| 摘要: |
| 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。 |

| Abstract: |
| 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 multiple remote Satcom stations,but traditional ground-based network monitoring protocol is unsuitable for satellite 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,equipment 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 bandwidth utilization ratio effectively.Actual results prove that after using this protocol,bandwidth utilization ratio 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 operation and management capabilities. |
