Abstract

The invention provides a data transmission method and device. The method comprises the following steps: acquiring an information data packet; dividing the preset multicast address into an identification code, a serial number code and a data code; selecting the data bit length of the data code according to a preset demand, and determining the data bit length of the identification code and the serial number code; splitting the information data packet according to the data bit length of each coding field; encoding the split information data packets, and storing the encoded information data packets into corresponding data bits to obtain a plurality of multicast data frames so as to realize automatic network distribution; and respectively sending each multicast data frame to a network equipment end. The method comprises the following steps: splitting an obtained information data packet through a user side to obtain a plurality of multicast data frames so as to realize automatic network distribution, and then sending each multicast data frame to a network equipment side; and by using the multicast data frame as an information carrier, providing an efficient channel for data transmission, and therefore, the transmission efficiency is improved while the security of wireless network data transmission is ensured.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data transmission method and device. Background technique [0002] The automatic network configuration function needs to be used in the printer to realize data transmission. The existing method generally transmits the Service Set Identifier (Service Set Identifier, SSID) and password of the wireless AP through the UDP broadcast packet, and the network device then passes the received Analyze the UDP broadcast packet, obtain the SSID and password of the wireless AP after analysis, and then automatically connect to the wireless AP. The existing data transmission method can only use the length value of the UDP data packet to transmit the information in order to ensure the use of the UDP broadcast packet to transmit the SSID and password of the wireless AP without purpose, but the transmission efficiency of the data cannot be guaranteed. Contents of the invention [00...
