For better understanding of the embodiments of the present invention, the following describes the working process of the display screen control system provided in this embodiment in detail with reference to fig. 3a to 3 c. The display screen control system comprises two system controllers, for example, the two system controllers have the same structure, and each system controller has two working modes: the image data processing mode and the photoelectric conversion mode can be switched as required.

Referring to fig. 3a, a system controller receiving an input video source corresponds to the system controller 11 of fig. 2, which employs an image data processing mode, and a system controller connected to a module controller corresponds to the system controller 12 of fig. 2, which employs a photoelectric conversion mode. The input video source is for example output by a PC or a video processor. For convenience of description, the programmable logic device of the system controller in the image data processing mode is internally divided into a video decoding module, a data storage control logic, an output image control logic and an optical port output control logic, and the programmable logic device of the system controller in the photoelectric conversion mode is internally divided into an optical port data analysis logic and a network port output control logic.

Specifically, the video decoding module decodes an input video source, the decoded video source is directly and temporarily stored in SDRAM or DDR through a data storage control logic, then a target video source is taken out of the SDRAM or DDR through an output image control logic according to the area position carried by each network cable interface, namely a network port, and the target video source is transmitted to a next connected system controller through an optical port output control logic so as to finish the storage and sending functions of the input video source. And the optical port data analysis logic of the next system controller analyzes the received target video source to obtain the content of the video source to be output by the corresponding network port, and then the analyzed video source is output to the module controller through the network port output control logic, so that the function of inputting the video source from the optical fiber interface to the network cable interface and outputting the video source is completed. And the module controller outputs the analyzed video source to the LED display screen to realize the output display of the whole video source.

Further, when the system controller is in the image data processing mode, the output image control logic may also take out the target video source from the SDRAM or DDR and transmit the target video source to the next system controller connected thereto through the network port output control logic, the network port data parsing logic corresponding to the next system controller parses the received target video source to obtain the content of the video source to be output by the corresponding network port, and then the parsed video source is output to the next system controller through the optical port output control logic.

Specifically, the image data processing mode of the system controller will be briefly described with reference to fig. 3 b. As shown in FIG. 3b, the description will be made by taking the net ports 1-8 and the light ports 1-2 as examples, but the present invention is not limited thereto. The video decoding module of the system controller decodes an input video source, the decoded video source is directly and temporarily stored in a memorizer such as SDRAM or DDR through a data storage control logic, an output image control logic takes out output image data required by a network port, namely a target video source from the SDRAM or DDR according to the load positions and the load sizes of the network ports 1-8, image data is sent according to a packet format which can be identified by the module controller, the image data sent by the network ports 1-8 are coded through an optical port output control logic, the coded image data are respectively sent to an optical port 1 and an optical port 2 to be output, wherein the image data in the optical port 2 are copies of the image data in the optical port 1, namely the output contents are the same. In addition, the output image control logic can also take out the output image data required by the network port from the SDRAM or DDR according to the loading position and the loading size of the network port 1-8, send the image data according to the packet format recognized by the module controller, respectively send the image data to the network port 1-8 through the network port output control logic, and output the image data through the network port.

Specifically, the photoelectric conversion mode of the system controller will be briefly described with reference to fig. 3 c. Similarly, taking the network ports 1-8 and the optical ports 1-2 as examples, the system controller can realize the function of outputting image data from the optical port to the network port in a photoelectric conversion mode, and complete the transmission and analysis of the image data. And after the optical port of the system controller receives the image data, the optical port data analysis logic performs data analysis on the image data transmitted by the physical interfaces of the optical port 1 and the optical port 2, and respectively analyzes the image data corresponding to the network ports 1-8. When detecting that the optical port 1 and the optical port 2 are connected simultaneously or only the optical port 1 is connected, the network port output control logic outputs the image data transmitted by the optical port 1 to the physical interfaces of the network ports 1-8 according to the corresponding relation respectively, and transmits the image data to the module controller through the network cable. When only the optical port 2 is detected to be connected, the network port output control logic outputs the image data transmitted by the optical port 2 to the physical interfaces of the network ports 1-8 according to the corresponding relation respectively, and transmits the image data to the module controller through the network cable. In this photoelectric conversion mode, the priority of port 1 is higher than that of port 2, and port 2 is mainly used for backup. In addition, the system controller can also realize the function of outputting image data from the network port to the optical port in the photoelectric conversion mode. Specifically, after the network interface of the system controller receives the image data, the network interface data analysis logic analyzes the image data transmitted by the physical interfaces of the network interfaces 1-8, and transmits the image data to the optical interface output control logic, so that the image data is encoded and then respectively transmitted to the physical interfaces of the

optical interfaces

1 and 2 for output, wherein the priority of the optical interface 1 is higher than that of the optical interface 2, and the optical interface 2 is mainly used for backup.

It should be noted that the embodiments of the present invention do not limit the specific number of the system controllers and the module controllers. Because the optical fiber interface and the network cable interface can carry out bidirectional data transmission, the number of the system controllers can be increased according to the requirement in order to realize the long-distance optical fiber transmission. In the practical application process, the system controller and the module controller can be increased or decreased according to the specific application scene, and the corresponding working mode of the system controller can be switched.
