RFID网络*自适应记忆标签防冲突协议

MFRC522测试程序(MFRC522 test program)

电子标签防碰撞是RFID 系统中一个关键问题。在射频识别系统中．当阅读器作用范围内有多个标签同时向阅读器发送数据时，会产生冲突，必须采用一种防碰撞算法解决这种冲突。在分析典型的二进制及动态二进制防碰撞算法基础上，采用了一种新的防碰撞算法。经实验证明，该算法能有效解决射频识别系统中多目标识别的防碰撞问题。(Tag anti-collision RFID system is a key issue. In the radio frequency identification systems. When the reader within the framework of the role of multiple tags simultaneously send data to the reader, it will create conflict, you must use a anti-collision algorithm to solve such conflicts. In the analysis of a typical binary and dynamic anti-collision algorithm based on the binary, using a new anti-collision algorithm. The experiments show that the algorithm can effectively solve the radio frequency identification system, multi-target recognition of the anti-collision problem.)

说明：  为了系统的安全性，为门禁控制系统增加了登录功能，通过从后端数据库录入管理员信息，包括用户名与密码，便可在用户界面使用数据库中的信息进行登录，极大的保证了系统的安全性。用户可以通过数据库匹配方法来对ID卡进行登记、删除等操作。(In order to ensure the security of the system, the login function is added to the access control system. By inputting administrator information from the back-end database, including user name and password, the information in the database can be logged on in the user interface, which greatly guarantees the security of the system. Users can register and delete ID cards through database matching method.)
