[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] For details, please refer to Figure 1 , providing a PCIe adapter board, including:

[0030] A PCB board, wherein a first connector, a second connector, a multiplexer (PCIe MUX), a separator and an OPC connector are packaged on the PCB board;

[0031] The first port of the first connector is connected to the first input end of the multiplexer, and the first port of the second connector is connected to the second input end of the multiplexer; the output end of the multiplexer is connected to the first port of the OPC connector;

[0032] The second port of the OPC connector is connected to the input end of the splitter, the first output end of the splitter is connected to the second port of the first connector, and the second output end of the splitter is connected to the second port of the second connector.

[0033] The first connector and the second connector are both high-speed connectors. The high-speed connector of the mainboard is flexibly connected to the adapter board and the mainboard interface through a multiplexer and a separator. The external interface of the adapter board is a standard OCP interface. All external OCP cards can be connected to the high-speed connector on the mainboard through the OCP connector on the adapter board; the multiplexer can allow one interface to connect multiple devices, and the separator can decompose one signal into multiple signals, thereby realizing flexible switching of the interface.

[0034] Select the corresponding high-speed connector for the motherboard connector. The high-speed PCIe adapter board is designed to correspond to the motherboard high-speed connector 0 and the motherboard high-speed connector 1. In the four-controller high-density application scenario, by setting the multiplexer and separator settings, different high-speed connectors 0 and 1 are selected to realize the control of the OCP card by different interfaces of the controller.

[0035] The motherboard (controller) is connected to the adapter board through the PCIe interface. Different motherboards can realize different interface selections of the adapter board according to specific configurations. Figure 1 The middle channel selection interface can be selected by the motherboard CPDL. When the motherboard detects that the adapter board is in place, it selects high-speed connector 0 or high-speed connector 1 according to the configuration; the adapter board realizes the connection between the PCIe interface of different controllers and the OCP card; the link channel selection uses high-speed MUX and DEMUX to reduce the link Si problem, while improving the operation convenience of the board, avoiding the configuration circuit or deleting resistors / capacitors for channel configuration, etc.

[0036] The high-speed PCIe adapter board is designed with the corresponding OCP standard connector end, using the standard OCP connector interface, which can support all plug-in cards that meet the OCP standard and meet the signal transmission of the PCIe5.0 standard. The standard interface can be compatible with standard plug-in cards of other devices, saving development cycle and cost and enriching product types.

[0037] A PCIe interface is provided at the edge of the PCB board, and the first connector and the second connector are connected to the PCIe interface; the PCIe interface is used to connect to the PCIe slot of the mainboard. The mainboard includes multiple PCIe slots, and each PCIe slot is connected to a corresponding PCIe adapter board.

[0038] When the motherboard is connected to two PCIe adapter boards, a four-control environment is formed, such as Figure 2 In a four-controller environment, each controller PCIe interface can select the corresponding connector interface through the PCIe adapter board and the channel selector to achieve signal switching. The PCIe interface adopts the PCIe 5.0 X8 interface form; controllers ABCD are connected through the corresponding adapter board, and the specific channel selection is configured through the channel configuration interface. The dashed line part shows the controller connection method but does not limit the current connection method.

[0039] When the motherboard is connected to a PCIe adapter board, a dual-control environment is formed. Figure 3 shown.

[0040] A PCIe interface is provided at the edge of the PCB board, and the first connector and the second connector are connected to the PCIe interface; the PCIe interface is used to connect to the PCIe slot of the motherboard. The motherboard includes multiple PCIe slots, and each PCIe slot is connected to a corresponding PCIe adapter board. Figure 4 As shown, each of the SLOT1...SLOT14 slots contains one PCIe adapter board, each controller is connected to 14 slots, and there are 14 PCIe adapter boards in total. As an independent individual, the PCIe adapter board can be isolated from faults and can be replaced individually when a problem occurs, thereby reducing maintenance costs.

[0041] The first connector includes a selection circuit, and the output end of the selection circuit is connected to the control port of the multiplexer and the control port of the separator respectively. Figure 5 As shown, the selection circuit includes a MOS tube, the gate of the MOS tube is connected to the PCIe interface, the source of the MOS tube is connected to the control port of the multiplexer and the control port of the separator as the output end, the output end of the MOS tube is connected to the pull-up resistor; the drain of the MOS tube is grounded.

[0042] The selection circuit adds MOS isolation design in terms of reliability to prevent the back-end (IO adapter board) from affecting the front-end signal and realize the isolation function of signal failure; when the channel selection signal (input) is high, the output signal is low; when the channel selection signal (input) is low, the output signal is high. The multiplexer and separator conduct the corresponding lines based on the high and low levels.

[0043] The output end of the selection circuit is also connected to an LED lamp. The PCB board is installed in the chassis, and the lamp body of the LED lamp is installed on the surface of the chassis. The chassis includes a grid-shaped ventilation hole. The high and low level signals of the selection circuit are used as control signals of the LED lamp to make the LED lamp display the selected connector.

[0044] The OPC connector is connected to an external interface, and the external interface is used to connect to an external OPC standard card. The OPC connector is connected to multiple external interfaces, which can play the role of expanding the interface.

[0045] Although the present invention is described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, a person skilled in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions shall be within the scope of the present invention. Any person skilled in the art who is familiar with the present technical field may easily think of changes or substitutions within the technical scope disclosed in the present invention, and these shall be within the scope of protection of the present invention.
