Design of Intelligent Measurement System for Fuel Consumption and Speed Based on Small RTOS51

介绍一种智能型油耗-转速测量系统的设计与实现。基于P89V51RD2单片机和SmallRTOS51嵌入式实时操作系统,该系统实现了对内燃机油耗、转速的自动测量、记录等工作。油耗测量采用重量法,转速测量使用磁电式转速传感器进行测量;使用单片机进行控制,包括信号的采集、计算、保存、通讯等方面的工作。该系统具有体积小,重量轻,功能全的特点。

This paper presents design and realization of an intelligent measurement system for fuel consumption and speed of IC engines. Based on P89V51RD2 SCM and Small RTOS51 embedded real-time operating system, the system can automatically measure and record the fuel consumption and engine speed. The fuel consumption and speed are measured respectively by weight method and magnetoelectric speed sensor. Signal acquisition, calculation, record, communication and so on are controlled by the SCM. This system features compact, light weight and multi-function.
