[0013] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0014] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0015] Current sensor sensitivity testing equipment is often bulky and difficult to carry, making it unsuitable for rapid on-site testing. Furthermore, the data transmission of sensitivity testing equipment via cable connections is complex and restricts testing scenarios, especially when physical operations such as vibration or tilting of the sensor are required, as the cables can introduce interference.

[0016] To address the aforementioned technical problems, this embodiment provides a wireless testing method for MEMS sensors. This wireless testing method for MEMS sensors is executed on a mobile terminal, as described above. Figure 1 Specifically, it includes steps S1, S2, S3, S4, S5, S6 and S7.

[0017] The mobile terminal and the MEMS sensor testing equipment are respectively configured with corresponding wireless communication modules, such as Bluetooth modules. The mobile terminal can be a smartphone, tablet computer, etc., as long as it can run programs.

[0018] Step S1: Establish a wireless data transmission channel between the mobile terminal and the MEMS sensor testing equipment via Bluetooth. After the mobile terminal establishes a connection with the MEMS sensor testing equipment, the graphical interface of the mobile terminal will display the text message "Bluetooth connected".

[0019] The mobile terminal and the MEMS sensor testing equipment are wirelessly connected via Bluetooth, allowing the testing process to be completed directly from the mobile terminal. This eliminates the constraints of cables, making sensor testing more flexible and suitable for various complex environments and mobile scenarios. The mobile terminal can be a smartphone or tablet, eliminating the need for dedicated equipment and reducing testing costs and barriers to entry.

[0020] Step S2: Before the MEMS sensor testing equipment starts testing the sensor, test parameters are set remotely for the MEMS sensor testing equipment via a mobile terminal. The MEMS sensor testing equipment then tests the sensor according to the test parameters to obtain the sensor's voltage data.

[0021] The step of remotely setting test parameters for the MEMS sensor testing equipment via a mobile terminal specifically involves: The channel selection parameter is set to determine which one or more sensors to test. In this embodiment, setting the channel selection parameter means setting the number of sensors to be tested. For example, setting the channel selection parameter to 1 means testing one sensor, and setting the channel selection parameter to 2 means testing two sensors simultaneously. By setting the channel selection parameter, it is possible to test multiple channels simultaneously.

[0022] To set the gain adjustment parameters, the acquired sensor signal needs to be amplified during the test. The amplification factor of the sensor signal can be adjusted by setting the gain adjustment parameters. Specifically, you can choose either voltage adjustment gain mode or resistance adjustment gain mode to set the gain adjustment parameters.

[0023] Voltage adjustment gain process: Step 1: Electrothermal conversion, using voltage to control temperature. The sensor has resistance; when voltage is applied to the sensor, current is generated. The current flowing through the resistor generates heat, and the sensor dissipates heat to the surrounding environment while heating. When the heating power equals the heat dissipation power, the temperature stabilizes. One voltage corresponds to one operating temperature.

[0024] The second step: thermal conversion, where temperature changes cause changes in material properties. For example, based on the thermal resistance effect, the resistance of a material changes with temperature.

[0025] Step 3: Signal acquisition, physical changes are converted into electrical signals.

[0026] The sensor is powered on and connected to the reading circuit (e.g., Wheatstone bridge, transimpedance amplifier). When the resistance of the sensor changes with temperature, the current or voltage in the circuit will change accordingly. This changing current or voltage is the final acquired signal, i.e., the gain controlled by voltage.

[0027] Resistor adjustment gain process: In a sensor testing system, signal gain is controlled by adjusting the resistance value. The working principle utilizes the negative feedback mechanism of an operational amplifier. The gain (i.e., amplification factor) of the amplifier is determined by the ratio of its surrounding resistances. Changing the resistance value can precisely change this ratio, thereby amplifying the weak signal from the sensor.

[0028] Most variable gain control circuits are built on operational amplifiers, which have extremely high open-loop gain.

[0029] One of the most typical applications is the in-phase amplifier, whose gain formula is: Formula (1) G is the gain (amplification factor) of the circuit. It is a feedback resistor, connected between the output and inverting input of the operational amplifier. It is the gain setting resistor, connected between the inverting input and ground (or reference point).

[0030] From formula (1), it can be seen that the gain G is related to the resistance. and The ratio is directly related. Therefore, by changing... or The gain of the entire circuit can be adjusted by changing the resistance value.

[0031] The sampling rate parameter is set to determine the frequency at which voltage data from the sensor is collected.

[0032] Step S3: The mobile terminal receives the voltage data of the sensor from the MEMS sensor testing device via the Bluetooth module.

[0033] Step S4: The mobile terminal preprocesses the voltage data of the sensor received from the MEMS sensor testing equipment, and calculates the sensitivity of the sensor currently being tested based on the voltage data. Specifically, this includes: Step S4.1: Perform moving average filtering on the voltage data of the sensor received from the MEMS sensor testing equipment. In order to eliminate high-frequency noise interference, perform moving average filtering on the raw data of the voltage output by the sensor collected within a sliding window according to the following formula (2).

[0034] Formula (2) in, This represents the raw data of the voltage collected from the sensor; Where N is the size of the sliding window, for example, N=10; in, This represents the sensor voltage obtained after performing a moving average filtering process on the raw voltage data of the sensor.

[0035] Step S4.2: Determine the voltage reference value of the sensor.

[0036] The method for determining the voltage reference value of the sensor includes: Method 1: The voltage reference value of the sensor can be calibrated by automatic zero-point calibration. For a sensor under test, when the sensor is in a static state without excitation, the voltage value read by the MEMS sensor testing equipment is used as the voltage reference value. .or, Method 2: Input a known voltage reference value via a mobile terminal. .

[0037] Step S4.3, calculate the sensor sensitivity, specifically: The sensitivity is calculated using the differential ratio method. During the test of the sensor's sensitivity, when the sensor is subjected to external excitation (such as acceleration or pressure change), the sensor voltage changes. First, the change in the sensor's current voltage relative to the voltage reference value is calculated. Then, the ratio of the change to the voltage reference value is the sensor sensitivity, as shown in formula (3).

[0038] Formula (3) in, The voltage of the sensor in its current state; in, The voltage reference value of the sensor; in, It is the change in the sensor's output voltage; Where K is a unit conversion factor, for example, converting the ratio value to mV / g or % . in, It is the calculated sensitivity value of the sensor.

[0039] Step S4.4: Preset the maximum and minimum sensitivity thresholds.

[0040] In this implementation, the maximum and minimum thresholds for the sensor's sensitivity can be set via a mobile terminal.

[0041] The sensor sensitivity is calculated based on the voltage data obtained from the test. It is then determined whether the sensor sensitivity is between the minimum and maximum sensitivity thresholds. If the sensor sensitivity is between the minimum and maximum sensitivity thresholds, the sensor sensitivity meets the requirements, and "qualified" is displayed on the mobile terminal accordingly.

[0042] If the sensor sensitivity is not between the minimum and maximum sensitivity thresholds, the sensor sensitivity does not meet the requirements. In this case, "unqualified" will be displayed on the mobile terminal, and a warning message will be issued. The warning message can be an audio reminder, a text reminder, etc. At the same time, the mobile terminal records the sensor sensitivity value that does not meet the requirements.

[0043] Step S4.5: Display the sensor sensitivity values ​​that meet the threshold requirements.

[0044] By comparing the calculated sensor sensitivity value with the maximum and minimum thresholds of the sensor sensitivity, a sensor sensitivity value that meets the requirements of the maximum and minimum thresholds is determined, and the mobile terminal displays the sensor sensitivity value.

[0045] In this embodiment, the above-mentioned method for calculating the sensitivity of the sensor can be implemented on a mobile terminal through software programming. After the mobile terminal and the MEMS sensor testing equipment establish communication, the mobile terminal can automatically complete the acquisition of the voltage data of the sensor, calculate the sensitivity of the sensor based on the acquired data, and display the sensor sensitivity data in real time. The operation is simple and convenient.

[0046] The mobile terminal preprocesses the voltage data of the sensor received from the MEMS sensor testing equipment, calculates the sensitivity of the sensor currently being tested based on the voltage data, and then includes the following steps: Step S5, visualize the sensor data, specifically including: The multi-channel display method allows for the simultaneous plotting of real-time data curves from multiple sensors based on their voltage data. The real-time data curves are plotted with the sensor voltage data on the vertical axis and the time of reading the sensor voltage data on the horizontal axis.

[0047] Single-channel display mode is used to display real-time data of a single parameter from a single sensor, enabling real-time monitoring of that single parameter. For example, multiple samples can be taken from a single parameter of a sensor, and the multiple sample data can be graphically displayed using single-channel display mode.

[0048] As attached Figure 2 As shown in the attached figure, the curve plotted on the left side uses the sensor's voltage data as the ordinate and the time of voltage reading as the abscissa to plot the sensor's voltage curve. On the right side of the figure, MEMS1...MEMS8 correspond to eight sensors. Selecting one sensor plots its voltage curve on the left side of the graphical interface; selecting multiple sensors plots their voltage curves on the right side of the interface.

[0052] For example, after the mobile terminal and the MEMS sensor testing equipment successfully connect via Bluetooth, the system automatically records a test log, such as "log: Bluetooth connection successful".

[0053] The wireless testing method for MEMS sensors, during the testing process, generates a test log on a mobile terminal, and then includes the following steps: Step S7, data management, specifically includes: During the testing process of the MEMS sensor by the MEMS sensor testing equipment, the mobile terminal can send commands to the MEMS sensor testing equipment to pause or resume the acquisition and display of voltage data from the sensor, realizing real-time control of the voltage data acquisition process. The mobile terminal sends control commands to the MEMS sensor testing equipment wirelessly, making operation simple.

[0054] After completing the testing and plotting of the voltage data of a sensor, before starting subsequent tests, the mobile terminal can send a command to the MEMS sensor testing equipment to clear the currently displayed historical data curve. After completing the subsequent tests, the curve is re-plotted based on the obtained sensor voltage data.

[0055] The mobile terminal can send commands to the MEMS sensor testing equipment to export test data or charts for subsequent analysis. In this embodiment, the test data or charts can be exported in Excel format, which is achieved through software programming.
