摘要：這些年以來，計(jì)算機(jī)技術(shù)的高度發(fā)展使得其在社會各領(lǐng)域越發(fā)的不可替代, 而隨之單片機(jī)技術(shù)的發(fā)展也使其相關(guān)應(yīng)用正在不斷地走向深入，同時(shí)帶動了傳統(tǒng)控制檢測日新月益的更新。 IC 卡考勤機(jī)是在實(shí)際工作生產(chǎn)中提出的研究課題，在實(shí)際工作中對每個員工的出勤情況的統(tǒng)計(jì)是企業(yè)事業(yè)單位人力資源管理的一項(xiàng)重要內(nèi)容。智能 IC 卡考勤機(jī)能夠智能的記錄員工的出勤、缺席、遲到、早退次數(shù)，以此來更好的約束員工養(yǎng)成良好的出勤習(xí)慣。每個員工在一定時(shí)間內(nèi)的出勤情況一目了然，方便了領(lǐng)導(dǎo)對員工出勤情況的統(tǒng)計(jì)。 本設(shè)計(jì)主要采用高性能、低功耗的STC89C52 單片機(jī)為控制核心,鍵盤輸入、顯示和存儲采用串口連接的方式，鍵盤輸入為4×4 鍵盤，鍵盤除了0~9 十個數(shù)字鍵外還設(shè)有方便查詢工作的功能鍵，12864液晶顯示屏在平時(shí)可顯示年、月、日或時(shí)間，每個員工在上班和下班的時(shí)候打卡，系統(tǒng)自動記錄打卡時(shí)間，然后和系統(tǒng)設(shè)定好的時(shí)間進(jìn)行對比，從而判定員工的出勤，缺席，遲到，早退情況，智能 IC 卡考勤機(jī)會將員工每天的出勤情況進(jìn)行累加，方便查詢者更快的了解員工一個階段的出勤狀況。 本設(shè)計(jì)力爭做到準(zhǔn)確、實(shí)用、節(jié)省時(shí)間、操作方便。 關(guān)鍵詞：單片機(jī)；IC卡系統(tǒng)；考勤機(jī)；畢業(yè)設(shè)計(jì)
ABSTRACT：Over the years, the height of the development of computer technology makes it more in all the fields of society is irreplaceable, and then the development of the single chip microcomputer as the relevant applications are constantly to the deepening, and push the traditional control test on the renewal of the new benefit. IC attendance machine is in the actual work presented in the production of the research subject, the actual work of each employee attendance statistics is enterprise institution of human resources management is an important content. Smart IC attendance record of the employees to intelligence attendance, absent, late, leaving early times, in order to better constraint employees develop good attendance habit. Each employee in a certain time attendance at a glance, convenient a leadership to the employee's attendance of statistics. This design mainly adopts the high performance, low power consumption STC89C52 microcontroller as control core, keyboard input, display and storage of the serial port connection way, the keyboard input for 4 x4 keyboard, the keyboard in addition to 0 ~ 90 digital key outside also has a convenient inquires the work function keys, 12864 LCD screen can be shown in ordinary day, month and year or time, each staff at work and in the evening punch, the system can automatically record clock time, and then set good time for comparison system by which to judge the employee attendance, absent, to be late, intelligent IC attendance opportunity will employees daily attendance cohorts, convenient inquirers faster understanding staff a stage of the attendance status. This design strive to be accurate, practical, save time, easy to operate. Key words: SCM; IC Card; Attendance; Graduation Design
