摘　　要：介绍了无线局域网的基本概念、传输介质、技术标准及拓扑结构。针对输送管道的地理位置特点,提出了基于无线局域网的输送管道实时检测系统方案,用来实现检测点和厂区局域网间的互联。并详细讨论了方案中的数据采集、数据传输、泄漏检测和定位。输送管道泄漏,综合运用多种信号处理方法,如小波分析等,从而能够及时、准确地检测并定位泄漏点。该系统已应用于输油管道,并取得了良好的效果。The basic concepts, transmission media, technical standards and topological structures ot the wireless local area network are introduced. In accordance with the geographic characteristics of the pipeline located, the strategy of real time pipeline leakage detection system based on wireless local area network is presented. By using it, the inter-connection between detection site and local area network of the plant is realized. The data acquisition, data transmission, leakage locating and detection in the strategy are discussed in detail. With the relevant signal processing methods, e.g. wavelet analysis, the leakage location can be accurately detected and positioned in time. The system has been operated in petroleum pipeline with excellent effects.
