【正文】 超聲波測(cè)距儀的設(shè)計(jì)The design of a Silent WaveMeasure Distance摘 要隨著科技的發(fā)展，人們生活水平的提高，城市發(fā)展建設(shè)加快，城市給排水系統(tǒng)也有較大發(fā)展，其狀況不斷改善。但是，由于歷史原因合成時(shí)間住的許多不可預(yù)見因素，城市給排水系統(tǒng)，特別是排水系統(tǒng)往往落后于城市建設(shè)。因此，經(jīng)常出現(xiàn)開挖已經(jīng)建設(shè)好的建筑設(shè)施來改造排水系統(tǒng)的現(xiàn)象。城市污水給人們帶來了困擾，因此箱涵的排污疏通對(duì)大城市給排水系統(tǒng)污水處理，人們生活舒適顯得非常重要。而設(shè)計(jì)研制箱涵排水疏通移動(dòng)機(jī)器人的自動(dòng)控制系統(tǒng)，保證機(jī)器人在箱涵中自由排污疏通，是箱涵排污疏通機(jī)器人的設(shè)計(jì)研制的核心部分?？刂葡到y(tǒng)核心部分就是超聲波測(cè)距儀的研制。因此，設(shè)計(jì)好的超聲波測(cè)距儀就顯得非常重要了。本設(shè)計(jì)采用以 AT89C51 單片機(jī)為核心的低成本、高精度、微型化數(shù)字顯示超聲波測(cè)距儀的硬件電路和軟件設(shè)計(jì)方法。整個(gè)電路采用模塊化設(shè)計(jì)，由主程序、預(yù)置子程序、發(fā)射子程序、接收子程序、顯示子程序等模塊組成。各探頭的信號(hào)經(jīng)單片機(jī)綜合分析處理，實(shí)現(xiàn)超聲波測(cè)距儀的各種功能。在此基礎(chǔ)上設(shè)計(jì)了系統(tǒng)的總體方案，最后通過硬件和軟件實(shí)現(xiàn)了各個(gè)功能模塊。相關(guān)部分附有硬件電路圖、程序流程圖。經(jīng)實(shí)驗(yàn)證明，這套系統(tǒng)軟硬件設(shè)計(jì)合理、抗干擾能力強(qiáng)、實(shí)時(shí)性良好，經(jīng)過系統(tǒng)擴(kuò)展和升級(jí)，可以有效地解決汽車倒車、建筑施工工地以及一些工業(yè)現(xiàn)場(chǎng)的位置監(jiān)控。關(guān)鍵詞：AT89c51。 超聲波；測(cè)距AbstractWith the development of science and technology, the improvement of people39。s standard of living, speeding up the development and construction of the city. urban drainage system have greatly developed their situation is constantly improving. However, due to historical reasons many unpredictable factors in the synthesis of her time, the city drainage system. In particular drainage system often lags behind urban construction. Therefore, there are often good building excavation has been building facilities to upgrade the drainage system phenomenon. It brought to the city sewage, and it is clear to the city sewage and drainage culvert in the sewage treatment system. fort is very important to people39。s lives. Mobile robots designed to clear the drainage culvert and the automatic control system Free sewage culvert clear guarantee robot, the robot is designed to clear the culvert sewage to the core. Control System is the core ponent of the development of ultrasonic range finder. Therefore, it is very important to design a good ultrasonic range finder. At the core of the design using AT89C51 lowcost, high accuracy, Micro figures show that the ultrasonic range finder hardware and software design methods. Modular design of the whole circuit from the main program, pre subroutine fired subroutine receive subroutine. display subroutine modules form. SCM prehensive analysis of the probe signal processing, and the ultrasonic range finder function. On the basis of the overall system design, hardware and software by the end of each module. The research has led to the discovery that the software and hardware designing is justified, the antidisturbance petence is powerful and the realtime capability is satisfactory and by extension and upgrade, this system can resolve the problem of the car availably, building construction the position of the workplace and some industries spot supervision.Key words:AT89S52。 Silent Wave；Measure Distance 目 錄摘 要I AbstractII 緒論1 課題設(shè)計(jì)的目的及其意義1 超聲波測(cè)距儀的設(shè)計(jì)思路11 課題的方案設(shè)計(jì)與論證3 系統(tǒng)整體方案的設(shè)計(jì)3 系統(tǒng)整體方案的論證32 系統(tǒng)的硬件結(jié)構(gòu)設(shè)計(jì)4 單片機(jī)的功能特點(diǎn)及測(cè)距原理4 超聲波發(fā)射電路6 超聲波檢測(cè)接收電路7 超聲波測(cè)距系統(tǒng)的硬件電路設(shè)計(jì)73 系統(tǒng)軟件的設(shè)計(jì)9 超聲波測(cè)距儀的算法設(shè)計(jì)9 主程序流程圖10 超聲波發(fā)生子程序與超聲波接受中斷程序11 系統(tǒng)的軟硬件的調(diào)試12總 結(jié)13致 謝15參考文獻(xiàn)183
