Description

Technical Field

[0001] This invention relates to the field of communication technology, and is a full-duplex multipath communication system and method. Background Technology

[0002] In existing communication systems, half-duplex communication mode allows communication nodes to only send or receive at any given time, resulting in low communication efficiency and failing to meet the real-time requirements of applications such as industrial automation control and remote high-definition video transmission. While traditional full-duplex communication systems can achieve simultaneous sending and receiving, they often rely on a single communication path. When this path is interfered with or fails, communication quality is severely affected, and the stability and reliability of data transmission are difficult to guarantee. Furthermore, with the rapid increase in the number of communication devices and the explosive growth of data traffic, existing communication systems are prone to signal congestion and increased latency when handling multiple concurrent communications.

[0003] The aforementioned problems are particularly prominent in power grid communication scenarios, especially in the application of power grid drones. In scenarios such as power grid inspection and fault repair, drones need to transmit high-definition inspection images and equipment status data to the ground control center in real time, while receiving instructions from the control center (such as flight path adjustments and shooting parameter modifications), which places extremely high demands on the real-time performance and stability of communication. Currently, most power grid drones use half-duplex communication mode or single-path full-duplex mode, which has the following significant shortcomings: In half-duplex mode, drones cannot receive control commands in a timely manner when sending inspection data, which may lead to response delays in emergency situations (such as obstacle avoidance and response to sudden weather), posing safety hazards; When relying on a single communication path (such as a wireless link in a specific frequency band), if encountering electromagnetic interference from power grid equipment, complex terrain obstruction (such as mountainous areas or dense building clusters), or signal blind spots, data transmission interruptions or packet loss may occur, resulting in lost inspection data and invalid control commands, seriously affecting inspection efficiency; There are many high-voltage equipment, transformers, and other strong electromagnetic interference sources in the power grid environment. Traditional communication systems have limited ability to suppress self-interference and external interference, which can easily lead to an increased bit error rate in transmitted data (such as screen distortion in high-definition images and misjudgment of equipment parameters), affecting the accuracy of power grid status assessment; With the upgrading of equipment carried by drones (such as multispectral cameras and thermal imagers), the amount of transmitted data has surged (single inspection data can reach tens of gigabytes), and the bandwidth of a single communication path is insufficient to meet the real-time transmission needs of large data volumes, resulting in data backlog and transmission delays.

[0004] Therefore, there is an urgent need for a full-duplex multipath communication system and method to solve the above-mentioned problems in the application of UAVs in power grids and improve the reliability and intelligence level of power grid communication. Summary of the Invention

[0005] This invention provides a full-duplex multipath communication system and method that overcomes the shortcomings of the prior art. It can effectively solve the problems of low efficiency of existing half-duplex communication and poor anti-interference of traditional full-duplex communication in power grid drone applications, which cannot meet the requirements of high real-time scenarios.

[0006] One of the technical solutions of this invention is achieved through the following measures: a full-duplex multipath communication system, comprising: At least two communication nodes, each equipped with a full-duplex communication module, for transmitting and receiving signals simultaneously at the same time and frequency; The multi-path selection module, connected to the full-duplex communication module, is used to select the optimal path or combination of paths from multiple available communication paths for data transmission based on the real-time status information of the communication link. An interference cancellation module, located within a communication node, is used to eliminate or suppress self-interference signals generated during full-duplex communication as well as external interference signals from other communication nodes. The control and coordination module is connected to the full-duplex communication module, multipath selection module, and interference cancellation module. It is used to perform unified control and coordination of each module to ensure stable system operation.

[0007] The following are further optimizations and / or improvements to one of the above-mentioned inventive technical solutions: The aforementioned full-duplex communication module may include: The transceiver antenna assembly consists of at least two antennas, one for transmitting and the other for receiving signals. The antennas have good directivity and gain characteristics to enhance signal transmission performance. The radio frequency front-end circuit, connected to the transceiver antenna assembly, is used to amplify the power and up-convert the frequency of the transmitted signal, and to amplify the noise and down-convert the frequency of the received signal. The baseband processing unit, connected to the radio frequency front-end circuit, is used to perform operations such as modulation, encoding, demodulation, and decoding of baseband signals to achieve effective data transmission and reception.

[0008] The multipath selection module described above can perform path selection by monitoring the following real-time status information of the communication link: Signal strength: Real-time monitoring of the received signal strength on each path, prioritizing paths with higher signal strength; Bit error rate: Calculate the bit error rate of data transmitted along each path and prioritize paths with low bit error rates. Delay time is the time it takes for data to travel along each path, and the path with the shortest delay time is selected. Bandwidth utilization is analyzed to determine the bandwidth usage of each path, prioritizing paths with low bandwidth utilization and sufficient remaining bandwidth.

[0009] The interference cancellation module described above can employ at least one of the following interference cancellation methods: Analog domain interference cancellation is achieved by employing adaptive cancellation technology in the RF front-end circuit to construct a cancellation signal with the same amplitude but opposite phase as the interference signal, thereby subtracting the interference signal from the received signal. Digital domain interference cancellation is based on digital signal processing algorithms. It analyzes and processes the received signal, estimates the characteristics of the interference signal, and removes the interference components from the received signal. Spatial domain interference cancellation utilizes the spatial characteristics of transceiver antenna components. By adjusting the antenna's orientation or employing smart antenna technology, the antenna's sensitivity to receiving interference signals is reduced, thereby minimizing the impact of interference signals.

[0010] The aforementioned control and coordination module can have the following functions: Initialization configuration involves setting parameters and initializing the full-duplex communication module, multipath selection module, and interference cancellation module during system startup. Real-time monitoring continuously monitors the working status of each module, collects and analyzes relevant data, and determines whether the system is operating normally. Dynamic adjustment: Based on changes in system operating status and communication requirements, the working parameters of each module are dynamically adjusted to optimize system performance; Fault diagnosis and recovery: When a system malfunctions, the fault point can be quickly located and corresponding recovery measures can be taken to ensure uninterrupted system operation.

[0011] The aforementioned communication node may also include a caching module, which is connected to the full-duplex communication module and the multi-path selection module. The caching module is used to temporarily store data to be sent or received during data transmission to address the problem of mismatch between sudden traffic and transmission rate during communication.

[0012] The aforementioned full-duplex multipath communication system may also include an encryption and decryption module, which is located within the communication node and connected to the full-duplex communication module. This module is used to encrypt the transmitted data and decrypt the received data, thereby ensuring the security of data transmission.

[0013] The aforementioned communication nodes can be connected wirelessly, and the communication frequency bands include, but are not limited to, 2.4 GHz, 5 GHz, and other licensed frequency bands that comply with communication standards.

[0014] The aforementioned full-duplex multipath communication system can support a variety of communication protocols, including but not limited to TCP / IP and UDP protocols, to adapt to different application scenarios and communication needs.

[0015] The second technical solution of the present invention is achieved through the following measures: a multipath communication method based on full-duplex communication, comprising the following steps: Enable full-duplex communication mode: The communication node enables full-duplex communication, enabling simultaneous data transmission and reception; Real-time multi-path monitoring: Real-time monitoring of multiple available communication paths to obtain signal strength, interference value, and transmission rate parameters for each path; Dynamic path selection: Based on the monitored parameters, at least one target transmission path is determined from multiple communication paths through a preset optimization algorithm; Data fragmentation transmission: The data to be sent is fragmented according to the number and transmission capacity of the target transmission paths, and then sent synchronously on each target transmission path in full-duplex mode; Receive and merge processing: At the receiving end, the fragmented data transmitted from each target transmission path is received synchronously in full-duplex mode, and the fragmented data is merged to restore the complete data.

[0016] This invention improves communication efficiency and meets real-time requirements. Multiple full-duplex communication nodes in the system have the ability to simultaneously send and receive data, breaking through the limitation of half-duplex communication where "only one can be sent or received at a time," fundamentally improving the communication efficiency of a single node. It ensures the stability and reliability of data transmission. Through a multi-path communication design, the system no longer relies on a single communication path. The path selection module monitors parameters such as signal strength, interference, and transmission rate of each path in real time and selects the optimal or multiple better paths for transmission. When a path is interfered with, malfunctions, or its transmission quality degrades, the system can quickly switch to other available paths, avoiding the "all-or-nothing" problem of traditional single-path communication. It enhances anti-interference capabilities and optimizes communication quality. The self-interference cancellation module effectively eliminates interference from the transmitted signal to the received signal in full-duplex communication through dual processing in the analog and digital domains. The analog domain self-interference cancellation unit first reduces most of the interference through hardware circuitry, and the digital domain self-interference cancellation unit then eliminates residual interference through digital signal processing, significantly improving the purity of the received signal. This enables nodes to accurately receive signals even in complex electromagnetic environments (such as industrial workshops and densely populated urban areas), reducing communication quality degradation caused by self-interference. In power grid and drone applications, this invention improves efficiency and meets real-time requirements through full-duplex communication for simultaneous transmission and reception. Multi-path selection avoids reliance on a single path, ensuring stable and reliable transmission. An interference cancellation module enhances anti-interference capabilities to adapt to complex environments. Data fragmentation transmission accommodates large data volumes. An encryption module ensures security, and a caching module handles unexpected situations. Overall, this invention improves the intelligence and operational efficiency of power grid and drone communication. Attached Figure Description

[0018] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0019] The present invention will be further described below with reference to embodiments: Example 1: Please refer to Figure 1 This embodiment provides a full-duplex multipath communication system, including: At least two communication nodes, each equipped with a full-duplex communication module, for transmitting and receiving signals simultaneously at the same time and frequency; The multi-path selection module, connected to the full-duplex communication module, is used to select the optimal path or combination of paths from multiple available communication paths for data transmission based on the real-time status information of the communication link.

[0024] In this embodiment of the invention, the communication node further includes a caching module, which is connected to the full-duplex communication module and the multi-path selection module. The caching module is used to temporarily store data to be sent or received during data transmission to address the problem of mismatch between sudden traffic and transmission rate during the communication process.

[0025] In this embodiment of the invention, the full-duplex multipath communication system further includes an encryption and decryption module, which is located within the communication node and connected to the full-duplex communication module. This module is used to encrypt the transmitted data and decrypt the received data, thereby ensuring the security of data transmission.

[0026] In this embodiment of the invention, the communication nodes are connected by wireless communication, and the communication frequency bands include, but are not limited to, 2.4 GHz, 5 GHz and other industrial, scientific and medical (ISM) frequency bands, as well as other licensed frequency bands that comply with communication specifications.

[0027] In this embodiment of the invention, the full-duplex multipath communication system supports multiple communication protocols, including but not limited to TCP / IP and UDP protocols, to adapt to different application scenarios and communication needs.

[0028] A full-duplex multipath communication system includes at least two communication nodes, each equipped with a full-duplex communication module for simultaneous signal transmission and reception at the same time and frequency. A multipath selection module, connected to the full-duplex communication module, selects the optimal path or a combination of paths from multiple available communication paths for data transmission based on real-time status information of the communication link. Thanks to its multipath design, the full-duplex multipath communication system no longer relies on a single communication path. The path selection module monitors parameters such as signal strength, interference, and transmission rate of each path in real time and selects the optimal or multiple better paths for transmission. When a path is interfered with, fails, or its transmission quality degrades, the system can quickly switch to other available paths, avoiding the "all-or-nothing" problem of traditional single-path communication. In power grid and drone applications, full-duplex communication enables simultaneous transmission and reception, improving efficiency and meeting real-time requirements. Multi-path selection avoids reliance on a single path, ensuring stable and reliable transmission. Interference cancellation modules enhance anti-interference capabilities to adapt to complex environments. Data fragmentation transmission adapts to large data volumes. Encryption modules ensure security, and caching modules handle emergencies. Overall, these technologies improve the intelligence level and operational efficiency of power grid and drone communication.

[0029] Example 2: This example provides a full-duplex multipath communication method, including the following steps: Enable full-duplex communication mode: The communication node enables full-duplex communication, enabling simultaneous data transmission and reception; Real-time multi-path monitoring: Real-time monitoring of multiple available communication paths to obtain signal strength, interference value, and transmission rate parameters for each path; Dynamic path selection: Based on the monitored parameters, at least one target transmission path is determined from multiple communication paths through a preset optimization algorithm; Data fragmentation transmission: The data to be sent is fragmented according to the number and transmission capacity of the target transmission paths, and then sent synchronously on each target transmission path in full-duplex mode; Receive and merge processing: At the receiving end, the fragmented data transmitted from each target transmission path is received synchronously in full-duplex mode, and the fragmented data is merged to restore the complete data.

[0030] In power grid and drone applications, the full-duplex multipath communication method improves efficiency by enabling simultaneous transmission and reception, meeting real-time requirements. Multipath selection avoids dependence on a single path, ensuring stable and reliable transmission. The interference cancellation module enhances anti-interference capabilities to adapt to complex environments. Data fragmentation transmission adapts to large data volumes. The encryption module ensures security, and the caching module handles emergencies. Overall, it improves the intelligence level and operational efficiency of power grid and drone communication.

[0031] Example 3: This example provides several specific application cases of full-duplex multipath communication systems and methods, as follows: In an industrial automation control scenario, multiple full-duplex communication nodes are deployed at different devices on a production line. A multi-path selection module monitors in real time that the wireless communication path suffers from severe interference from the complex electromagnetic environment within the workshop, resulting in low signal strength and unstable transmission rates. In contrast, the wired communication path (using fiber optics) exhibits stable signal strength and high transmission rates. Based on a preset algorithm, the multi-path selection module prioritizes the fiber optic communication path for transmitting critical control commands. The control command data is broken down into small data packets and transmitted via the fiber optic path to the full-duplex communication node on the target device. Upon receiving the data packets, the node sorts and reassembles them according to identification information to reconstruct the complete control commands. This achieves precise industrial automation control, effectively avoiding errors or delays in control command transmission caused by wireless communication interference, and ensuring the efficient and stable operation of the production line.

[0032] In remote high-definition video transmission scenarios, full-duplex communication nodes are set up at both the video acquisition and receiving ends. The multi-path selection module detects that the signal strength, interference levels, and transmission rates of both the current 5G and WiFi 6 wireless communication paths meet certain conditions, with scores exceeding set thresholds. Therefore, the multi-path selection module decides to use these two wireless communication paths for parallel transmission. The high-definition video data is split into multiple small data packets, which are transmitted simultaneously via the 5G and WiFi 6 paths. At the receiving end, the data packets received from the two paths are merged, sorted according to their identification information, and reassembled to recover the high-definition video data. This multi-path parallel transmission method significantly improves the bandwidth of video transmission, enabling smooth playback of remote high-definition video and solving the problem that traditional single communication paths cannot meet the real-time transmission requirements of large amounts of high-definition video data.

[0033] In an intelligent transportation system, vehicles communicate with roadside infrastructure via full-duplex communication nodes. The interference cancellation module plays a crucial role; the analog domain self-interference cancellation unit uses hardware circuitry to couple and cancel the signals transmitted by the vehicle's full-duplex communication nodes, reducing interference to the received signals. However, a small amount of residual self-interference remains. Digital signal processing is then performed on the known transmitted and received signals to further eliminate this residual interference. Simultaneously, a strict data frame format, handshake protocol, and error checking and retransmission mechanism are defined. For example, when vehicles are traveling at high speeds, full-duplex communication nodes frequently exchange location information, road condition information, and other data. The data frame format ensures accurate data parsing, the handshake protocol ensures the establishment and maintenance of communication connections, and the error checking and retransmission mechanism promptly retransmits data when errors occur during data transmission, ensuring the accuracy and reliability of data communication in the intelligent transportation system and providing stable communication support for advanced functions such as autonomous driving.

[0034] In remote meter reading and dispatching of the power grid, multiple full-duplex communication nodes are distributed across various meter terminals and the dispatch center. The full-duplex communication module allows meter terminals to simultaneously send electricity consumption data and receive dispatch instructions, overcoming the asynchronous nature of data transmission and instruction reception in traditional half-duplex mode. The multi-path selection module monitors the status of each communication path in real time, including power line carrier paths and wireless communication paths. When interference occurs on the power line carrier path due to power grid load fluctuations, the module quickly switches to the wireless communication path, ensuring continuous uploading of electricity consumption data and timely issuance of dispatch instructions. The interference cancellation module effectively suppresses self-interference and external electromagnetic interference in the strong electromagnetic environment of the power grid through multiple processing methods in the analog, digital, and spatial domains, reducing data transmission errors. The control and coordination module manages all modules uniformly, dynamically adjusting the transmission parameters of each path during peak electricity consumption periods to cope with sudden surges in meter reading data. The system supports multiple communication protocols, adapting to different models of meter terminals and dispatching equipment, comprehensively improving the efficiency of remote meter reading and the timeliness of dispatch instruction execution, and ensuring the accuracy of power grid load management.

[0035] In the application of power grid drones for line inspection and fault diagnosis, the full-duplex communication node on the drone works in conjunction with the node at the ground control center to achieve synchronous transmission of inspection data and control commands. A multi-path selection module continuously monitors multiple wireless communication paths between the drone and the ground, including wireless links in different frequency bands. When the drone flies to mountainous areas or areas obstructed by buildings, and the signal of a certain frequency band is blocked, it quickly selects another unobstructed path to continue transmission. While capturing images of the power lines and collecting data such as equipment temperature, the drone can receive real-time control commands from the ground center, such as turning and zooming, avoiding inspection pauses caused by signal interruptions in traditional single-path communication. The interference cancellation module processes strong electromagnetic interference generated by the power grid lines, ensuring clear and accurate transmitted images and data, facilitating ground personnel's assessment of the line status. The data fragmentation transmission function breaks down large amounts of inspection data and sends them in parallel through multiple paths. The receiving end merges and processes the data to restore the complete data, solving the transmission delay problem when the data volume is too large. The control and coordination module ensures that all modules work together, improving the efficiency of drone inspections and the timeliness of fault diagnosis, ensuring the safe and stable operation of the power grid lines.
