[0003] The current PDU control method used in server labs for scenarios involving frequent server access and disconnection is as follows: when the PDU detects an abnormal situation, such as the current total power exceeding the safe total power, the current total voltage exceeding the safe total voltage, or the current total current exceeding the safe total current, all sockets in the PDU will be powered down simultaneously. This control method may cause some unnecessary sockets to be accidentally powered down, and the power outage of the electrical equipment corresponding to the accidentally powered-down sockets will cause related tests to be interrupted, resulting in low test efficiency.

Obviously, the drawings described below are only some embodiments of the present invention.

[0056] The core of this invention is to provide a PDU control method, device, system, and storage medium that selectively energizes the sockets of plugged-in electrical devices when an abnormality of the PDU is detected. This avoids accidentally energizing sockets that do not need to be energized, thereby greatly improving experimental efficiency.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Please refer to Figure 1 , Figure 1 A flowchart of a PDU control method provided in an embodiment of the present invention, the method comprising:

[0059] S1: When an abnormality is detected in the PDU, determine the target socket to be powered off from the sockets of the electrical equipment;

[0060] S2: Power off the target socket;

[0061] The number of target sockets is less than the number of sockets into which electrical equipment is inserted. PDU abnormalities include one or a combination of the following: the current total power of the PDU exceeds the safe total power, the current total voltage of the PDU exceeds the safe total voltage, and the current total current of the PDU exceeds the safe total current.

[0062] In practice, the MCU is the main body that executes the above steps. The MCU can monitor whether the PDU is abnormal in real time. When the MCU detects that the PDU is abnormal, it determines the target socket to be powered down from the sockets of the plugged-in electrical equipment. There can be one or more target sockets to be powered down, but the number of target sockets must be less than the number of sockets of the plugged-in electrical equipment. The following embodiment shows how to determine the target socket.

[0063] It should be noted that after step S2, that is, after the target jack is powered off, it can be immediately determined whether the PDU is still abnormal. If the PDU is still abnormal, steps S1 and S2 are executed again until the PDU is detected to have returned to normal.

[0064] The PDU control method provided in this embodiment determines the target socket to be powered down from the sockets of the plugged-in electrical equipment when a PDU abnormality is detected. The target socket is a portion of all the sockets of the plugged-in electrical equipment. Therefore, when a PDU abnormality is detected, the sockets of the plugged-in electrical equipment are selectively powered down, which avoids accidentally powering down some sockets that do not need to be powered down, thereby greatly improving the experimental efficiency.

[0065] Based on the above embodiments:

[0066] As a preferred embodiment, determining the target socket to be powered off from the sockets into which electrical equipment is inserted includes:

[0067] The target socket to be powered off is determined from the sockets into which the electrical equipment is inserted, based on the power-on duration of the electrical equipment and / or the power-off priority of the socket into which the electrical equipment is inserted. The power-on duration of the electrical equipment is the time period from when the electrical equipment is powered on until the PDU abnormality is detected.

[0068] In practice, the target socket can be determined solely based on the power-on duration of the electrical equipment or the power-off priority of the socket inserted into the electrical equipment. Alternatively, both can be combined as the basis for determining the target socket. The following embodiment provides a detailed explanation of combining the two as the basis for determining the target socket.

[0069] It should be noted that the power-on duration of the electrical equipment is the time period from powering on the corresponding socket to detecting a PDU anomaly. Each socket in the PDU uniquely corresponds to a power-on duration, and the target socket is determined solely based on the power-on duration of the electrical equipment. For example, all sockets with a power-on duration not exceeding a preset duration will be powered off. Of course, the preset duration must be less than the longest of all power-on durations. Similarly, each socket in the PDU also uniquely corresponds to a power-off priority. This power-off priority can be manually set when the corresponding socket is powered on. If the MCU does not receive a manually set instruction, the powered-on socket can be set as the default power-off priority. For a detailed explanation of the power-off priority, please refer to the following embodiment.

[0070] This embodiment provides a specific method for determining the target socket. The power-on duration of the electrical equipment and the power-off priority of the socket into which the electrical equipment is inserted are used as the basis for determining the target socket. This makes the determination of the target socket more accurate. Since the power-off priority can be manually set according to the actual power consumption, the determination of the target socket is more flexible and adjustable.

[0071] As a preferred embodiment, determining the target socket to be powered off from the sockets of the electrical device based on the power-on duration of the electrical device and the power-off priority of the sockets into which the electrical device is inserted includes:

[0072] Determine if the number of electrical devices whose power-on duration is no greater than the preset duration is zero;

[0073] If so, the target socket to be powered off is determined from the sockets corresponding to electrical devices with a power-on duration longer than the preset duration, based on the power-on duration of the electrical device and the power-off priority of the socket into which the electrical device is plugged.

[0074] If not, the target socket to be powered off is determined from the sockets corresponding to electrical devices whose power-on time is no greater than the preset time, based on the power-on duration of the electrical device and the power-off priority of the socket into which the electrical device is plugged.

[0075] It should be noted that this embodiment combines power-on duration and power-off priority as the basis for determining the target socket. Devices with a power-on duration not exceeding a preset duration are given priority for power-off. Only when no device with a power-on duration not exceeding the preset duration exists are devices with a power-on duration exceeding the preset duration selected as the target socket and powered off. The following embodiment illustrates how to determine the target socket among devices with a power-on duration not exceeding or exceeding the preset duration. Of course, the preset duration should be less than the maximum power-on duration.

[0076] In this embodiment, power-off is prioritized for electrical devices whose power-on time is no longer than the preset time. This ensures that some relatively stable electrical devices are protected. Relatively stable electrical devices are those whose power-on time is longer than the preset time, thus minimizing the impact on ongoing experiments.

[0077] Please refer to Figure 2 , Figure 2 The flowchart of another PDU control method provided by the embodiment of the present invention shows that the power-down priority of the socket is divided into three levels. Of course, the specific classification method of power-down priority is not limited. The flowchart only applies to electrical devices with a power-on time longer than the preset time. It should be noted that it is also applicable to electrical devices with a power-on time not longer than the preset time.

[0078] As a preferred embodiment, the power-down priority of the socket includes a first level, a second level, and up to the Nth level, with N being an integer not less than 2;

[0079] Based on the power-on duration of the electrical equipment and the power-off priority of the sockets into which the equipment is plugged, the target sockets to be powered off are determined from those corresponding to electrical equipment with a power-on duration longer than a preset duration, including:

[0080] S11: Among the sockets corresponding to electrical devices with a power-on duration longer than the preset duration, determine the number of sockets for the Nth level of inserted electrical devices, and use the number of sockets for the Nth level of inserted electrical devices as the number of sockets for the current level of inserted electrical devices.

[0081] S12: Determine if the number of plug-in electrical devices of the current test level is zero; if yes, proceed to S13; if no, proceed to S15.

[0082] S13: Determine if the current level to be tested is the first level. If yes, proceed to S16; otherwise, proceed to S14.

[0083] S14: Determine the next higher level of the current test level as the new current test level, and return to S12;

[0084] S15: Select the socket with the shortest power-on time among the sockets of the electrical equipment under test as the target socket to be powered off.

[0085] S16: End.

[0086] It should be noted that only one target socket is determined in this embodiment. This power-down control method is more precise, controlling only one socket to power down at a time, which can minimize the impact on the ongoing experiment.

[0087] As a preferred embodiment, the power-down priority of the socket includes a first level, a second level, and up to the Nth level, with N being an integer not less than 2;

[0088] Based on the power-on duration of the electrical equipment and the power-off priority of the sockets into which the equipment is plugged, the target sockets to be powered off are determined from those corresponding to electrical equipment with a power-on duration not exceeding a preset duration, including:

[0089] S11: Among the sockets corresponding to electrical devices with a power-on duration not exceeding a preset duration, determine the number of sockets for the Nth level of inserted electrical devices, and use the number of sockets for the Nth level of inserted electrical devices as the number of sockets for the current level of inserted electrical devices.

[0090] S12: Determine if the number of plug-in electrical devices of the current test level is zero; if yes, proceed to S13; if no, proceed to S15.

[0091] S13: Determine if the current level to be tested is the first level. If yes, proceed to S16; otherwise, proceed to S14.

[0092] S14: Determine the next higher level of the current test level as the new current test level, and return to S12;

[0093] S15: Select the socket with the shortest power-on time among the sockets of the electrical equipment under test as the target socket to be powered off.

[0094] S16: End.

[0095] The specific description of this embodiment is similar to the description in the above embodiment of determining the target socket to be powered off from the sockets corresponding to electrical devices with a power-on duration longer than a preset duration, and will not be repeated here.

[0096] Please refer to Figure 3 , Figure 3 This is a structural diagram of a PDU provided in an embodiment of the present invention.

[0097] As a preferred embodiment, the process for determining the power-down priority of the sockets into which electrical equipment is inserted includes:

[0098] Receive interactive signals sent by the interactive module;

[0099] The power-down priority of the socket to be set is determined based on the interaction signal;

[0100] The determined power-down priority is set as the new priority for the socket whose priority needs to be set.

[0101] In practice, the interaction module can be one, or it can be like... Figure 3Each socket in the system is assigned a corresponding set of multiple interactive modules. When there is only one interactive module, the interactive signal emitted by the module should include an identifier corresponding to the socket whose priority is to be set and a power-down priority. The specific implementation of the interactive module is not limited; it can be a touchscreen or something else entirely. Figure 3 The button in the middle.

[0102] To enable those skilled in the art to better understand this solution, Figure 3 The following explanation uses a three-level power-down priority system as an example. Because... Figure 3 The system has a three-level power-down priority setting, therefore Figure 3 The indicator lights between the sockets and buttons use tri-color LEDs to indicate different power-down priorities. Each socket has an LED that emits red, yellow, and green light, each color representing a different power-down priority. The priority is manually set using the button next to the socket. For example, pressing the button once corresponds to the first priority (red), pressing it twice to the second priority (yellow), and pressing it three times to the third priority (green). However, this is not the only possible setting; the priority can be adjusted according to specific needs.

[0103] This embodiment provides a specific implementation method for determining the power-down priority, and the implementation process is relatively simple.

[0104] In existing technologies, power-on and power-off cycles are very frequent in server laboratories. Since the current PDU does not have a function to indicate the current remaining total power, it is difficult to assess whether the current total power of the PDU will exceed the safe total power of the PDU after connecting the power device. This results in frequent PDU overpowering, which in turn affects the use of other server nodes and causes the test to be interrupted.

[0105] As a preferred embodiment, it also includes:

[0106] Determine the current total power of the PDU;

[0107] The current remaining total power of the PDU is determined based on the safe total power and the current total power;

[0108] The control display module displays the current remaining total power.

[0109] In practice, the current total power of the PDU can be determined by acquiring the current power of each socket corresponding to the plugged-in electrical device and summing the individual current power values. Alternatively, the current total power can be determined by monitoring the current and voltage on the PDU bus.

[0110] It should also be noted that the display module can display not only the current remaining total power in this embodiment, but also the current total power, current total voltage, current total current, current remaining total voltage, power-down priority of each socket, etc. It can display all parameters of PDU operation, and no special limitation is made here.

[0111] This embodiment displays the current remaining total power through a control display module, which facilitates safety assessment by users when connecting new electrical equipment, thereby greatly avoiding frequent overpowering of the PDU due to the connection of new electrical equipment.

[0112] Please refer to Figure 4 , Figure 4 This is a structural diagram of a PDU control system provided in an embodiment of the present invention. The system includes:

[0113] The target socket determination unit 1 is used to determine the target socket to be powered off from the sockets of the electrical equipment when an abnormality of PDU is detected.

[0114] Target socket power-down unit 2 is used to control the power-down of the target socket;

[0116] In a preferred embodiment, the target socket determination unit is specifically used to determine the target socket to be powered off from the sockets inserted into the electrical device based on the power-on duration of the electrical device and / or the power-off priority of the sockets inserted into the electrical device. The power-on duration of the electrical device is the time period between the power-on of the electrical device and the detection of the PDU abnormality.

[0117] In a preferred embodiment, the target jack determination subunit includes:

[0118] The judgment unit is used to determine whether the number of electrical devices whose power-on time is not greater than the preset time is zero. If so, it enters the first target socket determination subunit; if not, it enters the second target socket determination subunit.

[0119] The first target socket determination subunit is used to determine the target socket to be powered off from the sockets corresponding to the electrical equipment whose power-on duration is longer than the preset duration, based on the power-on duration of the electrical equipment and the power-off priority of the socket into which the electrical equipment is inserted.

[0120] The second target socket determination subunit is used to determine the target socket to be powered off from the sockets corresponding to the electrical equipment whose power-on time is not greater than a preset time, based on the power-on time of the electrical equipment and the power-off priority of the socket into which the electrical equipment is inserted.

[0121] As a preferred embodiment, it also includes:

[0122] A total power determination unit is used to determine the current total power of the PDU;

[0123] The remaining total power determination unit is used to determine the current remaining total power of the PDU based on the safe total power and the current total power;
