Design And Application Of The PLC Educational Experiment System

Principle and application of the programmable logical controller is an important work to control the foundation lesson, the principle of programmable controller is abstract, however, the application of programmable controller tightly combines to the process of production. The practice teaching is possessed of larger proportion in this course.Teaching of programmable controller is not only to teach students the theory, but also to enhance the training of their practical ability.By the practice teaching, students not only comprehend the programmable controller's theory, but also mastery the advanced control technology. And better teaching effect can be reached.Research of a new imitate control board for the teaching on PLC in this paper-----teaching of PLC imitates the plank that control the teaching useds for the PLC experiments, the core of the system is SIMATIC S7-200 series. This experiment system is designed for improving the students' skill of developing products, and it remains enough space for students to extend its application. The experiment system includes a number of backup instruments, and the PLC also has spare logic elements to help students to extend it to an actual industry cycle with an additional programming. With the development of the electronic technology, it has the capability to be updated by adding buttons, logic elements and modules to fit new experimental requirements in future.This paper introduced the total project of control system based on PLC practice teaching.A design at hardware and software and realize the net communication to a new imitate control board for the teaching on PLC are explained in detail. Take simulation control board for material automatic transfer system as an example,the application of a new imitate control board for the teaching on PLC are described. Make use of the function of PLC programming and debugging system.Application of PLC in automatic control of electrophoresis in cantilever-line is explored. We have put forward a automatic control system for the experiment elevator control system basins on confinuration technolony design of MCGS.
