Taking ZC8800/20/38 solid filling hydraulic support as the research object,the automatic control system is designed in combination with the actual situation.There are stand controllers in the system,which serve to collect sensor data and control the hydraulic stand at the same time.Each bracket controller interacts with each other and with the downhole host using RS485 bus.The downhole host computer is connected to the main control computer on the ground using a switchboard.The stent controller model is S7-200 PLC controller.As for the software program,it focuses on the automatic control of falling material and the control process of pushing and compacting mechanism.The automatic control system has been debugged on the ground,tested in the underground industry and applied in the industry,and it is found that the overall operation is stable and achieves the expected effect,with significant safety benefits and economic benefits.
