畢業(yè)設(shè)計論文—賓館用保險箱電子密碼設(shè)計



論文成品，適合電子信息科學(xué)與技術(shù)，計算機(jī)等專業(yè)的畢業(yè)論文選題。



摘要

　　　電子密碼鎖是通過輸入密碼，控制電路工作，由電路控制機(jī)械結(jié)構(gòu)開鎖或關(guān)鎖的電子產(chǎn)品。它具有保密性好、使用靈活、操作簡單、壽命長的特點。為方便客人隨時存取小件貴重物品或現(xiàn)金，有條件的賓館會在客房提供一個基于電子密碼鎖的保險箱。本設(shè)計完成的電子密碼鎖系統(tǒng)采用單片機(jī)AT89S52為核心元件，基于MCU強(qiáng)大的可編程功能,系統(tǒng)主要由輸入模塊、顯示模塊、提示模塊、開關(guān)模塊、控制模塊、報警模塊六部分組成。其中輸入模塊由4*4鍵盤和液晶顯示屏構(gòu)成，密碼6位數(shù)可由用戶任意設(shè)定,且設(shè)有萬能密碼,在客人忘記使用密碼時,亦可開鎖。當(dāng)輸入錯誤密碼次數(shù)超過設(shè)定次數(shù)時, 能自動鎖住保險箱并發(fā)出報警。電子密碼鎖的保險箱操作簡單，客人只需根據(jù)提示按照順序操作即可讓讓保險柜處于密碼保護(hù)之中。

ABSTRACT

　　　Electronic combination lock is through the input password, control circuit, control of mechanical structural lock or shut by circuit electronic products. It has good secrecy, the use of flexible, simple operation, long service life. For the convenience of the guests at any time access to small valuables or cash, conditional hotel will be in the guest room to provide a safe based on electronic combination lock. This design completed electronic combination lock system USES single-chip AT89S52 as the core components, based on the MCU powerful programmable functions, system mainly by the input module, display module, module, alarm module, switch module, control module of six parts. Which input module consists of 4 * 4 keyboard and LCD screen, 6 digits password can be set freely by the user, and is equipped with universal password, when the guest forget to use the password, can open the lock. When input the wrong password more than setting number, can automatically lock the safes and issue a report to the police. Electronic combination lock safe operation is simple, the guest need to order, according to the prompt operation can make safe under password protection.


Keywords: Single-chip microcomputer AT89S52，Electronic combination lock，safe box
