分析。

This paper is on the basis of digital rotationa1 speed instrument of diesel engine researched by the research institute of first plant of automobile manufactured and I. The whole system controlled by 8751 single-chip microcomputer, the speed detected by the resistance-strain f 5nsor (it tias been applied for patent). The ensemble desisn of system is better in resisting disturbance c ! diesel spraye by mistake and power low-loss and miniaturization and intelligencize. The software design and hardware design of this instrument are systematic expounded in this paper. And the result detect6d and erro are analytal in it, too.
