对无线局域网的基要概念、传输介质、技术标准及拓扑结构进行了介绍。针对输送管道的地理位置特点,提出了建立基于无线局域网的输送管道实时检测系统的解决方案,实现了检测点和厂区局域网的互联,并对方案中的数据采集、数据传输、泄漏检测和定位进行了详细讨论。对于输送管道泄漏,综合运用包括小波分析在内的多种信号处理方法,能够及时、准确地检测并定位泄漏点。 The basic concepts of wireless LAN, transmission media, technical standards and topology are introduced. According to the characteristics of the geographical location of the pipeline, a solution to establish a real-time detection system of the pipeline based on wireless LAN was put forward. The interconnection between the detection point and the plant LAN was realized and the data acquisition, data transmission, leak detection and location in the scheme were carried out A detailed discussion. For the pipeline leakage, the comprehensive use of a variety of signal processing methods, including wavelet analysis, can detect and locate leaks timely and accurately.
