Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations. The following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figure 1 , the present invention provides a power wireless high-speed communication device, including a communication module, a signal processing module, a power management module, and a heat dissipation module.

[0020] Regarding the communication module: In terms of communication, the present invention is equipped with an advanced antenna system and a radio frequency front-end module. The antenna system adopts a multi-band and multi-polarization design scheme, which can cover a wide frequency range and effectively cope with complex electromagnetic environments. The radio frequency front-end module integrates components such as high-gain amplifiers, low-noise amplifiers, and filters to ensure the transmission quality and anti-interference ability of signals. To further improve communication efficiency, the present invention also introduces intelligent beamforming technology in the antenna system, which can dynamically adjust the antenna beam direction according to the position of the receiving end to achieve directional transmission, thereby reducing energy loss and increasing the communication distance.

[0021] Among them, the antenna system is the core component for realizing long-distance wireless communication. The antenna system of the present invention adopts a multi-band high-gain antenna, which can work efficiently in multiple frequency ranges. To improve the gain and directivity of the antenna, the present invention also introduces phased array antenna technology. The phased array antenna realizes electronic scanning and focusing of the beam by precisely controlling the phase difference of each antenna element, and can flexibly adjust the signal transmission and reception directions without moving the physical antenna. This feature enables the antenna system to quickly lock on to the target node in a complex power environment, reduce signal attenuation, and improve communication efficiency. The phased array antenna also has multiple input multiple output (MIMO) functions. By respectively configuring multiple antennas at the transmitting end and the receiving end, it can simultaneously transmit multiple data streams in the same frequency band, thereby greatly improving the spectrum utilization rate and transmission rate. The working frequency band covers 2.4 GHz - 52.6 GHz. It has strong anti-interference ability and can maintain stable communication performance in complex electromagnetic environments. Combined with beamforming technology, it can further optimize the signal transmission path to ensure the efficient transmission of data in complex environments.

[0022] By adopting a multi-band high-gain antenna system combined with a linear array antenna technology, the present invention is able to achieve optimal transmission performance in different frequency ranges. The design of the multi-band antenna can not only adapt to different environmental conditions but also effectively avoid the congestion problem of a single band. The system supports dynamic spectrum allocation and can adjust the working frequency band in real time according to the actual communication requirements to ensure the smoothness of the communication link.

[0023] The antenna system also adopts a multi-band tunable technology, supporting a wide spectrum range from low frequency to high frequency. By integrating multiple antenna units with different frequencies, the device can automatically select the optimal working frequency band in different working environments, avoiding communication interruptions caused by frequency band conflicts or interference. The antenna system is built-in with an intelligent frequency band switching mechanism, which can dynamically adjust the working frequency according to the real-time channel conditions to ensure that the communication link is always in the best state.

[0024] The design of the antenna body adopts new materials and technologies to ensure stable performance in a complex electromagnetic environment. The outer shell of the antenna is made of lightweight and high-strength composite materials, such as carbon fiber composite materials or carbon fiber silicone composite materials, with good wind resistance and corrosion resistance characteristics. It not only ensures the mechanical strength of the antenna but also reduces the overall weight, facilitating installation and maintenance. The antenna internally integrates an intelligent tuning circuit, which can automatically adjust the frequency and gain according to different communication environments to ensure the best communication effect. The outer shell of the antenna is made of special electromagnetic shielding materials, which can effectively isolate external electromagnetic interference and protect the internal circuit from being affected. The heat dissipation design of the antenna system has also been carefully optimized. Through efficient heat sinks and air convection channels, it is ensured that the antenna will not overheat during long-term operation, extending its service life.

[0025] To adapt to different application scenarios, the antenna system also provides a variety of installation methods, including wall-mounted, pole-mounted, and embedded, etc. So that whether in power facilities such as substations, transmission towers, or distribution rooms, users can choose the most suitable installation method according to actual needs to ensure the best coverage range and communication effect of the antenna. The antenna system is equipped with remote monitoring and diagnosis functions. Users can monitor the working status of the antenna in real time through a network platform, discover and solve potential problems in a timely manner, and ensure the continuity and stability of communication.

[0026] The RF front-end module integrates components such as high-gain amplifiers, low-noise amplifiers, and filters to ensure the transmission quality and anti-interference ability of signals. To further improve communication efficiency, the device also introduces intelligent beamforming technology, which can dynamically adjust the antenna beam direction according to the position of the receiving end to achieve directional transmission, thereby reducing energy loss and increasing the communication distance. It can effectively suppress interference signals in a complex electromagnetic environment. By introducing a duplexer and filters, the present invention can separate useful signals from interference signals to ensure the signal quality received by the receiving end. The RF front-end is also equipped with an automatic gain control (AGC) module, which can automatically adjust the receiving sensitivity in the case of large signal strength variations to avoid transmission errors caused by overly strong or weak signals.

[0027] To further improve communication efficiency, the present invention introduces adaptive modulation and demodulation technology. This technology can automatically select the most suitable modulation method according to the channel quality, thereby maximizing the transmission rate while ensuring the reliability of data transmission. For example, in the case of good channel conditions, the system can select a high-order modulation method (such as 64QAM) to increase data throughput; while in the case of poor channel conditions, it automatically switches to a low-order modulation method (such as QPSK) to ensure the stability of data transmission.

[0028] The present invention also has strong anti-interference ability. By integrating an adaptive interference suppression algorithm, the present invention can monitor the changes in the surrounding electromagnetic environment in real time and dynamically adjust communication parameters according to the characteristics of interference sources. For example, when strong co-frequency interference is detected, the system will automatically switch to a standby frequency band or reduce the transmission power to reduce the impact of interference on communication. The adaptive interference suppression algorithm can also identify and filter out false interference signals to avoid unnecessary frequency band switching and ensure the stability and continuity of the communication link.

[0029] To further enhance the stability of the communication device, the present invention also introduces a distributed redundancy design. By deploying multiple communication nodes in the network, the present invention can automatically switch to other available nodes when a certain node fails to ensure the continuity of the communication link. The distributed redundancy design not only improves the fault tolerance of the system but also effectively disperses the risk of single-point failures, enhancing the robustness of the entire communication network. Experimental results show that after adopting the distributed redundancy design, the mean time between failures (MTBF) of the communication system has increased by nearly 50%, greatly improving the reliability of power communication.

[0030] Regarding the signal processing module: The signal processing and enhancement module is the core part of the power wireless high-speed communication device, responsible for operations such as decoding, filtering, amplifying, and error correction of the signals received by the antenna, ensuring the integrity and reliability of the signals. This module includes heterogeneous computing units, integrating digital signal processing (DSP) cores and software-defined radio (SDR) architectures, with a computing power of ≥12 TOPS; a hybrid automatic repeat request system, adopting LDPC coding and incremental redundancy mechanisms; an adaptive equalizer, with a convergence speed of ≤10 μs and a non-linear distortion suppression of ≥30 dB; this signal processing module uses a modulation method combining OPSK and QAM, switching between QPSK / 16QAM / 64QAM / 256QAM according to the signal-to-noise ratio; the signal processing module of the present invention adopts advanced digital signal processing (DSP) technology and software-defined radio (SDR) architectures, capable of flexibly coping with various complex communication scenarios and providing efficient and stable signal processing capabilities.

[0031] At the signal receiving end, the module integrates a high-sensitivity low-noise amplifier (LNA), which can amplify weak radio frequency signals to a level suitable for subsequent processing while minimizing noise interference to the greatest extent. The LNA design adopts low-temperature drift technology and an adaptive gain control algorithm to ensure stable amplification performance at different temperatures and signal intensities. The module is also equipped with multi-stage filters, which can effectively remove out-of-band interference and spurious signals to ensure the purity of the received signals.

[0032] To improve the anti-interference ability of the signals, the signal processing and enhancement module introduces adaptive equalization technology. This technology dynamically adjusts the equalization parameters by analyzing the channel characteristics in real time, compensating for the frequency response distortion and phase distortion in the channel, thereby restoring the integrity of the original signals. The adaptive equalizer can quickly adapt to the changing channel environment, ensuring high-quality signal transmission even in a power environment with severe multipath effects.

[0033] At the signal transmitting end, the module adopts an efficient power amplifier (PA) and linearization technology to ensure that the power and spectral characteristics of the transmitted signals meet the standard requirements. The PA design adopts broadband matching technology and an efficient heat dissipation structure, capable of maintaining a stable working state during high-power output and avoiding performance degradation caused by overheating or overloading. The module also integrates a predistortion correction circuit, which can effectively eliminate non-linear distortion and improve the quality of the transmitted signals.

[0034] To cope with complex power environments, the signal processing and enhancement module also has powerful error correction coding capabilities. This module supports a variety of forward error correction (FEC) algorithms, such as convolutional codes, Turbo codes, and LDPC codes, etc., and can automatically detect and correct errors during signal transmission to ensure the accuracy and integrity of data. The module is also equipped with an automatic repeat request (ARQ) mechanism. When the receiving end detects packet loss or damage, it will automatically request the sending end to retransmit, further improving the reliability of communication.

[0035] To improve the flexibility and scalability of the system, the signal processing and enhancement module adopts a software-defined radio (SDR) architecture. The SDR architecture allows users to change parameters such as communication protocols, modulation methods, and frequency bands through software configuration without having to replace hardware devices. This design not only simplifies system maintenance and upgrades but also facilitates future function expansion. The module also supports a variety of communication standards, such as Wi-Fi, Bluetooth, TCP / IP, MQTT, LoRa, Zigbee, etc., and can meet the requirements of different application scenarios.

[0036] Regarding the power management module: Power management and energy-saving design are important components of the power wireless high-speed communication device, aiming to ensure stable power supply during long-term operation of the device, while minimizing energy consumption as much as possible and extending battery life. This module adopts an advanced power management module, combined with intelligent power consumption control technology and energy recovery mechanism, to achieve efficient and reliable energy management.

[0037] This invention adopts an efficient DC-DC converter and battery management system, which can extend battery life while ensuring stable power supply. The power management module integrates multiple power input interfaces, supports multiple power supply methods such as alternating current, direct current, and solar energy, to ensure stable power supply for the device in different environments. The module is equipped with an efficient switching power converter inside, which can achieve high-efficiency energy conversion within a wide voltage range to ensure the stability and accuracy of the output voltage. The module also has multiple protection functions such as overvoltage, overcurrent, and short circuit, which can effectively prevent power failures from damaging the device.

[0038] To reduce energy consumption, the power management module adopts intelligent power consumption control technology. This technology dynamically adjusts the power consumption of each module by monitoring the working state of the device in real time. For example, the present invention is provided with a multi-source input interface, supporting the switching between mains power / photovoltaic / thermoelectric power generation, with an interruption time < 0.5 ms; a dynamic voltage regulation system, with an adjustable output voltage of 3.3 - 48 V and a mode switching time ≤ 10 μs; a thermoelectric - radio frequency hybrid energy recovery system, with a recovery efficiency ≥ 15%. In the low-load or standby state, the module automatically reduces the frequency and voltage of the processor to reduce unnecessary power consumption; while in the high-load or communication-busy state, the module quickly improves performance to ensure smooth communication. The module also supports the sleep mode. When the device has no communication tasks for a long time, it automatically enters the low-power sleep state to further save power.

[0039] To further improve energy efficiency, the power management module introduces an energy recovery mechanism. This mechanism converts the waste heat and surplus electricity generated during the operation of the device into usable electrical energy for other modules. For example, the heat sink in the module can be equipped with a small thermoelectric generator to generate electrical energy using the temperature difference; while the wireless charging coil can recover part of the electromagnetic energy during signal reception to supplement the battery power. This energy recovery mechanism not only extends the service life of the battery but also reduces the dependence on external power supplies.

[0040] To adapt to different application scenarios, the power management module also provides a variety of energy-saving strategies. For example, in remote areas or places with insufficient power supply, the module can preferentially use solar energy or other renewable energy sources to reduce the dependence on mains power; while in urban or industrial environments, the module can choose a more efficient AC power supply method to ensure the continuous and stable operation of the device. The module also supports remote monitoring and management functions. Users can view the power status of the device in real time through a network platform, adjust the energy-saving strategies, and ensure the best energy consumption performance.

[0041] Power management and energy-saving design not only provide a reliable energy guarantee for the power wireless high-speed communication device but also significantly reduce the energy consumption of the device, extend the battery life, and improve the overall performance and reliability of the system through intelligent power consumption control and energy recovery mechanisms.

[0042] Heat dissipation module: Since the power wireless high-speed communication device generates a lot of heat during operation, the performance of the heat dissipation system is crucial. The device adopts a heat dissipation solution that combines liquid cooling and air cooling, which can maintain good heat dissipation in high temperature environments. The heat dissipation system includes liquid-cooled heat sinks and air-cooled heat sinks, which are in direct contact with the RF front-end power amplifier; a temperature sensor array distributed on the surface of key heat-generating components; a liquid-cooled pipe directly connected to the liquid-cooled heat sink; a centrifugal fan directly connected to the air-cooled heat sink, which is graded and adjusted according to the heat load; the heat dissipation module predicts the temperature change trend through a thermodynamic model, and works in conjunction with the power management module to control the power supply parameters.

[0043] The temperature sensing array formed by multiple temperature sensors monitors the temperature of each component in real time, and automatically adjusts the fan speed and coolant flow rate according to the temperature change to ensure that the system is always within the optimal operating temperature range. The internal temperature is monitored in real time and the heat dissipation strategy is automatically adjusted to ensure that the device can operate normally in a high temperature environment. The shell material of the present invention is an aluminum alloy with good thermal conductivity and corrosion resistance, which not only helps to dissipate heat, but also effectively resists erosion from the external environment.

[0044] Enable high-speed wireless communication: The present invention adopts the new generation of 5G millimeter wave communication technology, which can achieve ultra-high-speed data transmission in high-frequency bands (such as 28GHz and 39GHz). Compared with traditional microwave bands, millimeter wave bands have larger bandwidth resources and can support higher transmission rates. However, millimeter wave communication also faces challenges such as fast signal attenuation and poor penetration. To this end, the present invention introduces beamforming technology, which accurately controls the signal transmission direction through an intelligent antenna array, effectively enhancing the coverage and penetration of the signal. After using beamforming technology, the signal transmission distance increased by about 30%, and the transmission rate increased by nearly two times.

[0045] In order to cope with complex electromagnetic environments, the present invention also integrates multiple-input multiple-output (MIMO) technology. MIMO technology can transmit multiple data streams simultaneously in the same frequency band by configuring multiple antennas at the transmitting end and the receiving end, thereby greatly improving spectrum utilization and transmission rate. MIMO technology also has strong anti-interference capabilities and can maintain stable communication performance in complex electromagnetic environments. Combined with beamforming technology, the MIMO system can further optimize the signal transmission path and ensure efficient data transmission in complex environments.

[0046] In addition to technological innovations at the hardware level, the present invention has also been deeply optimized at the software level. By introducing advanced channel coding technologies such as Polar Code and Low-Density Parity-Check (LDPC) code, among which, the Polar Code encoder has a code length of 1024 bits and an adjustable code rate of 0.5 - 0.9; the LDPC decoder adopts a layered belief propagation algorithm; and a Hybrid Automatic Repeat reQuest (HARQ) controller. The present invention can significantly improve the transmission rate while ensuring the reliability of data transmission. As a new type of coding technology, the Polar Code can achieve transmission performance close to the Shannon limit in a high-noise environment, and is particularly suitable for long-distance and low-power communication scenarios in the power system. The LDPC code, with its excellent error correction ability and low computational complexity, has become an ideal choice for high-speed wireless communication.

[0047] The present invention also supports carrier aggregation technology, which can integrate the bandwidth resources of multiple frequency bands to form a wider virtual channel, thereby further improving the transmission rate. Carrier aggregation technology can not only make full use of existing spectrum resources, but also flexibly adjust bandwidth allocation according to actual needs to ensure the best communication performance in different application scenarios. Experimental data shows that after using carrier aggregation technology, the transmission rate has increased by nearly three times, fully meeting the requirements of the smart grid for high-speed communication.

[0048] Enhancing communication stability: The present invention adopts an advanced radio frequency front-end design, which can effectively suppress interference signals in a complex electromagnetic environment. By introducing a duplexer and a filter, it supports 28 GHz / 39 GHz communication; the carrier aggregation unit has a maximum aggregation bandwidth of 60 MHz. The present invention can separate useful signals from interference signals to ensure the signal quality received by the receiving end. The radio frequency front-end is also equipped with an Automatic Gain Control (AGC) module, which can automatically adjust the receiving sensitivity in the case of large signal strength variations to avoid transmission errors caused by over-strong or over-weak signals. After using this radio frequency front-end design, the signal error rate has been reduced by about 40%, and the communication stability has been significantly improved.

[0049] The present invention also has a strong anti-interference ability. By integrating an adaptive interference suppression algorithm, the present invention can monitor the changes in the surrounding electromagnetic environment in real time and dynamically adjust communication parameters according to the characteristics of interference sources. For example, when strong co-frequency interference is detected, the system will automatically switch to a standby frequency band or reduce the transmission power to reduce the impact of interference on communication. The adaptive interference suppression algorithm can also identify and filter out false interference signals to avoid unnecessary frequency band switching and ensure the stability and continuity of the communication link.

[0050] To further enhance the stability of the communication device, the present invention also introduces a distributed redundancy design. By deploying multiple communication nodes in the network, the present invention can automatically switch to other available nodes when a certain node fails, ensuring the continuity of the communication link. The distributed redundancy design not only improves the fault tolerance of the system but also effectively disperses the risk of single-point failures, enhancing the robustness of the entire communication network. Experimental results show that after adopting the distributed redundancy design, the mean time between failures (MTBF) of the communication system has increased by nearly 50%, greatly improving the reliability of power communication.

[0051] The present invention also has a perfect fault detection and self-recovery function. Through the built-in diagnostic module, the present invention can monitor the working status of each hardware component in real time and issue an alarm and take corresponding repair measures in a timely manner when an abnormal situation is detected. For example, when a certain antenna fails, the system will automatically switch to the standby antenna to ensure that the communication is not affected. The self-recovery function can also automatically restore to the working state before the failure after the system restarts, avoiding the trouble of manual intervention and further improving the stability of the communication device.

[0052] Through various technological innovations, the present invention not only improves the efficiency and speed of power communication but also significantly enhances the stability of the communication device, providing a strong technical guarantee for the intelligent development of the power system.
