Discussion on the Application of Online Case-based Teaching in the Course of Electrical Control Technology

In order to meet the current online + offline teaching mode of electrical control technology course and further increase students' understanding and participation in the course, this paper proposes a teaching mode of online case-based teaching + online virtual simulation verification + offline experimental verification. For online case-based teaching, it is necessary to do a good teaching design to ensure that the cases are representative, comprehensive and easy to simulate and verify. The simulation software and virtual simulation verification process based on both relay and programmable controller control methods are introduced. Next, the simulation software and virtual simulation verification process based on both relays and programmable controllers control methods are introduced. With the introduction of online case-based teaching, offline lab courses can be arranged more efficiently to enhance students' practical skills.
