基于Wi-Fi指纹的移动考勤系统设计与实现

摘要

本文介绍了传统的Wi-Fi指纹定位技术及其优缺点，并针对其缺点做出了改进，将其应用至移动考勤场景中，提出了一种基于Wi-Fi指纹技术的移动考勤方案，并基于此方案设计实现了一个基于Wi-Fi指纹技术的移动考勤系统。使用基于该方案开发的考勤系统，可以允许员工在任何有 Wi-Fi 覆盖的区域使用手机进行考勤，不受考勤机放置限制，同时节省了考勤机的设备成本；Wi-Fi指纹自动更新机制也节省了指纹定期维护的人工成本。%This paper introduces traditional Wi-Fi fingerprint location technique and its advantages and disadvantages, does necessary improvement based on that. It also presents a mobile attendance solution based on Wi-Fi fingerprint location technique and implements it in this paper. Mobile attendance system based on improved Wi-Fi fingerprint location tech-nique allows stuff to turn up at any place where there are Wi-Fi access points, it can save the cost of attendance machines and manual work of maintaining fingerprints via Wi-Fi fingerprints automatic updating mechanism.
