3. the magnetic data of node usage record carries out Ellipse Matching scheduling algorithm analysis, calculates and need to sense magnetic force
Device reads modified parameter.Inside these reference records to intelligent node.
Calibration is had been completed at this time, and the reading of follow-up magnetometric sensor needs after correcting, then is input to
SensorFusion, to calculate accurate exercise data.
Calibration magnetometric sensor also has other methods, mainly there is mutation in step 1 and step 2.It uses in step 1
Different movement/spinning solutions, such as figure of eight shape is drawn in space with node, purpose is provided to measure the magnetic force on periphery
Distributed data；Such as in step 2, using other algorithms, such as average is calculated, is provided to calculate to magnetometric sensor
How reading is corrected.Here it is not required to list one by one.
And the body sensor network of maximum 18 nodes is used in Motionbit intelligence training systems.It is using
Before, it is painful and troublesome for users if carrying out calibration magnetometric sensor one by one to 18 nodes according to the method described above
Process.

2。
The box body 1 does not influence to calibrate without the component for influencing magnetic field.
Have at regular intervals between the card slot 2, avoids adjacent intelligent node electric effect.
The magnetic alignment method of charging box is stored using body sensor network intelligent node of the present invention, steps are as follows：
Step 1, it would be desirable to which the intelligent node of calibration is placed into the card slot 2 of the storage charging box；
Step 2, the storage charging box is rotated respectively one week, each intelligent node on orthogonal 3 axis in space
The measured magnetic data of record；
Step 3, rotation finishes, and each intelligent node calculates the amendment of magnetometric sensor according to the magnetic data of record
Parameter simultaneously preserves.
Compared with prior art, multiple nodes can be all received into box by the present invention, box can to intelligent node into
Row charging, extends the cruise duration of intelligent node.Meanwhile when calibrating magnetometric sensor, it is only necessary to the phase by box in space
It mutually rotates a circle respectively in 3 vertical axis directions, so that it may to be completed at the same time calibration magnetometric sensor to each node, facilitate height
Effect.
