Background The electronic equipment falls off when the gyroscope is used, and the electronic equipment can damage working gyroscope components due to collision, so that the gyroscope components are abnormal in function. So in order to avoid damage to the gyroscope caused by the impact of the electronic device, the gyroscope needs to be turned off before the electronic device is impacted, that is, when the electronic device is in the falling process. How to accurately detect the falling process of the electronic equipment becomes the current problem to be solved.

By the above means, the antigravity acceleration, which is small in value when the electronic device is dropped and large in value when the electronic device has supporting force (for example, the electronic device is placed on a table), is accurately determined together by the acceleration in each axis direction and the centripetal acceleration on the coordinate system. Therefore, the falling state of the electronic device can be accurately detected based on the antigravity acceleration. In one possible mode, the method comprises the steps of determining a first acceleration of the electronic equipment in the X-axis direction of the first coordinate system, a second acceleration of the electronic equipment in the Y-axis direction of the first coordinate system, a third acceleration of the electronic equipment in the Z-axis direction of the first coordinate system, a first axial acceleration of an acceleration component in the X-axis direction of the first coordinate system, a second axial acceleration of the acceleration component in the Y-axis direction of the first coordinate system and a third axial acceleration of the acceleration component in the Z-axis direction of the first coordinate system through the acceleration component of the electronic equipment, determining a first acceleration of the electronic equipment in the X-axis direction of the first coordinate system, a second acceleration of the electronic equipment in the Y-axis direction of the first coordinate system and a third acceleration of the electronic equipment in the Z-axis direction of the first coordinate system through the gyroscope component of the electronic equipment, and determining a first axial acceleration of the acceleration component in the X-axis direction of the first coordinate system, a second axial acceleration of the acceleration component in the Y-axis direction of the first coordinate system and a third axial acceleration of the component in the Z-axis direction of the first coordinate system.
