In addition, the module controller 300 is electrically connected to one second gate 110 of the photoelectric conversion apparatus 100 through its own gate (not shown in fig. 5).
Similarly, the microcontroller 206 may be, for example, an MCU (Micro controller Unit) or an arm (advanced RISC machine) processor, and the Programmable logic device 204 may be, for example, an FPGA (Field Programmable Gate Array), which is not limited herein.
In this embodiment, a control instruction may be sent to the photoelectric conversion apparatus 100 by upper computer software on an upper computer (such as a PC in fig. 5) for causing the photoelectric conversion apparatus 100 to control the display controller 100 according to the control instruction. As shown in fig. 5, in the embodiment of the present invention, a PC may be connected to the first port 106 of the photoelectric conversion apparatus 100, and may also be connected to one of the plurality of second ports 110 of the photoelectric conversion apparatus 100.
In the case where a PC is connected to the first portal 106, the control method of the present embodiment is as follows:
the microcontroller 1040 receives a control instruction containing an instruction identifier sent by the PC (specifically, upper computer software thereon) via the first network interface 106, and determines a target control device corresponding to the control instruction according to the instruction identifier contained in the control instruction.
In the case where the microcontroller 1040 determines that the target control device is the display Controller 200, the microcontroller 1040 transmits the control instruction to the programmable logic device 1042 as it is via, for example, an FSMC (Flexible Static Memory Controller) Interface/SPI (Serial Peripheral Interface). After receiving the control instruction, the programmable logic device 1042 determines that the target receiving device is the display controller 200 according to the instruction identifier included in the control instruction, and then sends the control instruction to the display controller 200 via the optical port 102 as it is to control the display controller 200. The processing procedure of the display controller 200 is as follows: the programmable logic device 204 of the display controller 200 receives the control instructions via the optical port 202 and sends the control instructions to the microcontroller 206. The microcontroller 206 parses the control instructions to obtain the instruction content. The microcontroller 206 sends the instruction content to the programmable logic device 204. When the instruction content indicates to acquire status information of the display controller 200, for example, connection status information of an optical port and a network port (not shown in fig. 5) of the display controller 200, the programmable logic device 204 acquires the status information according to the instruction content, and sends the status information to the microcontroller 206, so that the microcontroller 206 performs a packing process on the status information to generate feedback information and sends the feedback information to the photoelectric conversion apparatus 100 via the programmable logic device 204 and the optical port 202 in sequence. The photoelectric conversion apparatus 100 sequentially passes through the optical port 102, the processing module 104 (specifically, the programmable logic device 1042 and the microcontroller 1040), and the first network port 106 to send feedback information to the PC to display the status information on the upper computer software on the PC, so as to present the status information to the user. When the instruction contents instruct the display controller 200 to switch the video source, the programmable logic device 204 performs switching of the video source, performs operations related to image processing, and transmits video image data to the photoelectric conversion apparatus 100 through the optical port 202 and to the module controller 300 electrically connected to the photoelectric conversion apparatus 100 via the photoelectric conversion apparatus 100 for video image presentation.
In the case where the microcontroller 1040 determines that the target control device is the photoelectric conversion device 100, the microcontroller 1040 analyzes the control instruction to obtain instruction content, and sends the instruction content to the programmable logic device 1042. The programmable logic device 1042 acquires state information of the photoelectric conversion apparatus 100 (for example, a port and an optical port connection state of the photoelectric conversion apparatus 100) according to the instruction content, sends the state information to the microcontroller 1040, so that the microcontroller 1040 performs a packaging process on the state information to generate feedback information, and sends the feedback information to the PC via the first port 106 to display the state information on upper computer software on the PC, so as to present the state information to a user.
It should be noted that the instruction identifier may be, for example, a digital identifier such as 0 or 1, and the target control device for identifying the control instruction is the photoelectric conversion device 100 or the display controller 200, but of course, the instruction identifier may also be identified in other manners, and this embodiment is not particularly limited herein as long as the instruction identifier can be used for identifying the target control device.
In the case where a PC is connected to the second portal 110, the control method of the present embodiment is as follows:
the programmable logic device 1042 receives a control instruction containing an instruction identifier sent by a PC (specifically, upper computer software thereon) via the second network interface 110 and the multi-output ethernet physical layer transceiver 108, and determines a target control device corresponding to the control instruction according to the instruction identifier contained in the control instruction.
In the case where the programmable logic device 1042 determines that the target control apparatus is the display controller 200, the programmable logic device 1042 sends a control instruction to the display controller 200 via the optical port 102 as it is to control the display controller 200. The processing procedure of the display controller 200 is as follows: the programmable logic device 204 receives the control instructions via the optical port 202 and sends the control instructions to the microcontroller 206. The microcontroller 206 parses the control instructions to obtain the instruction content. The microcontroller 206 sends the instruction content to the programmable logic device 204. When the instruction content indicates to acquire status information of the display controller 200, for example, connection status information of an optical port and a network port (not shown in fig. 5) of the display controller 200, the programmable logic device 204 acquires the status information according to the instruction content, and sends the status information to the microcontroller 206, so that the microcontroller 206 performs a packing process on the status information to generate feedback information and sends the feedback information to the photoelectric conversion apparatus 100 via the programmable logic device 204 and the optical port 202 in sequence. The photoelectric conversion device 100 sequentially sends the feedback information to the PC through the optical port 102, the programmable logic device 1042, the multi-output ethernet physical layer transceiver 108, and the second port 110 to display the status information on the upper computer software on the PC, so as to present the status information to the user. When the instruction contents instruct the display controller 200 to switch the video source, the programmable logic device 204 performs switching of the video source, performs operations related to image processing, and transmits video image data to the photoelectric conversion apparatus 100 through the optical port 202 and to the module controller 300 electrically connected to the photoelectric conversion apparatus 100 via the photoelectric conversion apparatus 100 for video image presentation.
In the case where the programmable logic device 1042 determines that the target control apparatus is the photoelectric conversion apparatus 100, the programmable logic device 1042 sends the control instruction to the microcontroller 1040 as it is. The microcontroller 1040 parses the control command to obtain command content, and sends the command content to the programmable logic device 1042. The programmable logic device 1042 acquires state information (for example, a connection state of an internet port and an optical port of the photoelectric conversion device) of the photoelectric conversion device 100 according to the instruction content and sends the state information to the microcontroller 1040, so that the microcontroller 1040 performs a packaging process on the state information to generate feedback information, and sends the feedback information to the PC via the programmable logic device 1042, the multi-output ethernet physical layer transceiver 108, and the second internet access 110 in sequence to display the state information on upper computer software on the PC, so as to present the state information to a user.
In light of the above, it should be noted that in this embodiment, the physical transmission bandwidth of the optical interface 202 and the optical interface 102 may be, for example, 10Gbps/40Gbps, and the physical transmission bandwidth of each network interface may be, for example, 1Gbps/5 Gbps. The number of outputs of the multi-output ethernet physical layer transceiver 108 may be, for example, 8, and correspondingly, the number of the second network ports 110 is 8, in which case the programmable logic device 1042 may implement eight shares of the physical transmission bandwidth of the optical port 102. When the PC is connected to the first port 106 to control the display controller 200, the present embodiment can perform output of image data by controlling seven ports among the eight second ports 110, while the remaining one of the second ports 110 is not used to perform output of image data. When a PC is connected to one second portal 110 to control the display controller 200, then the remaining seven second portals 110 are available for outputting image data, while the first portal 106 is available for connecting to a PC and only for controlling the photoelectric conversion apparatus 100. It should be noted that in the present embodiment, one of the plurality of second network ports 110 may be selected as a fixed interface for the PC to access the display controller 200, so that the upper computer software of the PC only needs to directly connect the network to the second network port 110, and then the upper computer software of the PC may send a control command for controlling the display controller 200 to the display controller 200 via the photoelectric conversion apparatus 100 to control the display controller 200.

The LED display system 600 includes the display control system 400 and the LED display screen 500. The at least one module controller 300 in the display control system 400 may be connected with the LED display screen 500, for example, by a flat cable. Specifically, the LED display screen 500 may, for example, include a display module that is carried by at least one module controller 300 included in the display control system 400. For example, the display module is an LED module, and the LED module includes one or more LED lamp panels including LED display pixels.
In summary, the embodiment of the present invention implements control over the display controller by the photoelectric conversion device, so that a user does not need to back and forth between the display controller and the photoelectric conversion device to implement control over the display controller in a process of using the display control system including the display controller and the photoelectric conversion device, thereby bringing convenience to the user operation.
