Intelligent Evaluation Method Research And Application Of Waste Evaporation Process Training-platform

In order to further improve the effectiveness of pre-job training for employees,this article designed a practical training system for a unit's waste liquid evaporation process operation process training according to project requirements,and studied intelligent assessment methods.First,it comprehensively analyzes the training requirements of the waste liquid evaporation process,and studies the rapid development of online examination technology,simulation technology and automation technology in recent years.It proposes an intelligent evaluation method that uses the waste liquid evaporation process training platform and passes the system.Tests verify the feasibility of this method.The main contents of this article are:(1)Analyze the training content and teaching requirements of the waste liquid evaporation process,and put forward the research technical route of this article to design the practical training system with reference to the semi-physical simulation system,and at the same time use the online examination system to design the training evaluation software Subjective question scoring method;(2)Demonstrate waste liquid evaporation process flow and process failure simulation program,design physical training system through the combination of physical simulation and digital simulation,complete the training physical model,PLC control program,process simulation host computer program Design;(3)Analyze the characteristics of process operation test questions and enterprise theory test questions,design test question attribute structure table and question bank management function module,analyze the advantages and disadvantages of commonly used test paper algorithm in application,and use improved random extraction algorithm to realize automatic test paper test paper,and The effectiveness of the method was verified through experiments,and the problem of time-consuming manual paper formation was solved;(4)The problems in objective question scoring were analyzed,and the problem of diversified answers to multiple-choice questions was solved through binary coding,and the key Word matching and text semantic similarity calculation method to achieve subjective questions Automatic scoring,through experiments to verify that this method has certain effectiveness for short text scoring.Tests show that the practical training system and its intelligent evaluation method designed in this paper have effectively solved the practical problems of the process operation process proposed in the project,and further improved the pre-post practical training effect.
