摘要
智能公交系统是城市发展的特征,是解决城市交通问题的重要途径。智能公交系统的建设可以有效提高公交行业的管理水平,提高公交系统的运行效率和服务水平,是城市公交发展的重要一步。本设计基于雄帝车载终端EMP5210C,利用设备本身具有4G、ARM、嵌入式Linux、QT等技术,实现基于整车终端EMP5210C的智能总线数据的上传和下载。本设计主要采用文件传输协议(File Transfer Protocol,文件传输协议)来完成FTP服务器与车载终端之间的可靠数据传输,避免数据丢失,尽可能多的实现车载终端与服务器之间的连接。由于机载终端EMP5210C安装的是嵌入式LINUX系统,所以在终端开发FTP功能比较麻烦。本设计采用LIBCURL跨平台网络协议库,在终端上实现FTP文件传输。
The intelligent bus system is the characteristic of the urban development and the important way to solve the urban traffic.The construction of intelligent bus system can effectively improve the management level of the bus industry,improve the operation efficiency and service level of the bus system,which is an important step in the development of urban bus industry.This design is based on the xiong di vehicle terminal EMP5210C,using the equipment itself with 4G,ARM,embedded Linux,QT and other technologies,to achieve the intelligent bus terminal EMP5210C based on the intelligent bus data upload and download.This design mainly USES the File Transfer Protocol(File Transfer Protocol)to complete the reliable transmission of data between the FTP server and the vehicle terminal,so as to avoid data loss,and the terminal has a small load on the server,so as to realize the connection between the vehicle terminal and the server as much as possible.Since the on-board terminal EMP5210C is installed with an embedded LINUX system,it is troublesome to develop the FTP function at the terminal.This design USES the LIBCURL cross-platform network protocol library to realize the FTP file transfer on the terminal.
