The features and implementations of the present disclosure are described in detail below with reference to the drawings.

Please refer to "Figure 1" for a schematic view of the cabinet of the present disclosure. The cabinet 100 includes a plurality of main power supplies 110_1~110_N, a plurality of backup power supplies 120_1~120_N, a plurality of nodes 130_1~130_M, a Rack Management Controller (RMC) 140, and a control unit 150, where M is a positive integer greater than 1, and N and M may be the same or different.

The main power supplies 110_1~110_N are used to respectively provide an operating voltage. That is, when the main power supplies 110_1 110 110_N are in a normal state, for example, as a main operating voltage for providing the cabinet 100.

The backup power supplies 120_1~120_N are used to respectively provide an operating voltage. That is to say, when the backup power supplies 120_1~120_N are in a normal state, for example, as an operating voltage for providing the cabinet 100 for standby. That is, when all of the main power supplies 110_1~110_N are abnormal, the backup power supplies 120_1~120_N provide the operating voltage of the cabinet 100, so that the cabinet 100 can still operate normally.

In this embodiment, the maximum power supply values that the primary power supply 110_1~110_N and the backup power supply 120_1~120_N can provide are the same. The power value should be, for example, 500W. Also, the primary power supplies 110_1~110_N are different from the input sources received by the backup power supplies 120_1~120_N. For example, the input sources received by the primary power supplies 110_1 110 110_N are, for example, mains, and the input sources received by the backup power supplies 120_1 120 120_N are, for example, batteries or other energy storage components.

Nodes 130_1~130_M are used to provide power information separately. Further, the nodes 130_1~130_M each include, for example, a Baseboard Management Controller (BMC) and a connection interface. The baseboard management controller is configured to detect the operating states of the nodes 130_1~130_M to provide power information of the nodes 130_1~130_M. The power information is, for example, the voltage, current, and power consumption of the nodes 130_1~130_M.

In this embodiment, the connection interface is, for example, an Inter Integrate Circuit (I2C) bus, a Serial Peripheral Interface (SPI) bus, and a General Purpose Input Output (GPIO) bus.

The rack management controller 140 can be coupled to the baseboard management controllers of the nodes 130_1~130_M through the foregoing connection interface for receiving power information (that is, voltage, current, power consumption, etc. of each node 130_1~130_M), and according to the power information. The total power consumption values of the nodes 130_1~130_M are calculated.

Next, the rack management controller 140 calculates the number of power supply ons based on the total power consumption value and the maximum power supply value of the single power supply. Wherein, the maximum power supply value of the foregoing single power supply is, for example, 500W. Further, electricity The source supply open quantity is, for example, the total power consumption value divided by the maximum power supply value of a single power supply.

In an embodiment, assuming that the total power consumption value is 1400 W and the maximum power supply value of the single power supply is 500 W, the rack management controller 140 performs the total power consumption value and the maximum power supply value of the single power supply. Calculate to calculate 1400W/500W=2.8, that is, the power supply is turned on by 2.8 units. However, since the power supply does not only open 0.8 units, the cabinet management controller 140 regards less than one power supply as one power supply, so that the number of power supply calculations calculated by the cabinet management controller 140 is It is 3 sets.

In another embodiment, assuming that the total power consumption value is 1600 W and the maximum power supply value of the single power supply is 500 W, the cabinet management controller 140 compares the total power consumption value with the maximum power supply value of the single power supply. The calculation is performed to calculate 1600 W/500 W=3.2, that is, the number of power supply openings is 3.2, and the number of power supply calculations calculated by the cabinet management controller 140 is four.

The control unit 150 is coupled to the cabinet management controller 140, the main power supplies 110_1~110_N and the backup power supplies 120_1~120_N for receiving the power supply open quantity, and generating a plurality of control signals to start at least one main pair. Power supply and backup power supply. In this embodiment, the control unit 150 is, for example, a Complex Programming Logic Device (CPLD).

For example, the rack management controller 140 calculates the number of power supply open For example, the control unit 150 generates corresponding control signals to the main power supplies 110_1 110 110_3 and the backup power supplies 120_1 120 120_3 to activate the main power supplies 110_1 110 110_3 and the backup power supplies 120_1 120 120_3.

That is, the control unit 150 controls the number of startups of the power supply to be paired. For example, when the cabinet management controller 140 calculates that the number of power supply openings is one, the control unit 150 correspondingly activates the primary power supply 110_1 and the backup power supply 120_1. When the cabinet management controller 140 calculates that the number of power supply openers is two, the control unit 150 correspondingly activates the primary power supplies 110_1~110_2 and the backup power supplies 120_1~120_2. The rest is analogous.

Further, the foregoing control signal includes, for example, an activation signal DC_ON and a power supply signal DC_Rapidon. The start signal DC_ON is used to control whether the power supply is started. For example, when the startup signal DC_ON is at a low logic level, the operation of the power supply is turned on. When the start signal DC_ON is at a high logic level, the power supply is turned off.

The power supply signal DC_Rapidon is used to control whether the power supply is powered. For example, when the power supply signal DC_Rapidon is at a high logic level, the power supply is supplied with a high voltage, for example, 12.2V, so that the nodes 130_1~130_M operate with a power supply that provides a high voltage.

When the power supply signal DC_Rapidon is at a low logic level, the power supply is supplied with a low voltage, for example, 11.9V, so that the nodes 130_1~130_M do not operate using a power supply that provides a low voltage.

For example, when the cabinet management controller 140 calculates the number of power supply open When the quantity is one, the control unit 150 correspondingly generates the low logic level enable signal DC_ON and the high logic level power supply signal DC_Rapidon to the main power supply 110_1, and the low logic level start signal DC_ON and the low logic level. The power supply signal DC_Rapidon is supplied to the backup power supply 120_1 to activate the primary power supply 110_1 and the backup power supply 120_1, and causes the primary power supply 110_1 to supply a high voltage, and the backup power supply 120_1 provides a low voltage. Therefore, the nodes 130_1~130_M operate with the operating voltage provided by the primary power supply 110_1, and the backup power supply 120_1 serves as the backup power supply.

In addition, the control unit 150 correspondingly generates the high logic level activation signal DC_ON to the main power supply 110_2~110_N and the backup power supply 120_2~120_N to turn off the main power supply 110_2~110_N and the backup power supply 120_2~120_N. Operation. In this way, the role of power saving can be achieved.

In another embodiment, when the cabinet management controller 140 calculates that the power supply is turned on by two, the control unit 150 correspondingly generates a low logic level start signal DC_ON and a high logic level power supply signal DC_Rapidon to the main The power supply 110_1~110_2, and the low logic level enable signal DC_ON and the low logic level power supply signal DC_Rapidon are supplied to the backup power supply 120_1~120_2 to activate the main power supply 110_1~110_2 and the backup power supply 120_1~ 120_2 operates and causes the main power supplies 110_1~110_2 to provide a high voltage, while the backup power supplies 120_1~120_2 provide a low voltage. Therefore, the nodes 130_1~130_M operate with the operating voltages provided by the primary power supplies 110_1~110_2, while the backup power supplies 120_1~120_2 serve as backup power supplies.

In addition, the control unit 150 correspondingly generates the high logic level activation signal DC_ON to the main power supply 110_3~110_N and the backup power supply 120_3~120_N to turn off the main power supply 110_3~110_N and the backup power supply 120_3~120_N Operation. In this way, the role of power saving can be achieved. The rest is analogous.

After the primary power supplies 110_1~110_N and the backup power supplies 120_1~120_N are activated, a power good signal is returned to indicate whether the primary power supplies 110_1~110_N and the backup power supplies 120_1~120_N are normal. Then, the power good signal can be returned to the control unit 150, for example, so that the control unit 150 can determine whether the primary power supply 110_1~110_N and the backup power supply 120_1~120_N are in a normal state.

For example, when the power good signal is at a high logic level, it indicates that the main power supplies 110_1 110 110_N and the backup power supplies 120_1 120 120_N are in a normal state. When the power good signal is at a low logic level, it indicates that the main power supplies 110_1~110_N and the backup power supplies 120_1~120_N are not in a normal state.

Assuming that the main power supply 110_1~110_3 is activated, if the control unit 150 receives the power good signal generated by the main power supply 110_2 as a low logic level, indicating that the main power supply 110_2 is abnormal or damaged, the control unit 150 will The abnormal state is reported to the rack management controller 140, and a control signal (a low logic level start signal DC_ON and a high logic level power supply signal DC_Rapidon) is generated to the main power supply 110_4 to activate the main power supply 110_4.

However, after the control unit 150 generates the control signal to the main power supply 110_4, if the control unit 150 still receives the power good signal generated by the main power supply 110_4 as a low logic level, it indicates that the main power supply 110_2 is abnormal or If the damage occurs, the control unit 150 reports the abnormal state to the rack management controller 140, and generates a control signal (a low logic level start signal DC_ON and a high logic level power supply signal DC_Rapidon) to the main power supply 110_5 to start. Main power supply 110_5. The rest is analogous.

In addition, when the control unit 150 determines that an abnormality occurs in the main power supply, the control unit 150 further determines whether the main power supply that has an abnormality is the last one of the main power supplies 110_1 110 110_N, that is, the main power supply 110_N. If it is determined that the main power supply that is abnormal is not the last main power supply 110_N, the control unit 150 generates a control signal correspondingly to start the next main power supply.

If it is determined that the main power supply that is abnormal is the last main power supply 110_N, the control unit 150 generates a high logic level power supply signal DC_Rapidon to the backup power supply 120_1, so that the backup power supply 120_1 is supplied with a low voltage. The conversion to provide a high voltage allows the cabinet 100 to still function properly.

If an abnormality occurs in the input source received by the main power supply 110_1~110_N (for example, a power failure occurs), the main power supply 110_1~110_N does not receive the input source, and correspondingly generates a power good signal with a low logic level. Therefore, when the control unit 150 determines that the power good signals generated by all the activated main power supplies 110_1~110_3 are low logic levels, it indicates that all the main power supplies are provided. If an abnormality occurs in 110_1~110_3, the control unit 150 generates, for example, a high logic level power supply signal DC_Rapidon to a corresponding number of backup power supplies 120_1~120_3, and the backup power supply 120_1~120_3 is converted to provide a high voltage by providing a low voltage. In order to provide the working power required by the nodes 130_1~130_M, the cabinet 100 can still operate normally. In this way, it can be avoided that the cabinet 100 cannot operate when an abnormality occurs in the power supply.

In addition, if the control unit 150 determines that the power good signals generated by all the activated main power supplies are not all low logic levels, reference may be made to the operation example in which the main power supply 110_2 is abnormal, so it is no longer Narration.
