基于ZigBee协议的协调器创建网络，节点自动加加入，节点通过按钮发送绑定请求，被绑定节点通过按钮应答或者接除绑定，实现ZigBee作为灯具开关，具有很高的应用价值，客服了红外的直线无遮挡传输。-Based on ZigBee protocol coordinator to create the network, the node automatically added to join, the node through the button to send bind requests, the node has been bound by the button or the next addition to answering binding, to achieve ZigBee as a light switch, with a very high value, customer service has Infrared transmission line without shelter.

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.)

T5557是兼容e555x的RFID芯片，但又具备和e555x系列芯片不同的新性能。文章着重介绍了T5557的新特点及工作原理，并对其RSK工作模式下读写器的电路设计作了分析，最后给出了D类功放和FSK解调的应用电路。-T5557 is compatible e555x the RFID chip, but with different chips and e555x series of new features. T5557 article highlights the new features and working principle and its mode RSK reader an analysis of the circuit design, and finally give the Class D amplifier and the FSK demodulator circuit applications.

基于STM32的RFID模块的RC522例程(RC522 Procedures Based on STM32 RFID Module)

chirp fourier transform 线性调频Z变换(CZT) 的matlab功能函数，该方法通过CZT变换获得精确的等价于离散傅里叶变换结果的间谐波信号的频率分布估计值,可以得到精确的各次谐波和间谐波参数,利用该函数相同采样频率下该方法的检测精度更高。(This routine allows the evaluation of the DFT over an arbitrary range of frequencies as its name implies this lets you zoom into a narrow portion of the spectrum.)

射频确认((RFID)正迅速改变生意跟踪盘货和资产的方式.从对美国国防部沃尔-马特和特斯科,早期努力正已经展示好处,但是为RFID软件,融合和数据处理使目前一挑战平息下来.如果你是一个设计师把发展一RFID系统记在一开发者金色上的,这本书是给你的.广阔经验鼓励,比尔Glover和Himanshu Bhatt为你提供重要的关于这新兴技术的信息. -Radio Frequency Identification (RFID) is rapidly changing the way businesses track inventory and assets. From Wal-Mart and Tesco to the US Department of Defense, early efforts are already showing benefits, but software, integration, and data processing for RFID still present a challenge. If you are a developer or an architect charged with developing an RFID system, this book is for you. Drawing on extensive experience, Bill Glover and Himanshu Bhatt provide you with essential information on this emerging technology.
