Cross-operating-system data transmission method

Abstract

The invention discloses a cross-operating-system data transmission method, which is characterized in that a cross-operating-system local area network which carries out communication through a TCP / IP (Transmission Control Protocol / Internet Protocol) is built in a product as a high-speed data channel, communication modules of all operating systems are connected to the same HUB or switch, and data transmission is carried out through TCP / IP communication, and comprises the following steps: step 1, after the systems are started, the communication modules of all the operating systems are connected to the same HUB or switch; the current IP address of each communication module is transmitted between the communication modules of different operating systems through a low-speed data channel; and step 2, during data transmission, according to the IP address obtained in the step 1, data transmission is carried out among the communication modules through a high-speed data channel. According to the invention, the IP address is obtained by using the low-speed data channel, and then data transmission is carried out in the high-speed data channel according to the IP address, so that the data transmission efficiency is improved, and the cost is controlled.

Description

technical field [0001] The invention relates to the technical field of multi-system electronic tablet information transmission, in particular to a data transmission method across operating systems. Background technique [0002] Due to its own design, the current interactive electronic tablet may have multiple operating systems such as Windows, Android, and iOS. When users use it, they need to transfer data such as files and pictures across operating systems to improve user experience. [0003] Traditional data transmission methods, such as using low-speed data channels such as RS-232, cloud transmission or dedicated high-speed transmission chips for data transmission, have problems such as slow real-time transmission speed, high delay affected by network speed, and high cost of dedicated high-speed transmission chips. . If the high-speed communication mode of the TCP / IP protocol is adopted, since the IP addresses of each communication module in each operating system are con...

Problems solved by technology

[0003] Traditional data transmission methods, such as using low-speed data channels such as RS-232, cloud transmission or dedicated high-speed transmission chips for data transmission, have problems such as slow real-time transmission speed, high delay affected by network speed, and high cost of dedicated high-speed transmission chips.

If the high-speed communication mode of the TCP / IP protocol is adopted, since the IP addresses of each communication module in each operating system are constantly changing dynamically, each communication module cannot perform data transmission through a high-speed data channel because it cannot know the IP address of the other party in time
