The inventor finds out in the process of implementing the invention that: when a main power supply unit (set as PSU1) and a slave power supply unit (set as PSU2) supply power to an electronic device such as a server, the PUS2 is in a Smart standby (i.e. a mode of supporting power supply to the electronic device at any time) by default, and as the power supply of the PSU2 is realized by the power supply output of a power supply module of the PSU2, and the output end of the power supply module of the PSU2 is provided with a capacitor to realize a power-down maintaining function; if the PSU2 is subjected to hot plug operation at this time, the output of the PSU1 is shorted with the output of the PSU2 (the PSU1 charges a capacitor), so that the voltage output by the PSU1 is pulled down, and when the operating voltage of the electronic device is pulled down, the electronic device is shut down, restarted or blue-screened;
the inventors have also found in the course of carrying out the present invention that, as shown in fig. 1, in step 101, if the electronic device supports detecting the first signal; in step 102, the state of the power connection between the second power supply unit, i.e., PSU2, and the power supply port of the electronic device is analyzed by using the detected first signal, and when a hot plug operation to PSU2 is performed, the state of the power supply connection between the second power supply unit and the power supply port of the electronic device is analyzed by using step 103 based on the first signal, and a change in the state of the power supply connection between PSU2 and the power supply port of the electronic device is detected, so that in step 104, the state of the power output from the second power supply unit is controlled based on the obtained analysis result, the state of the power output from the second power supply unit can be controlled in time, the voltage output from PSU1 is stabilized, and the operation of the electronic device is ensured to be stable.
The invention is described in further detail below with reference to the figures and specific examples.

in this embodiment, the first power supply unit is configured to be a master power supply unit of the electronic device, and the second power supply unit is configured to be a slave power supply unit of the electronic device, where the first power supply unit provides electric energy to the electronic device through a power supply port (disposed on a motherboard) of the electronic device, for example, the first power supply unit may convert 220v ac power into 12v dc power to be provided to the motherboard, and may also convert 220v ac power into 5v dc power to be provided to the power supply port of a CPU according to an operating voltage (set to 5v) of another device (e.g., a CPU) on the motherboard; the second power supply unit is in an intelligent standby mode (namely, a mode for supporting power supply to the electronic equipment at any time) by default, and when the first power supply unit breaks down, the second power supply unit can ensure that the electronic equipment is continuously supplied with electric energy;
it should be noted that, before the first power supply unit fails, the second power supply unit may provide the electric energy to the power supply port together with the first power supply unit, or may provide the electric energy to the power supply port separately by the first power supply unit, depending on the load conditions of the first power supply unit and the second power supply unit; when the first power supply unit fails, the second power supply unit supplies power to the power supply port independently, that is, the second power supply unit needs to have a power supply load capacity for supplying power to the power supply port independently.
As shown in fig. 2a, the information processing method according to the present embodiment includes the steps of:
As an example, as shown in fig. 2b, the first signal may be a voltage signal of a first terminal, and the first terminal is connected to a first power source (e.g. a 3.3v power source) through a first resistor at a motherboard terminal of the electronic device; as another example, if 2c shows, the first signal may be a voltage signal of a second terminal, which is grounded through a second resistor at the output terminal of the first power supply unit; in this way, the first signal and the voltage output by the second power supply unit can keep changing synchronously, so that the output state of the second power supply unit can be represented.
In practical applications, as shown in fig. 2d, a switch unit, such as a Metal-Oxide-Semiconductor Field-effect transistor (MOSFET), may be disposed between the second power supply unit and the power supply port of the electronic device, and the switch unit is controlled to be in a cut-off state with respect to the second power supply unit, so as to achieve the effect of cutting off the second power supply unit.
In practical applications, as shown in fig. 2d, a switch unit, such as a Metal-Oxide-Semiconductor Field-effect transistor (MOSFET), may be disposed between the second power supply unit and the power supply port of the electronic device, and the switch unit is controlled to be in a conducting state with respect to the second power supply unit, so as to achieve an effect of conducting the second power supply unit; the second power supply unit is conducted by the control switch unit, so that the effect of conducting the second power supply unit is achieved.
The following describes steps 203 to 207:
referring to fig. 2b, when the power supply connection between the second power supply unit and the power supply port of the electronic device is connected, the first terminal exhibits the first level, and when the second power supply unit is pulled out (performs hot pull operation), that is, the power supply connection between the second power supply unit and the power supply port of the electronic device is disconnected, the first terminal is triggered to exhibit the second level, and the first level is higher than the second level, and a schematic diagram of turning the first level to the second level is shown in fig. 2 e;
referring to fig. 2c, when the power supply connection between the second power supply unit and the power supply port of the electronic device is connected, the first terminal exhibits the first level, and when the second power supply unit is pulled out (performs hot pull-out operation), that is, the power supply connection between the second power supply unit and the power supply port of the electronic device is disconnected, the first terminal is triggered to exhibit the second level, and the first level is higher than the second level, and a schematic diagram of turning the first level to the second level is shown in fig. 2 e.
To further illustrate the beneficial effects of the present embodiment, the inventor detects the voltages at the output terminals of the first power supply unit and the second power supply unit when the hot plug operation is performed on the second power supply unit in the related art; the voltages output by the first power supply unit and the second power supply unit in the embodiment are detected;
in the related art, the schematic diagram of the voltage output by the first power supply unit is shown in fig. 2f, the schematic diagram of the voltage input by the second power supply unit is shown in fig. 2g, when the hot-plug operation is not performed on the second power supply unit before the time T2 as shown in fig. 2f, the voltage output by the first power supply unit to the power supply port of the electronic device is kept stable (12v), when the hot-plug operation is performed on the second power supply unit at the time T1 as shown in fig. 2g, and the power-down holding capacitor is provided in the second power supply unit, and since the capacitor is discharged, the voltage applied to the power supply port of the electronic device at the side of the second power supply unit decreases from 12v from the time T1 until the time T2, the hot-plug operation is performed on the second power supply unit, and the voltage applied to the power supply port of the electronic device at the side starts to increase to 12v (since the capacitor needs to, so the voltage does not reach 12v immediately); referring to fig. 2f again, at time T2, due to the hot plug operation performed on the second power supply unit, the first power supply unit and the second power supply unit are shorted, so that the first power supply unit charges the capacitor, and the voltage (lower than 12v) applied to the power supply port of the electronic device by the first power supply unit is reduced, which results in unstable operation of the electronic device, and problems such as restart and blue screen occur;
in the embodiment, a schematic diagram of the voltage output by the first power supply unit is shown in fig. 2h, a schematic diagram of the voltage input by the second power supply unit is shown in fig. 2i, when the hot-plug operation is not performed on the second power supply unit before the time T2 as shown in fig. 2h, the voltage output by the first power supply unit to the power supply port of the electronic device is kept stable (12v), and when the hot-plug operation is performed on the second power supply unit at the time T1 as shown in fig. 2i, the power-down holding capacitor is arranged in the second power supply unit, and the voltage applied to the power supply port of the electronic device by the second power supply unit decreases from 12v from the time T1 because the capacitor discharges; at this time, with the technical solution of this embodiment, it can be determined that the power supply connection between the second power supply unit and the power supply port of the electronic device is in the disconnected state through analyzing the first signal, so as to control the switch unit to present the off state to the second power supply unit, so that, when the hot plug operation is performed on the second power supply unit at time T2, the second power supply unit is reset, and after the reset is completed, the power down holding capacitor is charged by the second power supply unit, so that the voltage applied to the power supply port of the electronic device at the second power supply unit side starts to rise (up to 12v), it should be noted that, since the second power supply unit starts the reset operation at time T2, the second power supply unit cannot start charging the capacitor immediately at time T2, and therefore, as shown in fig. 2i, the voltage (level such as the power down holding capacitor) applied to the power supply port of the electronic device by the second power supply unit is delayed for a while after time T2 Start rising (up to 12 v); when the hot plug operation is performed on the second power supply unit at the time of T2, the switch unit is in a cut-off state to the second power supply unit, so that the output of the first power supply unit is not in short circuit with the output of the second power supply unit, the condition that the first power supply unit charges the power-down holding capacitor is avoided, the voltage applied to the power supply port of the electronic equipment by the first power supply unit side is stabilized, and the stability of the working voltage of the electronic equipment is ensured.

it should be noted that before the first power supply unit 31 fails, the second power supply unit 32 may provide power to the power supply port together with the first power supply unit 31, or may provide power to the power supply port by the first power supply unit 31 alone, depending on the load conditions of the first power supply unit 31 and the second power supply unit 32; when the first power supply unit 31 fails, the second power supply unit 32 alone supplies power to the power supply port, that is, the second power supply unit 32 needs to have a power supply load capability of supplying power to the power supply port alone.

Referring to fig. 3c, when the power supply connection between the second power supply unit 32 and the power supply port of the electronic device is connected, the second terminal assumes a first level, and accordingly, the second determination unit 342 determines that the first signal maintains the first level, and determines that the power supply connection between the second power supply unit 32 and the power supply port of the electronic device is in a connected state;
when the second power supply unit 32 is unplugged (performs a hot unplugging operation), that is, the power supply connection between the second power supply unit 32 and the power supply port of the electronic device is disconnected, triggering the second terminal to present a second level, wherein the first level is higher than the second level; accordingly, when the first determination unit 341 determines that the first signal is inverted from the first level to the second level, it determines that the power supply connection between the second power supply unit 32 and the power supply port of the electronic device is in the disconnected state; the schematic diagram of the first level flipping to the second level is shown in fig. 3 e. .

In practical applications, the first power supply unit and the second power supply unit may adopt a Power Supply Unit (PSU) provided in the related art, and the detection unit 33 and the control unit 34 may be implemented by a logic programmable gate array (FPGA) of the electronic device.
To further illustrate the beneficial effects of the present embodiment, the inventor detects the voltages at the output terminals of the first power supply unit and the second power supply unit when the hot plug operation is performed on the second power supply unit in the related art; and detects the voltages output by the first power supply unit 31 and the second power supply unit 32 in the present embodiment;
in the related art, the schematic diagram of the voltage output by the first power supply unit is shown in fig. 3g, the schematic diagram of the voltage input by the second power supply unit is shown in fig. 3h, when the hot-plug operation is not performed on the second power supply unit before the time T2 as shown in fig. 3g, the voltage output by the first power supply unit to the power supply port of the electronic device is kept stable (12v), the hot-plug operation is performed on the second power supply unit 32 at the time T1 as shown in fig. 3i, the power-down holding capacitor is provided in the second power supply unit 32, and since the capacitor is discharged, the voltage applied to the power supply port of the electronic device on the side of the second power supply unit decreases from 12v from the time T1 until the hot-plug operation is performed on the second power supply unit at the time T2, the voltage applied to the power supply port of the electronic device on the side starts to increase to 12v (since the capacitor needs to be charged, so the voltage does not reach 12v immediately); with reference to fig. 3g, at time T2, due to the hot plug operation performed on the second power supply unit, the first power supply unit and the second power supply unit are shorted, so that the first power supply unit charges the capacitor, and the voltage (lower than 12v) applied to the power supply port of the electronic device by the first power supply unit is reduced, which results in unstable operation of the electronic device, and problems such as restart and blue screen occur;
in the present embodiment, a schematic diagram of the voltage output by the first power supply unit 31 is shown in fig. 3i, and a schematic diagram of the voltage input by the second power supply unit 32 is shown in fig. 3 j; as shown in fig. 3i, before time T2, the hot plug operation is not performed on the second power supply unit 32, the voltage output from the first power supply unit 31 to the power supply port of the electronic device remains stable (12v), as shown in fig. 3j, the hot plug operation is performed on the second power supply unit 32 at time T1, as shown in fig. 3k, a power down holding capacitor is provided on the second power supply unit 32 side, and since the power down holding capacitor is discharged, the voltage applied to the power supply port of the electronic device on the second power supply unit 32 side decreases from time T1 from 12 v; at this time, with the solution of this embodiment, it can be determined that the power supply connection between the second power supply unit 32 and the power supply port of the electronic device is in the disconnected state through the analysis of the first signal, so as to control the switch unit to present the off state to the second power supply unit 32, so that, when the hot plug operation is performed on the second power supply unit 32 at time T2, the second power supply unit 32 is reset, and after the reset is completed, the power-down holding capacitor is charged by the second power supply unit 32, so that the voltage applied to the power supply port of the electronic device on the side of the second power supply unit 32 starts to rise (up to 12v), it should be noted that, because the reset operation is started by the second power supply unit 32 at time T2, the second power supply unit 32 cannot immediately charge the capacitor at time T2, and therefore, as shown in fig. 3j, the voltage (level equal to the power-down holding capacitor) applied to the power supply port of the electronic device by the second power supply unit 32 at time T2 After that, the rising is started after a certain time delay (until 12 v); when the hot plug operation is performed on the second power supply unit 32 at time T2, the switch unit turns off the second power supply unit 32, so that the output of the first power supply unit 31 is not short-circuited with the output of the second power supply unit 32, the condition that the first power supply unit 31 charges the power-down holding capacitor is avoided, the voltage applied to the power supply port of the electronic device at the side of the first power supply unit 31 is stabilized, and the stability of the operating voltage of the electronic device is ensured.
