为提高城市非机动车辆管理中车辆查询的效率,采用嵌入式技术作为系统框架,并集成基于射频识别(RFID)技术的新一代电子车牌,设计了具有RFID信息采集、实时数据匹配和显示输出等功能的非机动车查询终端。给出了系统的硬件结构和软件设计,移植了嵌入式操作系统μC/OS-Ⅱ,最后阐述了基于多任务的功能软件的实现和查询终端的性能分析。
In order to enhance the efficiency of inquiring traffic in non motor-vehicle management, inquiries terminal for non motor-vehicles was designed by taking embedded technology as framework and integrating a new generation of electronic non motor-vehicle license based on Radio Frequency Identification (RFID) technology, which has several functions such as RFID information acquisition, data matching in real-time, output display and so on. The hardware structure and software design of this system was described, and the embedded operation system μC/OS-Ⅱ was transplanted. In the end, realization of software functions based on multi-tasks and analysis of performance were stated.
