Figure 1 , 2As shown, it includes a hydraulic power module 100, a PLC control module 200, a valve drive control module 300, a SCADA monitoring module 400, an MQTT communication module 500, an alarm and interlock module 600, a modular expansion interface module 700, and a remote control system 800, wherein:
[0027] The hydraulic lines of the hydraulic power module 100 are connected to the valve actuator of the valve drive control module 300 via quick couplings, providing the hydraulic power required to drive the plug valve. The hydraulic power module 100 is electrically coupled to the input terminal of the PLC control module 200 via a cable. The output terminals of the PLC control module 200 are electrically coupled to the relays and the hydraulic station's electrical control components. The PLC control module 200 is electrically coupled to the SCADA monitoring module 400 via an Ethernet port. The PLC control module 200 is installed in the control cabinet and is used to control the start and stop of the hydraulic station and the hydraulic circuit. The system monitors the on / off state and the opening and closing action of the plug valve; the SCADA monitoring module 400 communicates with the PLC control module 200 via the AB protocol and is used to collect real-time operating data of the hydraulic station and plug valves; the MQTT communication module 500 is used to upload the data collected by the SCADA monitoring module 400 to the cloud server of the remote control system 800; the alarm and interlock module 600 is integrated and installed in the control cabinet panel or in a dedicated alarm module; the modular expansion interface module 700 is connected to the PLC control module 200 via an internal bus and is used for plug-and-play management of multiple plug valves.

The hydraulic power module 100 is driven by the PLC control module 200 and receives sensor feedback.
[0029] It should be noted that the PLC control module 200 includes a main control CPU, a power supply module, input / output modules, analog quantity modules, and expansion modules; these modules are arranged and mounted via DIN rails. All modules are linked and controlled around the PLC control module 200 as the core control unit. The PLC control module 200 controls the switching of the hydraulic circuit through relays.
[0030] It should be further explained that the hydraulic station supports both manual and automatic working modes; in manual mode, the energy is stored manually and the start and stop are controlled manually; in automatic mode, a pressure threshold is set, and the motor is automatically started when the pressure is below the lower limit and automatically stopped when the pressure is above the upper limit.
[0031] It should be noted that the SCADA monitoring module 400 includes an HMI touchscreen, an industrial control computer, and a SCADA software platform; the HMI touchscreen and the industrial control computer are respectively installed on the operation panel or console of the control device.

These slots, ports, and modules are respectively located on the side panels of the control cabinet and hydraulic station, used to expand multiple high-pressure plug valve control units, and support plug-and-play arrangement and rapid deployment. The modular expansion interface module 700 connects to the main system using a unified standard interface, achieving a complete closed loop of control channels and data flow.
