Problems solved by technology

For example, in the application of printer communication, because the control information and image data share the USB communication channel, when there are many printing data, a large amount of printing image data will block the communication interface, resulting in the situation that the control information cannot be transmitted or the transmission is not timely.
[0003] The current solution is to use a USB hub to convert multiple USB interfaces to send control information and image data respectively. However, for the printing system, the timing requirements for data are relatively high, and multiple USB interfaces will cause timing errors in data transmission, resulting in The transmission accuracy is reduced. Therefore, the existing solutions cannot meet the needs of batch data transmission timeliness and transmission accuracy

Embodiment Construction

[0021] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0022] Such as figure 1 As shown, it is a schematic flowchart provided by an embodiment of the channel sharing method of the present invention. The channel sharing method is used for data and control information, and the data and control information share the target channel for transmission. The channel sharing method includes:

[0023] S1, the host computer respectively packs data and control information according to a preset frame structure, and generates corresponding frame information for transmission in a target channel, wherein the preset frame structure includes identification information for distinguishing data and control information;

[0024] S2, the lower computer monitors the target channel, analyzes...

Abstract

The invention discloses a channel sharing method and system for data and control information, and relates to the field of data communication. The method comprises the steps that an upper computer packages data and control information according to a preset frame structure, generates corresponding frame information and transmits the frame information in a target channel; the lower computer monitors the target channel, analyzes and verifies the received frame information, judges the information type of the frame information according to the identification information after the verification is passed, and determines a processing mode for processing the data or the control information according to the information type; and the application layer equipment processes the data or the control information according to the selected processing mode. The method is suitable for a printing system and other scenes with large data transmission quantity and high time sequence requirements, data and control information can be transmitted on a shared channel, data transmission can be guaranteed, timely transmission of the control information can be guaranteed, and the effect of effectively reducing channel blocking can be achieved under the condition that the data quantity is large.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a channel sharing method and system for data and control information. Background technique [0002] At present, when using the USB communication scheme of similar chips such as FT232, there is a problem that information can only be sent sequentially and has no priority. For example, in printer communication applications, since the control information and image data share the USB communication channel, when there is a large amount of printing data, a large amount of printing image data will block the communication interface, resulting in the situation that the control information cannot be transmitted or the transmission is not timely. [0003] The current solution is to use a USB hub to convert multiple USB interfaces to send control information and image data respectively. However, for the printing system, the timing requirements for data are relatively high, and multiple USB i...
