1、河南理工大学毕业设计(论文)说明书摘要在工程实践中,经常会遇到各种需要测量转速的场合,测量转速的方法分为模拟式和数字式两种。模拟式采用测速发电机为检测元件,得到的信号是模拟量。数字式通常采用光电编码器,霍尔元件等为检测元件,得到的信号是脉冲信号。随着微型计算机的广泛应用,特别是高性能价格比的单片机的出现,转速测量普遍采用以单片机为核心的数字式测量方法。本文便是运用AT89C51单片机控制的智能化转速测量仪。电机在运行过程中,需要对其进行监控,转速是一个必不可少的一个参数。本系统就是对电机转速进行测量,并可以和PC
2、机进行通信,显示电机的转速,并观察电机运行的基本状况。本设计主要用AT89C51作为控制核心,由霍尔传感器、LED数码显像管、HIN232CPE电平转换、及RS232构成。详细介绍了单片机的测量转速系统及PC机与单片机之间的串行通讯。充分发挥了单片机的性能。本文重点是测量速度并显示在5位LED数码管上。其优点硬件是电路简单,软件功能完善,测量速度快、精度高、控制系统可靠,性价比较高等特点。关键字:MSC-51(单片机);转速;传感器1河南理工大学毕业设计(论文)说明书AbstractIntheprojectpra
