Design and Implementation of Multi-Channel Data Monitoring System Based on Ethernet

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.
