【正文】 有效,數(shù)碼顯示屏顯示搶答時(shí)間倒計(jì)時(shí)和選手號(hào),在最后五秒揚(yáng)聲器發(fā)生提示。在后臺(tái)主持人可以修改,搶答時(shí)間和選手回答問(wèn)題的時(shí)間設(shè)置,如原始狀態(tài)下?lián)尨饡r(shí)間為15s,回答問(wèn)題時(shí)間為30s。 課題研究的內(nèi)容本系統(tǒng)采用模塊化設(shè)計(jì)智能搶答器,在搶答比賽中廣泛應(yīng)用,各組分別有一個(gè)搶答按鈕。初步掌握多功能搶答器的調(diào)整及測(cè)試方法。 選題的目的和意義通過(guò)這次課程設(shè)計(jì),了解簡(jiǎn)單多功能數(shù)字電路搶答器的組成原理,初步掌握數(shù)字電路搶答器的調(diào)整及測(cè)試方法,提高思考能力和實(shí)踐能力。優(yōu)先編碼電路、鎖存器、譯碼電路將參賽隊(duì)的輸入信號(hào)在顯示器上輸出;用控制電路和主持人開關(guān)啟動(dòng)報(bào)警電路,以上兩部分組成主體電路。因此,我選擇簡(jiǎn)易邏輯數(shù)字搶答器這一課題。隨著科技的發(fā)展,現(xiàn)在的搶答器有著數(shù)字化,智能化的方向發(fā)展,這就必然提高了搶答器的成本。早期的搶答器只由幾個(gè)三極管、可控硅、發(fā)光管等組成,能通過(guò)發(fā)光管的指示辯認(rèn)出選手號(hào)碼。比賽中為了準(zhǔn)確、公正、直觀地判斷出第一搶答者,這就要有一種搶答設(shè)備作為裁判員,這就必然離不開搶答器。 Starting the warning circuit with the control circuit and host39。通過(guò)定時(shí)電路和譯碼電路將秒脈沖產(chǎn)生的信號(hào)在顯示器上輸出實(shí)現(xiàn)計(jì)時(shí)功能,構(gòu)成擴(kuò)展電路。數(shù)字搶答器由主體電路與擴(kuò)展電路組成。但搶答器的使用頻率較低,且有的要么制作復(fù)雜,要么可靠性低,減少興致。數(shù)字搶答器的研究、設(shè)計(jì)姓 名  學(xué) 號(hào) 年 級(jí) 專 業(yè) 通信工程 系?。ㄔ海? 信息學(xué)院 指導(dǎo)教師 摘 要隨著科學(xué)技術(shù)的不斷發(fā)展,促使人們學(xué)科學(xué)、學(xué)技術(shù)、學(xué)知識(shí)的手段多種多樣。搶答器作為一種工具,已廣泛應(yīng)用于各種智力和知識(shí)競(jìng)賽場(chǎng)合。做為一個(gè)單位若專購(gòu)一臺(tái)搶答器雖然在經(jīng)濟(jì)上可以承受,但每年使用的次數(shù)極少,往往因長(zhǎng)期存放使(電子器件的)搶答器損壞,再購(gòu)置的麻煩和及時(shí)性就會(huì)影響活動(dòng)的開展,因此設(shè)計(jì)了本搶答器。優(yōu)先編碼電路、鎖存器、譯碼電路將參賽隊(duì)的輸入信號(hào)在顯示器上輸出;用控制電路和主持人開關(guān)啟動(dòng)報(bào)警電路,以上兩部分組成主體電路。關(guān)鍵字:搶答電路 定時(shí)電路 報(bào)警電路 時(shí)序控制24ABSTARCTWith the continuous development of science and technology, promote learning science, science and technology, knowledge of the variety of means. With a tool for Qiangda, which has been widely used in all kinds of intelligence and knowledge contests occasions. But Qiangda is used for lower frequency, and some production plex or low reliability, and reduced interest. As a unit, if the purchase is a Qiangda .Although the economy can bear, each year the number is extremely small, because of the longterm storage (electronic devices) Qiangda for damage to the purchase of the trouble and timeliness of activities, The development will be affected, so this Qiangda is designed .The figure vies for the answering device by the subject circuit and expands the circuit to make up . Have priority in code circuit , latch , decipher circuit and export the input signal of the entrant team on the display。s switch, two the abovementioned parts make up the subject circuit. Through timing circuit and decipher second signal function while outputs and realizes counting on the displaying that pulse produce circuit, form and expand the circuit.Keywords: Vie for answering the circuit Timing circuit Warning circuitTime sequence controlling目錄摘要……………………………………………………………………ⅠAbstract…………………………………………………………………Ⅱ1緒論……………………………………………………………………Ⅲ……………………………………………1………………………………………………1…………………………………………………1…………………………………………………2……………………………………32搶答器的系統(tǒng)概述…………………………………………………4…………………………………………4…………………………………………4…………………………………………5………………………………………………5………………………………………………73搶答器的電路設(shè)計(jì)…………………………………………………7…………………………………………………7…………………………………………84搶答器的單元電路設(shè)計(jì)……………………………………………10……………………………………10………………………………………12…………………………………………13……………………………………14…………………………………………15………………………………………………17……………………………………………………………175總結(jié)與展望…………………………………………………………18謝辭……………………………………………………………………2
