Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a bioelectric signal acquisition function testing system, device and method. Background Technology

[0002] Typically, before smartwatches and other wearable devices leave the factory, various tests, such as noise tests, are required to test the device's EMG (electromyography) function. The core objective of noise testing is to verify the device's ability to suppress noise, ensure that the ratio of effective signals (such as electromyographic signals) to noise (signal-to-noise ratio, SNR) meets the standard, and prevent noise from masking the true electromyographic signals.

[0003] During the testing process, since the test signals collected by wearable devices are extremely small signals at the microvolt level, they are easily affected by communication signals such as WiFi or Bluetooth around the wearable device, resulting in noise coupling and thus affecting the accuracy of the test results.

[0004] To address the issue of external interference, shielding boxes are currently the primary method used to block external interference signals. However, if wearable devices and testing equipment (such as PCs) communicate via WiFi, WiFi devices (such as WiFi routers) still need to be installed inside the shielding box. Alternatively, if Bluetooth communication is used, Bluetooth broadcast signals still exist, making it impossible to effectively reduce external interference.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments of this application. As used in the specification and appended claims of the embodiments of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in the embodiments of this application refers to and includes any or all possible combinations of one or more of the listed items.

[0053] In EMG functional testing of wearable devices such as smartwatches, noise testing is a core component of signal quality testing, directly determining the accuracy and stability of the device's electromyography (EMG) signal acquisition. EMG signals are weak bio-photoelectric signals at the microvolt level (typically ranging from 10μV to 1mV), highly susceptible to environmental noise interference. The core objective of noise testing is to verify the device's ability to suppress noise in complex environments, ensuring that the ratio of effective signal (EMG signal) to noise (signal-to-noise ratio, SNR) meets standards, preventing interference from masking the true EMG signal. In other words, noise testing ensures EMG signal quality from a noise suppression perspective, and is a fundamental and core aspect of EMG functional testing. The test results directly affect the accuracy of subsequent functions such as motion recognition and muscle fatigue analysis. For example, a substandard noise test may lead to misjudging muscle activity (e.g., misidentifying environmental noise as muscle contraction signals). Therefore, before wearable devices leave the factory, EMG functional testing (especially noise testing) is often required to ensure that the device's signal quality meets design requirements.

[0054] The inventors discovered that since the device under test and the testing device usually communicate via WiFi or Bluetooth, and WiFi and Bluetooth devices typically use omnidirectional antennas, the signal will radiate evenly in all directions. Therefore, during the testing of bioelectric signals such as EMG signals, the WiFi / Bluetooth signal will cover the acquisition position of the test signal (such as noise signal) of the device under test (such as the electrode position), which will cause the WiFi / Bluetooth signal to couple with the test signal, ultimately affecting the accuracy of the test results.

[0055] Based on this, please refer to Figure 1 One embodiment of this application provides a bioelectric signal acquisition function testing system, including: a testing device and a test terminal with bioelectric signal acquisition function;

[0056] The testing device is used to test the terminal under test according to the testing requirements of the bioelectric signal acquisition function;

[0057] The terminal under test is used to acquire test signals in real time and transmit them to the test device in response to the test device's test.

[0058] The testing device and the terminal under test are connected via millimeter-wave communication, and one of them can dynamically adjust the relative direction angle and / or relative distance relative to the other to ensure that the test signal does not exceed the preset test signal threshold.

[0059] Please see Figure 2 One embodiment of this application provides a testing method applied to the above-described testing system, comprising:

[0060] S11. Real-time acquisition of test signals, which are acquired in real time by the terminal under test in response to the test.

[0061] S12. Dynamically adjust the relative orientation angle and / or relative distance between the test device and / or the terminal under test to ensure that the test signal does not exceed the preset test signal threshold.

[0062] It is understood that in this application, the testing device can be any device with command issuance and signal analysis and processing functions, such as a PC, tablet, or smartphone, and there are no specific limitations. The terminal under test can be wearable devices such as smartwatches, monitoring bracelets, and AR / VR devices, or clinical diagnostic devices such as electrocardiographs. Since the bioelectrical signals (such as electromyography signals, skin conductance signals, and electrocardiogram signals) collected by these devices have clear functional testing requirements such as noise, and these weak bioelectrical signals are easily interfered with by wireless WiFi / Bluetooth communication signals, this application can be applied to testing scenarios of various bioelectrical signal acquisition functions.

[0063] Millimeter waves propagate through space as direct waves with narrow beams and excellent directionality (beam angle <10°). If the millimeter-wave communication signal between the test device and the terminal under test (DUT) completely covers the test signal acquisition location on the DUT, it will significantly interfere with the test signal, causing it to become larger. Conversely, if it only partially or completely excludes the test signal acquisition location, it will cause minimal or no interference, ensuring the test signal remains within a reasonable range. Therefore, this embodiment leverages the strong directionality of millimeter-wave communication by dynamically adjusting the relative azimuth angle and / or relative distance between the test device and the DUT to reduce the coverage of the millimeter-wave communication signal on the test signal acquisition location until the acquired test signal does not exceed a preset test signal threshold. This achieves noise reduction, improving the accuracy and efficiency of the test results.

[0064] In one alternative implementation, the testing apparatus may further include: a first millimeter-wave communication unit and a first controller electrically connected;

[0065] The first millimeter-wave communication unit is used to communicate with the terminal under test via millimeter waves; it is also used to execute corresponding dynamic adjustment actions according to the dynamic adjustment instructions of the first controller during the test. The dynamic adjustment instructions include the relative direction angle and / or relative distance of the first millimeter-wave communication unit relative to the terminal under test.

[0066] The first controller is used to acquire test signals in real time and generate dynamic adjustment commands based on the test signals to control the first millimeter-wave communication unit to perform corresponding dynamic adjustment actions until the current test signal does not exceed the preset test signal threshold.

[0067] Understandably, in order to achieve millimeter-wave communication with the test device, the terminal under test includes a second millimeter-wave communication unit, which is wirelessly connected to the first millimeter-wave communication unit.

[0068] In this embodiment, for ease of control, the first millimeter-wave communication unit included in the testing device can perform dynamic adjustment based on the test signal acquired in real time, thereby achieving noise reduction; during this process, the second millimeter-wave communication unit on the terminal under test can remain stationary.

[0069] In another alternative implementation, the terminal under test or the testing device is also used to acquire the RSSI signal between the testing device and the terminal under test in real time.

[0070] The testing device includes: a first millimeter-wave communication unit and a first controller that are electrically connected;

[0071] The first millimeter-wave communication unit is used to communicate with the terminal under test via millimeter waves; it is also used to execute corresponding dynamic adjustment actions according to the dynamic adjustment instructions of the first controller during the test. The dynamic adjustment instructions include the relative direction angle and / or relative distance of the first millimeter-wave communication unit relative to the terminal under test.

[0072] The first controller is used to acquire test signals and RSSI signals in real time, and generate dynamic adjustment commands based on the test signals and RSSI signals to control the first millimeter-wave communication unit to perform corresponding dynamic adjustment actions until the test signal does not exceed the preset test signal threshold and the RSSI signal exceeds the preset RSSI threshold.

[0073] Among them, the RSSI signal, or Received Signal Strength Indicator, is a quantitative indicator of wireless link quality, specifically referring to the energy intensity of the millimeter-wave communication signal received by the device under test or testing equipment.

[0074] In this embodiment, the RSSI signal is used to determine the stability of the wireless communication link between the test device and the terminal under test. If the RSSI is too low, it may lead to communication interruption or data transmission errors, making effective testing impossible. Based on this, this embodiment uses the test signal and RSSI signal as the basis for dynamic adjustment of the relative direction angle and / or relative distance between the device under test or the test device. Specifically, the relative distance can be adjusted first based on the RSSI signal, and then the relative direction angle can be adjusted based on the test signal.

[0075] In practical applications, the test signal can also be combined with other signals as a basis for dynamic adjustment. The specific method can be determined according to the actual application scenario, and this application embodiment does not impose any specific limitations on this.

[0076] Accordingly, for ease of understanding, please refer to Figure 3 and Figure 4 This embodiment provides yet another testing method, including:

[0077] S21. Perform initialization settings.

[0078] In this step, the initialization settings may include:

[0079] Set the initial relative position between the first millimeter-wave communication unit and the terminal under test, such as a relative distance of 5mm, an azimuth angle of 0 degrees, and an elevation angle of 90 degrees.

[0080] Calibrate the actuator of the first millimeter-wave communication unit;

[0081] Establish a mapping relationship between parameters and actual position / angle to facilitate subsequent adjustments;

[0082] The first millimeter-wave communication unit is set to transmit mode so that the test device can continuously send dynamic adjustment commands through the first millimeter-wave communication unit.

[0083] Establish a millimeter-wave communication channel between the testing device and the terminal under test.

[0084] S22. The test terminal side acquires the RSSI signal of the test device in real time, and collects the test signal in real time through the electrodes.

[0085] S23. The testing device acquires the RSSI signal and the test signal in real time and determines whether both meet the corresponding preset conditions. If so, the position is fixed; otherwise, proceed to the next step S24.

[0086] In this step, the preset conditions can be either the RSSI signal exceeding a preset RSSI threshold or the test signal not exceeding a preset test threshold. The preset RSSI threshold and preset test threshold can be flexibly set according to the actual application testing scenario requirements.

[0087] To further improve the accuracy of the judgment, for example, a method for determining whether a test signal does not exceed a preset test threshold may include:

[0088] For the currently acquired test signal, the sliding window and least binary algorithm are first used to optimize the level processing, then the standard deviation is calculated, and then it is determined whether the standard deviation does not exceed the preset test signal threshold. This can remove obvious impurities in the test signal and improve the accuracy of the judgment.

[0089] S24. The testing device generates a dynamic adjustment command, sets the adjustment step size and angle to control the first millimeter-wave communication unit to perform the corresponding dynamic adjustment action, and returns to step S22.

[0090] In this step, dynamic adjustment is performed when at least one of the RSSI signal and the test signal does not meet the preset conditions. For example, an adjustment factor can be generated first based on the current RSSI signal and the current test signal, and then the adjustment step size and angle can be determined according to this adjustment factor to perform gradual dynamic adjustment and improve the adjustment accuracy.

[0091] Specifically, the adjustment factors may include distance step size factor and angle step size factor:

[0092] Adjusted distance step factor = k rssi ×(1-RSSI 当前值 / RSSI 最大值 ),

[0093] Adjusted angle step factor = k noise ×Noise 当前值 / noise 阈值 ,

[0094] adjust_step d = Distance step factor × step d ;

[0095] adjust_step θ =Angle step factor × step θ ;

[0096] Where, k rssi k is the current distance step size factor. noise The current angle step size factor, step d adjust_step represents the current distance step size. d To adjust the distance step size, step θ The current angle step size, adjust_step θ This is the adjusted angle step size.

[0097] In existing Nosie testing solutions, when using communication methods such as WiFi and Bluetooth, interference can occur in the Nosie signal acquisition link, causing glitches in the acquired Nosie signal. Figure 5 As shown. By adopting the millimeter-wave communication and algorithm-optimized positioning scheme provided in this application embodiment, interference from external communication links to small signals can be effectively removed, and glitches in the Nosie signal acquisition process can be eliminated, such as... Figure 6 As shown. In summary, this embodiment can effectively reduce or even eliminate noise spikes in the Nosie signal during the test signal acquisition process, thereby achieving noise reduction.

[0098] In another alternative implementation, please refer to Figure 7 The testing device may also include an integrated equipment board;

[0099] The integrated device board includes: a second controller, and a Pogo / charging module, a signal generation module, and a DAQ data acquisition unit that are electrically connected to the second controller.

[0100] The Pogo / charging module and the signal generation module are electrically connected to the terminal under test; the DAQ data acquisition unit is electrically connected to the signal generation module; and the second controller is also electrically connected to the first controller, the first millimeter-wave communication unit, and the external charger.

[0101] In this embodiment, the second controller on the integrated device board provides unified management and coordination. A signal generator produces signal waveforms, replacing the original signal generating instrument. A DAQ data acquisition unit collects the voltage and current of the signal generator, replacing the externally controlled power supply. A power supply module is provided to power the first millimeter-wave communication unit, and a switching circuit pin is added to control the millimeter-wave signal strength. Based on integrated control, only UART and other control interfaces are provided externally, facilitating external communication management, simplifying the control process, reducing equipment space, and improving testing efficiency.

[0102] In terms of space utilization: the overall size of the integrated equipment board is only 10cm (length) * 12cm (width) * 1cm (height), which can save the space of two instruments (signal generator and signal acquisition unit), making it convenient for deployment and measurement and reducing costs.

[0103] In terms of acquisition efficiency, the DAQ data acquisition unit can return 10,000 data points at once in about 0.8 seconds, reducing the time spent on multiple interactions when acquiring 10,000 data points. Taking the Angell 66319 as an example, the sampling time is about 1.5 seconds. Therefore, it improves testing efficiency in the process of large-scale, multiple measurements.

[0104] The overall testing process is as follows: The first controller initiates a communication command, which wirelessly controls the DUT (Distributed Under Test) to prepare for signal reception via the first millimeter-wave communication unit. The integrated device board, in conjunction with the first controller, dynamically adjusts the direction and position of the first millimeter-wave communication unit to reduce signal interference. Simultaneously, the first controller controls the signal generator to produce a signal waveform and controls the DAQ (Data Acquisition Module) to sample the data from the signal generator. After a set sampling time, the DUT buffers the sampled data. Then, the first controller initiates control, and the integrated device board connects to the first millimeter-wave communication unit, acquiring the sampled waveform data from the DUT via a wireless channel for analysis and processing, thus providing a complete low-interference communication and data acquisition link.

[0105] In summary, this application achieves the following through millimeter-wave short-range directional communication and an integrated equipment board:

[0106] Unshielded anti-interference: It does not rely on a shielding box and uses the physical characteristics of millimeter waves to reduce communication self-interference and mutual interference from the source. At the same time, it further reduces the interference to test signals during communication by dynamically adjusting the relative direction angle and relative distance.

[0107] Integrated and efficient control: The functions of multiple devices are integrated into a single control board and uniformly scheduled through a first controller, which solves the problems of scattered devices and complex coordination in traditional testing, significantly improves testing efficiency, and provides a low-cost and easy-to-deploy testing device.
