[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0019] Refer to the following Figure 1 A method for detecting a horizontal plane deflection angle according to some embodiments of the present invention is described.

[0020] like Figure 1 As shown, the first aspect of the present invention provides a method for detecting a horizontal plane deflection angle, comprising: Step 102, fix the angular displacement sensor on a plane to be measured with a rotation axis, so that the angular displacement sensor is parallel to the plane to be measured, the x-axis of the angular displacement sensor is parallel to the rotation axis, the y-axis of the angular displacement sensor is parallel to the rotation axis and points to the side where the rotation axis is located, and the z-axis of the angular displacement sensor points to the direction of gravity acceleration; Step 104, initializing the angular displacement sensor; Step 106, the plane to be measured is rotated by a preset angle through the rotation axis, and the angle sensor obtains a first gravity acceleration component of the y-axis and a second gravity acceleration component of the z-axis; Step 108, obtaining an initial deflection angle based on the first gravity acceleration component and the second gravity acceleration component; Step 110: The data processing host corrects the initial deflection angle to obtain a final deflection angle.

[0021] The present invention provides a method for detecting a horizontal plane deflection angle, such as Figure 2 As shown, first, the angular displacement sensor 1 is fixed on the plane 2 to be measured with the rotation axis 3, so that the angular displacement sensor 1 is parallel to the plane 2 to be measured. At the same time, when the angular displacement sensor 1 is fixed, the directions of the three axes of the angular displacement sensor 1 are set, wherein the x-axis of the angular displacement sensor 1 is parallel to the rotation axis 3, the y-axis of the angular displacement sensor 1 is parallel to the rotation axis 3 and points to the side where the rotation axis 3 is located, and the z-axis of the angular displacement sensor 1 points to the direction of gravity acceleration.

[0022] Then, the angular displacement sensor 1 is initialized, such as Figure 3 As shown, the plane 2 to be measured is rotated by a preset angle through the rotating shaft 3, and the angle sensor obtains the first gravity acceleration component of the y-axis and the second gravity acceleration component of the z-axis.

[0023] Finally, the initial deflection angle is obtained according to the first gravity acceleration component and the second gravity acceleration component, and the initial deflection angle is corrected by the data processing host to obtain the final deflection angle.

[0024] By using the detection method provided by the present invention, the deflection angle can be detected without manual subtraction.

[0025] Specifically, the angle sensor can be sensitive to the direction of gravity.

[0026] Furthermore, in some embodiments of the present invention, the angular displacement sensor 1 is initialized, including: detecting and acquiring an error angle between the plane to be measured 2 and the horizontal plane through the z-axis of the angular displacement sensor 1 .

[0027] In this embodiment, since the initial zero position of the measured plane 2 is not necessarily on the standard horizontal plane, after the angular displacement sensor 1 is installed, the error angle between the measured plane 2 and the horizontal plane can be detected and obtained, which facilitates the subsequent correction of the results and improves the accuracy.

[0028] Furthermore, in some embodiments of the present invention, the initial deflection angle is corrected to obtain a final deflection angle, including: obtaining a final deflection angle based on the initial deflection angle and the error angle.

[0029] In this embodiment, by subtracting the initial deflection angle from the error angle, each time the sensor measures the angle, the data processing host automatically subtracts the error angle to obtain the final deflection angle, thereby improving convenience.

[0030] Furthermore, in some embodiments of the present invention, an initial deflection angle is obtained based on the first gravity acceleration component and the second gravity acceleration component, including: a data processing host divides the first gravity acceleration component and the second gravity acceleration component to obtain the initial deflection angle.

[0031] In this embodiment, the angle is calculated using the first gravity acceleration component and the second gravity acceleration component, which are gravity acceleration components of two different axes. This can avoid the situation where the yOz plane is not strictly parallel to the gravity direction due to installation errors. Assuming that there is an angle β between the yOz plane and the gravity acceleration, at this time a part of the gravity acceleration acts on the x-axis. Using the ratio of the gravity acceleration of the y-axis and the z-axis for calculation will eliminate the influence of the angle β and improve the measurement accuracy and reliability.

[0032] Furthermore, in some embodiments of the present invention, the angular displacement sensor 1 and the data processing host transmit information via a wired manner.

[0033] Furthermore, in some embodiments of the present invention, the angular displacement sensor 1 and the data processing host transmit information wirelessly.

[0034] The second aspect of the present invention provides a computer-readable storage medium, on which programs or instructions are stored.
