基于C51单片机直流电机测速仪设计
摘 要：电机的转速是各类电机运行过程中的一个重要监测量，测速装置在电机
调速系统中占有非常重要的地位，特别是数字式测速仪在工业电机测速方面有独到的优势。本文介绍了一种基于C51单片机的光电传感器转速测量系统的设计。系统采用对射式光电传感器产生与齿轮相对应的脉冲信号，使用AT89C51单片机采样脉冲信号并计算每分钟内脉冲信号的数目，即电机对应的转速值，最终系统通过LCD实时显示电机的转速值。经过软硬件系统的搭建，分别通过Protues软件系统仿真实验和实际电路搭建检查实验。仿真实验表明本系统满足设计要求，并且结构简单、实用。整个直流电机测速系统在降低测速仪成本，提高测速稳定性及可靠性等方面有一定的应用价值。

Based On C51 SCM Single DC Motor Speedometer Design
ABSTRACT：Motor speed is all kinds of motor operation is an important process to monitor the amount of speed measuring device in the motor control system occupies a very important position, Especially the digital speedometer in the industrial motor speed has unique advantage. This paper describes a photoelectric sensor 51 SCM-based speed measurement system design. System uses a beam photoelectric sensor generates a pulse signal corresponding to the gear, the use of a sampling pulse signal AT89C51 SCM and calculating the pulse per minute, the number of signals that the speed of the motor corresponding to the value of the final system time through the LCD display the motor speed value.After a hardware and software system structures, respectively, through Protues software system to build the actual circuit simulation and experimental examination. Simulation results show that the system meets the design requirements, and the structure is simple and practical. DC Motor Speed entire system in reducing speedometer costs, improve reliability, speed stability and a certain application value.
