某专用通信网络是基于卫星通信链路设计，具有带宽窄、传输时延大等特点，该网络需要对多个远端卫通站进行远程监控，而传统的网络监控协议是基于地面有线网络设计，占用带宽大，不适用于卫星信道。为满足窄带卫星信道条件下设备状态实时监控的需要，设计了基于窄带卫星信道的设备监控信息传输协议，协议中包含了设备状态发送日期、发送时间、设备标识码等基本信息，重点对参数上报数据帧结构进行了优化，根据设备参数的具体特点，将开关量参数与其他参数区别处理，有效提高了协议的带宽利用率。实际使用效果证明，采用优化的协议后，带宽利用率较优化前提高约40%，监控信息传输实时准确，方便了设备的故障排查和问题分析，提高了系统运行管理能力。

A specialized communication network is designed based on satellite communications link,and it has shortcoming of narrow bandwidth and large transmission delay. The network is required to monitor mul-tiple remote Satcom stations,but traditional ground-based network monitoring protocol is unsuitable for sat-ellite channel because it is designed based on wired network,and occupies a large bandwidth. According to the need of equipment real-time monitoring in narrow-band satellite channel situation,the transfer protocol for monitoring equipment information is designed,which includes transmission data,transmission time,e-quipment identification code etc. The data structure of parameter reported is optimized through making a distinction process between the “0”,”1” parameter and other normal parameters,thus improving the band-width utilization ratio effectively. Actual results prove that after using this protocol,bandwidth utilization ra-tio has increased by about 40% ,the transmission of monitoring information is real-time and accurate,thus providing convenience for trouble shooting and problem analysis of equipment and improving system opera-tion and management capabilities.
