This system enables intelligent operation of the entire process of coal mine development, mining (stripping), transportation, ventilation, washing and beneficiation, safety assurance, and operation management, ultimately achieving improved safety, reduced manpower and increased efficiency, and energy conservation and consumption reduction in mine production.

[0003] The complete set of equipment for a fully mechanized mining face mainly includes an information sensing system, hydraulic support group, coal mining machine, transportation system, and hydraulic supply system. Each component establishes a data link through industrial fieldbus, Ethernet ring network, etc., enabling remote control from the ground, centralized control in the roadway control unit, and local control of the equipment. The hydraulic support mainly consists of load-bearing structural components, actuators, control and control elements, auxiliary devices, and transmission medium. The load-bearing structural components include the roof beam, shield beam, and base, which respectively bear the contact and load transmission with the roof, fallen rock from the goaf, and the floor. The actuators are mainly columns and jacks, which achieve basic actions such as raising, lowering, pushing, and moving the support through high-pressure hydraulic fluid. Control and control elements, such as control valves and safety valves, are responsible for controlling the hydraulic system's oil circuits and ensuring the safe and reliable operation of the hydraulic actuators.

[0004] The existing electro-hydraulic control system cannot assist maintenance personnel in quickly locating the problem, resulting in reduced maintenance efficiency. Utility Model Content

[0005] To address the problem that current electro-hydraulic control systems for hydraulic supports cannot assist maintenance personnel in quickly locating components, this invention provides an electro-hydraulic control system for hydraulic supports.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] An electro-hydraulic control system for hydraulic supports includes an operating system connected to a detection and control module, which in turn is connected to an action execution module. The action execution module is connected to a support group, which comprises several hydraulic supports. Each hydraulic support is equipped with a sensor assembly, which is connected to a self-diagnostic display. The self-diagnostic display is connected to an audible and visual alarm. The operating system includes a fault monitoring device, and the self-diagnostic display is communicatively connected to the fault monitoring device. The self-diagnostic display receives information from the sensor assemblies and issues a local warning via audible and visual alarms. It can also remotely display the warning on the operating system via the fault monitoring device. This assists maintenance personnel in quickly locating faulty hydraulic supports, improving maintenance efficiency.

[0008] Preferably, the self-diagnostic display includes a display screen, a data acquisition processor, and a fault communication interface; the data acquisition processor is connected to the sensor assembly; and the self-diagnostic display is connected to the fault monitoring equipment via the fault communication interface.

[0009] Preferably, the detection and control module includes a support controller and a data acquisition unit; the data acquisition unit is communicatively connected to the acquisition processor of the self-diagnostic display; both the support controller and the data acquisition unit are connected to the operating system.

[0010] Preferably, the action execution module includes a hydraulically controlled main valve and a solenoid pilot valve; the operating system is electrically connected to the hydraulically controlled main valve and the solenoid pilot valve through a bracket controller. This facilitates rapid raising and lowering of the column and quick sliding operation.

[0011] Preferably, the hydraulic support includes a support; a hydraulic cylinder is connected to the support; a solenoid valve is connected to the hydraulic cylinder; the solenoid valve is connected to an action execution module; a sensor assembly is mounted on the support; and the solenoid valve is electrically connected to a support controller. The support controller can control the movement of the support group through the action execution module, ensuring coordinated and unified movements. Furthermore, the support controller can control the solenoid valves of the hydraulic support, facilitating individual control of each hydraulic support.

[0012] Preferably, the sensor assembly includes a displacement sensor, four tilt sensors, and a pressure sensor. The tilt sensors can detect the angle of the top beam, the height of the support, and the inclination of the base; the displacement sensors can detect the position of the side support; the pressure sensors detect the pressure of the hydraulic support, and the operating system automatically adjusts the system by analyzing the pressure on the working surface and the column.

[0013] As can be seen from the above technical solutions, the advantages of this utility model are as follows: This solution provides an electro-hydraulic control system for hydraulic supports. The self-diagnostic display receives information from sensor components and issues warnings locally through audible and visual alarms. It can also remotely display the fault information on the operating system via fault monitoring equipment, assisting maintenance personnel in quickly locating faulty hydraulic supports and improving maintenance efficiency. The support controller can control the actions of the support group through the action execution module, ensuring coordinated and unified actions. Furthermore, the direct controller can control the solenoid valves of the hydraulic supports, facilitating individual control of the hydraulic supports. Attached Figure Description
