[0066] Dynamic angle measuring equipment:
[0067] The dynamic angle measuring device in the embodiments of this application, such as Figure 1 , 2 As shown, including
[0068] A six-axis gyroscope is used to acquire real-time angle data from the device.
[0069] Input unit 01 is used to input the target measurement axis;
[0070] The data processing unit determines the instantaneous angle value, maximum angular displacement, minimum angular displacement, and angle change based on real-time angle data and the target measurement axis.
[0071] Display unit 02 acquires and displays instantaneous angle values, maximum angular displacement, minimum angular displacement, and angle change.
[0072] The housing 03 is equipped with an input unit 01, a six-axis gyroscope, a data processing unit, and a display unit 02.
[0073] The fastener, located on housing 03, is used to fix the device to the object being measured.
[0074] Specifically, to reduce the error in angle measurement caused by the device's own weight, the dynamic angle measuring device is a small, lightweight device. The six-axis gyroscope, input unit 01, data processing unit, display unit 02, and fixing components are all installed in the housing 03, facilitating the fixation of the device to the object being measured during measurement. The six-axis gyroscope and data processing unit are concealed inside the housing 03. Figure 1 and Figure 2 Not shown in the image.
[0075] In this embodiment, the housing 03 is a square housing as an example. As needed, the housing 03 can also be set to other regular or irregular shapes such as a sphere. The fastener is installed on the outer surface of the housing 03 and can be set as a buckle, strap, adhesive, etc. If necessary, an auxiliary component that cooperates with the fastener can also be installed on the object being measured, and then the fastener is connected to the auxiliary component.
[0076] Input unit 01 can use input elements such as buttons, knobs, touch screens, or voice input modules; display unit 02 can use display elements such as LCD screens or digital tubes; data processing unit can use microprocessors such as microcontrollers or embedded chips. The data processing unit, as a control unit, is communicatively connected to the six-axis gyroscope, input unit 01, and display unit 02. It receives real-time angle data measured by the six-axis gyroscope and the target measurement axis input by input unit 02. Based on a preset data processing method, it determines the instantaneous angle value, maximum angular displacement, minimum angular displacement, and angle change, and outputs these values to display unit 02 for display. Details of the preset data processing method are provided later.
[0077] It should be noted that the dynamic angle measuring device has an independent power supply, which can be a rechargeable battery or a storage battery, to power the various electrical components in the device. Furthermore, the input unit 01 also includes a power switch 14 for turning the device's power on and off.
[0078] The dynamic angle measuring device in this embodiment fixes the device to the object being measured and rotates it. The device acquires real-time angle data through a built-in six-axis gyroscope. The user inputs the target measurement axis through the input unit 01. The data processing unit calculates the required angle data based on the real-time angle data and the target measurement axis and displays it. This allows for convenient dynamic angle measurement with high accuracy.
[0079] In one embodiment, such as Figure 1 , 2 As shown, the input unit 01 includes a measurement axis input button 11 and an initialization button 12;
[0080] Measurement axis input button 11 is used to input the target measurement axis;
[0081] The initialization button 12 is used to input an initialization command after the device is fixed on the object being measured. The six-axis gyroscope responds to the initialization command and uses the current state of the device as the initial state.
[0082] Specifically, the target measurement axes are three coordinate axes in a three-dimensional coordinate system based on the shape of the housing 03, namely the X-axis, Y-axis and Z-axis. There are three measurement axis input buttons 12, corresponding to the X-axis, Y-axis and Z-axis respectively. When the user presses the measurement axis input button 12 corresponding to the target measurement axis, the target measurement axis selection signal can be sent to the data processing unit.
[0083] Preferably, the housing 03 is square to facilitate the establishment of a three-dimensional coordinate system and to facilitate the installation of dynamic angle measuring equipment on the object being measured.
[0084] The initialization button 12 is used to determine the initial state. When the user presses the initialization button 12, he / she inputs the initialization command. After receiving the initialization command, the data processing unit takes the current state of the six-axis gyroscope as the initial state and initializes the current angle of the measured object to 0 degrees.
[0085] This application embodiment allows users to customize the initial position by setting an initialization button, which facilitates the reading and calculation of angle data and can also be used to detect the angle value between two specified positions.
[0086] Furthermore, the housing 03 is also provided with a direction indicator 31, such as... Figure 2 As shown, the direction indicator is used to indicate the direction of the coordinate axis, so that when installing the equipment, the measurement axis of the object to be measured can be adjusted to be parallel to the target measurement axis, thus ensuring the accuracy of the angle measurement.
[0087] It should be noted that the direction indicator 31 indicates the direction of at least two coordinate axes.
[0088] In one embodiment, the input unit 01 further includes an angle input button 13 for inputting a compensation angle value;
[0089] Based on real-time angle data and the target measurement axis, determine the instantaneous angle value, maximum angular displacement, minimum angular displacement, and angle change, specifically including:
[0090] The real-time detection angle is determined based on the real-time angle data and the target measurement axis;
[0091] The maximum and minimum angular displacements are determined based on the real-time detection angle.
[0092] The change in angle is obtained by subtracting the minimum angular displacement from the maximum angular displacement and then adding the compensation angle value.
[0093] Specifically, because the object being measured is equipped with a dynamic angle measuring device, the friction increases during rotation, resulting in an angle error. The compensation angle value is the angle value of the error. The compensation angle value is input via the angle input button 13. First, the maximum and minimum angular displacements are determined based on the real-time detected angle. When determining the angle change, in addition to calculating the difference between the maximum and minimum angular displacements, the compensation angle value is added to improve the measurement accuracy of the angle change.
[0094] The angle input button 13 includes eleven buttons, including ten numeric keys from 0 to 9, a confirmation button, and a clear button. The confirmation button is used to send a confirmation command after the compensation angle value is input, and the clear button is used to clear the data for re-entry when the compensation angle value is entered incorrectly.
[0095] The compensation angle value is obtained by the user through measurement and calculation. The specific measurement steps are detailed below.
[0096] As needed, the above technical solutions can be combined to achieve the best technical effect.
[0097] Dynamic angle measurement method:
[0098] The technical solution of this application also provides a dynamic angle measurement method based on the dynamic angle measuring device as described above, such as... Figure 3 As shown, including
[0099] Step S301: Fix the dynamic angle measuring device to the object being measured using fasteners;
[0100] Step S302: Control the rotation of the object under test, and use the six-axis gyroscope to acquire the real-time angle data of the device;
[0101] Step S303: Input the target measurement axis through the input unit;
[0102] Step S304: The data processing unit determines the instantaneous angle value, maximum angular displacement, minimum angular displacement, and angle change based on the real-time angle data and the target measurement axis, and displays them on the display device.
[0103] Taking the measurement of windshield wiper angle as an example, such as Figure 4As shown, the dynamic angle measuring device 001 is fixed to the wiper 002 by a fastener. The measuring axis of the wiper 002 is along the length of the wiper. When fixed, one of the coordinate axes in the preset three-dimensional coordinate system of the dynamic angle measuring device 001 is adjusted to be parallel to the measuring axis of the wiper 002. This coordinate axis is the target measuring axis input in step S303.
[0104] After the dynamic angle measuring device is fixed, turn on the power switch to start the dynamic angle measuring device, and then execute step S302 to control the wiper to start rotating. During the rotation, the six-axis gyroscope records the real-time angle data. After the wiper has been working for a period of time, control the wiper to stop rotating and end the angle data acquisition. After that, the dynamic angle measuring device can be removed from the wiper to perform subsequent steps, or it can be fixed on the wiper to continue performing subsequent steps.
[0105] In step S303, the target measurement axis is input via the measurement axis input button on the input unit. In step S304, after receiving the target measurement axis, the data processing unit determines the instantaneous angle value, maximum angular displacement, minimum angular displacement, and angle change based on the target measurement axis and the real-time angle data measured by the six-axis gyroscope, according to the preset data processing method. The instantaneous angle value, maximum angular displacement, minimum angular displacement, and angle change are then output to the display unit for display, allowing the user to directly read the angle data from the display unit.
[0106] Figure 5 The graph shows the angle change curve of the wiper during rotation. The data processing unit processes the collected real-time angle data. The instantaneous angle value is the current real-time angle value. Then, the maximum and minimum angle values within the collection time are selected as the maximum angular displacement and the minimum angular displacement, respectively. The value of the maximum angular displacement minus the minimum angular displacement is taken as the angle change. Figure 5 The diagram shows two angular change curves for the windshield wipers at high and low speeds. The maximum angular displacement at low speed is α. max,1 The minimum angular displacement is α min,1 The angle change curve is α max,1 -α min,1 When rotating at high speed, the corresponding maximum angular displacement is α. max,2 The minimum angular displacement is α min,2 The angle change curve is α max,2 -α min,2 .
[0107] The dynamic angle measurement method in this application embodiment fixes the dynamic angle measuring device on the object being measured and rotates it. The device collects real-time angle data through a built-in six-axis gyroscope. The user inputs the target measurement axis through the input unit. The data processing unit calculates the required angle data based on the real-time angle data and the target measurement axis and displays it. This method can conveniently measure dynamic angles and has high measurement accuracy.
[0108] In one embodiment, the input unit further includes an initialization button;
[0109] After fixing the device to the object being measured using fasteners, the process also includes...
[0110] Enter the initialization command using the initialization button;
[0111] The six-axis gyroscope responds to the initialization command by taking the current state of the device as the initial state.
[0112] Specifically, the user inputs an initialization command through the initialization button. After receiving the initialization command, the data processing unit takes the current state of the six-axis gyroscope as the initial state and initializes the current angle of the measured object to 0 degrees.
[0113] This application embodiment allows users to customize the initial position after the dynamic angle measuring device is fixed by setting an initialization button, which facilitates the reading and calculation of angle data and can also be used to detect the angle value between two specified positions.
[0114] In one embodiment, the input unit further includes an angle input button for inputting a compensation angle value;
[0115] After the target measurement axis is input through the input unit, it also includes
[0116] Input the compensation angle value through the input unit;
[0117] The data processing unit determines the instantaneous angle value, maximum angular displacement, minimum angular displacement, and angle change based on real-time angle data and the target measurement axis, specifically including:
[0118] The real-time detection angle is determined based on the real-time angle data and the target measurement axis;
[0119] The maximum and minimum angular displacements are determined based on the real-time detection angle.
[0120] The change in angle is obtained by subtracting the minimum angular displacement from the maximum angular displacement and then adding the compensation angle value.
[0121] Specifically, when a dynamic angle measuring device is installed on the object being measured, the friction increases during rotation, resulting in an angle error. The compensation angle value is the angle value of this error. Taking a windshield wiper as an example, without the dynamic angle measuring device, the angle change per rotation cycle is β1. After the dynamic angle measuring device is installed, due to the increased friction, the angle change per rotation cycle decreases to β2. The value of β1 minus β2 is the compensation angle value.
[0122] In this embodiment of the application, an angle input button is set to input the compensation angle value. First, the maximum and minimum angular displacements are determined based on the real-time detected angle. When determining the amount of angle change, in addition to calculating the difference between the maximum and minimum angular displacements, the compensation angle value is added to improve the measurement accuracy of the amount of angle change.
[0123] Figure 6 A flowchart of a dynamic angle measurement method according to a preferred embodiment of this application is shown, including...
[0124] Step S601: Fix the dynamic angle measuring device to the object being measured using fasteners;
[0125] Step S602: Input the initialization command through the initialization button. The six-axis gyroscope responds to the initialization command and takes the current state of the device as the initial state.
[0126] Step S603: Control the rotation of the object under test, and use the six-axis gyroscope to acquire the real-time angle data of the device;
[0127] Step S604: Input the target measurement axis through the input unit;
[0128] Step S605: Input the compensation angle value through the input unit;
[0129] Step S606: Determine the real-time detection angle based on the real-time angle data and the target measurement axis;
[0130] Step S607: Determine the maximum and minimum angular displacements based on the real-time detected angles;
[0131] Step S608: Subtract the minimum angular displacement from the maximum angular displacement, and add the compensation angle value to obtain the angular change.
[0132] Step S609: Display the instantaneous angle value, maximum angular displacement, minimum angular displacement, and angle change on the display device.
[0133] The compensation angle value is measured in the following manner, and the measurement steps include:
[0134] Different weights of counterweights are installed on the dynamic angle measuring device. The corresponding angle change data is measured through the angle change measurement steps, and multiple sets of device weight and corresponding angle change data are obtained.
[0135] The compensation angle value is calculated based on multiple sets of equipment weight and corresponding angle change data.
[0136] The step of measuring the angle change includes:

[0139] Input the target measurement axis through the input unit;
[0140] The data processing unit determines the angle change based on real-time angle data and the target measurement axis and displays it on the display device.
[0141] During the measurement of the compensation angle value, by installing counterweights of different weights on the dynamic angle measuring device, the weight of the device (the weight of the device is the sum of the weight of the bare device and the weight of the counterweights) is changed, and the real-time angle data of the rotating object of the test object for a preset period is measured using the dynamic angle measurement method described in any of the aforementioned embodiments, multiple sets of device weight and corresponding angle change data are obtained, which are used to calculate the compensation angle value.
[0142] Specifically, based on multiple sets of equipment weight and corresponding angle change data, the compensation angle value is calculated, including...
[0143] By fitting multiple sets of equipment weight and corresponding angle change data, a functional relationship between equipment weight and angle error is obtained, specifically including...
[0144] Substitute multiple sets of equipment weight and corresponding angle change data into the following formula to obtain the values of α0 and k;
[0145] α x+1 =k*M x +α0
[0146] Where, α x+1 M represents the angular change, where α0 is the actual angular change of the measured object during a preset rotation period without any equipment. x Where k is the weight of the equipment, and k is a coefficient.
[0147] The functional relationship between equipment weight and angular error is determined as follows:
[0148] Δα x =α x+1 -α0=k*M x
[0149] Where, Δα x This represents the angular error.
[0150] Then, the bare weight of the dynamic angle measuring device is substituted into the function relationship to calculate the corresponding angle error as the compensation angle value.
[0151] This application embodiment obtains the functional relationship between equipment weight and angle error through data fitting, thereby enabling the calculation of the corresponding angle error based on the bare weight of the equipment and obtaining the angle compensation value.
[0152] The above description is merely the principle and preferred embodiment of this application. It should be noted that for those skilled in the art, implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included within the technical scope of this invention. Based on the principle of this application, several other modifications can also be made, which should also be considered within the protection scope of this application.
