Description

Technical Field

[0001] This invention relates to the field of financial technology, and in particular to an intelligent verification device for a financial data center. Background Technology

[0002] The financial industry has high requirements for the electromechanical systems in data center infrastructure, which must have excellent availability to support the stable operation of upper-layer IT systems. Typically, manual inspection, testing, verification, confirmation, and acceptance are required during the completion and acceptance of self-built data centers and when leasing data center facilities. This process is not only highly specialized but also time-consuming and labor-intensive. For example, maintenance personnel use tools such as infrared thermometers and clamp meters to individually test the temperature and current of each server rack, manually record the data, and analyze the cooling efficiency. Liquid cooling systems require external flow meters for single-point testing.

[0003] To address the issues of time-consuming, labor-intensive, inefficient, and prone to missed inspections associated with manual inspections, some manufacturers provide heat-generating cabinets with constant power (such as a 10kW fixed load) to verify the cooling baseline of the data center. However, these cabinets still cannot simulate variable load scenarios, i.e., they cannot simulate the power fluctuations of cloud computing services, which can lead to distorted temperature rise test results.

[0040] Figure 1 This is a schematic diagram of the structure of an intelligent verification device for a financial data center provided in an embodiment of the present invention, with reference to... Figure 1 In this embodiment of the invention, the intelligent verification device 10 is connected to the data center cooling system 20 of a financial data center. The intelligent verification device 10 includes a dynamic load simulation unit 11, a first temperature sensor 12, a second temperature sensor 13, a first voltage sensor 14, a first current sensor 15, and a controller 16. The first temperature sensor 12 is used to acquire the inlet temperature information of the intelligent verification device 10; the second temperature sensor 13 is used to acquire the outlet temperature information of the intelligent verification device 10; the first voltage sensor 14 is used to acquire the output voltage information of the dynamic load simulation unit 11; the first current sensor 15 is used to acquire the output current information of the dynamic load simulation unit 11. The controller 16 is communicatively connected to the dynamic load simulation unit 11, the first temperature sensor 12, the second temperature sensor 13, the first voltage sensor 14, and the first current sensor 15, respectively, and is used to control the output power change of the dynamic load simulation unit 11, acquire the inlet temperature information, the outlet temperature information, the output voltage information, and the output current information, and determine the verification result of the data center cooling system 20 based on the inlet temperature information, the outlet temperature information, the output voltage information, and the output current information.

[0041] The intelligent verification device 10 in this embodiment of the invention is shaped like a server rack and placed in a computer room. Cool air generated by the computer room cooling system 20 enters the intelligent verification device 10 through its air inlet. When the dynamic load simulation unit 11 installed inside the intelligent verification device 10 operates, it generates heat. The cool air absorbs this heat, becoming hot air, which then exits through the air outlet of the intelligent verification device 10. A first temperature sensor 12 is located at the air inlet of the intelligent verification device 10 to obtain its inlet temperature information. A first temperature sensor 12 is also located at the air outlet of the intelligent verification device 10 to obtain its outlet temperature information. A first voltage sensor 14 is electrically connected to the dynamic load simulation unit 11 to obtain its output voltage information. A first current sensor 15 is electrically connected to the dynamic load simulation unit 11 to obtain its output current information.

[0042] The controller 16 can control the output power changes of the dynamic load simulation unit 11 according to possible real-world scenarios, thereby enabling the dynamic load simulation unit 11 to simulate different load curves. Simultaneously, the controller 16 acquires the inlet and outlet temperature information of the intelligent verification device 10, as well as the output voltage and current information of the dynamic load simulation unit 11, through the first temperature sensor 12, the second temperature sensor 13, the first voltage sensor 14, and the first current sensor 15. It is understood that the cooling effect of the data center cooling system 20 affects the inlet and outlet temperature information of the intelligent verification device 10, as well as the output voltage and current information of the dynamic load simulation unit 11. Therefore, the controller 16 can determine the verification result of the data center cooling system 20, i.e., the cooling effect, based on the acquired inlet and outlet temperature information of the intelligent verification device 10 and the output voltage and current information of the dynamic load simulation unit 11.

[0043] In this embodiment of the invention, the controller 16 is configured to control the output power of the dynamic load simulation unit 11 to be variable, simulating a real scenario. Furthermore, the controller 16 is configured to determine the verification result of the computer room cooling system 20 based on the obtained inlet temperature information, outlet temperature information, output voltage information, and output current information after controlling the output power of the dynamic load simulation unit 11 to change. This is beneficial to improving the accuracy of the verification result of the computer room cooling system 20.

[0044] As one possible implementation method, refer to Figure 1The dynamic load simulation unit 11 in this embodiment of the invention includes a programmable heating wire array 111 and a harmonic generator 112; the programmable heating wire array 111 and the harmonic generator 112 are electrically connected; the controller 16 is communicatively connected to the programmable heating wire array 111 and the harmonic generator 112 respectively, and is used to control the output power of the programmable heating wire array 111 to change according to a preset change law, and control the harmonic generator 112 to input harmonics to the programmable heating wire array 111.

[0045] In one feasible implementation, the output power P1 of the programmable heating wire array 111 satisfies: 0kW ≤ P1 ≤ 30kW. The programmable heating wire array 111 has a wide output power range and broad applicability. It should be noted that this embodiment of the invention does not limit the output power range of the programmable heating wire array 111; those skilled in the art can set it according to actual conditions.

[0046] For example, the controller 16 can control the programmable heating wire array 111 to change according to a preset change pattern, such as increasing to 100% power (e.g., 30kW) at a rate of 10% / second. At the same time, the controller 16 can also control the harmonic generator 112 to inject 5th harmonics into the programmable heating wire array 111, and the total harmonic distortion rate (THD) of the harmonics is ≤15%, in order to simulate the real load characteristics of a server with harmonic interference.

[0047] After acquiring the inlet and outlet temperature information of the intelligent verification device 10 and the output voltage and current information of the dynamic load simulation unit 11 in real time, the controller 16 can first determine the actual power of the dynamic load simulation unit 11 based on the output voltage and current information of the dynamic load simulation unit 11, then determine the inlet and outlet temperature difference of the intelligent verification device 10 based on the inlet and outlet temperature information, and finally determine the verification result of the computer room cooling system 20, i.e., the cooling effect, based on the actual power and the inlet and outlet temperature difference. For example, if the inlet and outlet temperature difference Δt is greater than the preset temperature difference threshold (e.g., 15℃), the test acceptance of the computer room cooling system 20 will be recorded as failed, along with relevant data (e.g., the actual power and the inlet and outlet temperature difference). If the deviation between the actual power and the set value is outside the preset deviation range (±3%), the test acceptance of the computer room cooling system 20 will be recorded as failed, along with relevant data.

[0048] Optionally, the intelligent verification device 10 in this embodiment of the invention further includes an electrical waveform sensor, which is electrically connected to the dynamic load simulation unit 11. The electrical waveform sensor can acquire the output voltage waveform information and / or output current waveform information of the dynamic load simulation unit 11, and transmit the waveform information related to the computer room cooling system 20 to the controller 16, which stores it in the corresponding memory and calls it when needed for viewing and application.

[0049] In this embodiment of the invention, the heating wire group in the programmable heating wire array 111 can be designed as a pluggable module, supporting future expansion to higher power.

[0050] Figure 2 This is a schematic diagram of the structure of another intelligent verification device for a financial data center provided in an embodiment of the present invention, with reference to... Figure 2 In this embodiment of the invention, the intelligent verification device 10 is also connected to the power supply system 30 of the financial data center. The power supply system 30 includes a first power supply 31 and a second power supply 32. The intelligent verification device 10 is electrically connected to the first power supply 31 and the second power supply 32 respectively. The intelligent verification device 10 also includes a dual-power switching detection unit 17. The dual-power switching detection unit 17 includes an automatic transfer switch module 171 and a second voltage sensor 172. The automatic transfer switch module 171 is used to control the power supply status of the first power supply 31 and the second power supply 32 according to the status of the first power supply 31, and record the switching time information. The second voltage sensor 172 is used to obtain the input voltage information of the intelligent verification device 10. The controller 16 is communicatively connected to the automatic transfer switch module 171 and the second voltage sensor 172 respectively, and is used to obtain the switching time information and the input voltage information, and determine the verification result of the power supply system 30 of the data center according to the switching time information and the input voltage information.

[0051] In one feasible implementation, the switching time T1 of the automatic transfer switch module 171 satisfies: T1≤20ms. The automatic transfer switch (ATS) module of this embodiment supports millisecond-level switching and records the switching time and waveform distortion, and can complete the primary / backup power switching within 20ms, meeting the requirements of Tier III and above data centers in the TIA-942 standard.

[0052] In this embodiment of the invention, the intelligent verification device 10, like other server racks in the server room, is connected to dual power supplies (i.e., a first power supply 31 and a second power supply 32) to power the intelligent verification device 10. To ensure the stability of the power supply voltage of the first power supply 31 and the second power supply 32, the power supply voltage of the first power supply 31 and the second power supply 32 is also detected to ensure that the fluctuation range of the power supply voltage of the first power supply 31 and the second power supply 32 is within the allowable fluctuation range (220V±10%). It should be noted that this embodiment of the invention uses the first power supply 31 as the main power supply and the second power supply 32 as the backup power supply as an example. When the first power supply 31 is not faulty, it powers the intelligent verification device 10. The automatic transfer switch module 171 can monitor the power status and will automatically and quickly switch the first power supply 31 to the second power supply 32 when the first power supply 31 fails, and record the switching time, thereby ensuring the continuous power supply to the load (i.e., the intelligent verification device 10 in this embodiment of the invention).

[0053] In one feasible implementation, refer to Figure 2 The automatic transfer switch module 171 is electrically connected to the first power supply 31 and the second power supply 32, respectively. The second voltage sensor 172 is electrically connected between the automatic transfer switch module 171 and the dynamic load simulation unit 11. The controller 16 determines the stability of the two power supply voltages based on the input voltage information obtained from the second voltage sensor 172 and the switching time information obtained from the automatic transfer switch module 171 when switching power supplies, and thus determines the verification result of the computer room power system 30.

[0054] For example, the first power supply 31 is automatically disconnected to simulate an external main power outage. At this time, the intelligent verification device 10 is powered by the second power supply 32, and the switching time and the voltage change amplitude at the moment of switching are recorded. When the first power supply 31 is restored, the automatic transfer switch module 171 disconnects the second power supply 32 and switches back to the first power supply 31, recording the switching time and the voltage dip amplitude at the moment of switching, while simultaneously verifying the seamless switchback function. If the switching time exceeds a preset time threshold (e.g., 20ms), the test acceptance of the data center power system 30 is recorded as failed, along with related data. If the voltage change amplitude at the moment of switching exceeds a preset voltage threshold (e.g., 5% of the rated voltage), the test acceptance of the data center power system 30 is recorded as failed, along with related data. It should be noted that the aforementioned voltage change amplitude at the moment of switching can be determined by the controller 16 based on the input voltage information of the intelligent verification device 10 obtained in real time.

[0055] Figure 3 This is a schematic diagram of the structure of another intelligent verification device for a financial data center provided in an embodiment of the present invention, with reference to... Figure 3 In this embodiment of the invention, the intelligent verification device 10 is also connected to the liquid cooling system 40 of the financial data center. The intelligent verification device 10 also includes a liquid cooling verification unit 18. The liquid cooling verification unit 18 includes a liquid cooling pipeline 181, a solenoid valve 182 disposed in the liquid cooling pipeline 181, a pressure sensor 183, and a third temperature sensor 184. The solenoid valve 182 is used to control the flow rate of the coolant in the liquid cooling pipeline 181. The pressure sensor 183 is used to acquire the pressure information of the coolant in the liquid cooling pipeline 181. The third temperature sensor 184 is used to acquire the temperature information of the coolant in the liquid cooling pipeline 181. The controller 16 is communicatively connected to the solenoid valve 182, the pressure sensor 183, and the third temperature sensor 184, respectively, and is used to control the opening degree of the solenoid valve 182 according to the preset coolant flow rate, acquire the coolant pressure information and the coolant temperature information, and determine the verification result of the liquid cooling system 40 of the data center according to the coolant pressure information and the coolant temperature information.

[0056] In one feasible embodiment, the coolant temperature S1 in the liquid cooling pipeline 181 satisfies 25℃≤S1≤60℃. For example, the liquid cooling pipeline 181 in this embodiment can be made of stainless steel, which is compatible with coolants ranging from 25℃ to 60℃, offering a wide range of applicability and resistance to damage.

[0057] For example, the controller 16 can control the opening of the solenoid valve 182 according to a preset coolant flow rate (e.g., 3 L / min or a custom value), thereby ensuring that the coolant flow rate in the liquid cooling pipeline 181 reaches the preset coolant flow rate. Optionally, to achieve precise control of the coolant flow rate by the controller 16, the liquid cooling verification unit 18 in this embodiment further includes an electromagnetic flow meter. This electromagnetic flow meter is used to sense the coolant flow rate information in the liquid cooling pipeline 181 and is also communicatively connected to the controller 16. It can transmit the sensed coolant flow rate information to the controller 16, and the controller 16 can adjust the opening of the solenoid valve 182 according to the received coolant flow rate information to ensure that the coolant flow rate in the liquid cooling pipeline 181 reaches the preset coolant flow rate.

[0058] The controller 16 can first determine the pipeline pressure drop ΔP based on the coolant pressure information and the preset coolant flow rate, and determine the coolant temperature rise ΔT based on the coolant temperature information. If the pipeline pressure drop ΔP is greater than the preset pressure drop threshold (e.g., 50 kPa), the controller records that the computer room liquid cooling system 40 has failed the test and acceptance, along with related data. If the coolant temperature rise ΔT is greater than the preset temperature threshold (e.g., 15°C), the controller records that the computer room liquid cooling system 40 has failed the test and acceptance, along with related data. To improve the accuracy of the pipeline pressure drop ΔP, the controller 16 can also determine the pipeline pressure drop ΔP based on the coolant pressure information and the coolant flow rate information.

[0059] Optionally, the liquid cooling verification unit 18 in this embodiment of the invention further includes a leakage detection electrode. The leakage detection electrode can be used to detect whether the liquid cooling pipeline 181 is leaking. It is also connected to the controller 16 and can transmit the leakage result to the controller 16 when a leakage is detected. The controller 16 can control the corresponding alarm unit (such as the audible and visual alarm unit 130 described below) to work, so as to remind the staff to carry out maintenance and stop the verification of the liquid cooling system in the computer room. The verification of the liquid cooling system in the computer room will only be re-verified after it is ensured that the liquid cooling pipeline 181 is not leaking, so as to ensure the accuracy of the verification result.

[0060] Figure 4 This is a schematic diagram of the structure of another intelligent verification device for a financial data center provided in an embodiment of the present invention, with reference to... Figure 4The intelligent verification device 10 in this embodiment of the invention also includes a vibration sensor 19 and a dust particle meter 110; the vibration sensor 19 is used to acquire vibration information of the intelligent verification device 10; the dust particle meter 110 is used to acquire the air cleanliness of the environment in which the intelligent verification device 10 is located.

[0061] For example, the vibration sensor 19 can be installed at the wind turbine bearing to sense the vibration information of the wind turbine bearing. The vibration sensor 19 is also connected to the controller 16 to transmit the sensed vibration information to the controller 16. The controller 16 can use the vibration information to determine whether the wind turbine bearing is faulty.

[0062] The dust particle meter 110 is installed on the front of the intelligent verification device 10 and can sense the air cleanliness of the computer room where the intelligent verification device 10 is located. The dust particle meter 110 is also connected to the controller 16 and can transmit the sensed air cleanliness to the controller 16. The controller 16 can determine whether the air cleanliness of the computer room meets the requirements based on the air cleanliness.

[0063] Figure 5 This is a schematic diagram of the structure of another intelligent verification device for a financial data center provided in an embodiment of the present invention, with reference to... Figure 5 In this embodiment of the invention, the intelligent verification device 10 is also connected to the data center environment monitoring system 50 of the financial data center; the data center environment monitoring system 50 is used to acquire data center environment information; the intelligent verification device 10 also includes a water leakage verification detection unit 120; the water leakage verification detection unit 120 includes a water tank 121 and a water tank solenoid valve 122 disposed at the output port of the water tank 121; the water tank solenoid valve 122 is used to control the on / off state of the output port; the controller 16 is communicatively connected to the water tank solenoid valve 122 and is used to control the water tank solenoid valve 122 to conduct, acquire data center environment information, and determine the verification result of the data center environment monitoring system 50 based on the data center environment information.

[0064] For example, when the computer room environment monitoring system 50 needs to be verified, the controller 16 can control the water tank 121 to leak a small amount of water to the intelligent verification device 10 according to the preset program of controlling the solenoid valve 122 of the water tank to turn on, to verify whether the computer room environment monitoring system 50 can detect the water leakage. If it cannot, the test acceptance of the computer room environment monitoring system 50 is recorded as not passing and related data information is recorded.

[0065] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The intelligent verification device 10 also includes an audible and visual alarm unit 130; the controller 16 is communicatively connected to the audible and visual alarm unit 130 and is used to control the working status of the audible and visual alarm unit 130 according to the verification results of the computer room cooling system 20.

[0066] For example, when the computer room cooling system 20 fails the test and acceptance, the computer room power system 30 fails the test and acceptance, the computer room liquid cooling system 40 fails the test and acceptance, the vibration information of the intelligent verification device 10 indicates a fan bearing failure, the cleanliness of the environment where the intelligent verification device 10 is located does not meet the requirements, or the computer room environment monitoring system 50 fails the test and acceptance, the controller 16 will control the audible and visual alarm unit 130 to work, issue an audible and visual alarm, and switch the load at the same time to improve safety.

[0067] Optionally, the intelligent verification device 10 in this embodiment of the invention further includes an infrared thermal imager, which is used to acquire a thermal map of the intelligent verification device 10. The infrared thermal imager is also communicatively connected to the controller 16 and can transmit the acquired thermal map to the controller 16.

[0068] Optionally, the intelligent verification device 10 in this embodiment of the invention further includes a human-machine interface (HMI), which is communicatively connected to the controller 16 and can display various parameter information obtained by the controller 16 and the verification results of each computer room system.

[0069] In one feasible implementation, the test mode can be selected via a touch-enabled human-machine interface (HMI). It should be noted that there are multiple test modes in this embodiment of the invention, and it is not limited to the two shown in Table 1 below:

[0070] Table 1

[0071]

[0072] Optionally, the intelligent verification device 10 in this embodiment of the invention connects to existing data center sensors via API to reduce the redundant deployment of sensors and thus reduce costs.

[0073] Optionally, to ensure the accuracy of the verification results from the intelligent verification device 10, the status of each sensor in the intelligent verification device 10 will be checked before verifying each system. The controller 16 will send calibration commands to the temperature sensor to verify whether the reading is within a reasonable range (0-60℃). The controller 16 will send commands to sensors such as voltage, current, and electromagnetic waveform sensors to see if they respond. The controller 16 will acquire the zero-point drift (error ≤ ±0.5%FS) of the electromagnetic flowmeter installed in the liquid cooling pipeline 181 under no-load conditions. The controller 16 will control the infrared thermal imager to perform focal length calibration until the field of view of the infrared thermal imager covers more than 80% of the area inside the cabinet. If any sensor malfunctions, the HMI panel will display a red alarm and pause the process, recommending module replacement.

[0074] The intelligent verification device 10 in this embodiment of the invention also includes a communication unit (e.g., an edge computing gateway running a Linux system). Upon startup of the edge computing gateway, the intelligent verification device 10 can establish connections with the data center cooling (air conditioning), PDU (power distribution unit), and BMS system via the Modbus TCP protocol, synchronizing timestamps.
