[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] refer to Figure 1 As shown, this embodiment provides a computing server power management device, including: a human-computer interaction module, a microprocessor module 3, a clock chip 4, a battery charging circuit, a battery power supply circuit, a battery pack 11, a rectifier 7, an inverter 8, a power adapter 9, and a current monitoring module 13.

The detection terminal of current monitoring module 13 is electrically connected to the output terminal of power adapter 9, and the control terminal of current monitoring module 13 is electrically connected to the second signal terminal of battery power supply circuit.

[0018] It should be noted that the computing server power management device provided in this embodiment is essentially to realize the switching of power supply mode and monitoring of power supply current of the computing server. It does not involve corresponding program improvement or algorithm improvement. The logical functions of each module can be implemented with reference to the circuit logic of existing modules.

[0019] Specifically, this embodiment designs a novel structure for the power management device of the computing server. By having the user input corresponding control commands in the human-computer interaction module, the microprocessor module 3, based on these commands and the clock signal provided by the clock chip 4, controls the battery charging circuit to charge the battery pack 11 during off-peak hours and controls the battery power supply circuit to release the battery power during peak hours. Simultaneously, the current monitoring module 13 detects the power consumption current of the computing server. When the computing server is under high load, i.e., when the current is too high, the power supply circuit of the battery pack 11 is automatically disconnected to protect the battery. This achieves overall switching of the power supply mode for the computing server, improving the power supply safety of the computing server.

[0020] Furthermore, such as Figure 1 As shown, the battery charging circuit of this embodiment includes a first static switch 5 and a first anti-reverse charging diode 6. The signal terminal of the first static switch 5 is electrically connected to the control terminal of the microprocessor module 3, the input terminal of the first static switch 5 is electrically connected to the output terminal of the rectifier 7, the output terminal of the first static switch 5 is electrically connected to the anode of the first anti-reverse charging diode 6, and the cathode of the first anti-reverse charging diode 6 is electrically connected to the input terminal of the battery pack 11.

[0021] Furthermore, such as Figure 1 As shown, the battery power supply circuit of this embodiment includes a second static switch 14, a third static switch 15, and a second anti-reverse charging diode 10; wherein, the signal terminal of the third static switch 15 is the first signal terminal, the first signal terminal is electrically connected to the control terminal of the microprocessor module 3, the input terminal of the third static switch 15 is electrically connected to the output terminal of the battery pack 11, and the output terminal of the third static switch 15 is electrically connected to the input terminal of the second static switch 14. The signal terminal of the second static switch 14 is the second signal terminal, which is electrically connected to the control terminal of the current monitoring module 13. The output terminal of the second static switch 14 is electrically connected to the anode of the second anti-reverse charging diode 10, and the cathode of the second anti-reverse charging diode 10 is electrically connected to the input terminal of the inverter 8.

[0022] Furthermore, such as Figure 1 As shown, the human-computer interaction module in this embodiment includes a display module 1 and a matrix button 2, which are electrically connected to the signal terminals of the microprocessor.

[0023] Furthermore, such as Figure 1 As shown, the device in this embodiment also includes a wireless information module 12, which is electrically connected to the signal terminal of the microprocessor module 3. The wireless information module 12 allows the microprocessor module 3 to easily obtain external power consumption information or user-input wireless control signals.

[0024] Based on the above-mentioned device circuit structure, users can input peak and off-peak electricity usage information of their area into the microprocessor module 3 through the display module 1 and matrix keypad 2; they can also access the Internet through the wireless information module 12 to obtain peak and off-peak usage information; the clock chip 4 inputs the current time to the microprocessor module 3.

[0025] If the current period is during a low-peak electricity consumption period, the microprocessor module 3 controls the first static switch 5 to turn on, and simultaneously controls the mains power supply to charge the battery pack 11 through the rectifier 7, the first static switch 5, and the first reverse charging protection diode 6. The battery pack 11 stores the electrical energy during the low-peak electricity consumption period. At the same time, the mains power supply supplies power to the inverter 8 through the rectifier 7, and the inverter 8 then supplies power to the computing server through the server's power adapter 9.

[0026] If the current period is during peak electricity consumption, the microprocessor module 3 controls the first static switch 5 to open and simultaneously controls the third static switch 15 to open. When the server current detected by the current monitoring module 13 is low, it controls the second static switch 14 to open, at which point the battery pack 11 supplies power to the inverter 8. Simultaneously, the mains power supply supplies power to the inverter 8 through the rectifier 7, and the inverter 8 then supplies power to the computing server through the server power adapter 9. At this time, both the mains power supply and the battery pack 11 supply power to the server. The battery pack 11 releases the energy stored during off-peak hours, thus achieving energy storage during off-peak hours and releasing the stored energy during peak hours to supply power to the computing server, alleviating the pressure on the power grid during peak hours and effectively reducing electricity costs.

[0027] When the current monitoring module 13 detects that the server current is too high, it controls the second static switch 14 to open, disconnecting the power supply circuit of the battery to prevent the battery from being damaged due to excessive current output, thereby improving the safety of power supply.

[0028] Based on the circuit structure of the computing server power management device in the above embodiments, in practical applications, such as Figure 2 , Figure 3 and Figure 4 As shown, the microprocessor module 3 in this embodiment uses the existing AC620 Altera FPGA development board. The development board has GPIO0~GPIO16 pins, UART_RX pin, UART_TX pin, and I... 2 C_SDA pin and I 2 The C_SCL pin serves as the signal terminal of the module, while GPIO20 and GPIO21 pins serve as the control terminals. Display module 1 uses an LCD1602 character liquid crystal display module. Its 8-bit parallel data bus pins DB0 to DB7 are electrically connected to the corresponding GPIO0 to GPIO7 pins of microprocessor module 3. The register select pin RS is electrically connected to GPIO8, the read / write select pin R / W is electrically connected to GPIO9, and the enable pin E is electrically connected to GPIO10. The VSS pin of the LCD1602 is connected to the common ground GND. These pin connections constitute the display driver circuit.

[0029] The matrix keypad 2 is an 8-bit matrix keypad (4 rows × 2 columns). Its four row scan lines ROW1 to ROW4 are electrically connected to GPIO11 to GPIO14 of the microprocessor module 3, and its two column scan lines COL1 to COL2 are electrically connected to GPIO15 to GPIO16, forming a matrix keypad scanning input circuit, which serves as a hardware interface circuit for manually inputting peak and valley time parameters.

[0030] Clock chip 4 uses a DS3231 high-precision RTC chip. Its I²C serial clock pin SCL is electrically connected to the I²C_SCL pin of microprocessor module 3, and its serial data pin SDA is electrically connected to the I²C_SDA pin of microprocessor module 3, forming a real-time clock signal input circuit.

The GND pin is connected to the common ground, forming a wireless peak and valley time information acquisition circuit.

[0032] The AC power supply is electrically connected to the AC input terminals AC1 and AC2 of the rectifier 7. The rectifier 7 uses a KBPC1010 silicon bridge rectifier, and its DC positive output terminal DC+ is divided into two outputs. The first output is connected to the power input terminal IN of the first static switch 5, the power output terminal OUT of the first static switch 5 is connected to the anode of the first reverse charging diode 6, the cathode of the first reverse charging diode 6 is connected to the positive terminal (+) of the battery pack 11, and the negative terminal (-) of the battery pack 11 is grounded. This first circuit constitutes the battery charging circuit.

[0033] The second path is directly connected to the positive DC input terminal DC_IN+ of inverter 8, forming a direct AC power supply circuit.

[0034] The first static switch 5 is a DC-SSR solid-state relay. Its control input terminal CTRL+ is electrically connected to the first I / O control pin GPIO20 of the microprocessor module 3 via a 1kΩ current-limiting resistor, while the control input terminal CTRL- is connected to common ground. When GPIO20 outputs a high level (3.3V), the power terminal of the first static switch 5 is turned on, and the battery charging circuit is connected; when GPIO20 outputs a low level, the power terminal is turned off, and the battery charging circuit is disconnected.

[0035] The first anti-reverse charging diode 6 uses a 1N4007 silicon rectifier diode to ensure that the current can only flow unidirectionally from the rectifier 7 into the battery pack 11, preventing the current of the battery pack 11 from flowing back into the first static switch 5.

[0036] The battery pack 11 uses a GFM-100 valve-regulated sealed lead-acid battery pack. Its positive terminal (+) is simultaneously connected to the power input terminal IN of the third static switch 15. The power output terminal OUT of the third static switch 15 is connected to the power input terminal IN of the second static switch 14. The power output terminal OUT of the second static switch 14 is connected to the anode of the second reverse charging diode 10. The cathode of the second reverse charging diode 10 is connected to the DC positive input terminal DC_IN+ of the inverter 8, thus forming a battery discharge power supply circuit.

[0037] Among them, the third static switch 15 adopts a DC-SSR DC solid-state relay. Its control input terminal CTRL+ is electrically connected to GPIO21 of microprocessor module 3 through a 1kΩ current-limiting resistor, and CTRL- is connected to the common ground.

[0038] The second static switch 14 is a DC-SSR solid-state relay. Its control input terminal CTRL+ is electrically connected to the output terminal OUT of the current monitoring module 13 through a 1kΩ current-limiting resistor, and the CTRL- pin is connected to the common ground.

[0039] Inverter 8 uses a BELTTT3000 pure sine wave inverter. Its DC positive input terminal DC_IN+ simultaneously receives DC+ mains DC power from rectifier 7 and DC discharge power from the battery discharge source at the cathode of the second anti-reverse charging diode 10. Its DC negative input terminal DC_IN- is connected to common ground. The AC output terminals AC_OUT_L and AC_OUT_N of inverter 8 are electrically connected to the AC input terminals AC_IN_L and AC_IN_N of the server's power adapter 9.

[0040] The server's power adapter 9 uses an Avalon Nano 3 140W power adapter, whose DC output terminals DC_OUT+ and DC_OUT- provide operating power to the computing server.

[0041] The second anti-reverse charging diode 10 uses a 1N4007 silicon rectifier diode to ensure that the current can only flow from the battery pack 11 into the inverter 8 in one direction, preventing the current at the input terminal of the inverter 8 from flowing back into the discharge circuit of the battery pack 11.

[0042] Connect a 0.01Ω sampling resistor in series to the DC_OUT+ positive output cable of the server power adapter 9 and connect it to the input terminal SENSE of the current monitoring module 13 (i.e., the RSL-13 integrated overcurrent protector). Connect the GND pin to the common ground.

[0043] The protection signal output terminal OUT of the current monitoring module 13 (RSL-13) is electrically connected to the CTRL+ pin of the second static switch 14 via a 1kΩ current limiting resistor, forming an independent hardware protection signal path that does not pass through any pin of the microprocessor module 3.

[0044] Users can input the peak and off-peak electricity usage times of their area into the FPGA chip of the microprocessor module 3 through the display module 1 (LCD1602) and the matrix keypad 2; they can also access the Internet to obtain peak and off-peak usage information through the Boudica120 NB-IoT chip of the wireless information module 12.

[0045] Clock chip 4 (DS3231) transmits the current real-time time information to the I²C_SCL and I²C_SDA pins of microprocessor module 3 via its SCL and SDA pins. If the current time is during a low electricity consumption period, the GPIO20 pin of microprocessor module 3 outputs a high level, which drives the CTRL+ of the first static switch 5 (DC-SSR) through the 1kΩ current-limiting resistor R3, turning on the first static switch 5 and connecting the battery charging circuit; at the same time, the GPIO21 pin outputs a low level, turning off the third static switch 15 and disconnecting the battery discharging circuit. At this time, the mains power charges the positive terminal + of battery pack 11 (GFM-100) through rectifier 7 (KBPC1010), the first static switch 5, and the first reverse charging diode 6 (1N4007); on the other hand, it supplies power to the computing server through rectifier 7, inverter 8 (BELTTT3000), and server power adapter 9 (Avalon Nano 3 140W).

[0046] If the current time is during peak electricity consumption, microprocessor module 3 outputs a low level through GPIO20, turning off the first static switch 5 and stopping battery charging; simultaneously, it outputs a high level through GPIO21 to drive the third static switch 15 to conduct, and when the current monitoring module 13 detects that the server current does not exceed 35A, it outputs a high level through OUT, turning on the second static switch 14. At this time, the battery pack 11 (GFM-100) releases the stored electrical energy, which is transmitted to the DC_IN+ terminal of inverter 8 (BELTTT3000) through its positive terminal (+), the third static switch 15, the second static switch 14, and the second anti-reverse charging diode 10. This energy is then combined with the DC power supplied by the mains power through rectifier 7 at the input of inverter 8, forming a circuit mode in which the mains power and the battery are connected in parallel.

[0047] When the computing server consumes more than 35A of current, the OUT pin of the current monitoring module 13 outputs a low level, causing the second static switch 14 to turn off. The discharge circuit of the battery pack 11 is then hardware-disconnected, protecting the battery pack 11.

[0048] In the description of the embodiments of this utility model, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
