After the server obtains the number of the receiving ends and the number of the acquisition ends in the graph transmission system, the acquisition ends corresponding to the receiving ends are determined based on the number of the receiving ends and the number of the acquisition ends.
Specifically, if the number of the acquisition ends is an integral multiple of the number of the receiving ends, it is determined that the number of the acquisition ends corresponding to each receiving end is an integral multiple.
For example: the number of the acquisition ends is 4, and the number of the receiving ends is 2, so that the number of the acquisition ends is 2 times of the number of the receiving ends, and the number of the acquisition ends corresponding to each receiving end is determined to be 2.
If the number of the acquisition ends is not an integral multiple of the number of the receiving ends, the number of the acquisition ends corresponding to one receiving end is determined to be a quotient plus remainder value, and the number of the acquisition ends corresponding to other receiving ends is determined to be a quotient value.
