摘要

【目的】

随着我国长输油气管道里程的增长，油气管道阀室光通信网络在油气管道的智能化管理中发挥了重要作用。然而，时延作为光通信网络业务优化评估的重要依据，由于现有油气管道阀室光通信网络及其相对落后的技术体制等问题，光网络时延测量（DM）存在自动化程度低、DM操作周期长和对承载业务正常运行影响大等问题，迫切需要一种新型DM方案。

【方法】

文章基于光传送网（OTN）光业务单元（OSU）技术，使用OSU帧结构中的DM字段，实现了一种高精度时延计算方法。

【结果】

通过实验测试，在多种业务场景和颗粒度下，文章所设计的油气管道阀室光通信网络高精度DM机制，可在保证DM精度、无需人工现场操作和业务正常运行的前提下，实时掌握其时延状态。

【结论】

文章所提方法证明了基于OTN OSU的高精度DM机制可以为油气管道阀室光通信网络的业务时延优化和保障提供有力支持。

Abstract

【Objective】

With the growth of long distance oil and gas pipeline in our country

the optical communication network of oil and gas pipeline valve chamber plays an important role in the intelligent management of oil and gas pipeline. However

as an important basis for evaluating the optimization of optical communication network services

time delay faces challenges due to issues such as the existing optical communication network in oil and gas pipeline valve chambers and their relatively outdated technological systems. Problems with optical network Delay Measurement (DM) include low automation

long DM operation cycles

and significant impact on the normal operation of the carried services. Therefore

there is an urgent need for a new DM solution.

【Methods】

Based on the technology of Optical Transport Network (OTN) Optical Service Unit (OSU)

a high precision delay calculation method is implemented by using the DM field in OSU frame structure.

【Results】

Through experimental tests

under various business scenarios and granularity

the high-precision DM mechanism of optical communication network of oil and gas pipeline valve chamber designed in this paper can grasp its delay state in real time under the premise of ensuring DM accuracy

no manual field operation and normal business operation.

【Conclusion】

It is proved that the high-precision DM mechanism based on OTN OSU can provide strong support for the optimization and guarantee of service delay in optical communication networks within oil and gas pipeline valve chambers.
