[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] With the development of power systems, the demand for current measurement is increasing. Currently, current sensors, such as shunts, Hall effect sensors, and electromagnetic current transformers, can be used for current measurement and monitoring. While each of these current sensors has its advantages, they still have limitations in different application scenarios, such as measurement accuracy, range limitations, cost, and power consumption. Currently, power systems commonly use fluxgate current sensors, which are sensors designed and manufactured based on the fluxgate effect principle. Fluxgate current sensors are widely used in power monitoring, fault detection, and other fields.

[0036] However, traditional fluxgate current sensors in current detection systems suffer from problems in core material selection, excitation methods, and signal processing. For example, firstly, traditional fluxgate current sensors typically use cobalt magnetic materials as cores; however, the processing and heat treatment of cobalt magnetic materials are relatively complex, increasing production costs and limiting the application range of traditional fluxgate current sensors, especially in power systems where cost control is crucial for large-scale current sensor deployments. Secondly, traditional fluxgate current sensors typically use external excitation sources, which makes the generation and processing of excitation signals relatively complex and requires additional power consumption, further increasing the complexity and cost of the power system. Thirdly, traditional fluxgate current sensors typically use analog circuits for signal processing, including signal amplification, filtering, and phase-sensitive detection. However, analog circuits have low integration, are susceptible to interference, and struggle to achieve high-precision and highly integrated signal processing flows, which is detrimental to... The application of fluxgate current sensors in portable and low-power devices; fourth, the saturation characteristics of the magnetic core material determine the measurement range of the fluxgate current sensor. When the measured current exceeds a certain value, the magnetic core will saturate, causing the output signal of the fluxgate current sensor to distort, reducing measurement accuracy and stability, and resulting in a low measurement range for traditional fluxgate current sensors, thus making them unsuitable for high-current applications; fifth, self-excited oscillating fluxgate circuits are easily affected by external environmental interference under high-frequency signals, leading to reduced measurement accuracy and affecting the stability and reliability of the fluxgate current sensor, thereby reducing its applicability in complex electromagnetic environments and limiting its application range in industrial and power systems; sixth, traditional zero-flux detection technology requires complex analog signal processing modules, which are difficult to simplify and integrate in fluxgate current sensors, affecting the overall performance and market competitiveness of the sensor and limiting its application range. Therefore, current detection systems using traditional fluxgate current sensors suffer from low detection accuracy.

[0037] Therefore, this application proposes a current detection system and a current detection method to solve the above-mentioned technical problems.

[0038] The following mainly introduces the current detection system and current detection method used in this application.

[0039] In one embodiment, such as Figure 1 As shown, a current detection system is provided, which includes an array of current sensors 11, an evaluation module 12, and a parameter control module 13 connected to each other.

[0040] The current sensor array 11 is used to detect the current in multiple detection areas where the current detection system is located, and to obtain the current detection result.

[0041] Evaluation module 12 is used to evaluate the performance of the current detection system based on the current detection results and the response parameters of the current detection system, and obtain the evaluation results.

[0042] The parameter control module 13 is used to adjust the circuit parameters of the current detection system when the evaluation results indicate that the current detection system is abnormal.

[0043] In this embodiment, the current detection system includes a current sensor array 11, an evaluation module 12, and a parameter control module 13. The current sensor array 11 is communicatively connected to the evaluation module 12, the evaluation module 12 is communicatively connected to the parameter control module 13, and the parameter control module 13 is communicatively connected to the current sensor array 11. The current sensor array 11 consists of multiple fluxgate current sensors. Both the parameter control module 12 and the evaluation module 13 may be equipped with computer devices for executing control or evaluation processes. For example, multiple detection areas can be pre-designed in the current detection system. The current sensor array 11 can then perform current detection on each of these multiple detection areas, obtaining current detection results, which are then transmitted to the evaluation module 12. The evaluation module 12 can receive the current detection results sent by the current sensor array 11 and can detect the response parameters of the current detection system in real time. Based on the current detection results and the response parameters, the performance of the current detection system can be evaluated, resulting in an evaluation result, which is then transmitted to the parameter control module 13. For example, the evaluation module 12 can use edge computing technology to perform real-time data processing to obtain the response parameters of the current detection system, thereby reducing latency and improving the response speed of the current detection system.

[0044] Furthermore, the parameter control module 13 can receive and monitor the evaluation results of the current detection system in real time, and determine whether the current detection system is abnormal based on the evaluation results. Therefore, if the evaluation results indicate an abnormality in the current detection system, the module can adaptively adjust the circuit parameters in the current detection system. For example, the parameter control module 13 can input the evaluation results into a machine learning model to identify faults or abnormalities in the current detection system, thereby achieving predictive maintenance, reducing downtime, and improving the overall reliability of the current detection system. In addition, the adjusted circuit parameters in the current detection system can be transmitted to the current sensor array 11, allowing the current sensor array 11 to perform more accurate current detection based on the adjusted circuit parameters. The response parameters may include, but are not limited to, parameters such as response speed and response delay; the performance of the current detection system may include, but is not limited to, the degree of signal distortion and response speed; and the circuit parameters may include, but are not limited to, parameters such as filtering parameters and control parameters.

[0045] In the aforementioned current detection system, the current detection system includes an interconnected current sensor array, an evaluation module, and a parameter control module. The current sensor array is used to detect current in multiple detection areas where the current detection system is located, obtaining current detection results. The evaluation module is used to evaluate the performance of the current detection system based on the current detection results and the response parameters of the current detection system, obtaining an evaluation result. The parameter control module is used to adjust the circuit parameters in the current detection system when the evaluation result indicates that the current detection system is abnormal. Since the current sensor array in this embodiment can detect current in multiple detection areas where the current detection system is located separately, it can obtain current detection results more accurately. Furthermore, this application can adjust the circuit parameters in the current detection system in real time through the evaluation module and the parameter control module, ensuring that the circuit parameters in the current detection system are always kept within the normal range. Using the adjusted circuit parameters for current detection further improves the accuracy of current detection, as well as the stability and reliability of the current sensor array.

[0046] Based on the structure of the current detection system described in the above embodiments, in one embodiment, the current sensor array includes multiple fluxgate current sensors connected in parallel;

[0047] Each fluxgate current sensor is used to detect the current to be measured in the detection area corresponding to each fluxgate current sensor, and to obtain the current detection result corresponding to each detection area.

[0048] In this embodiment, the current sensor array includes multiple fluxgate current sensors connected in parallel. This means that each fluxgate current sensor can be connected to both the evaluation module and the parameter modulation module, and each fluxgate current sensor corresponds to a different detection region. Based on this, for each fluxgate current sensor, the fluxgate current sensor can perform parallel current detection on the current to be measured in its corresponding detection region, obtaining the current detection result for that region. Optionally, the current sensor array can then transmit the current detection results for each detection region to the evaluation module 12 separately; alternatively, the current sensor array can use a data fusion algorithm to fuse the current detection results for each detection region and transmit the fused current detection result to the evaluation module 12. Furthermore, a real-time sensor calibration mechanism can be established to ensure the accuracy and consistency of the current detection results and reduce potential risks caused by measurement errors.

[0049] In this embodiment, the current sensor array includes multiple fluxgate current sensors connected in parallel. Each fluxgate current sensor is used to detect the current to be measured in its corresponding detection area, obtaining the current detection result for each detection area. Thus, different fluxgate current sensors can be used to perform parallel current detection on their respective detection areas, resulting in more accurate current detection, enhanced global sensing capability of the current detection system, and improved monitoring accuracy and response speed.

[0050] Based on the structure of the current detection system described in the above embodiments, in one embodiment, the fluxgate current sensor includes a magnetic core and a winding. The magnetic permeability of the material of the magnetic core is higher than a preset permeability threshold, and the number of turns and shape of the winding are determined according to the winding simulation model under different environmental conditions.

[0051] In this embodiment, the fluxgate current sensor includes a magnetic core and windings. The magnetic core material has a permeability higher than a preset permeability threshold. That is, this embodiment can select a novel high-permeability material as the magnetic core material to further improve permeability and reduce losses. Furthermore, the high-frequency characteristics of the magnetic core material can be experimentally tested to optimize its use. For example, the performance changes of the magnetic core material under different temperature conditions can be assessed in advance to ensure that the magnetic core material maintains high performance even in harsh environments. The novel high-permeability material may include, but is not limited to, soft magnetic alloys, cobalt-iron alloys, etc.

[0052] The number of turns and shape of the winding in this embodiment are determined based on winding simulation models under different environmental conditions. Optionally, firstly, a winding simulation model can be pre-constructed using preset simulation software, and multiphysics simulation can be performed on the winding simulation model to comprehensively consider the influence of different environmental conditions on winding performance, thereby determining a suitable number of turns and shape of the winding. The preset simulation software may include, but is not limited to, ANSYS Maxwell, COMSOL Multiphysics, etc., and environmental conditions may include, but are not limited to, temperature, current, etc. Secondly, 3D printing technology can be used to manufacture the winding support to more accurately control the geometry of the winding and reduce errors. Thirdly, parametric modeling methods can be used for finite element simulation to construct a winding simulation model, and the number of turns and the corresponding current of the winding can be optimized in the winding simulation model to ensure good performance under dynamic operating conditions. Of course, this embodiment does not limit the specific implementation method for determining the number of turns and shape of the winding.

[0053] In this embodiment, the fluxgate current sensor includes a magnetic core and a winding. The magnetic permeability of the magnetic core material is higher than a preset permeability threshold. By selecting a novel high-permeability material as the magnetic core material, the permeability can be further improved and losses reduced. Furthermore, by optimizing the material's performance under different temperature conditions, reliability and stability in extreme environments are ensured, increasing the system's applicability and lifespan. Since the number of turns and shape of the winding are determined based on winding simulation models under different environmental conditions, this embodiment comprehensively considers the impact of different environmental conditions on winding performance. Combining the advantages of different simulation software, it can more comprehensively understand the winding's performance under actual operating conditions, thereby ensuring that the winding structure can maintain better performance under actual operating conditions. This allows for the determination of a suitable number of turns and shape for the winding, improving the accuracy of the winding structure, reducing manufacturing errors, and making the winding performance more stable and reliable.

[0054] Based on the structure of the current detection system described in the above embodiments, in one embodiment, the parameter control module is specifically used to adjust the circuit parameters of the current detection system using a parameter adjustment algorithm when the evaluation result indicates that the current detection system is abnormal; the parameter adjustment algorithm includes at least one of fuzzy control algorithm, reinforcement learning algorithm and filtering algorithm.

[0055] In one embodiment, the parameter control module is specifically used to adjust the circuit parameters of the current detection system using fuzzy control algorithms and reinforcement learning algorithms when the evaluation results indicate that the current detection system is malfunctioning.

[0056] In one embodiment, the parameter control module is specifically used to adjust the filter parameters in the circuit parameters using a filtering algorithm when the evaluation result indicates that the current detection system is malfunctioning.

[0057] In this embodiment, when the evaluation result indicates an anomaly in the current detection system, the parameter control module may optionally employ an adaptive fuzzy control algorithm or a neural network control algorithm to dynamically adjust the control parameters in the current detection system according to the system state, thereby optimizing response speed and stability; alternatively, the parameter control module may employ a combined algorithm based on fuzzy control and reinforcement learning to flexibly adjust the circuit parameters in the current detection system, thereby optimizing desaturation response speed and improving the dynamic adaptability of the current detection system; or alternatively, the parameter control module may employ an adaptive filtering algorithm to dynamically adjust the filtering parameters in the circuit parameters according to signal changes, thereby enhancing the signal-to-noise ratio.

[0058] In this embodiment, the parameter control module is specifically used to adjust the circuit parameters in the current detection system using a parameter adjustment algorithm when the evaluation result indicates that the current detection system is abnormal. The parameter adjustment algorithm includes at least one of fuzzy control algorithm, reinforcement learning algorithm, and filtering algorithm. In this way, the circuit parameters in the current detection system can be dynamically adjusted through multiple parameter adjustment algorithms, thereby improving the response speed and stability of the current detection system.

[0059] Based on the structure of the current detection system described in the above embodiments, in one embodiment, the current detection system further includes a desaturation detection module, which is used to detect desaturation faults according to circuit parameters and obtain fault detection results.

[0060] In one embodiment, the desaturation detection module includes a signal generation module for generating an excitation signal when the fault detection result indicates that the current detection system has a desaturation fault.

[0061] In one embodiment, the desaturation detection module further includes a signal adjustment module, which is used to adjust the signal parameters of the excitation signal according to the circuit parameters.

[0062] In the embodiments of this application, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the current detection system in another embodiment. The current detection system also includes a desaturation detection module 14, which is connected to the parameter control module 13. Based on this, the desaturation detection module can acquire the circuit parameters adjusted in real time by the parameter control module, and can detect desaturation faults based on the adjusted circuit parameters to obtain fault detection results. For example, multiple trigger conditions can be preset, such as temperature and load changes. When the adjusted circuit parameters meet the trigger conditions, the fault detection result is determined to be a desaturation fault in the current detection system, thereby improving the system's response capability to saturation states. Furthermore, the design of the desaturation detection module can consider the performance of the circuit in the current detection system under high-frequency signals, and the circuit layout can be optimized based on the performance of the circuit under high-frequency signals to reduce parasitic effects, improve the stability of the current detection system under high-frequency signals, reduce circuit noise and parasitic effects, and improve the overall signal quality of the current detection system. A dual redundant control system can also be introduced into the current detection system to ensure that the backup system can be used immediately when the main control system fails.

[0063] In one embodiment, the desaturation detection module may include a signal generation module. This module generates an excitation signal when the fault detection result indicates a desaturation fault in the current detection system. This ensures a rapid return to normal operation after desaturation, reducing downtime and improving production efficiency. The excitation signal can include various waveforms such as sine waves, square waves, and triangular waves. Furthermore, the excitation signal can be flexibly configured according to different application requirements to adapt to different application scenarios, thereby improving the flexibility and adaptability of the current detection system. Additionally, a high-resolution digital-to-analog converter (DAC) can be used to process and output the excitation signal to ensure signal output accuracy, reduce signal distortion, and enhance the performance of the current detection system.

[0064] In one embodiment, the desaturation detection module further includes a signal adjustment module, which can adjust the signal parameters of the excitation signal according to the circuit parameters. Optionally, the signal adjustment module can employ various sensitivity adjustment methods to adaptively adjust the signal parameters of the excitation signal according to the circuit parameters. These sensitivity adjustment methods can include, but are not limited to, digital adjustment and analog adjustment, to ensure that the system maintains optimal performance under different operating conditions. Alternatively, a dynamic adjustment model can be pre-established and trained in the signal adjustment module. This allows the signal adjustment module to input the real-time adjusted circuit parameters into the dynamic adjustment model for signal adjustment, thereby automatically optimizing the signal parameters of the excitation signal to improve the recovery efficiency of desaturation faults.

[0065] In this embodiment, the current detection system further includes a desaturation detection module. This module detects desaturation faults based on circuit parameters and obtains the fault detection result. The desaturation detection module also includes a signal generation module. This module generates an excitation signal when the fault detection result indicates a desaturation fault in the current detection system, ensuring a rapid return to normal operation after desaturation, reducing downtime, and improving production efficiency. Furthermore, the desaturation detection module also includes a signal adjustment module. This module adjusts the signal parameters of the excitation signal based on the circuit parameters, thus improving the recovery efficiency from desaturation faults.

[0066] Based on the structure of the current detection system described in the above embodiments, in one embodiment, the zero flux detection circuit in the related art can be further optimized. Optionally, multi-channel parallel detection technology can be introduced into the zero flux detection circuit in the related art, so that the zero flux state can be detected in parallel, which can improve detection accuracy and redundancy, and ensure that the zero flux state can still be accurately monitored in the event of a fault; or, a hierarchical control module can be added to the zero flux detection circuit in the related art, so that the current detection system in different system states can be adaptively controlled and adjusted according to the system state of the current detection system by adopting a hierarchical adjustment strategy, thereby improving the flexibility of the current detection system; or, a fine-tuning circuit combined with an intelligent controller can be used to adjust the excitation current in real time to ensure that the magnetic flux is maintained in the zero flux state, optimize the working efficiency of the system, and reduce unnecessary energy consumption.

[0067] Based on the structure of the current detection system described in the above embodiments, in one embodiment, an electromagnetic shielding module can be added to the current detection system. Optionally, dynamic simulation tools can be used to analyze the performance of the electromagnetic shielding module in different frequency bands, which can provide a more comprehensive understanding of the shielding structure's performance in different frequency bands, allowing for targeted improvements to the electromagnetic shielding module and enhancing electromagnetic compatibility; alternatively, the sensitive areas in the current detection system can be comprehensively identified by combining simulation models and actually detected circuit parameters to optimize the shielding design; alternatively, environmentally friendly composite materials or bio-based materials can be used as the shielding structure materials in the electromagnetic shielding module, which not only improves the shielding effect but also meets green environmental protection standards and has broader application prospects; alternatively, the geometry and grounding design of the shielding structure can be optimized by conducting simulation experiments on different structural forms to improve electromagnetic compatibility; alternatively, internationally standardized testing methods can be developed to ensure that shielding structures of different batches meet consistent performance indicators, improving product reliability and market competitiveness.

[0068] After introducing the current detection system, the current detection method implemented using the current detection system will be described below. In one embodiment, such as... Figure 3 As shown, a current detection method is provided. Taking the application of this method to a current detection system in any of the above embodiments as an example, the current detection system includes an interconnected current sensor array, an evaluation module, and a parameter control module, and includes the following steps:

[0073] In the aforementioned current detection method, a current sensor array is controlled to detect current in multiple detection areas where the current detection system is located, obtaining current detection results. An evaluation module evaluates the performance of the current detection system based on the current detection results and the system's response parameters, obtaining an evaluation result. A parameter control module adjusts the circuit parameters in the current detection system when the evaluation result indicates an anomaly. Since the current sensor array in this embodiment can detect current in multiple detection areas separately, it can obtain more accurate current detection results. Furthermore, this application can adjust the circuit parameters in the current detection system in real time through the evaluation module and parameter control module, ensuring that the circuit parameters remain within the normal range. Using the adjusted circuit parameters for current detection further improves the accuracy of current detection and enhances the stability and reliability of the current sensor array.
