Abstract: As the existing controlled objects have shortages such as large size, less function, high maintenance and inflexibility, a portable automatic simulation experimental platform is designed and developed based on Programmable Logic Control (PLC) and industry touchscreen. The platform can be used as the controlled object to complete the design and implementation of control schemes in cooperation with PLC, Distributed Control System and industrial computer. The experimental platform has the characteristics of portability and the combination of virtual and reality. It is small, light and flexibility. It can not only simulate the working process of common controlled objects such as liquid tank, heating furnace and hot water supply, but also have the input and output signals of actual instruments, which can enable students to complete the system connection and realize comprehensive engineering training for students.
