摘要
当前门禁管理与网络请销假系统通常为有线组网模式,存在接入点不灵活且需要布线的问题,设计了一种基于ZigBee技术的无线通信门禁管理与网络请销假系统,并给出了系统整体框架和硬件、软件方案,重点对硬件中的进出门人脸识别模块进行了设计。通过分析PCA算法在人脸识别中的应用,提出透视变换改进的PCA算法,丰富了系统人脸识别模块的样本。最后通过仿真实验和系统测试,验证了本研究算法的有效性和系统的可行性。结果表明,本研究基于改进PCA算法的人脸识别率较高,达到92%,相较于标准PCA算法,识别率提高了11%,且不影响识别的耗时;整个系统可正常稳定运行,满足设计需求,可用于实际门禁管理和网络请销假。
In view of the current access control management and network leave system is usually wired network mode,there are access points are not flexible and need unlimited problems,this paper designs a wireless communication access control management and network leave system based on ZigBee technology,and gives the overall framework of the system and hardware,software solutions,focusing on the design of the hardware in and out face recognition module.By analyzing the application of PCA algorithm in face recognition,an improved PCA algorithm based on perspective transformation is proposed,which enriches the sample of face recognition module.Finally,the effectiveness of the algorithm and the feasibility of the system are verified by simulation and system test.The results show that the face recognition rate based on the improved PCA algorithm is higher,reaching 92%.Compared with the standard PCA algorithm,the recognition rate is increased by 11%,and the time-consuming of recognition is not affected;The whole system can run normally and stably,meet the design requirements,and can be used for actual access control management and network leave.
