This design as the core, at89s52 SCM control with photoelectric sensors, LED digital tube, hardware position, etc, buzzer reusing the C programming language, and finally finished the design of motor speed tester. This paper expounds how to realize the motor speed by photoelectric sensor signal by monolithic integrated circuit at89s52 SCM, on the pulse signal processing, and then calculated by XianShiGuan digital display. Keywords: speed。該設(shè)計 以at89s52 單片機作為主控核心,與光電傳感器、 LED 數(shù)碼管、蜂鳴器等構(gòu)成硬件操作,再利用 C語言編程,最終完成電機轉(zhuǎn)速測定儀的設(shè)計。目錄 1 引言 .......................................................................................................................................... 1 2 系統(tǒng)實現(xiàn) ................................................................................................................................ 2 3 硬件設(shè)計 ................................................................................................................................ 2 方案實現(xiàn)原理 .......................................................................................................... 2 硬件設(shè)計框圖 .......................................................................................................... 3 硬件電路原理圖 ....................................................................... 錯誤 !未定義書簽。 槽型 光電傳感器 ITR8402 .................................................................................. 4 ISP 下載口 ................................................................................................................ 5 電源電路 .................................................................................................................... 5 脈沖信號完成電路 ................................................................................................ 5 單片機控制系統(tǒng) 電路 ........................................................................................... 6 超速報警電路 .......................................................................................................... 7 PCB 連線 .................................................................................................................. 8 4 程序設(shè)計 ................................................................................................................................ 8 程序設(shè)計思路 .......................................................................................................... 9 系統(tǒng)程序 ...................................................................................................................10 5 設(shè)計總結(jié) ..............................
