[0072] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are used to explain this application and are not intended to limit this application.

[0073] The cable current signal data acquisition method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown, a terminal 102 communicates with a cable current signal data acquisition system 104 via a network. The current signal data acquisition system 104 includes a signal acquisition component 105, a signal filtering component 106, a signal conversion component 107, a data transmission component 108, and a controller 109.

The data storage system can be integrated with the current signal data acquisition system 104 or placed on a cloud or other network server.

[0074] Specifically, the user operates on the terminal 102 to trigger the current signal data acquisition control. The terminal 102 responds to the trigger operation and sends a current signal data acquisition request to the current signal data acquisition system 104. The current signal data acquisition system 104 responds to the current signal data acquisition request, samples the current signal data of the cable through the signal acquisition component 105, and filters the sampled current signal data through the signal filtering component 106. The filtered current signal data is then converted through the signal conversion component 107 to obtain the current signal data corresponding to the current signal data, and the filtered current signal data is transmitted to the controller through the data transmission component 108. Finally, the controller 109 obtains the current of the target cable. signal data, and detect the fluctuation amplitude, signal-to-noise ratio and packet loss rate of the current signal data; according to the fluctuation amplitude, signal-to-noise ratio and packet loss rate, respectively verify the multiple data processing components corresponding to the current signal data to obtain verification results, wherein the multiple data processing components include a signal acquisition component, a signal filtering component and a data transmission component; according to the verification results, locate the abnormal component and the component parameters to be corrected corresponding to the abnormal component from the signal acquisition component, the signal filtering component and the data transmission component, and correct the parameters of the component to be corrected; when the correction of the parameters of the component to be corrected is completed, return to the data acquisition step until it is determined that the multiple data processing components have passed the verification, and use the acquired current signal data as the target current signal data.

[0075] The terminal 102 may be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices may include smart speakers, smart TVs, smart air conditioners, smart car devices, and projectors. Portable wearable devices may include smart watches, smart bracelets, and head-mounted devices. Head-mounted devices may include virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, and the like.

[0076] In an exemplary embodiment, Figure 2 As shown, a method for obtaining current signal data of a cable is provided, and the method is applied to Figure 1The controller 109 in FIG. 1 is used as an example for explanation.

[0077] S100, data acquisition step: acquiring current signal data of a target cable, and detecting the fluctuation amplitude, signal-to-noise ratio, and packet loss rate of the current signal data.

[0078] Among them, the fluctuation amplitude is an important parameter that describes the strength of signal data and is usually used to evaluate the change in the amplitude of the wave. In signal data processing, the fluctuation amplitude of signal data can represent the change in the amplitude of the signal within a time period. Specifically, the fluctuation amplitude of the current signal data is the difference between the maximum current and the minimum current of the current signal data within a single sampling period. The signal-to-noise ratio is an indicator that measures the signal strength relative to the background noise strength. Its calculation is based on the ratio of signal power to noise power. This ratio can be used to indicate the quality of the signal. The higher the signal-to-noise ratio, the greater the proportion of useful information in the signal and the smaller the noise. The packet loss rate is the ratio of the number of data packets lost in the test to the number of data groups sent.

[0079] Specifically, the present application is applied to a current signal data acquisition system for a cable, wherein the current signal data acquisition system includes a signal acquisition component, a signal filtering component, a signal conversion component, a data transmission component and a controller.

[0080] Among them, the signal acquisition component is used to sample the current signal of the cable. In actual applications, the signal acquisition component is generally a current transformer; the signal filtering component is connected to the signal acquisition component and is used to filter the sampled current signal. In actual applications, the signal filtering component is a low-pass filter, a high-pass filter, or a band-stop filter. This application generally selects a low-pass filter; the signal conversion component is connected to the signal filtering component and is used to perform analog-to-digital conversion on the filtered current signal to obtain current signal data corresponding to the current signal; the data transmission component is used to transmit the current signal data to the controller; the controller is respectively connected to the signal acquisition component, the signal filtering component, the signal conversion component and the data transmission component, and is used to obtain the current signal data of the cable and detect the fluctuation amplitude, signal-to-noise ratio and packet loss rate of the current signal data; based on the fluctuation amplitude, signal-to-noise ratio and packet loss rate, the current signal data is checked to see if it is abnormal through the detected information. If the current signal data is abnormal, it is considered that the process of obtaining the current signal data is abnormal.

[0081] In an exemplary embodiment, the signal conversion component in the current signal data acquisition system includes an amplification component connected to the signal filtering component and an analog-to-digital conversion component connected to the amplification component. The amplification component is used to amplify the filtered current signal, and the analog-to-digital conversion component is used to perform analog-to-digital conversion on the amplified current signal to obtain current signal data corresponding to the current signal.

[0082] In an exemplary embodiment, the data transmission component in the current signal data acquisition system includes a wireless communication component and a display component. The wireless communication component is connected to the signal conversion component to perform analog-to-digital conversion on the filtered current signal. The display component is connected to the wireless communication component to display the current signal data. In actual applications, the display component is generally a display screen.

[0083] In an exemplary embodiment, the current signal data acquisition system further includes a storage component, etc. The storage component is connected to the signal acquisition component, the signal filtering component, the signal conversion component, and the data transmission component, respectively, to store the current signal and the current signal data corresponding to the current signal.

[0084] S200 , verifying multiple data processing components corresponding to the current signal data according to the fluctuation amplitude, signal-to-noise ratio, and packet loss rate to obtain verification results.

[0085] Among them, multiple data processing components include signal acquisition components, signal filtering components and data transmission components.

[0086] Specifically, each data processing component of the current signal data is verified based on the fluctuation amplitude, signal-to-noise ratio, and packet loss rate. Furthermore, the signal acquisition component of the current signal data is verified based on the fluctuation amplitude, the signal filtering component of the current signal data is verified based on the signal-to-noise ratio, and the data transmission component of the current signal data is verified based on the packet loss rate. Furthermore, the verification of each data processing component corresponding to the current signal data can be performed simultaneously or one by one.

[0087] S300 , based on the verification result, locate the abnormal component and the component parameters to be corrected corresponding to the abnormal component from the signal acquisition component, the signal filtering component and the data transmission component, and correct the component parameters to be corrected.

[0088] Specifically, the verification result may be that the verification of multiple data processing components has passed, or at least one data processing component has failed the verification, such as there is an abnormality in the signal acquisition component, or there are abnormalities in the signal acquisition component, signal filtering component and data transmission component.

[0089] When at least one data processing component fails the verification, the abnormal component is located from the signal acquisition component, the signal filtering component and the data transmission component. For example, when the signal acquisition component fails the verification, the abnormal component is located as the signal acquisition component; when the signal filtering component fails the verification, the abnormal component is located as the signal filtering component; when both the signal filtering component and the data transmission component fail the verification, the abnormal components are located as the signal filtering component and the data transmission component.

[0090] Furthermore, after locating the abnormal component, it is necessary to determine the component parameters to be corrected corresponding to the abnormal component and correct the parameters of the abnormal component to be corrected. The component parameters to be corrected in the signal acquisition component are factors that may affect the signal acquisition of the current signal data; the component parameters to be corrected in the signal filtering component are factors that may affect the signal filtering of the current signal data; and the component parameters to be corrected in the data transmission component are factors that may affect the data transmission of the current signal data.

[0091] S400, when the parameter correction of the component to be corrected is completed, return to the data acquisition step until it is determined that the multiple data processing components have passed the verification, and the acquired current signal data is used as the target current signal data.

[0092] Specifically, after correcting the parameters of the components to be corrected in the abnormal component, the abnormal component is corrected to a normal data processing component, and the current signal data acquisition process can be performed normally. Therefore, when the correction is complete, the data acquisition step can be returned to reacquire new current signal data, and the multiple data processing components corresponding to the newly acquired current signal data can be verified again to determine whether a new abnormality has occurred. Once it is determined that all multiple data processing components have passed the verification, the acquired current signal data is used as the target current signal data.

[0093] In the current signal data acquisition method of the above-mentioned cable, during the entire process, the fluctuation amplitude, signal-to-noise ratio and packet loss rate of the current signal data of the target cable are used to comprehensively verify whether there are any abnormalities in the signal acquisition component, signal filtering component and data transmission component. The verification is more accurate, and based on the verification results, the abnormal components and the component parameters to be corrected corresponding to the abnormal components are accurately located from the signal acquisition component, signal filtering component and data transmission component, so as to accurately correct the parameters of the component to be corrected. When the correction of the parameters of the component to be corrected is completed, the data acquisition step is returned until it is determined that multiple data processing components have passed the verification, and the acquired current signal data is used as the target current signal data. At this time, the acquired target current signal data is accurate current signal data.

[0094] In an exemplary embodiment, Figure 3 As shown, S200 also includes:

[0095] S220 , verifying the signal acquisition component corresponding to the current signal data according to the fluctuation amplitude.

[0096] S240 , when the signal acquisition component passes verification, verify the signal filtering component corresponding to the current signal data according to the signal-to-noise ratio.

[0097] S260 , when the signal filtering component passes verification, verify the data transmission component corresponding to the current signal data according to the packet loss rate.

[0098] Specifically, in the process of verifying the various data processing components corresponding to the current signal data in sequence according to the fluctuation amplitude, signal-to-noise ratio and packet loss rate, first, the signal acquisition component corresponding to the current signal data is verified according to the fluctuation amplitude, secondly, the signal filtering component corresponding to the current signal data is verified according to the signal-to-noise ratio, and finally, the data transmission component corresponding to the current signal data is verified according to the packet loss rate.

[0099] Furthermore, this embodiment does not blindly verify each data processing component in sequence, but only starts to verify the next data processing component when the previous data processing component fails the verification. For example, after the signal acquisition component fails the verification, when the signal filtering component continues to be verified, the current signal data has become abnormal due to the signal acquisition component that failed the previous verification. Therefore, the current signal data at this time is already abnormal data. When the signal filtering component is verified, the current signal data will also be abnormal data. It is impossible to determine whether the signal filtering component corresponding to the current signal data can pass the verification through the abnormal data.

[0100] Specifically, based on the fluctuation amplitude, the signal acquisition component corresponding to the current signal data is verified. If the signal acquisition component passes the verification, the signal filtering component corresponding to the current signal data is verified based on the signal-to-noise ratio. If the signal filtering component passes the verification, the data transmission component corresponding to the current signal data is verified based on the packet loss rate.

[0101] In an exemplary embodiment, when the verification of the signal acquisition component of the current signal data fails based on the fluctuation amplitude, there is no need to perform a subsequent verification operation of the signal filtering component, but it is necessary to correct the parameters of the component to be corrected in the signal acquisition component; similarly, when the verification of the signal filtering component of the current signal data fails based on the signal-to-noise ratio, there is no need to perform a subsequent verification operation of the data transmission component, but it is necessary to correct the parameters of the component to be corrected in the signal filtering component.

[0102] In an exemplary embodiment, when the verification of the signal acquisition component corresponding to the current signal data fails based on the fluctuation amplitude, a subsequent verification operation of the signal filtering component can also be performed. When the verification of the signal filtering component of the current signal data fails based on the signal-to-noise ratio, a subsequent verification operation of the data transmission component can also be performed.

[0103] In the above embodiment, according to the fluctuation amplitude, signal-to-noise ratio and packet loss rate, the multiple data processing components corresponding to the current signal data are verified one by one, so that the data acquisition process of the current signal data can be verified more comprehensively, and the abnormal components and the component parameters to be corrected corresponding to the abnormal components can be located in time from the signal acquisition component, the signal filtering component and the data transmission component, and the component parameters to be corrected can be corrected. Subsequently, data can be acquired through the corrected components to obtain more accurate current signal data.

[0104] In an exemplary embodiment, verifying the signal acquisition component corresponding to the current signal data according to the fluctuation amplitude includes:

[0105] When the fluctuation amplitude is less than or equal to the preset first fluctuation amplitude threshold, it is determined that the signal acquisition component corresponding to the current signal data has passed the verification; when the fluctuation amplitude is greater than the preset first fluctuation amplitude threshold, it is determined that the signal acquisition component corresponding to the current signal data has failed the verification.

[0106] Specifically, the controller is used to obtain current signal data within a single sampling period and calculate the fluctuation amplitude of the current signal data. If the fluctuation amplitude of the current signal data is greater than a preset first fluctuation amplitude threshold, it is determined that the signal acquisition component of the current signal data has failed the verification and the sampling stability of the cable current does not meet the requirements; if the fluctuation amplitude of the current signal data is less than or equal to the preset first fluctuation amplitude threshold, it is determined that the signal acquisition component of the current signal data has passed the verification and the sampling stability of the cable current meets the requirements.

[0107] In the above embodiment, by setting a preset first fluctuation amplitude threshold, it is possible to accurately determine whether the signal acquisition component of the current signal data passes the verification, and further determine whether the sampling stability of the cable current meets the requirements.

[0108] In an exemplary embodiment, verifying a signal filter component corresponding to the current signal data according to the signal-to-noise ratio includes:

[0109] When the signal-to-noise ratio is greater than the preset first signal-to-noise ratio threshold, it is determined that the signal filtering component corresponding to the current signal data has passed the verification; when the signal-to-noise ratio is less than or equal to the preset first signal-to-noise ratio threshold, it is determined that the signal filtering component corresponding to the current signal data has failed the verification.

[0110] Specifically, the controller obtains the signal-to-noise ratio of the current signal data sampled within a single cycle. If the signal-to-noise ratio of the current signal data sampled within a single cycle is less than or equal to a preset first signal-to-noise ratio threshold, it is determined that the sampling reliability of the cable current does not meet the requirements, and the signal filtering component of the current signal data fails the verification; if the signal-to-noise ratio of the current signal data sampled within a single cycle is greater than the preset first signal-to-noise ratio threshold, it is determined that the sampling reliability of the cable current meets the requirements, and the signal filtering component of the current signal data passes the verification.

[0111] In the above embodiment, by setting the preset first signal-to-noise ratio threshold, it is possible to accurately determine whether the signal filtering component of the current signal data passes the verification, and further determine whether the sampling reliability of the cable current meets the requirements.

[0112] In an exemplary embodiment, the component parameters to be corrected include at least one of a first rectifier element parameter of the signal acquisition component, a current transformer parameter of the signal acquisition component, a second rectifier element parameter of the signal filtering component, a filter parameter of the signal filtering component, and a state control parameter of the data transmission component; and correcting the component parameters to be corrected includes:

[0113] In the case where the abnormal component is a signal acquisition component, the first rectifier element parameters or the current transformer parameters are corrected, wherein the corrected first rectifier element parameters and the corrected current transformer parameters are both used to increase the sampling frequency of the signal acquisition component for current signal data; in the case where the abnormal component is a signal filtering component, the second rectifier element parameters or the filter parameters are corrected, wherein the corrected second rectifier element parameters and the corrected filter parameters are both used to reduce the filtering cutoff frequency of the signal filtering component for current signal data; in the case where the abnormal component is a data transmission component, the state control parameters are corrected, and the corrected state control parameters are used to switch the transmission state parameters of the data transmission component from high-speed communication state parameters to anti-interference low-speed communication state parameters.

[0114] Specifically, when the abnormal component is a signal acquisition component, the signal acquisition component in the current signal data acquisition system is in a working state. The reasons why the abnormality of the signal acquisition component occurs may be as follows:

[0115] The first method is: During the operation of the signal acquisition component, if the current in the measured cable of the current transformer is too large, it may cause distortion of the output signal and lead to deviations in the sampled current signal. In this case, it is necessary to adjust the sampling frequency of the current signal data by adjusting the current transformer parameters related to the sampling frequency of the current signal data in the signal acquisition component. Furthermore, adjusting the current transformer parameters generally means adjusting the current transformer parameters to increase the sampling frequency of the current signal data. For example, the sampling frequency of the current signal data can be increased by increasing the magnitude and amplitude of the current transformer parameters.

[0116] The second type: Due to long-term use, the forward voltage drop of the rectifier element is different, causing ripples in the output DC signal, thereby interfering with the subsequent current signal processing and causing fluctuations in the sampled data. At this time, it is necessary to adjust the sampling frequency of the current signal data by adjusting the first rectifier element parameters related to the sampling frequency of the current signal data in the signal acquisition component. For example, the sampling frequency of the current signal data can be increased by increasing the size and amplitude of the first rectifier element parameters.

[0117] By increasing the sampling frequency of the current signal data, more data points can be obtained. When the signal is subsequently processed, more information can be used to distinguish between the real signal components and the distorted components, further improving the sampling stability of the cable current.

[0118] When the abnormal component is a signal filter component, the signal filter component in the current signal data acquisition system is in working condition. The reasons for the abnormality of the signal acquisition component may be as follows:

[0119] The first type: Due to long-term use, the forward voltage drop of the rectifier element of the signal filtering component is different, resulting in ripples in the output DC signal, which interferes with the subsequent processing of the current signal and causes fluctuations in the sampled data. Therefore, the filtering cutoff frequency of the signal filtering component can be reduced by adjusting the parameters of the second rectifier element in the signal filtering component that are related to the filtering cutoff frequency of the current signal data. For example, the filtering cutoff frequency of the signal filtering component can be reduced by reducing the size and amplitude of the parameters of the second rectifier element of the signal filtering component.

[0120] The second type: Due to excessive noise, data loss occurs in the current signal data. Therefore, the filter parameters related to the filter cutoff frequency of the current signal data in the signal filter component can be adjusted to reduce the filter cutoff frequency of the signal filter component. For example, the filter cutoff frequency of the signal filter component can be reduced by reducing the size and amplitude of the filter parameters of the signal filter component.

[0121] Lowering the filter cutoff frequency of the signal filter component can enable the filter to better attenuate ripple and make the output signal closer to the ideal DC signal. By reducing the filter cutoff frequency, the noise content in the signal can also be reduced, so that the noise cannot interfere with the signal filtering process, further improving the sampling stability of the cable current.

[0122] When the abnormal component is a data transmission component, it means that an abnormality has occurred in the data transmission process. Generally, the abnormality of the data transmission component is due to signal loss caused by unstable communication. Therefore, the state control parameters of the data transmission component can be adjusted to switch the transmission state of the data transmission component from a high-speed communication state to an anti-interference low-speed communication state, that is, the data transmission component of the current signal data is switched from a high-speed communication module to an anti-interference low-speed communication module. Although the data transmission speed is slowed down, the anti-interference performance is improved, which can avoid data loss caused by unstable communication, thereby improving the stability of data transmission.

[0123] In the above embodiment, the parameters of the components to be corrected in the abnormal components are corrected by different correction methods. The correction process is more accurate and the correction efficiency is higher. The parameters of the components to be corrected of the abnormal components corresponding to the current signal data can be corrected in time to obtain more accurate current signal data.

[0124] In an exemplary embodiment, increasing the sampling frequency of the signal acquisition component for current signal data includes:

[0125] A first difference between the fluctuation amplitude and a preset fluctuation amplitude abnormality threshold is obtained; and according to the first difference, a sampling frequency of the signal acquisition component on the current signal data is increased.

[0126] Reduce the filter cutoff frequency of the signal filter component for current signal data, including:

[0127] A second difference between the signal-to-noise ratio and a preset signal-to-noise ratio abnormality threshold is obtained; and according to the second difference, a filtering cutoff frequency of the signal filtering component on the current signal data is reduced.

[0128] Specifically, when the fluctuation amplitude is greater than a preset fluctuation amplitude abnormality threshold, the signal acquisition component of the current signal data fails verification. When the fluctuation amplitude is less than or equal to the preset fluctuation amplitude abnormality threshold, the signal acquisition component of the current signal data passes verification. When the signal-to-noise ratio is less than or equal to the preset signal-to-noise ratio abnormality threshold, the signal filtering component of the current signal data fails verification. When the signal-to-noise ratio is greater than the preset signal-to-noise ratio abnormality threshold, the signal filtering component of the current signal data passes verification.

[0129] Specifically, the sampling frequency of the current signal data is determined according to the fluctuation amplitude of the current signal data, and the filtering cutoff frequency of the current signal data is determined according to the signal-to-noise ratio of the current signal data.

[0130] More specifically, with respect to the sampling frequency of the current signal data, the increase amplitude of the sampling frequency of the current signal data is determined by the difference between the fluctuation amplitude of the current signal data and a preset fluctuation amplitude abnormality threshold.

[0131] For example, when the difference between the fluctuation amplitude of the current signal data and the preset fluctuation amplitude abnormal threshold is within 3A, the sampling frequency of the current signal data is increased to 1.2 times the original value; when the difference between the fluctuation amplitude of the current signal data and the preset fluctuation amplitude abnormal threshold exceeds 3A, on the basis of being increased to 1.2 times the original value, the sampling frequency of the current signal data is increased by 5HZ for every 2A exceeding it. For example, the difference between the fluctuation amplitude of the current signal data and the preset fluctuation amplitude abnormal threshold is 7A, the current sampling frequency of the current signal data is 50Hz, and the increased sampling frequency of the current signal data is 50×1.2+5×2=70Hz.

[0132] Regarding the filtering cutoff frequency of the current signal data, the reduction amplitude of the filtering cutoff frequency of the signal filtering component is determined by the difference between the signal-to-noise ratio of the current signal data sampled in a single cycle and a preset signal-to-noise ratio abnormality threshold.

[0133] For example, when the difference between the signal-to-noise ratio of the current signal data sampled in a single cycle and the preset signal-to-noise ratio abnormal threshold is within 6dB, the filter cutoff frequency of the signal filter component is reduced to 0.92 times the original value; when the difference between the signal-to-noise ratio of the current signal data sampled in a single cycle and the preset signal-to-noise ratio abnormal threshold exceeds 6dB, on the basis of being reduced to 0.92 times the original value, the filter cutoff frequency of the signal filter component is reduced by 3Hz for every 2dB that exceeds it. For example, if the difference between the signal-to-noise ratio of the current signal data sampled in a single cycle and the preset signal-to-noise ratio abnormal threshold is 10dB, the current filter cutoff frequency of the signal filter component is 50Hz, and the reduced filter cutoff frequency of the signal filter component is 50×0.92-3×2=40Hz.

[0134] In the above embodiment, the sampling frequency of the current signal data can be accurately increased by the difference between the fluctuation amplitude and the preset fluctuation amplitude abnormality threshold, and the filtering cutoff frequency of the current signal data can be accurately reduced according to the difference between the signal-to-noise ratio and the preset signal-to-noise ratio abnormality threshold, thereby achieving accurate correction of the component parameters to be corrected in the abnormal component.

[0135] In an exemplary embodiment, based on the verification results, locating abnormal components and component parameters to be corrected corresponding to the abnormal components from the signal acquisition component, the signal filtering component, and the data transmission component includes:

[0136] When the verification result shows that the signal acquisition component fails the verification, the signal acquisition component is determined to be an abnormal component; when the fluctuation amplitude is not greater than the preset second fluctuation amplitude threshold, the first rectifier element parameter of the signal acquisition component is determined to be the component parameter to be corrected; when the fluctuation amplitude is greater than the preset second fluctuation amplitude threshold, the current transformer parameter of the signal acquisition component is determined to be the component parameter to be corrected.

[0137] Specifically, when the verification result shows that the signal acquisition component fails the verification, that is, when the fluctuation amplitude is greater than a preset first fluctuation amplitude threshold, the signal acquisition component is determined to be an abnormal component.

[0138] At this time, a preset second fluctuation amplitude threshold can also be set to locate the abnormal cause of the signal acquisition component with a large fluctuation amplitude that causes the current signal data to fail the verification, and then determine the component parameters to be corrected corresponding to the abnormal component based on the abnormal cause.

[0139] It can be understood that the three intervals divided according to the preset first fluctuation amplitude threshold and the preset second fluctuation amplitude threshold correspond to three situations respectively:

[0140] The first interval is when the fluctuation amplitude of the current signal data is less than or equal to the preset first fluctuation amplitude threshold, corresponding to the situation that: the sampling stability of the cable current meets the requirements, and the signal acquisition component of the current signal data passes the verification;

[0141] The second interval is when the fluctuation amplitude of the current signal data is greater than the preset first fluctuation amplitude threshold and less than or equal to the preset second fluctuation amplitude threshold. The corresponding situation is: due to long-term use, the forward voltage drop of the rectifier element of the signal acquisition component is different, causing the output DC signal to produce ripples, thereby interfering with the subsequent processing of the current signal and causing the sampled data to fluctuate. At this time, the signal acquisition component of the current signal data fails the verification. In this case, the first rectifier element parameter of the signal acquisition component can be determined as the component parameter to be corrected. By correcting the first rectifier element parameter, the sampling frequency of the current signal data of the signal acquisition component can be increased;

[0142] The third interval is when the fluctuation amplitude of the current signal data is greater than the preset second fluctuation amplitude threshold. The corresponding situation is: during the operation of the current transformer, if the current of the measured cable is too large, it may cause distortion of the output signal, resulting in deviation of the sampled current signal. At this time, the signal acquisition component of the current signal data fails to pass the verification, then the current transformer parameters of the signal acquisition component can be determined as the component parameters to be corrected. By correcting the current transformer parameters, the sampling frequency of the signal acquisition component for the current signal data can be increased.

[0143] That is to say, when the fluctuation amplitude is greater than the preset first fluctuation amplitude threshold and less than or equal to the preset second fluctuation amplitude threshold, the abnormal reason why the signal acquisition component of the current signal data fails to pass the verification is determined to be that the forward voltage drop of the rectifier element of the signal acquisition component is different, and it is necessary to correct the rectifier element parameters to increase the sampling frequency of the current signal data of the signal acquisition component; when the fluctuation amplitude is greater than the preset second fluctuation amplitude threshold, the abnormal reason why the signal acquisition component of the current signal data fails to pass the verification is determined to be that the current of the current signal data in the current transformer of the signal acquisition component is too large, and it is necessary to correct the current transformer parameters to increase the sampling frequency of the current signal data of the signal acquisition component.

[0144] In practical applications, the preset first fluctuation amplitude threshold is generally selected from the range of [6A, 8A], and the preset second fluctuation amplitude threshold is generally selected from the range of [9A, 11A]. For example, the preset first fluctuation amplitude threshold can be set to 7A, and the preset second fluctuation amplitude threshold can be set to 10A.

[0145] In an exemplary embodiment, when the fluctuation amplitude is greater than a preset first fluctuation amplitude threshold and less than or equal to a preset second fluctuation amplitude threshold, and when the fluctuation amplitude of the current signal data is greater than the preset second fluctuation amplitude threshold, the abnormal component is a signal acquisition component. At this time, the parameters of the component to be corrected in the signal acquisition component can be corrected to increase the sampling frequency of the current signal data.

[0146] In an exemplary embodiment, the controller can also determine that the sampling stability of the cable current does not meet the requirements when the fluctuation amplitude of the current signal data is greater than a preset first fluctuation amplitude threshold, and determine whether the sampling reliability of the cable current meets the requirements based on the signal-to-noise ratio of the current signal data sampled in a single cycle.

[0147] In the above embodiment, by setting a preset first fluctuation amplitude threshold and a preset second fluctuation amplitude threshold, the sampling stability of the cable current and the reasons affecting the sampling stability of the cable current are accurately determined, thereby reducing the impact of the reduced sampling accuracy of the cable current due to poor sampling stability of the cable current, and further improving the sampling stability of the cable current.

[0148] In an exemplary embodiment, based on the verification results, locating abnormal components and component parameters to be corrected corresponding to the abnormal components from the signal acquisition component, the signal filtering component, and the data transmission component includes:

[0149] When the verification result is that the signal filtering component fails the verification, the signal filtering component is determined to be an abnormal component; when the signal-to-noise ratio is less than or equal to the preset second signal-to-noise ratio threshold, the second rectifier element parameters of the signal filtering component are determined to be component parameters to be corrected; when the signal-to-noise ratio is greater than the preset second signal-to-noise ratio threshold, the filter parameters of the signal filtering component are determined to be component parameters to be corrected.

[0150] Specifically, when the verification result is that the signal filtering component fails the verification, that is, when the signal-to-noise ratio is less than or equal to the preset first signal-to-noise ratio threshold, the signal filtering component is determined to be an abnormal component.

[0151] At this time, a preset second fluctuation amplitude threshold may be set to locate the abnormal reason why the signal-to-noise ratio is small, resulting in the signal filter component of the current signal data failing the verification.

[0152] Furthermore, the three intervals divided according to the preset second signal-to-noise ratio threshold and the preset first signal-to-noise ratio threshold correspond to three situations respectively:

[0153] The first interval is when the signal-to-noise ratio of the current signal data sampled within a single cycle is less than or equal to the preset second signal-to-noise ratio threshold. The corresponding situation is: because the wireless communication module is affected by the interference of the surrounding environment during data transmission, the communication signal is interrupted or data packets are lost, which affects the real-time upload of the sampled data, and the signal filtering component of the current signal data fails to pass the verification; it should be noted that in wireless communication, the signal-to-noise ratio is one of the key indicators to measure the quality of signal transmission. When the signal-to-noise ratio is lower than a certain threshold, the noise in the signal may interfere with the correct transmission of the data, resulting in data packet loss. Therefore, the decrease in the signal-to-noise ratio is usually directly related to the increase in the packet loss rate. At this time, the filter parameters of the signal filtering component can be determined as the component parameters to be corrected. By adjusting the filter parameters, the filtering cutoff frequency of the signal filtering component for the current signal data can be reduced.

[0154] The second interval is when the signal-to-noise ratio of the current signal data sampled within a single cycle is greater than the preset second signal-to-noise ratio threshold and less than or equal to the preset first signal-to-noise ratio threshold. This corresponds to the situation where, due to long-term use, the forward voltage drop of the rectifier element varies, causing ripples in the output DC signal, thereby interfering with subsequent current signal processing and causing fluctuations in the sampled data. Consequently, the signal filter component of the current signal data fails verification. In this case, the parameters of the second rectifier element of the signal filter component can be determined as the component parameters to be corrected. By adjusting the parameters of the second rectifier element, the filter cutoff frequency of the current signal data filtered by the signal filter component can be reduced.

[0155] The third interval is when the signal-to-noise ratio of the current signal data sampled in a single cycle is greater than the preset first signal-to-noise ratio threshold. The corresponding situation is: the sampling reliability of the cable current meets the requirements, and the signal filtering component of the current signal data passes the verification.

[0156] In practical applications, the preset second SNR threshold is generally selected from the range of [45dB, 55dB], and the preset first SNR threshold is generally selected from the range of [56dB, 66dB]. For example, the preset second SNR threshold can be selected as 50dB, and the preset first SNR threshold can be selected as 60dB.

[0157] In an exemplary embodiment, when the signal-to-noise ratio is less than or equal to a preset second signal-to-noise ratio threshold or the signal-to-noise ratio is greater than the preset second signal-to-noise ratio threshold and less than or equal to a preset first signal-to-noise ratio threshold, the abnormal component is a signal filtering component. At this time, the filtering cutoff frequency of the current signal data can be reduced by adjusting the parameters of the component to be corrected corresponding to the abnormal component, so that the signal filtering component can better attenuate the ripple, making the output signal closer to the ideal DC signal, and further improving the sampling reliability of the cable current.

[0158] It should be explained that when the signal-to-noise ratio is greater than the preset second signal-to-noise ratio threshold and less than or equal to the preset first signal-to-noise ratio threshold, the abnormal reason for failing the verification is determined to be data interruption or data packet loss in the signal filtering component. The reason why the filter parameters are adjusted to reduce the filter cutoff frequency of the current signal data is that lowering the filter cutoff frequency can effectively attenuate high-frequency noise and reduce the interference of such noise on the signal, thereby improving the purity of the signal. This is beneficial for subsequent signal processing and data recovery. Even in the case of packet loss, the integrity of the signal can be guaranteed as much as possible. By lowering the filter cutoff frequency, the fluctuations in the signal can be better smoothed, making the output signal closer to the ideal DC signal. Lowering the filter cutoff frequency can further optimize the signal-to-noise ratio and reduce the impact of noise on the signal. Even in the case of a high packet loss rate, the optimized signal quality can provide more favorable conditions for subsequent communication module switching and data recovery.

[0159] In an exemplary embodiment, when a preset first signal-to-noise ratio threshold and a preset second signal-to-noise ratio threshold are set, the preset signal-to-noise ratio abnormality threshold is generally the smaller of the two thresholds, the preset second signal-to-noise ratio threshold. Based on the second difference information between the signal-to-noise ratio and the preset second signal-to-noise ratio threshold, the filter cutoff frequency of the current signal data by the signal filtering component is reduced. The rest is the same as described in the above embodiment and will not be repeated here.

[0160] In the above embodiment, by setting a preset first signal-to-noise ratio threshold and a preset second signal-to-noise ratio threshold, the sampling reliability of the cable current and the abnormal causes affecting the sampling reliability of the cable current are determined, and by accurately locating the abnormal components and the component parameters to be corrected corresponding to the abnormal components, the impact of the reduced accuracy of the acquisition of current signal data due to the low sampling reliability of the cable current is significantly reduced, and the accuracy of the acquisition of current signal data is further improved.

[0161] In an exemplary embodiment, verifying the data transmission component of the current signal data according to the packet loss rate includes:

[0162] When the packet loss rate is less than or equal to the preset packet loss rate threshold, it is determined that the data transmission component of the current signal data passes the verification; when the packet loss rate is greater than the preset packet loss rate threshold, it is determined that the data transmission component of the current signal data fails the verification.

[0163] Specifically, the controller is configured to obtain the number of packet losses and the total number of data transmissions within a number of transmission cycles, and calculate the packet loss rate. If the packet loss rate exceeds a preset packet loss rate threshold, the data transmission component of the current signal data is determined to have failed verification and the communication signal transmission quality does not meet the requirements. In this case, the component parameters to be corrected are determined as transmission state parameters. By triggering a transmission state parameter switching mechanism, the transmission state parameters are corrected, that is, the transmission state parameters of the data transmission component are switched from high-speed communication state parameters to low-speed communication state parameters for interference reduction.

[0164] It is understandable that the preset packet loss rate threshold is divided into two intervals, corresponding to the following two situations:

[0165] 1. When the packet loss rate is less than or equal to the preset packet loss rate threshold, the transmission quality of the communication signal meets the requirements and the system maintains the current transmission state of the communication module;

[0166] 2. When the packet loss rate exceeds the preset packet loss rate threshold, it indicates that the current data transmission component is subject to environmental interference, resulting in an increase in the packet loss rate. The system will switch to a backup communication transmission state with stronger anti-interference capabilities. When the packet loss rate returns to a normal range, the system can switch back to the high-speed communication transmission state. This design ensures both communication reliability and optimized transmission efficiency.

[0167] In practical applications, the value range of the preset packet loss rate threshold is usually [0.02, 0.04]. For example, the preset packet loss rate threshold can be set to 0.03.

[0168] More specifically, the packet loss rate is the ratio of the number of packet losses during data transmission to the total number of data transmissions within a number of transmission cycles.

[0169] In the above embodiment, by setting a preset packet loss rate threshold, the system can dynamically evaluate the transmission quality of communication data to avoid data loss due to unstable communication, and when it is detected that the packet loss rate exceeds the preset threshold, it automatically switches from a high-speed communication transmission state to a low-speed communication transmission state with stronger anti-interference ability. By achieving dynamic switching through the collaborative work of multiple communication transmission states, the stability of data transmission can be improved.

[0170] In an exemplary embodiment, a current signal data acquisition system includes a current transformer, a signal filtering component, an amplifying component, an analog-to-digital conversion component, a wireless communication component, and a controller.

[0171] The current signal of the cable is sampled through a current transformer, the sampled current signal is filtered through a signal filtering component, the filtered current signal is amplified through an amplifying component, and then the amplified current signal is converted from analog to digital through an analog-to-digital conversion component to obtain current signal data corresponding to the current signal, and the current signal data is transmitted to the controller using a wireless communication component.

[0172] The controller obtains current signal data corresponding to the sampled current signal, and detects the fluctuation amplitude, signal-to-noise ratio, and packet loss rate of the current signal data.

[0173] When the fluctuation amplitude is less than or equal to the preset first fluctuation amplitude threshold, it is determined that the signal acquisition component of the current signal data has passed the verification; when the fluctuation amplitude is greater than the preset first fluctuation amplitude threshold and less than or equal to the preset second fluctuation amplitude threshold, it is determined that the signal acquisition component of the current signal data has failed the verification, and the signal acquisition component is positioned as an abnormal component, and the abnormal reason for failing the verification is determined to be the different forward voltage drops of the rectifier elements of the signal acquisition component. At this time, the component parameter to be corrected corresponding to the abnormal component is positioned as the first rectifier element parameter in the signal acquisition component related to the signal acquisition frequency, and according to the first difference between the fluctuation amplitude and the preset first fluctuation amplitude threshold, Adjust the size and amplitude of the first rectifier element parameters of the signal acquisition component to increase the sampling frequency of the current signal data; when the fluctuation amplitude is greater than the preset second fluctuation amplitude threshold, determine that the signal acquisition component of the current signal data has failed the verification, locate the signal acquisition component as an abnormal component, and determine that the cause of the abnormality is that the current in the current signal data of the current transformer of the signal acquisition component is too large. At this time, locate the component parameter to be corrected corresponding to the abnormal component as the current transformer parameter of the signal acquisition component, and adjust the size and amplitude of the current transformer parameter according to the first difference between the fluctuation amplitude and the preset first fluctuation amplitude threshold to increase the sampling frequency of the current signal data.

[0174] In the case that the verification of the signal acquisition component passes, when the signal-to-noise ratio is greater than the preset second signal-to-noise ratio threshold and less than or equal to the preset first signal-to-noise ratio threshold, it is determined that the signal filtering component of the current signal data has failed the verification, and the signal filtering component is positioned as an abnormal component, and the abnormal reason for failing the verification is determined to be data interruption or data packet loss in the signal filtering component. At this time, the component parameters to be corrected corresponding to the abnormal component are positioned as the filter parameters of the signal filtering component, and the filter parameters are adjusted according to the first difference between the signal-to-noise ratio and the preset second signal-to-noise ratio threshold to reduce the filtering cutoff frequency of the signal filtering component for the current signal data; when the signal-to-noise ratio is less than or equal to the preset second signal-to-noise ratio threshold When the signal-to-noise ratio is greater than the threshold, it is determined that the signal filtering component of the current signal data has failed the verification, and the signal filtering component is positioned as an abnormal component, and the abnormal reason for failing the verification is determined to be that the forward voltage drop of the rectifier element of the signal filtering component is different. At this time, the component parameter to be corrected corresponding to the abnormal component is positioned as the second rectifier element parameter related to the filtering cutoff frequency in the signal filtering component, and according to the first difference between the signal-to-noise ratio and the preset second signal-to-noise ratio threshold, the second rectifier element parameter of the signal filtering component is adjusted to reduce the filtering cutoff frequency of the signal filtering component for the current signal data; when the signal-to-noise ratio is greater than the preset first signal-to-noise ratio threshold, it is determined that the signal filtering component of the current signal data has passed the verification.

[0175] When the signal filtering component passes the verification, when the packet loss rate is less than or equal to the preset packet loss rate threshold, it is determined that the data transmission component of the current signal data has passed the verification; when the packet loss rate is greater than the preset packet loss rate threshold, it is determined that the data transmission component of the current signal data has failed the verification. At this time, the component parameters to be corrected corresponding to the abnormal component are positioned as the state control parameters of the data transmission component, so as to switch the transmission state of the data transmission component from the high-speed communication state to the anti-interference low-speed communication state by adjusting the state control parameters.

[0176] When the parameter correction of the component to be corrected is completed, the process returns to the above data acquisition step until it is determined that the multiple data processing components have passed the verification, and the acquired current signal data is used as the target current signal data.

[0177] Based on the above analysis, it can be seen that the controller is used to determine the sampling frequency of the current signal data by the signal acquisition component according to the fluctuation amplitude of the current signal data, or to determine the filtering cutoff frequency of the current signal data by the signal filtering component according to the signal-to-noise ratio of the current signal data sampled in a single cycle, and the system can intelligently switch between multiple hardware modules with different communication characteristics according to the packet loss rate of data transmission.

[0178] That is, the sampling frequency of the current signal data is determined based on the fluctuation amplitude of the current signal data. During the operation of the current transformer, if the current in the measured cable is too large, it may cause distortion of the output signal, resulting in deviations in the sampled current signal. By increasing the sampling frequency of the current signal data, more data points can be obtained. In subsequent signal processing, richer information can be used to distinguish between true signal components and distorted components. The filter cutoff frequency is determined based on the signal-to-noise ratio of the current signal data sampled within a single cycle. Due to long-term use, the forward voltage drop of the rectifier components varies, causing ripples in the output DC signal, which interferes with subsequent current signal processing and causes fluctuations in the sampled data. By reducing the filter cutoff frequency, the filter can better attenuate the ripples, making the output signal closer to the ideal DC signal. Based on the packet loss rate statistics of the current signal data transmission, the system implements adaptive switching between multiple communication modules: when the packet loss rate exceeds a preset threshold, the communication module with stronger anti-interference capabilities is automatically activated; when the packet loss rate drops to a normal range, the communication module with a better transmission rate is switched to. This achieves a dynamic balance between communication reliability and transmission efficiency, improving the sampling stability of the cable current.

[0179] It should be understood that, although the various steps in the flowcharts involved in the above embodiments are shown in sequence as indicated by the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple components, and these steps or components are not necessarily performed at the same time, but can be performed at different times, and the execution order of these steps or components is not necessarily performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of steps or components in other steps.

[0180] Based on the same inventive concept, embodiments of the present application further provide a device for acquiring current signal data of a cable for implementing the aforementioned method for acquiring current signal data of a cable. The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations of the embodiments of one or more devices for acquiring current signal data of a cable provided below can be found in the limitations of the method for acquiring current signal data of a cable described above and will not be further elaborated here.

[0181] In an exemplary embodiment, Figure 4 As shown, a device for acquiring current signal data of a cable is provided, comprising: a data detection module 100, a verification module 200, a correction module 300 and a data acquisition module 400, wherein:

[0182] The data detection module 100 is used in the data acquisition step: obtaining the current signal data of the target cable and detecting the fluctuation amplitude, signal-to-noise ratio and packet loss rate of the current signal data;

[0183] A verification module 200 is configured to verify multiple data processing components corresponding to the current signal data based on the fluctuation amplitude, signal-to-noise ratio, and packet loss rate, and obtain verification results, wherein the multiple data processing components include a signal acquisition component, a signal filtering component, and a data transmission component;

[0184] The correction module 300 is used to locate the abnormal component and the component parameters to be corrected corresponding to the abnormal component from the signal acquisition component, the signal filtering component and the data transmission component according to the verification result, and correct the component parameters to be corrected;
