基于RFID技术的停车场通讯系统的设计

提出红外通讯与无线通讯结合在停车场通讯系统中,为了克服目前停车场通讯系统中,相邻车道之问无线通讯的相互干扰,该通讯系统引进具有方向性特点的红外通讯;设计了功率可控红外发射电路,从而达到停车场通讯系统中车道口的通讯距离可调,采用射频识别技术中的导出密钥的相互鉴别实现数据安全;通过局域网完成各车道口之间以及各车道口与管理中心的信息交换,实现停车场管理的网络化和信息化;实际证明,该通讯系统具有实际的应用价值。

A Design of Park Communication System Based on RFID Technology

In order to avoid wireless communication interference between close driveways in park communication system at present, the infrared communication having directional characteristic is introduced into the park communication system; At the same time infrared communication power can be controlled in designed circuit, and communication distance can be regulated at the gate of driveway in the park communication system, all of which are attributed to combining infrared communication with wireless communication in the communication system. The data security is achieved by the identification of educed key. The information exchange can be completed through Ethernet between these driveways and the management center, which can realize network and information management of the park. The communication system was proved to be application value in the practical experiment.
