[0014] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0015] The following describes an oscilloscope probe rod, a detection method, an electronic device, and a storage medium according to embodiments of the present disclosure with reference to the accompanying drawings.

[0016] Figure 1 : is a structural block diagram of an oscilloscope probe rod provided according to an embodiment of the present disclosure, such as Figure 1 As shown, the oscilloscope probe rod may include a signal acquisition module, a microcontroller and a signal light feedback module.

[0017] Among them, the signal acquisition module is used to collect the electrical signal of the target object; The microcontroller is used to generate a waveform diagram of the electrical signal and perform waveform analysis on the waveform diagram using the amplitude and frequency of the waveform in the waveform diagram to obtain an analysis result; the analysis result may be any of the following types: abnormal waveform, normal waveform, voltage overload; The signal light feedback module is used to adjust the lighting state of the signal light according to the analysis result; the lighting state is used to indicate the type of the analysis result.

[0018] It should be noted that waveform abnormality means that there is 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; normal waveform can mean 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, that is, the peak in the waveform (which can be a positive peak, a negative peak, or both) no longer presents its original shape (such as the smooth top of a sine wave, the flat top of a square wave), but the peak position and its neighborhood become a horizontal straight line. In this case, the analysis result is determined to be voltage overload.

[0019] In some embodiments of the present disclosure, the analysis results may also include electrical signal failures, which may refer to an obviously unreasonable waveform, such as a waveform with obvious mutations, or only showing a horizontal straight line, or only showing a single point.

[0020] In the embodiment of the present disclosure, a microcontroller is used to perform waveform analysis on the waveform graph using the frequency and amplitude of the waveform, and a signal light is used to indicate whether the waveform corresponding to the collected signal is abnormal and whether the voltage is overloaded. This allows the user 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 after obtaining it to determine whether the waveform meets expectations, effectively improving detection efficiency and user experience.

[0021] As an example, the signal acquisition module can include a high-bandwidth probe front-end circuit for real-time acquisition of electrical signals from the target object. Furthermore, the signal acquisition module can utilize a high-precision attenuation circuit (e.g., switchable 1:10 / 1:100), with an input impedance greater than or equal to 10MΩ and a bandwidth ≥ 200MHz to ensure signal fidelity. The probe front end can also integrate an overvoltage protection circuit (e.g., a TVS diode + resettable fuse) to withstand transient surge voltages of ±100V.

[0022] 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, PLC controller.

[0023] The collected electrical signal is amplified by the low-noise instrumentation amplifier in the signal acquisition module, and then passed through a fourth-order Butterworth filter (the cutoff frequency can be 250MHz) to eliminate high-frequency noise, and then input into a 16-bit high-speed ADC (the sampling rate can be 2GS / s) for digitization.

[0024] In one embodiment, the probe of the signal acquisition module can adopt gold-plated contacts and shielded coaxial structure to reduce contact resistance and electromagnetic interference, with a signal-to-noise ratio of ≥70dB, which can adapt to weak signals and high-precision measurement scenarios.

[0025] As an example of a possible implementation, the microcontroller may 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, capable of real-time signal processing.

[0026] In the embodiment of the present disclosure, the signal acquisition module transmits the collected electrical signal of the target object to the microcontroller. The microcontroller generates a waveform diagram based on the received electrical signal, and uses the frequency and amplitude of the waveform in the waveform diagram to analyze the waveform diagram, that is, to determine whether the waveform in the waveform diagram meets the actual needs, and obtain the analysis result. According to the mapping relationship between different preset analysis results and the lighting state of the traffic light, the lighting state of the traffic light corresponding to the currently obtained analysis result can be determined, thereby controlling the traffic light to light up according to the lighting state.

[0027] In some embodiments of the present disclosure, the signal light may be a red and green dual-color chip LED, which is controlled by a constant current drive circuit and receives instructions (i.e., lighting status) issued by a microcontroller through an SPI interface.

[0028] In addition, as an example, the scattering coating of the red and green dual-color SMD LED can be set to a 120° viewing range, can be set to 8 levels of adjustable brightness, power consumption is less than 50mW, and can be set to an independent power supply to avoid interference, ensuring the reliability of real-time feedback.

[0029] In some embodiments of the present disclosure, Figure 2 As shown, the signal light 2 can be installed on the housing 1 of the oscilloscope probe, so that the user can see the lighting status of the signal light 2 in time.

[0030] In some embodiments of the present disclosure, the microcontroller includes: An acquisition module is used to obtain the amplitude and frequency of the waveform in the waveform graph; A similarity comparison module is used to compare the waveform with a preset waveform to obtain a similarity value; The determination module is used to determine the analysis result of the waveform according to the amplitude, frequency and similarity value.

[0031] In one embodiment, the acquisition module can calculate the signal frequency components based on a Fast Fourier Transform (FFT), that is, converting the time-domain signal into the frequency domain to obtain the amplitude of each frequency component. Furthermore, because the electrical signal is continuously acquired, the acquisition module can employ a sliding window integration method to obtain the dynamic amplitude. This involves segmenting the continuous signal and weighting the frequency-domain energy within the sliding window, thereby dynamically tracking changes in the frequency components and obtaining the dynamic amplitude.

[0032] In one embodiment, a similarity comparison module can be used to compare the waveform with a preset waveform to obtain a similarity value. In addition, a dynamic time warping algorithm can be used to improve the distortion tolerance during the similarity comparison process, that is, the dynamic time warping algorithm can be used to make the waveform as consistent as possible with the preset waveform to obtain the maximum possible similarity.

[0033] In the embodiment of the present disclosure, the three factors of amplitude, frequency and similarity are integrated to analyze the waveform, thereby improving the accuracy of the waveform analysis.

[0034] As an example, the preset waveform may be a square wave or a sine wave.

[0035] In some embodiments of the present disclosure, The signal light feedback module includes: an adjustment submodule, configured to adjust the lighting state of the signal light to a first state if the analysis result indicates a normal waveform, to adjust the lighting state of the signal light to a second state if the analysis result indicates an abnormal waveform, and to adjust the lighting state of the signal light to a third state if the analysis result indicates a voltage overload; A signal light is used to light up according to the lighting state.

[0036] In the disclosed embodiment, the lighting status of the signal lights corresponding to different analysis results can be pre-set, so that the user can know the analysis results only based on the lighting status of the signal lights, and quickly and intuitively understand whether the collected waveform meets expectations, thereby reducing the time for manual judgment.

[0037] In one embodiment, when the analysis result shows that the waveform is normal, the light state of the control signal light is solid green; when the analysis result shows that the waveform is abnormal, the light state of the control signal light is solid red; when the analysis result shows voltage overload or electrical signal failure (that is, the waveform is obviously unreasonable, for example, there is an obvious mutation in the waveform, only a horizontal straight line is displayed, or only a single point is displayed), the light state of the control signal light is flashing red.

[0038] In some embodiments of the present disclosure, the determination module includes: a calculation submodule, configured to calculate a first difference between the amplitude and a preset amplitude, a second difference between the frequency and a preset frequency, and a third difference between the similarity value and a preset similarity value; The determination submodule is used to determine that the analysis result is a waveform abnormality when the first difference does not fall within the first threshold interval, and / or when the second difference does not fall within the second threshold interval, and / or when the third difference does not fall within the third threshold interval.

[0039] In the embodiment of the present disclosure, when the first difference between the amplitude and the preset amplitude does not fall within the first threshold interval, it means that the deviation between the amplitude and the expected amplitude is large; when the second difference between the frequency and the preset frequency does not fall within the second threshold interval, it means that the deviation between the frequency and the expected frequency is large; when the third difference between the similarity value and the preset similarity value does not fall within the third threshold interval, it means that the deviation between the similarity value and the expected similarity value is large.

[0040] Therefore, when the first difference does not fall within the first threshold interval, and / or the second difference does not fall within the second threshold interval, and / or the third difference does not fall within the third threshold interval, the analysis result is determined to be a waveform abnormality.

[0041] In the embodiment of the present disclosure, the user may set the first threshold interval, the second threshold interval, and the third threshold interval in advance according to actual needs.

[0042] It can be understood that by setting an adjustable tolerance range (i.e., the first threshold interval, the second threshold interval, and the third threshold interval), for example, setting a tolerance range of ±1%, ±5%, or ±10%, the oscilloscope probe rod can adapt to different application scenarios, and can also reduce the impact of environmental noise, temperature drift, or measurement errors on electrical signals, and use the tolerance range as a "buffer" to avoid misjudging benign fluctuations as abnormal conditions.

[0043] The oscilloscope probe shown in the embodiment of the present disclosure includes a signal acquisition module, a microcontroller, and a signal light feedback module, wherein the signal acquisition module is used to acquire the electrical signal of the target object; the microcontroller is used to generate a waveform diagram of the electrical signal and perform waveform analysis on the waveform diagram using the amplitude and frequency of the waveform in the waveform diagram to obtain an analysis result; and the signal light feedback module is used to adjust the lighting state of the signal light according to the analysis result. The microcontroller in the oscilloscope probe is used to analyze the waveform diagram of the electrical signal of the target object, and the signal light is controlled to adjust the lighting state according to the analysis result, so that the user can quickly and intuitively know whether the collected electrical signal waveform meets the expectations according to different lighting states, without having to frequently check the oscilloscope screen, thereby improving measurement efficiency.

[0044] Based on the previous embodiment, the present disclosure further provides a possible implementation of an oscilloscope probe rod. Figure 3 This is a structural block diagram of another oscilloscope probe provided by an embodiment of the present disclosure. Figure 1 Based on the oscilloscope probe rod shown, the oscilloscope probe rod further includes: a pressure sensor module 104 .

[0045] The pressure sensor module 104 is used to obtain a first pressure value; the first pressure value is the pressure exerted by the object on the pressure sensor module; The microcontroller 102 includes a control submodule 1021 for controlling the start and stop state of the signal acquisition module according to the first pressure value, and controlling the oscilloscope connected to the oscilloscope probe to display the waveform in a display mode matching the pressure.

[0046] In one embodiment, when the user uses the oscilloscope probe to detect the target object, the user holds the oscilloscope probe and applies pressure to the pressure sensor module installed on the housing of the oscilloscope probe. The stop and start state of the signal acquisition module is controlled by the magnitude of the applied pressure, and the oscilloscope is controlled to display the waveform in a display mode matching the pressure, thereby enabling the user to flexibly and conveniently control the oscilloscope to detect the target object, thereby improving the user experience.

[0047] In some embodiments of the present disclosure, Figure 2 As shown, the pressure sensor module may include an annular pressure group array 3, which is sleeved on the outside of the housing 1 of the oscilloscope probe rod and connected to the microcontroller.

[0048] In the embodiment of the present disclosure, the annular pressure group array is used as a pressure sensor and is mounted on the outside of the oscilloscope detection rod, which can effectively increase the pressure monitoring area, that is, increase the area where the user can apply pressure, so that the user does not need to pay too much attention to finding the location of the pressure sensor during the detection process, thereby improving the detection efficiency.

[0049] In some embodiments of the present disclosure, the control submodule is specifically configured to: Determining a pressure interval to which the first pressure value belongs, and a target stop / start state and a target display mode corresponding to the pressure interval; The control signal acquisition module performs the stop and start operation of signal acquisition according to the target stop and start state; The oscilloscope is controlled to display the waveform according to a target display mode; the display mode is any one of pausing the waveform, freezing the waveform, and updating the waveform.

[0050] In one embodiment, multiple pressure intervals can be pre-set, as well as mapping relationships between the multiple pressure intervals and the start / stop states of the pressure sensor and the waveform display mode. After obtaining a first pressure value collected by the pressure sensor, the target start / stop state and target display mode matching the first pressure value are determined based on the mapping relationships.

[0051] 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 >500g is heavy pressure. When the first pressure value falls into the third pressure range, the waveform is updated, and the pressure grading error is less than 5%.

[0052] In an embodiment of the present disclosure, pausing the display of the waveform graph may mean that when the first pressure value falls into the first pressure interval, the pressure sensor module stops collecting pressure values, and the waveform graph is not displayed on the display screen of the oscilloscope; freezing the waveform graph may mean that when the first pressure value falls into the second pressure interval, the waveform graph on the display screen of the oscilloscope remains in the current state and no longer changes; updating the waveform graph may mean that when the first pressure value falls into the third pressure interval, the pressure sensor module continues to collect pressure values, and the waveform graph updated according to the real-time collected pressure value is displayed on the display screen of the oscilloscope.

[0053] In the embodiment of the present disclosure, the user can flexibly control whether the signal acquisition module collects signals by applying different pressures to the pressure sensor, and can also flexibly control the oscilloscope to display the waveform, thereby improving the convenience and flexibility of detection and enhancing the user experience.

[0054] In some embodiments of the present disclosure, Figure 4 As shown, a signal acquisition module can be used to collect the electrical signal of the target object and send the electrical signal to a waveform analysis module in the microprocessor. The waveform analysis module generates a waveform graph based on the electrical signal and compares and analyzes the waveform graph with the preset waveform graph in the preset waveform module to obtain an analysis result. The LED feedback module is controlled to light up based on the analysis result. When the analysis result shows that the waveform is abnormal, the LED can be controlled to light up red. When the analysis result shows 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 collects 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 size 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 graph is updated based on the real-time collected electrical signal.

[0055] In order to clearly illustrate the above embodiment, the present disclosure provides a detection method of an oscilloscope probe rod. Figure 5 A schematic flow chart of a detection method using an oscilloscope probe rod according to an embodiment of the present disclosure.

[0059] In some embodiments of the present disclosure, determining the analysis result of the waveform graph according to the amplitude, frequency, and similarity value in step 502 may include the following steps: Calculating a first difference between the amplitude and a preset amplitude, calculating a second difference between the frequency and a preset frequency, and calculating a third difference between the similarity value and a preset similarity value; When the first difference does not fall within the first threshold interval, and / or the second difference does not fall within the second threshold interval, and / or the third difference does not fall within the third threshold interval, the analysis result is determined to be a waveform abnormality.

[0060] This embodiment also provides a possible implementation of the detection method of an oscilloscope detection rod. Figure 6 A schematic flow chart of another detection method using an oscilloscope probe rod provided in an embodiment of the present disclosure.
