Thread Content

summary: DCS simulation teaching and real factory practice * Combining simulation device practice with on-the-job practice * Combining simulation training with project construction, DCS simulation * Combined with various competitions, DCS simulation plays a positive role in promoting the operation of chemical industry positions and enhances students' learning of DCS automatic control. * Enthusiasm has greatly enriched and improved the company's demand for talents and reduced the company's training costs for employees. Practical training that combines virtual and real practice is a high-efficiency practical teaching model. After several years of practice, our school uses virtual simulation training combined with project construction, DCS simulation * Combined with various competitions, it improves the efficiency of practical teaching and cultivates students' * Operational skills broaden students' employment opportunities and enhance the school's popularity. 1. Virtual simulation * Hexia Changshi * combined theory * It is abstract and boring. Higher vocational students, especially secondary vocational students, need to improve their academic performance. * Efficiency, enhanced simulation * effect, especially for students who have never seen a real chemical process. * Go to the factory for short-term practice before simulation * is necessary. The 3D simulation software developed by Qinhuangdao Yuandao Technology Development Co., Ltd. adds the structural characteristics of various unit equipment, spatial geometry, process and control system composition, pipeline direction, valve size specifications and positions, etc., which is a good way for our school to omit the actual work in the factory. * many troubles. On this basis, simulation training is carried out, and instructors and company technical personnel organize students to conduct analysis and comparison to further deepen students' learning. * Impression, thereby cultivating students to master the application and adjustment technology of complex control systems, improve their analysis and decision-making capabilities for the dynamic operation of complex production processes, and thereby master the characteristics and operating methods of chemical product production. 2. Simulation Devices and Topics * Relatively qualified schools have established simulation devices similar to chemical engineering. For example, our school has established a distillation device that can simulate industrial production devices and reproduce most of the conditions of industrial production. It can distill 15% ethanol aqueous solution and recover 92% of the complete DCS operating system, fully reflecting the entire process of starting, normal operation, and parking. With the simulation device combined with the simulation system, the parameter changes of the simulation system are designed based on a certain mathematical model. Through the simulation system and the correspondence with the simulation device, learning is deepened. * Understanding of theoretical knowledge. 3. Combining DCS simulation training with project construction. Teachers must go deep into the enterprise and conduct practical exercises in production positions for a long time to accumulate work experience, improve teachers’ quality and ability to implement engineering education, and ensure that teachers can provide high-quality “engineering education and innovation education” to students when implementing engineering education oriented towards production practice. The school-enterprise cooperation in our school is very impressive, and chemical engineering teachers and students are often organized to go to the factory for practical experience. * , participate in enterprise project construction. 4. DCS Simulation * Combined with competitions, students participate in skill training, skills appraisal, and then participate in skills competitions, which reflects the growth pattern of students from novices to experienced hands, and then becomes experts, and meets the needs of cultivating high-skilled talents. This is the embodiment of the characteristics of vocational education and the need for talent cultivation. Our school participated in the "National Vocational College Vocational Skills Competition" chemical production technology competition and won the gold medal. This is the result of our school's promotion of curriculum reform, professional construction, integration of majors and industries, connection of course content and professional standards, and connection of teaching process and production process. Further stimulated students’ interest in DCS simulation * The enthusiasm of students has cultivated high-quality skilled professionals who can adapt to the development needs of the chemical industry, enhanced the social recognition of vocational education, promoted the development of vocational education, and enhanced the social service capabilities of vocational education. DCS simulation plays a positive role in promoting the operation of chemical engineering jobs and enhances students' learning of DCS automatic control. * Enthusiasm has greatly enriched and improved the company's demand for talents and reduced the company's cost of training employees. This fully demonstrates that the practical training room that combines virtual and real practice is a highly effective practical teaching model.
