Abstract
The invention discloses a data transmission method across operating systems, which is characterized in that a local area network which is used as a high-speed data channel and is used for communicating across the operating systems through a TCP/IP protocol is built in a product, communication modules of all the operating systems are connected to the same HUB or switch, and data transmission is carried out through TCP/IP protocol communication, and the method comprises the following steps: firstly, after a system is started, the communication modules of different operating systems mutually transmit the current IP addresses of the communication modules through a low-speed data channel; and step two, when transmitting data, according to the IP address obtained in the step one, the communication modules transmit data through a high-speed data channel. The invention firstly uses the low-speed data channel to acquire the IP address, and then carries out data transmission on the high-speed data channel according to the IP address, thereby improving the data transmission efficiency and controlling the cost.
Description
Technical Field
The invention relates to the technical field of multi-system electronic flat panel information transmission, in particular to a data transmission method crossing an operating system.
Background
At present, due to the design of the interactive electronic tablet, a plurality of operating systems such as Windows, android, iOS may exist at the same time, and when a user uses the interactive electronic tablet, the user needs to transmit data such as files and pictures across the operating systems so as to improve the user operation experience.
The traditional data transmission mode, such as adopting a low-speed data channel such as RS-232 and the like, cloud transmission or a special high-speed transmission chip for data transmission, has the related problems of low real-time transmission speed, high delay influenced by network speed, high cost of the special high-speed transmission chip and the like. If a high-speed communication mode of TCP/IP protocol is adopted, because the IP address of each communication module in each operation system is dynamically changed all the time, each communication module cannot acquire the IP address of the other party in time, and therefore cannot transmit data through a high-speed data channel.
Disclosure of Invention
The invention aims to provide a data transmission method across an operating system, which improves the real-time data transmission speed and realizes the control of the product cost.
In order to achieve the above object, the solution of the present invention is:
a data transmission method across operating systems is to build a local area network which is used as a high-speed data channel and is communicated with the operating systems through TCP/IP protocol in the product, the communication modules of the operating systems are connected to the same HUB or switch, and data transmission is carried out through TCP/IP protocol communication, and the method comprises the following steps:
firstly, after a system is started, the communication modules of different operating systems mutually transmit the current IP addresses of the communication modules through a low-speed data channel;
and step two, when transmitting data, according to the IP address obtained in the step one, the communication modules transmit data through a high-speed data channel.
In the first step, the low-speed data channel is an RS-232 serial port.
After the technical scheme is adopted, the invention firstly utilizes the low-speed data channel to carry out simple IP address information transmission, is not used for data transmission, and avoids the defect of low real-time transmission speed; the data transmission is carried out on the high-speed data channel according to the IP address acquired by the low-speed data channel, so that the problem that the data transmission cannot be carried out due to the fact that the IP address is dynamically changed all the time when the high-speed data channel is used is solved; meanwhile, the invention does not use a special data transmission chip, so that the cost of the product is controlled.
Drawings
FIG. 1 is a flow chart of an embodiment of the present invention.
Detailed Description
In order to further explain the technical scheme of the invention, the invention is explained in detail by specific examples.
The electronic tablet product is generally provided with a HUB/switch inside, and the communication modules of each operating system are connected to the same local area network, but the communication modules of each operating system are generally in an automatic IP acquisition mode, so that the IP addresses of the communication modules of each operating system are not fixed, and the program cannot directly transmit data through the IP addresses.
Referring to fig. 1, the present invention is a data transmission method across operating systems, in which a high-speed data channel network is built in a product, and a communication module of each operating system is connected to the high-speed data channel network to perform data transmission, including the following steps:
firstly, after a system is started, the communication modules of different operating systems mutually transmit the current IP addresses of the communication modules through a low-speed data channel;
and step two, when transmitting data, according to the IP address obtained in the step one, the communication modules transmit data through a high-speed data channel.
In some embodiments, the low-speed data channel in the first step is a serial port such as RS-232.
In some embodiments, the high-speed data channel in the second step is a local area network built inside the product, and the communication modules of the operating systems are connected to the same HUB or switch.
Through the scheme, the invention firstly utilizes the low-speed data channel to carry out simple IP address information transmission, is not used for data transmission, and avoids the defect of low real-time transmission speed; the data transmission is carried out on the high-speed data channel according to the IP address acquired by the low-speed data channel, so that the problem that the data transmission cannot be carried out due to the fact that the IP address is dynamically changed all the time when the high-speed data channel is used is solved; meanwhile, the invention does not use a special data transmission chip, so that the cost of the product is controlled.
The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
