Description

Technical Field

[0001] This invention belongs to the field of communication control system technology, and specifically relates to an underground wireless communication control system. Background Technology

[0002] Underground wireless communication systems are critical infrastructure for safe mining operations, undertaking core tasks such as equipment monitoring, personnel positioning, and emergency command. However, traditional underground wireless communication systems often employ a hybrid wired and wireless networking approach, which suffers from a series of technical drawbacks:

[0003] Existing systems typically rely on a single password for authentication, with vague hierarchical access permissions, making it difficult to effectively prevent unauthorized operations.

[0004] Conventional systems only issue alarms after a physical connection is lost, failing to anticipate operational intentions and making effective intervention before erroneous operations occur. Existing technologies lack intelligent judgment capabilities based on the linkage between equipment status and operational behavior, making it difficult to meet the high stability requirements of communication systems for safe mining production.

[0005] When communication is interrupted, traditional systems typically require manual on-site troubleshooting, and the recovery process is time-consuming on average, severely impacting the continuity of mine production activities. Existing systems mainly rely on periodic manual inspections, making it difficult to detect potential problems such as excessive dust accumulation and aging components in a timely manner, often only allowing for reactive maintenance after a failure occurs. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a downhole wireless communication control system. This system aims to solve the problems of insufficient operational safety control, delayed prediction of erroneous operation intentions, low efficiency in communication interruption recovery, and passive response in equipment maintenance of existing downhole wireless communication control systems.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0008] A downhole wireless communication control system, comprising:

[0009] Access control module: used to perform multi-factor authentication of operators and record operation requests and results;

[0010] Intelligent recognition module: Used to monitor the power supply and network cable interface parameters of communication equipment through intelligent sensors, and to determine the operation intention based on machine learning algorithms;

[0011] Communication notification module: When a misoperation is determined, it generates a prompt message including operator information, equipment location, time, scope of impact, and recovery instructions, determines the emergency level and notification recipients based on the severity, and sends the prompt message to relevant personnel through SMS gateway, voice call, and in-system message push channels;

[0012] Emergency Recovery Assistance Module: This module provides detailed guidance on recovery operations in the prompt messages, including steps, precautions, and tools. It also guides on-site personnel to restore communication through remote assistance. Simultaneously, it adjusts wireless communication network parameters during the recovery process, switching some services to other normal links or frequency bands to ensure uninterrupted critical communication services. The module dynamically adjusts the protection strategy as the recovery progresses.

[0013] Core Control Center: Used to receive and analyze data transmitted by smart sensors, coordinate the operation of various modules, and perform functions such as communication resource scheduling, signal routing planning, data processing, and storage.

[0014] The multi-factor authentication of the access control module includes fingerprint, facial recognition and password combination verification. When an operator requests a critical operation, he or she must send an authorization request to his or her supervisor, and the operation can only be executed after approval.

[0015] The intelligent identification module monitors parameters including power supply voltage, current, and network cable connection status, and integrates operator identity, historical records, and equipment status information to construct an operation intention recognition model.

[0016] The machine learning algorithm of the intelligent recognition module can continuously optimize the operation intention recognition model to improve the recognition accuracy.

[0017] The communication notification module configures information sending channels and notification strategies based on actual communication conditions and personnel contact information.

[0018] During the communication restoration process, the emergency recovery assistance module dynamically adjusts the temporary communication protection strategy based on the network conditions.

[0019] It also includes an equipment maintenance management module, used for:

[0020] The dust accumulation monitoring submodule and the component aging monitoring submodule are used to monitor the dust accumulation on the equipment surface and key heat dissipation parts in real time, as well as the condition of aging components of explosion-proof equipment.

[0021] The regular maintenance plan submodule and the component replacement early warning submodule are used to formulate maintenance plans and send reminder notifications, as well as send early warning information for component replacement in advance.

[0022] Provide maintenance personnel with operational instructions for equipment cleaning and component replacement;

[0023] Maintenance records are automatically generated, and after confirmation by maintenance personnel, historical maintenance records can be queried and analyzed.

[0024] The equipment maintenance management module automatically identifies changes in equipment operating status through intelligent sensors and generates maintenance records based on equipment status monitoring data, eliminating the need for manual data entry.

[0025] It also includes a security monitoring and early warning module, used for:

[0026] Temperature sensors are installed in key parts of the equipment through a temperature monitoring submodule to monitor the equipment's operating temperature in real time and issue an alarm when abnormalities occur.

[0027] The explosion-proof performance monitoring submodule continuously monitors the explosion-proof parameters of the explosion-proof equipment and sends early warning information when the parameters are abnormal.

[0028] The security risk assessment submodule regularly assesses system security risks and generates security risk reports.

[0029] It also includes a system integration and linkage module, used for:

[0030] Integrate all functional modules to ensure information exchange and functional synergy;

[0031] When equipment malfunctions or poses safety risks, automatic linkage control between modules can be achieved.

[0032] The core control center is located in the ground control center and is equipped with a high-performance server cluster and communication management system software.

[0033] Compared with the prior art, the beneficial effects of this invention are:

[0034] Multi-factor authentication strictly limits operation permissions to prevent unauthorized operations, accurately records the operation process and results, facilitates traceability of responsibility, and ensures the security of the communication system. The intelligent recognition module monitors key parameters of communication equipment, integrates multiple information to build an intent recognition model, optimizes the model through machine learning, and promptly detects and intervenes in erroneous operations, improving system stability.

[0035] After identifying a misoperation, the communication notification module quickly generates a detailed prompt message, determines the urgency level and notification recipients based on the severity, and sends it promptly through multiple channels, shortening response time and improving recovery timeliness. The emergency recovery assistance module provides recovery operation guidance, remotely assists in guiding on-site recovery, dynamically adjusts network parameters, and switches service links or frequency bands to ensure uninterrupted critical communication services and improve emergency recovery efficiency.

[0036] The equipment maintenance management module monitors equipment dust accumulation and component aging in real time, proactively develops maintenance plans and provides early warnings, offers operational guidance, and automatically generates maintenance records, achieving scientific and automated management and reducing failure rates. The safety monitoring and early warning module monitors the temperature and explosion-proof parameters of critical equipment components in real time, promptly issuing alarms and warnings when abnormalities occur, regularly assessing safety risks and generating reports, thereby improving system safety performance.

[0037] The system integration and linkage module integrates various functional modules to ensure information interaction and functional collaboration. When equipment malfunctions or poses safety risks, it enables automatic linkage control, improving operational efficiency and response capabilities.

[0038] The core control center is located on the ground and equipped with a high-performance server cluster and software, possessing powerful communication resource scheduling, signal routing planning, data processing and storage capabilities, thereby improving system performance and reliability. Attached Figure Description

[0039] Figure 1 This is a schematic diagram of the modular structure of the system of the present invention. Detailed Implementation

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] like Figure 1 As shown, this downhole wireless communication control system mainly consists of an access control module, an intelligent identification module, a communication notification module, an emergency recovery assistance module, an equipment maintenance and management module, a safety monitoring and early warning module, and a system integration and linkage module. Under the coordination of the core control center, each module achieves effective control over downhole wireless communication.

[0042] Access Control Module: During system initialization, all operator information and access levels are entered into the access control module. Dedicated personnel are regularly assigned to update and maintain authentication data, including but not limited to updating operator fingerprints, facial recognition data, and passwords, to ensure the accuracy and reliability of identity authentication.

[0043] When an operator requests a critical operation such as disconnecting the power or network cable, the access control module first requires the operator to perform multi-factor authentication using fingerprint, facial recognition, and password. After successful authentication, the module will again require the operator to confirm the operation and enter the reason for the operation. Simultaneously, the module automatically sends an authorization request, including details of the operation request, to the supervisor via SMS or internal system message. All operation requests and related results are meticulously recorded and stored in the system's database for subsequent retrieval and auditing.

[0044] Intelligent identification module: Through intelligent sensors installed at the power supply and network cable interfaces of communication equipment, parameters such as power supply voltage, current and network cable connection status are monitored in real time.

[0045] The core control center integrates operator identity information (obtained from the access control module), historical operation records, and equipment status information, and uses machine learning algorithms to build an operation intent recognition model. As the system continues to operate, the intelligent recognition module continuously collects new operation data and uses this data to train and optimize the machine learning algorithm, constantly improving recognition accuracy. For example, the model undergoes large-scale optimization training regularly (monthly) to adapt to constantly changing operating environments and personnel behavior patterns.

[0046] Communication Notification Module: When the intelligent identification module determines an operation to be erroneous, the communication notification module immediately generates a notification message based on preset rules, including operator information, equipment location, time, scope of impact, and recovery instructions. The urgency level is determined based on the potential severity of the erroneous operation, categorized as high, medium, and low, with high-risk operations potentially affecting communication across the entire area receiving the highest priority. Simultaneously, the notification recipients are determined based on the urgency level and the responsibilities of relevant personnel; for example, high-risk operations will notify the system administrator, relevant area supervisors, and on-site maintenance personnel.

[0047] Based on actual communication conditions (such as network signal strength and coverage) and personnel contact information (such as mobile phone numbers and system accounts), information sending channels and notification strategies can be flexibly configured. In emergencies, voice calls and SMS gateways are prioritized for notification to ensure timely delivery of information; in general situations, relevant personnel are notified via system push notifications. The system will automatically select the optimal combination of sending channels and send messages to ensure that relevant personnel receive notifications quickly.

[0048] Emergency Recovery Assistance Module: The communication recovery prompts detail the steps for recovery, including but not limited to how to reconnect power or network cables and check device status. It also lists precautions during the process, such as preventing overheating and avoiding short circuits, as well as a list of necessary tools. Through remote assistance features, such as video conferencing guidance and remote desktop control, it guides on-site personnel to restore communication step-by-step.

[0049] During the recovery process, the emergency recovery support module monitors the communication network status in real time and dynamically adjusts wireless communication network parameters based on the actual situation, such as adjusting transmission power and switching frequency bands. For certain services, depending on their importance and urgency, they are switched to other normal links or frequency bands to ensure uninterrupted critical communication services. As the recovery work progresses, the protection strategy is gradually adjusted until communication is fully restored to normal.

[0050] The equipment maintenance management module includes several sub-modules: a dust monitoring sub-module, and a component aging monitoring sub-module. The dust monitoring sub-module uses sensors installed on the equipment surface and key heat dissipation areas to monitor dust accumulation in real time and transmits the data to the equipment maintenance management module. The component aging monitoring sub-module utilizes relevant detection technologies to continuously monitor the condition of aging components in the explosion-proof equipment, such as insulation performance and mechanical strength. The scheduled maintenance plan sub-module generates detailed maintenance plans based on equipment operating time and maintenance cycles, and sends reminders to maintenance personnel before the scheduled maintenance dates. The component replacement early warning sub-module uses component aging monitoring data to predict potential component failure times and sends component replacement early warning information, reminding maintenance personnel to prepare for component replacement in advance. It also provides maintenance personnel with operational guidance for equipment cleaning and component replacement, including cleaning methods, tool usage, and component installation procedures.

[0051] Intelligent sensors automatically identify changes in equipment operating status, such as the start and end times of maintenance operations and the content of maintenance. Combined with equipment status monitoring data and response to maintenance alerts, maintenance records are automatically generated. After completing the maintenance work, maintenance personnel only need to confirm the record to complete the recording process. Confirmed maintenance records can be queried and statistically analyzed to facilitate the analysis and tracing of equipment maintenance history.

[0052] Safety monitoring and early warning module: The temperature monitoring submodule monitors the equipment's operating temperature in real time through temperature sensors installed on critical parts of the equipment. The system has preset temperature thresholds. When the detected equipment temperature rises abnormally and exceeds the threshold, an alarm is immediately issued, alerting maintenance personnel through sound, light, or system messages.

[0053] The explosion-proof performance monitoring submodule continuously monitors various explosion-proof parameters of the equipment, such as the sealing performance of the explosion-proof enclosure and the explosion-proof electrical clearance, to ensure compliance with explosion-proof standards. If any abnormal parameters are detected, an early warning message is immediately sent to remind relevant personnel to take timely measures to avoid potential safety accidents.

[0054] Safety Risk Assessment and Reporting: The safety risk assessment submodule comprehensively considers multiple factors such as equipment operating status, environmental factors, and personnel operations, and conducts regular (e.g., quarterly) assessments of system safety risks, generating a safety risk report. The report includes the source of the risk, the risk level, the potential scope of impact, and corresponding countermeasure recommendations, providing a basis for decision-making in system safety management.

[0055] The system integration and linkage module organically integrates various functional modules such as the access control module, intelligent identification module, communication notification module, emergency recovery assistance module, equipment maintenance management module, and security monitoring and early warning module. Through a unified data interface and communication protocol, it ensures smooth information exchange between the modules.

[0056] When equipment exhibits potential malfunctions or safety risks, the system integration and linkage module can automatically trigger coordinated control between relevant modules. For example, when the safety monitoring and early warning module detects that the equipment temperature is too high, the linkage communication notification module immediately sends an alarm message to relevant personnel. At the same time, the linkage emergency recovery auxiliary module adjusts communication parameters to reduce equipment load and prevent the fault from escalating further.

[0057] The core control center is located at the surface core control center and is equipped with a high-performance server cluster to meet the needs of large-scale data processing and storage. The server cluster runs communication management system software, which has core functions such as downhole communication resource scheduling, signal routing planning, data processing and storage. The core control center provides unified management and coordination for the entire downhole wireless communication control system, enabling efficient operation and collaborative work of each module.

[0058] Through the specific implementation methods of the above modules, this downhole wireless communication control system can effectively ensure the safe, stable and efficient operation of downhole communication, and improve the safety and production efficiency of downhole operations.

[0059] The above description only illustrates preferred embodiments of the present invention, but the present invention is not limited to the above embodiments.
