基于ARM的泊车手持机应用技术研究
摘要
针对城市交通中的停车难问题,课题组研制了有效的泊车管理系统,泊车手持机是泊车管理系统的重要组成部分之一,完成车辆的信息输入任务及对车辆实现有效监管。泊车手持机主要实现与泊车咪表的无线通信,读写会员车主IC卡,车牌图像的采集和提供友好的交互操作界面,并实时处理车辆的进出信息,完成泊车费用的结算。
提出了泊车手持机的硬件设计方案,详细描述了系统软件模块的设计及实现过程。系统硬件平台采用了基于ARM体系架构的S3C2440作为核心处理器,外围扩展了nRF24E1无线收发芯片、ZLG500AGT读卡模块、CMOS7620摄像头。在此硬件平台的基础上,探讨并解决了嵌入式linux系统软件平台的搭建,包括以下方面:交叉编译工具链的建立、QT的移植、Linux内核移植、文件系统制作、嵌入式数据库SQLite3的移植和GDB远程调试环境的建立。完成了处理器与无线芯片的串口程序设计,读卡设备的驱动编写,摄像模块的驱动编写以及用户界面软件的设计,实现了泊车手持机的功能。通过调试表明,系统达到了设计要求,设计方案可行并具有良好的应用前景。
An effective parking management system has been developed to solve the parking problems of urban traffic. Parking handset is an important part of the parking management system, by which the vehicles information was inputted and the vehicles was supervised and managed effectively. The Parking handset implement many functions such as the wireless communications with Parking Meters, reading and writing the IC of member owners, acquisition images of the vehicle number, providing a friendly interactive interface, furthermore, processing the vehicle access information real-time and charging the parking fees.
The hardware design solution was advanced, and the design and realization of software modules of parking handset is described in detail. System hardware platforms used S3C2440 processor based on ARM architecture as core microprocessor and external expand the nRF24El radio transceiver chip, ZLG500AGT module, CMOS7620 camera. On the basis of this hardware platform, software platform based on the embedded Linux system was built, including: the establishment of cross compiler tool chain, QT transplant, Linux kernel transplantation, the facture of file system, embedded database SQLite3 transplant, and the build of remote debugging environment of GDB server. Serial programming based on wireless chip, the driving of reader equipment, the realization of camera module and user interface software designs were accomplished. Thus the functions of the parking handset were achieved. The debugging shows design is up to system requirements, and the design of parking handset is viable. The handset has a good application prospect.
