摘要
 隨著社會(huì)信息化的發(fā)展，在現(xiàn)今的工控行業(yè)中，轉(zhuǎn)速的測量控制顯得越來越重要。尤其是對于彎管機(jī)的電機(jī)轉(zhuǎn)速控制要求更是嚴(yán)格，轉(zhuǎn)速過快或過慢都會(huì)影響到型材的質(zhì)量，使管材表面拉裂或起皺，所以只有轉(zhuǎn)速的高精度檢測才能得到高精度的控制系統(tǒng)。傳統(tǒng)的轉(zhuǎn)速測量方法較多，但都普遍存在測量精度較低、測試過程復(fù)雜等缺點(diǎn)。基于這點(diǎn)，本文介紹了旋轉(zhuǎn)編碼器的分類和測速原理，并且以旋轉(zhuǎn)編碼器結(jié)合單片機(jī)設(shè)計(jì)了一種具有轉(zhuǎn)速測量及控制功能的系統(tǒng)。結(jié)果表明，該測量儀運(yùn)行穩(wěn)定可靠，測量精度較高，完全滿足系統(tǒng)要求，其簡潔的電路設(shè)計(jì)和典型的控制方法具有一定的參考價(jià)值。

Abstract
 With the developing of information society, in today's industrial sector, rotary speed of measurement and control become increasingly important. Bending machine especially for the motor speed control is strict, too fast or too slow speed will affect the quality of profiles, so that pipe rupture or wrinkling the surface, so only the high-precision detection speed can be high-precision control system.There are many traditional methods of speed measurement, they are the lower measurement accuracy and preva lent, such as the shortcomings of the complexity of the testing process. For this reason, this article describes the classification of rotary encoder,velocimetry principle and rotary encoder to design a single-chip combination of a speed measurement and control systems.The results show that the measurement is stable, reliable operation，it has high measurement precision, fill the requirements of the system fully. Its simple circuit design and typical circuit control method has a certain reference value.
