Description

Single board processing method, single board, device and system

[0001] This application claims priority to Chinese patent application No. 202410029820.7 filed on January 5, 2024, entitled “Single-board processing method, single board, device and system,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the field of communications, and in particular to a single board processing method, single board, device and system. Background Art

[0003] In a chassis device, one device includes multiple boards. These boards may include a power board, a main control board, and an interface board. The interface board may include a first interface, a second interface, and a power switch unit. The main control board is connected to the first interface and is also connected to the second interface. The second interface is also connected to the power switch unit, which is also connected to the power board.

[0004] The power switch unit is closed, allowing the power board to input voltage to the interface board. When voltage is input, the interface board exchanges information with the main control board through the first interface. When the interface board is no longer needed, or when fault isolation is required after a fault on the interface board, the main control board sends a disconnection instruction signal to the second interface. The second interface sends the disconnection instruction signal to the power switch unit. The power switch unit disconnects based on the disconnection instruction signal, causing the power board to stop inputting voltage to the interface board, thereby reducing power consumption or isolating the fault.

[0005] The interface board needs to include a first interface and a second interface, which not only increases the cost but also reduces the integration of the device.

[0006] Summary of the Invention

[0007] This application provides a single board processing method, single board, device and system to reduce costs and improve device integration. The technical solution is as follows:

[0008] In a first aspect, the present application provides a first single board, comprising: an interface, a switching unit and a power switch unit; the interface is used to connect to the second single board, and the interface is also used to connect to the switching unit. The switching unit is used to disconnect the electrical connection between the interface and the power switch unit. The power switch unit is used to connect the electrical connection between the power switch unit and the power board when the electrical connection is disconnected, so that the power board provides input voltage to the first single board. The interface is also used to receive or send information interacting with the second single board when there is voltage input to the first single board. The switching unit is also used to connect the electrical connection between the interface and the power switch unit. The interface is also used to send a disconnect indication signal from the second single board to the power switch unit after receiving the disconnect indication signal, and the disconnect indication signal is used to indicate the disconnection of the electrical connection between the power switch unit and the power board. The power switch unit is also used to disconnect the electrical connection between the power switch unit and the power board based on the disconnect indication signal.

[0009] Since the electrical connection between the interface and the power switch unit can be disconnected through the switching unit, the power switch unit is connected to the electrical connection between the power switch unit and the power board, and then the power board provides input voltage to the first board, and the first board can exchange information with the second board through the interface. Alternatively, the electrical connection between the interface and the power switch unit can be connected through the switching unit, so that the second board can send a disconnection instruction signal to the interface, and the interface sends the disconnection instruction signal to the power switch unit, and the power switch unit disconnects the electrical connection between the power switch unit and the power board based on the disconnection instruction signal. In this way, setting an interface on the first board can complete the information exchange between the first board and the second board, and can also complete the second board controlling the power switch unit on the first board, thereby reducing hardware costs and improving the integration of the equipment.

[0010] In one possible implementation, the interface is further configured to, upon receiving a connection indication signal from the second board, send the connection indication signal to the power switch unit. The connection indication signal indicates that the electrical connection between the power switch unit and the power board is established. The power switch unit is further configured to, based on the connection indication signal, establish the electrical connection between the power switch unit and the power board, so that the power board provides input voltage to the first board. This enables the first board to start up and ensure normal operation of the first board.

[0011] In another possible implementation, the switching unit is a switch, and the first board further includes a processing unit, which is further connected to the switch. The processing unit is configured to control the switch to open to disconnect the electrical connection between the interface and the power switch unit, or to control the switch to close to connect the electrical connection between the interface and the power switch unit.

[0012] In another possible implementation, the switch is a relay, the processing unit is connected to the control terminal of the relay, the input terminal of the relay is connected to the interface, and the output terminal of the relay is connected to the power switch unit, thereby enriching the implementation of the switching unit.

[0013] In another possible implementation, the switch is a metal oxide semiconductor (MOS) transistor, the processing unit is connected to the gate of the MOS transistor, the source of the MOS transistor is connected to the interface, and the drain of the MOS transistor is connected to the power switch unit. This enriches the implementation of the switching unit.

[0014] In another possible implementation, the switch is a transistor, the processing unit is connected to the base of the transistor, the emitter of the transistor is connected to the interface, and the collector of the transistor is connected to the power switch unit, thereby enriching the implementation of the switching unit.

[0015] In another possible implementation, the first board is an interface board, and the second board is a main control board.

[0016] In another possible implementation, the processing unit is a monitoring unit on the first board, and the monitoring unit is used to monitor the first board.

[0017] In another possible implementation, the information includes one or more of the following: status information of the first board or status information of the second board.

[0018] In a second aspect, the present application provides a method for processing a single board, wherein the single board is a first single board, and the first single board includes: an interface, a switching unit, and a power switch unit. In the method, the electrical connection between the interface and the power switch unit is disconnected. In the case where the electrical connection is disconnected, the electrical connection between the power switch unit and the power board is connected so that the power board provides input voltage to the first single board. When there is voltage input to the first single board, information for interacting with the second single board is received or sent through the interface. The electrical connection between the interface and the power switch unit is connected. After receiving the disconnection indication signal sent by the second single board through the interface, the electrical connection between the power switch unit and the power board is disconnected.

[0019] Since the electrical connection between the interface and the power switch unit can be disconnected, the electrical connection between the power switch unit and the power board can be connected, and then the power board can provide input voltage to the first board, information can be exchanged with the second board through the interface. Alternatively, the electrical connection between the interface and the power switch unit can be connected, so that the second board can send a disconnection instruction signal to the interface, and after receiving the disconnection instruction signal through the interface, the electrical connection between the power switch unit and the power board is disconnected. In this way, providing an interface on the first board can complete information exchange between the first and second boards, and can also enable the second board to control the power switch unit on the first board, thereby reducing hardware costs and improving the integration of the device.

[0020] In one possible implementation, a disconnection indication signal is sent to the power switch unit, where the disconnection indication signal is used to indicate disconnection of the electrical connection between the power switch unit and the power board, so that the power switch unit disconnects the electrical connection between the power switch unit and the power board based on the disconnection indication signal.

[0021] In another possible implementation, after receiving the connection indication signal sent by the second board through the interface, the electrical connection between the power switch unit and the power board is connected, so that the power board provides input voltage to the first board. This can start the first board and ensure that the first board can operate normally.

[0022] In another possible implementation, the switching unit is a switch, and the switch is controlled to be open to disconnect the electrical connection between the interface and the power switch unit, or the switch is controlled to be closed to connect the electrical connection between the interface and the power switch unit.

[0023] In another possible implementation, the first board further includes a processing unit for controlling the opening or closing of a switch. The switch is a relay. The processing unit is connected to a control terminal of the relay. The input terminal of the relay is connected to the interface. The output terminal of the relay is connected to the power switch unit. This enriches the implementation methods of the switching unit.

[0024] In another possible implementation, the switch is a metal oxide semiconductor (MOS) transistor, the processing unit is connected to the gate of the MOS transistor, the source of the MOS transistor is connected to the interface, and the drain of the MOS transistor is connected to the power switch unit. This enriches the implementation of the switching unit.

[0025] In another possible implementation, the switch is a transistor, the processing unit is connected to the base of the transistor, the emitter of the transistor is connected to the interface, and the collector of the transistor is connected to the power switch unit, thereby enriching the implementation of the switching unit.

[0026] In another possible implementation, the first board is an interface board, and the second board is a main control board.

[0027] In another possible implementation, the processing unit is a monitoring unit on the first board, and the monitoring unit is used to monitor the first board.

[0028] In another possible implementation, the information exchanged between the processing unit and the second board includes one or more of the following: status information of the first board or status information of the second board.

[0029] In a third aspect, the present application provides a device, comprising the first board in the above-mentioned first aspect or any possible implementation of the first aspect.

[0030] In a fourth aspect, the present application provides a multi-board system, which includes the first board, the second board and the power board in the above-mentioned first aspect or any possible implementation of the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The power board 13 is used to input voltage to the first board 11 .

[0052] The first board 11 is configured to perform one or more of the following operations when voltage is input: providing service functions or performing information exchange with the second board 12 .

[0053] The second board 12 is used to manage the first board 11 and / or perform information exchange with the first board 11 .

[0054] The operation of the second board 12 managing the first board 11 may be:

[0055] The second board 12 can control the first board 11 to turn on or off. For example, the second board 12 can control the first board 11 to receive the voltage input by the power board 13 to turn on the first board 11; and / or control the first board 11 to stop receiving the voltage input by the power board 13 to turn off the first board 11.

[0056] In some embodiments, when the first board 11 no longer needs to provide the service function, the second board 12 can control the first board 11 to stop receiving voltage input from the power board 13 to reduce power consumption. When the first board 11 is needed to provide the service function, the second board 12 can control the first board 11 to receive voltage input from the power board 13, allowing the first board 11 to provide the service function while receiving voltage input.

[0057] In some embodiments, when the first board 11 fails, the second board 12 can control the first board 11 to stop receiving the voltage input by the power board 13, thereby isolating the first board 11 to achieve fault isolation.

[0058] In some embodiments, the device 10 may include one first board 11 . Alternatively, as shown in FIG. 2 , the device 10 may include multiple first boards 11 .

[0059] For each first single board 11 among the multiple first single boards 11, the first single board 11 is connected to the second single board 12, and the first single board 11 is also connected to the power board 13, the power board 13 inputs the voltage to the first single board 11, and the second single board 12 can manage the first single board 11 and / or interact with the first single board 11 for information, etc.

[0060] In some embodiments, the device 10 may include one second board 12 . Alternatively, the device 10 may include multiple second boards 12 , and each second board 12 may be connected to at least one first board 11 .

[0061] For each second single board 12 , and for at least one first single board 11 connected to the second single board 12 , the second single board 12 is used to manage the at least one first single board 11 and / or perform information exchange with the at least one first single board 11 .

[0062] At least one first single board 11 connected to each second single board 12 may be the same, or at least one first single board 11 connected to each second single board 12 may be different, or at least one first single board 11 connected to each second single board 12 may have some of the same first single boards 11.

[0063] In some embodiments, when multiple second boards 12 are connected to at least one first board 11, one of the multiple second boards 12 is active, and the other second boards 12 are standby. When the active second board 12 is normal, the active second board 12 manages the at least one first board 11 and / or exchanges information with the at least one first board 11. When the active second board 12 fails, the standby second board 12 manages the at least one first board 11 and / or exchanges information with the at least one first board 11.

[0064] In some embodiments, the device 10 may be a frame-type device, etc., the second single board 12 may be a main control board, etc., and the first single board 11 may be an interface board, etc.

[0065] 3 , an embodiment of the present application provides a first board 11 , which may be the first board 11 in the device 10 shown in FIG. 1 or FIG. 2 , including:

[0066] Interface 110, switching unit 111 and power switch unit 112;

[0067] The interface 110 is connected to the second board 12, the interface 110 is also connected to the switching unit 111, the switching unit 111 is also connected to the power switch unit 112, and the power switch unit 112 is also connected to the power board 13;

[0068] The switching unit 111 is used to disconnect the electrical connection between the interface 110 and the power switch unit 112;

[0069] The power switch unit 112 is used to connect the electrical connection between the power switch unit 112 and the power board 13 when the electrical connection is disconnected, so that the power board 13 inputs voltage to the first board 11;

[0070] The interface 110 is used to receive or send information interacting with the second board 12 when the first board 11 has voltage input;

[0071] The switching unit 111 is also used to electrically connect the interface 110 to the power switch unit 112;

[0072] The interface 110 is further configured to receive a disconnection instruction signal sent by the second board 12 and, when the electrical connection is established, send the disconnection instruction signal to the power switch unit 112, whereby the disconnection instruction signal is used to instruct to disconnect the electrical connection between the power switch unit 112 and the power board 13;

[0073] The power switch unit 112 is further configured to disconnect the electrical connection between the power switch unit 112 and the power board 13 based on the disconnection indication signal.

[0074] In some embodiments, the input end of the power switch unit 112 is connected to the output end of the power board 13, the output end of the power switch unit 112 is connected to at least one device in the first single board 11 (such as the processing unit 113 in Figure 4), the control end of the power switch unit 112 is connected to the output end of the switching unit 111, and the input end of the switching unit 111 is connected to the interface 110.

[0075] In some embodiments, the input end of the power switch unit 112 is connected to the output end of the power board 13 through a power bus.

[0076] In some embodiments, the switching unit 111 can disconnect the electrical connection between the interface 110 and the control terminal of the power switch unit 112, thereby eliminating the need for a signal input to the control terminal of the power switch unit 112. When no signal is input to the control terminal of the power switch unit 112, the power switch unit 112 is in a closed state, connecting the electrical connection between the power switch unit 112 and the power board 13. This allows the voltage from the power board 13 to be input to the first board 11, thereby enabling the power board 13 to input voltage to the first board 11, thereby turning on the first board 11. When receiving voltage input, the first board 11 exchanges information with the second board 12 via the interface 110.

[0077] Optionally, when there is voltage input, the first board 11 sends information to the second board 12 through the interface 110 , and / or receives information sent by the second board 12 through the interface 110 .

[0078] In some embodiments, the switching unit 111 can electrically connect the interface 110 to the control terminal of the power switch unit 112. The second board 12 can send a disconnection instruction signal to the interface 110. The interface 110 transmits the disconnection instruction signal to the control terminal of the power switch unit 112, which then receives the disconnection instruction signal. Under the control of the disconnection instruction signal, the power switch unit 112 is in an off state, disconnecting the electrical connection between the power switch unit 112 and the power board 13, thereby stopping the voltage from the power board 13 from being input to the first board 11, thereby shutting down the first board 11. In the absence of voltage input, the first board 11 stops exchanging information with the second board 12 through the interface 110.

[0079] The so-called electrical connection between the power switch unit 112 and the power board 13 is connected, which means that when the power switch unit 112 is closed, the circuit for transmitting voltage from the power board 13 to the first board 11 is connected. The so-called electrical connection between the power switch unit 112 and the power board 13 is disconnected, which means that when the power switch unit 112 is disconnected, the circuit for transmitting voltage from the power board 13 to the first board 11 is disconnected.

[0080] Optionally, after the first board 11 is turned off, because the switching unit 111 continues to maintain the electrical connection between the interface 110 and the control end of the power switch unit 112, the second board 12 continues to send a disconnection instruction signal to the interface 110, and the interface 110 continues to send the disconnection instruction signal to the control end of the power on control unit 112. Under the control of the disconnection instruction signal, the power switch unit 112 remains in the disconnected state, thereby keeping the first board 11 in the turned-off state.

[0081] In some embodiments, the disconnection indication signal may be a high level signal.

[0082] In some embodiments, with respect to the power switch unit 112, when the switching unit 111 disconnects the electrical connection between the interface 110 and the control terminal of the power switch unit 112, no signal is input to the control terminal of the power switch unit 112, and the power switch unit 112 is closed, thereby placing the power switch unit 112 in a closed state and establishing the electrical connection between the power switch unit 112 and the power board 13, thereby inputting the voltage from the power board 13 into the first board 11. When the switching unit 111 establishes the electrical connection between the interface 110 and the control terminal of the power switch unit 112, if the disconnection indication signal is input to the control terminal of the power switch unit 112, the power switch control signal unit 112 is disconnected, thereby placing the power switch unit 112 in a disconnected state and disconnecting the power switch unit 112 from the power board 13, thereby stopping the voltage from the power board 13 from being input into the first board 11, thereby shutting down the first board 11.

[0083] Since the first single board 11 includes a switching unit 111, the switching unit 111 is connected to the interface 110, and the switching unit 111 is also connected to the power switch unit 112, the switching unit 111 can disconnect the electrical connection between the interface 110 and the power switch unit 112, and the power switch unit 112 connects the electrical connection between the power board 13 and the power switch unit 112, so that the power board 13 inputs voltage to the first single board 11, and the first single board 11 exchanges information with the second single board 12 through the interface 110, thereby ensuring the normal operation of the first single board 11. The switching unit 111 can also connect the electrical connection between the interface 110 and the power switch unit 112, so that the second single board 12 can send a disconnection instruction signal to the interface 110, and the interface 110 sends the disconnection instruction signal to the power switch unit 112. The power switch unit 112 disconnects the electrical connection between the power board 13 and the power switch unit 112 based on the disconnection instruction signal to stop inputting the voltage from the power board 13 to the first unit 11, thereby controlling the power switch unit 112 to control the first single board 11 to shut down. In this way, providing an interface 110 between the first single board 11 and the second single board 12 can complete the information exchange between the first single board 11 and the second single board 12, and can also complete the second single board 12 controlling the power switch unit 112 on the first single board 11, thereby saving hardware costs and improving the integration of the device 10.

[0084] After the first board 11 is shut down, if the first board 11 needs to be started, since the switching unit 111 establishes the electrical connection between the interface 110 and the control end of the power switch unit 112, the second board 12 can send a connection indication signal to the interface 110. The connection indication signal is used to indicate that the electrical connection between the power switch unit 112 and the power board 13 is established.

[0085] The interface 110 is further configured to receive the connection indication signal sent by the second board 12 and send the connection indication signal to the power switch unit 112;

[0086] The power switch unit 112 is further configured to connect the electrical connection between the power switch unit 112 and the power board 13 based on the connection indication signal, so that the power board 13 inputs voltage to the first board 11 .

[0087] In some embodiments, the control end receiving interface 110 of the power switch unit 112 sends a connectivity indication signal from the second single board 12, and the power switch unit 112 is closed based on the connectivity indication signal. The power switch unit 112 is in a closed state to connect the electrical connection between the power switch unit 112 and the power board 13 and input the voltage from the power board 13 into the first single board 11, thereby turning on the first single board 11.

[0088] When there is voltage input, the first board 11 can perform information exchange and other operations with the second board 12 through the interface 110 .

[0089] Optionally, the information exchanged between the first board 11 and the second board 12 may include one or more of the following: status information of the first board 11 or status information of the second board 12 , etc.

[0090] In some embodiments, referring to FIG4 , the first board 11 further includes a processing unit 113, which is connected to the output end of the power switch unit 112 and is further connected to the interface 110. When the power switch unit 112 is in a closed state, the voltage from the power board 13 can be input to the processing unit 113.

[0091] When voltage is input, the processing unit 113 exchanges information with the second board 12 through the interface 110. Specifically, when voltage is input, the processing unit 113 may send status information of the first board 11 to the interface 110, and the interface 110 may send the status information to the second board 12. Alternatively, the interface 110 may receive status information of the second board 12 from the second board 12, send the status information to the processing unit 113, and the processing unit 113 may receive the status information.

[0092] In some embodiments, the second unit 12 may include an interface, through which it is connected to the interface 110 included in the first board 11. The second board 12 may include a processing unit, and the operation of the processing unit 113 in the first board 11 and the second board 12 exchanging information may be: the processing unit 113 in the first board 11 exchanges information with the processing unit in the second board 12.

[0093] Optionally, the processing unit 113 may be a monitoring unit configured to monitor the first board 11. Optionally, the status information of the first board 11 may be monitoring status information obtained by the processing unit 113 by querying the first board 11.

[0094] Optionally, the monitoring status information may be basic working conditions of the first board 11 obtained by querying the processing unit 113. For example, the monitoring status information includes one or more of the following information: voltage, clock, system power on and off control, temperature monitoring or fan control, etc.

[0095] Optionally, the processing unit in the second board 12 may be a monitoring unit configured to monitor the second board 12. Optionally, the status information of the second board 12 may be monitoring status information obtained by querying the second board 12 by the processing unit in the second board 12.

[0096] Optionally, the monitoring status information of the second single board 12 may be the basic working conditions of the second single board 12 obtained by querying the processing unit in the second single board 12. For example, the monitoring status information of the second single board 12 includes one or more of the following information: voltage, clock, system power on and off control, temperature monitoring or fan control, etc.

[0097] In some embodiments, the disconnection indication signal may be a high-level signal, and the connection indication signal may be a low-level signal, etc. Of course, the disconnection indication signal being a low-level signal and the connection indication signal being a high-level signal can also control the power switch unit 112 to be closed or opened, which will not be described in detail here.

[0098] 5 , the switching unit 111 may be a switch 111 , and the processing unit 113 is also connected to the switch 111 ;

[0099] The processing unit 113 is configured to control the switch 111 to be opened to disconnect the electrical connection between the interface 110 and the power switch unit 112 , or to control the switch 111 to be closed to connect the electrical connection between the interface 110 and the power switch unit 112 .

[0100] In some embodiments, the processing unit 113 is also connected to the control end of the switch 111 , so that the processing unit 113 can control the switch 111 to be opened or closed.

[0101] When the processing unit 113 requires the power switch unit 112 to be disconnected, that is, when the power switch unit 112 needs to stop inputting voltage from the power board 13 to the processing unit 113, the processing unit 113 controls the switch 111 to be closed, and then the second board 12 sends a disconnection instruction signal to the interface 110. The interface 110 sends the disconnection instruction signal to the power switch unit 112 and the processing unit 113. Because the processing unit 113 knows that the power switch unit 112 needs to be disconnected, even if the processing unit 113 receives the disconnection instruction signal and discards it, it will not affect the processing unit 113.

[0102] After the power switch unit 112 is disconnected, since there is no voltage input to the processing unit 113 , the processing unit 113 does not work and does not receive the disconnection indication signal sent by the interface 110 .

[0103] When there is no voltage input to the processing unit 113 , the switch 111 is in a continuously closed state even without the control of the processing unit 113 , ie, the electrical connection between the interface 110 and the voltage switch control unit 112 is continuously maintained.

[0104] When voltage is input to the processing unit 113, the processing unit 113 can control the switch 111 to open, thereby disconnecting the electrical connection between the interface 110 and the power switch unit 112. After the electrical connection between the interface 110 and the power switch unit 112 is disconnected, since no signal is input to the control terminal of the power switch unit 112, the power switch unit 112 remains in a closed state, and the voltage from the power board 13 is continuously input to the processing unit 113.

[0105] In some embodiments, the interface 110 may be a pin on the first board 11 , and the pin may be connected to the processing unit 113 and the switching unit (eg, switch) 111 through a signal line.

[0106] In some embodiments, referring to FIG. 6 , the switch 111 is a relay 111 , the processing unit 113 is connected to a control end of the relay 111 , an input end of the relay 111 is connected to the interface 110 , and an output end of the relay 111 is connected to the power switch unit 112 .

[0107] Optionally, the default state of the relay 111 is the closed state. When the processing unit 113 requires the relay 111 to be disconnected, a high-level signal can be input to the control end of the relay 111. The relay 111 is disconnected under the control of the high-level signal to disconnect the electrical connection between the interface 110 and the power switch unit 112.

[0108] When the processing unit 113 requires the relay 111 to be closed, it can stop inputting signals to the control terminal of the relay 111. The relay 111 will then automatically close after returning to its default state, thereby establishing an electrical connection between the interface 110 and the power switch unit 112. When the power switch unit 112 stops inputting voltage to the processing unit 113, since the processing unit 113 stops operating, it will not send any signals to the relay 111. The relay 111 will remain in its default state, i.e., remain closed, thereby maintaining an electrical connection between the interface 110 and the power switch unit 112.

[0109] In some embodiments, referring to FIG. 7 , the switch 111 is a metal oxide semiconductor (MOS) transistor 111 , the processing unit 113 is connected to the gate of the MOS transistor 111 , the source of the MOS transistor 111 is connected to the interface 110 , and the drain of the MOS transistor 111 is connected to the power switch unit 112 .

[0110] Optionally, referring to FIG. 7 , the gate of the MOS transistor 111 is further connected to one end of a resistor R, and the other end of the resistor R is connected to the ground terminal GND.

[0111] Optionally, when the processing unit 113 needs to disconnect the MOS transistor 111 , a high-level signal may be input to the gate of the MOS transistor 111 , and the source and drain of the MOS transistor 111 are disconnected to disconnect the electrical connection between the interface 110 and the power switch unit 112 .

[0112] When the processing unit 113 requires the MOS transistor 111 to be closed, it can stop inputting signals to the gate of the MOS transistor 111. When the second single board 12 needs to control the power switch unit 112 to be open, it inputs a high-level signal to the interface 110. The interface 110 transmits this high-level signal to the source of the MOS transistor 111. The voltage between the source and the gate of the MOS transistor 111 increases, thereby causing the source and drain of the MOS transistor 111 to be conductive, thereby establishing an electrical connection between the interface 110 and the power switch unit 112.

[0113] When the power switch unit 112 stops inputting voltage to the processing unit 113, since the processing unit 113 stops working, no signal is sent to the MOS tube 111. The second single board 12 continues to send a high-level signal, and the source and drain of the MOS tube 111 continue to be turned on to continuously connect the electrical connection between the interface 110 and the power switch unit 112.

[0114] In some embodiments, referring to FIG. 8 , the switch 111 is a transistor 111 , the processing unit 113 is connected to the base of the transistor 111 , the emitter of the transistor 111 is connected to the interface 110 , and the collector of the transistor 111 is connected to the power switch unit 112 .

[0115] Optionally, referring to FIG. 8 , the base of the transistor 111 is further connected to one end of a resistor R, and the other end of the resistor R is connected to the ground terminal GND.

[0116] Optionally, when the processing unit 113 needs to disconnect the transistor 111, a high-level signal can be input to the base of the transistor 111 to disconnect the emitter and collector of the transistor 111 to disconnect the electrical connection between the interface 110 and the power switch unit 112.

[0117] When the processing unit 113 needs to close the transistor 111, it can stop inputting signals to the base of the transistor 111. When the second board 12 needs to control the power switch unit 112 to be turned off, it inputs a high-level signal to the interface 110. The interface 110 transmits this high-level signal to the emitter of the transistor 111. The voltage between the emitter and base of the transistor 111 increases, thereby turning on the emitter and collector of the transistor 111, thereby establishing an electrical connection between the interface 110 and the power switch unit 112.

[0118] When the power switch unit 112 stops inputting voltage to the processing unit 113, since the processing unit 113 stops working, no signal is sent to the transistor 111. The second single board 12 continues to send a high-level signal, and the emitter and collector of the transistor 111 continue to be turned on to continuously connect the electrical connection between the interface 110 and the power switch unit 112.

[0119] In some embodiments, referring to FIG. 4 , the first board 11 further includes a first voltage conversion unit 114 , an input end of the first voltage conversion unit 114 is connected to an output end of the power switch unit 112 , and an output end of the first voltage conversion unit 114 is connected to the processing unit 113 .

[0120] The voltage value of the power supply board 13 may not be equal to the voltage value required for the processing unit 113 to operate. Therefore, the power switch unit 112 cannot directly input the voltage from the power supply board 13 to the processing unit 113. Therefore, the first voltage conversion unit 114 is required to convert the voltage from the power supply board 13 and input the converted voltage to the processing unit 113.

[0121] For ease of explanation, the voltage input from the power switch unit 112 to the first voltage conversion unit 114 is referred to as a first voltage. That is, the power switch unit 112 inputs the first voltage from the power board 13 to the first voltage conversion unit 114. The first voltage conversion unit 114 converts the first voltage into a second voltage, the voltage value of which may be equal to the voltage value required for the operation of the processing unit 113, and inputs the second voltage to the processing unit 113.

[0122] For example, the first voltage is 48 volts, and the second voltage required for the normal operation of the processing unit 113 is 3.3 volts. In this way, the first voltage conversion unit 114 is used to convert the first voltage of 48 volts into a second voltage of 3.3 volts and input the second voltage of 3.3 volts to the processing unit 113.

[0123] For another example, the first voltage is 48 volts, and the second voltage required for the normal operation of the processing unit 113 is 1.2 volts. In this way, the first voltage conversion unit 114 is used to convert the first voltage of 48 volts into a second voltage of 1.2 volts and input the second voltage of 1.2 volts to the processing unit 113.

[0124] Optionally, the first voltage conversion unit 114 may be a device such as a transformer.

[0125] In some embodiments, the first voltage conversion unit 114 may convert the first voltage into a plurality of second voltages having different voltage values, and input the plurality of second voltages to the processing unit 113 to meet the needs of the processing unit 113. For example, the first voltage conversion unit 114 may convert a first voltage of 48 volts into a second voltage of 3.3 volts, a second voltage of 1.2 volts, and a second voltage of 0.8 volts, and input the second voltages of 3.3 volts, 1.2 volts, and 0.8 volts to the processing unit 113.

[0126] In some embodiments, referring to FIG9 , the first board 11 further includes: a functional circuit 115 , and the power switch unit 112 is further connected to the functional circuit 115 ;

[0127] When the switching unit 111 disconnects the electrical connection between the interface 110 and the power switch unit 112 , the power switch unit 112 is also used to input the voltage from the power board 13 to the functional circuit 115 , and the functional circuit 115 is used to implement the business functions that the first single board 11 needs to provide.

[0128] 9 , the output end of the power switch unit 112 is connected to the input end of the functional circuit 115 . The power switch unit 112 inputs voltage to the functional circuit 115 , and the functional circuit 115 implements the service function when there is voltage input.

[0129] For example, the service function may be a communication interface, i.e., the functional circuit 115 provides a communication interface to the user when voltage is input. For example, if the communication interface is an Ethernet interface, the functional circuit 115 provides an Ethernet interface to the user when voltage is input. For another example, if the communication interface is a passive optical network (PON) interface, the functional circuit 115 provides a PON interface to the user when voltage is input.

[0130] For another example, the service function may be a storage function, that is, the functional circuit 115 provides the user with a storage function when there is a voltage input.

[0131] In some embodiments, referring to FIG. 9 , the first board 11 further includes a second voltage conversion unit 116 , an input end of the second voltage conversion unit 116 is connected to an output end of the power switch unit 112 , and an output end of the second voltage conversion unit 116 is connected to the functional circuit 115 .

[0132] The voltage value of the power supply board 13 may not be equal to the voltage value required for the functional circuit 115 to operate. Therefore, the power switch unit 112 cannot directly input the voltage from the power supply board 13 to the functional circuit 115. Therefore, the second voltage conversion unit 116 is required to convert the voltage from the power supply board 13 and input the converted voltage to the functional circuit 115.

[0133] For ease of explanation, the voltage input from the power switch unit 112 to the first voltage conversion unit 114 is referred to as a first voltage. That is, the power switch unit 112 inputs the first voltage from the power board 13 to the second voltage conversion unit 116. The second voltage conversion unit 116 converts the first voltage into a third voltage, the value of which may be equal to the voltage required for the operation of the functional circuit 115, and inputs the third voltage to the functional circuit 115.

[0134] For example, the first voltage is 48 volts, and the third voltage required for the functional circuit 115 to work normally is 5 volts. In this way, the second voltage conversion unit 116 is used to convert the first voltage of 48 volts into a third voltage of 5 volts and input the third voltage of 5 volts to the processing unit 113.

[0135] For another example, the first voltage is 48 volts, and the third voltage required for the functional circuit 115 to work normally is 1.8 volts. In this way, the second voltage conversion unit 116 is used to convert the first voltage of 48 volts into a third voltage of 1.8 volts and input the third voltage of 1.8 volts to the processing unit 113.

[0136] Optionally, the second voltage conversion unit 116 may be a device such as a transformer.

[0137] In some embodiments, the second voltage conversion unit 116 may convert the first voltage into a plurality of third voltages having different voltage values, and input the plurality of third voltages to the functional circuit 115 to meet the requirements of the functional circuit 115. For example, the second voltage conversion unit 116 may convert a first voltage of 48 volts into a third voltage of 5 volts and a third voltage of 1.8 volts, and input the third voltage of 5 volts and the third voltage of 1.8 volts to the functional circuit 115.

[0138] In some embodiments, referring to FIG10 , the first single board 11 further includes a third voltage conversion unit 117 , the input end of the third voltage conversion unit 117 is connected to the output end of the power switch unit 112 , and the output end of the third voltage conversion unit 117 is connected to the input end of the first voltage conversion unit 114 and the input end of the second voltage conversion unit 116 .

[0139] The power switch unit 112 inputs the first voltage from the power board 13 to the third voltage conversion unit 117 . The third voltage conversion unit 117 converts the first voltage into a fourth voltage and inputs the fourth voltage to the first voltage conversion unit 114 and the second voltage conversion unit 116 .

[0140] The first voltage conversion unit 114 converts the fourth voltage into a second voltage and inputs the second voltage to the processing unit 113. The second voltage conversion unit 116 converts the fourth voltage into a third voltage and inputs the third voltage to the functional circuit 115.

[0141] The voltage value of the first voltage may be large. Compared with the voltage value of the first voltage, the voltage values ​​of the second voltage and the third voltage are small. If the first voltage conversion unit 114 is directly used to convert the first voltage into the second voltage, and / or the second voltage conversion unit 116 is directly used to convert the first voltage into the third voltage, it may be necessary to perform multiple power supply isolation conversions in the first single board 11, which increases the size and circuit complexity of the first single board 11, resulting in high cost.

[0142] To this end, a third voltage conversion unit 117 can be added to the first board 11. The third voltage conversion unit 117 converts the first voltage into a fourth voltage with a smaller voltage value, and the fourth voltage is input to the first voltage conversion unit 114 and the second voltage conversion unit 116. The first voltage conversion unit 114 then converts the fourth voltage into the second voltage, and the second voltage conversion unit 116 converts the fourth voltage into the third voltage. This provides a power supply isolation conversion within the first board 11, reducing the size of the first board 11, lowering circuit complexity, and reducing costs.

[0143] For example, the first voltage is 48 volts, the fourth voltage is 12 volts, the second voltage required for normal operation of the processing unit 113 is 3.3 volts, and the third voltage required for normal operation of the functional circuit 115 is 5 volts. Thus, the third voltage conversion unit 117 is configured to convert the first voltage of 48 volts into a fourth voltage of 12 volts, and input the 12 volt fourth voltage to the first voltage conversion unit 114 and the second voltage conversion unit 116. The first voltage conversion unit 114 is configured to convert the 12 volt fourth voltage into a second voltage of 3.3 volts, and input the 3.3 volt second voltage to the processing unit 113. The second voltage conversion unit 116 is configured to convert the 12 volt fourth voltage into a third voltage of 5 volts, and input the 5 volt third voltage to the functional circuit 115.

[0144] For another example, the first voltage remains at 48 volts, the fourth voltage remains at 12 volts, the second voltage required for normal operation of the processing unit 113 is 1.2 volts, and the third voltage required for normal operation of the functional circuit 115 is 1.8 volts. Thus, the third voltage conversion unit 117 is configured to convert the first voltage of 48 volts into a fourth voltage of 12 volts, and input the fourth voltage of 12 volts to the first voltage conversion unit 114 and the second voltage conversion unit 116. The first voltage conversion unit 114 is configured to convert the fourth voltage of 12 volts into a second voltage of 1.2 volts, and input the second voltage of 1.2 volts to the processing unit 113. The second voltage conversion unit 116 is configured to convert the fourth voltage of 12 volts into a third voltage of 1.8 volts, or input the third voltage of 1.8 volts to the functional circuit 115.

[0145] In some embodiments, referring to FIG11 , the first single board 11 further includes a power switch 118 , the output end of the power switch unit 112 is connected to the power switch 118 , the power switch 118 is also connected to the input end of the second voltage conversion unit 116 , and the processing unit 113 is also connected to the control end of the power switch 118 .

[0146] The processing unit 113 may send a control signal to the power switch 118 to control the power switch 118 to open or close. When the power switch 118 is closed, the power switch unit 112 may input the first voltage from the power board 13 to the second voltage conversion unit 116. When the power switch 118 is open, the power switch unit 112 may stop inputting the first voltage from the power board 13 to the second voltage conversion unit 116.

[0147] In some embodiments, referring to FIG. 12 , the output end of the third voltage conversion unit 117 is connected to the power switch 118 , the power switch 118 is also connected to the input end of the second voltage conversion unit 116 , and the processing unit 113 is also connected to the control end of the power switch 118 .

[0148] The processing unit 113 may send a control signal to the power switch 118 to control the power switch 118 to open or close. When the power switch 118 is closed, the third voltage conversion unit 117 may input the fourth voltage to the second voltage conversion unit 116; when the power switch 118 is open, the third voltage conversion unit 117 may stop inputting the fourth voltage to the second voltage conversion unit 116.

[0149] In an embodiment of the present application, since the switching unit is connected to the interface and the power switch unit, the switching unit can disconnect the electrical connection between the interface and the power switch unit, closing the power switch unit and thereby allowing the voltage from the power board to be input to the processing unit. At this point, the processing unit exchanges information with the second board via a signal line, thereby ensuring the normal operation of the processing unit, i.e., ensuring that the normal operation of the first board is not affected. The switching unit can also connect the electrical connection between the processing unit and the power switch unit, so that the second board can send a disconnection instruction signal to the power switch unit via the interface. The power switch unit receives the disconnection instruction signal and, based on the disconnection instruction signal, stops inputting the voltage from the power board to the processing unit, thereby controlling the power switch unit and shutting down the first board. Thus, providing an interface on the first board and an interface on the second board can facilitate information exchange between the processing unit and the second board, and can also enable the second board to control the power switch unit on the first board. Therefore, providing an interface on the first board and an interface on the second board can save hardware costs and improve the integration of the device.

[0150] Referring to FIG13 , an embodiment of the present application provides a single board processing method 1300 , which is used to manage a first single board, the first single board including: an interface, a switching unit, and a power switch unit. The first single board may be the first single board provided in the embodiment shown in FIG3 , FIG4 , FIG5 , FIG9 , FIG10 , FIG11 , or FIG12 . The method 1300 includes:

[0151] Step 1301: Disconnect the electrical connection between the interface and the power switch unit.

[0152] Step 1302: Connect the electrical connection between the power switch unit and the power board so that the power board provides input voltage to the first board.

[0153] Step 1303: When voltage is input to the first board, information for interaction with the second board is received or sent through the interface.

[0154] Step 1304: Establish electrical connection between the communication interface and the power switch unit.

[0155] Step 1305: After receiving the disconnection instruction signal sent by the second board through the interface, disconnect the electrical connection between the power switch unit and the power board.

[0156] In some embodiments, a disconnect indication signal is sent to the power switch unit, which is used to indicate the disconnection of the electrical connection between the power switch unit and the power board, so that the power switch unit disconnects the electrical connection between the power switch unit and the power board based on the disconnect indication signal.

[0157] In some embodiments, after receiving a connection indication signal from the second board through the interface, the electrical connection between the power switch unit and the power board is connected, so that the power board provides input voltage to the first board.

[0158] Optionally, after disconnecting the electrical connection between the power switch unit and the power board, a connection indication signal sent by the second board may be received through the interface, and then the connection indication signal may be sent to the power switch unit, where the connection indication signal is used to indicate that the electrical connection between the power switch unit and the power board is restored.

[0159] The power switch unit connects the electrical connection between the power switch unit and the power board based on the connection indication signal, so that the power board provides input voltage to the first board.

[0160] In some embodiments, the switching unit is a switch, which is controlled to be open to disconnect the electrical connection between the interface and the power switch unit, or to be controlled to be closed to connect the electrical connection between the interface and the power switch unit.

[0161] In some embodiments, the first board also includes a processing unit for controlling the switch to open or close, the switch is a relay, the processing unit is connected to the control end of the relay, the input end of the relay is connected to the interface, and the output end of the relay is connected to the power switch unit.

[0162] In some embodiments, the switch is a MOS transistor, the processing unit is connected to the gate of the MOS transistor, the source of the MOS transistor is connected to the interface, and the drain of the MOS transistor is connected to the power switch unit.

[0163] In some embodiments, the switch is a transistor, the processing unit is connected to the base of the transistor, the emitter of the transistor is connected to the interface, and the collector of the transistor is connected to the power switch unit.

[0164] In some embodiments, the first board is an interface board, and the second board is a main control board.

[0165] In some embodiments, the processing unit is a monitoring unit on the first board.

[0166] In some embodiments, the information includes one or more of the following: status information of the first board or status information of the second board.

[0167] In an embodiment of the present application, since the electrical connection between the interface and the power switch unit can be disconnected, the electrical connection between the power board and the power switch unit can be connected, so that the power board provides input voltage to the first single board. When the first single board has voltage input, information exchange can be carried out with the second single board through the interface, thereby ensuring the normal operation of the first single board. Alternatively, the electrical connection between the interface and the power switch unit can be connected, so that the second single board can send a disconnection instruction signal to the power switch unit through the interface, and after receiving the disconnection instruction signal through the interface, the electrical connection between the voltage switch control unit and the power board is disconnected, so that the voltage board stops providing input voltage to the first single board, thereby controlling the power switch unit and controlling the first single board to shut down. In this way, setting an interface on the first single board can complete the information exchange between the first single board and the second single board, and can also complete the second single board controlling the power switch unit on the first single board, thereby reducing hardware costs and improving the integration of the device.
