面向输电线路监测的无线自组织网络多业务支持方案研究 Studies on Wireless Ad Hoc Networks Scheme to Support Multi-Services Oriented to Power Transmission Line Monitoring

输电线路监测包含多种业务，由于不同业务对时延、带宽、时延抖动等服务质量有不同的要求，因此，需要一个能够支持多业务接入、并提供相应服务质量保证机制的网络来满足监测的需求。无线自组织网络具有组网方便灵活、可扩展性强、维护简单等优点，近些年来已在电力行业得到了广泛的应用。本文提出了一种基于无线自组织网络的输电线路监测多业务接入方案，能够在无线自组织技术的支持下，满足多种业务在同一个网络中传输的需求，同时针对不同级别的业务，尤其是实时性要求很高的业务，提出识别和分类模型，进行不同的QoS管理，保障相应业务的QoS. The power transmission condition-base monitoring system includes a variety of services. As the different services have different requirements on QoS, such as delay, bandwidth and delay jitter, we need introduce a kind of effective multi-service access strategy and an appropriate quality of service. Mobile Ad Hoc Networks have advantages of convenient organization, flexible scalability, and easy maintenance. In recent years, it has been widely used in the power industry. This article proposed a power transmission line monitoring multi-service access strategy based on the Mobile Ad Hoc Network, which can meets the requirements of multi-services transmitting in the same network. To high real-time, especially, author proposes an identification and classified model, managing different sevices to assure the corresponding QoS.
