DETAILED DESCRIPTION

[0017] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The implementation of the objectives, functional features and advantages of the present invention will be further described in conjunction with the embodiments and with reference to the accompanying drawings.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Reference Figure 1 , is a method for connecting a vehicle-mounted central control screen and a central control box in an embodiment of the present invention, comprising: S1: Based on the preset operation process of the vehicle, detect the data link between the vehicle central control screen and the central control box; S2: Determine whether the data link has timed out; S3: If yes, then obtain the electromagnetic interference source of the vehicle, identify the interference parameters of the interference signal according to the electromagnetic interference source, associate the perception data with the status data of the vehicle-mounted central control screen according to the pre-integrated electromagnetic wave sensor, and generate the corresponding electromagnetic interference trend, wherein the electromagnetic interference source specifically includes a high-frequency radiation source, a medium-frequency interference source and a low-frequency interference source, the interference parameters specifically include interference frequency, interference intensity and interference propagation path, and the status data specifically includes touch response and image rendering quality; S4: Determine whether the electromagnetic interference trend has the same electromagnetic waveform; S5: If it exists, based on the preset vehicle-mounted sensor network, the electromagnetic wave transmission path is monitored, and according to the electromagnetic wave transmission path, the position of the electromagnetic interference source is tracked and located in real time, and according to the position of the electromagnetic interference source, the signal transmission mode between the vehicle-mounted central control screen and the central control box is dynamically adjusted, wherein the signal transmission mode specifically includes modulation method, bandwidth selection and signal recovery.

[0020] In this embodiment, the system detects the data link between the vehicle's central control screen and the central control box based on the vehicle's pre-set data operation process, and then the system determines whether the data link has timed out to execute the corresponding steps; for example, when the system determines that the data link transmission between the vehicle's central control screen and the central control box has not timed out, the system will consider that the data link is in a normal transmission state, and the system's real-time communication and signal stability are good. The system will continue to monitor the health of the link, including indicators such as signal strength, transmission delay and error rate, and regularly check the signal quality between the central control screen and the central control box to ensure that there is no potential interference or weak signal area, and at the same time evaluate the potential risk of electromagnetic interference in the vehicle environment, especially in different driving modes or vehicle speeds. By real-time monitoring of the vehicle's electromagnetic environment, possible interference trends are predicted. In high-risk areas (such as high-speed driving and areas near strong electromagnetic sources), the system maintains sensitivity to electromagnetic interference, promptly identifies signs of signal quality degradation, and ensures that the data stream priority processing mechanism is still effective under normal circumstances. The system automatically adjusts bandwidth allocation and transmission mode according to the priority of the data stream to optimize the overall performance of the data link. For example, when the system determines that the data link transmission between the vehicle's central control screen and the central control box has timed out, the system will consider the data link to be abnormal and unable to transmit data normally. The system will obtain the vehicle's electromagnetic interference source through the pre-deployed electromagnetic interference sensor. The electromagnetic interference source specifically includes high-frequency radiation sources and medium-frequency interference. Sources and low-frequency interference sources. According to different electromagnetic interference sources, the interference parameters of the interference signal are identified. The interference parameters specifically include interference frequency, interference intensity and interference propagation path. According to the pre-integrated electromagnetic wave sensor, the perception data is associated with the status data of the vehicle's central control screen. The status data specifically includes touch response and image rendering quality, and the corresponding electromagnetic interference trend is generated; by deploying electromagnetic interference sensors, the system can obtain electromagnetic interference sources inside and outside the vehicle in real time, including high-frequency, medium-frequency and low-frequency interference sources, which enables the system to accurately identify and locate interference sources, provide data support for subsequent interference source isolation and optimization, and avoid the impact of electromagnetic interference on the vehicle's central control system. At the same time, by identifying the frequency, intensity and The system can analyze the type and impact range of electromagnetic interference based on these interference parameters, and can determine the current interference status and predict possible problems (such as touch failure or image quality degradation) so as to make targeted adjustments. The system also associates the electromagnetic interference perception data with the status data of the central control screen (such as touch response and image rendering quality) to evaluate the impact of interference on the vehicle-mounted central control screen in real time. By generating electromagnetic interference trends, the system can dynamically adjust the signal transmission mode, reduce data link timeouts and signal loss, ensure stable operation of the vehicle-mounted system, and ultimately improve user experience and vehicle performance. The system then determines whether the electromagnetic interference trend has the same electromagnetic waveform to execute the corresponding steps.For example, when the system determines that the electromagnetic interference trend does not have the same electromagnetic waveform, the system will think that the current interference signal may be new, changing or irregular, which means that the interference source may be changing, and the system has not yet preset this interference mode. The system will further evaluate and confirm the electromagnetic interference source, and it is necessary to obtain more detailed interference data through electromagnetic sensors, rescan the spectrum, and further analyze whether the interference source has changed (such as frequency fluctuations, intensity changes, etc.). At the same time, if the interference source is more sudden or cannot be immediately identified, the system should initiate temporary mitigation measures, such as reducing the power of signal transmission, or through other redundant paths (such as adding communication channels, adjusting data The system can avoid serious impact on the work of the central control system by monitoring the changes in the electromagnetic environment, especially after discovering new interference sources, collecting and feeding back interference data in real time, and ensuring that the system can adapt to complex electromagnetic environments and avoid long-term signal problems by continuously updating interference models and adjusting optimization strategies. For example, when the system determines that the electromagnetic interference trend has the same electromagnetic waveform, the system will think that the interference source has not changed. The system will monitor the electromagnetic wave transmission path based on the pre-set vehicle-mounted sensor network, and track and locate the electromagnetic interference source in real time according to these electromagnetic wave transmission paths. According to the different electromagnetic interference source locations, the vehicle-mounted central control will be dynamically adjusted. The signal transmission mode of the vehicle central control screen and the central control box includes modulation mode, bandwidth selection and signal recovery. The system tracks the electromagnetic wave transmission path in real time based on the vehicle-mounted sensor network and can accurately locate the location of the electromagnetic interference source. This provides accurate data support for further analysis of the impact of the interference source, helping the system to quickly identify and isolate the interference source to prevent it from having a continuous impact on the stability of the vehicle-mounted central control system. At the same time, when the system identifies that the interference source has not changed, it can dynamically adjust the signal transmission mode of the vehicle-mounted central control screen and the central control box according to the location information of the interference source, including modulation mode, bandwidth selection and signal recovery strategy. This automated adjustment can adapt to the intensity and Features ensure the stability of data transmission, avoid problems such as touch failure, image jitter or signal loss, and through dynamic adjustment based on the location of the interference source, the system can intelligently respond to different electromagnetic interference scenarios, optimize the signal transmission path, and improve the response speed and image quality of the central control screen. Users can enjoy a smoother and more stable operation experience during use, reduce the performance degradation of the central control screen caused by interference, and thus enhance the overall user experience. Dynamic adjustment of the signal transmission mode can not only optimize the data link, but also improve the anti-interference ability according to real-time interference changes, which makes the vehicle system more resilient and adaptive in the electromagnetic interference environment, reducing the negative impact of interference on system performance. ;

[0021] In this embodiment, the step S3 of obtaining the electromagnetic interference source of the vehicle further includes: S31: identifying different types of electromagnetic interference sources based on a preset spectrum analyzer, wherein the electromagnetic interference sources specifically include radio frequency interference, radiation interference, and conducted interference; S32: Determine whether the electromagnetic interference source reaches a preset abnormal signal strength; S33: If so, extract the frequency characteristics of the electromagnetic interference source, obtain the interference source type corresponding to the electromagnetic interference source according to the frequency characteristics, and calculate the interference range of the electromagnetic interference source according to the interference source type, wherein the frequency characteristics specifically include the modulation mode and duration, and the interference source type specifically includes a constant signal and a pulse signal.

[0022] In this embodiment, the system identifies different types of electromagnetic interference sources based on a pre-set spectrum analyzer. The electromagnetic interference sources specifically include radio frequency interference, radiation interference and conducted interference. The system then determines whether these electromagnetic interference sources reach a pre-set abnormal signal strength to execute corresponding steps. For example, when the system determines that a certain electromagnetic interference source does not reach the pre-set abnormal signal strength, the system will believe that although the current electromagnetic interference exists, the intensity is not enough to pose a threat to the normal operation of the vehicle-mounted central control system. The system will not immediately adjust the signal transmission mode, maintain the current data link configuration, avoid unnecessary intervention and resource consumption, and continuously monitor the electromagnetic interference source and record its intensity change trend. Although the current interference intensity has not reached an abnormal level, the system can use it as an early warning signal for potential problems. By regularly evaluating the intensity changes of the electromagnetic interference source, the system can predict whether the interference source will intensify at some point in the future, be prepared to respond, and maintain flexibility. When the intensity of the electromagnetic interference source changes, it can respond quickly according to the change. If the interference intensity gradually increases and exceeds the threshold, the system should be able to adjust the signal transmission mode in time, improve the filter performance, and even enable emergency measures such as redundant communication channels. For example, when the system determines that a certain electromagnetic interference source has reached a preset abnormal signal strength, the system will consider that the current electromagnetic interference poses a threat to the operation of the vehicle's central control. The system will extract the frequency characteristics of the electromagnetic interference source. The frequency characteristics specifically include modulation mode and duration. According to different frequency characteristics, the interference source type corresponding to the electromagnetic interference source is obtained. The interference source type specifically includes constant signal and pulse signal. Based on these interference source types, the electromagnetic interference source is calculated. interference range; by extracting the frequency characteristics of the electromagnetic interference source (such as modulation mode and duration), the system can accurately distinguish whether the interference source is a constant signal or a pulse signal, which enables the system to take tailored intervention measures for different types of interference sources and improve the accuracy and efficiency of coping with electromagnetic interference. At the same time, based on the identification of the interference source type (constant signal or pulse signal) and the calculation of the interference range, the system can predict the impact range of the interference source on the vehicle's central control system. Through this prediction, the system can adjust the signal transmission path, optimize the bandwidth selection and modulation method in advance to ensure that the communication between the central control screen and the central control box is not affected. By analyzing the characteristics of the electromagnetic interference source, the system can dynamically adjust the response strategy. For example, the impact of pulse signals and constant signals on signal transmission is different. The system can optimize the signal recovery mechanism and adjust the signal transmission mode in a targeted manner. This dynamic adjustment can enhance the system's adaptability and anti-interference ability to different types of electromagnetic interference and improve the stability of the system.

[0023] It should be noted that the frequency characteristics of the electromagnetic interference source are extracted, and the interference source type corresponding to the electromagnetic interference source is obtained according to the frequency characteristics. According to the interference source type, the interference range of the electromagnetic interference source is calculated. The specific examples are as follows: Assume that inside a vehicle, the system detects a high-frequency pulse signal, which comes from the pulse emission of the vehicle-mounted radar system. This radar system is used to monitor obstacles ahead or realize autonomous driving functions. Radar signals usually have a short pulse duration (for example, microseconds) and a high emission frequency (such as 24 GHz). When this radar signal interferes with the signal link of the vehicle-mounted central control screen, it may cause image jitter or touch failure. Step 1: Identify the pulse signal characteristics. The system detects the pulse signal emitted by the radar system through a spectrum analyzer. The frequency is 24 GHz. The duration of the pulse signal is very short, about 1 microsecond, and it belongs to the high-frequency short pulse type. The system also detects that the intensity of the pulse signal has obvious fluctuations near the vehicle-mounted central control device. Step 2: Determine the type of interference source. Based on the extracted frequency characteristics and signal duration, the system identifies the interference source as a pulse signal, the main source of which is the vehicle-mounted radar. Step 3: Calculate the interference range. Since the pulse signal is characterized by instantaneous appearance and rapid attenuation, the interference range mainly depends on the signal propagation path, frequency and signal transmission power. Assuming that the transmission power of the vehicle radar system is 10W (watts), and the radar signal will be affected by the reflection and shielding effect of the metal structure of the vehicle body when propagating in the vehicle, the propagation attenuation is calculated according to the path loss model. According to the free space path loss formula, the attenuation of the pulse signal can be estimated: ; d is the distance the signal travels (in meters), f is the frequency of the signal (in Hertz), K is a constant (related to the environment, equipment, etc., usually assumed to be a constant); Assuming that the signal propagation distance in the vehicle environment is 1 to 3 meters, and the frequency of the radar signal is 24 GHz, substitute the formula to calculate the attenuation value; according to the estimation results, the radar signal has a small attenuation within a range of 3 meters, but beyond this range, the impact of the signal weakens rapidly; because the signal is of pulse nature, its interference mainly affects the devices in the vehicle that are close to the signal link, such as the vehicle-mounted central control screen, the vehicle-mounted navigation system, and electronic equipment at close range; Step 4: Take countermeasures. Within the interference range of the detected pulse signal, the vehicle system will automatically adjust the signal processing method, such as strengthening filtering, adjusting bandwidth or changing frequency modulation, to reduce the impact of radar signals on the vehicle central control system. The system may also dynamically adjust the radar working mode, such as changing the transmission power or frequency of the radar pulse, to reduce interference to the vehicle central control equipment. To sum up, through the above examples, the vehicle system can accurately identify and analyze the characteristics and propagation range of the pulse signal interference source, and then make targeted signal processing and protection measures to ensure that the vehicle central control system can still operate stably in a complex electromagnetic environment; this precise interference range calculation and adjustment strategy helps to improve the anti-interference ability of vehicle electronic equipment and reduce the occurrence of problems such as image jitter, touch failure and signal loss.

[0024] In this embodiment, after step S3 of identifying interference parameters of the interference signal, the following step is further included: S301: Based on the pre-collected electromagnetic environment changes, identifying the mutual interference effect between the electromagnetic interference sources, wherein the mutual interference effect specifically includes interference superposition and spectrum overlap; S302: Determine whether the mutual interference has the same influence on the signal; S303: If not, divide the interference priority corresponding to the interactive interference effect, and obtain the link status between the vehicle-mounted central control screen and the central control box according to the interference priority. According to the link status, dynamically adjust the preset communication signal waveform, wherein the link status specifically includes connection interruption, data loss and signal quality degradation, and the communication signal waveform specifically includes frequency hopping, spread spectrum and orthogonal waveform.

[0025] In this embodiment, the system identifies the mutual interference between electromagnetic interference sources based on the pre-collected electromagnetic environment change data, and the mutual interference specifically includes interference superposition and spectrum overlap, and then the system determines whether the degree of influence of these mutual interference effects on the signal is the same, so as to execute the corresponding steps; for example, when the system determines that the mutual interference between the electromagnetic interference sources has the same degree of influence on the signal, the system will consider that the signal interference generated by these interference sources has similar characteristics, such as similar frequency range, similar interference intensity, and similar propagation path, and the system will evaluate the interaction between multiple interference sources and compare their effects on the signal quality of the vehicle-mounted central control screen (such as touch response, The evaluation indicators include the interference intensity of the signal, the range of the interference frequency, the propagation path of the interference source, and their impact on the delay or packet loss of the data link. At the same time, the filter configuration is automatically adjusted to enhance the filtering effect on specific frequency bands and reduce the impact of interference signals. For example, the band-stop filter is added to the overlapping frequency band to filter out unnecessary frequency components. For serious spectrum overlap, the system can change the modulation mode of the signal (such as from QAM modulation to more anti-interference PSK modulation) to enhance the anti-interference ability of the signal. According to the characteristics of the electromagnetic interference source, the bandwidth of the signal is adjusted to limit the impact of the frequency range of the interference source and reduce the occurrence of cross interference. For example, reduce the use of broadband spectrum and use narrower frequency bands to reduce overlap with other spectrums. In severe interference situations, the system can enable redundant data links, such as backing up data transmission paths through multi-path communication or using other communication protocols (such as Wi-Fi, Bluetooth, etc.) to ensure the stability of the central control screen. For example, when the system determines that the degree of influence of the mutual interference between electromagnetic interference sources on the signal is different, the system will consider that the signal interference generated by these interference sources does not have similar characteristics. The system will divide the interference priorities corresponding to these mutual interference effects, and obtain the link status between the vehicle-mounted central control screen and the central control box according to different interference priorities. The link status specifically includes connection interruption, data loss and signal quality degradation, and dynamically adjusts the pre-set communication signal waveform. The communication signal waveform specifically includes frequency hopping, spread spectrum and orthogonal waveform; the system can more accurately judge which interference sources have a greater impact on the communication between the vehicle-mounted central control screen and the central control box, and which have a smaller impact by identifying the different degrees of impact of the interaction between the interference sources on the signal. In this way, the system can take more targeted optimization measures, thereby effectively reducing unnecessary interference processing and avoiding waste of resources. At the same time, according to the link status (such as connection interruption, data loss and signal quality degradation) and interference priority, the communication signal waveform (such as frequency hopping, spread spectrum and orthogonal waveform) is dynamically adjusted.These adjustments can effectively deal with different types of interference and improve the stability and reliability of communication links. For example, frequency hopping technology can effectively avoid fixed-frequency interference, while spread spectrum technology can increase the signal's anti-interference ability. By real-time monitoring and interference priority division, the system can more flexibly adapt to changes in different electromagnetic environments. When the impact of certain interference sources is large, the system can give priority to processing these interferences and ensure the transmission of high-priority signals, thereby ensuring the stable operation of the vehicle's central control system in a complex electromagnetic environment. By obtaining link status information (such as connection interruption, data loss, and signal quality degradation), it can promptly detect and respond to communication problems and take appropriate measures (such as adjusting the signal waveform) to restore the stability of the link. This mechanism helps the system adjust communication strategies more intelligently to ensure unimpeded data transmission between the vehicle's central control screen and the central control box.

[0026] In this embodiment, the step S5 of tracking and locating the electromagnetic interference source in real time according to the electromagnetic wave transmission path further includes: S51: Based on a preset sensor in the vehicle, collecting a time difference when the sensor receives the electromagnetic interference wave, and calculating the position information of the electromagnetic interference source according to the time difference; S52: Determine whether the position information matches the arrival angle of the interference source signal; S53: If not, then measure the electromagnetic signal attenuation of the electromagnetic interference source, infer the direction to be corrected of the position information based on the electromagnetic signal attenuation, and generate the distance to be corrected corresponding to the position information through a preset signal attenuation characteristic.

[0027] In this embodiment, the system collects the time difference of the electromagnetic interference wave received by the sensor based on the pre-installed sensor in the vehicle, calculates the location information of the electromagnetic interference source according to the different time differences, and then determines whether the location information matches the arrival angle of the interference source signal to execute the corresponding steps; for example, when the system determines that the location information of the electromagnetic interference source can match the arrival angle of the interference source signal, the system will believe that it can successfully identify and locate the location of the electromagnetic interference source, and the interference signal of the interference source is consistent with the expected transmission path and propagation angle, and the system will confirm whether the interference source continues to exist and continue to affect the communication link of the vehicle-mounted central control system, which means that the system has It can accurately locate the interference source and carry out subsequent interference protection in a targeted manner. At the same time, it can avoid the influence of the interference source by adjusting the signal transmission path or modifying the signal waveform. For example, the system can avoid the strong interference area of ​​the interference source by changing the frequency, bandwidth or modulation method of the communication signal to ensure stable signal transmission, and dynamically adjust the communication strategy based on the positioning information, such as changing the data transmission method between the vehicle-mounted central control screen and the central control box, or switching between different frequency bands, such as selecting a frequency band that is not affected by interference for data transmission to avoid signal transmission in the frequency band where the interference source is located; for example, when the system determines that the location information of the electromagnetic interference source cannot match the arrival angle of the interference source signal At this time, the system will think that it cannot accurately identify the location of the electromagnetic interference source. The system will measure the electromagnetic signal attenuation of the electromagnetic interference source, and based on the attenuation of these electromagnetic signals, infer the direction of the position information to be corrected, and generate the distance to be corrected corresponding to the position information through the pre-set signal attenuation characteristics; the system can further infer the position correction direction of the interference source by measuring the attenuation of the electromagnetic signal, so as to accurately adjust the positioning of the interference source. Even if the initial positioning information is inaccurate, the signal attenuation provides additional correction clues to help the system accurately locate the interference source, which helps the system avoid inaccurate interference response caused by misjudgment of the interference source position. At the same time, electromagnetic signal attenuation is used as Based on the correction positioning, the system can adapt to the complexity of different environments and interference sources. Different types of electromagnetic interference sources may present different attenuation characteristics under different conditions. The correction direction is inferred based on these attenuation characteristics, so that the system can stably identify and correct the position of the interference source in various electromagnetic environments, improve the system's adaptability and anti-interference ability to complex environments, and by combining the electromagnetic signal attenuation characteristics, the system can more accurately infer the actual location of the interference source, avoid misjudging an unrelated signal source as an interference source, thereby avoiding unnecessary signal adjustments and waste of resources. In addition, accurate positioning helps to take corresponding interference mitigation measures more efficiently and improve system efficiency.

[0028] It should be noted that the electromagnetic signal attenuation of the electromagnetic interference source is measured, and the direction to be corrected of the position information is inferred based on the electromagnetic signal attenuation. The distance to be corrected corresponding to the position information is generated through a preset signal attenuation characteristic. The specific examples are as follows: Assume that a vehicle is traveling on a highway, and the onboard central control system is transmitting data with the central control box through wireless communication. However, during the transmission process, due to electromagnetic interference, the data link is unstable, resulting in touch failure and image jitter. To solve this problem, the system relies on the preset electromagnetic wave detector in the vehicle to monitor the signal strength and attenuation of the electromagnetic interference source in real time, so as to determine the location of the interference source and make corrections. The system operation steps are as follows: 1. First, the signal attenuation of the electromagnetic interference source is measured. The electromagnetic wave detectors in the vehicle are set in the front, rear, left and right directions of the vehicle. Assume that the system receives the signal from the electromagnetic interference source (such as the vehicle-mounted Wi-Fi module) and records the signal strength data at different locations. The following are the measurement results of the sensor: Front sensor (about 400 meters from the interference source): the received signal strength is 120 units, and the theoretical attenuation value is 100 units (that is, ideally, the signal attenuation at 400 meters should be 100 units); Left sensor (about 250 meters from the interference source): received signal strength is 140 units, and the theoretical attenuation value is 50 units; Rear sensor (about 350 meters from the interference source): the received signal strength is 180 units, and the theoretical attenuation value is 70 units; Right sensor (about 500 meters from the interference source): received signal strength is 90 units, and the theoretical attenuation value is 120 units; 2. Infer the location information of the interference source. According to the signal strength of the sensor, the approximate location of the interference source can be preliminarily analyzed: The signal strength of the rear sensor (180 units) is significantly higher than that of sensors in other directions, which indicates that the interference source may be located at the rear of the vehicle, and the signal strength is higher near the rear of the vehicle, which may be due to signal reflection or multipath propagation; The signal strength of the left sensor (140 units) is higher than that of the front and right sensors, indicating that the interference source is closer to the left side of the car; The signal strength (90 units) received by the right sensor is the weakest, suggesting that the interference source is far away from the right side of the vehicle; Therefore, the system infers that the interference source should be located behind the left side of the vehicle, about 320 meters away, and may be related to the reflection effect of other vehicles or road objects; 3. Estimate the direction of the position information to be corrected. The system further estimates the correction direction based on the attenuation data and signal strength. Since the signal strength of the rear sensor is obviously higher, the system estimates that the interference source should be closer to the rear of the vehicle, and the signal of the left sensor is also stronger, indicating that the interference source is biased towards the left rear. Therefore, the system believes that the interference source should be located slightly to the left of the rear of the vehicle, rather than directly behind the vehicle; this assumption will be corrected to: slightly to the left of the rear of the vehicle, about 320 meters away; 4. Correct the distance to be corrected for the location information. The system further estimates the actual distance of the interference source based on the signal attenuation characteristics. Assuming that the attenuation model is known, the system calculates: The distance sensor behind the vehicle is about 300 meters, and the signal strength is 180 units, while the theoretical value should be 70 units; The left side is 250 meters away from the sensor, the signal strength is 140 units, and the theoretical attenuation is 50 units; Based on this information, the system infers that the interference source is on the left side behind the vehicle, about 320 meters away from the rear sensor. At this time, the system sets the distance to be corrected to 320 meters and updates the vehicle's central control system. 5. Adjust the signal transmission mode. According to the corrected interference source location, the system will dynamically adjust the signal transmission mode between the vehicle-mounted central control screen and the central control box; for example: The system will adjust the communication protocol, enhance the stability of the signal, and select appropriate modulation methods, such as spread spectrum modulation, to avoid electromagnetic interference; Adjust the bandwidth and frequency range of the signal to avoid the frequency of the interference source and ensure the reliability of the communication signal; According to the specific location of the interference source, timely adjust the image rendering quality or touch response parameters of the central control screen to reduce the impact of interference on the system; 6. Final effect: Through these adjustments, the system can effectively reduce image jitter and touch failure caused by electromagnetic interference, improve the stability and reliability of the vehicle's central control system, and enable the driver to enjoy a smoother operating experience during driving; To summarize, in the above examples, by measuring and analyzing the signal attenuation of the electromagnetic interference source, the system can accurately infer the location of the interference source and effectively correct the impact of the interference on the vehicle's central control screen by adjusting the signal transmission mode; this method combines sensor data and signal attenuation characteristics to not only improve the positioning accuracy of the interference source, but also optimize the signal stability of the vehicle system, effectively improving the user experience and avoiding problems such as data loss and touch failure caused by electromagnetic interference.

[0029] In this embodiment, the step S2 of determining whether the data link has timed out further includes: S21: based on preset signal capture conditions, collecting signal waveform data of the data link, wherein the signal capture conditions specifically include signal transition, rising edge and falling edge; S22: Determine whether abnormal distortion is detected in the signal waveform data; S23: If yes, a preset oscilloscope is used to obtain the echo effect of the signal waveform data, and based on the echo effect, a reflection phenomenon of the data link during the signal transmission process is generated, and the overlap degree of the reflection phenomenon is compared with the original signal.

[0030] In this embodiment, the system collects signal waveform data of the data link based on pre-set signal capture conditions, which specifically include signal transitions, rising edges, and falling edges, and then the system determines whether these signal waveform data detect distortion anomalies to execute corresponding steps; for example, when the system determines that the signal waveform data of the data link does not detect distortion anomalies, the system will consider that the current signal link is in normal working condition and is not affected by electromagnetic interference or other abnormal phenomena, and the system will keep the current communication signal settings and modes unchanged, because the signal waveform data does not detect distortion, indicating that the signal transmission is stable and the data transmission quality meets the requirements, and at the same time, real-time monitoring is performed through pre-set signal capture conditions (such as signal transitions, rising edges, and falling edges) to ensure that the link quality is not affected by sudden electromagnetic interference or other influences, which is to prevent signal attenuation or other potential problems in subsequent processes, and when the signal waveform data is normal, the computing resources and network bandwidth are preferentially allocated to other tasks, or other parts of the system that need to be processed are optimized to improve the overall performance of the vehicle central control system; for example, when the system determines that the signal waveform data of the data link detects distortion anomalies, the system will consider that the signal link is in normal working condition and is not affected by electromagnetic interference or other abnormal phenomena, and the system will consider that the signal waveform data of the data link detects distortion anomalies ... Because the current signal link is abnormal, the system will use a pre-set oscilloscope to obtain the echo effect of the signal waveform data, and generate the reflection phenomenon of the data link during the signal transmission process according to different echo effects, and compare the overlap degree of the reflection phenomenon with the original signal; by comparing the echo effect and the reflection phenomenon, the system can identify and locate the reflection source that may cause signal distortion or distortion, which helps the system to determine whether there is physical interference, such as mismatched impedance or connector problems, and then accurately determine the possible fault points in the signal transmission path, thereby achieving precise fault diagnosis. At the same time, by comparing the echo effect and the reflection phenomenon, the system can identify and locate the reflection source that may cause signal distortion or distortion, which helps the system to determine whether there is physical interference, such as mismatched impedance or connector problems, and then accurately determine the possible fault points in the signal transmission path, thereby achieving precise fault diagnosis, and automatically adjust the transmission parameters of the data link according to the overlap degree of the reflection phenomenon, such as adjusting the modulation mode of the signal, the transmission bandwidth or using adaptive coding to reduce signal distortion and reduce the impact of interference. Through intelligent adjustment, the system can respond to changes in the electromagnetic environment in real time to ensure the stability and quality of signal transmission under different interference conditions.

[0031] It should be noted that a preset oscilloscope is used to obtain the echo effect of the signal waveform data, and based on the echo effect, a reflection phenomenon of the data link during signal transmission is generated, and the overlap degree of the reflection phenomenon and the original signal is compared. The specific examples are as follows: Assume that there is a vehicle-mounted central control system that is responsible for displaying the vehicle's navigation information in real time and controlling various functions on the touch screen. Recently, drivers have reported that they often experience image delays and touch failures during use. The system detects that the signal waveform data is distorted, so it starts the preset oscilloscope to capture the echo effect and further analyze the source of the signal reflection phenomenon. 1. Signal acquisition and echo effect capture. The signal of the vehicle central control system is transmitted from the central control box to the central control screen through a data link (for example, through an HDMI or LVDS interface). Suppose that during the connection process, due to some physical or electronic component problems (such as loose connection lines, oxidation of connectors, or poor contact), the signal transmission is reflected; Oscilloscope capture: The system uses an oscilloscope to monitor the signal waveform in real time; when the oscilloscope displays the waveform, it is found that the peaks and troughs of the signal have changed compared to the original signal, and there is a significant delay; Delay of echo signal: Through the time axis of the oscilloscope, the system found that the reflected signal lagged behind the original signal by about 15 microseconds; this is because part of the signal was reflected back when it passed through the connection point and was not fully transmitted to the receiving end; 2. Generate a reflection phenomenon model. The system makes a detailed comparison between the echo signal and the original signal. The echo signal and the original signal have some deviation in waveform, showing the characteristics of reflection. The amplitude of the reflected signal is weaker than the original signal, indicating that the reflected signal has not been fully restored. Reflection path inference: The system infers the source of the reflected signal by analyzing the echo. In this case, the signal reflection mainly occurs at the connection line interface between the vehicle's central control box and the central control screen. It may be due to loose interfaces or poor contact, which causes the signal to be reflected during transmission. 3. Compare the overlap between the reflection phenomenon and the original signal. Signal overlap analysis: The oscilloscope shows that the waveform overlap between the echo signal and the original signal is 80%, which means that the waveforms of the reflected signal and the original signal are highly similar and the delay time is obvious; Signal attenuation analysis: Through comparison, the system also found that the amplitude of the echo signal was attenuated by about 20% compared with the original signal, indicating that the reflected signal was attenuated before returning to the receiving end; this may be due to some impedance mismatch in the reflection path, resulting in energy loss; 4. Problem identification and solutions, Problem identification: Based on the analysis of the echo signal, the system found that the main reason for the reflection was the impedance mismatch or poor contact at the interface between the central control box and the central control screen. This reflection interference caused signal distortion, which in turn affected the image rendering quality and touch response of the central control screen. The solution is: Check the connection: First check and make sure the connection cable interface between the central control box and the central control screen is stable and not loose; Optimize impedance matching: If the problem persists, the system will recommend using impedance-matched cables to ensure that the impedance of the signal transmission path matches the signal source and receiver to reduce the generation of reflected signals. Enhanced shielding measures: Add a shielding layer near the signal line to reduce external electromagnetic interference; Signal conditioning: The system can also mitigate interference by dynamically adjusting the signal transmission mode, such as using frequency hopping or spread spectrum technology to make the signal more robust during transmission and reduce the impact of reflected signals; To summarize, in the above examples, by using an oscilloscope to collect the echo effect of the signal and comparing it with the original signal, the system can accurately identify the reflection phenomenon in signal transmission; through waveform overlap and signal attenuation analysis, the system can not only confirm the source of the reflection problem, but also take targeted measures to repair it; this method can effectively improve the signal quality of the vehicle-mounted central control system and avoid problems such as image jitter, touch failure and signal loss caused by reflection.

[0032] In this embodiment, the step S4 of determining whether the electromagnetic interference trend has the same electromagnetic waveform further includes: S41: Based on a preset signal filter, identifying a bandwidth range of the signal filter; S42: Determine whether a preset number of signal frequency bands are detected within the bandwidth range; S43: If yes, dynamically adjust the configuration parameters of the signal filter according to the electromagnetic waveform, and adaptively adjust the gain effect of the signal filter according to the interference intensity of the electromagnetic interference trend, wherein the configuration parameters specifically include bandwidth frequency and cutoff frequency.

[0033] In this embodiment, the system identifies the bandwidth range of the signal filter based on the signal filter pre-set in the vehicle, and then the system determines whether the bandwidth range detects a preset number of signal frequency bands to execute the corresponding steps; for example, when the system determines that the bandwidth range of the signal filter does not detect a preset number of signal frequency bands, the system will believe that the bandwidth of the signal filter may not be sufficient to cover all expected signal frequency bands, or there is a signal source that is not within the expected frequency range. The system can adjust the bandwidth range of the filter to cover all possible signal frequency bands. Depending on the operating frequency of the vehicle-mounted system and possible interference sources, increasing the bandwidth may help ensure that signals in all key frequency bands are captured by the filter. and processing, thereby improving signal clarity and communication stability, and re-evaluating the set frequency band range to ensure that the set frequency band is consistent with the interference source frequency band in the actual working environment. If necessary, the surrounding environment can be scanned by a spectrum analyzer to identify potential signal sources and update the filter's frequency band settings to ensure that all interference sources are processed. In addition, multi-channel signal processing technology is introduced to increase the filter's capture capability by processing signals in multiple frequency bands at the same time, such as using broadband filters or adaptive filtering technology, so that the system can more flexibly adjust the frequency band range and signal processing strategy; for example, when the system determines that the bandwidth range of the signal filter detects a pre-set number of signal frequency bands, the system will It is believed that the bandwidth of the signal filter can cover all expected signal frequency bands. The system will dynamically adjust the configuration parameters of the signal filter according to different electromagnetic waveforms. The configuration parameters specifically include bandwidth frequency and cutoff frequency. According to the interference intensity of the electromagnetic interference trend, the gain effect of the signal filter is adaptively adjusted; the system can optimize the signal transmission quality in real time in a complex electromagnetic environment, reduce signal loss or distortion, and ensure the communication stability between the vehicle-mounted central control screen and the central control box by adaptively adjusting the gain effect of the signal filter according to the interference intensity of the electromagnetic interference trend. This dynamic adjustment mechanism can effectively respond to environmental changes, keep the signal clear and low noise, and dynamically adjust the bandwidth frequency and cutoff frequency. For different electromagnetic waveforms, the most suitable signal processing method is automatically selected. For signals with high electromagnetic interference intensity, the system can enhance the signal filtering capability, suppress unnecessary noise signals, and give priority to the transmission of useful signals. This adaptability enables the system to maintain high efficiency in high-interference environments and significantly improves anti-interference capabilities. By adaptively adjusting the gain effect of the filter, the system can flexibly adjust the working state of the filter according to the real-time electromagnetic interference intensity, avoiding unnecessary signal enhancement or excessive filtering, thereby saving energy and avoiding excessive signal processing and waste of computing resources. The system can maximize the optimization of energy consumption and computing resource usage while meeting signal quality.

[0034] In this embodiment, based on the preset operation process of the vehicle, the step S1 of detecting the data link between the vehicle-mounted central control screen and the central control box also includes: S11: Based on the data packet capturer preset by the vehicle, collecting the communication data between the vehicle-mounted central control screen and the central control box, wherein the communication data specifically includes packet loss rate, delay, transmission rate and signal strength; S12: Determine whether the communication data reaches a preset data quality; S13: If not, the communication data is quality scored, and the data stream priority of the vehicle is dynamically adjusted according to the quality score, wherein the data stream priority specifically includes emergency safety data stream, critical operation data stream and non-safety but critical auxiliary data stream.

[0035] In this embodiment, the system collects the communication data between the vehicle-mounted central control screen and the central control box based on the data packet capturer pre-installed in the vehicle. The communication data specifically includes packet loss rate, delay, transmission rate and signal strength, and then the system determines whether these communication data reach the preset data quality to execute the corresponding steps; for example, when the system determines that the communication data can reach the preset data quality, the system will consider that the communication link between the vehicle-mounted central control screen and the central control box is stable and reliable, and can effectively transmit information without obvious data loss, excessive delay or signal attenuation problems. The system will continue to use the current communication configuration to ensure that the vehicle-mounted central control system works efficiently and stably in the current state. In this case, the system does not need to make additional adjustments and continues to maintain the existing bandwidth, transmission protocol and signal adjustment settings. At the same time, according to good data transmission conditions, Prioritize other system functions that require quick response (such as the in-vehicle entertainment system, navigation system, or safety warning system). This ensures that the system provides faster response and more efficient services while ensuring stable communication, and reduces the continuous monitoring of network status and the complexity of troubleshooting. This facilitates the daily operation and maintenance of the vehicle and fault detection, so that related maintenance work can focus on other possible problems rather than communication link problems. For example, when the system determines that the communication data cannot reach the preset data quality, the system will consider that the communication link between the in-vehicle central control screen and the central control box is severely jittered. The system will score the quality of the communication data and dynamically adjust the vehicle's data flow priority based on different quality scores. The data flow priority specifically includes emergency safety data flow, critical operation data flow, and non-safety but critical auxiliary data flow.The system dynamically adjusts the priority of data streams to ensure that emergency safety data streams (such as emergency braking signals, collision detection, vehicle positioning information, etc.) can be transmitted first when the communication link is jittery or the quality is poor. This ensures that the safety of the vehicle is not affected when the signal is unstable, minimizes safety hazards, and improves the reliability and security of driving. At the same time, by dynamically adjusting the priority of different types of data streams, the system can reasonably allocate communication resources in the case of limited bandwidth or poor signal quality, and give priority to the transmission of key operation data streams (such as vehicle speed, engine status, feedback from driving assistance systems, etc.), ensuring the real-time nature of the vehicle's core control operations and avoiding communication problems. The system can appropriately reduce the priority of non-safety but critical auxiliary data streams (such as in-vehicle entertainment systems, non-critical driving data, etc.) or delay transmission when the communication quality is poor, thereby ensuring that the overall stability and reliability of the system will not be affected in a harsh communication environment. Through such priority adjustments, the system can optimize under limited resources and reduce the risk of information loss. By giving priority to high-priority data streams, the system can avoid failures or interruptions caused by poor communication quality. The normal transmission of emergency data and critical operation data can ensure that vehicle functions are not affected and avoid major problems or failures caused by untimely or lost information transmission. ;

[0036] It should be noted that the communication data is scored for quality, and the data flow priority of the vehicle is dynamically adjusted according to the quality score. The specific examples are as follows: Assume that a car is driving on a highway. The communication link between the onboard central control screen and the central control box is subject to different interferences and quality fluctuations. The vehicle's network environment is affected by external factors (such as buildings, tunnels, or bad weather), resulting in poor communication quality. The system monitors the quality of the link in real time, scores it, and dynamically adjusts the data flow priority based on the score. Communication data parameters monitored by the system: Packet loss rate: 28% (high). Due to signal interference, the packet loss rate is high, affecting the stability of data transmission. Latency: 220ms (high), the transmission delay increases, which may cause delays in the transmission of real-time operation instructions; Transmission rate: 1.5Mbps (low). Due to poor signal quality, the data transmission rate decreases, affecting the real-time transmission capability of large amounts of data. Signal strength: Weak. Due to external interference, the received signal strength is weak, affecting the stability and reliability of communication; Systematic quality score calculation: Based on these parameters, the system uses a preset scoring algorithm to derive a comprehensive quality score. For example, assume that the scoring rules of the system are as follows: 5 points will be deducted for every 10% packet loss rate, 3 points for every 100ms delay, 2 points for every 2Mbps transmission rate, and 4 points for every 10% drop in signal strength. Calculate the score: Packet loss rate (28%): 28%>10%, deduct 5×2=10 points; Delay (220ms): 220ms>100ms, deduct 3×2=6 points; Transmission rate (1.5Mbps): 1.5Mbps<2Mbps, deduct 2×2=4 points; Signal strength: Weak (assuming a 20% drop), deduct 4×2=8 points; Total score = 100-10-6-4-8 = 72 points, indicating that the quality of the communication link is poor; Adjust the priority of data streams based on the score: 1. High-priority data streams: Emergency safety data streams, such as emergency brake signals, collision warnings, vehicle stability control data, etc. These data are directly related to vehicle safety and must be transmitted in real time and stably. If these data streams are delayed or lost, they may directly lead to traffic accidents. Priority processing: Regardless of the current communication quality, the system will ensure the transmission of these urgent safety data; even if the link quality is poor, the system will do its best to ensure that these data are transmitted first, and can even ensure that these data are not affected by means such as compressing data and reducing redundant data; Use redundant data transmission technology to ensure that secure data can be transmitted through other backup paths even if packet loss occurs; enhance the transmission priority of these data streams so that they can still arrive in time despite signal interference; 2. Medium priority data stream: Regarding key operational data streams, such as vehicle speed, engine status, navigation data, etc., these data are not as urgent as safety data, but are still critical to the driving experience and operation; Priority processing: If the system evaluates that the current link quality is poor and urgent safety data has been given priority, these operation data flows will be processed as medium priority data flows; For some data that is not sensitive to time delay (such as vehicle speed), the transmission can be slightly delayed, allowing a delay of several hundred milliseconds; for data that is updated frequently (such as engine status), the data update frequency can be reduced to reduce data transmission pressure; 3. Low-priority data streams: non-security but critical auxiliary data streams, such as in-vehicle entertainment systems, in-vehicle Wi-Fi, entertainment video streams, in-vehicle audio controls, etc. These data do not pose a threat to safety and vehicle operation, but are important to the passenger experience; Priority processing: In the case of poor network quality, these low-priority data streams can be completely postponed for transmission, or part of the content can be discarded when the network is unstable without affecting driving safety; Some low-priority data packets (such as music or videos being played) may be completely discarded, which will not affect the normal operation of the vehicle under poor network conditions; if there is severe signal interference, the video playback may be completely stopped to prioritize the transmission of basic information; The final effect is that the system first ensures that the emergency safety data stream can be guaranteed under poor communication conditions to avoid safety hazards. By adjusting the transmission priority of key operation data streams, it ensures that the vehicle can operate normally in harsh environments. Although some non-emergency data may be delayed, and although entertainment and non-safety data streams are postponed or discarded, passengers can still accept this adjustment without affecting the overall driving safety. To sum up, in the above examples, through this quality scoring and data stream priority dynamic adjustment mechanism, the system can effectively allocate resources when there is large signal interference, ensure that the most critical data is transmitted first, and minimize the impact of poor communication quality on vehicle safety and driving experience.

[0037] Reference Figure 2 , is a connection system between a vehicle-mounted central control screen and a central control box in one embodiment of the present invention, comprising: The detection module 10 is used to detect the data link between the vehicle-mounted central control screen and the central control box based on the preset operation process of the vehicle; A judging module 20, configured to judge whether the data link has timed out; The execution module 30 is used for obtaining the electromagnetic interference source of the vehicle, identifying the interference parameters of the interference signal according to the electromagnetic interference source, and correlating the perception data with the status data of the vehicle-mounted central control screen according to the pre-integrated electromagnetic wave sensor to generate a corresponding electromagnetic interference trend, wherein the electromagnetic interference source specifically includes a high-frequency radiation source, a medium-frequency interference source and a low-frequency interference source, the interference parameters specifically include interference frequency, interference intensity and interference propagation path, and the status data specifically includes touch response and image rendering quality; A second judgment module 40 is used to judge whether the electromagnetic interference trend has the same electromagnetic waveform; The second execution module 50 is used to monitor the electromagnetic wave transmission path, if any, based on a preset vehicle-mounted sensor network, track and locate the position of the electromagnetic interference source in real time according to the electromagnetic wave transmission path, and dynamically adjust the signal transmission mode between the vehicle-mounted central control screen and the central control box according to the position of the electromagnetic interference source, wherein the signal transmission mode specifically includes modulation method, bandwidth selection and signal recovery.

[0038] In this embodiment, the detection module 10 detects the data link between the vehicle-mounted central control screen and the central control box based on the data operation process pre-set by the vehicle, and then the judgment module 20 judges whether the data link transmission has timed out to execute the corresponding steps; for example, when the system determines that the data link transmission between the vehicle-mounted central control screen and the central control box has not timed out, the system will consider that the data link is in a normal transmission state, and the real-time communication and signal stability of the system are good. The system will continue to monitor the health status of the link, including indicators such as signal strength, transmission delay and error rate, and regularly check the signal quality between the central control screen and the central control box to ensure that there is no potential interference or weak signal area, and at the same time evaluate the potential risk of electromagnetic interference in the vehicle environment, especially in different driving modes. By real-time monitoring of the vehicle's electromagnetic environment, possible interference trends are predicted in high-risk areas (such as high-speed driving and areas near strong electromagnetic sources), sensitivity to electromagnetic interference is maintained, signs of signal quality degradation are promptly identified, and the priority processing mechanism of the data stream is ensured to be effective under normal circumstances. The bandwidth allocation and transmission mode are automatically adjusted according to the priority of the data stream to optimize the overall performance of the data link. For example, when the system determines that the data link transmission between the vehicle's central control screen and the central control box has timed out, the execution module 30 will consider that the data link is abnormal and data cannot be transmitted normally. The system will obtain the vehicle's electromagnetic interference source through the pre-deployed electromagnetic interference sensor. The electromagnetic interference source specifically includes high-frequency radiation sources, medium The system can identify the interference parameters of the interference signal according to the different electromagnetic interference sources. The interference parameters include interference frequency, interference intensity and interference propagation path. According to the pre-integrated electromagnetic wave sensor, the perception data is associated with the status data of the vehicle central control screen. The status data includes touch response and image rendering quality, and the corresponding electromagnetic interference trend is generated. By deploying electromagnetic interference sensors, the system can obtain electromagnetic interference sources inside and outside the vehicle in real time, including high-frequency, medium-frequency and low-frequency interference sources. This enables the system to accurately identify and locate interference sources, provide data support for subsequent interference source isolation and optimization, and avoid the impact of electromagnetic interference on the vehicle central control system. At the same time, by identifying the frequency, intensity and transmission of interference signals, the system can also identify the interference source. The system can analyze the type and impact range of electromagnetic interference based on these interference parameters, and can determine the current interference status and predict possible problems (such as touch failure or image quality degradation) so as to make targeted adjustments. The system also associates the electromagnetic interference perception data with the status data of the central control screen (such as touch response and image rendering quality) to evaluate the impact of interference on the vehicle-mounted central control screen in real time. By generating an electromagnetic interference trend, the system can dynamically adjust the signal transmission mode, reduce data link timeout and signal loss, ensure stable operation of the vehicle-mounted system, and ultimately improve user experience and vehicle performance. Then the second judgment module 40 determines whether the electromagnetic interference trend has the same electromagnetic waveform to execute the corresponding steps.For example, when the system determines that the electromagnetic interference trend does not have the same electromagnetic waveform, the system will think that the current interference signal may be new, changing or irregular, which means that the interference source may be changing, and the system has not yet preset this interference mode. The system will further evaluate and confirm the electromagnetic interference source, and it is necessary to obtain more detailed interference data through electromagnetic sensors, rescan the spectrum, and further analyze whether the interference source has changed (such as frequency fluctuations, intensity changes, etc.). At the same time, if the interference source is more sudden or cannot be immediately identified, the system should initiate temporary mitigation measures, such as reducing the power of signal transmission, or through other redundant paths (such as adding communication channels, adjusting data transmission, etc.). Priority, etc.) to avoid serious impact on the work of the central control system, and continuously monitor changes in the electromagnetic environment, especially after discovering a new interference source, collect and feedback interference data in real time, and ensure that the system can adapt to complex electromagnetic environments and avoid long-term signal problems by continuously updating interference models and adjusting optimization strategies; for example, when the system determines that the electromagnetic interference trend has the same electromagnetic waveform, the second execution module 50 will believe that the interference source has not changed. The system will monitor the electromagnetic wave transmission path based on the pre-set vehicle-mounted sensor network, and track and locate the electromagnetic interference source in real time based on these electromagnetic wave transmission paths. According to the different electromagnetic interference sources, the vehicle is dynamically adjusted. The signal transmission mode of the on-board central control screen and the central control box, the signal transmission mode specifically includes modulation mode, bandwidth selection and signal recovery; the system tracks the electromagnetic wave transmission path in real time based on the on-board sensor network, and can accurately locate the position of the electromagnetic interference source, which provides accurate data support for further analysis of the impact of the interference source, helping the system to quickly identify and isolate the interference source to prevent it from having a continuous impact on the stability of the on-board central control system. At the same time, when the system identifies that the interference source has not changed, it can dynamically adjust the signal transmission mode of the on-board central control screen and the central control box according to the positioning information of the interference source, including modulation mode, bandwidth selection and signal recovery strategy. This automated adjustment can adapt to the intensity of the interference in real time. and features to ensure the stability of data transmission, avoid problems such as touch failure, image jitter or signal loss, and through dynamic adjustment based on the location of the interference source, the system can intelligently respond to different electromagnetic interference scenarios, optimize the signal transmission path, and improve the response speed and image quality of the central control screen. Users can enjoy a smoother and more stable operation experience during use, reduce the performance degradation of the central control screen caused by interference, and thus enhance the overall user experience. Dynamic adjustment of the signal transmission mode can not only optimize the data link, but also improve the anti-interference ability according to real-time interference changes, which makes the vehicle system more resilient and adaptive in the electromagnetic interference environment, reducing the negative impact of interference on system performance. ;

[0039] In this embodiment, the execution module further includes: An identification unit, used to identify different types of electromagnetic interference sources based on a preset spectrum analyzer, wherein the electromagnetic interference sources specifically include radio frequency interference, radiation interference and conducted interference; A judging unit, used to judge whether the electromagnetic interference source reaches a preset abnormal signal strength; An execution unit is used to extract the frequency characteristics of the electromagnetic interference source, and if so, obtain the interference source type corresponding to the electromagnetic interference source according to the frequency characteristics, and calculate the interference range of the electromagnetic interference source according to the interference source type, wherein the frequency characteristics specifically include the modulation mode and duration, and the interference source type specifically includes a constant signal and a pulse signal.

[0040] In this embodiment, the system identifies different types of electromagnetic interference sources based on a pre-set spectrum analyzer. The electromagnetic interference sources specifically include radio frequency interference, radiation interference and conducted interference. The system then determines whether these electromagnetic interference sources reach a pre-set abnormal signal strength to execute corresponding steps. For example, when the system determines that a certain electromagnetic interference source does not reach the pre-set abnormal signal strength, the system will believe that although the current electromagnetic interference exists, the intensity is not enough to pose a threat to the normal operation of the vehicle-mounted central control system. The system will not immediately adjust the signal transmission mode, maintain the current data link configuration, avoid unnecessary intervention and resource consumption, and continuously monitor the electromagnetic interference source and record its intensity change trend. Although the current interference intensity has not reached an abnormal level, the system can use it as an early warning signal for potential problems. By regularly evaluating the intensity changes of the electromagnetic interference source, the system can predict whether the interference source will intensify at some point in the future, be prepared to respond, and maintain flexibility. When the intensity of the electromagnetic interference source changes, it can respond quickly according to the change. If the interference intensity gradually increases and exceeds the threshold, the system should be able to adjust the signal transmission mode in time, improve the filter performance, and even enable emergency measures such as redundant communication channels. For example, when the system determines that a certain electromagnetic interference source has reached a preset abnormal signal strength, the system will consider that the current electromagnetic interference poses a threat to the operation of the vehicle's central control. The system will extract the frequency characteristics of the electromagnetic interference source. The frequency characteristics specifically include modulation mode and duration. According to different frequency characteristics, the interference source type corresponding to the electromagnetic interference source is obtained. The interference source type specifically includes constant signal and pulse signal. Based on these interference source types, the electromagnetic interference source is calculated. interference range; by extracting the frequency characteristics of the electromagnetic interference source (such as modulation mode and duration), the system can accurately distinguish whether the interference source is a constant signal or a pulse signal, which enables the system to take tailored intervention measures for different types of interference sources and improve the accuracy and efficiency of coping with electromagnetic interference. At the same time, based on the identification of the interference source type (constant signal or pulse signal) and the calculation of the interference range, the system can predict the impact range of the interference source on the vehicle's central control system. Through this prediction, the system can adjust the signal transmission path, optimize the bandwidth selection and modulation method in advance to ensure that the communication between the central control screen and the central control box is not affected. By analyzing the characteristics of the electromagnetic interference source, the system can dynamically adjust the response strategy. For example, the impact of pulse signals and constant signals on signal transmission is different.

At the same time, the filter configuration is automatically adjusted to enhance the filtering effect on specific frequency bands and reduce the impact of interference signals. For example, the band-stop filter is added to the overlapping frequency band to filter out unnecessary frequency components. For serious spectrum overlap, the system can change the modulation mode of the signal (such as from QAM modulation to more anti-interference PSK modulation) to enhance the anti-interference ability of the signal. According to the characteristics of the electromagnetic interference source, the bandwidth of the signal is adjusted to limit the impact of the frequency range of the interference source and reduce the occurrence of cross interference. For example, reduce the use of broadband spectrum and use narrower frequency bands to reduce overlap with other spectrums. In severe interference situations, the system can enable redundant data links, such as backing up data transmission paths through multi-path communication or using other communication protocols (such as Wi-Fi, Bluetooth, etc.) to ensure the stability of the central control screen. For example, when the system determines that the degree of influence of the mutual interference between electromagnetic interference sources on the signal is different, the system will consider that the signal interference generated by these interference sources does not have similar characteristics. The system will divide the interference priorities corresponding to these mutual interference effects, and obtain the link status between the vehicle-mounted central control screen and the central control box according to different interference priorities. The link status specifically includes connection interruption, data loss and signal quality degradation, and dynamically adjusts the pre-set communication signal waveform. The communication signal waveform specifically includes frequency hopping, spread spectrum and orthogonal waveform; the system can more accurately judge which interference sources have a greater impact on the communication between the vehicle-mounted central control screen and the central control box, and which have a smaller impact by identifying the different degrees of impact of the interaction between the interference sources on the signal. In this way, the system can take more targeted optimization measures, thereby effectively reducing unnecessary interference processing and avoiding waste of resources. At the same time, according to the link status (such as connection interruption, data loss and signal quality degradation) and interference priority, the communication signal waveform (such as frequency hopping, spread spectrum and orthogonal waveform) is dynamically adjusted.These adjustments can effectively deal with different types of interference and improve the stability and reliability of communication links. For example, frequency hopping technology can effectively avoid fixed-frequency interference, while spread spectrum technology can increase the signal's anti-interference ability. By real-time monitoring and interference priority division, the system can more flexibly adapt to changes in different electromagnetic environments. When the impact of certain interference sources is large, the system can give priority to processing these interferences and ensure the transmission of high-priority signals, thereby ensuring the stable operation of the vehicle's central control system in a complex electromagnetic environment. By obtaining link status information (such as connection interruption, data loss, and signal quality degradation), it can promptly detect and respond to communication problems and take appropriate measures (such as adjusting the signal waveform) to restore the stability of the link. This mechanism helps the system adjust communication strategies more intelligently to ensure unimpeded data transmission between the vehicle's central control screen and the central control box.

If necessary, the surrounding environment can be scanned by a spectrum analyzer to identify potential signal sources and update the filter's frequency band settings to ensure that all interference sources are processed. In addition, multi-channel signal processing technology is introduced to increase the filter's capture capability by processing signals in multiple frequency bands at the same time, such as using broadband filters or adaptive filtering technology, so that the system can more flexibly adjust the frequency band range and signal processing strategy; for example, when the system determines that the bandwidth range of the signal filter detects a pre-set number of signal frequency bands, the system will It is believed that the bandwidth of the signal filter can cover all expected signal frequency bands.

[0050] In this embodiment, the system collects the communication data between the vehicle-mounted central control screen and the central control box based on the data packet capturer pre-installed in the vehicle. The communication data specifically includes packet loss rate, delay, transmission rate and signal strength, and then the system determines whether these communication data reach the preset data quality to execute the corresponding steps; for example, when the system determines that the communication data can reach the preset data quality, the system will consider that the communication link between the vehicle-mounted central control screen and the central control box is stable and reliable, and can effectively transmit information without obvious data loss, excessive delay or signal attenuation problems. The system will continue to use the current communication configuration to ensure that the vehicle-mounted central control system works efficiently and stably in the current state. In this case, the system does not need to make additional adjustments and continues to maintain the existing bandwidth, transmission protocol and signal adjustment settings.

This ensures that the safety of the vehicle is not affected when the signal is unstable, minimizes safety hazards, and improves the reliability and security of driving. At the same time, by dynamically adjusting the priority of different types of data streams, the system can reasonably allocate communication resources in the case of limited bandwidth or poor signal quality, and give priority to the transmission of key operation data streams (such as vehicle speed, engine status, feedback from driving assistance systems, etc.), ensuring the real-time nature of the vehicle's core control operations and avoiding communication problems. The system can appropriately reduce the priority of non-safety but critical auxiliary data streams (such as in-vehicle entertainment systems, non-critical driving data, etc.) or delay transmission when the communication quality is poor, thereby ensuring that the overall stability and reliability of the system will not be affected in a harsh communication environment. Through such priority adjustments, the system can optimize under limited resources and reduce the risk of information loss. By giving priority to high-priority data streams, the system can avoid failures or interruptions caused by poor communication quality. The normal transmission of emergency data and critical operation data can ensure that vehicle functions are not affected and avoid major problems or failures caused by untimely or lost information transmission. ;
