[0036] Reference Figure 1 , Figure 1 This is a schematic diagram of the architecture of the Feiteng D3000 main control card based on the 6U VPX architecture provided in an embodiment of the present application, which includes the main control card including a main control board, and the main control board includes a processor, an IO expansion bridge chip, an MCU, a network adapter, and an Ethernet adapter;

[0037] Specifically, the main control board of this application adopts a 6U VPX board card, which complies with the 6U VPX specification and is compatible with the existing VPX system, making it convenient for users to integrate and deploy.

[0038] The processor is a Feiteng D3000 processor, with multiple DDR5 memories and SSD storage media on board.

[0039] Specifically, if Figure 1 As shown, the Feiteng D3000 processor (pictured), integrates eight high-performance FTC862 processor cores, onboard DDR5 (Double Data Rate 5) memory chips and SSD (Solid State Drive) storage chips, providing high-speed data storage and buffering capabilities.

In addition, the DDR5 memory chips include ECC (Error Checking and Correcting) memory, a memory module with special error correction capabilities that can detect and correct data errors in memory.

[0040] The processor is connected to the first end of the IO expansion bridge chip through a first PCIE interface.

[0041] Specifically, the first PCIE interface uses a PCIE4.0 x8 (Peripheral Component Interconnect Express 4.0 x8, the 4th generation Peripheral Component Interconnect Express x8) interface, where x8 indicates that the slot supports 8 channels.

[0042] More specifically, the IO expansion bridge chip uses the Feiteng X100 bridge chip, which is responsible for connecting and managing data transmission between various peripherals and the motherboard. Based on the high-speed transmission capability of PCIE and the multi-functional interface of the IO expansion bridge chip, it can achieve high-speed communication and expand external interfaces.

[0043] The processor is connected to the first end of the MCU via an I2C bus.

[0044] Specifically, the I2C (Inter-Integrated Circuit) bus is a two-wire serial bus used to connect microcontrollers and their peripherals. By interconnecting the MCU and processor via the I2C bus, power management can be implemented on the MCU chip based on the MCU's needs for temperature and voltage monitoring, ensuring stable operation of the main control card.

[0045] Combine Figure 1 The working principle of the main control board provided in this application is described as follows: the PCIE4.0 X4 signal output by D3000 is connected to WX1860AL4, and then WX1860AL4 outputs four sets of Gigabit network signals to the P4 connector of VPX, thereby realizing Gigabit network interconnection;

[0046] The PCIE5.0 X8 signal output by D3000 is connected to RNP N10G-X8, and then RNP N10G-X8 outputs eight groups of 10G network signals to the P2 connector of VPX, thus realizing 10G network interconnection.

[0047] The SGMII signal output by D3000 is connected to YT8521, and then YT8521 outputs a set of Gigabit network signals to the P2 connector of VPX, thus realizing Gigabit network interconnection. This set of Gigabit network signals is reserved for connection to the onboard RJ45 interface and is reserved for pre-debugging use.

[0048] The PCIE4.0 X8 signal output by D3000 is connected to X100, and then X100 outputs six sets of USB3.0 signals, four of which are output to the P3 connector of VPX and two to the front USB connector on the board, thus realizing data transmission and device connection.

[0049] The D3000 outputs a set of SATA3.0 signals that are connected to the onboard mSATA port for connecting an external mSATA hard drive to increase the system's storage space. The X100 outputs three sets of SATA3.0 signals, two of which are output to the VPX's P3 connector, and one of which is connected to the onboard SSD chip for system environment setup and installation.

[0050] The X100 outputs two sets of DP1.4 signals. One set is connected to the LT8711V chip, which outputs VGA signals to the onboard front VGA connector for VGA display. The other set is connected to the GSV2201D chip, which outputs HDMI signals to the P3 connector of the VPX for HDMI display.

[0051] The RMII signal output by the MCU is connected to the YT8512 chip, which outputs a 100M signal to the onboard RJ45 connector for remote power on and off functions.

[0052] More specifically, refer to Figure 2 , Figure 2 This is a schematic diagram of the MCU module provided in an embodiment of the present application, including a hot plug detection module, a serial port switching module, an indicator light module, a power status detection module, a remote power on / off module, an optical module communication module, a hardware status reporting module, a current monitoring module, a voltage detection module, a fan speed control module and a fan speed detection module.

[0055] The indicator light module includes an MCU status indicator, an N10 10 Gigabit controller LED indicator, and a power status indicator. The MCU status indicator is connected to the MCU via one GPIO port, the N10 10 Gigabit controller LED indicator is connected to the MCU via eight GPIO ports, and the power status indicator is connected to the MCU via two GPIO ports.

[0056] The power status detection module is connected to the MCU through 28 GPIO ports. It is used to monitor the power status and control the power-on sequence. The power-on sequence control is used to ensure that each power pin and functional module is powered and initialized in a specific order and time interval during the MCU power-on process.

[0057] The remote power on / off module is connected via PHY (Physical Layer Device);

[0058] The optical module communication module is connected to the MCU via an I2C bus for N10 10G optical module communication;

[0059] The hardware status reporting module is connected to the MCU via an I2C bus and is used to report the hardware status information of the main control board and daughter card information to the processor through the MCU. The daughter card information is collected by the daughter card information collection module, which is connected to the MCU via two IPMB (Intelligent Platform Management Bus) channels.

[0060] The current monitoring module is connected to the MCU via an I2C bus to monitor the current of the I2C bus;

[0061] The voltage monitoring module is connected to the MCU through fourteen ADC channels, which is used to monitor multiple voltage points simultaneously through the MCU to improve the efficiency and flexibility of voltage monitoring;

[0062] The fan speed control module uses two PWM signals from the MCU to control the fan speed. The fan speed detection module is connected to the MCU through two pulse counters (CNTs). The MCU counts the fan's pulse signals to determine the fan speed.

[0063] The processor is connected to the network adapter via a second PCIE interface.

[0064] Specifically, the second PCIE port uses PCIE 5.0 x8 (Peripheral Component Interconnect Express 5.0 x8), where x8 indicates the slot supports eight lanes. The network adapter used is RNP N10G-x8. This solution ensures a high-speed and stable network connection.

[0065] The processor is connected to the Ethernet adapter via a third PCIE interface.

[0066] Specifically, the third PCIE interface uses a PCIE4.0 x4 (Peripheral Component Interconnect Express 4.0 x4) interface, where x4 indicates that the slot supports 4 channels; the Ethernet adapter model used is WX1860AL4.

[0067] More specifically, by adopting the above technical solution, the processor integrates an Ethernet controller that supports one Gigabit Ethernet and one 10 Gigabit Ethernet, meaning it can handle two different types of network connections simultaneously. For example, one port can use Gigabit Ethernet and another port can use 10 Gigabit Ethernet, improving flexibility and scalability.

[0068] Furthermore, the present application also provides a test carrier board, which is used to test the various functions of the main control board provided by the present application. The following is a detailed description:

[0069] The main control board includes seven VPX connectors, and the test carrier includes seven VPX connectors. All the VPX connectors of the main control board are connected one by one with all the VPX connectors of the test carrier, so as to test various signal functions of the main control board through the test carrier.

[0070] Specifically, refer to Figure 3 , Figure 3 This is a connection diagram of the main control board and the test carrier board provided in an embodiment of the present application. It can be seen that the main control board includes seven VPX connectors from P0 to P6, and the test carrier board includes seven VPX connectors from J0 to J6, and their connection relationships correspond one to one.

[0071] Specifically, VPX connectors are typically pluggable, making them easy to install and remove. To further ensure connection reliability, VPX connectors often employ a mechanical locking mechanism, which provides an additional locking device after connection to prevent accidental disconnection. Furthermore, VPX connectors feature multiple conductive contact points to provide a stable electrical connection, which helps improve signal integrity and current carrying capacity.

[0072] Furthermore, some VPX connectors support hot-swappable functionality, allowing modules to be replaced without powering off the system, improving system availability. They can also provide a variety of arrangements and configurations based on different application requirements, flexibly adapting to different interface requirements, for example, supporting different numbers of data channels and power supply modes.

[0073] More specifically, the J0 is connected to an ATX power supply through an ATX connector; and the J1 is connected to a PCIE slot of the main control board.

[0074] Specifically, refer to Figure 1 It can be seen that the power supply of the main control board is all connected to P0, so correspondingly, J0 of the test carrier board is the power output.

[0075] More specifically, refer to Figure 3 and Figure 4 , Figure 4This is a schematic diagram of the architecture of the test carrier provided in an embodiment of the present application. The ATX power supply supplies power to the entire test carrier via the ATX connector connected to J0 (ATX CONN in the figure), so that J0 outputs 12V and 3.3V voltage signals, where 3.3V is 3V3_AUX (i.e., a 3.3V auxiliary signal source).

[0076] Furthermore, the J1 is connected to the PCIE slot of the main control board.

[0077] Specifically, the J1 connector inputs the PCIE signal to the PCIE slot for connecting test instruments or debugging tools to facilitate functional verification, performance testing, and troubleshooting of the main control board. Through the PCIE bus, the test carrier board can simulate different working environments and load conditions, helping relevant personnel to more accurately evaluate the performance and stability of the main control board.

[0078] Furthermore, one end of the J2 is connected to the RJ45 interface, and the other end is connected to the SFP+ interface.

[0079] Specifically, the J2 connector inputs the MDI (Medium Dependent Interface) signal to the RJ45 connector to support gigabit networks, and inputs the SFP+ (Small Form-factor Pluggable Plus) signal to the optical cage, which supports up to 10G optical modules. The RJ45 is a network interface connector used for Ethernet connections, and the optical cage is a slot or area for installing SFP+ modules, which can support SFP+ optical modules with a maximum speed of 10 Gbps.

[0080] Furthermore, the J3 is respectively connected to multiple connectors of the main control board, and is used for the test carrier board to input USB3.0, SATA3.0, HDMI, CAN, RS232, RS422, RS485 and / or GPIO signals to the main control board.

[0081] Specifically, the J3 connector inputs USB3.0, SATA3.0, HDMI, CAN, RS232, RS422, RS485 and / or GPIO signals to the main control board for testing of multiple connectors.

[0082] Furthermore, the main control card is also provided with a front panel, which includes a reset button, an RJ45 interface, a USB interface, a VGA interface, an indicator light and a J30J serial port.

[0083] About the reset button: It is used to restart the main control card or the entire system. When the system fails or needs to be reinitialized, pressing the reset button can quickly restore the device to factory settings or default state without turning off the power and restarting the device.

[0084] About the RJ45 port: Provides a wired network connection for accessing a local area network or the Internet. Through the RJ45 port, the main control card can communicate with other network devices (such as routers, switches, other computers, etc.) to achieve data transmission and sharing.

[0085] About the USB interface: It is used to connect external USB devices such as keyboard, mouse, storage device (U disk, mobile hard disk), printer, etc. The USB interface provides a universal, plug-and-play connection method, making it easy for users to expand the functions of the main control card and peripheral support.

[0086] About the VGA port: Used to connect to a monitor or projector and provide a video output signal. The VGA port is an analog video interface standard, widely used for connecting computer monitors and projectors, and supports high-resolution video output.

[0087] Indicator lights: These display the operating status and fault information of the main control card. Common indicators include the power indicator, network activity indicator, and USB activity indicator. By observing the color and blinking pattern of the indicator lights, users can understand the operating status and fault conditions of the device.

[0088] About J30J serial port: used for serial communication and connecting external serial devices.
