IC卡電子門鎖控制系統(tǒng)硬件設(shè)計(jì)與實(shí)現(xiàn)

全文36頁(yè) 約14000字 論述翔實(shí)

摘要：隨著科技的進(jìn)步，以單片機(jī)為核心的自動(dòng)門鎖控制系統(tǒng)已經(jīng)開始進(jìn)入了人們的生活。本論文著重闡述了以MCS-51系列單片機(jī)為核心，通過(guò)可編程并行接口8255直接控制LCD液晶顯示器模塊及鍵盤掃描，并與接觸式IC卡讀寫技術(shù)相結(jié)合的系統(tǒng)。為保證門鎖使用的安全性，系統(tǒng)自動(dòng)比較IC卡密碼和用戶輸入密碼，若輸入的密碼與系統(tǒng)讀出的IC卡密碼相同，門鎖自動(dòng)開啟；若連續(xù)輸入三次錯(cuò)誤的密碼，系統(tǒng)自動(dòng)停止此卡的使用，并及時(shí)將報(bào)警信號(hào)通過(guò)RS-485串行通信總線傳往主控臺(tái)。本設(shè)計(jì)的優(yōu)點(diǎn)是硬件電路簡(jiǎn)單，軟件功能完善，控制系統(tǒng)可靠，具有一定的實(shí)用價(jià)值。該系統(tǒng)拓展后，可用于其他智能家電的控制，具有好的應(yīng)用前景。

The hardware design and realization of IC card electronic door locks controlling system

Abstract：With the progress of technology, the automatic door locks control system which takes the the Single Micro Chip Computer as the core is stepping into people's lives. This paper focuses on the system which takes the series Single Micro Chip Computer MCS-51 as the core, which controls Liquid Crystal Display modules and keyboard scanning through the 8255 chip directly, and contacts the IC card read-write technology. In order to guarantee the security of the door lock's use, the system design offers an comparision between the IC card password and the password which the user input. If inputed password and the IC card password read out on the system read-out are same, the door lock will be opened automaticly. If you input wrong password three times continuously, the system will automatically stop the use of the card, and the alarm will be transmited to the key station promptly through the RS-485 serial telecommunications bus st-bus. The advantage of this design is simple in the hardware circuits, software functional improvements, the control system′s reliablily, and has certain practical. After this system is developed, it can be used in other intelligent electrical appliances' control and has a good application prospect.
