Abstract:In the complex battlefield environment, for the hydraulic system used in military weapons, equipment and facilities, good fight attack capability is required with high reliability and fast diagnosis ability to repair. A simple and highly efficiency distributed teaching and assessment platform was realized with the technology of PLC, Ethernet network, configuration software etc. The experimental objects of this platform were the basic circuits containing hydraulic pump, relief valve, reversing valve, filters and other components, using hierarchical ladder type structure. The platform can be used to realize daily training and assessment.
