(duì)較低。相比較電子保險(xiǎn)箱具有操作簡(jiǎn)單，安全性高，易攜帶，不易破裂等優(yōu)點(diǎn)。3.紅外編碼和發(fā)送模塊：方案一：專用芯片解決方案。特殊的紅外編碼芯片種類很多，例如日本三菱公司的M50426AP、PT2262、BL9148、ZD6631等，這類芯片一般將載波振蕩，編碼傳輸兩種功能合二為一，具有很強(qiáng)的抗干擾能力，外圍電路簡(jiǎn)單，使用起來(lái)很方便，而且成本很低，大多數(shù)遙控設(shè)備都使用這種專用芯片。但是，ASIC具有致命的弱點(diǎn)，那就是專用芯片的應(yīng)用靈活性差，其內(nèi)部代碼已被固定，無(wú)法修改內(nèi)部數(shù)據(jù)，不適用于經(jīng)常需要更改的數(shù)據(jù)傳輸，而且專用芯片幾乎都是定向指令碼的遠(yuǎn)程控制方式，傳輸效率低，同時(shí)大多數(shù)專用芯片的內(nèi)部代碼和技術(shù)數(shù)據(jù)均已公開(kāi)，安全性大大降低。方案二：微處理器和專用芯片的組合解決方案，程序由微處理器和專用編碼芯片PT2262組合完成編碼，載波的產(chǎn)生由MC4011和38kHz晶體振蕩器共同構(gòu)成，振蕩形成生38kHz方波。PT2262的功能是使數(shù)據(jù)以6位數(shù)據(jù)位并行傳輸?shù)姆绞?。PT2262將6位并行數(shù)據(jù)轉(zhuǎn)換為串行數(shù)據(jù)，減輕了編程負(fù)擔(dān)，并加快了傳輸速度。A6/D0、A11/D5～PT2262共有6個(gè)復(fù)用端口用于數(shù)據(jù)端口，PT2262自動(dòng)將微處理器6個(gè)數(shù)據(jù)從Dout端口發(fā)送為串行數(shù)據(jù)。該方案可以計(jì)算出密碼的數(shù)量，編碼和解碼算法以及同步信號(hào)，大大提高了數(shù)據(jù)的安全性。缺點(diǎn)是使用PT2262會(huì)增加硬件成本和電路復(fù)雜性。該程序使用微處理器的I/O端口直接生成38KHz調(diào)制波，該波驅(qū)動(dòng)紅外發(fā)射二極管傳輸紅外數(shù)據(jù)。CPU計(jì)時(shí)器或軟件編程生成的38KHz方波，紅外編碼工作由該軟件完成。因此，紅外編碼方案可以任意設(shè)計(jì)，外部?jī)H需簡(jiǎn)單的硬件電路，大大降低了電路的復(fù)雜度，有利于降低成本，減小體積。由于使用軟件編碼方案，占用CPU時(shí)間CPU的處理速度受到一定的影響，但是，由于遠(yuǎn)程控制的功能與單個(gè)系統(tǒng)相比，處理任務(wù)相對(duì)較小，對(duì)CPU處理效率的影響就是會(huì)增加編程軟件的負(fù)擔(dān)。相比之下，方案二不僅可以滿足主題的要求，電路非常簡(jiǎn)單，硬件成本非常低，僅增加了編程軟件的負(fù)擔(dān)，使得紅外編碼非常靈活。4.系統(tǒng)軟件開(kāi)發(fā)環(huán)境：Keilc51是由51系列兼容MCUC語(yǔ)言軟件開(kāi)發(fā)系統(tǒng)公司生產(chǎn)的keil軟件，與匯編語(yǔ)言相比，C語(yǔ)言在功能、結(jié)構(gòu)、可讀性、維護(hù)性上具有明顯的優(yōu)勢(shì)，易于使用。開(kāi)始使用匯編語(yǔ)言之后再使用C語(yǔ)言進(jìn)行開(kāi)發(fā)是，會(huì)有更加深刻的體會(huì)。Keilc51軟件提供了豐富的庫(kù)功能以及強(qiáng)大的集成開(kāi)發(fā)和調(diào)試工具。另一個(gè)重要的點(diǎn)就是，只要看一下編譯器生成的匯編代碼，您就可以體驗(yàn)到C51Keil生成的目標(biāo)代碼效率非常高，大多數(shù)語(yǔ)句生成的匯編代碼非常緊湊，易于了解。在開(kāi)發(fā)大型軟件時(shí)可以更好地體現(xiàn)高級(jí)語(yǔ)言的優(yōu)勢(shì)。C51工具包的整體結(jié)構(gòu)，其中uVision和C51分別是用于WindowsIshell和Dos的集成開(kāi)發(fā)環(huán)境（IDE），用戶可以完成編輯，編譯，鏈接，調(diào)試，仿真和其他開(kāi)發(fā)過(guò)程。開(kāi)發(fā)人員可以使用IDE本身或其他編輯器來(lái)編輯C語(yǔ)言程序或程序集源文件。然后由C51和A51編譯器編譯以生成目標(biāo)文件（.OBJ）。目標(biāo)文件可以由LIB51庫(kù)文件創(chuàng)建，也可以與具有L51連接的庫(kù)文件一起創(chuàng)建，以生成絕對(duì)目標(biāo)文件（.ABS）。ABS文件由OH51轉(zhuǎn)換為標(biāo)準(zhǔn)的十六進(jìn)制文件，用于調(diào)試dScope51或tScope51，也用于源代碼的調(diào)試，模擬器用于直接在目標(biāo)板上進(jìn)行調(diào)試，也可以直接寫(xiě)入程序存儲(chǔ)器。5.紅外數(shù)據(jù)接收模塊：接收部分由單片機(jī)AT89S52中斷INTO，定時(shí)器T0和紅外數(shù)據(jù)接收模塊組成，從而構(gòu)成紅外遙控接收器，計(jì)時(shí)器用于測(cè)量?jī)蓚€(gè)脈沖序列之間的時(shí)間間隔，計(jì)時(shí)器設(shè)置為1，時(shí)間常數(shù)為0，在每次開(kāi)始測(cè)量之前清除計(jì)時(shí)器。中斷INT0由紅外接收電路的負(fù)脈沖觸發(fā)，并且在單片機(jī)的響應(yīng)被中斷后啟動(dòng)計(jì)時(shí)器T0?？紤]到發(fā)送器和接收器的中斷響應(yīng)延遲以及信號(hào)接收器受到時(shí)間延遲的影響，接收器允許脈沖間隔，最大誤差為100us，即二進(jìn)制數(shù)字“0”間隔為400us、600us，二進(jìn)制數(shù)字“1”脈沖沖的間隔范圍為1100us、900us，不在此范圍內(nèi)的脈沖串被認(rèn)為是干擾信號(hào)或誤差。接收器在一幀中接收數(shù)據(jù)，當(dāng)紅外接
