Description

Technical Field

[0001] This invention relates to the field of electro-hydraulic control technology, and in particular to a backup management method for the functional parameters of an electro-hydraulic control system. This method is applicable to the parameter management of the electro-hydraulic controller of a network-type hydraulic support in a fully mechanized coal mining face, and can achieve efficient backup, accurate recovery, and refined management of the functional parameters of the electro-hydraulic control system under complex working conditions. Background Technology

[0002] In fully mechanized coal mining operations, the electro-hydraulic control system, as the core control unit, needs to handle various working conditions and contains a vast number of functional parameters. Modern fully mechanized mining faces are typically equipped with various frame types, such as intermediate frames, end frames, transition frames, and advance supports. The functions of the electro-hydraulic directional valve groups differ significantly among different frame types, and their corresponding parameter configuration systems also vary. When the working conditions of the face change or equipment operates in coordination, the controller parameters need to be precisely configured.

[0003] Traditional parameter management methods rely on repeated manual settings, which are cumbersome, time-consuming, and prone to human error, severely impacting production efficiency and equipment stability. Existing parameter backup management solutions also have many shortcomings and fail to meet actual needs: some solutions rely on physical media insertion and removal for backup, which can easily damage interfaces in the humid and dusty underground environment, resulting in poor connection stability and a high risk of data loss; furthermore, they only support manual operation on-site, leading to extremely low overall operational efficiency for workfaces with dozens or even hundreds of supports, making them unsuitable for centralized management, and lacking a backup status feedback mechanism, preventing users from confirming backup success in real time and posing hidden data security risks.

[0004] While other solutions propose a general parameter management approach based on backup strategies, they fail to adapt to the specific characteristics of electro-hydraulic control systems. They lack a "frame type-parameter" association mechanism, making it impossible to distinguish the unique parameter sets for different frame types, leading to parameter confusion in multi-frame working faces. Furthermore, version management only records backup time, not parameter change details, making it difficult for users to quickly pinpoint the root cause of problems and achieve accurate recovery when parameters are abnormal. Additionally, some solutions, while supporting remote operation, lack encrypted data transmission and dual storage protection, making them prone to data leakage or loss in complex communication environments. With the application of distributed operating systems in fully mechanized mining equipment, the demand for inter-device interconnection is increasing. However, existing solutions have not formed a collaborative management system with the host computer and cloud, failing to meet the centralized monitoring and data sharing needs of intelligent mining. This makes it difficult to address the core pain points in parameter management of electro-hydraulic control systems in fully mechanized coal mining faces: insufficient specificity, low operational efficiency, difficulty in version tracing, and poor data security. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a backup management method for the functional parameters of an electro-hydraulic control system. This method solves the problems of backup relying on physical operation or manual triggering, lack of targeted parameter management, difficulty in version tracing, and insufficient recovery adaptability in the prior art, thereby improving the efficiency, safety, and accuracy of parameter management in the electro-hydraulic control system.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a backup management method for functional parameters of an electro-hydraulic control system. It establishes a complete parameter backup management system by constructing a rack type management module, a file system interaction module, a parameter backup module, and a parameter recovery module. Specifically, the rack type management module establishes a "rack type-parameter" association mechanism to achieve parameter management categorized by rack type; the file system interaction module provides support for the storage and cleanup of backup files; the parameter backup module supports encrypted dual-storage backup triggered by multiple methods and generates version change records; and the parameter recovery module achieves accurate recovery through rack type verification and parameter ID matching, ensuring the targeted and reliable nature of parameter management.

[0007] According to the backup management method for the functional parameters of the electro-hydraulic control system provided by the present invention, the frame type management module can automatically filter the parameter set corresponding to the target frame type when switching working conditions, thereby avoiding confusion of parameters of different frame types from the source, laying the foundation for the accuracy of subsequent backup and recovery, and is applicable to complex scenarios with multiple frame types in coal mine fully mechanized mining faces.

[0008] According to the backup management method for the functional parameters of the electro-hydraulic control system provided by the present invention, the parameter backup module supports three triggering modes: manual, timed automatic, and remote command. It does not rely on physical medium plugging and unplugging operations and is suitable for unattended operation or centralized management of multiple supports in underground environments. The backup files are named according to "precise timestamp + support type name + intraday serial number". Combined with the automatically generated version change record, it can achieve clear differentiation of versions and traceability of historical changes, thus solving the problem of chaotic backup versions in traditional systems.

[0009] According to the backup management method for the functional parameters of the electro-hydraulic control system provided by the present invention, the parameter backup module uses industrial-grade encryption to synchronize the parameter and version change records to dual storage on the local support controller and the upper computer cloud. If the synchronization fails, it will retry 3 times and alarm, and at the same time, the backup status will be fed back to ensure the security of data transmission and storage, avoid data loss or leakage, and solve the problem of low backup data security in the prior art.

[0010] According to the backup management method for the functional parameters of the electro-hydraulic control system provided by the present invention, the parameter recovery module automatically verifies the matching between the backup file frame type and the current frame type before recovery. If the verification fails, the operation is terminated and a prompt is displayed. After the verification passes, the system parameters are updated by accurately matching the parameter ID. After completion, the recovery result is fed back and the operation log is recorded, thereby improving the accuracy and reliability of the recovery process and avoiding equipment failure caused by parameter mismatch.

[0011] According to the backup management method for the functional parameters of the electro-hydraulic control system provided by the present invention, the file system interaction module automatically cleans up expired backup files and retains only the most recent preset number of valid versions, thereby avoiding waste of storage resources and ensuring that users can trace recent key versions, thus balancing storage efficiency and version traceability requirements.

[0012] The backup management method for functional parameters of the electro-hydraulic control system provided by this invention achieves precise parameter classification, automated and remote backup triggering, structured version management, and precise recovery process through the coordinated work of four modules. It effectively solves the shortcomings of the prior art, significantly improves the efficiency and safety of parameter management of the electro-hydraulic control system in coal mine fully mechanized mining faces, ensures stable equipment operation, and reduces production risks caused by parameter configuration problems.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] This embodiment uses a multi-frame electro-hydraulic control system for a fully mechanized coal mining face as an application scenario, combined with the attached... Figures 1 to 4 Each module focuses on a different backup-recovery triggering method, explaining the collaborative workflow of the four modules and presenting a standardized implementation process for parameter backup, storage, and recovery.

[0020] [First Example: Manually Triggering the Entire Backup-Restore Process] This embodiment triggers parameter backup and recovery via local button operation on the support controller, suitable for on-site personnel to quickly handle the parameter management needs of a single or small number of support structures. Figure 1 Method 1 Figure 3 Method 1 Figure 2 and Figure 4 The specific process is as follows: S1: The rack management module has pre-completed the "rack type - parameter" association configuration. The exclusive parameter set of each rack type has been mapped, and each rack type is assigned a unique identifier.

[0021] S2: The operator presses the "Backup" button on the support controller, selects the current support frame type, and triggers the parameter backup module to generate a backup control command. After receiving the command, the parameter backup module retrieves the set of sensor parameters and process parameters corresponding to the intermediate frame from the frame type management module, obtains the current operating parameters, compares them with the previous version, and generates a change record.

[0022] S31: Generate a backup file in the format "YYYYMMDD - Target rack type - Daily serial number", encrypt it with industrial-grade encryption, and then synchronously store it in the local storage area of ​​the rack controller through the file system interaction module.

[0023] S32: The file system interaction module records the backup time and subsequently retains the most recent N versions according to preset rules, while automatically cleaning up expired files; after the backup is completed, the bracket controller screen displays "Backup successful" and provides status information.

[0024] S41: The operator presses the "Restore" button on the bracket controller, selects the target version from the local backup file list, and the parameter recovery module generates a restore control command.

[0025] S42: The file system interaction module reads the corresponding backup file according to the instructions, and the parameter recovery module parses the frame type identifier in the file header and performs a consistency check with the current frame type.

[0026] S43: If the verification passes, the abnormal parameter is accurately matched by the parameter ID; if the verification fails, the operation is terminated and the "Frame type mismatch" prompt is displayed.

[0027] S44: After the recovery is completed, a "Recovery successful" message is sent, and the operation log is recorded and uploaded to the host computer. The log is retained for a preset number of days for traceability.

[0028] [Second Implementation Example: Remote Command Triggered Backup-Restore Process] This embodiment triggers batch parameter backup and recovery of multiple support frames by issuing remote commands from a host computer. It is suitable for centralized management scenarios on the work surface. Figure 1 Method 3 Figure 3 Method 2 Figure 2 and Figure 4 The specific process is as follows: S1: The host computer administrator selects the full-work-surface support or a specified support through the centralized monitoring platform and issues a remote backup command. After receiving the command, the target support's frame type management module automatically filters the parameter set corresponding to the target frame type to avoid confusion with parameters of other frame types, and synchronously feeds it back to the parameter backup module.

[0029] S2: The parameter backup module generates backup control commands, batch obtains the operating parameters of all target rack types, generates independent backup files for each rack, and generates version change records for each rack.

[0030] S31: Employs industrial-grade encryption technology to store the backup file of the target bracket type in the corresponding local storage area. At the same time, the target backup file and change records are synchronously stored in the host computer cloud storage area, achieving dual local and cloud storage. If synchronization fails, it will retry at a preset interval. If it fails 3 times in a row, an alarm will be triggered, the bracket controller indicator light will flash, and a pop-up window will appear on the host computer.

[0031] S32: The file system interaction module categorizes and stores backup files in the cloud, and the host computer's dedicated interface displays the backup time, rack type, and change details of each file, supporting quick queries; the local storage area cleans up expired files according to rules and retains the most recent preset versions.

[0032] S41: When the host computer detects abnormal parameters of multiple target rack types, it selects a historical normal backup version, issues a remote restore command, and specifies the rack type to be restored and the backup file.

[0033] S42: After receiving the instruction, the parameter recovery module reads the target backup file from the cloud through the file system interaction module, parses the rack type identifier of each file one by one, and verifies it with the corresponding rack.

[0034] S43: For stents that pass the verification, the parameters are updated accurately using the parameter ID; for stents that fail the verification, a separate "stent type mismatch" message is provided, without affecting the recovery process of other stents.

[0035] S44: After the full recovery is completed, the host computer receives the summary of the recovery results of each support, generates a batch recovery report, and records the operation log of each support, supporting batch export and traceability.

[0036] [Third Example: Scheduled Automatic Backup-Manual Restore Process] This embodiment automatically triggers backups at preset time intervals, combined with manual recovery, making it suitable for parameter security assurance in unattended scenarios. Figure 1 Method 2 Figure 3 Method 1 Figure 2 and Figure 4 The specific process is as follows: The support controller has a preset automatic backup time interval. After the preset time is reached, the system automatically activates the parameter backup module and generates backup control commands. The support type management module filters the corresponding support type parameter set according to the current working conditions.

[0037] The parameter backup module acquires relevant parameters of the target rack type in batches, generates backup files and change records, encrypts them, and synchronizes them to local and cloud dual storage areas. The synchronization status is fed back to the host computer in real time.

[0038] The file system interaction module regularly cleans up expired files to ensure sufficient storage resources, and the version list is automatically updated in the cloud, supporting the tracking of historical versions.

[0039] Operators can manually trigger the recovery via the bracket controller, selecting a historical normal version from the scheduled backup.

[0040] The parameter recovery module completes rack type verification, parameter matching and updating according to the process. The recovery process is consistent with manual trigger recovery, and finally the results are fed back and recorded in the log.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
