Abstract
The invention discloses a data transmission method of a cross-operating system, which is characterized in that a local area network which is cross-operating system and communicates through a TCP/IP protocol is built in a product to be used as a high-speed data channel, communication modules of all operating systems are connected to the same HUB or a switchboard and communicate through the TCP/IP protocol to carry out data transmission, and the method comprises the following steps: after a system is started, communication modules of different operating systems transmit current IP addresses of the communication modules to each other through a low-speed data channel; and step two, when transmitting data, according to the IP address obtained in the step one, data transmission is carried out among the communication modules through a high-speed data channel. The invention firstly utilizes the low-speed data channel to obtain the IP address, and then carries out data transmission in the high-speed data channel according to the IP address, thereby not only improving the data transmission efficiency, but also controlling the cost.
Description
Technical Field
The invention relates to the technical field of multi-system electronic flat information transmission, in particular to a data transmission method of a cross-operating system.
Background
At present, due to the self-design of an interactive electronic tablet, multiple operating systems such as Windows, Android, iOS and the like may exist at the same time, and when a user uses the interactive electronic tablet, data such as files, pictures and the like need to be transmitted across the operating systems so as to improve the operation experience of the user.
In a traditional data transmission mode, if a low-speed data channel such as RS-232 and the like and a cloud transmission or special high-speed transmission chip are adopted for data transmission, the problems of low real-time transmission speed, high delay caused by the influence of network speed, high cost of the special high-speed transmission chip and the like exist respectively. If a high-speed communication mode of a TCP/IP protocol is adopted, because the IP addresses of the communication modules in each operating system are dynamically changed all the time, each communication module cannot acquire the IP address of the other side in time and cannot transmit data through a high-speed data channel.
Disclosure of Invention
The invention aims to provide a data transmission method of a cross-operating system, which improves the real-time data transmission speed and realizes the control of product cost.
In order to achieve the above purpose, the solution of the invention is:
a data transmission method across operating systems is characterized in that a local area network which is across operating systems and communicates through a TCP/IP protocol is built in a product to serve as a high-speed data channel, communication modules of all the operating systems are connected to the same HUB or a switch and communicate through the TCP/IP protocol to perform data transmission, and the method comprises the following steps:
after a system is started, communication modules of different operating systems transmit current IP addresses of the communication modules to each other through a low-speed data channel;
and step two, when transmitting data, according to the IP address obtained in the step one, data transmission is carried out among the communication modules 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, and is not used for data transmission, thereby avoiding the defect of low real-time transmission speed; data transmission is carried out in 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 because 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 schematic flow chart of an embodiment of the present invention.
Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.
The electronic tablet product is generally provided with a HUB/switch inside to connect the communication modules of each operating system to the same local area network, but generally adopts an automatic IP acquisition mode, so that the IP addresses of the communication modules of each operating system are not fixed, and a program cannot directly transmit data through the IP addresses.
Referring to fig. 1, the present invention is a data transmission method across operating systems, a high-speed data channel network is built in a product, and communication modules of each operating system are connected to the high-speed data channel network for data transmission, including the following steps:
after a system is started, communication modules of different operating systems transmit current IP addresses of the communication modules to each other through a low-speed data channel;
and step two, when transmitting data, according to the IP address obtained in the step one, data transmission is carried out among the communication modules 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, and is not used for data transmission, thereby avoiding the defect of low real-time transmission speed; data transmission is carried out in 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 because 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 embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
