Rotating angle measurement apparatus and rotating angle measurement method

Abstract

The invention discloses a device and a method for measuring the angle of rotation. The device for measuring the angle of rotation comprises an inductive ring and a switching value sensor, wherein the inductive ring comprises a plurality of induction zones distributed along the circumferential direction, and the induction zones comprise a switch-off zone and a switch-on zone which are arranged along the circumferential direction; the induction zones of the inductive ring can pass through the induction zones of the switching value sensor sequentially; the switching value sensor can input signals into a controller when the controller performs scanning; the controller can determine the angle of rotation according to changing times of rotation signals; and preferably, the device for measuring the angle of rotation comprises two inductive rings and two switching value sensors, output signals of the two switching value sensors at least comprise three kinds of combinations, and the controller can determine the direction of rotation according to the changing sequence of the combined rotation signals. The device and the method for measuring the angle of rotation are especially applicable to the measurement of the angle of rotation for correlative parts of engineering machinery.

Description

technical field [0001] The invention relates to a rotation angle measurement technology, in particular to a rotation angle measurement device and a rotation angle measurement method. Background technique [0002] The modern industry constantly puts forward requirements for automation and intelligence of mechanical equipment, and the automation and intelligence of mechanical equipment cannot be separated from various sensors. Various parameters of mechanical equipment can be obtained by using various sensors to realize remote control or operation. . In many mechanical equipment, especially in equipment with mechanical arms, such as concrete pump trucks and automobile hoisting machinery, the rotation angle of the turret directly affects the position of the center of gravity of the equipment. Knowing the rotation angle of the turret in time is very important It is of great significance to ensure the safety and smooth operation of mechanical equipment. [0003] In modern mecha...
