Description

Technical Field

[0001] This invention relates to the field of power communication technology, specifically to a reliable communication method based on dual-mode communication. Background Technology

[0002] With the rapid development of the Internet of Things (IoT) and the Industrial Internet, the communication scenarios of various terminal devices are becoming increasingly complex, facing challenges such as power grid noise, electromagnetic interference, and changing topologies. A single communication mode can no longer meet the reliable communication needs of multiple scenarios. To improve communication robustness, dual-mode communication technology has gradually become the mainstream solution. Its core is to integrate two different types of communication modules (such as power line carrier communication and low-power wireless communication, wired communication and wireless communication, etc.) to form a complementary and redundant communication architecture. When the main communication link is blocked, it switches to the backup link to complete data transmission. Compared with a single communication mode, this significantly improves the anti-interference capability and continuity of communication.

[0003] Currently, existing dual-mode communication still has the following drawbacks in use: Current communication methods mostly adopt a passive switching mode, which only triggers the switch to the backup link after the main link is completely interrupted. This results in high switching delays, which can easily lead to data loss or transmission interruption. Furthermore, they lack the ability to predict link quality in real time and cannot dynamically adjust the communication mode according to channel quality. The main link continues to be occupied even when it is in a weak signal or high bit error rate state, affecting data integrity and communication efficiency.

[0004] Therefore, a reliable communication method based on dual-mode communication is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a reliable communication method based on dual-mode communication to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reliable communication method based on dual-mode communication, the specific steps of which are as follows: Step 1: Architecture Setup and Parameter Initialization: Select two different communication modules to build a dual-mode architecture, define the primary and backup modules and support bidirectional interaction; preset four major link quality indicators such as signal strength and three-level thresholds, configure the coordination protocol, build the control unit and establish a communication log ledger; Step 2, Link Quality Monitoring and Prediction: The control unit collects the quality data of the primary and backup links in real time and filters out abnormal values. It analyzes the quality change trend through the prediction model. When the primary link reaches the warning threshold, the backup link is woken up. When it approaches the interruption threshold, pre-switching is initiated. It can actively switch based on the comparison of the quality of the primary and backup links. Step 3, Intelligent Switching and Data Connection: A three-level switching strategy of early warning, proactive, and emergency is adopted. The status is transmitted synchronously during switching, and a cache retransmission mechanism is enabled to ensure seamless data connection. The switching latency is ≤50ms, and manual intervention in switching is supported. Step 4: Transmission Optimization and Redundancy Assurance: Dynamically adjust transmission parameters based on link quality, implement dual-link redundant transmission for critical data and single-link transmission for ordinary data, establish a data retransmission mechanism, prioritize retransmission through high-quality links, and ensure data integrity. Step 5: Review and Iterative Optimization: Regularly summarize and analyze communication logs, iteratively optimize the prediction model and switching threshold, adjust the sampling period and algorithm parameters, adapt to changes in scenarios, and improve communication reliability and adaptability.

[0007] Preferably, in step one: two differentiated communication modules are selected to form a dual-mode architecture, with a preferred communication combination adapted to the scenario, defined as the main communication module and the backup communication module, which operate independently and support bidirectional data interaction; communication parameters are initialized, link quality evaluation indicators and thresholds are preset, and normal thresholds, warning thresholds, and interruption thresholds are set. At the same time, a dual-mode collaborative communication protocol is configured to achieve data format compatibility and seamless connection between the two modes; a dual-mode collaborative control unit is built to be responsible for link quality monitoring, switching decisions and resource scheduling, and a communication log ledger is established to record link status, switching events and data transmission information to support subsequent optimization.

[0008] Preferably, in step two: the collaborative control unit collects four core quality indicators of the primary and backup links in real time, with a configurable sampling period to ensure data timeliness and filter abnormal sampling data to improve monitoring accuracy; a multi-dimensional link quality prediction model is constructed, based on historical monitoring data and current indicator values, and predicts the quality change trend of the primary link through trend analysis algorithms, identifying potential deterioration risks such as weak signals and high bit errors. When the primary link indicator reaches the warning threshold, it is determined to be a link quality degradation, and the backup link wake-up and preparation process is triggered in advance; when the indicator approaches the interruption threshold, a pre-switching mechanism is initiated to avoid passively waiting for an interruption before switching; the quality of the primary and backup links is compared in real time to generate a quality ranking result. Even if the primary link does not reach the warning threshold, if the quality of the backup link is better than that of the primary link and meets the current transmission requirements, a mode switch can be actively triggered to improve communication efficiency.

[0009] Preferably, in step three: a three-level switching strategy is set to achieve differentiated intelligent switching; a dual-mode data synchronization mechanism is adopted to maintain data format compatibility during the switching process, and the status is transmitted synchronously through the collaborative control unit to avoid data duplication or loss, ensuring seamless data connection before and after the switching, and controlling the switching latency within a preset range; manual intervention switching is supported, and operation and maintenance personnel can manually set the priority of the primary and backup links or force the switching communication mode according to the needs of the scenario, taking into account both automation and flexibility; Preferably, in step four: transmission parameters are dynamically adjusted based on link quality. When the primary and backup links are in normal condition, an efficient transmission mode is adopted to improve bandwidth utilization. When link quality deteriorates, the transmission rate is automatically reduced and the encoding method is optimized to reduce the bit error rate and ensure data integrity. A dual-link redundant transmission mechanism is established. For critical data, it can be transmitted simultaneously through the primary and backup links. The receiving end verifies data consistency to ensure that critical data is not lost. For ordinary data, a single-link transmission is adopted to balance reliability and resource utilization. A data retransmission mechanism is built. When the receiving end detects missing or incorrect data, it automatically initiates a retransmission request to the sending end and prioritizes retransmission through the link with better quality to further improve data transmission reliability.

[0010] Preferably, in step five: the collaborative control unit periodically summarizes the communication log ledger, analyzes the link quality change patterns, the rationality of switching triggers, and the transmission optimization effect; iteratively optimizes the link quality prediction model and switching threshold, and adjusts the sampling period and prediction algorithm parameters in combination with scene interference characteristics and changes in communication requirements to improve prediction accuracy and switching timeliness, reduce invalid switching, adapt to dynamic changes in the scene, update dual-mode communication combination or transmission parameters, and continuously improve the scene adaptability and communication reliability of the method.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1) This application abandons the single passive handover and designs a three-level intelligent handover strategy of early warning, active and emergency. It shortens the handover delay from the source. Early warning handover wakes up the backup link in advance to avoid handover waiting; emergency handover takes over immediately when the main link is suddenly interrupted, without waiting for interruption confirmation; active handover actively switches according to the link quality to prevent invalid occupation. Through a dual-mode data synchronization mechanism and a cache retransmission mechanism, the transmission progress and data identifiers are synchronized during handover, and incomplete data before the interruption is retransmitted. Combined with handover latency control of ≤50ms, the problems of data loss and transmission interruption during handover are completely solved, achieving seamless data connection. With the help of dual-mode architecture and collaborative protocol, the primary and backup modules operate independently and support bidirectional interaction, ensuring that the backup link can quickly respond to handover commands, providing hardware and protocol support for low-latency handover.

[0012] 2) This application constructs a full-process monitoring and prediction system. The collaborative control unit collects four major link quality indicators in real time, filters abnormal data, and predicts the deterioration trend of the main link through trend analysis algorithms. It identifies weak signals and high error risk in advance, solving the pain point of no prediction. Based on the prediction results, it achieves precise control. When the main link reaches the warning threshold, the backup link is woken up in advance, and when it is close to the interruption threshold, pre-switching is initiated to avoid the continuous occupation of the poor quality main link. At the same time, the quality of the main and backup links is compared in real time. Even if the main link does not reach the warning threshold, it can switch to a better link to improve communication efficiency and data integrity. Combined with the iterative optimization mechanism, the link data is reviewed regularly to optimize the prediction model and switching threshold, continuously improve the prediction accuracy, reduce the occupation of the poor quality main link and invalid switching, and balance data integrity and communication efficiency.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0015] Please see Figure 1 The present invention provides a technical solution: A reliable communication method based on dual-mode communication, the specific steps of which are as follows: Step 1: Architecture Setup and Parameter Initialization: Select two different communication modules to build a dual-mode architecture, define the primary and backup modules and support bidirectional interaction; preset four major link quality indicators such as signal strength and three-level thresholds, configure the coordination protocol, build the control unit and establish a communication log ledger; Step one is the prerequisite for the entire communication method. Its core function is to build the hardware architecture, clarify the operating rules, and improve the supporting infrastructure, providing hardware and parameter guarantees for subsequent link monitoring and intelligent switching. This is specifically reflected in the following: Hardware architecture implementation: Two different communication modules are selected to build a dual-mode architecture and define the primary and backup modules, which support bidirectional interaction, breaking the limitations of a single communication mode. Through module redundancy, "one primary and one backup, complementary backup" is achieved, avoiding communication failure caused by a single link interruption from the hardware level, and adapting to complex interference scenarios (such as power grid noise and electromagnetic interference). The operating rules are clearly defined: four major link quality indicators, including signal strength and bit error rate, and three levels of thresholds for normal, early warning, and interruption are preset to provide quantitative standards for subsequent link quality judgment and switching decisions, avoiding blind or delayed switching without a basis; a cooperative communication protocol is configured to solve the data format compatibility problem between the two communication modes, providing protocol support for seamless switching and two-way interaction; Control and review support: A dual-mode collaborative control unit is built as the "decision core" of the entire method, coordinating the entire process of link monitoring, switching scheduling, parameter adjustment and other operations; a communication log ledger is established to fully record the link status, switching events and data transmission information, providing data support for subsequent review analysis and model iteration.

[0016] Step 2, Link Quality Monitoring and Prediction: The control unit collects the quality data of the primary and backup links in real time and filters out abnormal values. It analyzes the quality change trend through the prediction model. When the primary link reaches the warning threshold, the backup link is woken up. When it approaches the interruption threshold, pre-switching is initiated. It can actively switch based on the comparison of the quality of the primary and backup links. The core function of step two is to monitor link status in real time, predict quality changes, and trigger backup link preparation in advance to avoid passively waiting for the primary link to be interrupted before switching. Simultaneously, it optimizes link resource usage and coordinates with the control unit to collect the four core quality indicators of the primary and backup links in real time, filtering abnormal sampled data to ensure the accuracy and timeliness of monitoring data. This provides reliable data input for subsequent predictions and decisions, avoiding misjudgments or omissions due to data deviations. Through a multi-dimensional prediction model, combined with historical monitoring data and current indicators, and using trend analysis algorithms, it identifies potential deterioration risks such as weak signals and high bit error rates in the primary link, achieving "early detection and early preparation." When the primary link reaches the warning threshold, the backup link is activated to avoid delays caused by the backup link not being ready during switching. When approaching the interruption threshold, pre-switching is initiated to completely eliminate the high latency problem of passive switching. Real-time comparison of the quality of the primary and backup links is performed. Even if the primary link does not reach the warning threshold, if the backup link has better quality and meets transmission requirements, it can actively switch to the high-quality link to avoid low communication efficiency and high data error rates caused by the poor quality of the primary link, balancing communication reliability and efficiency.

[0017] Step 3, Intelligent Switching and Data Connection: A three-level switching strategy of early warning, proactive, and emergency is adopted. The status is transmitted synchronously during switching, and a cache retransmission mechanism is enabled to ensure seamless data connection. The switching latency is ≤50ms, and manual intervention in switching is supported. Step three is crucial for connection prediction and transmission assurance. Its core function is to achieve differentiated intelligent handover based on the prediction results of step two, while simultaneously resolving data loss and duplicate transmission issues during the handover process, ensuring communication continuity. It employs a three-level handover strategy: early warning, proactive, and emergency, adapting to different link quality scenarios. Early warning handover ensures "uninterrupted standby," proactive handover selects the best option, and emergency handover provides "coverage for sudden interruptions," balancing handover timeliness and flexibility to cover various needs in complex communication scenarios. Through dual-mode collaborative protocols and hardware linkage, handover latency is controlled to ≤50ms, far lower than existing passive handover solutions, avoiding communication interruptions and data loss due to excessive handover latency, and adapting to latency-sensitive scenarios such as industrial control and power meter reading. During handover, the collaborative control unit synchronously transmits status (transmission progress, data identifier), and enables a buffer retransmission mechanism to retransmit data that was not transmitted before the interruption, while avoiding duplicate data transmission. This completely solves the pain points of data loss and poor connection during existing handover processes, ensuring data integrity.

[0018] Step 4: Transmission Optimization and Redundancy Assurance: Dynamically adjust transmission parameters based on link quality, implement dual-link redundant transmission for critical data and single-link transmission for ordinary data, establish a data retransmission mechanism, prioritize retransmission through high-quality links, and ensure data integrity. Step four optimizes transmission strategies for different data types. Through redundant design and dynamic adjustment, it further reduces the risk of data loss and bit errors while avoiding resource waste. Transmission parameters are adjusted in real time based on link quality. When the link is normal, an efficient transmission mode is used to improve bandwidth utilization; when the link deteriorates, the transmission rate is reduced and the encoding method is optimized to reduce the bit error rate, achieving "quality-adaptive transmission" that balances efficiency and reliability. For critical data such as industrial control commands and power meter reading data, dual-link redundant transmission is adopted, with the receiving end verifying data consistency to ensure that critical data is not lost. For ordinary data, single-link transmission is used to avoid the resource waste caused by dual-link transmission, balancing reliability and resource utilization. A data retransmission mechanism is established. When the receiving end detects missing or erroneous data, it proactively initiates a retransmission request, prioritizing retransmission through the link with better quality, further reducing the risk of data loss. This forms a triple guarantee of "prediction-switching-retransmission," maximizing the integrity of data transmission.

[0019] Step 5: Review and Iterative Optimization: Regularly summarize and analyze communication logs, iteratively optimize the prediction model and switching threshold, adjust the sampling period and algorithm parameters, adapt to changes in scenarios, and improve communication reliability and adaptability.

[0020] Step 5 involves iteratively refining algorithms and parameters based on full-process operational data. This allows the communication method to adapt to changing scenarios, continuously improving reliability and adaptability. Regularly summarizing link quality data, handover events, and transmission success rates from the communication log ledger helps analyze link quality change patterns, the rationality of handover triggers, and the effectiveness of transmission optimization. This accurately identifies shortcomings in existing solutions (such as prediction errors and untimely handovers). Based on the review results, the link quality prediction model is iteratively optimized to improve the accuracy of trend predictions. The three-level handover threshold and sampling period are adjusted to reduce invalid handovers and optimize handover timeliness. Transmission parameters are updated to adapt to changing scenario interference characteristics and communication requirements, making the solution more suitable for actual application scenarios. Through continuous iteration, the communication method can dynamically adapt to complex situations such as changes in scenario topology and interference intensity, breaking the limitations of "one-time design," continuously improving communication reliability and scenario adaptability, and extending the applicable lifespan of the solution.

[0021] In step one: two differentiated communication modules are selected to build a dual-mode architecture, and the communication combination adapted to the scenario is preferred. For example, in the power scenario, power line carrier communication and low-power wireless communication are used, and in the general scenario, WiFi and Bluetooth, or 4G and 5G are used. These are defined as the main communication module and the backup communication module, respectively. The two operate independently and support bidirectional data interaction. Communication parameters are initialized, and link quality evaluation indicators and thresholds are preset, including four core indicators: signal strength, bit error rate, transmission latency, and bandwidth utilization. Normal thresholds, warning thresholds, and interruption thresholds are set. For example, a bit error rate ≤1% is normal, 1%-5% is a warning, and >5% is an interruption. At the same time, a dual-mode collaborative communication protocol is configured to achieve data format compatibility and seamless connection between the two modes. A dual-mode collaborative control unit is built to be responsible for link quality monitoring, switching decisions, and resource scheduling. A communication log ledger is established to record link status, switching events, and data transmission information to support subsequent optimization.

[0022] In step two: the collaborative control unit collects four core quality indicators of the primary and backup links in real time, with a configurable sampling period (10ms-1s) to ensure data timeliness and filter abnormal sampling data to improve monitoring accuracy; a multi-dimensional link quality prediction model is constructed, based on historical monitoring data and current indicator values, and predicts the quality change trend of the primary link through trend analysis algorithms, identifying potential deterioration risks such as weak signals and high bit errors. When the primary link indicator reaches the warning threshold, it is determined that the link quality has deteriorated, and the backup link wake-up and preparation process is triggered in advance; when the indicator is close to the interruption threshold, a pre-switching mechanism is started to avoid passively waiting for an interruption before switching; the quality of the primary and backup links is compared in real time to generate a quality ranking result. Even if the primary link does not reach the warning threshold, if the quality of the backup link is better than that of the primary link and meets the current transmission requirements, a mode switch can be actively triggered to improve communication efficiency.

[0023] In step three, a three-level switching strategy is set to achieve differentiated intelligent switching: First, early warning switching: when the primary link reaches the early warning threshold, the backup link completes wake-up and parameter synchronization, remains in standby state, and the primary link transmits normally to avoid switching delay; Second, proactive switching: when the primary link quality deteriorates or the backup link becomes better, proactive switching to the backup link is initiated, synchronously interrupting the primary link data transmission to reduce resource waste; Third, emergency switching: when the primary link is suddenly interrupted, the backup link is immediately triggered to take over, and the data caching mechanism is activated to resend the data that was not transmitted before the interruption; A dual-mode data synchronization mechanism is adopted to maintain data format compatibility during the switching process, and the transmission status, such as transmission progress and data identification, is synchronized through the collaborative control unit to avoid data duplication or loss, ensuring seamless data connection before and after the switch, and the switching latency is controlled within a preset range (≤50ms); Manual intervention switching is supported, and maintenance personnel can manually set the priority of the primary and backup links or force a switch of communication modes according to the needs of the scenario, taking into account both automation and flexibility; In step four: transmission parameters are dynamically adjusted based on link quality. When the primary and backup links are in normal condition, an efficient transmission mode is adopted to improve bandwidth utilization. When link quality deteriorates, the transmission rate is automatically reduced and the encoding method is optimized to reduce the bit error rate and ensure data integrity. A dual-link redundant transmission mechanism is established. For critical data, such as industrial control commands and power meter reading data, transmission can be carried out simultaneously through the primary and backup links. The receiving end verifies data consistency to ensure that critical data is not lost. For ordinary data, single-link transmission is adopted to balance reliability and resource utilization. A data retransmission mechanism is built. When the receiving end detects missing or incorrect data, it automatically initiates a retransmission request to the sending end and prioritizes retransmission through the link with better quality to further improve data transmission reliability.

[0024] In step five: the collaborative control unit periodically summarizes communication logs, including link quality data, handover events, data transmission success rates, and other information, analyzes the patterns of link quality changes, the rationality of handover triggers, and the effects of transmission optimization; iteratively optimizes the link quality prediction model and handover threshold, and adjusts the sampling period and prediction algorithm parameters based on scene interference characteristics and changes in communication requirements to improve prediction accuracy and handover timeliness, reduce invalid handovers, adapt to dynamic changes in the scene, update dual-mode communication combinations or transmission parameters, and continuously improve the method's scene adaptability and communication reliability.
