摘要
随着信息技术的飞速发展,传统的课堂签到模式已不再适用。二维条码不仅具有快速识读、数据容量大、纠错能力强和可靠性高等优点,还可进行中文编码,更适合表示汉字,已逐渐被使用作为新的课堂签到方式。本文基于分布型数据库的思想设计了二维码的手机签到系统,该系统通过任务控制和系统控制的方式支持整个系统的有效运行,为设计出高效、低碳环保的课堂签到系统提供了有力的保障。
With the rapid development of information technology,the traditional classroom sign-in model is no longer applicable.QR Code not only has the advantages of rapid reading,large data capacity,strong error correction ability and high reliability,but also can be used for Chinese coding,more suitable for the representation of Chinese characters,which has been gradually used as a new way of classroom sign-in.Based on the idea of distributed database,this paper designs a mobile QR Code sign-in system,which supports the effective operation of the whole system through task control and system control,and provides a powerful guarantee for the design of an efficient,low-carbon and environment-friendly classroom sign-in system.
