基于无线局域网标准的天然气长输管道通信系统的整合

通信系统在天然气长输管道的生产运营中起着至关重要的作用。目前陕西省天然气股份有限公司通信网由公司总部、西安、延安、杨凌分公司及22个输气场站等多个不同的独立建设的系统构成，各自独立建网形成了一个个“信息孤岛”。采用基于无线局域网标准的VOIP系统整合陕西省天然气股份有限公司通信网，一方面可使闲置的带宽得到充分利用．另一方面也能有效降低系统内部通信费用，有效消除通信障碍，提高工作效率和企业管理水平。

Integration of Communication Systems on Natural Gas Long Distance Pipelines Based on the Standards of Wireless Local Area Network

The communication system takes the key role in the production and operation of natural gas long distance pipelines. At present, the communication network in Shaanxi Natural Gas Company is made up of multiple different independent construction systems such as the headquarter of company, branches of Xi＇an, Yanan, Yangling and so on. Independent construction of their networks results in a lot of information isolated island. Therefore, VOIP system based on the standards of wireless local area network is applied to the integration of communication networks in Shaanxi Natural Gas Company. This method, on the one hand, can make the best use of empty bands, and on the other hand, can effectively lower the expenses of communication in the system, and remove the ban＇ier of communication successfully, thus improving the work efficiency and management level of enterprises.
