In the field of vocational education, practical training teaching has long faced numerous complex issues; for example, teachers have a heavy workload when explaining things to multiple students at once, and students find it difficult to understand theoretical knowledge； Training equipment is expensive, and schools cannot afford to purchase it without condition; moreover, the limited number of such devices means that it is not possible to meet each student’s needs for practical training, and the safety levels associated with these training activities are low ； The practical training teaching and assessment system is incomplete ； The tasks at off-campus training centers have nothing to do with the teaching content on campus, and so on. To address these challenges, Qinhuangdao Yuandao Technology Development Co., Ltd. established a simulation training factory. Virtual simulation training systems integrate information technology with vocational education. Centered on practical training, they create networked and virtual training environments that overcome physical space limitations by combining school laboratories with corporate factories through network technology to form a \"virtual space\" that transcends time and space, utilizing high-performance computers to generate a virtual factory. Virtual simulation training systems are used for teaching and training in universities and petrochemical enterprises. It is mainly used by higher vocational students majoring in chemical-related fields to learn internal operations, external operations, and coordinated internal and external operations in chemical plants. It is also utilized for training new employees in petrochemical enterprises, as well as for retraining and cross-training existing employees. Teaching Objectives: 1. Address the issue of inability to conduct practical operations during trainings for students. 2. Improve the efficiency of student training. 3. Solve safety problems related to student training. 4. Overcome difficulties in allowing students to access training sessions. Main Functions: Safety template – Provides safety instructions to students before practical training, helps foster a sense of safety, and facilitates the resolution of safety hazards ； Knowledge modules – present relevant knowledge points through video animations and on-site annotations, in a clear and intuitive manner that helps learners organize their thoughts ； Access knowledge points anytime and resolve difficult issues quickly ； Training module – a virtualization-based training environment that accurately replicates real training scenarios, offering a realistic and safe experience with immersive VR interaction to enhance students’ interest and deepen their understanding ； Assessment module – Automatic evaluation of the practical training assessment process, real-time monitoring of learning outcomes, and reduction of teachers’ workload ； Statistics module – custom statistical analysis for more comprehensive teaching management and more intuitive teaching data. Product advantages: Task-based teaching approach – It integrates the principles of task-based teaching in a systematic manner, enabling it to stimulate, enhance, and sustain students’ sense of achievement, thereby increasing their enthusiasm for completing practical training tasks. Immersive experience, interactivity, and roaming capabilities – The system utilizes VR virtual simulation technology to create complete operational scenarios, applying real-world task examples to practical training. The strong sense of immersion and involvement enables students to quickly assume their roles and successfully complete their learning tasks driven by those tasks. Please incorporate strong interactivity and roaming features to make students feel as if they are on the scene, thereby enhancing their learning experience. Supports personalized design of training tasks – The system not only provides standard training tasks for use by enterprises or teachers, but also allows them to customize these tasks to create training activities suitable for teaching, thereby meeting the training needs of enterprises and teachers. Automatic evaluation of the learning process – The system automatically scores the learning and training process based on the student’s actions, thereby reducing the workload on teachers and helping them to clearly understand the results of the students’ training. Development of the first version of this system began in 2009; the first version of the software was sold in 2012. In 2013, the copyright for the \"Yuandao DCS Process Simulation Software\" platform was applied for and obtained. Over the course of more than 10 years, feedback from customers led to continuous modifications and upgrades – a total of around 49 upgrades were carried out, including 4 major version upgrades that involved completely overhauling the software architecture, and 49 minor version upgrades. It is a mature, stable, and feature-rich chemical process simulation training software in the industry.
