Online engineering system and method for control engineering

The invention relates to an online experimental system and method for controlling engineering, in particular to a learning, testing and experiment for a user to use a network communication at a remote end to perform related control engineering, not only during the experimental operation, but also without time and The limitation of space can reduce the huge expenditure on the equipment of the school unit, fully realize the effect of making the best use of the material, bring the user convenience in learning, and at the same time improve the interest of the user and increase the authenticity of the internship. An innovative designer of online experimental systems and methods for control engineering that has increased utility characteristics in its overall implementation.

According to the control engineering experiment, it is a compulsory course for the departments of electrical engineering, mechanical engineering, aerospace, and chemical engineering. Its purpose is to strengthen the students' study of the control engineering curriculum, in order to achieve the education of both theory and practice. However, the control engineering experimental equipment often prices It's very expensive, so the average school can't afford this huge expense, not to mention the cost of maintenance and repair is astounding.

In addition, with the development of network communication and even cloud technology, the communication of knowledge is not only fast and convenient, but also far-reaching, and the communication of educational knowledge has also undergone fundamental changes in this environment; in recent years, the Ministry of Education has promoted the Internet far. There have been preliminary results in teaching. The so-called distance teaching includes synchronous (instant group broadcasting) distance teaching and non-synchronous distance teaching. Synchronous distance teaching is taught outside the main teaching classroom. The video classrooms provide students from both places to attend classes at the same time; instead of synchronous distance education, there is a teaching platform and network system software to store or build the teaching courses on the Internet for students to download and learn. Because the distance teaching method can effectively save teaching resources and provide students with convenient ways to learn anytime and anywhere, the distance teaching method has become one of the trends of future teaching.
