Motion amount monitoring method and system based on three-dimensional ball

The invention relates to the technical field of motion parameter monitoring, in particular to a motion amount monitoring method based on a three-dimensional ball, which comprises the following steps: S1, using ball switches: fixing the three-dimensional ball switches (corresponding to an X axis, a Y axis and a Z axis respectively) at proper positions on an animal body, and when the animal moves, enabling the ball to move and triggering a switch signal due to the inertia effect; s2, acquiring a switch signal: acquiring a trigger signal of a ball switch by using a sensor, and determining the starting time and the ending time of animal movement; s3, calculating a speed signal: calculating the movement speed of the animal according to the contact time and distance of the ball and the sensor, and defining and influencing the weight according to the action. According to the method, the motion state, direction and speed of the animal can be quickly and accurately obtained through calculation of the trigger signal an
