Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a method and system for collaborative data processing via a dual-mode communication system. Background Technology

[0002] IoT terminals are typically deployed in basements, mobile vehicles, remote mountainous areas, or structurally complex buildings, where the wireless communication environment is dynamic and unpredictable. Traditional communication methods suffer from the following problems: 1) The signal quality of public networks such as cellular networks is greatly affected by factors such as base station load, building obstruction, weather changes, and terminal characteristics, with the possibility of unpredictable momentary interruptions or signal fading. 2) The link quality of local networks such as LoRa is dynamically affected by factors such as transmission distance, terrain features, the material of obstructions, and environmental electromagnetic interference, resulting in unpredictable communication blind spots. 3) In the "LoRa gateway centralized forwarding" scheme commonly used in traditional LoRa communication architectures, the LoRa gateway needs to pre-plan the data structure, package the data of all subordinate LoRa nodes, and upload it uniformly via 4G. The server then needs to unpack and distribute the data according to corresponding rules. The essence of this scheme is "centralized data packaging and unpacking," and its system architecture is static and tightly coupled. When the network topology changes, such as adding sensor nodes or adjusting the data acquisition frequency, the gateway's packing logic and the server's unpacking logic must be modified simultaneously, resulting in poor system scalability, high operation and maintenance costs, and an inability to adapt to the common needs of dynamic access for IoT devices.

[0003] In summary, communication solutions relying on a single network inherently place system reliability on a dynamic and uncontrollable variable, posing a very high risk. Existing dual-mode backup solutions often employ simple, static switching logic, failing to intelligently address these dynamic changes. Furthermore, the switching process is opaque to applications and devices, exhibiting poor scalability and high maintenance costs, thus failing to fundamentally solve the problem. Therefore, there is an urgent need in existing technologies for a solution that can proactively sense dynamic changes in network status and intelligently and smoothly perform identity and data collaboration across heterogeneous networks, in order to build a more reliable, application-transparent, and low-maintenance IoT data transmission system. Summary of the Invention

[0004] One of the objectives of this invention is to provide a method and system for collaborative data processing via a dual-mode communication system.

[0005] According to one aspect of this application, a method for collaborative data processing via a dual-mode communication system is provided. The dual-mode communication system includes a dual-mode acquisition terminal, a dual-mode relay terminal, and a network device. Both the dual-mode acquisition terminal and the dual-mode relay terminal have communication functions for a first communication link and a second communication link. The dual-mode acquisition terminal and the dual-mode relay terminal each include a first communication module and a second communication module. The method is applied to the network device and includes: The network device receives uplink data uploaded through the first communication link; wherein, the uplink data includes the data collected by the dual-mode acquisition terminal, the network identity parameters of the dual-mode acquisition terminal, and the acquisition terminal identifier of the dual-mode acquisition terminal; If the dual-mode acquisition terminal adopts the first communication mode, the network device directly maps the acquired data to the service record of the dual-mode acquisition terminal based on the acquisition terminal identifier; wherein, the uplink data is obtained through the first communication link between the network device and the dual-mode acquisition terminal; or the uplink data is obtained through the first communication link between the network device and the target dual-mode relay terminal, the first communication link being established by the target dual-mode relay terminal using the network identity parameters of the dual-mode acquisition terminal and the network device, so as to realize the identity proxy of the target dual-mode relay terminal to the dual-mode acquisition terminal.

[0006] According to another aspect of this application, a computer device is provided, including a memory and a processor, wherein a computer program capable of being loaded by the processor and executing the methods described above is stored in the memory.

[0007] According to another aspect of this application, a computer-readable storage medium is provided, storing a computer program that can be loaded by a processor and executed as described above.

[0008] Compared with existing technologies, the dual-mode communication system of this application includes a dual-mode acquisition terminal, a dual-mode relay terminal, and a network device. Both the dual-mode acquisition terminal and the dual-mode relay terminal have communication functions for a first communication link and a second communication link. When the dual-mode acquisition terminal adopts the first communication mode, this solution enables the target dual-mode relay terminal to send uplink data to the network device on behalf of the dual-mode acquisition terminal by including the network identity parameter of the dual-mode acquisition terminal to which the acquisition data belongs in the uplink data. Therefore, when the network device receives uplink data uploaded through the first communication link, regardless of whether the uplink data was sent to the network device by the dual-mode acquisition terminal through its own first communication module or by the target dual-mode relay terminal through its own first communication module, the network device can directly map the acquisition data in the uplink data to the service record of the dual-mode acquisition terminal based on the acquisition terminal identifier included in the uplink data. Regardless of network quality in the first communication mode, the dual-mode acquisition terminal can send uplink data to network devices. Furthermore, when the first communication mode uses a heterogeneous network (such as a LoRa network), the network devices are unaware of the switching between the heterogeneous network and the uplink data sender. This fundamentally solves the inherent problems of "static planning, tight coupling, and difficulty in expansion" in traditional LoRa gateway solutions. Through an identity proxy mechanism, it constructs a flexible, dynamic, and adaptive IoT data transmission system that can easily cope with continuous changes in device scale and network topology.

[0016] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0017] refer to Figure 1This invention provides a flowchart of a method for collaborative data processing via a dual-mode communication system. The dual-mode communication system includes a dual-mode acquisition terminal, a dual-mode relay terminal, and a network device. Both the dual-mode acquisition terminal and the dual-mode relay terminal have communication functions via a first communication link and a second communication link. The dual-mode acquisition terminal and the dual-mode relay terminal each include a first communication module and a second communication module, respectively. The method is applied to the network device and includes steps S11 and S12. In step S11, the network device receives uplink data uploaded via the first communication link. The uplink data includes data acquired by the dual-mode acquisition terminal and data from the dual-mode acquisition terminal. The network identity parameters and the acquisition terminal identifier of the dual-mode acquisition terminal are used. In step S12, if the dual-mode acquisition terminal adopts the first communication mode, the network device directly maps the acquired data to the service record of the dual-mode acquisition terminal according to the acquisition terminal identifier. Uplink data is obtained through the first communication link between the network device and the dual-mode acquisition terminal; or uplink data is obtained through the first communication link between the network device and the target dual-mode relay terminal. The first communication link is established by the target dual-mode relay terminal using the network identity parameters of the dual-mode acquisition terminal and the network device to realize the identity proxy of the target dual-mode relay terminal for the dual-mode acquisition terminal. In some embodiments, the first communication link includes, but is not limited to, 4G, 5G, and other cellular network communication links, and the second communication link includes, but is not limited to, LoRa (Long Range) communication links. In some embodiments, the first communication module includes, but is not limited to, 4G, 5G, and other cellular network modules, and the second communication module includes, but is not limited to, LoRa and other long-distance communication modules. For example, the dual-mode acquisition terminal includes a 4G module and a LoRa module, and the dual-mode relay terminal also includes a 4G module and a LoRa module.

[0018] Specifically, in step S11, the network device receives uplink data uploaded through the first communication link; wherein, the uplink data includes the data collected by the dual-mode acquisition terminal, the network identity parameters of the dual-mode acquisition terminal, and the acquisition terminal identifier of the dual-mode acquisition terminal. In some embodiments, the uplink data includes, but is not limited to, the data that the dual-mode acquisition terminal needs to send out. For example, the data that the dual-mode acquisition terminal needs to send to the network device or the target dual-mode relay terminal. In some embodiments, the network identity parameters include, but are not limited to, the authentication information required when the dual-mode acquisition terminal establishes a connection with the network device through the first communication link, and the authentication information includes, but is not limited to, username, password, client identifier, subscription topic, etc. In some embodiments, the collected data includes, but is not limited to, sensor data. For example, sensor data is collected and acquired through the dual-mode acquisition terminal. In some embodiments, the first communication link for uplink data is established by the dual-mode acquisition terminal and the network device; in other words, the network device receives the uplink data uploaded by the dual-mode acquisition terminal through its own first communication module. In other words, the first communication link for uplink data is established by the target dual-mode relay terminal and the network device; in other words, the network device receives the uplink data uploaded by the target dual-mode relay terminal through its own first communication module. For a detailed explanation of this part, please refer to the corresponding embodiments below, which will not be repeated here. In some embodiments, the data acquisition terminal identifier includes, but is not limited to, the device identifier of a dual-mode data acquisition terminal.

[0019] In step S12, if the dual-mode acquisition terminal adopts the first communication mode, the network device directly maps the acquired data to the service record of the dual-mode acquisition terminal according to the acquisition terminal identifier; wherein, the uplink data is obtained through the first communication link between the network device and the dual-mode acquisition terminal; or the uplink data is obtained through the first communication link between the network device and the target dual-mode relay terminal, the first communication link being established by the target dual-mode relay terminal using the network identity parameters of the dual-mode acquisition terminal and the network device, so as to realize the identity proxy of the target dual-mode relay terminal for the dual-mode acquisition terminal. In some embodiments, the first communication mode includes, but is not limited to, the network device directly receiving the uplink data sent by the dual-mode acquisition terminal through its own first communication module. For example, under normal circumstances of the first communication mode (e.g., when the communication quality of the first communication link between the dual-mode acquisition terminal and the network device does not meet the first preset condition), the uplink data is obtained through the first communication link between the network device and the dual-mode acquisition terminal. Specifically, the dual-mode acquisition terminal directly sends the uplink data to the network device through its own first communication module. For example, in abnormal situations of the first communication mode (e.g., when the communication quality of the first communication link between the dual-mode acquisition terminal and the network device meets the first preset condition), uplink data is obtained through the first communication link between the network device and the target dual-mode relay terminal. Specifically, when the communication quality of the first communication link between the dual-mode acquisition terminal and the network device meets the first preset condition, the target dual-mode relay terminal corresponding to the dual-mode acquisition terminal obtains uplink data through the second communication link with the dual-mode acquisition terminal. The target dual-mode relay terminal establishes a first communication link with the network device using its own first communication module and the network identity parameters of the dual-mode acquisition terminal, thereby acting as an agent for the dual-mode acquisition terminal to send uplink data to the network device. For a detailed explanation of this part, please refer to the corresponding embodiments below, which will not be repeated here. Regardless of whether the first communication link for uplink data transmission is established between the dual-mode acquisition terminal and the network device, or between the target dual-mode relay terminal and the network device, the network device can directly map the acquired data in the uplink data to the service record of the dual-mode acquisition terminal based on the acquisition terminal identifier in the uplink data. This ensures that the dual-mode acquisition terminal can send uplink data to the network device regardless of the network quality in the first communication mode. Furthermore, when the first communication mode uses a heterogeneous network (e.g., using both 4G and LoRa networks), the network device remains unaware of the switching between heterogeneous networks and the uplink data sender. This changes the traditional approach of using 4G or LoRa alone, and also eliminates the need for a LoRa gateway to centrally package data from multiple LoRa sensors, requiring the network device to pre-deploy corresponding unpacking rules. This achieves a "plug-and-play" effect for the acquisition terminal, greatly improving the system's scalability.

[0020] In some embodiments, the first communication mode includes the network device directly receiving uplink data sent by the dual-mode acquisition terminal through its own first communication module; the network device receiving uplink data uploaded through the first communication link includes: the network device receiving uplink data forwarded by the first communication module of the target dual-mode relay terminal; wherein, the uplink data is the communication quality of the first communication link between the dual-mode acquisition terminal and the network device monitored in real time by the dual-mode acquisition terminal; when the communication quality of the first communication link meets a first preset condition, the dual-mode acquisition terminal sends the uplink data to the second communication module of the target dual-mode relay terminal through its own second communication module; the target dual-mode relay terminal obtains the uplink data and sends it to the network device using the network identity parameters of the dual-mode acquisition terminal. For example, the first communication mode includes normal and abnormal situations. Under normal conditions of the first communication mode, the dual-mode acquisition terminal sends uplink data to the network device through its own first communication module. This embodiment focuses on how the network device receives uplink data uploaded through the first communication link under abnormal conditions of the first communication mode. Specifically, under normal conditions in the first communication mode, the dual-mode acquisition terminal establishes a first communication link with the network device using its own network identity parameters and monitors the communication quality of this first communication link in real time. When the communication quality of the first communication link meets a first preset condition, i.e., under abnormal conditions in the first communication mode, the dual-mode acquisition terminal sends uplink data to the target dual-mode relay terminal corresponding to it through its own second communication module. The target dual-mode relay terminal receives the uplink data through its own second communication module. Then, the target dual-mode relay terminal parses the uplink data to obtain the network identity parameters of the dual-mode acquisition terminal and uses these parameters to establish a first communication link with the network device. Finally, the target dual-mode relay terminal sends the uplink data of the dual-mode acquisition terminal to the network device through the first communication link it has established with the network device. The target dual-mode relay terminal establishes a first communication link with the network device using the network identity parameters of the dual-mode acquisition terminal. This achieves identity proxying of the dual-mode acquisition terminal by the target dual-mode relay terminal. The network device still receives uplink data from the dual-mode acquisition terminal through the first communication link and directly maps the acquired data in the uplink data to the service record of the dual-mode acquisition terminal based on the acquisition terminal identifier in the uplink data. In some embodiments, the first preset conditions include, but are not limited to, continuous packet loss, latency spikes, and unexpected TCP link disconnection. In some embodiments, the target dual-mode relay terminal corresponding to the dual-mode acquisition terminal includes, but is not limited to, the dual-mode acquisition terminal being within the management domain of the target dual-mode relay terminal. For example, one target dual-mode relay terminal corresponds to one or more dual-mode acquisition terminals, meaning that each of these one or more dual-mode acquisition terminals can establish a second communication link (LoRa communication link) with the target dual-mode relay terminal through their respective second communication modules (LoRa).

[0021] In some embodiments, the method further includes step S13 (not shown), in which the network device caches the downlink data pre-sent to the dual-mode acquisition terminal in a database and establishes an association between the acquisition terminal identifier of the dual-mode acquisition terminal and the downlink data in the database; in response to a first event information of receiving uplink data through a first communication link, the network device sends the downlink data to the dual-mode acquisition terminal based on the currently established first communication link. In some embodiments, the downlink data includes, but is not limited to, the data that the network device needs to send to the dual-mode acquisition terminal. For example, the downlink data includes, but is not limited to, the acquisition frequency and reporting frequency of the dual-mode acquisition terminal. In this embodiment, the network device caches the downlink data corresponding to the dual-mode acquisition terminal in a database. When the network device receives uplink data uploaded through the first communication link, it triggers the network device to send the downlink data corresponding to the dual-mode acquisition terminal to the dual-mode acquisition terminal. This embodiment solves the problem that when uplink data is uploaded to the network device through the first communication link established between the target dual-mode relay terminal and the network device, the target dual-mode relay terminal is offline and cannot send the downlink data to the dual-mode acquisition terminal by responding to the first event information of receiving uplink data and sending the corresponding downlink data to the dual-mode acquisition terminal through the currently established first communication link. For example, a target dual-mode relay terminal may correspond to multiple dual-mode acquisition terminals. When the first communication link between dual-mode acquisition terminal A and the network device meets a first preset condition, the target dual-mode relay terminal uses the network identity parameters of dual-mode acquisition terminal A to establish a first communication link with the network device. When the first communication link between dual-mode acquisition terminal B and the network device meets the first preset condition, the target dual-mode relay terminal uses the network identity parameters of dual-mode acquisition terminal B to establish a first communication link with the network device. In other words, the network identity parameters used by the target dual-mode relay terminal are variable, which can cause the target dual-mode relay terminal to go offline. In this embodiment, in response to the first event information of receiving uplink data through the first communication link, the network device directly sends the downlink data that needs to be sent to the dual-mode acquisition terminal through the currently established first communication link to the target dual-mode relay terminal, so that the target dual-mode relay terminal can send the downlink data to the dual-mode acquisition terminal through the second communication link it has established with the dual-mode acquisition terminal. This achieves 100% successful transmission of downlink data. For example, when the first communication link is established between a dual-mode acquisition terminal and a network device, the network device, in response to the received uplink data uploaded through the first communication link, directly sends the downlink data of the dual-mode acquisition terminal to the dual-mode acquisition terminal through the first communication link. As another example, when the first communication link is established between a target dual-mode relay terminal and a network device, the network device, in response to the received uplink data uploaded through the first communication link, sends the downlink data of the dual-mode acquisition terminal to the target dual-mode relay terminal through the first communication link.The target dual-mode relay terminal then sends the downlink data to the dual-mode acquisition terminal through the second communication link it establishes with the dual-mode acquisition terminal.

[0022] In some embodiments, the method further includes step S14 (not shown) before sending downlink data to the dual-mode acquisition terminal. In step S14, the network device queries the database to see if there is downlink data associated with the acquisition terminal identifier included in the uplink data. If downlink data associated with the acquisition terminal identifier exists, the downlink data is sent to the dual-mode acquisition terminal based on the currently established first communication link. For example, the database records multiple acquisition terminal identifiers and the mapping relationship of downlink data corresponding to each acquisition terminal identifier. The network device obtains the acquisition terminal identifier by parsing the uplink data, queries the database to see if the acquisition terminal identifier corresponds to downlink data to be sent, and if so, sends the downlink data to the dual-mode acquisition terminal through the current first communication link, or sends it to a target dual-mode relay terminal, which then sends it to the dual-mode acquisition terminal. In some embodiments, after the downlink data corresponding to the dual-mode acquisition terminal is sent out, the downlink data corresponding to the dual-mode acquisition terminal is deleted from the database to update the database.

[0023] In some embodiments, the method further includes step S15 (not shown). In step S15, if the dual-mode acquisition terminal adopts the second communication mode, the network device, in response to receiving the second event information of uplink data, queries the target dual-mode relay terminal corresponding to the dual-mode acquisition terminal from the network topology relationship according to the acquisition terminal identifier. Then, through the first communication link between the network device and the target dual-mode relay terminal, the downlink back-injection data corresponding to the uplink data is directionally back-injected to the target dual-mode relay terminal. This allows the target dual-mode relay terminal to parse the downlink back-injection data and merge the parsed acquisition data into the local device data monitoring record of the target dual-mode relay terminal based on the acquisition terminal identifier, thereby achieving automatic data integrity repair of the local view. In some embodiments, the second communication mode includes normal and abnormal conditions. Regardless of whether the second communication mode is in a normal or abnormal state, the target dual-mode relay terminal maintains a first communication link with the network device through its own first communication module. In some embodiments, the network device records network topology relationships, including the target dual-mode relay terminals corresponding to each dual-mode acquisition terminal (e.g., the association between the acquisition terminal identifier of each dual-mode acquisition terminal and the relay terminal identifier of the target dual-mode relay terminal). For example, under normal conditions of the second communication mode, the dual-mode acquisition terminal establishes a second communication link with the target dual-mode relay terminal through its own second communication module to send uplink data to the target dual-mode relay terminal. This embodiment focuses on the abnormal conditions of the second communication mode. For example, under abnormal conditions of the second communication mode, if the communication quality of the second communication link between the dual-mode acquisition terminal and the target dual-mode relay terminal meets a second preset condition, the dual-mode acquisition terminal directly sends uplink data to the network device through its own first communication module. In response to the second event information of receiving the uplink data, the network device queries the target dual-mode relay terminal corresponding to the dual-mode acquisition terminal from the network topology relationships to send the downlink backfeed data corresponding to the uplink data to the target dual-mode relay terminal through the first communication link between the network device and the target dual-mode relay terminal. In some embodiments, the downlink back-injection data includes uplink data (in other words, the network device directly sends uplink data to the target dual-mode relay terminal). In other embodiments, the downlink back-injection data may also include a back-injection marker to indicate to the target dual-mode relay terminal that the data is from a missing dual-mode acquisition terminal. In some embodiments, the local device data monitoring record of the target dual-mode relay terminal records the correspondence between the acquisition terminal identifier of the dual-mode acquisition terminal corresponding to the target dual-mode relay terminal and the device data, so that the target dual-mode relay terminal and the acquisition terminal identifier of the dual-mode acquisition terminal in the downlink back-injection data can obtain the device data corresponding to the dual-mode relay terminal from the local device data monitoring record, and map the acquisition data in the downlink back-injection data to the device data. It should be noted here that the first communication mode and the second communication mode described above are parallel communication modes.For example, if the dual-mode acquisition terminal adopts the first communication mode, the methods of the embodiments for the first communication mode described above are executed; if the dual-mode acquisition terminal adopts the second communication mode, the methods of the embodiments for the second communication mode are executed. Regardless of whether the dual-mode acquisition terminal adopts the first or second communication mode, the network device receives uplink data through the first communication link.

[0024] In some embodiments, the second communication mode includes a dual-mode acquisition terminal sending uplink data to a target relay terminal via its own second communication module, and a network device receiving uplink data uploaded through a first communication link. This includes the network device receiving uplink data sent by the first communication module of the dual-mode acquisition terminal; wherein the uplink data represents the communication quality of the second communication link between the dual-mode acquisition terminal and the target dual-mode relay terminal, as monitored by the dual-mode acquisition terminal; when the communication quality of the second communication link meets a second preset condition, the dual-mode acquisition terminal directly sends the uplink data to the network device via its own first communication module. For example, under normal conditions in the second communication mode, while sending uplink data to the target dual-mode relay terminal via the second communication link between the dual-mode acquisition terminal and the target dual-mode relay terminal, the dual-mode acquisition terminal monitors the communication quality of the second communication link in real time. When the communication quality of the second communication link meets the second preset condition, the dual-mode acquisition terminal directly sends the uplink data to the network device via its own first communication module. In some embodiments, the second preset condition includes, but is not limited to, an RSSI value continuously below a threshold, ACK confirmation timeout, etc.

[0025] In some embodiments, the network topology includes a logical attribution mapping between a dual-mode acquisition terminal and a target dual-mode relay terminal, so as to determine the target dual-mode relay terminal to which the dual-mode acquisition terminal belongs from the network topology based on the acquisition terminal identifier of the dual-mode acquisition terminal. The network topology is obtained by the following methods: dynamically generated based on the historical second communication link connection between the dual-mode acquisition terminal and the target dual-mode relay terminal; or generated based on the geographical location and preset management domain static configuration of the dual-mode acquisition terminal. In some embodiments, the network device extracts application layer information and transport layer information by parsing the received service data packets. The application layer information indicates the source device that generated the service data packet (i.e., the first device identity identifier of the dual-mode acquisition terminal); the transport layer information indicates the physical transmission source that directly sends the service data packet to the network device (i.e., the physical link identifier of the dual-mode relay terminal). Based on the above parsing results, the network device determines that there is a valid communication connection between the dual-mode acquisition terminal and the dual-mode relay terminal, thereby establishing the dual-mode relay terminal corresponding to the physical transmission source as the target dual-mode relay terminal to which the dual-mode acquisition terminal belongs, and updating it in the network topology. In other embodiments, a network topology is pre-configured based on the physical deployment location of the dual-mode acquisition terminals and a preset management area. For example, dual-mode relay terminal A is deployed on the "top floor of Building 1," and its LoRa signal coverage area is defined as the "Building 1 management domain"; dual-mode acquisition terminals B1 to B10 are installed on "floors 1 to 10 of Building 1." In the initialized network topology table, the network devices directly and statically bind dual-mode acquisition terminals B1 to B10 to the name of dual-mode relay terminal A. In some embodiments, although dual-mode acquisition terminals B1 to B10 have not yet engaged in actual data communication with dual-mode relay terminal A during the system initialization phase, based on the overlap of geographical locations and the affiliation of management domains, dual-mode acquisition terminals B1 to B10 belong to dual-mode relay terminal A in the network topology.

[0026] Figure 2The diagram illustrates the structure of a network device according to an embodiment of this application. The network device includes a primary module and a secondary module. The primary module is used to receive uplink data uploaded through a first communication link. The uplink data includes data collected by a dual-mode acquisition terminal, network identity parameters of the dual-mode acquisition terminal, and an acquisition terminal identifier of the dual-mode acquisition terminal. The secondary module is used to map the collected data to the service record of the dual-mode acquisition terminal directly according to the acquisition terminal identifier if the dual-mode acquisition terminal adopts a first communication mode. The uplink data is obtained through the first communication link between the network device and the dual-mode acquisition terminal; or the uplink data is obtained through the first communication link between the network device and a target dual-mode relay terminal. The first communication link is established by the target dual-mode relay terminal using the network identity parameters of the dual-mode acquisition terminal and the network device to realize the identity proxy of the target dual-mode relay terminal for the dual-mode acquisition terminal.
