Embodiments of the present invention provide a rotation angle detection device, method, and electronic equipment, using a Helmholtz coil composed of a first coil and a second coil as a magnetic field excitation source, and the first coil and the second coil are arranged opposite and parallel to the One of the first structural member and the second structural member, the magnetic sensor is arranged on the other of the first structural member and the second structural member, and the magnetic sensor is located between the first coil and the second coil, in the first When the structural member rotates relative to the second structural member along the rotation axis, the magnetic field intensity component on the detection coordinate axis of the magnetic sensor will change accordingly. Therefore, the magnetic field information is collected by the magnetic sensor, and then the rotation angle is determined based on the magnetic field information. The first The magnitude of the current passed into the coil and the second coil is controllable, which can avoid the problem of increasing the calibration frequency due to the degradation of the permanent magnet over time, thereby reducing the magnetic field excitation while ensuring the accuracy of the rotation angle detection Calibration frequency of the source.
Description
technical field [0001] The invention relates to the technical field of mechanical structures, in particular to a rotation angle detection device, method and electronic equipment. Background technique [0002] At present, with the application of mechanical structures with rotary motion (that is, rotating mechanisms) more and more widely, in order to realize the precise control of the operating state of the rotating mechanism during the normal operation of the rotating mechanism, it is necessary to adjust the rotation angle of the rotating mechanism Monitor and control the rotation angle precisely. [0003] At present, the angle detection device of the rotating mechanism is mainly: a permanent magnet of a specific shape is used as the magnetic field excitation source, and a magnetic field detection sensor is added to detect the rotation of the rotating mechanism by detecting the relative positional relationship between the permanent magnet and the magnetic field excitation sou...
