Problems solved by technology

[0004] The first is a completely real chemical plant, which is usually used for teaching after the original school-run factory shut down due to various reasons. Students can familiarize themselves with the chemical production process in this plant, and can also carry out simulated production However, the device occupies a large area, it is impossible to move it to the classroom, and it is difficult to carry out integrated teaching of theory and practice, and the device cannot feed materials, and everything is in a static state. Students do not have the feeling of chemical production and operation. to the desired effect

[0005] The second type is a completely virtual chemical plant, without any physical objects, everything is carried out on the computer. Its essence is a kind of chemical engineering simulation software. This kind of device does not have any physical input except the computer, and the operating cost is relatively small. Classes in the classroom, in front of the computer, imitate DCS and on-site operation of the device according to the operation steps. Through this training, students can have a more intuitive understanding of the DCS and on-site operation of the device. However, due to the lack of real objects, similar software games

[0006] The third is to build a chemical device in a relatively large classroom. This device generally scales down the production process device of a certain chemical product to make a device model, and then uses simulation software to implement DCS control on the device. The on-site operation to be carried out is transmitted to the computer by the additional signal of the valve. Through this kind of training, the students can have a sense of reality when performing DCS and device on-site operations, and are closer to the real state of chemical production. The raw materials and operating costs are also very small, but because the device is a scaled-down version of the original real device, there is a lack of coordination between the devices as a whole, and some devices are even smaller than the pipeline, making it difficult for students to feel that it is a real device. Chemical equipment, in addition, most of the device frames are made of decorative materials, which greatly reduces the realism of the chemical device, and the simulation software has basically not changed much, and it cannot be the same as the real chemical production, where several operating stations jointly control a device. In production operation, there is no on-site detection instrument, only the same transmitter, which is far from the real chemical plant

However, there are still deficiencies in such devices: first, due to the limited construction space, the scale of the devices is not very large, and it is difficult for students to connect with the actual large-scale production devices; second, there are certain restrictions on the applicable majors, which are only applicable to The training of chemical process, chemical equipment and some automatic control professionals; third, due to the constraints of the scale of the device, it is difficult to implement production practice and enterprise job training
