Data transmission system and transmission method based on Internet of Things

The invention discloses a data transmission system and method based on the Internet of Things, and belongs to the technical field of data transmission of Internet of Things equipment, and the method comprises the steps that a receiving end of a server receives first collection data distributed from a temporary storage space; establishing a plurality of groups of transmission channels, and determining a communication mode between the transmission channels and the temporary storage space in a first acquisition data transmission process; feeding back the communication mode determined in the transmission process of the first acquisition data to the transmission end in a binary signal mode; the switching frequency in the data transmission process is judged according to the stored binary signals, and the verification mode of the receiving end is selected according to the switching frequency. In the implementation process of the technical scheme of the invention, by establishing multiple groups of transmission chann
