[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the implementation methods of the present invention are not limited thereto.

They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.
[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "open", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:
[0025] Example 1
[0026] At present, the VPX chassis on the market generally connect the mainboard with IPMI interface to other independent boards with IPMI interface through IPMB bus, so as to realize power-on control and health management of all independent boards in the chassis. Figure 1 As shown, the mainboard with an IPMI interface is directly connected to the IPMB bus through the IPMI interface, and other independent boards are also directly connected to the IPMB bus through IPMC. The IPMB is managed by an intelligent platform and is transmitted in the form of I2C. The IPMC is an onboard intelligent platform management controller. The mainboard with an IPMI interface is used as the host, and other independent boards are used as slaves. Power-on, voltage detection, temperature monitoring, fan control and other operations are performed on other independent boards, and the collected information is then uploaded to the PC.
[0027] Among them, Figure 2As shown, a mainboard with an IPMI interface is used as a host, and the mainboard has a built-in CPU module, so that the CPU module has a CHMC as the general management controller of the intelligent platform, and other independent boards may include a GPU module, a DSP module, an acquisition module, a switching module, a storage module, etc., and each module has an IPMC, so that the CHMC in the CPU module is connected to the IPMC in each module through the IPMB bus.
[0028] The above method of using a motherboard with an IPMI interface as a host has certain limitations, because the motherboard used as the host in the above method must have an IPMI interface, but there are many motherboards on the market that do not have an IPMI interface, such as X86 architecture motherboards, and these motherboards without IPMI interfaces cannot be directly connected to other independent boards through the IPMB bus. Therefore, when the above method is adopted, the optional range of the motherboard will be reduced when selecting the motherboard, and the motherboard cannot be flexibly adapted according to project requirements.
[0029] Therefore, the utility model provides a board detection device with peripheral wind control, which uses the fan board with a control module in the prior art as a wind control board, that is, the control module replaces the main board as the host of the IPMB bus to manage the board, and the main board is connected to the wind control board through a serial port, so that the wind control board reports data to the PC through the main board, which can not only avoid the selection restrictions on the main board, but also facilitate the maintenance of the control module. For example, in the prior art, a BMC controller is also used for current fan control, so the BMC of the wind control board is used as the host of the IPMB to replace the main control to perform board power-on control, health management, information reading, etc.
[0030] In this embodiment, the implementation method is: develop a board - wind control board, as the host of IPMB, all power-on control, health management, information reading, etc. are sent or received by the wind control board through IPMB, and then the MCU on the wind control board reports the obtained results to the main control board through the serial port.
[0031] The advantages of doing so are: ① Placing BMC control on the wind control board reduces restrictions on the selection of the mainboard and provides a wider range of options; ② For companies that make chassis, most of the time the main control module is an outsourced module, and once a problem occurs, it requires FAE support, and the maintenance cost is relatively high. The management module is on a self-developed board, which is more maintainable. ③ The developed wind control board can be used as an independent wind control management device and can be used in multiple chassis.
[0032] Specifically, Figure 3 , Figure 4As shown, a board detection device with peripheral wind control includes a backplane, an IPMB bus is integrated on the backplane, and a plurality of independent boards are connected to the backplane through the IPMB bus. It also includes a wind control board and a main board connected to the wind control board. An MCU control module is arranged on the wind control board. The MCU control module on the wind control board is connected to the IPMB bus and is communicatively connected to the plurality of independent boards through the IPMB bus. A serial port is arranged on the MCU control module and is communicatively connected to the main board through the serial port.
[0033] Preferably, the wind control board is provided with an IPMI interface, so that the wind control board is connected to the IPMB bus through the IPMI interface, so that several independent boards report the working status parameters to the MCU control module through the IPMB bus. The purpose is to use the wind control board as the main board, connect the IPMI interface on the wind control board to the IPMB bus, and obtain the working status parameters of several independent boards through the IPMB bus.
[0034] Preferably, the independent board is arranged on a backplane, a J30J connector is arranged on the backplane, and the independent board is connected to the IPMB bus on the backplane via the J30J connector, so as to facilitate the independent board to be connected to the backplane via the J30J connector.
[0035] Preferably, the mainboard is provided with an Internet port, which is connected to the host computer through the Internet port, so that the mainboard reports the data processed by the MCU control module to the host computer through the Internet port. The purpose is to upload the monitoring data to the host computer through the Internet port in real time.
[0036] Preferably, the MCU control module includes:
[0037] The board power-on module obtains the power supply demand values of several independent boards through the IPMB bus and controls the power on and off of the independent boards. The purpose is to control the power on and off of the independent boards through the IPMB bus.
[0038] Preferably, the MCU control module includes:
[0039] The board information update module stores and reports the card slot number and version information of the independent board, with the purpose of collecting the board information of the independent board through the IPMB bus.
