| Process Industrial production process achieving automatic control of the whole process plays an important role in improving production efficiency and product quality,reducing energy consumption and material consumption and ensuring production safety.The goal of industrial automation is to train senior engineers and technicians who are engaged in the analysis,design,implement,operation,maintenance and development of control systems in the field of automation.It not only need students to master the basic theoretical knowledge of automatic control,but also need to strengthen students’Conceptual understanding and skill mastery of technical applications.With the support of Liaoning Province Metallurgical Comprehensive Automation Engineering Laboratory Construction Project and taking the case of the implementation of the automation engineering of the whole process of mineral processing as the background,a simulation platform of the whole process virtual instrument and actuator of dressing process oriented to case teaching was set up.The platform can simulate the experiment to show students the key knowledge points such as classification of instrument and actuator in the whole process of mineral processing automation,selection,configuration,I/O channel assignment,operation and dynamic characteristics in the automation of mineral processing,which has become effective Experimental tools in enhancing the level of industrial automation teaching.The main work of this thesis is as follows:1.This thesis analyzes the characteristics of virtual instruments and actuators in the whole process of mineral processing and the requirements of teaching experiment in detail,Based on a comprehensive review of the status of the development of automated teaching platform and the practice of mineral processing automation engineering,2.This thesis puts forward the modeling methods of virtual instruments and virtual valves in the simulation platform,then carries out the overall design of virtual instrument and actuator simulation platform for the whole process of mineral processing.Besides,This thesis conducts a detailed design and discussion of manmachine interface,model realization,operation management,data communications for the virtual instrument subsystem,virtual valve subsystem,virtual electrical equipment subsystem,which can achieve data management of instruments,valves,electrical equipment in the case of single equipment and automation projects and thus carries out simulation teaching experiment.3.based on C++/MFC,this thesis develops virtual instrument and actuator simulation platform of case-oriented teaching,including OPC client,Ado communication module,instrumentation module,valve module and electrical equipment module.4.Finally,this thesis taking a certain ore dressing plant automation project as the simulation operation object to verify the whole process of virtual instruments and virtual actuator simulation platform proposed in this thesis.The results show that with the help of this simulation platform,teachers can demonstrate relevant knowledge about instrumentation,valves and electrical equipment in mineral processing automation engineering and carry out simulation operations for students,which proves the validity and practicability of the platform. |
