【正文】 的實(shí)現(xiàn)我的設(shè)計(jì);而在輸 入設(shè)備中,相比較 IC 卡和條形碼掃描,我個(gè)人認(rèn)為指紋識(shí)別更加方便實(shí)用,而且所用資源比較少,性價(jià)比更高,所以選擇指紋識(shí)別作為本次實(shí)驗(yàn)的方案;而在輸出設(shè)備中,我認(rèn)為繼電器方案能夠更加明顯的顯示我的設(shè)計(jì),更加容易的實(shí)現(xiàn),綜上所述,我的方案定為這樣的。電磁鎖的驅(qū)動(dòng)功率需要 20W 以上,可以采用 20V 直流電源,產(chǎn)生 1A 的驅(qū)動(dòng)電流,為加強(qiáng)驅(qū)動(dòng)功率,采用二級(jí)直流放大。 非接觸 IC 卡電子存包柜方案 以使用者所持 IC 卡(即射頻卡)作為寄存的憑證;當(dāng)使用者進(jìn)行存物操作時(shí),須先按一下操作鍵盤中的“存”鍵再刷卡(即讓寄存柜讀取卡號(hào)),寄存柜先識(shí)別是否為該場(chǎng)所的 IC 卡,若不 是則拒絕存物;若是,機(jī)器會(huì)把該卡號(hào)與分配給使用者使用的寄存箱的箱號(hào)結(jié)合起來(lái),并將信息自動(dòng)記錄下,同時(shí)自動(dòng)打開該箱,供使用者存物,存完后自己關(guān)好箱門;取物時(shí),只需須先按一下操作鍵盤中的“取”鍵再刷卡,寄存柜將讀取的卡號(hào)與先前記錄下的進(jìn)行比對(duì),正確后才會(huì)打開該箱供使用者取物(同時(shí)機(jī)器會(huì)自動(dòng)記錄當(dāng)時(shí)的時(shí)間、卡號(hào)以備查詢) 優(yōu)點(diǎn):識(shí)別度高,系統(tǒng)穩(wěn)定, 缺點(diǎn): IC 卡不易攜帶,而且會(huì)出現(xiàn)消磁等問(wèn)題,所以不適于本次設(shè)計(jì)。 第三部分:執(zhí)行機(jī)構(gòu)部分。 2. 2 輸入端方案的選擇 機(jī)設(shè)條碼式電子存包柜 方案 存物時(shí):按“存”鍵,寄存柜自動(dòng)打印一張密碼條,機(jī)器語(yǔ)音提示:“請(qǐng)取密碼條”。后面的零電阻及其電源、地分成不同的幾路是為減少電磁干擾設(shè)置的。控制功能弱,常需要與單片機(jī)或 FPGA (現(xiàn)場(chǎng)可編程門陣列 )結(jié)合 , 來(lái)實(shí)現(xiàn)人機(jī)交互 。因此,研 制出一種能自動(dòng)存包的裝置有很重大的意義,我所研究的就是這方面的課題。從實(shí)現(xiàn)方式和功能上來(lái)看,電子存包柜屬于電子專用設(shè)備。 (4)指令系統(tǒng)突出控制功能。 2.第二階段 —— 單片機(jī)的完善階段 (1978 年一 1982 年 )。國(guó)際上逐漸采用 MCU(MicroControllerUnit” )來(lái)代替,形成了單片機(jī)界公認(rèn)的、最終統(tǒng)一的名詞。 關(guān)鍵詞 :自動(dòng)存包柜 ,單片機(jī) ,指紋識(shí)別器 李少鵬:基于單片機(jī)的自動(dòng)存包系統(tǒng)設(shè)計(jì) II Based on single chip microputer automatic package design Abstract In recent years, with the improvement of living standards, people for social consumer goods quality and quantity requirements are to increase gradually. In order to better service for the general customers, in some stores, movie theaters, supermarkets public Settings are to be put automatically usually bag ark, it is functional practical, simple operation, safe and reliable, antijamming strong sexual characteristics. Domestic deposit automatic control system are introduced in detail in this paper the development of the status quo, problems faced in the development of. And introduces in detail the system adopts single chip microputer controller, can simultaneously manage multiple pack ark. Cupboard door lock controlled by relay, when customers need to save package, will be allowed to save package before the ark according to the open button, need customer to the system input fingerprint, and then through the relay to open the door (with lighting), customers can save package, and the cupboard door must be closed. When customers need to pick up package, as long as before the input fingerprint should be placed on the fingerprint recognizer, fingerprint recognizer collecting to the fingerprint information and output the corresponding high and low level signal to the microcontroller, the system is password consistent, signal out of the box to the relay Key words: Automatic Storage Bag, Microcontroller, Fingerprint recognizer。華科學(xué)院本科畢業(yè)設(shè)計(jì)(論文) I 基于單片機(jī)的自動(dòng)存包系統(tǒng)設(shè)計(jì) 摘 要 近年來(lái),隨著生活水平的提高,人們對(duì)于社會(huì)消費(fèi)品的質(zhì)量和數(shù)量的要求也在逐漸增加。 華科學(xué)院本科畢業(yè)設(shè)計(jì)(論文) I III 目 錄 摘 要 ................................................................................................................................................
