Embodiment

[0064] Such as figure 1 As shown in FIG. 1 , it is a schematic flow chart of a method for measuring and warning the angle of space movement in this embodiment. Aiming at the shortcomings of existing angle sensors such as low measurement accuracy, easy wear, and high cost, using the currently relatively mature space motion sensor chip, according to the measured gyroscope data and angular acceleration sensor data through the attitude fusion algorithm, three Axial high-precision deflection angle information. In order to calibrate the consistency of the running speed of large-scale mechanical equipment, or send out early warning and alarm signals for the deflection of the transmission shaft of large-scale machinery. The method comprises the steps of:

[0065] Step 101. On the space motion equipment, store the zero angle when the angle measuring device is installed; receive a running zero setting instruction, and record the corresponding relationship between the setting instructi...

Abstract

The invention provides a method and a system for spatial motion angle measurement and alarming. The method comprises the steps of storing a zero-position angle in mounting an angle measurer; recordinga correspondence between a setting instruction and the zero-position angle; performing attitude fusion on three-axis gyroscope and three-axis acceleration data for obtaining Euler angle data; obtaining real-time angle position data of spatial motion equipment and displaying; when the spatial motion angle data reach or exceed a preset spacing angle threshold, automatically generating alarming information and displaying, generating a propulsion control instruction which changes the spatial motion angle; controlling a propeller to perform spatial propulsion angle changing; generating a propulsion recovering control instruction according to the correspondence between the real-time angle position and the propulsion recovering control instruction; and controlling the propeller of the spatial motion equipment according to the propulsion recovering control instruction for performing spatial propulsion. The method and the system for spatial motion angle measurement and alarming have advantagesof high precision, high interference resistance, low power consumption and high convenience in mounting.

Description

technical field [0001] The invention relates to the technical field of angle measurement, in particular to a method and system for angle measurement and alarm of space movement. Background technique [0002] With the rapid development of space movement, especially flight technology, such as UAV flight technology, the technical requirements of how to control space movement have attracted more and more attention. To control space movement, it is necessary to grasp information such as the angle of space objects in real time. , thus, the angle measurement of space movement has become one of the key technologies of space movement. [0003] The traditional contact angle sensor is generally a potentiometer type, which has the disadvantages of repeated electric shock, poor wear resistance, low precision, high failure rate, poor anti-corrosion ability, and short life. The non-contact angle sensor is generally a heavy hammer photoelectric sensor, which has disadvantages such as low p...
