摘要：隨著科學技術(shù)的不斷發(fā)展，人們對日常生活中的安全保險器件的要求越來越高。為滿足人們對鎖的使用要求，增加其安全性，用密碼代替鑰匙的密碼鎖應運而生。密碼鎖具有安全性高、成本低、功耗低、易操作等優(yōu)點。 本文從經(jīng)濟實用的角度出發(fā)，采用美國Atmel公司的單片機AT89S52與低功耗CMOS型E2PROM AT24C02作為主控芯片與數(shù)據(jù)存儲器單元，結(jié)合外圍的遙控輸入、顯示、報警、開鎖等電路，用c語言編寫主控芯片的控制程序，設(shè)計了一款可以多次更改密碼具有報警功能的遙控電子密碼鎖。 主要的設(shè)計實施過程：首先，選用 ATMEL公司的單片機 AT89C52，以及選購其他電子元器件。第二步，使用 Client99SE設(shè)計硬件電路原理圖，并設(shè)計 PCB圖完成人工布線（后因 PCB 板損壞決定采用萬能板焊接的方法）。第三步，使用 Keil uVision3 軟件編寫單片機的 C 語言程序、仿真、軟件調(diào)試。第四部，使用 PROTEUS 軟件進行模擬軟、硬件調(diào)試。最后，聯(lián)合軟、硬件調(diào)試電路板，完成本次畢業(yè)設(shè)計。 關(guān)鍵詞：AT89C52；密碼鎖；遙控
ABSTRACT：Along with science and technology unceasing development, The needs of people is more and more high to daily life safe insurance component request. In order to satisfy the people blockage the operation requirements, increases its security, replaces the key with the password the password lock to arise at the historic moment. The password locking device prevent going in has the security high, the cost low, the power loss low, easy to operate and so on the merits. For practicality, this paper designs a new electronic cipher lock, which has the function of alarm and whose cipher can be changed many times. This cipher lock uses AT89S52 SCM and E2PROM AT24C02 as main chip and data memory cell . The author made this ciphor lock by use of making controlled program of master CMOS with periphery electro circuit of keyboard input, display, alarm and unlock. Main design implementation process: First, selects ATMEL Corporation monolithic integrated circuit AT89C52, as well as selects and purchases other electronic primary device. Second step, uses the Client99SE design hardware electric circuit schematic diagram, after (because and designs the PCB chart to complete the artificial wiring PCB board damage decision to use multi-purpose board welding method).Third step, uses Keil the uVision3 software to compile the monolithic integrated circuit the C language procedure, the simulation, the software debugging. Fourth, uses the PROTEUS software to carry on the simulation software and hardware debugging. Finally, union software and hardware debugging electric circuit board, cost graduation project. Key words: AT89C52；Password lock；Remote control
