Problems solved by technology

[0002] The controller is one of the most important and most difficult instruments for students majoring in automation. At present, there is no teaching instrument specifically for the teaching and training of controllers. Enterprises, schools and Scientific research institutes need many instruments, such as signal sources, controllers, timers, a large number of display instruments and button switches, when conducting teaching and training of controllers. The connection lines are complicated and easy to make mistakes. If the instrument is damaged, students need to be highly concentrated during the operation, which brings a lot of inconvenience to the teaching. Because there is no intuitive teaching instrument, it makes it difficult for students to understand and affects the quality of teaching.
