Description

Technical Field

[0001] This invention belongs to the field of remote intelligent monitoring technology for natural gas stations, specifically involving a high-availability network networking method for natural gas stations based on the open-source HarmonyOS soft bus. Background Technology

[0002] As a critical infrastructure for ensuring a stable supply of natural gas, the stability, reliability, and efficiency of the automated control systems at natural gas stations play a vital role in the safe transportation and stable supply of natural gas. However, traditional natural gas station network technologies have many limitations and cannot meet the high network performance requirements of modern natural gas stations.

[0003] Traditional natural gas station network topologies primarily rely on wired connections, tightly linking field equipment to the control system. While this method initially met basic communication needs, its drawbacks have become increasingly apparent with the increasing number of devices, significantly enhanced system complexity, and ever-growing demands for real-time, integrity, and reliability of data transmission. First, traditional network topologies depend on hard-wired connections between devices and controllers. This lack of redundancy means that a failure at any connection point can paralyze the entire network, severely impacting the normal operation of the natural gas station. Second, traditional networks only support wired-to-wired redundancy, offering extremely low flexibility and making it difficult to adapt to complex field environments. Deployment is also more difficult and costly. Furthermore, traditional networks rely heavily on retransmission mechanisms to ensure data integrity. This approach is not only inefficient but also wastes resources, leading to time delays and impacting real-time data transmission. Finally, the relatively rigid structure of traditional networks, lacking flexible system mechanisms, makes system development and deployment difficult, as well as maintenance and upgrades challenging.

[0004] With the rapid development of information technology, new technologies such as cloud computing, big data, the Internet of Things, mobile communication, and artificial intelligence are constantly emerging and being applied to various fields. Meanwhile, the open-source HarmonyOS ecosystem is also continuously improving. Applying the independently controllable open-source HarmonyOS operating system to the industrial field and building an independently controllable industrial control ecosystem has become an important technological development trend in the current industrial automation field. The open-source HarmonyOS operating system has unique advantages such as distributed soft bus, device virtualization, distributed event notification, and intelligent task scheduling. These characteristics provide new ideas and methods for solving the problems existing in traditional natural gas station network networking technologies, and are expected to bring revolutionary changes to natural gas station network networking. Summary of the Invention

[0005] To address the aforementioned technical issues, this invention provides a high-availability network topology method for natural gas stations based on the open-source HarmonyOS soft bus. By modifying field equipment to HarmonyOS and utilizing soft bus technology to achieve dynamic networking, multi-path transmission, and redundancy verification optimization, this method provides gas stations with a network connection that is low in development difficulty, low in deployment cost, highly flexible, highly efficient, and highly available.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-availability network topology method for natural gas stations based on the open-source HarmonyOS soft bus includes the following:

[0008] 1. Communication data structure integration and interface specification design for the HarmonyOS platform: This work first combines the distributed soft bus characteristics and device virtualization functions of the open-source HarmonyOS system to form communication data specifications and interface definitions related to the physical model of natural gas process equipment. HarmonyOS DDM service is used to provide distributed data management support for this data structure, transforming the key parameters (pressure, temperature, flow), operating status (valve opening and closing, fault signals), and control commands (parameter adjustment, start and stop operations) of gas equipment into a standardized data model. The data objects of this system support consistent data presentation among multiple devices, realizing real-time synchronization and status unification of logical data across physical devices.

[0009] This design encapsulates standardized data objects using HarmonyOS's Atomic Service interface. HarmonyOS adopts an atomic service architecture, encapsulating functions into independently distributable lightweight modules. It integrates gas equipment functions and data using atomic services, ensuring compatibility with different gas terminals. Through interface standardization, it meets the requirements of plug-and-play devices and zero-latency data interaction in HarmonyOS. It breaks through the indirect communication path achieved by traditional IoT platforms through message queues or gateway protocol translation. By adopting HarmonyOS's distributed device virtualization solution, it achieves direct communication between the application layer and the logical nodes formed by device virtualization, reducing the complexity of system integration and enhancing real-time interaction capabilities.

[0010] 2. Flexible networking based on HarmonyOS multi-link collaboration and intelligent routing technology: Through the open-source HarmonyOS soft bus, a multi-link collaboration and intelligent routing scheme enables intelligent networking and continuous stable operation of gas equipment in complex network environments. Most equipment within gas stations adopts a hybrid communication architecture, such as Wi-Fi wireless network, standard Ethernet, power line PLC communication, and NB-IoT narrowband technology. The underlying architecture of HarmonyOS can collect multi-dimensional network data from physical links in real time, covering signal quality (RSSI), bandwidth capacity, and transmission latency. Employing HarmonyOS's intelligent QoS awareness system, the system can perceive in real time the specific QoS requirements of running applications (including data acquisition, remote control, etc.) for data transmission, such as fast response, high transmission rate, or strong fault tolerance.

[0011] Based on current network status data and service QoS requirements, HarmonyOS supports dynamically selecting the best-performing physical links for data transmission. When necessary, it uses link aggregation (using a multi-path TCP approach) to combine multiple links, thereby enhancing the overall performance and reliability of the transmission process. This technology is compatible with both device-to-device (D2D) direct connection and HarmonyOS edge gateway proxy connection. Compared with existing solutions that use static single links or conventional backup switching, this real-time responsive link management architecture can effectively match the ever-changing network operating environment of the gas industry and significantly improve the service quality and availability of critical business communications.

[0012] 3. Intelligent data transmission method using HarmonyOS distributed event and task scheduling: To match the special requirements of natural gas transmission and distribution systems for data immediacy and integrity, open-source HarmonyOS is used as the foundation, integrating distributed event notification and intelligent scheduling modules, and launching functional modules such as "dynamic data triggering reporting" and "retransmission after link repair".

[0013] ① Regarding "reporting data whenever it changes": HarmonyOS's distributed event management function is adopted. If the main parameters of the gas equipment (involving pressure exceeding the standard, state switching) cross the preset threshold, the terminal device can dynamically transmit the alarm event to the HarmonyOS message hub. Related devices and upper-layer applications can capture notifications and data in real time through the event subscription mechanism. This method avoids the inherent response lag and bandwidth waste problems of the polling mode, and is also better than the practice of reporting at a fixed frequency, which greatly optimizes the real-time acquisition of key data.

[0014] ② Regarding “data retransmission after communication interruption”: If a network problem causes a communication connection interruption, the underlying features of HarmonyOS Distributed File Management (DFS) and a dedicated distributed database (such as GaussDB for IoT) are used to complete local data caching, transmission continuation, and network reconnection synchronization. After the communication connection is re-established, the system adopts HarmonyOS’s intelligent resource allocation scheme, which integrates key elements such as network instantaneous throughput, device power supply capacity, and data timeliness, and dynamically adjusts the timing, transmission speed, and packet size of data retransmission. This optimizes the process to gradually make up for the data loss caused by the communication interruption, ensuring complete data preservation and preventing high-density data retransmission at the moment the network recovers from becoming a transmission bottleneck.

[0015] 4. Deep integration scheme of dynamic adaptive network topology based on HarmonyOS microkernel and soft bus: This invention organically integrates the open-source HarmonyOS microkernel system with distributed soft bus technology to build a network topology framework that can be autonomously adjusted for gas stations.

[0016] The HarmonyOS microkernel creates an isolated, predictable, and deterministic system environment for the execution of network protocol stacks and core communication tasks (including real-time control command transmission). This design ensures that core communication services and non-real-time tasks do not interfere with each other, enhancing the reliability and real-time processing capabilities of the communication system.

[0017] As the core network architecture, the HarmonyOS distributed soft bus acts as the nervous system. Its operation relies on real-time capability interaction between devices (such as the service modules, computing power, and storage capacity carried by the devices) combined with service discovery feedback to adapt to device connection modes and data transmission trajectories in real time. If a certain aggregation node exceeds the load threshold or stops responding, the data flow is automatically switched to a backup node with a lower load through the soft bus. This architecture supports dynamic load distribution and multi-path data transmission, enabling the gas network to respond in real time to issues such as device entry and exit, sudden failures, and unstable link quality.

[0018] The network topology dynamic adaptive control achieved by HarmonyOS underlying technology effectively improves the flexibility, scalability and anti-interference capability of gas communication networks compared to the rigid topology structure or topology change mode uniformly controlled by a central node used in traditional industrial networks.

[0019] The advantages of this invention compared to the prior art are:

[0020] (1) Achieved a higher level of system compatibility and collaboration: Based on the standard data architecture and interface specifications built by the HarmonyOS DDM framework and atomic services, the plug-and-play and barrier-free data interoperability of various gas equipment in the HarmonyOS environment is achieved, which greatly reduces the configuration complexity and implementation cost of accessing diversified equipment.

[0021] (2) Achieved a dual improvement in communication link flexibility and stable transmission: By adopting HarmonyOS's multi-link collaboration and dynamic routing mechanism, relying on real-time network status feedback and QoS strategy, the system intelligently matches the optimal transmission route, adapts to the real-time fluctuations of gas station network conditions, and achieves reliable and high-quality data transmission.

[0022] (3) Enhanced timeliness and integrity of data synchronization: Using the HarmonyOS distributed event model, the data status changes are quickly synchronized. The distributed storage system and intelligent load balancing are used to complete the data retransmission after communication interruption, which not only meets the real-time data return requirements, but also ensures the traceability of historical data.

[0023] (4) Improved real-time adaptability and system robustness of topology management: By organically combining the precise scheduling capability of HarmonyOS microkernel with the real-time topology adaptation characteristics of distributed soft bus, a communication infrastructure that adapts to device dynamics and network fluctuations has been built, giving the gas monitoring system better elasticity, module expansion and fault-tolerant operation quality.

[0024] (5) Effectively tapping the technical potential of open source HarmonyOS: This invention is not just a simple migration of the application layer of HarmonyOS, but combines the core layer characteristics of HarmonyOS to specifically address the prominent contradictions in gas communication, laying the technical foundation for realizing the intelligent upgrade of gas operation and management. Attached Figure Description

[0025] Figure 1 This is an overall block diagram of a high-availability network topology method for natural gas stations based on the open-source HarmonyOS soft bus, according to the present invention. Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] This invention provides a high-availability network topology method for natural gas stations based on the open-source HarmonyOS soft bus. By integrating HarmonyOS with field devices and combining HarmonyOS soft bus technology with multi-path transmission optimization mechanisms, it replaces traditional networking methods to achieve dynamic networking between devices, cross-media communication, and efficient data transmission. The overall system block diagram of this invention is as follows: Figure 1 As shown, the specific implementation method is as follows:

[0028] Step 1: Unified communication data structure and interface standard based on the physical model of natural gas process equipment;

[0029] (1) HarmonyOS-based transformation of equipment layer and design of communication data structure

[0030] First, the equipment layer is upgraded to be HarmonyOS-enabled. Existing equipment in the natural gas station (such as sensors, controllers, data acquisition devices, etc.) is connected to a HarmonyOS adapter running the open-source HarmonyOS operating system, enabling them to interconnect via the HarmonyOS soft bus. The specific implementation is as follows:

[0031] ① Device Control Interface Adaptation: The control interfaces of field devices (such as SPI, I2C, UART, etc.) are standardized and encapsulated through the HarmonyOS adapter to ensure compatibility with the HarmonyOS soft bus. The adapter performs protocol conversion on the device's control signals and encapsulates the device's original interfaces (such as Ethernet, serial port, CAN bus) into soft bus interfaces for unified access to the HarmonyOS network.

[0032] ② Abstraction of the physical layer and data link layer: The adapter abstracts and encapsulates various physical transmission media (such as wired, wireless, serial, Ethernet, etc.) through the soft bus protocol layer, realizing transparent cross-media communication between devices. Devices do not need to care about the differences in the underlying physical layer and uniformly implement communication functions through the soft bus interface.

[0033] ③ Intelligent Device Self-Discovery and Dynamic Registration: Through the distributed device management module of the soft bus, devices are automatically identified and registered upon connection. The adapter broadcasts the device's unique identifier (UID), device type, supported communication protocols, and physical connection method to the network. After receiving the device information, the soft bus management center automatically adds the device to the network, realizing device self-discovery and self-registration.

[0034] (2) Communication data structure integration and interface specification design;

[0035] By leveraging the distributed soft bus features and device virtualization capabilities of the open-source HarmonyOS system, communication data specifications and interface definitions related to the physical model of natural gas process equipment are formulated. The specific implementation is as follows:

[0036] Distributed Data Management (DDM) Service: HarmonyOS DDM service provides distributed data management support for data structures, transforming key parameters (pressure, temperature, flow), operating status (valve opening and closing, fault signals), and control commands (parameter adjustment, start and stop operations) of gas equipment into standardized data models, supporting consistent data presentation among multiple devices, and realizing real-time synchronization and status unification of logical data across physical devices.

[0037] Atomic Service Interface Encapsulation: By encapsulating standardized data objects using HarmonyOS Atomic Service interfaces, functionalities are packaged into lightweight modules that can be independently distributed. Through interface standardization, the system can achieve plug-and-play functionality and zero-latency data interaction with HarmonyOS devices. This breaks through the indirect communication path achieved by traditional IoT platforms through message queues or gateway protocol translation. By adopting HarmonyOS distributed device virtualization, direct communication between the application layer and the logical nodes formed by device virtualization is achieved, reducing the complexity of system integration and enhancing real-time interaction capabilities.

[0038] Step 2: Multi-link collaboration and intelligent routing selection mechanism;

[0039] A multi-link collaboration and intelligent routing scheme implemented through the open-source HarmonyOS soft bus enables intelligent networking and continuous stable operation of gas equipment in complex network environments. The specific implementation is as follows:

[0040] (1) Multi-link collaboration: Most equipment in gas stations adopts a hybrid communication architecture, such as Wi-Fi wireless network, standard Ethernet, power line PLC communication, and NB-IoT narrowband technology. The underlying architecture of the HarmonyOS system can collect multi-dimensional network data of physical links in real time, covering signal quality (RSSI), bandwidth capacity, and transmission delay. Using HarmonyOS's intelligent QoS perception system, the system can perceive in real time the specific QoS requirements of the running application (including data acquisition, remote control, etc.) for data transmission, such as fast response, high transmission rate, or strong fault tolerance.

[0041] (2) Intelligent Routing Selection: Based on current network status data and service QoS requirements, the HarmonyOS system supports dynamically selecting the best-performing physical link for data transmission. When necessary, it uses link aggregation (adopting a multi-path TCP approach) to combine multiple links, enhancing the overall performance and reliability of the transmission process. This technology is compatible with both device-to-device (D2D) direct connection and HarmonyOS edge gateway proxy connection. Compared with existing solutions that use static single links or conventional backup switching, it can effectively match the ever-changing network operating environment of the gas industry and significantly improve the service quality and availability of critical business communications.

[0042] (3) Using HarmonyOS soft bus technology, users do not need to worry about the physical medium of device connection. As long as the devices are in the same network, dynamic networking between devices can be achieved. The specific implementation is as follows:

[0043] ① Dynamic Networking and Adaptive Topology Construction: The soft bus dynamically constructs the network topology using unique device identifiers and real-time network status. After devices are connected, the soft bus allows for self-discovery between devices through automatic registration and broadcasting, automatically enabling node access, exit, and dynamic topology adjustments. Devices do not require manual configuration of network parameters, simplifying the deployment process.

[0044] ② Network Interruption and Self-Recovery Mechanism: In the event of device failure or network interruption, the soft bus automatically re-establishes the connection and synchronizes topology information through a self-recovery mechanism. The soft bus supports automatic re-registration of nodes, ensuring rapid recovery after node failure or network outages.

[0045] (4) This invention utilizes the unified interface layer and protocol abstraction layer provided by HarmonyOS Soft Bus, enabling developers to focus on business logic and complete inter-device networking and communication by calling a unified API, without needing to understand the specific implementation details of the underlying network when developing network applications. The specific implementation is as follows:

[0046] ① Protocol Abstraction and Cross-Platform Communication: The soft bus supports the encapsulation of multiple communication protocols (such as TCP / IP, UDP, Modbus, HTTP, etc.) through a unified interface and protocol abstraction layer. Developers only need to call a unified API to complete the networking and communication between devices. Through the protocol abstraction layer of the soft bus, devices can seamlessly interoperate across platforms and protocols, ensuring data sharing and collaborative operation between different devices.

[0047] ② Unified API interface and simplified development: The soft bus provides a unified API interface layer, which allows developers to quickly develop applications without having to worry about the underlying network architecture and protocol differences, significantly reducing development difficulty and improving system implementation efficiency.

[0048] (5) This invention designs a multipath transmission mechanism that supports any combination of wired-wired, wired-wireless, and wireless-wireless methods. In environments with limited bandwidth, it achieves balanced channel load and improved bandwidth utilization by splitting data on the transmitting side, transmitting through different channels, and combining data on the receiving side. The specific implementation is as follows:

[0049] ① Multi-path transmission and channel optimization: This invention supports a combination of wired and wireless transmission methods. Through a distributed routing algorithm on a soft bus, the system can dynamically select the optimal transmission path based on real-time network load, bandwidth conditions, and channel interference. During data transmission, the system splits the data stream into multiple sub-streams and transmits them in parallel through different paths to increase overall transmission bandwidth and reliability.

[0050] ② Improved bandwidth utilization: In scenarios with limited bandwidth, the system intelligently allocates transmission traffic by monitoring network status, path latency, and bandwidth usage in real time, ensuring maximum bandwidth utilization for each channel. The system can dynamically adjust path selection based on priority and transmission tasks, automatically switching to the optimal transmission path.

[0051] ③ Channel load balancing and failover: The system can dynamically balance the load based on the channel load and automatically select the optimal path for data transmission. If interference or a fault occurs on a certain channel, the system will automatically switch to a backup path to ensure the continuity and stability of data transmission.

[0052] (6) This invention also supports a redundant transmission mode. In application scenarios with severe electromagnetic interference and high requirements for data accuracy, redundant channels can be used to transmit copies of the same data packets. On the receiving side, the contents of these data packets are checked and compared to ensure the integrity and correctness of the data. The specific implementation is as follows:

[0053] ① Redundant Data Replica Transmission: At the transmission end, the system generates multiple replica data packets according to the redundancy strategy and transmits these replicas redundantly through different channels. Each data packet is transmitted in parallel through multiple independent channels, ensuring that even if some channels fail or are interfered with, other channels can still guarantee the complete transmission of data.

[0054] ② Redundancy Check: After receiving data packets from different channels, the receiving end uses a check algorithm (such as CRC check or hash check) to check the integrity of each received data packet. If data packets from multiple channels pass the check, the receiving end will select the data packet with the best transmission quality as the master data packet. If a data packet from a certain channel has bit errors, the receiving end will repair the data based on copies from other channels.

[0055] ③ Data packet filtering and reconstruction: After verification, the receiving end will select the data packet with the best quality from multiple redundant copies for data reconstruction, and discard the redundant copy data packets, retaining only the correct data after reconstruction.

[0056] Step 3: Reporting changes in data and intelligent data retransmission after communication interruption;

[0057] To meet the specific requirements of natural gas transmission and distribution systems for data immediacy and integrity, the open-source HarmonyOS is used as the foundation, integrating distributed event notification and intelligent scheduling modules, and introducing functional modules such as "dynamic data-triggered reporting" and "retransmission after link repair". The specific implementation is as follows:

[0058] Data is reported as soon as it changes: Utilizing HarmonyOS's distributed event management function, if the main parameters of the gas equipment (involving pressure exceeding limits or state switching) cross preset thresholds, the terminal device can dynamically transmit alarm events to the HarmonyOS message hub. Related devices and upper-layer applications can capture notifications and data in real time through an event subscription mechanism. This method avoids the inherent response lag and bandwidth waste problems of polling mode and is also superior to reporting at a fixed frequency, significantly optimizing the real-time acquisition of critical data.

[0059] Data Retransmission During Communication Interruption: If a network problem causes a communication connection interruption, the system leverages the underlying features of HarmonyOS Distributed File Management (DFS) and a dedicated distributed database (such as GaussDB for IoT) to complete local data caching, transmission resumption, and network reconnection synchronization. Once the communication connection is re-established, the system employs HarmonyOS's intelligent resource allocation scheme, integrating key factors such as network instantaneous throughput, device power supply capacity, and data timeliness. It dynamically adjusts the timing, transmission speed, and packet size of data retransmission to gradually compensate for data loss caused by the communication interruption in an optimized manner, ensuring complete data preservation and preventing high-density data retransmission during network recovery from creating a transmission bottleneck.

[0060] Step 4: Dynamically adaptive network topology;

[0061] This invention utilizes HarmonyOS soft bus technology, eliminating the need for users to concern themselves with the physical medium of device connections. Users only need to ensure the devices are on the same network to achieve dynamic networking between them. It organically integrates the open-source HarmonyOS microkernel system with distributed soft bus technology, constructing a self-adjusting network topology framework for gas stations. The specific implementation is as follows:

[0062] (1) Dynamic networking and adaptive topology construction: The soft bus dynamically constructs the network topology through the unique identifier of the device and the real-time network status. After the device is connected, the soft bus allows devices to discover each other through automatic registration and broadcasting, and automatically realizes node access, exit and dynamic adjustment of the topology. The device does not need to manually configure network parameters, which simplifies the deployment process.

[0063] (2) Network interruption and self-recovery mechanism: In the event of device failure or network interruption, the soft bus automatically re-establishes the connection and synchronizes the topology information through a self-recovery mechanism. The soft bus supports automatic re-registration of nodes to ensure rapid recovery after node failure or network failure.

[0064] In summary, the high-availability network design method for natural gas stations based on the open-source HarmonyOS proposed in this invention can solve the problems of traditional network topologies, such as reliance on hardware limitations, difficulty in achieving flexible networking and redundancy mechanisms, low transmission efficiency, and high application development difficulty. It can realize dynamic networking between devices, multipath transmission, and redundant transmission, thereby improving the system's flexibility, reliability, and development efficiency.
