Technical Field

The invention relates to the field of data transmission, in particular to a method and a system for automatically scheduling channels and transmitting tasks based on radio frequency transmission.

Background

The channels used in the transmission of the radio frequency signals are fixed, and each channel is responsible for the fixed content of the transmission.
