Description: This project aimed to develop a wireless system to detect and allow only the authorized persons. The system was based on Radio Frequency Identification (RFID) technology and consists of a passive RFID tag. The passive micro transponder tag collects power from the 125 KHz magnetic field generated by the base station, gathers information about the Tag ID and sends this information to the base station. The base station receives, decodes and checks the information available in its Database and Manchester code was used to send those information. The system performed as desired with a 10cm diameter antenna attached to the transponder. The Base Station is built by using the Popular 8051 family Microcontroller. It gets the tag ID and if the tag ID is stored in its memory then the microcontroller will allow the person inside.

Description: 近些年，由于射频技术发展迅猛，应答器有了新的说法和含义，又被叫做智能标签或标签。RFID电子电梯合格证的阅读器（读写器）通过天线与RFID电子标签进行无线通信，可以实现对标签识别码和内存数据的读出或写入操作。典型的阅读器包含有高频模块（发送器和接收器）、控制单元以及阅读器天线。RFID射频识别是一种非接触式的自动识别技术，它通过射频信号自动识别目标对象并获取相关数据，识别工作无需人工干预，可工作于各种恶劣环境。RFID技术可识别高速运动物体并可同时识别多个标签，操作快捷方便。RFID是一种简单的无线系统，只有两个基本器件，该系统用于控制、检测和跟踪物体。系统由一个询问器（或阅读器）和很多应答器（或标签）组成。-In recent years, the rapid development of the radio frequency technology, the transponder has a new argument and meaning, also called smart tags or labels. The RFID reader elevator certificate (reader) through the antenna and the RFID tag for wireless communications, can be achieved for tag identification code and the memory data read or write operations. A typical reader includes a frequency module (transmitter and receiver), the control unit and the reader antenna. RFID radio frequency identification is a non-contact automatic identification technology that uses radio frequency signal automatic target recognition and access to relevant data, identifying work without human intervention, can work in a variety of harsh environments. RFID technology can identify fast moving objects can also identify multiple tags, the operation quickly and conveniently. RFID is a simple wireless system, only two basic components, the system for control, object detection and tracking. System consists of a Platform: |
