基于RFID技术的智能小区巡更系统开发与实现

本文针对智能小区安防系统的实际，提出一种基于RFID和GPRS技术的巡更系统。系统由巡更节点、巡更终端机及监控管理上位机构成。巡更节点采用非接触式智能卡，实现电子标签功能；巡更终端机具有节点信息读取、信息处理、无线通信功能；设计采用AT89S52作为控制器，扩展相应的外围电路，并通过GPRS无线接口与监控管理上位机进行通信。监控管理上位机具有无线接口，接收终端机发来的信息，实现远程信息监控。系统采用了最新的物联网技术，经实际运行巡更系统工作稳定，满足了智能小区安防的需要。

Development and Implementation of Intelligent Community Patrol System Based on RFID

Aiming at the problems of security system of intelligent community, the patrol system is proposed based on the RFID and GPRS technology. The system is composed of the patrol node, patrol terminals and management software of host computer. The contactless smart card is used as the patrol nodes, which finish the electronic tags. The patrol terminal is used to read node information, process information, communicate with the wireless connection. AT89S52 is designed as the controller, and peripheral circuit is extended. GPRS wireless interface is used to connect the patrol terminals and the host computer. The patrol information is transferred to the host computer for the remote monitoring. The latest Internet of Things technology is applied. It is proved that the system is stable and reliable by the actual operation of patrol system, to meet the needs of intelligent community security.
