非接触测长测速仪的设计.doc

** PAGE ** 非接触测长测速仪的设计 摘要;在实际工业生产中,传统的接触式的长度速度测量方法,会因为机械磨损,尘埃等原因影响系统的正常工作。针对此不足本文以MCS-51系列单片机中的8051芯片为核心，采用光电传感器件，设计了一种新型的长度测量仪，具有长度测量，速度测量，数据显示，定时报警，等功能。 由于单片机价格低廉，可靠性高等特点，完全能满足新型非接触自动测长仪的要求。因此，以它作为微控制器，提高了整机的性能价格比。具有成本低，体积小，硬件电路简单，功能强，可靠性高等特点。加之运用了码拨盘输入、LED数字显示器，使整个装置的记数，显示，控制一气呵成，形成了集成度高，运行可靠，操作安全的智能化测量系统。 关键词：长度测量 速度测量 非接触 8051单片机 光电传感器 ABSTRACT In actual industrial production ,the traditional contact-type length measures the method, the meeting is worn and torn. Because of machinery ,such reasons as the dust ,etc, influence the normal work of the system. Direct against this insufficient this text Israel 8051 chips in the MCS-51 series one-chip computer are cores, design a kind of new-type length measuring apparatus. Length is measured , the data show , reporting to the police ,timing ,wait for the function. Have with low costs, mall, hardware circuit simple, the function is strong, the high characteristic of dependability .In addition application keyboard, LED display, make whole numeration of device , show, control and accomplish without any letup, it is high to form the integrated level, it is reliable to run, operate the intelligent control system of the security. Keywords: length measures Speed measures Don’t keep in touch 8051one-chip computer Photoelectric sensor 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc201412960 摘 要 PAGEREF _Toc201412960 \h I HYPERLINK \l _Toc201412961 ABSTRACT PAGEREF _Toc201412961 \h II HYPERLINK \l _Toc201412962 第一章 绪 论 PAGEREF _Toc201412962 \h - 1 - HYPERLINK \l _Toc201412963 1.1 引 言 PAGEREF _Toc201412963 \h - 1 - HYPERLINK \l _Toc201412964 1.2 非接触自动测长测速仪的发展概述 PAGEREF _Toc201412964 \h - 1 - HYPERLINK \l _Toc201412965 1.2.1 什么是非接触自动测量 PAGEREF _Toc201412965 \h - 1 - HYPERLINK \l _Toc201412966 1.2.2 非接触自动测长测速仪的应用前景 PAGEREF _Toc201412966 \h - 2 - HYPERLINK \l _Toc201412967 1.3 论文研究的目的和内容 PAGEREF _Toc201412967 \h - 2 - HYPERLINK \l _Toc201412968 第二章
