It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.
[0015] In some embodiments, Figure 1 This is a flowchart of a control method for a detection device provided in an embodiment of this application. In this embodiment, a control method for a detection device is provided. In this embodiment, the detection device is used to detect the real-time performance of a current transformer. The current transformer is a key sensing element in current closed-loop control. The detection device includes a current generator and a current processor. The current generator is used to generate an adjustable current signal, and the current processor is used to process the current signal in the detection device.
[0016] For example, a current transformer can be a sensing element in a frequency converter. As a core device for precise motor speed control, the reliability of the frequency converter directly determines the stability of the production process and the lifespan of the equipment. As a key sensing element in the closed-loop current control of the frequency converter, performance degradation of the current transformer will lead to a chain of faults such as current feedback distortion and motor control inaccuracy. The detection device in this embodiment is used to detect whether the current transformer has performance degradation or other problems.
[0017] For example, the current generator and the current processor are connected by a circuit.
[0018] For example, the current generator and the current transformer are connected by a circuit.
[0019] For example, the current processor and the current transformer are connected by a circuit.
[0020] like Figure 1 As shown, the control method of the detection device in this embodiment includes: Step S101: Control the current generator to send the first current signal to the current transformer and the current processor respectively; After the current generator is started, the control current generator sends a first current signal to the current transformer. At the same time, the control current generator sends a first current signal to the current processor. The first current signal is a preset current signal of the current generator.
[0021] For example, the first current signal output by the current generator is a precisely adjustable current source signal used for testing and calibration. The first current signal can be specifically an AC current signal that can be adjusted from 0 to 100A, and has the characteristics of high precision and high stability. It can be applied to the calibration of current transformers and electrical tests.
[0022] Step S102: Control the current processor to receive the second current signal sent by the current transformer; After the current transformer receives the first current signal, the first current signal will generate a second current signal through the current transformer and be output through the current transformer. The second current signal is the feedback current signal after the first current signal passes through the current transformer.
[0023] For example, a current transformer, acting as a feedback element, can proportionally convert a large input current signal (first current signal) into a small input current signal (second current signal).
[0024] The second current signal output by the current transformer will be sent to the current processor. Therefore, it is necessary to control the current processor to receive the second current signal sent by the current transformer.
[0025] For example, the current processor has multiple signal input ports, through which a second current signal sent by a current transformer can be received.
[0026] For example, a current processor may integrate multiple central processing units, consisting of an arithmetic logic unit (ALU), a control unit, and registers.
[0027] For example, the current processor can perform operations such as fetching instructions, executing instructions, and exchanging information with memory and peripherals.
[0028] Step S103: When the current processor receives the first current signal and the second current signal, control the current processor to determine the current difference between the first current signal and the second current signal. The current control processor receives the first current signal and the second current signal respectively.
[0029] For example, the signal input port 1 of the control current processor receives a first current signal, and the signal input port 2 of the control current processor receives a second current signal.
[0030] When the current processor receives the first current signal and the second current signal, it controls the current processor to calculate the difference between the first current signal and the second current signal to obtain the current difference value, wherein the current difference value is the difference between the first current signal and the second current signal.
[0031] For example, the current difference between the first and second current signals can reflect the accuracy of the current processor in processing the current signals. The smaller the current difference, the higher the accuracy of the current processor in processing the current signals. In addition to comparing the current difference, the feedback ripple can also be analyzed to determine whether the waveform is smooth, and abnormal waveforms can be displayed and analyzed. The larger the current difference, the worse the accuracy of the current processor in processing the current signals.
[0032] Step S104: Determine the performance status of the current transformer based on the current difference.
[0033] For example, the current processor can be controlled to determine the performance status of the current transformer based on the current difference, wherein the performance status is used to represent the real-time performance of the current transformer.
[0034] For example, the performance status can be specifically defined as normal performance or abnormal performance.
[0035] For example, abnormal performance of current transformers mainly manifests as increased measurement error, overheating, abnormal noise, and insulation damage, which can lead to equipment burnout or system malfunction in severe cases.
[0036] The control method of the detection device in this embodiment outputs a first current signal to the current transformer through a current generator, and receives the first current signal and the second current signal fed back by the current transformer through a current processor. Based on the current difference between the first current signal and the second current signal, the processing deviation of the transformer for the current signal can be effectively identified, thereby determining the performance status of the current transformer, ensuring the accuracy of performance status identification, and thus improving the detection accuracy of the detection device for the current transformer.
[0037] In some embodiments of this application, a control method for a detection device is provided. After the control current processor determines the current difference between a first current signal and a second current signal, the method further includes: The control current processor sends a first current signal and a second current signal to the waveform analyzer. In this embodiment, the detection device further includes a waveform analyzer, which is used to establish and analyze the waveform of the current signal.
[0038] For example, the waveform analyzer is connected to the third terminal of the current processor via a circuit.
[0039] For example, a waveform analyzer can determine the performance status of a current transformer to enable performance diagnostics of the current transformer.
[0040] The control current processor sends a first current signal and a second current signal to the waveform analyzer, and controls the waveform analyzer to receive the first current signal and the second current signal respectively.
[0041] The control waveform analyzer determines the first signal curve corresponding to the first current signal and the second signal curve corresponding to the second current signal. The waveform analyzer can establish a first signal curve corresponding to the first current signal, wherein the first signal curve is a display curve representing the first current signal.
[0042] The waveform analyzer can also generate a second signal curve corresponding to the second current signal, where the second signal curve is a display curve representing the second current signal.
[0043] For example, the first signal curve and the second signal curve are signal curves in a unified two-dimensional coordinate system.
[0044] The control waveform analyzer displays the first signal curve and the second signal curve respectively.
[0045] For example, the waveform analyzer may include a display screen, through which a first signal curve and a second signal curve may be displayed.
[0046] For example, by displaying the first signal curve and the second signal curve through a waveform analyzer, the numerical difference between the first signal curve and the second signal curve can be visually shown.
[0047] In some embodiments, this application provides a control method for a detection device, wherein a current processor is controlled to determine the current difference between a first current signal and a second current signal, including: The current processor determines the first current signal as the current setpoint. In this embodiment, the control current processor converts the first current signal into a current setpoint, wherein the current setpoint is a theoretical reference value for current comparison.
[0048] For example, by obtaining a preset theoretical conversion ratio and determining the product of the theoretical conversion ratio and the first current signal, the current setpoint can be determined.
[0049] The current processor determines the second current signal as the actual current value. The control current processor converts the second current signal into an actual current value, where the actual current value is the actual feedback current value from the current transformer.
[0050] The control current processor determines the difference between the current setpoint and the actual current value to obtain the current difference.
[0051] In some embodiments of this application, a control method for a detection device is provided, which further includes, when the current processor receives a first current signal and a second current signal: The current processor controls the display of the first current signal and the second current signal, respectively.
[0052] In this embodiment, the current processor may include a screen to display a first current signal and a second current signal, respectively.
[0053] For example, by displaying the first current signal and the second current signal respectively through a current processor, the numerical difference between the first current signal and the second current signal can be displayed intuitively.
[0054] In some embodiments of this application, a control method for a detection device is provided, which determines the performance state of a current transformer based on the current difference, including: If the current difference exceeds the preset current threshold, the performance status is determined to be abnormal. If the current difference is less than or equal to the current threshold, the performance status is determined to be normal.
[0055] In this embodiment, a preset current threshold is obtained, wherein the current threshold is a preset threshold corresponding to the current difference.
[0056] If the current difference is greater than the preset current threshold, it indicates that the current transformer has a large deviation in the feedback of the current signal, and the performance status is determined to be abnormal.
[0057] If the current difference is less than or equal to the current threshold, it indicates that the current transformer has a small feedback deviation to the current signal, and its performance status is determined to be normal.
