Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a communication support method and apparatus, electronic equipment and storage medium for open-pit mines. Background Technology

[0002] Open-pit mine communication networks are critical infrastructure for intelligent mining, widely used in core scenarios such as unmanned mining truck scheduling, remote blasting control, and high-definition video surveillance. However, with increasing mining depth and higher levels of equipment automation, traditional 4G / LTE networks can no longer meet the stringent requirements for high availability. The current technology system has significant shortcomings: it primarily relies on a single-link wired network and localized wireless coverage; the physical layer uses a single optical cable route; the network layer largely uses the traditional STP protocol (convergence time exceeding 1 second); the equipment layer lacks redundancy design; and an overall cross-layer collaborative reliability assurance mechanism has not been formed. The existing architecture uses a single-route tree topology and non-redundant equipment configuration, resulting in a single point of failure risk at the physical layer. Furthermore, video surveillance is prone to congestion during peak traffic; and the mismatch between the link layer bit error rate and the network layer probe interval further exacerbates fault detection and recovery latency, ultimately affecting mine production continuity and operational safety.

[0010] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of this disclosure, nor is it intended to limit the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

Detailed Implementation

[0012] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0013] The following description, with reference to the accompanying drawings, outlines a communication assurance method and apparatus, electronic device, and storage medium for open-pit mines according to embodiments of the present disclosure.

[0014] Figure 1 This is a flowchart illustrating a communication assurance method for an open-pit mine, as provided in an embodiment of this disclosure.

[0015] like Figure 1 As shown, the method includes the following steps: Step 101: Construct a physical dual-router Ethernet ring network architecture, wherein the physical dual-router includes a primary route and a backup route, and the primary route and the backup route maintain a preset distance.

[0016] In the embodiments of this disclosure, to meet the reliability requirements of open-pit mine communication networks, an Ethernet ring network architecture with physical dual routing is first constructed. This architecture includes a primary route and a backup route that cooperate with each other, maintaining a preset spatial distance between them. This ensures that the backup route can independently perform communication transmission when the primary route fails, avoiding the risk of simultaneous damage due to routes being too close together, thus providing basic link-level redundancy for open-pit mine communication. As one implementation method, the preset distance can be determined based on the mining area, geological conditions, and equipment deployment density of the open-pit mine to balance link transmission efficiency and fault isolation effectiveness.

[0017] This technology can effectively solve the problem of single-point failures that are prone to occur when using a single optical cable route in the existing open-pit mine communication network. Through the physical redundancy design of the primary and backup routes and the preset spacing in space, the impact of failures such as link breakage on communication is significantly reduced, thereby improving the overall reliability and risk resistance of the open-pit mine communication link.

[0018] Step 102: Configure a single-board level redundancy protection mechanism for key devices in the Ethernet ring network architecture. The key devices include a baseband processing unit and a core network server. The baseband processing unit adopts a hardware redundancy design with dual main control boards, dual power supply boards, and dual baseband processing boards, and realizes data synchronization between boards through a high-speed bus. The core network server adopts a dual-machine hot standby architecture and maintains state synchronization through a heartbeat detection mechanism.

[0019] In the embodiments of this disclosure, based on the existing physical dual-route Ethernet ring network architecture, a single-board-level redundancy protection mechanism is configured for key equipment to ensure stable communication. This key equipment includes at least a baseband processing unit and a core network server, further improving the overall network reliability at the device level. Specifically, the baseband processing unit employs a multi-module hardware redundancy design, with multiple functional boards respectively undertaking main control, power supply, and baseband processing functions, preventing equipment downtime due to a single board failure. Simultaneously, a high-speed data transmission link enables real-time data synchronization between boards, ensuring consistent equipment operating status. The core network server adopts a primary / backup dual-machine collaborative architecture, with a continuous status detection mechanism monitoring the operating status of the primary and backup machines in real time, ensuring synchronization of functions and data between the primary and backup machines so that the backup machine can quickly take over services in case of primary equipment failure. As one implementation method, the high-speed data transmission link can be a high-speed bus type such as PCIe bus, and the detection interval of the status detection mechanism can be flexibly set according to the latency requirements of the open-pit mine business.

[0020] This technology can solve the problems of high single-point failure risk and long fault recovery time caused by the lack of redundancy design in key equipment in existing technologies. By using hardware redundancy in the baseband processing unit and dual-machine hot standby design of the core network server, combined with data synchronization and status detection mechanisms, it can effectively avoid the impact of single module or single machine failure on communication services, significantly improve the stability and fault response capability of key equipment operation, and ensure the continuous operation of communication services in open-pit mines.

[0021] Step 103: Based on the preset protection protocol and the software-defined network controller, perform fault detection and path reconstruction, wherein the software-defined network controller dynamically adjusts the traffic path when a link layer anomaly is detected according to the preset topology database.

[0022] In the embodiments of this disclosure, based on a physical dual-route Ethernet ring network architecture and single-board-level redundancy protection for key equipment, fault detection and path reconstruction operations are performed collaboratively with a software-defined network (SDN) controller, relying on a preset protection protocol. The preset protection protocol provides standardized specifications for fault identification, judgment, and path adjustment processes, ensuring the orderly execution of detection and reconstruction actions. The SDN controller pre-stores a topology database containing information such as network nodes and link connections. When an anomaly is detected at the link layer (such as link interruption or transmission quality degradation), it can quickly call the network structure information in the preset topology database, analyze and determine available alternative paths, and dynamically adjust the transmission paths of service traffic to avoid communication interruptions due to a single link anomaly. As one implementation, the preset protection protocol can be a ring network protection protocol adapted to the characteristics of the Ethernet ring network, and the preset topology database can be updated periodically according to changes in the network topology to ensure the accuracy of link information.

[0023] This technology can solve the problems of existing technologies where fault detection and path recovery rely on traditional protocols, are inefficient, and cannot dynamically adjust paths. By combining a preset protection protocol with a software-defined network controller, and with the help of a pre-built topology database, it can quickly identify link-layer anomalies and dynamically reconstruct traffic paths, significantly shortening fault response and recovery latency and ensuring continuous transmission of open-pit mine communication services when links are abnormal.

[0024] Step 104: Perform dynamic migration operation of base stations. Trigger the migration process based on environmental monitoring data, and realize the deployment of base station configuration and service switching through network function virtualization technology.

[0025] In the embodiments of this disclosure, to adapt to the dynamic environmental changes during open-pit mining and their impact on communication coverage, a dynamic base station migration operation is performed. Environmental monitoring data serves as the trigger for the migration process, ensuring that the migration timing precisely matches the actual coverage needs of the mine and avoiding communication blind spots caused by environmental changes. Simultaneously, network function virtualization (NFV) technology is used to virtualize the parameters and functional modules related to the base station configuration, enabling rapid deployment of base station configurations and smooth switching of service transmissions. This eliminates the need for inefficient operations such as traditional manual wiring, reducing the impact of the migration process on communication services. As one implementation method, the environmental monitoring data may include data such as the location of the mining pit and the signal coverage strength of the base station. When monitoring data shows that the existing base station coverage cannot meet the requirements, migration is triggered. NFV technology can accelerate configuration and deployment by encapsulating the base station configuration as a virtual image.

[0026] This technology can solve the problems of existing technologies where base station migration relies on manual wiring, is time-consuming, and cannot adapt to the dynamic coverage needs of mining pit advancement. By accurately triggering migration through environmental monitoring data and simplifying configuration switching through network function virtualization technology, it significantly shortens the base station migration cycle, ensures that mine communication coverage is dynamically adjusted according to the mining environment, and guarantees continuous coverage and stable transmission of open-pit mine communication services.

[0027] The communication assurance method for open-pit mines disclosed herein constructs a physical dual-route Ethernet ring network architecture with primary and backup routes and maintaining a preset spacing. In this architecture, a single-board-level redundancy protection mechanism is configured for the baseband processing unit (which adopts a hardware redundancy design with dual main control boards, dual power supply boards, and dual baseband processing boards, and realizes board data synchronization through a high-speed bus) and the core network server (which adopts a dual-machine hot standby architecture and maintains state synchronization through a heartbeat detection mechanism). Furthermore, based on a preset protection protocol and a software-defined network controller (which dynamically adjusts traffic paths when there are link layer anomalies by relying on a preset topology database), fault detection and path reconstruction are performed. At the same time, dynamic migration operations of base stations are performed, which are triggered by environmental monitoring data and realize the configuration, deployment, and service switching of base stations through network function virtualization technology. Therefore, it can solve the problems of high single-point failure risk, long fault recovery time, and difficulty in adapting to the dynamic coverage requirements of mining pit advancement caused by the use of a single-route topology, lack of single-board-level redundancy of key equipment, low efficiency of fault detection and path recovery, and reliance on manual migration of base stations in the prior art. This achieves the technical effect of improving the reliability of open-pit mine communication networks, shortening fault recovery latency, and meeting the dynamic coverage and service continuity requirements of mines.

[0028] Furthermore, in one possible implementation of this embodiment, the core network device in the Ethernet ring network architecture adopts a dual-machine hot standby architecture and maintains state synchronization through a heartbeat detection mechanism.

[0029] Specifically, in this embodiment, for the core network equipment in the Ethernet ring network architecture, a dual-machine hot standby architecture is adopted, with a primary core network equipment and a backup core network equipment deployed in parallel. Both are consistent in hardware configuration and software functionality, and jointly access the Ethernet ring network transmission link to achieve data interaction. To maintain state synchronization between the primary and backup devices, a real-time communication link is established between them through a heartbeat detection mechanism. This mechanism sends heartbeat data packets containing device operating status (such as CPU utilization and memory usage), service data status (such as current session connection count and data transmission progress), and configuration parameters to the backup device at preset time intervals (e.g., 50ms-200ms). The backup device receives and parses the heartbeat data packets in real time. If it fails to receive a valid heartbeat data packet multiple times consecutively (e.g., 3 times), or if the parsing reveals an operational anomaly in the primary device (e.g., core module failure or data transmission error), it is determined that the primary device is not functioning properly. Meanwhile, during normal operation, the primary device will synchronize its core configuration parameters (such as network protocol parameters and service permission configuration), user session data, and service flow status to the backup device in real time, ensuring that the information stored on the backup device is completely consistent with that of the primary device, so that it can directly take over the service during the switchover.

[0030] This specific implementation can effectively avoid the problem of communication service interruption in open-pit mines caused by single point of failure of core network equipment. It provides hardware-level redundancy support through dual-machine hot standby architecture, and realizes real-time monitoring and data synchronization of the status of primary and backup equipment by combining heartbeat detection mechanism. It can not only quickly identify the anomaly of the primary equipment, but also ensure that the backup equipment can seamlessly take over the service based on the synchronized data, significantly shortening the service recovery time after the failure of core network equipment, and further improving the operational reliability of Ethernet ring network architecture at the core node level.

[0031] Furthermore, in one possible implementation of this embodiment, the fault detection of the Ethernet ring network architecture includes: the link layer adopts a bit error rate monitoring algorithm, and triggers path switching conditions when the bit error rate is greater than the bit error rate threshold for a continuous preset detection period; the software-defined network controller, based on the topology database stored in the FPGA, uses the shortest path algorithm to prioritize the selection of backup links with optical power not lower than a preset value for traffic reconstruction.

[0032] Specifically, when performing fault detection on an Ethernet ring network architecture, the link layer uses error detection algorithms (such as Cyclic Redundancy Check (CRC) and parity check algorithms) to perform real-time verification of transmitted data frames. The bit error rate of data transmission is calculated every preset detection period (e.g., 100ms), and a bit error threshold (e.g., 10) is set. -6 If the bit error rate (BER) is greater than the threshold for three consecutive detection cycles, and temporary factors such as signal interference at the data transmission end are excluded, a persistent anomaly is determined at the link layer. This triggers a path switching condition and sends an anomaly notification to the Software-Defined Networking (SDN) controller. The SDN controller has a built-in FPGA (Field-Programmable Gate Array) chip. This chip pre-stores a topology database containing the physical connection relationships, link bandwidth, optical power parameters, and node device location information of all links within the Ethernet ring network. The FPGA chip, with its high-speed parallel processing capabilities, can achieve microsecond-level reading of the topology data. After receiving the link anomaly notification, the controller calls a shortest path algorithm (such as Dijkstra's algorithm) to calculate the path for available links in the topology database. During the calculation, it prioritizes selecting backup links with optical power not lower than a preset value (e.g., -15dBm, determined based on the attenuation characteristics of optical cables in open-pit mines) to ensure stable transmission quality. Once the optimal backup link is determined, the controller sends a traffic forwarding command to the relevant node devices within the ring network, dynamically switching the service traffic carried by the original abnormal link to the backup link, thus completing traffic reconstruction.

[0033] By combining error detection algorithms with preset period and threshold judgment logic, continuous anomalies at the link layer can be accurately identified, avoiding false switching caused by momentary interference. At the same time, high-speed data reading is achieved by using FPGA storage topology database. With the shortest path algorithm and optical power screening conditions, the optimal backup link can be quickly determined, and the transmission stability of the reconstructed link can be guaranteed. This effectively shortens the total latency of fault detection and path reconstruction, and further ensures the continuous transmission of high real-time services in open-pit mines (such as unmanned mining truck scheduling).

[0034] Furthermore, in one possible implementation of this embodiment, it further includes: performing traffic scheduling through the software-defined network controller and dynamically allocating bandwidth resources according to real-time service type and priority.

[0035] Specifically, in this embodiment, the Software-Defined Networking (SDN) controller first performs real-time parsing of service data frames transmitted within the Ethernet ring network using Deep Packet Inspection (DPI) technology. This extracts service identification fields (such as port number, protocol type, and application signature) from the data frames, thereby accurately identifying the real-time service types in the current network, such as unmanned mining truck scheduling, remote blasting control, and high-definition video surveillance. Subsequently, based on the importance and real-time requirements of the open-pit mine services, the controller presets service priority allocation rules. Services sensitive to latency and affecting operational safety (such as unmanned mining truck scheduling and remote blasting control) are classified as high priority, while services with higher latency tolerance (such as high-definition video surveillance in non-critical areas) are classified as medium- and low priority. Corresponding bandwidth guarantee levels are then allocated to services of different priorities. In the bandwidth resource allocation phase, the SDN controller collects data such as the total bandwidth utilization of the ring network and the current bandwidth usage of each service in real time to build a dynamic bandwidth resource pool. When an increase in high-priority service traffic is detected (such as an increase in the number of unmanned mining trucks leading to an increase in scheduling command transmission volume), the controller automatically adjusts the bandwidth allocation ratio, reserving no less than 30% of the total ring network bandwidth for high-priority services to ensure their transmission needs are met first, and avoiding excessive bandwidth consumption by medium and low-priority services. If medium and low-priority services experience traffic peaks (such as a sudden increase in data volume due to video surveillance screen switching), the controller dynamically allocates the remaining idle bandwidth to medium and low-priority services without affecting the bandwidth of high-priority services. At the same time, it uses traffic shaping technology to limit the maximum bandwidth usage of a single medium and low-priority service to prevent it from excessively consuming resources.

[0036] By using an SDN controller to accurately identify service types and dynamically schedule priorities, it can ensure that core services with high security and real-time requirements in open-pit mines (such as unmanned driving and remote blasting) receive stable bandwidth support, avoiding increased transmission latency or data loss due to bandwidth contention. It can also flexibly utilize idle bandwidth to meet the transmission needs of medium and low priority services, significantly improving the utilization rate of ring network bandwidth resources and adapting to the differentiated communication needs of different services in open-pit mines.

[0037] Furthermore, in one possible implementation of this embodiment, the execution of traffic scheduling through the software-defined network controller includes: for bursty video surveillance services, the controller dynamically allocates a bandwidth buffer pool according to a preset proportion of the total bandwidth of the ring network; when using the weighted fair queue algorithm, the weight coefficient for autonomous driving services is allocated to a preset multiple of the default value.

[0038] Specifically, when performing traffic scheduling through a software-defined network controller, for sudden surges in video surveillance traffic, the controller pre-sets a predetermined percentage (e.g., 20%-30%) of the total ring network bandwidth as a dedicated bandwidth buffer pool. This buffer pool is independent of the bandwidth allocation areas for other services. When a sudden increase in video surveillance traffic is detected (e.g., due to increased switching frequency of surveillance camera footage caused by blasting operations in a mining area, with peak traffic reaching 160Mbps), the controller calls upon the buffer pool resources in real time to prioritize meeting its sudden bandwidth demand. If the sudden traffic exceeds the buffer pool capacity, the controller temporarily allocates some resources from idle bandwidth to supplement the buffer pool without affecting high-priority services. At the same time, it limits the transmission rate of non-critical video streams through a traffic marking mechanism to prevent the buffer pool from excessively consuming total bandwidth. For the application of the weighted fair queue algorithm, the controller sets a basic weight coefficient for different service types (the default value is set to 1). The weight coefficient assigned to the autonomous driving service is a preset multiple of the default value (e.g., 2-3 times). During the queue scheduling process, the algorithm calculates the queue scheduling priority of each service based on the weight coefficient. The autonomous driving service, due to its higher weight, gets more frequent scheduling opportunities, and its data frame waiting time in the queue is shortened. Even when the network load is high (such as when multiple services are transmitted at the same time), it can still occupy transmission resources first.

[0039] By configuring a dynamic bandwidth buffer pool for sudden surges in video surveillance services, network congestion caused by traffic peaks can be effectively addressed, ensuring continuous transmission of monitoring data. Meanwhile, allocating weighted fair queue scheduling with a higher weight coefficient to unmanned driving services can significantly reduce transmission latency, ensure the real-time nature of mining card scheduling instructions, and further improve the communication quality and rationality of network resource allocation for critical open-pit mine services.

[0040] Furthermore, in one possible implementation of this embodiment, the migration process triggered by environmental monitoring data and the deployment of base station configuration and service switching through network function virtualization technology include: predicting network coverage blind spots based on the pit-moving advancement model updated by UAV mapping; when the signal strength index is continuously lower than the migration threshold, performing network optimization migration on the Ethernet ring network architecture; and encapsulating the base station configuration parameters into a virtual image through network function virtualization technology, with service traffic carried through the backup route during the migration process.

[0041] Specifically, when triggering the base station migration process based on environmental monitoring data and implementing configuration deployment and service switching through network function virtualization technology, the open-pit mine area is first mapped in 3D using drones at a preset cycle (e.g., once a day). Data such as the advance distance of the pit boundary and changes in terrain elevation are collected and input into the pit advance model for real-time updates. This model, combined with the mine's mining plan (e.g., a daily advance of 300m), simulates and predicts potential network coverage blind spots (e.g., newly excavated areas at the bottom of the pit, areas obstructed by slopes) that may occur within the next 1-2 mining cycles. Simultaneously, signal detection nodes are deployed in key operational areas of the mine to collect signal strength indicators such as Received Signal Strength Indication (RSSI) and Reference Received Power (RSRP) of the base stations in real time. When the signal strength indicators of a certain area are lower than the migration threshold (e.g., RSSI ≤ -90dBm, RSRP ≤ -110dBm) for three consecutive detection cycles (each cycle being 10 minutes), it is determined that there is a coverage risk in that area, triggering the base station network optimization migration process in the Ethernet ring network architecture. During the migration implementation phase, network function virtualization (NFV) technology is used to encapsulate the core configuration information of the base station to be migrated, such as radio frequency parameters (e.g., frequency band, transmit power), network protocol configuration (e.g., IP address, routing rules), and service permission parameters, into a standardized virtual image file and store it in the image management module of the software-defined network controller. During the migration, the controller sends a virtual image loading command to the general hardware device at the target deployment location to complete the rapid deployment of the base station configuration. At the same time, it sends a traffic forwarding command to temporarily switch the service traffic carried by the original base station to the backup route in the physical dual routing until the new base station starts up and reaches a stable coverage state. Then, the traffic is switched back to the new base station to achieve seamless service switching.

[0042] By combining UAV mapping with mining pit advancement models, coverage blind spots can be predicted in advance, avoiding communication interruptions caused by mining pit advancement; migration is triggered based on signal strength thresholds to ensure that the migration timing accurately matches actual coverage needs; virtual image encapsulation using NFV technology significantly shortens base station configuration and deployment time, and with backup routes carrying service traffic during the migration process, the impact of base station migration on open-pit mine operation communication can be completely avoided, further improving the adaptability of the communication network to the dynamic mining environment.

[0043] It should be noted that the embodiments of this disclosure may include multiple steps. For ease of description, these steps are numbered, but these numbers are not a limitation on the execution time slots or execution order between the steps; these steps can be implemented in any order, and the embodiments of this disclosure do not limit this.
