Abstract

The invention discloses a magnetic hysteresis compensation method, a storage medium and an intelligent wearable device. The intelligent wearable device comprises a measurement Hall sensor and a compensation Hall sensor in addition to a wearable device body and an earphone. The measurement Hall sensor is arranged at a base and is used for being aligned with a magnet on the earphone, and the compensation Hall sensor is arranged on the wearable device body and is staggered from the magnet on the earphone and used for detecting a magnetic field of an environment where the compensation Hall sensoris located. The measurement Hall sensor and the compensation Hall sensor are both electrically connected with an MCU, the MCU compensates a magnetic field detected by the measurement Hall sensor according to a compensation magnetic field corresponding to an interference magnetic field detected by the compensation Hall sensor, and the compensated magnetic field serves as a basis of detecting an access state of the earphone, so that magnetic hysteresis of the Hall sensors is removed and the accuracy of actual measured values of the Hall sensors is improved.

Description

technical field [0001] The invention relates to the field of magnetic field technology, in particular to a hysteresis compensation method, a storage medium and a smart wearable device. Background technique [0002] Smart wearable devices are widely used in daily life, for example, smart wearable devices may be bracelets, watches, and the like. At present, smart wearable devices can also be combined with earphones to achieve specific functions. For example, a base that can cooperate with earphones (mainly wireless, equipped with a Bluetooth module) is reserved on the wristband to realize functions such as charging the earphones. Commonly known as wrist Bluetooth headset. The above smart wearable devices can not only realize the function of the wristband, but also can be embedded in the earphone, which has more functions. [0003] Take the bracelet as an example. Usually, the bracelet is equipped with a Hall sensor to measure the switch function, specifically to detect the s...
