摘　　要：在卫星导航系统的远程监控应用中,可靠的数据传输是重要的环节。在卫星导航系统工程中,数据传输有数据量大、多路数据并发和要求传输实时性高等特点。针对工程小型化的需求,自主研发了可实时进行多路设备的串口数据转发,并方便远程监控计算机监控设备的单板卡设计。它利用集成器件XPORT进行串口转网络协议,实现了设备与监控计算机网络的直接通信。该设计提高了设备的集成度,具有成本低、可靠性和可扩展性高的特点,方便工程使用。在实际的应用中验证了设计的稳定性。Data transmission is a crucial part in remote monitoring RDSS system.The data transmission in satellite navigation sys-tem engineering is characterized by large amount of data,multichannel data concurrency and transmission in real-time.To downsize the project equipment,a single board is developed independently that can forward multiplexed serial data in real-time and make it conven-ient to monitor from remote monitoring computer.The integrated device XPORT is used to transfer serial interface into network protocol. Therefore,the equipment can communicate directly with remote monitoring computer through the network.This design features high inte-gration,low cost,high reliability and scalability,and is easy to use in project.The stability of this design isverified in practical applica-tions.
