摘要
根据无人机地面仿真实验的需要,针对传统串口一对一连接模式单一、传输速率较慢的现实状况,选用具有以太网功能接口的串口服务器代替多串口卡,可方便地将各路串口数据流引入以太网,实现多台上位机分布式的监控与处理;介绍了基于串口服务器的组网结构和多通道数据监控系统的设计方法,详细叙述了UDP传输协议的选择和网络程序的设计与实现;结果表明,采用此方案可以使系统既具有串口通信简单方便的特点,又实现了以太网通讯的高效和稳定。
According to the realistic condition that traditional serial port＇s unitary connection mode and low transmission rate,the serial device server which exhibited ethernet function interface is adopted to replace the multi-serial port card for the the requirement of ground simulation experiment for UAV.Serial data streams are transmited to the ethernet conveniently and thereby distributed monitoring with multi-host can be realized.The networking structure and the design of multi-channel data monitoring based on serial device server are introduced.Moreover,the choosing reason of UDP protocol and the development of networking program are described in detail.The result indicates that the system not only has the feature that simple communiation of serial port but also implement high performance and steady operation of ethernet.
