[0029] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0030] The following description, with reference to the accompanying drawings, describes an oscilloscope probe, a probe method, an electronic device, and a storage medium according to embodiments of the present disclosure.

[0031] Figure 1 This is a structural block diagram of an oscilloscope probe according to an embodiment of the present disclosure, such as... Figure 1 As shown, the oscilloscope probe may include a signal acquisition module, a microcontroller, and a signal light feedback module.

[0032] Among them, the signal acquisition module is used to acquire the electrical signals of the target object;

[0033] A microcontroller is used to generate waveforms of electrical signals and to perform waveform analysis on the waveforms using the amplitude and frequency of the waveforms to obtain analysis results. The analysis results include any of the following types: waveform abnormality, waveform normality, and voltage overload.

[0034] The signal light feedback module is used to adjust the lighting status of the signal lights based on the analysis results; the lighting status is used to indicate the type of analysis results.

[0035] It should be noted that waveform anomaly refers to a certain degree of deviation between the waveform in the waveform diagram and the expected waveform, and the degree of deviation exceeds the acceptable range; waveform normal means that there is no deviation between the waveform in the waveform diagram and the expected waveform, or the degree of deviation is within the acceptable range; voltage overload means that the peak value in the waveform (which can be a positive peak value, a negative peak value, or both) no longer presents its original shape (such as the smooth top of a sine wave or the flat top of a square wave), but the peak value position and its neighborhood become a horizontal straight line. In this case, the analysis result is determined to be voltage overload.

[0036] In some embodiments of this disclosure, the analysis results may also include electrical signal faults, which may refer to waveforms that are obviously unreasonable, such as waveforms with obvious abrupt changes, or only displaying horizontal straight lines, or only displaying a single point.

[0037] In this embodiment of the disclosure, a microcontroller is used to analyze the waveform graph by utilizing the frequency and amplitude of the waveform, and indicator lights are used to indicate whether the waveform corresponding to the acquired signal is abnormal and whether there is a voltage overload. This allows users to intuitively know whether there is a certain degree of deviation between the waveform detected by the oscilloscope probe and the expected waveform, without having to manually analyze the waveform graph to determine whether it meets expectations. This effectively improves detection efficiency and user experience.

[0038] As an example, the signal acquisition module may include a high-bandwidth probe front-end circuit for real-time acquisition of the electrical signals of the target object. Furthermore, the signal acquisition module may employ a high-precision attenuation circuit (e.g., 1:10 / 1:100 switchable), with an input impedance greater than or equal to 10MΩ, supporting a bandwidth ≥200MHz, and ensuring signal fidelity. The probe front-end may integrate overvoltage protection circuitry (e.g., TVS diode + resettable fuse), capable of withstanding instantaneous ±100V surge voltages.

[0039] The target object includes, but is not limited to, any one of the following types: printed circuit board (PCB), radio frequency module, power adapter, battery management system, engine control unit, and PLC controller.

[0040] The acquired electrical signal is amplified by a low-noise instrumentation amplifier in the signal acquisition module, then passes through a fourth-order Butterworth filter (cutoff frequency can be 250MHz) to eliminate high-frequency noise, and is then input into a 16-bit high-speed ADC (sampling rate can be 2GS / s) for digitization.

[0041] In one embodiment, the probe of the signal acquisition module can adopt a gold-plated contact and shielded coaxial structure to reduce contact resistance and electromagnetic interference, with a signal-to-noise ratio ≥70dB, which can be adapted to weak signal and high-precision measurement scenarios.

[0042] As an example of a possible implementation, the microcontroller could be a high-performance ARM Cortex-M4 microcontroller, equipped with a 32-bit floating-point unit and a single instruction multiple data (SIMD) instruction set, enabling real-time signal processing.

[0043] In this embodiment of the disclosure, the signal acquisition module transmits the acquired electrical signal of the target object to the microcontroller. The microcontroller generates a waveform based on the received electrical signal and analyzes the waveform using the frequency and amplitude of the waveform, that is, it determines whether the waveform in the waveform meets the actual requirements and obtains the analysis result. Based on the preset mapping relationship between different analysis results and the lighting state of the traffic light, the microcontroller determines the lighting state of the traffic light corresponding to the current analysis result, thereby controlling the traffic light to light up according to the lighting state.

[0044] In some embodiments of this disclosure, the signal light may be a red-green dual-color surface-mount LED, controlled by a constant current driving circuit, and receives instructions (i.e., lighting status) from a microcontroller via an SPI interface.

[0045] Furthermore, as an example, the scattering coating of the red-green dual-color SMD LED can be set to a 120° viewing range, can be set to 8 levels of adjustable brightness, has a power consumption of <50mW, can be set to independent power supply to avoid interference, and ensures the reliability of real-time feedback.

[0046] In some embodiments of this disclosure, such as Figure 2 As shown, the indicator light 2 can be installed on the housing 1 of the oscilloscope probe, so that the user can see the lighting status of the indicator light 2 in a timely manner.

[0047] In some embodiments of this disclosure, the microcontroller includes:

[0048] The acquisition module is used to acquire the amplitude and frequency of the waveform in the waveform diagram;

[0049] The similarity comparison module is used to compare the waveform with a preset waveform to obtain a similarity value;

[0050] The determination module is used to determine the analysis results of the waveform based on the amplitude, frequency, and similarity value.

[0051] In one embodiment, the acquisition module can calculate the signal frequency components based on the Fast Fourier Transform (FFT), that is, convert the time-domain signal into the frequency domain and obtain the amplitude of each frequency component. Furthermore, since the electrical signal is continuously acquired, the acquisition module can use a sliding window integration method to obtain the dynamic amplitude. This involves segmenting the continuous signal, weighting the frequency domain energy within the sliding window, and thus dynamically tracking changes in the frequency components to obtain the dynamic amplitude.

[0052] In one embodiment, a similarity comparison module can be used to compare the waveform with a preset waveform to obtain a similarity value. Furthermore, a dynamic time warping algorithm can be employed to improve the distortion tolerance during the similarity comparison process; that is, the dynamic time warping algorithm is used to make the waveform used for the preset waveform as consistent as possible, thereby obtaining the maximum possible similarity.

[0053] In this embodiment of the disclosure, the waveform is analyzed by combining three factors: amplitude, frequency, and similarity, which improves the accuracy of waveform analysis.

[0054] As an example, the preset waveform mentioned above can be a square wave or a sine wave.

[0055] In some embodiments of this disclosure,

[0056] The traffic light feedback module includes:

[0057] The adjustment submodule is used to adjust the lighting state of the signal light to the first state when the analysis result is that the waveform is normal, to adjust the lighting state of the signal light to the second state when the analysis result is that the waveform is abnormal, and to adjust the lighting state of the signal light to the third state when the analysis result is that the voltage is overloaded.

[0058] Traffic lights are used to illuminate according to their status.

[0059] In this embodiment of the disclosure, different signal light illumination states corresponding to different analysis results can be preset, so that users can know the analysis results simply by judging the illumination state of the signal lights, quickly and intuitively understand whether the collected waveforms meet expectations, thereby reducing the time for manual judgment.

[0060] In one embodiment, if the analysis result indicates that the waveform is normal, the indicator light can be kept on green. If the analysis result indicates that the waveform is abnormal, the indicator light can be kept on red. If the analysis result indicates that there is a voltage overload or an electrical signal fault (i.e., the waveform is obviously unreasonable, such as a significant abrupt change in the waveform, displaying only a horizontal straight line, or displaying only a single point), the indicator light can be kept on red and flashing.

[0061] In some embodiments of this disclosure, the determining module includes:

[0062] The calculation submodule is used to calculate the first difference between the amplitude and the preset amplitude, the second difference between the frequency and the preset frequency, and the third difference between the similarity value and the preset similarity value.

[0063] The determination submodule is used to determine the analysis result as waveform abnormal when the first difference does not fall into the first threshold interval, and / or, the second difference does not fall into the second threshold interval, and / or, the third difference does not fall into the third threshold interval.

[0064] In this embodiment of the disclosure, if the first difference between the amplitude and the preset amplitude does not fall within the first threshold range, it indicates that the deviation between the amplitude and the expected amplitude is large; if the second difference between the frequency and the preset frequency does not fall within the second threshold range, it indicates that the deviation between the frequency and the expected frequency is large; if the third difference between the similarity value and the preset similarity value does not fall within the third threshold range, it indicates that the deviation between the similarity value and the expected similarity value is large.

[0065] Therefore, if the first difference does not fall within the first threshold interval, and / or if the second difference does not fall within the second threshold interval, and / or if the third difference does not fall within the third threshold interval, the analysis result is determined to be a waveform abnormality.

[0066] In this embodiment of the disclosure, the user can pre-set a first threshold interval, a second threshold interval, and a third threshold interval according to actual needs.

[0067] Understandably, by setting adjustable tolerance ranges (i.e., the first threshold range, the second threshold range, and the third threshold range), such as ±1%, ±5%, or ±10%, the oscilloscope probe can adapt to different application scenarios. It can also reduce the impact of environmental noise, temperature drift, or measurement errors on electrical signals, using the tolerance range as a "buffer" to avoid misjudging benign fluctuations as abnormal situations.

[0068] The oscilloscope probe shown in this embodiment includes a signal acquisition module, a microcontroller, and a signal light feedback module. The signal acquisition module acquires the electrical signal of the target object. The microcontroller generates a waveform of the electrical signal and performs waveform analysis using the amplitude and frequency of the waveform to obtain analysis results. The signal light feedback module adjusts the lighting state of the signal light based on the analysis results. By using the microcontroller in the oscilloscope probe to analyze the waveform of the target object's electrical signal and control the signal light to adjust its lighting state according to the analysis results, the user can quickly and intuitively determine whether the acquired electrical signal waveform meets expectations based on different lighting states, eliminating the need to frequently check the oscilloscope screen and improving measurement efficiency.

[0069] Based on the previous embodiment, this disclosure also provides a possible implementation of an oscilloscope probe.

[0070] Figure 3 This is a structural block diagram of another oscilloscope probe provided in an embodiment of the present disclosure. Figure 1 Based on the oscilloscope probe shown, the oscilloscope probe also includes a pressure sensor module 104.

[0071] Among them, the pressure sensor module 104 is used to acquire a first pressure value; the first pressure value is the pressure applied to the pressure sensor module by the object;

[0072] The microcontroller 102 includes a control submodule 1021, which controls the start / stop state of the signal acquisition module according to the first pressure value, and controls the oscilloscope connected to the oscilloscope probe to display the waveform in a display mode that matches the pressure.

[0073] In one embodiment, when a user uses an oscilloscope probe to inspect a target object, they hold the oscilloscope probe and apply pressure to the pressure sensor module mounted on the oscilloscope probe housing. The magnitude of the applied pressure controls the start / stop state of the signal acquisition module and controls the oscilloscope to display waveforms in a manner that matches the pressure. This allows the user to flexibly and conveniently control the oscilloscope to inspect the target object, improving the user experience.

[0074] In some embodiments of this disclosure, such as Figure 2 As shown, the pressure sensor module may include a ring pressure array 3, which is sleeved on the outside of the housing 1 of the oscilloscope probe, and the ring pressure array 3 is connected to the microcontroller.

[0075] In this embodiment of the disclosure, the annular pressure array is used as a pressure sensor and is sleeved on the outside of the oscilloscope probe, which can effectively increase the pressure monitoring area, that is, increase the area that the user can apply pressure to, so that the user does not need to pay too much attention to finding the location of the pressure sensor during the testing process, thereby improving the testing efficiency.

[0076] In some embodiments of this disclosure, the control submodule is specifically used for:

[0077] Determine the pressure range to which the first pressure value belongs, as well as the target start / stop status and target display method corresponding to the pressure range;

[0078] The control signal acquisition module performs the stop and start operation of signal acquisition according to the target stop and start state;

[0079] Control the oscilloscope to display waveforms according to the target display mode; the display mode can be any one of the following: pause waveform display, freeze waveform display, or update waveform display.

[0080] In one embodiment, multiple pressure ranges and mapping relationships between these pressure ranges and the on / off states and waveform display methods of the pressure sensors can be preset. After acquiring the first pressure value collected by the pressure sensor, a target on / off state and target display method matching the first pressure value are determined based on the aforementioned mapping relationship.

[0081] For example, the first pressure range of 50-200g is light pressure. When the first pressure value falls into the first pressure range, the waveform display is paused. The second pressure range of 200-500g is medium pressure. When the first pressure value falls into the second pressure range, the waveform is frozen. The third pressure range of >500g is heavy pressure. When the first pressure value falls into the third pressure range, the waveform is updated. The pressure classification error is <5%.

[0082] In this embodiment of the disclosure, pausing the waveform display can mean that when the first pressure value falls into the first pressure range, the pressure sensor module stops collecting pressure values, and the waveform is not displayed on the oscilloscope screen; freezing the waveform can mean that when the first pressure value falls into the second pressure range, the waveform on the oscilloscope screen remains in the current state and no longer changes; updating the waveform can mean that when the first pressure value falls into the third pressure range, the pressure sensor module continues to collect pressure values, and the waveform updated according to the real-time collected pressure values ​​is displayed on the oscilloscope screen.

[0083] In this embodiment of the disclosure, the user can flexibly control whether the signal acquisition module acquires a signal by applying different pressures to the pressure sensor, and can also flexibly control the oscilloscope to display waveforms, thereby improving the convenience and flexibility of the detection and enhancing the user experience.

[0084] In some embodiments of this disclosure, such as Figure 4 As shown, a signal acquisition module can be used to acquire the electrical signal of the target object and send it to the waveform analysis module in the microprocessor. The waveform analysis module generates a waveform diagram based on the electrical signal and compares and analyzes it with the preset waveform diagram in the preset waveform module to obtain the analysis result. Based on the analysis result, the LED feedback module is controlled to light up. Specifically, if the analysis result indicates that the waveform is abnormal, the LED can be controlled to light up red; if the analysis result indicates that the waveform is normal, the LED can be controlled to light up green. The user can manually adjust the position of the probe (i.e., the oscilloscope probe) so that the signal acquisition module continuously acquires electrical signals at different positions of the target object. In addition, the user can apply pressure to the pressure sensor in the pressure control module (i.e., the pressure sensor module) and control the oscilloscope to display the corresponding waveform according to the magnitude of the applied pressure. For example, when the applied pressure is small, the current waveform is saved and displayed; when the applied pressure is large, the waveform diagram is updated based on the real-time acquired electrical signal.

[0085] To clearly illustrate the above embodiments, this disclosure provides a method for probing an oscilloscope probe. Figure 5 This is a schematic flowchart illustrating a detection method for an oscilloscope probe provided in an embodiment of this disclosure.

[0096] Control the traffic lights to illuminate according to their on status.

[0097] In some embodiments of this disclosure, step 502, determining the analysis result of the waveform based on amplitude, frequency, and similarity value, may include the following steps:

[0098] Calculate the first difference between the amplitude and the preset amplitude, calculate the second difference between the frequency and the preset frequency, and calculate the third difference between the similarity value and the preset similarity value;

[0099] If the first difference does not fall within the first threshold interval, and / or if the second difference does not fall within the second threshold interval, and / or if the third difference does not fall within the third threshold interval, the analysis result is determined to be a waveform abnormality.
