此代码为RFID中防冲突算法中固定帧ALOHA算法的的碰撞率，正确率和空闲率的模拟和仿真(this code for RFID defense conflict algorithm fixed frame ALOHA algorithm collision rate correct rate and the rate of idle modeling and simulation)

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.)
