基于二代证的嵌入式门禁系统的设计

 随着中国换发第二代居民身份证（简称二代证）计划的推广，目前二代证已得到普及。作为射频卡的一种，二代证继承了射频卡的优点，并采用了数字防伪技术和印刷防伪技术，其安全性得到了较大程度的提高。鉴于其安全性、普及性且唯一性，二代证可以应用在安防系统中作为个人身份识别的唯一标识。在分析门禁系统发展现状的基础上，设计了一款符合当前门禁系统发展趋势、集现代化和智能化于一体的二代证门禁控制系统。目前，已完成该软件的需求分析、设计、实现及测试工作。针对该系统的功能及性能测试表明，该系统满足设计要求，且具有安全性高、实时性强、识别效率高等特点。

Design of an embedded second-generation personal ID card access control system

The second-generation Chinese personal ID card has been widely used with the national tries to popularize it. The secondgeneration Chinese personal ID card inherits the advantages of the contactless IC card. With the adoption of digital anti-forgery technology and printing anti-counterfeit technology, the security of this second-generation ID card has been greatly enhanced, with the characteristics of security,, popularity and uniqueness for the unique identification in the security & protection system. This article analyzes the current situation of the access control system, and designs an embedded second-generation personal ID card access control system. At the moment, requirements analysis, design, implementation and testing work have been completed. The test results show that the second-generation personal ID card access control system meets the design requirements completely. This access control system is highly secure, real time and efficient. It can be put into production and popularized.
