[0074] Adjusting the position of the transmission component based on the offset between the first reference point and the second reference point includes: compensating the initial transmission position with the offset to obtain the target transmission position.

[0075] Specifically, the compensation includes summing the offset with the initial transmission position.

[0076] When the offset between the first reference point and the second reference point is less than or equal to the offset threshold, it is determined that the first reference point and the second reference point are aligned. When the offset between the first reference point and the second reference point is greater than the offset threshold, it is determined that the first reference point and the second reference point are not aligned. If the first reference point and the second reference point are aligned, the initial transmission position is the target transmission position and no correction is required. If the first reference point and the second reference point are not aligned, the initial transmission position needs to be compensated.
