The brand relevancy is generalComparing and matching the brands of the terminal and the display terminal, wherein the brand correlation is 1 when the two brands are the same (for example, the terminal and the display terminal are both produced by company A), and when the two brands are different, further judging whether the brands are related brands (namely, whether the brands belong to two companies of the same parent company, for example, the company A flags two subsidiary companies a1 and a company a2 which respectively produce the terminal and the display terminal), wherein the brand correlation can be any value from 0.5 to 0.9, and can be any value from 0 to 0.4 if the brands are not related; the system relevancy is obtained by comparing the terminal with the built-in system of the display end, the determination mode of the system relevancy is similar to the brand relevancy, please refer to the determination mode of the brand relevancy for determination, which is not repeated, for example, it is preferentially determined whether the systems are the same (for example, both are an android system or a hongmeng system), if not, the system relevancy is determined to be 0-0.4, and is not specifically limited, if yes, it is determined whether the systems are the same, if the systems are the same, the system relevancy is 1, otherwise, the system relevancy is determined to be 0.5-0.9; the processing frequency is the operating frequency of a processor in the equipment, and is not limited; the memory is an internal memory and a main memory in the device, and is used for temporarily storing operation data in the processor and data exchanged with an external memory such as a hard disk, and the memory parameter is the size of a storage space of the memory. Further, the relationship between the reference coefficients a, b, c, d is preferably a + b + c + d =1, which may be determined according to the importance of the brand correlation, the system correlation, the processing brand, and the storage parameter in the matching degree value, and may be, for example, a =0.2, b =0.3, c =0.3, and d = 0.2.
Further, based on the foregoing embodiment, in this embodiment, the screen projection data of one terminal may be simultaneously displayed on multiple display terminals, and at this time, the processing module needs to send the screen projection content of one terminal to the multiple display terminals for displaying.
Further, in view of the fact that data feedback may be involved in the use of the relay device, and the device system may already perform log generation and other operations on the data, as a preferable scheme, in this embodiment, the processing module further includes a feedback unit for generating and storing a processing log, and sending the processing log to the terminal through the receiving module. At this time, the receiving module exchanges data with the connected terminal, that is, not only the data of the terminal is received, but also the corresponding data is fed back to the terminal.
Further, in consideration of the fact that in practical application, in order to determine a data transmission channel between a terminal and a display end, as a preferred scheme, in this embodiment, the terminal parameter further includes a terminal ID; the display parameters further include a display ID; the processing module specifically includes, when determining the corresponding screen projection channel: and forming a display end list by all display IDs, feeding back the display end list to all terminals through the receiving module, receiving selection data of each terminal through the receiving module, correspondingly setting the display IDs and the terminal IDs according to the selection data, and constructing the screen projection channel. The processing module is further configured to obtain display IDs of all display terminals through the wireless docking module, obtain terminal IDs of all terminals through the receiving module, form a display terminal list with all display IDs, feed back the display terminal list to all terminals through the receiving module, receive selection data of each terminal through the receiving module, and set the display IDs and the terminal IDs correspondingly according to the selection data. In one embodiment, the correspondence setting may be a one-to-one (i.e., one terminal sets one display terminal) setting, and in another embodiment, the correspondence setting may also be a one-to-many (i.e., one terminal sets multiple display terminals) setting. Specifically, the terminal ID and the display ID may be a unique identification code, a K code, a name, and the like of the corresponding device, which is not limited in the present invention.

and when the number of the terminals is larger than that of the display ends, determining the corresponding screen projection relation according to the corresponding set sequence, and determining the corresponding screen projection channel according to the screen projection relation. It should be noted that the correspondence is set as a process of associating between the terminal ID and the display ID; the screen projection relation is an association relation between the terminal ID and the display ID, only the terminal which determines the corresponding screen projection relation can send screen projection data to the display end according to the screen projection channel, and the screen projection operation cannot be realized by the terminal which fails to realize corresponding setting (namely the corresponding screen projection relation is not determined), namely the terminal which is associated firstly can realize the corresponding setting step, and the terminal which operates slowly cannot realize the corresponding setting step. That is, when the number of terminals is greater than the number of display terminals, the terminals selected first can be matched with the display terminals, and the terminals after the terminal selection cannot be set correspondingly. Of course, further, after a terminal selects a corresponding display end, the processing module feeds back data to other terminals through the receiving module, so that the display ID of the selected display end is deleted in the display end list or displayed in a non-selectable state.

Specifically, when the number of the terminals is less than or equal to the number of the display terminals, that is, under the condition one/two relationship, because the condition that the display terminals cannot be matched with the terminals does not occur, special setting is not required, and the terminals are matched normally. And under the third condition, determining the corresponding screen projection relation according to the sequence of the corresponding setting, wherein the terminal which cannot realize the corresponding setting cannot realize the screen projection operation.
Further, in consideration of the connection between the relay device and the plurality of terminals, as a preferred scheme, in this embodiment, the receiving module has an input interface, and the input interface includes one or a combination of a USB interface, an HDMI interface, and a Type-C interface. Of course, the number of each Type of interface is not limited, that is, when the input interface is one Type (for example, a Type-C interface), the input interface may also be a plurality of the same interfaces, the specific number may be set according to actual requirements, and meanwhile, the number and the Type of the interfaces are expanded by using the docking station, which is not limited in the present invention.

The processing module is also used for comparing the number between the terminal and the display end; when the number of the terminals is larger than that of the display ends, the corresponding screen projection relation is determined according to the sequence of the corresponding setting, and the screen projection operation cannot be realized by the terminal which cannot realize the corresponding setting. That is, when the number of terminals is greater than the number of display terminals, the terminals selected first can be matched with the display terminals, and the terminals after the terminal selection cannot be set correspondingly. Of course, further, after a terminal selects a corresponding display end, the processing module feeds back data to other terminals through the receiving module, so that the display ID of the selected display end is deleted in the display end list or displayed in a non-selectable state.
Furthermore, when the number of the terminals is less than or equal to the number of the display ends, no special setting is needed because the situation that the terminals cannot be matched with the display ends does not occur.
Referring to fig. 3, the present invention further provides a wireless screen projection system, which includes one or more terminals, one or more display terminals, and the wireless screen projection relay device. The wireless screen projection system uses the transfer device to ensure the normal operation of the wireless screen projection system based on the control method in the embodiment, so that a plurality of terminals can respectively project screen projection data to a plurality of display ends, one-to-one or one-to-many display modes are comprehensively realized, and the normal operation of the wireless screen projection system is ensured.
