It may be understood that the execution body of the embodiment is a primary gateway device, where the primary gateway device communicates with a data source device, and before sending out data to be transmitted, the data source device detects data amount information of the data to be transmitted, sends the data amount information to the primary gateway device, where the data amount information is used to characterize a data size of the data to be transmitted.
It should be noted that, the size of a transmission data packet supported by a protocol used by the gateway device is preset, the number of enabled gateways is determined according to the data amount information of the data to be transmitted and the size of the transmission data packet supported by the protocol, for example, the data amount information represents that the data size of the data to be transmitted is 32 bits, the size of the transmission data packet supported by the protocol is 16 bits, and the number of enabled gateways is determined to be 2; the data quantity information represents that the data size of the data to be transmitted is 40 bits, the size of a transmission data packet supported by a protocol is 16 bits, and the number of enabled gateways is determined to be 3.
Step S20: and when the residual buffer space of the self-service data transmission system meets the transmission requirement, the self-service data transmission system is communicated with the plurality of slave gateway devices, and the residual buffer space of the plurality of slave gateway devices and the network delay between the plurality of slave gateway devices and the data source device are determined.
It should be understood that, the main gateway device also carries the data transmission task started by other devices, if the remaining buffer space of the main gateway device is insufficient, the data transmission efficiency will be low, so in this embodiment, the main gateway device monitors the remaining buffer space of the main gateway device and determines whether the main gateway device meets the transmission requirement. Specifically, whether the transmission requirement is met is determined by judging whether the residual buffer space of the gateway device is smaller than a preset threshold, wherein the preset threshold is a preset critical value for distinguishing the space size, and optionally, the preset threshold is the size of a transmission data packet supported by a protocol used by the gateway device.
After receiving the instruction of the master gateway, each slave gateway device monitors the remaining cache space, detects the network delay with the data source device, and feeds back the remaining cache space and the network delay with the data source device to the master gateway device.

It should be appreciated that the gateway identification is used to distinguish between different gateways and primary and secondary relationships, facilitating data transmission by the data source device based on the gateway identification. Specifically, the data source device performs average segmentation on the data to be transmitted according to the number n of the gateways, so that the data to be transmitted is divided into n data with equal size, and the n data with equal size are respectively sent to the master gateway device and the target slave gateway device according to the gateway identification. Optionally, the master gateway device and the plurality of slave gateway devices form a local area network, the data source device packages the n divided data according to the gateway identification, and then the n divided data are transmitted into the local area network in a broadcasting mode, and the master gateway device and the target slave gateway device read the data matched with the self identification so as to realize data transmission.

Further, when the data source equipment performs data segmentation, a data packet identifier is added to each segmented data according to the segmentation sequence, and after the data source equipment receives the data from the gateway equipment and the target slave gateway equipment, the data source equipment reads the data packet identifiers of the data, so that the data sequence is determined, and the target data is obtained by splicing according to the data sequence.
