超聲波視力保護(hù)儀

1、【摘要】近年來，隨著科學(xué)技術(shù)的迅猛發(fā)展，超聲波傳感器無論是在生活還是工業(yè)中都扮演著舉足輕重的角色，對(duì)人類社會(huì)的進(jìn)步起著關(guān)鍵的作用。并且隨著工業(yè)控制領(lǐng)域要求的提高，單片機(jī)的性能和功能不斷提高，從最初的 8 位發(fā)展到如今的 32 位，基于 51單片機(jī)的教室燈光控制系統(tǒng)已經(jīng)成為現(xiàn)實(shí)，這極大地推動(dòng)了單片機(jī)和超聲波傳感器在生活中和工業(yè)中的普及和應(yīng)用。本文以“基于 51 單片機(jī)教室燈光控制系統(tǒng)設(shè)計(jì)”為研究對(duì)象，闡述了超聲波傳感器和 AT89C51

2、單片機(jī)的起源發(fā)展和原理、硬件整體結(jié)構(gòu)以及軟件設(shè)計(jì)，并著重介紹了“基于 51 單片機(jī)的超聲波視力保護(hù)儀”是如何設(shè)計(jì)以及實(shí)現(xiàn)的。 【關(guān)鍵詞】：AT89C51，LCD1602 液晶顯示器，超聲波傳感器，蜂鳴器，ABSTRACTIn recent years, with the rapid development of science and technology, ultrasonic sensors, whether in life or
