摘要
针对集装箱码头作业过程中实时数据传输的需求,采用Java开发并实现了基于GPRS(EGPRS)网络的数据实时传输系统。阐述了系统的总体设计方案,重点对无线终端处理器资源和无线信道的特点进行了分析,在此基础上设计和优化了终端系统、终端与内网数据库的连接及通信流程。目前该系统在集装箱码头投入运用,成功地实现了无线终端与主控中心的数据实时传输。
To satisfy the requirement of real-time data transmission in the container dock,the real-time data transmission system based on GPRS(general packet radio service) or EGPRS is designed and developed by Java.The course of the total design for the system is discussed at first,and then the processor resources of the wireless terminal and characteristics of the wireless channel are analyzed mainly.Based on this,the processing of connection and communication among the terminal system,terminal unit and the database in the LAN are designed and optimized.Now,this system is applied in the container dock,and can transmit the data from the terminal to control centre.
