[0014] The test method, device and storage medium of the pressure sensing device involved in the embodiment of the present invention establish communication between the pressure device, the pressure sensing device and the calibration device; send a calibration instruction to the pressure sensing device through the calibration device to control the calibration device to perform a calibration operation on the pressure sensing device to obtain calibration information; control the pressure device to apply a test pressure to the pressure sensing device, and obtain the test result of the pressure sensing device according to the reading, test pressure and calibration information of the pressure sensing device; if there is an abnormality in the test result, re-execute the calibration instruction to obtain updated calibration information. By re-executing the calibration instruction according to the test result of the pressure sensing device to obtain updated calibration information, the calibration operation of the test process can be flexibly adjusted to improve the test accuracy and test efficiency of the pressure sensing device.

[0015] Pressure-sensitive devices are devices made using the piezoelectric effect of materials. The structure of most piezoelectric devices consists of electrodes, piezoelectric sheets, brackets and shells. The piezoelectric sheets can be in the shape of discs, long strips, rods, cylinders and the like. Piezoelectric devices have a wide range of applications. When the frequency of the electrical signal is close to the natural frequency of the piezoelectric sheet, the piezoelectric device generates mechanical resonance by the inverse piezoelectric effect. The resonant frequency is mainly determined by the size and shape of the piezoelectric sheet. Many styluses on the market are equipped with pressure-sensitive devices so that the touch device can obtain the pressure applied by the stylus to the touch device, thereby adjusting the thickness of the stylus' handwriting. In order to ensure the quality of the stylus, the pressure-sensitive device needs to be accurately tested. However, different products and pressure-sensitive devices have differences in parameters such as writing pressure and swing amplitude. The pressure-sensitive devices of different products need to be calibrated according to actual conditions before testing.

[0016] At present, the existing pressure sensing device testing methods all need to perform calibration operations in another process before testing, and cannot flexibly adjust the calibration parameters of the test process according to the test results, which affects the test efficiency of the pressure sensing device.

[0017] Based on the above, the embodiments of the present invention provide a test method, device and storage medium for a pressure-sensitive device, by establishing communication between a pressure device, a pressure-sensitive device and a calibration device; sending a calibration instruction to the pressure-sensitive device through the calibration device to control the calibration device to perform a calibration operation on the pressure-sensitive device to obtain calibration information; controlling the pressure device to apply a test pressure to the pressure-sensitive device, and obtaining a test result of the pressure-sensitive device based on the reading, test pressure and calibration information of the pressure-sensitive device; and re-executing the calibration instruction in case of an abnormality in the test result to obtain updated calibration information. By re-executing the calibration instruction according to the test result of the pressure-sensitive device to obtain updated calibration information, the calibration operation of the test process can be flexibly adjusted to improve the test accuracy and test efficiency of the pressure-sensitive device.

[0018] See also Figure 1 , Figure 1FIG. 2 shows the process of the method for testing a pressure sensing device provided by an embodiment of the present invention. Figure 1 As shown, the test method of the pressure sensing device according to the embodiment of the present invention comprises the following steps: Step S1000: establishing communication between the pressure device, the pressure sensing device and the calibration device.

[0019] It is understandable that the pressure device is used to apply a preset test pressure to the pressure-sensitive device so that the pressure-sensitive device can operate stably under the test pressure to improve the accuracy of the test. Specifically, the pressure device can use air pressure, hydraulic pressure, etc. to accurately apply pressure to the pressure-sensitive device to achieve the goal of accurate testing.

[0020] It can be understood that pressure sensing, or pressure induction, refers to the ability of the chip on the digital board to sense the applied pressure and convert it into a signal to transmit to the computer. By simulating the writing and drawing effects under different pressures, pressure sensing technology can present more realistic and natural works on the screen. Therefore, in order to enable the pressure sensing device to be accurately tested, pressure calibration is required. Specifically, pressure calibration refers to ensuring the accuracy and reliability of pressure measuring equipment through certain methods and steps. The importance of pressure calibration lies in ensuring the accuracy of measurement data and avoiding safety problems or economic losses caused by measurement errors. Multiple factors need to be considered during the calibration process, including the selection of pressure media, pollution control, height difference, etc., to ensure the accuracy of the calibration results. In practical applications, the purpose of pressure calibration is to compare the measurement standards, evaluate the indication error of the measuring device, and ensure the accuracy of the measurement value. It is a set of operations for bottom-up measurement traceability. This evaluation of the indication error should be made in accordance with the organization's calibration procedures, carried out according to the calibration cycle, and calibration records and calibration marks should be kept. In addition to evaluating the indication error of the measuring device and determining the relevant metrological characteristics, the calibration results can also be expressed as correction values ​​or calibration factors to specifically guide the operation of the test process of the pressure sensing device. ‌

[0021] See also Figure 2 , Figure 2 FIG. 5 is a schematic diagram showing a specific implementation process of another embodiment of the above step S1000. Figure 2 As shown, step S1000 at least includes the following steps: Step S1100: establishing a connection between the pressure device and the pressure sensing device so that the pressure device applies a test pressure to the pressure sensing device.

[0022] It is understandable that in order for the pressure device to accurately apply the test pressure to the pressure sensing device, the pressure sensing device needs to be stably installed at the output end of the pressure device so that the pressure device can press the pressure sensing device onto the test plane according to the preset test pressure. In practical applications, establishing a connection between the pressure device and the pressure sensing device so that the pressure device applies the test pressure to the pressure sensing device belongs to the prior art and will not be elaborated here.

[0023] Step S1200: establishing communication between the pressure sensing device and the calibration device so that the calibration device sends an instruction for performing a calibration operation to the pressure sensing device.

[0024] It is understandable that communication is established between the pressure sensing device and the calibration device so that the calibration device can accurately calibrate the pressure sensing device. Specifically, the calibration device sends a lot of register configurations to the pressure sensing device, including register addresses and register values, to establish communication between the pressure sensing device and the calibration device to convert and send data to the pressure sensing device.

[0025] In some embodiments, the pressure sensing device and the calibration device are connected via an Inter-Integrated Circuit (I2C), which is a serial communication bus that uses a multi-master-slave architecture. The I2C bus uses the fewest signal lines among various buses and has functions such as automatic addressing, multi-host clock synchronization, and arbitration. Therefore, it is very convenient and flexible to design a computer system using the I2C bus, and it is also small in size, so it is widely used in various practical applications. The pressure sensing device and the calibration device are connected via an integrated circuit bus, which effectively ensures the accuracy and timeliness of data transmission between the pressure sensing device and the calibration device.

[0026] Step S2000: Send a calibration instruction to the pressure sensing device through the calibration device to control the calibration device to perform a calibration operation on the pressure sensing device to obtain calibration information.

[0027] It is understandable that there are many methods for pressure calibration, including electrical calibration, mechanical calibration and comparative calibration. The electrical calibration method uses an electronic pressure sensor to calibrate the pressure gauge; the mechanical calibration method uses a standard mechanical pressure source; the comparative calibration method uses another known accurate pressure gauge for calibration. In addition, there are advanced technologies such as digital high-accuracy pressure calibrators, which are suitable for various application scenarios. In the embodiment of the present application, the comparative calibration method is used to calibrate the pressure sensing device.

[0028] See also Figure 3 , Figure 3 FIG. 2 shows a schematic diagram of a specific implementation process of another embodiment of the above step S2000. Figure 3 As shown, step S2000 at least includes the following steps: Step S2100: Control the calibration device to send a calibration request instruction to the pressure sensing device.

[0029] It can be understood that the test device of the pressure sensing device controls the calibration device to send a calibration request instruction to the pressure sensing device. When a confirmation instruction of the calibration request instruction from the pressure sensing device is received, it proves that the test device of the pressure sensing device communicates successfully with the pressure sensing device, so that the pressure sensing device can enter the calibration operation.

[0030] Step S2200: When the calibration device receives a confirmation instruction of the calibration request instruction, a preset calibration pressure is applied to the pressure sensing device.

[0031] It can be understood that when the calibration device receives a confirmation instruction of the calibration request instruction, a preset calibration pressure is applied to the pressure sensing device. Specifically, the preset calibration pressure can be adjusted according to actual usage and product requirements to meet the test accuracy requirements of the pressure sensing device and ensure the accuracy of the calibration information.

[0032] Step S2300: Control the pressure sensing device to confirm the calibration pressure to obtain calibration information.

[0033] It is understandable that the pressure sensing device is controlled to confirm the calibration pressure to ensure the accuracy of the reading of the pressure sensing device. Specifically, the calibration device is set to zero pressure, and the reading of the pressure sensing device is observed to be zero. If there is a deviation, the zero point of the pressure sensing device is adjusted. The calibration device is set to different pressure values, and the reading of the pressure sensing device is observed to be consistent with the calibration pressure. If there is a deviation, the range of the pressure sensing device is adjusted. In some embodiments, multiple pressure points are selected within the range of the pressure sensing device to observe whether the reading of the pressure sensing device changes linearly with the pressure. If there is a nonlinear phenomenon, a linear calibration is performed. Finally, the calibration information is recorded in the calibration record sheet of the pressure sensing device to facilitate recording and searching the calibration information of the pressure sensing device.

[0034] Step S3000: Control the pressure device to apply a test pressure to the pressure sensing device, and obtain a test result of the pressure sensing device according to the reading of the pressure sensing device, the test pressure and the calibration information.

[0035] It is understandable that during the test of the pressure sensing device, the pressure device applies the test pressure to the pressure sensing device so that the pressure sensing device works under the test pressure. The tester can observe the writing effect of the pressure sensing device and combine the reading of the pressure sensing device, the test pressure and the calibration information to accurately obtain the test result of the pressure sensing device.

[0036] See also Figure 4 , Figure 4 FIG. 5 is a schematic diagram showing a specific implementation process of another embodiment of the above step S3000. Figure 4 As shown, step S3000 at least includes the following steps: Step S3100: Obtain the reading of the pressure sensing device to obtain the test data value of the pressure sensing device.

[0037] It is understandable that, during the test process, in order to accurately measure the pressure exerted on the pressure-sensitive device, it is necessary to obtain the current reading of the pressure-sensitive device and obtain the test data value of the pressure-sensitive device.

[0038] Step S3200: Based on the calibration information, obtain the difference between the test data value and the test pressure.

[0039] It can be understood that based on the test data value and calibration information, the pressure value actually applied to the pressure sensing device can be obtained, and by calculating the difference between the pressure value actually applied to the pressure sensing device and the test pressure, the gap between the actual pressure value and the test pressure can be obtained to determine the accuracy of the pressure sensing device and the applicable pressure range.

[0040] Step S3300: compare the difference with a preset pressure threshold, and output the test result of the pressure sensing device.

[0041] It can be understood that by presetting the pressure threshold and comparing the difference between the test data value and the test pressure with the size of the pressure threshold, it is possible to determine whether the reading of the pressure-sensitive device is within the preset error range, and then obtain the test result of the pressure-sensitive device. At the same time, the tester can also determine whether there is an abnormality in the test result by observing whether the pressure-sensitive device has broken lines or ink leakage during the test. Specifically, when the difference between the test data value and the test pressure is greater than the preset pressure threshold, or the pressure-sensitive device has broken lines or ink leakage during the test, the test result of the output pressure-sensitive device is 0, that is, the test result is abnormal; otherwise, the test result of the output pressure-sensitive device is 1, that is, the test result is normal.

[0042] Step S4000: When the test result is abnormal, re-execute the calibration instruction to obtain updated calibration information.

[0043] It is understandable that when the difference between the test data value and the test pressure is greater than the pressure threshold, the actual pressure on the pressure-sensitive device is significantly different from the test pressure, or the actual pressure on the pressure-sensitive device is too small to trigger the pressure-sensitive device normally. At this time, the pressure-sensitive device may have broken lines or ink leakage during writing and drawing, and needs to be recalibrated according to the calibration pressure and test pressure.

[0044] See also Figure 5 , Figure 5 FIG. 4 is a schematic diagram showing a specific implementation process of another embodiment of the above step S4000. Figure 5 As shown, step S4000 at least includes the following steps: Step S4100: When the difference in the test result is greater than the pressure threshold, a calibration instruction is resent to the pressure sensing device through the calibration device.

[0045] It is understandable that when the difference between the test data value and the test pressure is greater than the pressure threshold, it is necessary to re-calibrate according to the size of the test pressure to improve the accuracy of the pressure sensing device reading. Specifically, according to the preset calibration pressure, such as 0g, 15g, 350g, etc., the calibration operation is re-executed so that during the calibration process, the calibration pressure applied to the pressure sensing device is close to or consistent with the test pressure to ensure the calibration accuracy of the calibration device, and a calibration instruction based on the calibration pressure is sent to the pressure sensing device through the calibration device. It is understandable that the calibration process of the calibration device is consistent with the above-mentioned step S2000 and will not be repeated here.

[0046] Step S4200: Control the pressure sensing device to reconfirm the calibration pressure to obtain updated calibration information.

[0047] It is understandable that the pressure sensing device is controlled to confirm the calibration pressure to ensure that the reading of the pressure sensing device for the calibration pressure is more accurate. Specifically, the calibration device is set to zero pressure, and the reading of the pressure sensing device is observed to be zero. If there is a deviation, adjust the zero point of the pressure sensing device. Next, set the calibration device to a specific pressure value, such as 15g, 350g, etc., set the calibration device to a preset calibration pressure or a pressure value close to the preset calibration pressure, and observe whether the reading of the pressure sensing device is consistent with the calibration pressure. If there is a deviation, adjust the range of the pressure sensing device. Finally, record the calibration information in the calibration record sheet of the pressure sensing device to obtain updated calibration information.

[0048] See also Figure 6 , Figure 6 FIG. 2 is a flow chart showing a method for testing a pressure sensing device in another embodiment of the present invention. Figure 6 As shown, the test method of the pressure sensing device in the embodiment of the present application also includes at least the following steps: Step S4300: If the test result is normal, output the test result.

[0049] It is understandable that when the test result is normal, that is, the pressure sensing device does not have any broken lines or ink leakage, and can work stably and accurately under the test pressure, the test result is output externally. Specifically, the test result includes parameters such as the test pressure range and working time of the pressure sensing device for normal operation.
