【摘要】 随着现代信息技术和网络技术的迅猛发展,资源和市场分布也在向全球性发展,促使企业必须建立基于Internet的远程诊断系统。鉴于远程故障诊断技术的独特优势,把远程故障诊断的一般原理应用于输油管线,建立了输油管线远程故障诊断系统,该远程故障诊断系统由本地监测诊断系统、数据通信网络和远程诊断中心3部分组成。在本地监测诊断系统中尝试应用了智能客户端技术,提高了现场与诊断中心通信的智能性。在远程诊断中心中探讨了Web数据库技术和专家系统在输油管线远程故障诊断系统中的应用,建立了适合输油管线情况的诊断数据库和专家系统模型。该输油管线远程故障诊断系统经试运行,取得了良好的经济效益。更多还原

【Abstract】 By applying the general criteria of remote fault diagnosis on the oil pipeline, a remote fault diagnosis system of the oil pipeline is developed. This fault diagnosis system is comprised of local monitoring and diagnosis system, data communication network and remote diagnosis center. The intelligent client-side technique is adopted in the monitoring and diagnosis system to improve the intelligence of the communication between the job site and diagnosis center. The Web database technique and expert system are set up and used in the remote diagnosis center of the oil pipeline. Pilot running of the remote fault diagnosis system of oil pipeline brings about remarkable financial profits.更多还原
