【正文】 IIIAbstract Science and technology has been regarded as the core of development of productive forces, people want to create more advanced technology to improve the quality of people39。在半導(dǎo)體技術(shù)的支持下，本世紀(jì)相繼開發(fā)了半導(dǎo)體 熱電偶傳感器 、 PN 結(jié)溫度傳感器和集成溫度傳感器。它的體積小、質(zhì)量輕、價(jià)格便宜、為學(xué)習(xí)、應(yīng)用和開發(fā)提供了便利條件。 近幾年來微 型機(jī)快速發(fā)展，國外交直流系統(tǒng)數(shù)字化已經(jīng)達(dá)到實(shí)用階段由于以微處理器為核心的數(shù)字控制系統(tǒng)硬件電路的標(biāo)準(zhǔn)化程度高，制作成本低，且不受器件溫 度漂 移的 影 響，其 中單 片機(jī) 最 受歡迎 。其中用于自動控制系統(tǒng)的元件有許多種，但尤為單片機(jī)， PLC,計(jì)算機(jī)等在工業(yè)生產(chǎn)中有著舉足輕重的地位。 溫控電機(jī)調(diào)速 Temperature Control Motor Speed 題目名稱： 接口技術(shù) 院系名稱： 機(jī)電學(xué)院 2022 年 6 月 27 日 接口技術(shù) I 摘 要 科學(xué)技術(shù)一直被視為生產(chǎn)力發(fā)展的核心，人們希望創(chuàng)造更先進(jìn)的科技來提高人們的生活質(zhì)量。本文以單片機(jī)為例，詳細(xì)的介紹溫度傳感器是如何通過單片機(jī)來控制電機(jī)的速度。單 片機(jī) （ Single chip microputer） 微 型 計(jì) 算 機(jī) 簡 稱 單 片 機(jī) ， 是 典 型 的 嵌 入 式 微控制器（ Microcontroller Unit），常用英文字母的縮寫 MCU 表示單片機(jī)，單片機(jī)又稱單片微控制器 ，它不是完成某一個(gè)邏輯功能的 芯片 ，而是把一個(gè) 計(jì)算機(jī)系統(tǒng)集成到一個(gè)芯片上。同時(shí)，學(xué)習(xí)使用 單片機(jī) 是了解計(jì)算機(jī)原理與結(jié)構(gòu)的最佳選擇。與之相應(yīng)，根據(jù)波與物質(zhì)的相互作用規(guī) 律，相繼開發(fā)了聲學(xué)溫度傳感器、紅外傳感器和微波傳感器。s lives. Especially after the puter has, the people39。s internal heat, thus ensuring the normal operation of the work. In recent years, the rapid development of microputers, foreign Digital ACDC system has reached the practical stage due to the high degree of standardization of microprocessor core digital control system hardware circuit, low production costs, and the device is not affected by temperature drift, which SCM the most popular. SCM (Single chip microputer) singlechip microputers referred to, is a typical embedded microcontroller (Microcontroller Unit), monly used abbreviations in alphabetical said MCU MCU, microcontroller, also known as singlechip microcontroller, it is not pleted a certain logic chips , but to a puter system integrated into a chip. SCM consists of puting, controller, memory, input and output devices, the equivalent of a miniputer (minimum system), and a puter pared to the lack of a singlechip peripherals. Speaking in general terms: a chip has bee a puter. Its small size, light weight, cheap, learning, application and development of facilities provided. At the same time, learning to use a puter microcontroller is the best choice to understand the principle and structure. It was first to be used in industrial control. Temperature sensor from the early 17th century, people began to take advantage of the temperature measurement. In support of semiconductor technologies, this century have developed a semiconductor thermocouple sensor, PN junction temperature sensor and integrated temperature sensor. Correspondingly, based on the interaction of waves with matter of law, have developed acoustic temperature sensors, infrared sensors and microwave sensors. Temperature sensors are a variety of sensors in a wide variety of the most monly used, modern appearance temperature sensor was very small, so it is more widely used in various fields of production practices, but also for people39。 temperature control。 2 系統(tǒng)整體的選擇 2 溫度傳感器的選擇 3 DS1820 數(shù)字溫度傳感器 6 第五章 軟件的設(shè)計(jì) 15 第六章 結(jié)束語 15 第七章 參考文獻(xiàn) 而隨著溫控技術(shù)的發(fā)展，為了降低風(fēng)扇運(yùn)轉(zhuǎn)時(shí)的再引及節(jié)省能源等，溫度控制電機(jī)轉(zhuǎn)速這一方案越來越受到重視并廣泛的被應(yīng)有。根據(jù)被測溫度和預(yù)設(shè)溫度進(jìn)行比較從而調(diào)節(jié)電機(jī)的速度。并通過兩個(gè)按鍵改變預(yù)設(shè)溫度的大小，一個(gè)提高預(yù)設(shè)溫度，另一個(gè)降低預(yù)設(shè)溫度。 溫度傳感器的選擇 市面上賣的溫度傳感器各種各樣，但各有差別，要根據(jù)具體的需要進(jìn)行選擇。 調(diào)速方式 通過 8052 系列單片機(jī) AT89C52 作為控制器，采用 DALLAS 公司的溫度傳感器 DS1820 作為溫度采集元件，并通過一個(gè)反向驅(qū)動器 ULN2803 驅(qū)動電機(jī)的轉(zhuǎn)動。綜合考慮選擇此方案。耐磨耐碰，體積小，使用方便，封裝形式多樣，適用于各種狹小空間設(shè)備數(shù)字測溫和控制領(lǐng)域 。 RST/Vpd（ 9 腳）為復(fù)位輸入端口，外接電阻 電容 組成的復(fù)位
