In view of the current price of electro-hydraulic control system， difficult maintenance and poor adaptability to coal mine environment， the overall structure of electro-hydraulic control system of hydraulic support is designed and designed， and its function is described in detail. In addition， the design of the bracket controller and the communication circuit is carried out. The design system can realize the electro-hydraulic automatic control of the hydraulic support well， which is of great significance for the further research and the further development.
