“…The electro-hydraulic servo valve drives the motor through current, and the motor drives the baffle to rotate, causing the oil pressure at both ends of the spool valve to be different, which further causes the spool valve to move and output a certain amount of oil [18]. Two relationships-the relationship between the current and the displacement of the spool valve and the relationship between the spool valve removal and the output oil volume-are mainly…”

A physical modeling approach was adopted to build a Digital Electro-Hydraulic Control (DEH) system simulation model and the fault models using the SIMULINK tool. This research combined the advantages of the gray system and neural network to build a multi-parameter gray error neural network fault prediction model for the first time. Furthermore, an embedded platform for intelligent fault diagnosis and prediction was developed using an Application Specific Integrated Circuit chip. The results show that the simulation model of the DEH system has good performance. A jam fault, internal leakage, and a device fault could be accurately identified through the fault diagnosis model. The multi-parameter gray error neural network prediction model improves the accuracy of fault prediction. The embedded platform developed by the Application Specific Integrated Circuit chip solves the problem of transmission limitation and insufficient computing power. It realizes the intelligent diagnosis and prediction of DEH system faults and guarantees the regular operation of the DEH system.

In order to adapt to the development trend in current vocational education, we developed a multi-functional hydraulic test bench for mechatronics teaching practice. The component structure and functional features of the test bench was introduced in this paper and the application to vocational education was proved to be effective. Practice shows that the bench not only provides students with good experimental conditions close to the actual production and inspires learning enthusiasm and innovation consciousness of the students, but also provides teachers with a platform for scientific research, improves the utilization value of equipment.
