3. System Innovation Points
Break the inequality of educational resources between schools or enterprises, and realize the integration of resources of all parties. Through the channel and means of the Internet, various barriers are broken, so that every student can learn professional knowledge such as chemical engineering in a three-dimensional manner.
A system for large-scale online learning of professional knowledge such as chemical engineering is an online education model that any student can use. An evaluation system and assessment method similar to offline simulation software is adopted. The platform starts classes on a regular basis, and the entire learning process includes watching videos, theoretical learning, participating in discussions, test questions, online simulation operations, and more.
Each course has its own learning standards, and the courses include: theoretical study, material viewing, simulation operation, and exercises. The system can comprehensively record the student's learning status, record the theoretical study time, record the results of the number of exercises, and record the results and duration of the simulation operation. Allow teachers to observe students' learning outcomes in a three-dimensional manner.

4.1 Platform Home
After students log in to the platform, they enter the home page of the system, which mainly displays popular simulation courses and simulation courses recommended by the system. Each course displays user ratings with stars, so that users can see the gold content of the courses more intuitively.
4.2 Simulation course learning
Take a distillation column as an example to introduce how to study a course
Click on the "Distillation Column" course to enter the learning state. The renderings are as follows:
4.3 Theory course study
The theoretical course refers to the course knowledge carried out from the shallower to the deeper in the form of chapters. Students can click on any chapter to study the text of the course:

5. Function and significance of simulation software
5.1 Realization function and significance
On the premise of safety, reduce the number of times the device is opened and stopped
Operational training in a safe environment
Simulate accident phenomena and accident handling in a safe environment
Implement control system response and performance analysis
Safe and fast evaluation of operating procedures
5.2 Skill training for technicians and operators
1. New equipment start-up training:
The simulation system can realistically simulate the phenomena and operations of the plant's start-up, shutdown, normal operation and various accident processes. Since operators and process technicians can pre-train and study the start-up and shutdown of new plants in the simulation system, it will lay the foundation for a successful start-up of the plant. DCS training for operators in the simulation system can make operators familiar with DCS operation in advance, shorten the adaptation period of operation habits, and ensure the normal start-up of production equipment.
2. Skills training for on-the-job personnel:
The simulation software can regularly conduct skill training for the on-the-job operators, allowing the workers to simulate starting and stopping and various accident operations on a regular basis, so that the on-the-job personnel's sensitivity to the operation of the device has been maintained at a high level.
3. Cultivate the backbone of skills:
Each production workshop hopes that more operators can master the operation skills of multiple positions (system operators with one person and multiple positions). However, due to factors such as the requirements for stable production of the device and the division of responsibilities, it is difficult to cultivate the operation skills of one person and multiple positions in the actual production process. On the simulation system, the training of operation skills for one person and multiple positions can be organized in a planned way. For example, the simulation system is used to train the operators in the response positions for separation of positions, so that they can master the operation skills of separation positions.
4. Skills training for transfer personnel and new employees:
On the simulation system, skill training is carried out for the transfer personnel of the enterprise or the new workers and technicians, so that the new employees can master the operation of the device as soon as possible.
5.3 Plant production safety analysis and accident training
Safety and training The custom support system can define and set up various accidents in the developed device simulation system. These accidents can be happened before, or they can be "hypothetical" possible accidents by production technicians. All settings Accidents can occur in the device simulation system and simulate various corresponding process phenomena. When different processing methods are used, the simulation system can realistically simulate the corresponding process phenomena and the entire dynamic process of the device, which can be used for device production technology. A simulation test platform for personnel to conduct safety analysis of device production, test accident cases and find reasonable accident treatment plans.
5.4 Device design inspection and production guidance functions

For new plants, the simulation training system can verify the feasibility of its process and operation plan.
(2) Design inspection of control scheme and interlocking system
The simulation system can test the control system scheme of the new device to check its rationality and feasibility, and can debug the PID parameters of the device control loop on the simulation system. The simulation system can test and verify the interlocking system of the new device and its logical relationship.
2. Application in device production guidance
(1) Test and optimization of the start-stop operation plan
On the simulation training system, the operation test is carried out according to the pre-designed driving or parking plan, and the feasibility and effect of the operation plan are tested, such as: driving time, energy consumption, etc. Find out a more reasonable and optimized start-up and shutdown plan for the device.
(2) Serve for production preparation
Material and heat balance calculations are performed during system development. The material and heat imbalance problem found in this process will be notified to the user in time, so that the problem can be solved as soon as possible; the development of the simulation system will also carry out strict equipment simulation calculation, which will be strictly based on the user's equipment data. The production capacity of the equipment, the mismatch between the pipe and the valve size will also be notified to the user in time. The timely solution of the problems found in the above process will provide help for the normal driving of the device.
(3) Operational guidance for production adjustment
On the simulation training system, the operation test is carried out according to the pre-designed raw materials and other conditions, and the appropriate operation plan is found to ensure the production of qualified products by the device, or the feasibility of the production conditions, such as: the adaptability of raw materials and their smooth operation adjustment plan, Plant load and its "bottleneck", etc. The dynamic characteristics of the device are studied through the simulation system experiment to provide guidance for the device operation.
