摘　　要：探讨了EIP应用于智能化停车场管理系统的功能,给出了在Linux环境下其软件的设计原理。程序运行在Nano-X的图形用户界面下,利用视频卡采集图像并压缩上传,采用多线程和套接字技术充分发挥Linux下网络特性,具有很强的独立工作能力和可扩展性。此外,还结合实际的编程对关键技术要点如串口通信和I/O端口操作的实现方法进行了阐述。The basic function of automatic parking management system under EIP is discussed. The design principles under Linux are described. The program is working based on the GUI of Nano-X window system. The images from the video board are compressed and uploaded. The multithreaded and socket techniques are used for taking advantage of network feature of Linux that developing network communication programs with high performance. Thus, it has strong ability of independence and expansibility. Some essential examples such as COM port communication and I/O based on operation are provided with practice.
