摘要:在工程實(shí)踐中,經(jīng)常會遇到各種需要測量轉(zhuǎn)速的場合,測量轉(zhuǎn)速的方法分為模擬式和數(shù)字式兩種。模擬式采用測速發(fā)電機(jī)為檢測元件,得到的信號是模擬量。數(shù)字式通常采用光電編碼器,霍爾元件等為檢測元件,得到的信號是脈沖信號。隨著微型計(jì)算機(jī)的廣泛應(yīng)用,特別是高性能價(jià)格比的單片機(jī)的出現(xiàn),轉(zhuǎn)速測量普遍采用以單片機(jī)為核心的數(shù)字式測量方法。 本文便是運(yùn)用MCS-51單片機(jī)控制的數(shù)字轉(zhuǎn)速計(jì)。本系統(tǒng)就是對電機(jī)轉(zhuǎn)速進(jìn)行測量,顯示電機(jī)的轉(zhuǎn)速。設(shè)計(jì)主要用MCS-51作為控制核心,由傳感器、LED數(shù)碼顯像管構(gòu)成。本文重點(diǎn)是測量速度并顯示在4位LED數(shù)碼管上。其優(yōu)點(diǎn)硬件是電路簡單,軟件功能完善,測量速度快、精度高、控制系統(tǒng)可靠,性價(jià)比較高等特點(diǎn)。 關(guān)鍵詞:51單片機(jī),光電傳感器,轉(zhuǎn)速計(jì)
Abstract: In the project practice, we will meet each kind to need frequently to survey the rotational speed the situation, the survey rotational speed method divides into the simulation type and the digital two kinds. The simulation type uses measured that the fast generator is the detecting element, obtains the signal simulates the quantity. Digital usually uses the electro-optical encoder, the Hall part and so on is the detecting element, obtains the signal is the signal impulse. Along with microcomputer's widespread application, specially high performance price compared to monolithic integrated circuit's appearance, the tachometric survey uses generally take the monolithic integrated circuit as the core digital measuring technique I graduated from the Design of the issue is control of the intelligent use of SCM speed measuring instrument. The system is the motor speed measurement,can communicate that the motor speed, and to observe the motor running the basic situation. The main design?。虲S-51 control as the core, by the Hall sensor, LED digital CRT. Give full play to the performance of the SCM. This paper is to measure the speed and displayed in five LED digital pipe. The advantage of a simple hardware and software capabilities improve, measuring speed, high precision and control system reliable, cost-effective and so on. Keywords: MCS-51;Photoelectric sensor;Tachometer
