摘要
针对现有的电子考勤系统在实时性和准确性方面的不足,设计并实现了一款基于局域网的电子考勤系统。系统以STC12单片机为控制核心,配以高性能的非接触式IC卡读写芯片MF RC522和系统时钟芯片,借助Wi Fi232-B无线通信模块和液晶模块,完成了考勤人员的实时数据录入和无线传输,同时给出了系统各模块的具体软硬件设计。中天科技车间员工的现场测试表明,该考勤系统具有准确性高、实时性强和数据传输可靠等优点,具有很好的市场应用前景。
Aimed at the deficiencies of real-time performance and accuracy in existing electronic attendance systems,an electronic attendance system based on LAN is designed and implemented. In the system,STC12 single chip computer is selected as the control core,the high-performance and non-contact IC R / W chip MF RC522 and system clock chip are accompanied,and with help of Wi Fi232-B wireless communication module and LCD module,real-time data entry and wireless transmission of the attendance staff are completed. The specific design of hardware and software of each module in the system is given. The on-site test by ZTT workshop staff shows that the system has the advantages of high accuracy,strong real-time performance and reliable data transmission,as well as has good market and application prospects.
