介绍了专家系统的特点和应用,分析了大型真空冶金抽气装置的特性、故障多发原因以及排查中的困难,指出采用专家系统的可行性和实际意义,明确了在真空冶金抽气装置中建立专家系统的具体内容。以宝钢RH-KTB炉外精炼真空系统为例,给出了设备运行监测方案,建立了专家系统知识库,编制的软件可对设备的运行状态进行即时评价和故障预报,当真空系统出现故障时,采用逆向推理机制,从目标出发,寻找故障可能原因,并给出推理解释。专家系统对监测参数阈值的机器学习,提高了专家系统实际应用中的推理效率和准确性。专家系统软件经离线测试和现场在线应用达到预期的目标,可以推广应用。
The characteristics and applications of the expert system are introduced. The characteristics of large vacuum metallurgical aspirating device, the cause of the troubles and the difficulties in the troubleshooting are analyzed. The feasibility and practical significance of the expert system are pointed out. The establishment of the vacuum metallurgical aspirating device The specific content of the expert system. Taking Baosteel RH-KTB external refining vacuum system as an example, the equipment operation monitoring program was given and an expert system knowledge base was established. The software was compiled to evaluate the equipment operating status immediately and forecast the failure. When the vacuum system failed , The use of reverse reasoning mechanism, starting from the goal, to find the possible causes of failure, and to explain the reasoning. The expert system monitors the threshold of parameter machine learning, which improves the efficiency and accuracy of reasoning in the practical application of expert system. Expert system software offline test and on-site application to achieve the desired goal, you can promote the application.
