目前小区的车辆管理,尤其是进出小区道闸的开关及进出车辆的记录,主要还是依靠短距离非接触式IC卡和人力来完成的,不仅使用不便,而且出错率高,对小区内部车辆的安全管理造成不便。结合今年来逐渐成熟的RFID射频识别技术,针对小区车辆进出管理的实际需求,设计了本系统。解决由于IC卡读卡距离短,效率低等问题。介绍一种基于AVR单片机和有源RFID道闸管理系统,该系统主要由AVR单片机、射频发射及读写模块、PC基站、红外监测模块、监视模块、道闸控制模块等组成,具有体积小、功耗低、成本低、高性能的特点。
At present, the management of vehicles in the community, especially the switch-in and out-going vehicles in and out of the cell gate, is mainly based on the short-distance contactless IC card and manpower, which not only causes inconvenience to use but also has high error rate. Inconvenience caused by safety management Combined with the gradual maturity of RFID radio frequency identification technology this year, this system has been designed according to the actual needs of community vehicles entering and leaving management. IC card reader to solve the problem of short distance, low efficiency and so on. This paper introduces an AVR microcontroller and active RFID gateway management system. The system mainly consists of AVR microcontroller, RF transmitter and writer module, PC base station, infrared monitoring module, monitoring module and barrier control module. It has the advantages of small size, Low power consumption, low cost, high performance.
