【摘要】：随着科学技术日新月异的发展和计算机的广泛应用，计算机仿真培训系统越来越被逐渐向大型化、复杂化和自动化方向发展的过程工业所青睐。计算机仿真培训系统能够模拟真实工业过程中的开停车、正常运行和事故状态等现象，可实时监控被控对象的各种特性和参数变化等，不用投料，没有危险，不受外界条件的限制，具有高效率和高效益。评分系统是仿真培训系统中必不可少的组成部分，完善的评分系统不仅能够对学员的操作进行准确的评价，也能对学员应对事故的能力进行检验，并能对学员的操作进行指导。本课题针对评分系统中考核不方便和考核有失客观和公正性等问题，提出了一种立足于过程的评价方法，能够高效快速并准确的对操作人员的操作进行评价。以某锅炉供热仿真系统为研究对象，依照标准操作规程，对锅炉仿真系统设备进行多次操作并根据记录下影响操作评价的数据，并进行分析，深入研究了影响操作结果的多种因素，包括对操作步骤、操作质量和操作失误引发的报警等，根据这些评分指标建立了合理的评分规则。本文利用模糊专家系统理论，建立了评分所需模糊知识库，并以正向推理方式，实现了供热锅炉仿真培训系统中成绩自动评定系统。经过试验，作为仿真培训系统的重要组成部分，此评分系统可以监测学员的操作过程，对操作结果进行准确的评估，，并对操作失误进行指导。此成绩自动评定系统具有广泛的应用前景。
[Abstract]:With the rapid development of science and technology and the wide application of computer, the computer simulation training system is more and more favored by the process industry, which is developing towards the direction of large scale, complexity and automation. The computer simulation training system can simulate the phenomena of running and stopping, normal operation and accident state in the real industrial process, and can monitor the change of various characteristics and parameters of the controlled object in real time, without feeding and without danger. Not limited by external conditions, has high efficiency and high efficiency. The scoring system is an essential part of the simulation training system. The perfect scoring system can not only accurately evaluate the students' operation, but also test the students' ability to deal with accidents, and guide the students' operation. Aiming at the problems of inconvenient and unobjective evaluation in the scoring system, a method based on the process is proposed, which can evaluate the operation of the operator efficiently, quickly and accurately. Taking a boiler heating simulation system as the research object, according to the standard operating rules, the equipment of the boiler simulation system is operated many times and the data which affect the operation evaluation are recorded and analyzed. In this paper, the factors that affect the operation result are deeply studied, including the operation steps, the operation quality and the alarm caused by the operation error, and the reasonable scoring rules are established according to these scoring indexes. Based on the theory of fuzzy expert system, this paper establishes the fuzzy knowledge base needed for grading, and realizes the automatic achievement evaluation system in the heat supply boiler simulation training system by the way of forward reasoning. As an important part of the simulation training system, this scoring system can monitor the operation process of the trainees, evaluate the operation results accurately, and guide the operation errors. This system has wide application prospect.
