DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0018] Figure 1 The flowchart of the data expression and interaction method of the hydraulic support and control system provided by the embodiment of the present invention is as follows: Figure 1 As shown, the data expression and interaction method of the hydraulic support and control system provided by the embodiment of the present invention includes: Step 101: Collect real-time data of the entire life cycle of each device in the hydraulic support and control system; Step 102: Convert the full lifecycle real-time data into a structured XML document based on the XSD constraint format; Step 103: When the network is normal, the structured XML document is transmitted to the control system in real time based on the transmission protocol; Step 104: When the network is disconnected, the structured XML document is stored locally in the hydraulic support controller.

[0019] Due to the problem of untimely interaction, traditional hydraulic support and control system equipment interaction methods are unable to provide equipment operating condition data storage and interaction support when implementing control systems for unmanned mining in underground mines where the network environment is sometimes unavailable, which restricts the development and application of underground AI control systems.

[0020] The hydraulic support and control system data expression and interaction method provided by the embodiment of the present invention collects the real-time data of the entire life cycle of each device in the hydraulic support and control system; converts the real-time data of the entire life cycle into a structured XML document based on the XSD constraint format; when the network is normal, transmits the structured XML document to the control system in real time based on the transmission protocol; when the network is interrupted, the structured XML document is stored locally in the hydraulic support controller. The present invention proposes a technical solution of local storage + real-time interaction based on XML for unstable working conditions of underground networks through a unique hydraulic support system data expression content format, a unique XML storage interaction method, and a unique hydraulic support control system device interaction method, thereby supporting the storage and interaction needs of equipment working condition data when the AI ​​system is used for unmanned mining in underground networks where the network environment is sometimes unavailable.

[0021] Based on any of the above embodiments, the collection of real-time data of the entire life cycle of each device in the hydraulic support and control system includes: Step 201: sort out the full life cycle data items of each device in the hydraulic support and control system, wherein the full life cycle data items include procurement, installation, commissioning, use, maintenance and scrapping; Step 202: Collect real-time data of the procurement, installation, commissioning, use, maintenance, and scrapping stages, and formulate a unified data organization structure based on the real-time data; Step 203: Write an XSD constraint format document based on the data organization structure.

[0022] In an embodiment of the present invention, the XSD constraint format of the XSD constraint format document includes: Existence constraints on data items; Update frequency constraints for dynamic data fields; Data type constraints, including character, integer, and timestamp formats; Data hierarchical relationship constraints define the parent-child node structure of device information.

[0023] In this embodiment of the present invention, a unified data organization structure is established to achieve unified data expression. This ensures that heterogeneous data, such as hydraulic support mechanical parameters such as pressure and height, electrical parameters such as controller status, and environmental data such as roof pressure, are uniformly formatted, eliminating data silos. This improves data compatibility and avoids parsing errors caused by confusing data formats.

[0024] Based on any of the above embodiments, transmitting the structured XML document to the control system in real time based on a transmission protocol includes: Construct the interactive interface between the hydraulic support and the control system based on the THHP protocol; The structured XML document is transmitted to the control system in real time through the interactive interface.

[0025] In an embodiment of the present invention, millisecond-level data interaction is achieved through a lightweight HTTP / REST interface. Compared with the high latency of traditional database storage methods, standardized data expression + HTTP real-time interaction can reduce the latency to <100ms.

[0026] Based on any of the above embodiments, converting the full lifecycle real-time data into a structured XML document based on the XSD constraint format includes: Define the structure, data type and validation rules of XML data interaction storage documents; An XML data interaction storage document is generated according to the XSD constraint format document, and the XML data interaction storage document is used to store equipment status information of the hydraulic support and the control system.

[0027] In the embodiment of the present invention, XML is a representation of XSD. With XSD, there is a fixed XML writing format. XSD can constrain the data structure of the XML text, such as: whether certain data items must exist, whether the data item is character type or integer type, etc. XSD occupies the core position and role of this management method.

[0028] In an embodiment of the present invention, the interactive interface parses the structured XML document through serialization and deserialization methods, and communicates with the hydraulic support controller to update the equipment status in real time.

[0029] In an embodiment of the present invention, the XML data interactive storage document operation function of the hydraulic support and control system equipment status information includes: transmitting the hydraulic support and control system equipment status through the interactive interface developed by the THHP protocol according to actual needs; and supporting the management of the hydraulic support and control system equipment status information, and the management functions include: freely adding, viewing, modifying, and deleting the hydraulic support and control system equipment status information.

[0030] In an embodiment of the present invention, the device includes at least one of a hydraulic support, a controller, a sensor, an electromagnetic driver, a voltage-stabilized power supply, an isolation coupler, a signal converter, and a connector, and each device is identified by a unique identification serial number.

[0031] The expression format of XML data interactive storage document is as follows Figures 2 to 5 As shown, it mainly involves the expression format of the interactive storage document of hydraulic support information 1, controller 2, sensor 3, electromagnetic driver 4, voltage-stabilized power supply 5, isolation coupler 6, signal converter 7, infrared transmitter 8, connector 9, pipeline 10, integral protective cover 11, and converter 12; the XML format constraint document XSD file is as follows Figure 6 As shown, each part of the data contains ordering information, installation information, usage information, maintenance information and scrapping information, and the device is identified by a unique serial number; the development tool for XML data is Altova XMLSpy, which is a powerful XML and JSON editor specially used for designing, editing and debugging enterprise-level applications, and supports multiple standards.

[0032] like Figure 7 As shown, in the software, the XML data document interaction architecture principle is to interconnect and communicate with other underground equipment and each hydraulic support controller through the THHP protocol. The software continuously confirms the XML document information of each device and obtains and parses it through serialization and deserialization to clearly understand the working status of each device, thereby supporting the AI's autonomous unmanned coal cutting. Simultaneously, within a single data management module, data from each module can be added, modified, viewed, and saved. The software has an interactive interface to transmit information about the hydraulic support and its control system. XML documents received from the outside are stored in the database after XSD format verification. It also receives external instructions to extract XML documents that conform to the XSD format.

[0033] like Figure 8 As shown, the three core modules of interaction include: Hydraulic support control system: main control unit, responsible for support status management; Coal mining machine control system: coordinates equipment and executes mining instructions; Document Information Management Center: XML document storage and processing.

[0034] The hydraulic support control system serializes the current equipment status into a binary data stream, prepares it for transmission, and encapsulates the data using the THHP protocol. Upon receiving the data stream, the shearer control system verifies the integrity of the THHP header, deserializes it to restore the XML document structure, parses key parameters, and adjusts the shearer's movements based on the support status. This interactive process demonstrates a reliable underground equipment communication system based on a standardized XML format, addressing the poor readability of traditional binary protocols and the network dependency of database solutions.

[0035] This embodiment of the present invention tracks all data throughout the entire lifecycle, from procurement, installation, use, maintenance, to retirement, using XML documents. This reduces equipment failure rates and lowers maintenance costs. Predictive maintenance can also be achieved, for example, by analyzing historical maintenance records in XML to proactively replace solenoid valves nearing the end of their lifespan. Alternatively, by analyzing pressure trend data in XML, the risk of bracket failure can be predicted.

[0036] This embodiment of the present invention uses an offline storage mechanism. When the network is disconnected, the XML document is stored locally in encrypted form, supporting subsequent synchronization or manual export to ensure zero data loss. Even when the underground network is unstable, the local data caching capability can still be maintained.

[0037] The embodiment of the present invention provides a method for expressing and interacting with hydraulic supports and control systems. By combing through the data items of procurement, installation, debugging, use, maintenance and scrapping of system equipment such as hydraulic supports, controllers, controller software programs, sensors, electromagnetic drivers, voltage-stabilized power supplies, isolation couplers, signal converters and connectors in a fully mechanized mining face, a data organization structure serving the use cycle of coal mining machine system equipment is formulated, and the formulated data organization structure is compiled into an XSD constraint format document; and based on the compiled XSD constraint format document, an XML data interaction storage document is generated; based on the generated XML data interaction storage document, a software for interacting with coal mining machine system equipment in a fully mechanized mining face is developed to realize information interaction between other equipment and the hydraulic supports and control systems, thereby confirming the status of the hydraulic supports and control systems, and for the purpose of unmanned intelligent mining based on AI technology. The XSD constraint document can be used to verify whether the XML document given to the outside or provided by the outside during the interaction conforms to the file format specified by us, thereby ensuring the reliability and interactivity of the XML document, through XML standardized data expression + HTTP real-time interaction + Local storage disaster recovery can realize the storage of equipment operating condition data and support interactive needs when the AI ​​system is used for unmanned mining underground in an intermittent network environment.
