[0034] Specifically, such as Figure 1 As shown, the first power module 1 is, for example, an AC-DC converter. It is connected to the input port 94 via the seventh power line 87, receiving 220V AC power. The first power module 1 converts the 220V voltage to 12V DC power. The first power module 1 then outputs this DC power to a 12V device via the sampling module 4. The first power module 1 also outputs the DC power to the second power module 2 and the third power module 3 via the eighth power line 88. The second power module 2 and the third power module 3 can both be, for example, direct current (DC-DC) converters. The second power module 2 converts the 12V DC power to 5V DC power and outputs this 5V DC power to a 5V device via the sampling module 4. The third power module 3 converts the 12V DC power to 3.3V DC power and outputs this 3.3V DC power to a 3.3V device via the sampling module 4.

[0035] The sampling module 4 is used to send the collected voltage and current of the first DC power supply, the second DC power supply, and the third DC power supply to the detection module 5, which is, for example, a voltage and current detection module.

It can also send the voltage and current data to the host computer for synchronous display, making it convenient for users to draw the voltage and current waveform of the device, thereby more accurately judging whether the test value meets the power consumption requirements and improving the user experience.

[0037] Optionally, such as Figure 1 As shown, the sampling module 4 includes a first sampling module 41, a second sampling module 42, and a third sampling module 43.

[0038] Specifically, such as Figure 1 As shown, the first sampling module 41 is used to collect the voltage and current of the 12V first DC power supply. The first sampling module 41 includes, for example, four parallel 33mΩ resistors with a rated power of 1W, the maximum detection current is, for example, 10A, and the minimum detection current is, for example, 5mA.

[0039] The second sampling module 42 is used to collect the voltage and current of the 5V second DC power supply. The second sampling module 42 may include, for example, a 33mΩ resistor with a rated power of 1W, a maximum detection current of, for example, 3A, and a minimum detection current of, for example, 10mA.

[0040] The third sampling module 43 is used to collect the voltage and current of the 3.3V third DC power supply. The third sampling module 43 may include, for example, a 50mΩ resistor with a rated power of 1W, a maximum detection current of, for example, 1.5A, and a minimum detection current of, for example, 1mA.

[0041] Therefore, by setting up the first sampling module 41, the second sampling module 42 and the third sampling module 43, the simultaneous acquisition of voltage and current from multiple channels is realized, thereby improving the acquisition efficiency of voltage and current.

[0046] Optionally, such as Figure 1 As shown, the first end of the third sampling module 43 is connected to the detection module 5 through the fifth analog input signal line 75, and the second end of the third sampling module 43 is connected to the detection module 5 through the sixth analog input signal line 76; the third end of the third sampling module 43 is connected to the third power module 3 through the fifth power line 85, and the fourth end of the third sampling module 43 is connected to the detection module 5 and the data processing and communication module 6 through the sixth power line 86 respectively.

[0048] Optionally, such as Figure 1 As shown, the data processing and communication module 6 includes a data processing module 61 and a communication module 62; both the communication module 62 and the detection module 5 are connected to the data processing module 61; the data processing module 61 is used to read and process the voltage and current of the first DC power supply, the voltage and current of the second DC power supply and the voltage and current of the third DC power supply collected by the detection module 5, and send the voltage and current of the first DC power supply, the voltage and current of the second DC power supply and the voltage and current of the third DC power supply to the host computer through the communication module 62.

[0049] For example, such as Figure 1 As shown, the data processing module 61 is connected to the detection module 5 via an I2C interface. The data processing module 61 can periodically read the voltage and current of the first DC power supply, the second DC power supply, and the third DC power supply, and process the data. The data processing module 61 sends the read voltage and current of the first DC power supply, the second DC power supply, and the third DC power supply to the communication module 62 via the RMII interface.

[0050] Optionally, such as Figure 1 As shown, the data processing module 61 is also connected to the host computer via a data interface to obtain data reading instructions sent by the host computer.

[0051] Specifically, such as Figure 1 As shown, the data processing module 61 can also receive voltage and current data reading commands from the host computer via the RMII interface, reading the voltage and current of the first DC power supply, the second DC power supply, and the third DC power supply before sending them back to the host computer. The host computer can display the data and save historical data, providing a solid foundation for subsequent analysis. With this detailed data, users can easily plot the voltage and current waveforms of the device, thereby more accurately determining whether the test values ​​meet the power consumption requirements. This not only broadens the boundaries of data application but also brings convenience to the energy efficiency management and troubleshooting of the device.

[0052] Optionally, such as Figure 1As shown, the communication module 62 includes an Ethernet chip.

[0053] Specifically, such as Figure 1 As shown, the Ethernet chip is a tiny controller that integrates the Ethernet media access controller and the physical interface transceiver into a single chip, eliminating the need for many external components.
