Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic communication and integrated circuits, and specifically relates to a 5G signal transmission charging data line with anti-attenuation in a low-temperature environment. BACKGROUND

[0002] With the rapid development of 5G communication technology and the wide application of portable electronic devices, the performance stability of the embedded chip of the charging data line in a low-temperature environment has become a research hotspot. Especially in cold regions or extreme temperature conditions, the signal transmission efficiency and anti-attenuation ability of the chip will decrease significantly, resulting in reduced user experience and serious impact on the reliability of the device. Therefore, it is of great significance to develop a system that can effectively resist attenuation and ensure stable transmission of 5G signals in a low-temperature environment.

[0003] In the prior art, a patent with publication number CN106783653B proposes a chip internal temperature monitoring device based on a multi-chip stacking process. By stacking a thin film encapsulated NTC thermistor on a multi-chip packaging substrate, real-time monitoring of the internal temperature of the chip is achieved, and multiple temperature monitoring points can be flexibly configured to adapt to the needs of different working environments. However, this technical solution mainly focuses on the monitoring of the internal temperature of the chip and does not involve the optimization of the signal transmission performance of the chip in a low-temperature environment. In addition, its temperature monitoring function relies on an additional thermistor, which not only increases the design complexity and manufacturing cost of the chip, but also fails to directly solve the problem of signal attenuation caused by low temperature.

[0004] Another prior art, a patent with publication number CN118731658B, proposes a cold and hot impact test method for IC chips. By combining cold and hot interval impact testing with cold and hot rapid impact testing, the performance stability of IC chips in high and low temperature environments is evaluated, especially the ability to resist cold and hot temperature difference impact. However, this technical solution is limited to testing the performance of the chip under extreme temperature conditions and does not provide a specific solution to signal attenuation in a low-temperature environment. At the same time, this method focuses on testing rather than performance optimization in actual applications and cannot be directly applied to the low-temperature anti-attenuation design of the embedded chip of the charging data line.

[0005] The above problems show that the existing technical solutions have obvious deficiencies in the optimization of chip signal transmission performance in a low-temperature environment, especially in terms of anti-attenuation ability and stable transmission of 5G signals. In particular, in high-frequency application scenarios such as millimeter wave communication, the influence of low-temperature environment on signal transmission is more significant, further exacerbating the decrease in data transmission efficiency and the increase in delay.

DETAILED DESCRIPTION

[0024] The exemplary embodiments of the present disclosure will be described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to help understanding, and should be considered only as exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Also, in order to be clear and concise, the description in the following description omits the description of well-known functions and structures.

[0025] The specific embodiments are given below.

[0026] As Figures 1-4As shown, the charging data line body includes a line body 5 and a connector 51, the line body 5 is connected with the connector 51, and the line body 5 and the connector 51 can be integrally formed or connected by plugging; the inner side of the connector 51 is provided with an embedded chip 52, and the embedded chip 52 integrates an anti-attenuation system; The charging data line body is composed of a line body and a connector, and the two are connected together to form a complete charging data line. The line body is the main channel for data and power transmission, which is usually composed of multiple wires, insulation layer, shielding layer, etc., which can ensure the stable transmission of signals and current. The connector is the interface for connecting the data line with external devices (such as mobile phones, computers, etc.), responsible for data interaction and power supply; The inner side of the connector is provided with an embedded chip, which is the core component for realizing the anti-attenuation function of the charging data line in a low-temperature environment. It can use BQ25703, SMB1396, SC1933C, etc. Control chip supporting PD, QC, SCP, VOOC, etc. Fast charging protocol.

[0027] The anti-attenuation system of the embedded chip of the charging data line in a low-temperature environment according to the embodiment of the application, first of all, the core system of the application includes a signal compensation unit, a temperature regulation unit, a signal transmission optimization unit and a receiving end verification unit. These units work together to realize efficient transmission and stability of signals in a low-temperature environment. The signal compensation unit compensates the signal in a low-temperature environment in real time through dynamic millimeter wave signal enhancement technology, which is composed of a signal monitoring module and a signal enhancement module. In actual operation, the signal monitoring module will collect signal strength, signal-to-noise ratio and current temperature data in real time, and generate dynamic characteristic labels. These labels not only contain the basic parameters of the signal, but also record the dynamic change trend in the low-temperature environment, providing a basis for subsequent signal compensation. The signal enhancement module is based on dynamic millimeter wave signal enhancement technology, which compensates for signal attenuation caused by low temperature by adjusting millimeter wave transmission power and phase offset; For example, in extremely cold conditions, if the signal strength is detected to drop below a certain threshold, the signal enhancement module will automatically increase the millimeter wave transmission power and redistribute the signal resources according to the calculation result of the phase offset, so as to ensure the integrity of the signal transmission. In addition, the module can also dynamically adjust the compensation strategy according to the temperature data in the dynamic characteristic label to adapt to different low-temperature environments.

[0028] The design of the temperature regulation unit is based on the thermoelectric effect, which optimizes the working temperature of the chip through the joint action of the micro-heating module and the adaptive temperature control algorithm. A signal transmission guarantee system in low-temperature environment is constructed through a multi-unit cooperative mechanism. A signal compensation unit is based on dynamic millimeter wave signal enhancement technology, adopts a signal monitoring and enhancement dual-module architecture, and uses adaptive signal processing theory to achieve accurate compensation. The signal monitoring module collects key parameters such as signal strength and signal-to-noise ratio, and temperature data in real time according to the communication system performance evaluation theory, constructs a dynamic feature tag combined with a pattern recognition algorithm, accurately captures the dynamic change trend of the signal in the low-temperature environment by using data processing methods such as Kalman filtering, and provides reliable data support for compensation. The signal enhancement module dynamically adjusts the millimeter wave transmission power through an adaptive power control algorithm based on electromagnetic field theory and microwave engineering principles, adjusts the phase offset by using phase modulation and beamforming technology, compensates for the attenuation problems such as dielectric loss and signal scattering caused by low temperature, for example, when low temperature changes the air dielectric constant and causes signal attenuation, the module automatically increases the transmission power and optimizes the phase according to the temperature-attenuation model in the dynamic feature tag, and continuously optimizes the compensation strategy according to the environmental changes by using reinforcement learning algorithm. The temperature control unit is based on the principle of thermoelectric effect such as Peltier effect, realizes accurate temperature control through the micro-heating module, and uses intelligent control theories such as fuzzy control and PID control to dynamically adjust the working parameters of the micro-heating module according to the deviation between the actual chip temperature and the preset working temperature range, so as to ensure the stable operation of the chip in the low-temperature environment and effectively improve the signal transmission performance and reliability of the system in the low-temperature scene.

[0029] As shown in the accompanying drawings Figure 1 , the micro-heating module is constructed by using thermoelectric materials, which can convert electrical energy into heat energy to increase the surface temperature of the chip. In actual application, the temperature control unit first calculates the deviation between the current chip surface temperature and the target temperature through the temperature data in the dynamic feature tag; Then, the output power of the micro-heating module is adjusted by using the adaptive temperature control algorithm to maintain the chip temperature in the optimal working interval. The specific formula of the algorithm is: Wherein, represents the output power of the micro-heating module; represents the basic power; , , respectively represent the proportional, integral and differential coefficients; represents the temperature deviation; represents the time. Through this algorithm, the system can dynamically adjust the heating power according to the temperature change to ensure that the chip is always in the best working state; When the temperature fluctuation exceeds the set threshold, the system will also trigger a double-loop feedback mechanism to dynamically adjust the heating power and the heat dissipation rate, thereby further improving the accuracy of temperature control.

[0030] The signal transmission optimization unit utilizes the improved adaptive modulation and coding (AMC-Plus) algorithm to significantly improve the transmission efficiency of 5G signals in low-temperature conditions. Specifically, the unit first selects the optimal modulation mode and coding rate based on the signal-to-noise ratio (SNR) data in the dynamic characteristic tag. Then, it introduces a low-temperature characteristic weight factor to adjust the modulation parameters to adapt to the low-temperature environment. The calculation formula of the weight factor is: wherein, represents the low-temperature characteristic weight factor; and represent the weight coefficients of temperature and SNR, respectively; and represent the current temperature and the optimal working temperature, respectively; and SNR represent the current SNR and the SNR threshold, respectively. Through this formula, the system can consider the changes in temperature and SNR and dynamically adjust the modulation parameters to achieve more efficient signal transmission in low-temperature environments. In addition, the signal transmission optimization unit also uses dynamic spectrum allocation technology to preferentially allocate high-quality frequency band resources and adopts the hybrid automatic repeat request (HARQ) mechanism to ensure the reliability of data transmission. For example, in a low-temperature environment, if the signal quality of a certain frequency band is detected to be declining, the system will automatically switch to other high-quality frequency bands to avoid signal loss caused by frequency band interference. The signal transmission optimization unit is based on the theory of cognitive radio and the principle of digital communication to build a spectrum adaptive management system in low-temperature environments. The dynamic spectrum allocation technology uses a multi-dimensional spectrum sensing algorithm combined with a channel characteristic model in low-temperature environments (such as a model of the ionospheric disturbance caused by low temperatures affecting high-frequency signals). It realizes the optimal allocation of spectrum resources through a Markov decision process. The system monitors the signal strength, bit error rate, Doppler shift, and other parameters of each frequency band in real time and establishes an environment-spectrum mapping relationship using a deep reinforcement learning algorithm. When it detects that the signal quality of a certain frequency band has decreased below the threshold due to low temperatures, it automatically triggers the spectrum switching mechanism and preferentially allocates frequency bands that are less affected by low temperatures (such as the millimeter wave frequency band, which has relatively stable propagation loss in low-temperature dry environments). The Hybrid Automatic Repeat Request (HARQ) mechanism integrates Chase combining and incremental redundancy techniques. Based on advanced coding theories such as Low-Density Parity-Check (LDPC) codes and Turbo codes, it improves decoding success rate at the receiver through a soft information combining algorithm. The system dynamically adjusts the number of HARQ processes and redundancy versions according to channel fading characteristics in low-temperature environments. For example, it increases redundancy and extends the retransmission window under extremely cold conditions. Simultaneously, it employs Adaptive Modulation and Coding (AMC) technology to select the optimal modulation order and coding rate based on real-time channel quality, achieving a balance between transmission reliability and spectral efficiency. Through collaborative optimization at the physical and link layers, it effectively resists adverse effects such as multipath fading and phase noise in low-temperature environments, ensuring the continuity and integrity of data transmission.

[0031] The receiver verification unit performs integrity verification on the received signal through a multi-level error correction mechanism and recovers the original data, as shown in the attached figure. Figure 1 As shown, the unit includes a signal verification module and a data reconstruction module. The signal verification module performs integrity verification on the received signal through a multi-level error correction mechanism and marks erroneous data blocks. For example, when there are errors in the received data packets, the signal verification module will analyze and mark the erroneous parts layer by layer according to the preset error correction rules, and the data reconstruction module will reorder and merge the block data according to the verification results to restore the original signal format. In practical applications, this process can effectively avoid signal loss or damage caused by low temperature environment, thereby ensuring high reliability of data transmission.

[0032] To further illustrate the actual operating principle and process of this invention, the following description is in conjunction with the appendix. Figure 2 The specific implementation steps of a 5G signal transmission charging data cable with low temperature resistance are described in detail. First, the system collects signal strength, signal-to-noise ratio and temperature data in real time through the signal monitoring module and generates dynamic feature tags. These tags contain key parameter information of the current environment, providing a basis for the operation of subsequent units. Next, the signal compensation unit performs real-time compensation for signals in low-temperature environments based on dynamic millimeter-wave signal enhancement technology; For example, in extremely cold conditions, if the signal strength is detected to drop below a certain threshold, the signal compensation unit will automatically adjust the millimeter wave transmission power and phase offset to compensate for the signal attenuation caused by low temperature, while the temperature regulation unit optimizes the working temperature of the chip through the micro-heating module and the adaptive temperature control algorithm. Specifically, the system first calculates the deviation between the current chip surface temperature and the target temperature, and adjusts the output power of the micro-heating module using the adaptive temperature control algorithm to maintain the chip temperature in the optimal working interval. When the temperature fluctuation exceeds the set threshold, the system will trigger a double-loop feedback mechanism to dynamically adjust the heating power and heat dissipation rate, thereby further improving the accuracy of temperature control. Subsequently, the signal transmission optimization unit uses the improved adaptive modulation and coding (AMC-Plus) algorithm to improve the transmission efficiency of 5G signals in low temperature conditions. The unit first selects the optimal modulation method and coding rate according to the signal-to-noise ratio data in the dynamic characteristic label, and introduces a weight factor based on low temperature characteristics to adjust the modulation parameters to adapt to the low temperature environment. In addition, the system also uses dynamic spectrum allocation technology to preferentially allocate high-quality frequency band resources, and uses the hybrid automatic repeat request (HARQ) mechanism to ensure the reliability of data transmission. Finally, the receiving end verification unit uses a multi-level error correction mechanism to verify the integrity of the received signal and recover the original data. For example, when there are errors in the received data packet, the signal verification module will analyze and mark the error part layer by layer according to the preset error correction rules, and then the data recombination module will reorder and merge the block data according to the verification result to recover the original signal format.

[0033] In actual application scenarios, the technical scheme of the present application can be widely applied to 5G communication equipment in extremely cold areas, such as polar research stations or high-altitude areas. Due to the extremely low environmental temperature, traditional 5G signal transmission equipment often has problems such as severe signal attenuation and low transmission efficiency. After using the system and method provided by the present application, the equipment can maintain stable signal transmission performance in low temperature environment, while significantly reducing energy consumption and maintenance cost. In addition, the present application can also be applied to vehicle charging equipment, especially in cold weather, the embedded chip of the vehicle charging data line needs to operate efficiently in low temperature environment. Through the signal compensation, temperature regulation and transmission optimization functions of the present system, the vehicle charging equipment can realize stable data transmission and fast charging in extreme conditions.

[0034] In summary, through the signal monitoring module of the signal compensation unit, real-time acquisition of signal strength, signal-to-noise ratio and temperature data is realized, combined with the signal enhancement module based on dynamic millimeter wave signal enhancement technology, which can dynamically adjust the millimeter wave transmission power and phase offset, accurately compensate the signal attenuation caused by low temperature, significantly improve the stability and reliability of the signal in low temperature environment, and effectively avoid the data transmission interruption or error caused by signal attenuation.

[0035] Through the temperature regulation unit, a micro-heating module is designed based on the thermoelectric effect, combined with an adaptive temperature control algorithm, which can calculate the deviation from the target temperature according to the real-time temperature data of the chip, and dynamically adjust through proportional, integral and differential coefficients, so that the chip temperature is stably maintained in the optimal working interval. When the temperature fluctuation exceeds the set threshold, a double-cycle feedback mechanism is triggered to dynamically adjust the heating power and heat dissipation rate, providing a stable working environment for the chip and reducing the performance degradation problem caused by low temperature, prolonging the service life of the chip.

[0036] Through the signal transmission optimization unit, an improved adaptive modulation and coding (AMC-Plus) algorithm is used to select the optimal modulation method and coding rate according to the signal-to-noise ratio data in the dynamic characteristic label, and a weight factor based on low temperature characteristics is introduced to adjust the modulation parameters. Combined with dynamic spectrum allocation technology, high-quality frequency band resources are preferentially allocated, and a hybrid automatic repeat request (HARQ) mechanism is used, which greatly improves the transmission efficiency and reliability of 5G signals in low temperature conditions, effectively reduces the data transmission delay and error rate.

[0037] The signal verification module of the receiving end verification unit verifies the integrity of the received signal through a multi-stage error correction mechanism, marking the error data block, and the data reorganization module reorders and merges the block data according to the verification result to restore the original signal format, ensuring the completeness and accuracy of the received data in low temperature environment, and ensuring the quality of data transmission, providing stable and reliable data transmission services for users.

Compared with a single technical means, this cooperative working mode can more comprehensively and effectively cope with the influence of low temperature environment on the performance of the embedded chip of the charging data line, greatly improving the overall performance and adaptability of the system.
