Embodiment Construction

[0020] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present invention, and all similar methods, structures and similar changes of the present invention should be included in the scope of protection of the present invention.

[0021] In the method for measuring the dynamic inclination of an object provided by the embodiment of the present invention, the acceleration components on the X and Y axes are sensed by a cheap MEMS (micro-electromechanical system) accelerometer ADXL202E. The change of the inclination angle is calculated by a certain algorithm. The specific calculation method is as follows: when the object is swaying, there is a dynamic acceleration and a static acceleration (the component of the acceleration of gravity) on the inclined axis. Taking the object swinging around the X-axis at an angular velocity of 15° / s as an example, the d...

Abstract

The invention discloses an object dynamic angle measure method and its device, involving in measurement technology; the resolved measurement technology is the measure of the object dynamic angle; the measurement as the following step: 1) dynamic measure the acceleration: using the acceleration indicator to dynamic measure the acceleration weight aX, aY of X-axis, Y-axis; 2) wireless transmission test data; using the RF transmitter and RF receiver module to test data - the wireless transmission of the acceleration weight aX, aY; 3) computing the dynamic angle of object: the dynamic deviation angle of the object round X-axis: theta x = 5.8480ay-0.4006r; dynamic angle of the object around Y-axis: theta y = 5.8480ax-0.4006r. The invention has low cost, long transmission distance, and can solve the test problem of the object dynamic angel by measure of the acceleration and can real-time wireless measure the dynamic angel of the scene object.

Description

technical field [0001] The invention relates to measurement technology, in particular to a technology for measuring a dynamic inclination angle of an object and its device. Background technique [0002] In many engineering fields, it is necessary to monitor the tilt angle of objects, such as the swing of ship-borne equipment under the action of waves, the swing of high-rise buildings under the action of wind, the swing of manipulators, and the tilt of precision mechanical motion tables under environmental vibrations. At present, inertial gyroscopes or optical systems based on the Doppler effect are mostly used to measure the dynamic inclination of objects. However, the price of the gyroscope is more expensive, the optical system requires more auxiliary equipment, and the test cost is higher. In addition, it is also very necessary to transmit the measurement data to the notebook computer in the form of wireless communication when personnel are not suitable to stay for a long...
