[0002] Computer equipment in data center server rooms is typically powered by two power supplies. With the rapid development of the data center industry, the security of data center power supply and distribution systems is of paramount importance.

[0003] Due to misoperation by data center construction personnel and equipment installation personnel, some computer equipment may appear to be powered by two power lines, and each power distribution unit may be functioning normally, but in reality, they are connected to the same power supply. In this situation, if the power supply fails, it will disrupt the normal operation of the data center.

[0004] Currently, the power supply type of each power distribution unit in the power supply and distribution system can be determined by manually checking the power distribution line information one by one.

[0020] When both the fixed power line carrier module and the mobile power line carrier module are connected to the third power distribution unit, the mobile power line carrier module sends second verification information to the fixed power line carrier module.

[0021] Specifically, when the first verification information is successfully displayed on the mobile power line carrier module and the second verification information is successfully displayed on the fixed power line carrier module, both the fixed power line carrier module and the mobile power line carrier module are in a non-fault state.

[0029] As can be seen from the above technical solution, this application has the following beneficial effects:

[0036] Figure 5 This is a schematic diagram of a power supply and distribution testing device provided in an embodiment of this application. Detailed Implementation

[0037] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] To facilitate understanding and explanation of the technical solutions provided in the embodiments of this application, the background technology involved in the embodiments of this application will be introduced first.

[0039] With the rapid development of the data center industry, the security of data center power supply and distribution systems is of paramount importance. Most data center failures and system outages are caused by the power supply and distribution system.

[0040] Computer equipment in data center server rooms is typically powered by two power supplies, A and B. However, due to misoperation by server room construction personnel and equipment installation personnel, some computer equipment may appear to be powered by two power lines, and all power distribution units may be functioning normally, but in reality, they are connected to the same power supply. This phenomenon is commonly known as "false dual-circuit." In this case, if the power supply fails, it will cause losses to the normal operation of the data center.

[0041] Currently, offline verification can be performed by shutting down the equipment, specifically for pre-delivery commissioning of the data center. For example, power distribution unit A can be de-energized, and it can be recorded whether all dummy loads in the data center are powered by power distribution unit B. If any dummy load is found to have dual-power indicator lights on or no power, it indicates a false dual-power situation, requiring construction personnel to check the power supply and distribution line information. If the data center is already in operation, the computer equipment needs to be switched to standby, and offline and shutdown preparations should be made. In actual data center operation and maintenance cases, computer equipment often cannot be switched due to the sensitivity of applications. Based on this, manual inspection of the power distribution system's distribution line information can be used to determine the power supply type of each power distribution unit in the power supply and distribution system. However, manual inspection is neither accurate nor efficient, and it is prone to safety accidents.

[0042] Based on this, this application provides a power supply and distribution inspection system, which includes a fixed power line carrier module and a mobile power line carrier module. The fixed power line carrier module is connected to a first power distribution unit, and the mobile power line carrier module is connected to a second power distribution unit. The fixed power line carrier module continuously sends power supply and distribution inspection information to the mobile power line carrier module. The power supply for the first power distribution unit has been determined to be the first power source. If the power supply and distribution inspection information is not displayed successfully on the mobile power line carrier module, the power supply for the second power distribution unit is the second power source. If the power supply and distribution inspection information is displayed successfully on the mobile power line carrier module, the power supply for the second power distribution unit is the first power source. Thus, compared to manual inspection of power supply and distribution lines, determining the power supply type of all power distribution units in the computer room based on the fixed power line carrier module and the mobile power line carrier module improves accuracy and safety, and subsequently allows for the determination of whether a power supply and distribution problem has occurred.

[0043] To facilitate understanding of the power supply and distribution testing system provided in the embodiments of this application, some technical terms will be explained first.

[0044] Power line carrier technology is a communication method that uses power lines to transmit data and voice signals, and it is often used in pairs. Module A is responsible for modulating the data or voice signal onto the power line, and module B is responsible for demodulating the corresponding signal on the power line. Power line carrier technology has significant advantages such as no need for wiring, wide coverage, and convenient connection.

[0045] To facilitate understanding of the power supply and distribution testing system provided in the embodiments of this application, the following is combined with... Figure 1 The example scenario is shown below. See also... Figure 1 As shown in the figure, this figure is a schematic diagram of an exemplary application scenario provided in the embodiments of this application.

[0046] In practical applications, the power supply and distribution inspection system includes a fixed power line carrier module and a mobile power line carrier module. The fixed power line carrier module is connected to the first power distribution unit and is used to continuously send inspection information for power supply and distribution to the mobile power line carrier module. The power supply for the first power distribution unit has been identified as the first power source. It is understood that the fixed power line carrier module in this embodiment is module A in power line carrier technology, responsible for modulating data or voice signals onto the power line.

[0047] The mobile power line carrier module is connected to the second power distribution unit. It is understood that the mobile power line carrier module in this embodiment is module B in power line carrier technology, responsible for demodulating the corresponding signal on the power line.

[0048] In principle, the fixed power line carrier module sends power supply and distribution verification information to the mobile power line carrier module. If the verification information fails to display successfully on the mobile power line carrier module, it indicates that the mobile power line carrier module has not received the verification information, proving that the second power distribution unit and the first power distribution unit are not connected. The power supply of the second power distribution unit is different from that of the first power distribution unit; the power supply of the second power distribution unit is the second power source. If the verification information displays successfully on the mobile power line carrier module, it proves that the second power distribution unit and the first power distribution unit are connected. The power supply of the second power distribution unit is the same as that of the first power distribution unit; the power supply of the second power distribution unit is the first power source.

[0049] Those skilled in the art will understand that Figure 1 The schematic diagram shown is merely one example in which embodiments of this application can be implemented. The scope of application of the embodiments of this application is not limited by any aspect of this framework.

[0050] To facilitate understanding of this application, the following description, in conjunction with the accompanying drawings, illustrates a power supply and distribution testing system provided in an embodiment of this application.

[0051] According to the data center design standard GB50174-2017, Class A data centers should be powered by dual power supplies, and Class B data centers should preferably be powered by dual power supplies. Class A data centers are "fault-tolerant" systems with the highest reliability and availability levels. Class B systems are "redundant" systems. In data center server rooms, dual power supplies (A and B) are used so that if one power supply fails, the other can take over the power supply. If two power supplies in a rack are connected to the same circuit, and the two power supplies have the same markings, indicating they are the same circuit, this is a "false dual-circuit" situation. In this case, the power lines of the computer equipment in the rack should be rectified to prevent potential accidents.

[0052] See Figure 2 As shown, this figure is a schematic diagram of a power supply and distribution testing system provided in an embodiment of this application. Figure 2 As shown, leveraging the characteristic of power line carrier technology to transmit data and voice signals online along phase channels, the power supply and distribution testing system provided in this application includes a fixed power line carrier module and a mobile power line carrier module. Both the fixed and mobile power line carrier modules are implemented based on power line carrier technology.

[0053] like Figure 2As shown, both the fixed power line carrier module and the mobile power line carrier module include a power line plug for connection to the power distribution unit. Both modules also include a display screen, a keyboard module, a transmitting module, a receiving module, a restart module, and a switch module. In practical applications, the mobile power line carrier module can determine whether the power supply and distribution test information is displayed successfully via the display screen. The keyboard module is used to generate the power supply and distribution test information. The transmitting module is used to send the power supply and distribution test information. The receiving module is used to receive the power supply and distribution test information. The restart module is used to restart the device. The switch module is used to turn the device on or off.

[0054] Because power line carrier technology can only transmit signals over a single power supply and cannot cross isolation transformers, a fixed power line carrier module can use power line carrier technology to send power supply and distribution verification information. The ability of a mobile power line carrier module to receive this verification information can be used to verify whether the power supply to the two power distribution units of a server rack in a data center is the same. In this embodiment, the server rack is a dual-power rack, meaning it includes two power distribution units.

[0055] Specifically, in one or more embodiments, a fixed power line carrier module is connected to a first power distribution unit and is used to continuously send power supply and distribution verification information to a mobile power line carrier module. As an optional example, the power supply and distribution verification information can be custom fields, such as numbers and text. It is understood that the fixed power line carrier module in the embodiments of this application is module A in power line carrier technology, responsible for modulating data or voice signals onto power line A.

[0056] In this context, the power supply for the first power distribution unit has been identified as the first power source. In practical applications, as an optional example, the power supply for the first power distribution unit can be determined as the first power source by manually inspecting the wiring.

[0057] The mobile power line carrier module is connected to the second power distribution unit. It is understood that the mobile power line carrier module in this embodiment is module B in power line carrier technology, responsible for demodulating the corresponding signal on power line B. The second power distribution unit can be a power distribution unit located in the same cabinet as the first power distribution unit, or it can be any power distribution unit in other cabinets within the computer room.

[0058] In principle, the fixed power line carrier module sends power supply and distribution verification information to the mobile power line carrier module. If the verification information is not successfully displayed on the mobile power line carrier module, it indicates that the mobile power line carrier module has not received the verification information, proving that the second power distribution unit and the first power distribution unit are not connected. The power supply for the second power distribution unit is different from that for the first power distribution unit; the second power distribution unit is powered by the second power source.

[0059] If the power supply and distribution test information is successfully displayed on the mobile power line carrier module, it proves that the second power distribution unit and the first power distribution unit are connected. The power supply of the second power distribution unit is the same as that of the first power distribution unit, and the power supply of the second power distribution unit is the first power source.

[0060] In practical applications, after the second power distribution unit has been tested, the mobile power line carrier module is disconnected from the tested second power distribution unit, and the mobile power line carrier module is connected to the untested power distribution units in the computer room for testing, until all power distribution units in the computer room cabinets have been tested.

[0061] As one optional example, the first power supply is power supply A, and the second power supply is power supply B. As another optional example, the first power supply is power supply B, and the second power supply is power supply A.

[0062] Understandably, when the first power distribution unit and the second power distribution unit are in the same cabinet, the fixed power line carrier module is connected to the first power distribution unit, and the power supply for the first power distribution unit is the first power source. The fixed power line carrier module continuously sends power supply and distribution verification information. The mobile power line carrier module is then connected to the second power distribution unit. If the mobile power line carrier module displays the power supply and distribution verification information, then the power supply for the first power distribution unit and the second power distribution unit is the same, directly indicating that there is a wiring and power supply error in the power distribution units in this cabinet, resulting in a false dual-path configuration.

[0063] In practical applications, each power distribution unit in a server rack is labeled to indicate whether it is powered by the first or second power supply. However, there can be situations where the label on the power distribution unit does not match the actual power supply. For example, in a dual-power rack, the two power distribution units are labeled as "first power supply" and "second power supply," respectively. However, due to possible misoperation by data center construction personnel or equipment installation personnel, the two power distribution units in the dual-power rack may be falsely configured as dual-power supply units. In this case, the label on the power distribution unit and the actual power supply will not match.

[0064] Based on this, in this embodiment of the application, when using a fixed power line carrier module and a mobile power line carrier module to test power supply and distribution, if a mismatch is detected between the power supply and tag of the power distribution unit, the tag is immediately corrected on-site. After all power distribution units in all server racks in the computer room have been verified online, for each rack, if two power distribution units in a rack have the same tag, then the dual power supply in that rack is a false dual-path, posing a single point of risk. Subsequent rectification of the outage lines is necessary to prevent this risk from escalating into an accident.

[0065] It should be noted that when using fixed and mobile power line carrier modules for power supply and distribution testing, it is necessary to first ensure that both modules are fault-free; that is, they must be zeroed first. As an optional example, both the fixed and mobile power line carrier modules are connected to a third power distribution unit. The fixed power line carrier module sends a first verification message to the mobile power line carrier module, and the mobile power line carrier module sends a second verification message to the fixed power line carrier module. When the first verification message is displayed as successful on the mobile power line carrier module and the second verification message is displayed as successful on the fixed power line carrier module, the communication between the fixed and mobile power line carrier modules is normal, indicating a non-faulty state. The third power distribution unit can be any power distribution unit in the server rack of the computer room.

[0066] It is understood that the power supply and distribution testing system provided in this application embodiment can verify the power supply and distribution in the computer room in real time online, without the need to shut down the equipment in the computer room for offline re-verification, thus not delaying the use of the equipment. Moreover, compared with manual inspection and manual operation, the power supply and distribution testing system provided in this application embodiment has higher accuracy and security.

[0067] Based on the power supply and distribution inspection system provided in the above-described method embodiments, this application also provides a power supply and distribution inspection method, which will be described below with reference to the accompanying drawings. It is understood that the technical implementation details of this power supply and distribution inspection method are similar to those of the power supply and distribution inspection system provided in the above embodiments, and will not be repeated here.

[0068] See Figure 3 As shown, this figure is a flowchart of a power supply and distribution testing method provided in an embodiment of this application. This method is applied to a power supply and distribution testing system, which includes a fixed power line carrier module and a mobile power line carrier module. Figure 3 As shown, the power supply and distribution inspection method may include the following steps:

[0069] S301: When the fixed power line carrier module is connected to the first power distribution unit and the mobile power line carrier module is connected to the second power distribution unit, the fixed power line carrier module continuously sends power supply and distribution verification information to the mobile power line carrier module.

[0070] Wherein, if the power supply and distribution test information is not successfully displayed on the mobile power line carrier module, the power supply of the second power distribution unit is the second power supply; if the power supply and distribution test information is successfully displayed on the mobile power line carrier module, the power supply of the second power distribution unit is the first power supply.

[0071] In one possible implementation, the first power distribution unit and the second power distribution unit are in the same cabinet and the power supply corresponding to the first power distribution unit and the second power distribution unit is the same, and there is a power supply error between the first power distribution unit and the second power distribution unit.

[0072] In one possible implementation, the method further includes:

[0073] When both the fixed power line carrier module and the mobile power line carrier module are connected to the third power distribution unit, the fixed power line carrier module sends first verification information to the mobile power line carrier module.

[0074] When both the fixed power line carrier module and the mobile power line carrier module are connected to the third power distribution unit, the mobile power line carrier module sends second verification information to the fixed power line carrier module.

[0075] When the first verification information is successfully displayed on the mobile power line carrier module and the second verification information is successfully displayed on the fixed power line carrier module, both the fixed power line carrier module and the mobile power line carrier module are in a non-fault state.

[0076] It is understood that the power supply and distribution testing method provided in this application embodiment can verify the power supply and distribution in the computer room in real time online, without the need to shut down the equipment in the computer room for offline re-verification, thus not delaying the use of the equipment. Moreover, compared with manual inspection and manual operation, the power supply and distribution testing system provided in this application embodiment has higher accuracy and security.

[0077] See Figure 4 , Figure 4 A flowchart illustrating another power supply and distribution testing method provided in an embodiment of this application. Figure 4 As shown, the method may include steps S401-S406:

[0078] S401: When both the fixed power line carrier module and the mobile power line carrier module are connected to the third power distribution unit, the fixed power line carrier module sends the first verification information to the mobile power line carrier module.

[0079] S402: When both the fixed power line carrier module and the mobile power line carrier module are connected to the third power distribution unit, the mobile power line carrier module sends the second verification information to the fixed power line carrier module.

[0080] Understandably, the first and second verification information are used to verify whether the fixed power line carrier module and the mobile power line carrier module can communicate with each other normally.

[0081] S403: Determine if the zeroing process passed; if it passed, execute S404.

[0082] When the zeroing passes, the fixed power line carrier module and the mobile power line carrier module communicate normally with each other, and neither module is faulty. When the zeroing fails, replace the fixed power line carrier module and the mobile power line carrier module, and then re-execute S401.

[0083] S404: When the fixed power line carrier module is connected to the first power distribution unit and the mobile power line carrier module is connected to the second power distribution unit, the fixed power line carrier module continuously sends power supply and distribution verification information to the mobile power line carrier module; the power supply of the first power distribution unit is the first power supply; the first power distribution unit and the second power distribution unit belong to the same cabinet.

[0084] Once it is confirmed that both the fixed power line carrier module and the mobile power line carrier module are fault-free, the fixed power line carrier module is connected to the first power distribution unit, and the mobile power line carrier module is connected to the second power distribution unit. The first and second power distribution units are located in the same cabinet. The fixed power line carrier module continuously sends power supply and distribution verification information to the mobile power line carrier module.

[0085] When the power distribution test information is displayed in the second power distribution unit, it indicates that the power supply for both the first and second power distribution units is the same, specifically the first power supply. There is a power distribution error in the cabinets belonging to both the first and second power distribution units. Conversely, when the power distribution test information is not displayed in the second power distribution unit, it indicates that the power supply for the first and second power distribution units is different, and the second power distribution unit is powered by the second power supply. There is no power distribution error in the cabinets belonging to either the first or second power distribution units. During this process, the power supply of the second power distribution unit is checked against the label on the second power distribution unit; if they do not match, they are corrected promptly.

[0086] S405: When the fixed power line carrier module is connected to the first power distribution unit and the mobile power line carrier module is connected to the fourth power distribution unit, the fixed power line carrier module continuously sends power supply and distribution verification information to the mobile power line carrier module; the first power distribution unit and the second power distribution unit belong to different cabinets.

[0087] Disconnect the mobile power line carrier module from the second power distribution unit, and connect the mobile power line carrier module to the fourth power distribution unit. Perform the same verification process. During this process, verify the power supply of the fourth power distribution unit against the label on the fourth power distribution unit. If they do not match, make the necessary changes immediately.

[0088] When all power distribution units in the server room have been verified online, if the dual power distribution units in a server room have the same label, then the dual power supply in that server room is a "false dual power supply", which poses a single point of risk. It is necessary to promote the rectification of the power outage line to prevent the risk from turning into an accident.

[0089] Based on the power supply and distribution testing method provided in the above embodiments, this application also provides a power supply and distribution testing device, which will be described below with reference to the accompanying drawings. It is understood that the technical implementation details of this power supply and distribution testing device are similar to those of the power supply and distribution testing system provided in the above embodiments, and will not be repeated here.

[0090] See Figure 5 , Figure 5 This is a schematic diagram of a power supply and distribution testing device provided in an embodiment of this application. The device is applied to a power supply and distribution testing system, which includes a fixed power line carrier module and a mobile power line carrier module. Figure 5 As shown, the device includes:

[0091] The first transmitting unit 501 is used to continuously send power supply and distribution verification information to the mobile power line carrier module when the fixed power line carrier module is connected to the first power distribution unit and the mobile power line carrier module is connected to the second power distribution unit; the power supply of the first power distribution unit is the first power supply.

[0092] Wherein, if the power supply and distribution test information is not successfully displayed on the mobile power line carrier module, the power supply of the second power distribution unit is the second power supply; if the power supply and distribution test information is successfully displayed on the mobile power line carrier module, the power supply of the second power distribution unit is the first power supply.

[0093] In one possible implementation, the first power distribution unit and the second power distribution unit are in the same cabinet and the power supply corresponding to the first power distribution unit and the second power distribution unit is the same, and there is a power supply error between the first power distribution unit and the second power distribution unit.

[0094] In one possible implementation, the device further includes:

[0095] The second transmitting unit is used to send first verification information from the fixed power line carrier module to the mobile power line carrier module when both the fixed power line carrier module and the mobile power line carrier module are connected to the third power distribution unit.

[0096] The third transmitting unit is used to send second verification information from the mobile power line carrier module to the fixed power line carrier module when both the fixed power line carrier module and the mobile power line carrier module are connected to the third power distribution unit.

[0097] When the first verification information is successfully displayed on the mobile power line carrier module and the second verification information is successfully displayed on the fixed power line carrier module, both the fixed power line carrier module and the mobile power line carrier module are in a non-fault state.

[0098] This application provides a power supply and distribution testing device applied to a power supply and distribution testing system. The system includes a fixed power line carrier module and a mobile power line carrier module. The fixed power line carrier module is connected to a first power distribution unit, and the mobile power line carrier module is connected to a second power distribution unit. The fixed power line carrier module continuously sends power supply and distribution testing information to the mobile power line carrier module. The power supply for the first power distribution unit has been determined to be the first power source. If the power supply and distribution testing information is deemed unsuccessful on the mobile power line carrier module, the power supply for the second power distribution unit is determined to be the second power source. If the power supply and distribution testing information is deemed successful on the mobile power line carrier module, the power supply for the second power distribution unit is determined to be the first power source. Thus, compared to manual inspection of power supply and distribution lines, determining the power supply type of all power distribution units in the computer room based on the fixed and mobile power line carrier modules improves accuracy and safety, and subsequently allows for the determination of whether a power supply and distribution problem has occurred.
