基于51單片機(jī)超聲波測距畢業(yè)論文-全文預(yù)覽
【正文】 nage 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。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，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)場的位置監(jiān)控。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。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。題 目：基于單片機(jī)的超聲波測距儀的設(shè)計(jì)與制作系 （部）：電氣與信息工程系專 業(yè) 班：電子信息工程姓 名：羅文杰學(xué) 號(hào)：指導(dǎo)教師：彭勇 2022 年 10 月 日目錄1 緒 論 .................................................................4 課題設(shè)計(jì)目的及意義 .............................................4 設(shè)計(jì)的目的 ...................................................4 設(shè)計(jì)的意義 ...................................................4 超聲波測距儀的設(shè)計(jì)思路 .........................................5 超聲波測距原理 .............................................5 超聲波測距儀原理框圖 .......................................5 課題設(shè)計(jì)的任務(wù)和要求 ...........................................62 課程的方案設(shè)計(jì)與論證 ..................................................7 系統(tǒng)整體方案的設(shè)計(jì) .............................................7 系統(tǒng)整體方案的論證 .............................................73 系統(tǒng)的硬件結(jié)構(gòu)設(shè)計(jì) ....................................................8 51 系列單片機(jī)的功能特點(diǎn)及測距原理 ...............................8 51 系列單片機(jī)的功能特點(diǎn) ......................................8 單片機(jī)實(shí)現(xiàn)測距原理 .........................................9 超聲波發(fā)射電路 ................................................10 超聲波檢測接收電路 ............................................11 超聲波測距系統(tǒng)的硬件電路設(shè)計(jì) ..................................114 系統(tǒng)軟件的設(shè)計(jì) .......................................................13 主程序流程圖 ..................................................14 系統(tǒng)的軟硬件的調(diào)試 ............................................175 總 結(jié) ...............................................................176 參考文獻(xiàn) .............................................................217 附 錄 ................................................................23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。城市污水給人們帶來了困擾，因此箱涵的排污疏通對大城市給排水系統(tǒng)污水處理，人們生活舒適顯得非常重要。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)字顯示超聲波測距儀的硬件電路和軟件設(shè)計(jì)方法。相關(guān)部分附有硬件電路圖、程序流程圖。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。展望未來，超聲波測距儀作為一種新型的非常重要有用的工具在各方面都將有很
