基于RFID的不断电道路车辆信息采集系统

RFID-based uninterruptible power road vehicles information collection system

RFID是一项非接触式自动识别技术目前已经开始应用于智能交通中,但作为无源的射频识别标签,其识别距离十分有限,因此在应用到道路车辆信息采集中具有一定的局限性,同时作为一种前端采集系统,目前采用电力线经过电源适配后给系统供电,这样在电力线路出现问题后无法保障其系统正常工作,针对这些问题,本文设计出一种改进型的基于RFID道路车辆信息采集系统,该系统通过ZigBee无线组网方式实现远距离的射频识别,通过太阳能发电模块对系统进行保障性供电可以扩大系统的应用范围。

RFID is a non-contact automatic identification technology has been applied in intelligent transportation,but as RFID passive identification distance is limited,therefore in the application of the city road traffic information collection has certain limitations,at the same time as a front end acquisition system,at present through the power line through the power supply.After the assembly to the system power supply,so the power line problems cannot guarantee the normal work of the system,aiming at these problems,this paper designs a data acquisition system based on the improved RFID road vehicles,the system of long distance radio frequency identification through the Zig Bee wireless network,the scope of application of security of supply can expand the system the system bysolar power module.
