The hardware-in-the-loop simulation teaching system is an innovative product, which is a combination of software and hardware used in scenario training. Through the software simulation of production data, combined with the operation of training equipment, the actual production process of the factory is reproduced to serve the education industry. Different from the traditional physical training device, it adopts advanced process simulation software to drive the physical device, and combines the latest intelligent transmitter technology, detectable manual valve technology, sound and light technology, field bus technology and embedded screen display technology , so that the trainees can vividly feel and contact the environment and operation of the real factory.

The hardware-in-the-loop simulation system consists of four parts: OTS simulation system, practical training device, control system and electrical instrument system and safety factor system. The real industrial DCS software is used in the control system, which is seamlessly integrated with the OTS system, which is closer to the actual operation; the actual operation training device is combined with the simulation software, and the real factory is simulated on the simulation software, and the real-time interaction device with the process device does not carry out production. Transmitter and control instrument signals are provided by simulation software; practical training equipment can also simulate processes that cannot be carried out by other products such as high temperature and high pressure reaction, and can be processed by profile, sight glass, etc., so that trainees can fully understand the factory equipment Internal structure and working principle; the risk information of corresponding equipment and "materials" is added to the system, and the relevant risk safety elements are integrated into the training device. While learning chemical operations, you can understand the content of safety elements.
