Aiming at the shortcomings of current hydraulic component courses and experimental methods, a theoretical teaching and experimental system for hydraulic components was designed based on the internet and campus network system.By the system, the theoretical teaching and experimental system of hydraulic component courses in the school headquarters and the new campus could be combined organically, as well as colleges and universities across the country.By the system, the traditional teaching and experimental mode could be changed, a completely new theoretical teaching and experimental mode of hydraulic component courses was opened up. In any place covered by network signal, teachers and students could realize on-site and remote visual theoretical teaching, experiment and learning through the queuing application management system of the test rig. Performance teaching experiments for multiple hydraulic components could be carried on by the test rig through servo control and manual operation.
