Description

Technical Field

[0001] The present invention relates to computer power management technology, and in particular to a method and system for reducing computer power consumption. Background Art

[0002] In the field of computer power management, maintaining a constant CPU supply voltage is a core technical challenge in reducing system power consumption. Existing CPU supply voltage regulation is usually achieved through two methods: dynamic software regulation and hardware regulation. However, the defects of these two methods are: the existing pure software dynamic voltage regulation (DVS) relies on scheduling instructions at the operating system level, and its communication delay causes the impact of the dynamic voltage replenishment mechanism to lag. Hardware voltage regulation solutions based on mechanical variable resistors or relay switching (such as reed relay voltage divider networks) can achieve improved steady-state accuracy, but due to mechanical action delays and voltage deviation from the constant target value, instantaneous power consumption surges. In addition, existing voltage regulation technologies are all single-execution, unable to coordinate the sustainability of the mechanical mode and the transient compensation capability of electronic regulation, resulting in the inability to coordinate the differentiated voltage constant requirements of transient disturbances and steady-state operation, resulting in significant voltage fluctuations and serious energy efficiency loss. Summary of the Invention

[0003] The present invention provides a system and method for reducing computer power consumption. By coordinating the continuous adjustment module with the transient adjustment module, and integrating the innovative architecture of mechanical mode continuous adjustment with electronic transient compensation, the system achieves stable and safe CPU power supply voltage. The specific solution is as follows:

[0007] The monitoring module is used to collect CPU temperature, power supply current and voltage fluctuation data in real time;

[0008] The control module is connected to the monitoring module, the continuous regulation module and the instantaneous regulation module respectively. The control module selects the instantaneous regulation module or the continuous regulation module to perform voltage regulation according to whether the fluctuation value of the monitoring data exceeds a preset threshold range.

[0009] Preferably, the continuous adjustment module includes:

[0010] The variable resistor unit includes a connecting substrate and a variable resistor portion, wherein the variable resistor portion is composed of a plurality of unit resistors with linear / nonlinear resistance distribution and a plurality of insulating plates arranged alternately; the unit resistors and insulating plates are respectively mounted on the connecting substrate;

[0011] The dynamic connection unit is slidably connected to the variable resistance part, and the voltage is adjusted by contacting unit resistors of different resistance values;

[0012] A driving unit is located on the side of the variable resistance portion where the resistance value is the smallest, and the driving unit is driven by the control module;

[0013] The protection unit is located on the side of the variable resistor with the largest resistance. When the output voltage of the power supply exceeds the safety value, it is detachably connected to the dynamic connection unit to cut off the power supply to the CPU.

[0015] Preferably, the driving unit includes: a pushing electromagnet and a reset unit;

[0016] The pushing electromagnet is connected to the control module, which controls its on / off state and the magnitude of its thrust, so as to push the dynamic connection unit to move in the direction of high resistance when the voltage of the power supply increases;

[0017] The reset unit is located between the pushing unit and the dynamic connection unit, and is connected to the pushing electromagnet and the dynamic connection unit respectively. The reset unit is a memory alloy pull rope, which drives the dynamic connection unit to reset to a low resistance area when the voltage of the power supply decreases.

[0018] Preferably, the protection unit comprises: an insulator and a protection magnet provided on the top of the insulator;

[0019] The protective magnet is connected to the control module. When the monitoring module detects that the voltage exceeds the limit, the control module sends a trigger signal to the protective magnet, causing its magnetic pole to reverse and adsorb to the dynamic connection unit, cutting off the power supply circuit through the insulator to achieve power-off protection for the CPU.

[0020] Preferably, the transient regulation module is an LLC resonant compensation circuit, which is used to perform transient voltage regulation when the voltage fluctuation exceeds a threshold value, and its resonance parameters are dynamically associated with the CPU temperature and current.

[0030] When the temperature or load changes suddenly, the resonant frequency changes adaptively to suppress transient voltage surges;

[0031] When the CPU temperature or load exceeds the safety threshold, the LLC resonant compensation circuit synchronously triggers the protection unit to cut off the power supply, and the control module is forced to switch to the mechanical contact resistance adjustment mode, and a hard power-off is achieved through the adsorption of dynamic contacts and protective magnets.

[0032] Preferably, the control module determines the regulation decision according to the voltage fluctuation value in the following specific implementation process:

[0033] The control module selects the regulation mode based on the weighted value W of the voltage fluctuation amplitude ΔV and the duration Δt:

[0034] If W>threshold, start the instantaneous regulation module;

[0035] If W≤threshold, start the continuous adjustment module.

[0036] The beneficial effects of this application are:

[0037] In this application, the monitoring module and the regulating module are connected respectively through the control module. The control module automatically selects the instantaneous regulating module or the continuous regulating module to perform voltage regulation based on the power supply voltage, CPU temperature and CPU load current value collected in real time by the monitoring module. The regulating module includes an instantaneous regulating module and a continuous regulating module connected in parallel, and the dual-mode is dynamically switched to reasonably select the regulation mode according to the change of the power supply voltage.

[0038] The present application realizes continuous adjustment of the CPU power supply voltage by linearly sliding the dynamic connection unit on the variable resistance part, wherein the resistance values ​​of the variable resistance part are distributed in an arithmetic / geometric sequence, thereby improving the adjustment accuracy;

[0039] In this application, the drive unit adopts a method of pushing the combination of electromagnet and memory alloy pull rope, so that when the voltage increases, the electromagnet drives the contact to move toward the high resistance end to increase the voltage divider; when the voltage decreases, the memory alloy pull rope automatically resets the contact to reduce the voltage divider, forming a closed-loop feedback control to ensure that the power supply voltage remains constant within a wide load range.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see the attached Figure 1-3 , provides a system for reducing computer power consumption, the system comprising: a control module, a monitoring module and a regulation module arranged between the power supply and the CPU.

[0048] The control module includes a continuous control module and a transient control module connected in parallel; two ends of the continuous control module and the transient control module are connected to the CPU and the power supply respectively.

[0049] The continuous adjustment module includes: a driving unit, a variable resistance unit, a dynamic connection unit located on the variable resistance unit, and a protection unit located on the side of the variable resistance unit facing away from the driving unit;

[0050] The connecting substrate is connected to the power supply;

[0051] The resistance changing unit includes a connecting substrate and a resistance changing portion located on the connecting substrate;

[0052] The variable resistor portion includes a plurality of unit resistors with different resistance values ​​and insulating plates located between adjacent unit resistors; the unit resistors with different resistance values ​​and the insulating plates are alternately arranged to form the variable resistor portion; the unit resistors are linearly or nonlinearly distributed in a descending order or a descending order, and are connected to the connection substrate; the linear arrangement means that the unit resistor values ​​are distributed in an arithmetic sequence, which is suitable for steady-state load scenarios; the nonlinear arrangement means that the unit resistor values ​​are distributed in an exponential or logarithmic order, which is suitable for dynamic load mutation scenarios;

[0053] The driving unit is connected to the dynamic connection unit, the driving unit and the protection unit are respectively connected to the control module, the driving unit and the protection unit are respectively located at two ends of the entire variable resistance unit, and the driving unit and the protection unit are respectively located on the opposite sides of the unit resistor with the smallest resistance value and the unit resistor with the largest resistance value in the variable resistance unit;

[0054] The connecting substrate 7 is connected to the unit resistor 5 and the CPU respectively;

[0055] The dynamic connection unit 2 is located on a connection surface formed by alternating arrangement of unit resistors 5 and insulating plates 8 of different resistance values. The dynamic connection unit 2 is connected to the CPU via a connecting wire 6 and moves along the connection surface toward the side where the resistance value increases or decreases. By contacting the unit resistors of different resistance values, the dynamic connection unit slides in the direction of increasing resistance of the variable resistor to respond to voltage increases, and resets in the direction of decreasing resistance to respond to voltage decreases, based on the real-time changes in the power supply voltage. Specifically, when the power supply voltage increases, the electromagnet generates a magnetic field repulsion force with the same polarity as the dynamic connection unit, driving the dynamic connection unit to move toward the high-resistance unit resistor, thereby increasing the series resistance voltage divider to reduce the CPU input voltage; when the power supply voltage decreases, the memory alloy pull rope contracts due to the temperature drop, pulling the dynamic connection unit to reset toward the low-resistance unit resistor, thereby reducing the series resistance voltage divider to increase the CPU input voltage, thereby maintaining a constant input voltage.

[0056] In this embodiment, the different resistance values ​​of the unit resistors 5 are achieved by the thickness of each unit resistor. The resistance value of the unit resistor increases linearly with the thickness, and the height of the insulating plate is determined by the thickness of the two adjacent unit resistors. This allows the unit resistors and insulating plates to be alternately arranged to form a variable resistance portion in a right-angled trapezoidal structure. The connecting substrate is located at the bottom of the horizontal right-angled side of the right-angled trapezoidal structure; the driving unit and the protection unit are located on either side of the upper and lower bases of the right-angled trapezoid, respectively; and the dynamic connection unit is slidably connected to the inclined surface of the right-angled trapezoidal structure. The dynamic connection unit slides along the inclined surface in a direction opposite to the change in the supply voltage (moving toward the high resistance end when the voltage increases and resetting to the low resistance end when the voltage decreases).

[0057] The driving unit includes a pushing magnet and a reset unit; the reset unit is located between the pushing magnet and the dynamic connection unit, and the two ends of the reset unit are respectively connected to the pushing magnet and the dynamic connection unit.

[0058] Wherein, the dynamic connection unit is a magnet;

[0059] like Figure 4 As shown, the pushing magnet 9 is an electromagnet, which is connected to the control module, and the magnitude of its current is positively correlated with the supply voltage: when the supply voltage increases, the control module increases the current of the pushing magnet 9, so that it generates a stronger magnetic field repulsion (i.e., the force shown in the horizontal direction). Since the magnetic field repulsion is the same pole as the dynamic connection unit 2, and the dynamic connection unit 2 is slidingly connected to the variable resistance part, based on the repulsion of the same poles, the pushing magnet 9 pushes the connection unit 2 along the variable resistance toward the high resistance direction (uphill) through the magnetic field repulsion (i.e., the force shown by the inclined surface in the figure); when the supply voltage decreases, the control module reduces the current of the pushing magnet, and the reset unit 1 pulls the dynamic connection unit 2 to reset toward the low resistance direction (downhill);

[0060] The reset unit 1 is a memory alloy that deforms according to the magnitude of the power supply voltage. Specifically, as the output voltage of the power supply increases, the tension of the dynamic connection unit increases. As the output voltage of the power supply decreases, the temperature decreases, and the dynamic connection unit is pulled downhill (sliding toward the unit resistance on the side with reduced resistance), thereby compensating for the continuously decreasing output voltage of the power supply.

[0061] In this application, the dynamic connection unit is driven to move toward the high resistance direction by pushing the electromagnet through the magnetic pole repulsion force (the same magnetic pole as the dynamic connection unit); the reset unit contracts due to the drop in temperature when the voltage decreases, pulling the contact to reset toward the low resistance direction, thereby ensuring that the voltage delivered to the CPU remains constant.

[0062] The protection unit includes an insulator 4 and a protection magnet 3;

[0063] The insulator 4 in the protection unit is located on the side of the unit resistor 5 with the largest resistance in the variable resistance section that faces away from the drive unit. When the monitoring module detects that the output voltage of the power supply exceeds 120% of the rated value, the control module sends a trigger signal to the protection magnet 3, causing its magnetic pole to be opposite to that of the dynamic connection unit 2, thereby achieving adsorption between the magnet and the dynamic connection unit 2. The power supply circuit is cut off through the insulator 4, achieving power-off protection for the CPU.

[0064] The protective magnet 3 is installed on the top of the insulator, the protective magnet and the dynamic connection unit are located on the same plane, and the magnetic pole of the protective magnet 3 is opposite to the magnetic pole of the pushing unit;

[0065] The magnetic pole of the dynamic connection unit 2 is opposite to the magnetic pole of the protection magnet and the same as the magnetic pole of the pushing unit.

[0066] When the output voltage of the power supply exceeds the safety value, the dynamic connection unit moves into the magnetic attraction range of the protective magnet, and the dynamic connection unit is magnetically connected to the protective magnet. At this time, the dynamic connection unit is connected to the power supply through the insulator at the bottom of the protective magnet, and is disconnected from the CPU, thereby achieving power-off protection for the CPU.

[0067] In this embodiment, the protective magnet and the pushing magnet are respectively located at the highest point and the lowest point of the inclined surface of the right-angled trapezoidal structure, so as to prevent the dynamic connection unit from falling off from the variable resistance part while achieving their respective functions.

[0068] The instantaneous adjustment module is an LLC resonance compensation module.

[0069] The equivalent value of the resonant inductance Lr in the LLC resonant compensation module is dynamically adjusted through a core-adjustable inductor. The control module adjusts the switching frequency (range: 50kHz to 500kHz) in real time based on the CPU temperature and current fluctuation signals collected by the monitoring module, suppressing transient voltage fluctuations (response time ≤ 1μs).

[0070] In this embodiment, the connection substrate is made of a high thermal conductivity copper alloy;

[0071] The dynamic connection unit uses gold-plated conductive contacts with a graphene coating on the surface to reduce friction loss. The push electromagnet is an electromagnet connected to the control module, which generates a magnetic field force (such as electromagnetic attraction or repulsion) to drive the dynamic connection unit to slide along the variable resistance part.

[0072] The unit resistor is made of carbon film material, and the thickness is adjusted through laser etching process. The resistance value increases linearly with the thickness.

[0073] The current driving the magnet is positively correlated with the supply voltage.

[0074] The reset unit is a nickel-titanium alloy memory rope, with the two ends respectively connected to the pushing electromagnet and the dynamic connection unit. When the power supply voltage decreases, the control module reduces the current of the pushing electromagnet. The memory rope shrinks due to the drop in temperature, pulling the dynamic connection unit to reset toward the low resistance direction of the variable resistance part, reducing the series resistance to increase the CPU input voltage.

[0075] Example 2

[0076] A method for reducing computer power consumption, characterized by adopting the system for reducing computer power consumption according to any one of claims 1 to 6, comprising the following steps:

[0077] S1: The monitoring module collects the output voltage, CPU temperature and current data of the power supply in real time;

[0078] S2: The control module determines a control decision based on the voltage fluctuation value and selects a control module according to the control decision;

[0079] S3, the selected control module performs corresponding adjustments to maintain the stability and safety of the CPU power supply voltage;

[0080] The regulatory decisions include:

[0081] If the fluctuation value exceeds the threshold range, the transient regulation module is activated to perform transient voltage compensation;

[0082] If the fluctuation value is within the threshold range, the continuous adjustment module is started to adjust the output voltage by adjusting the resistance.

[0083] Furthermore, transient voltage compensation is achieved through an LLC resonant compensation circuit, and the specific implementation process is as follows:

[0084] Dynamically bind the equivalent inductance (Lr) of the LLC resonant compensation circuit to the preset CPU temperature threshold and the CPU load current;

[0085] The equivalent inductance (Lr) of the LLC resonant compensation circuit is dynamically associated with the CPU temperature (T) and the load current (I), specifically satisfying:

[0086] Wherein, k is the preset proportional coefficient;

[0087] When the temperature or load changes suddenly, the resonant frequency changes adaptively to suppress transient voltage surges.

[0088] Among them, when the CPU temperature or load exceeds the safety threshold, the LLC resonant compensation circuit synchronously triggers the protection unit to cut off the power supply, and the control module is forced to switch to the mechanical contact resistance adjustment mode, and a hard power-off is achieved through the adsorption of dynamic contacts and protective magnets.

[0089] The specific process is:

[0090] In this embodiment, the CPU temperature is collected by a high-precision thermistor, and the CPU load current is collected by connecting a high-precision current sampling resistor in series with the CPU power supply circuit;

[0091] A high-precision thermistor (specifically, an NTC negative temperature coefficient thermistor) is placed closely near the CPU core, leveraging its temperature-dependent resistance to create a voltage divider circuit. The divided analog voltage signal is connected to the control module's ADC pin, where it is converted to a digital value. This digital value is then converted to the corresponding temperature value, T, based on the thermistor's characteristic curve and calibration parameters. To improve the accuracy and stability of temperature acquisition, multiple sampling and averaging are used, and the collected data is filtered to remove high-frequency noise.

[0092] A high-precision current sampling resistor (specifically a constantan wire resistor) is connected in series with the CPU's power supply circuit. The current signal is acquired by exploiting the proportional relationship between the voltage drop across the resistor and the current flowing through it. The voltage difference across the sampling resistor is amplified by an instrumentation amplifier and then connected to the control module's ADC pin for digital conversion. Similarly, the collected current data is sampled, averaged, and filtered multiple times to obtain the accurate effective value of the supply current, I.

[0093] After the control module is powered on, the internal registers, ADC sampling parameters, and proportional coefficient k are initialized to ensure that the system is in a stable initial state.

[0094] The control module starts the ADC to sample the temperature and current signals at fixed time intervals, obtains the latest T and I values, and updates them to the internal data storage area.

[0095] According to the collected T and I values, substitute into the formula , calculate the equivalent inductance Lr required by the LLC resonant compensation circuit under the current working conditions.

[0096] The control module generates a corresponding PWM (pulse width modulation) control signal based on the calculated Lr value, and adjusts the on and off time of the switch tube in the LLC resonant compensation circuit through the drive circuit, thereby changing the equivalent inductance of the circuit and realizing dynamic adjustment of the resonant parameters.

[0097] The system monitors the CPU's operating status and the stability of the power supply voltage in real time. If a power supply anomaly is detected (e.g., voltage fluctuations outside the allowable range), it fine-tunes the proportional coefficient k, recalculates the Lr value, and adjusts the control signal to optimize the system's compensation. Simultaneously, it uploads system operating data (such as temperature, current, and Lr value) to the monitoring terminal, allowing users to monitor the device's operating status in real time.

[0098] By implementing the above-mentioned temperature and current correlation algorithm, the control module can achieve precise control of the LLC resonant compensation circuit, effectively improving the adaptability and stability of the system under different working conditions and ensuring the reliable operation of the CPU.

[0099] Furthermore, the control module determines the regulation decision according to the voltage fluctuation value in the following specific implementation process:

[0100] The control module selects the regulation mode based on the weighted value W = α·ΔV + β·Δt of the voltage fluctuation amplitude (ΔV) and duration (Δt):

[0101] If W>Wth (threshold), start the instantaneous adjustment module;

[0102] If W≤Wth (threshold), start the continuous adjustment module.

[0103] In this application, the intelligent module uses the weighted value W = α·ΔV + β·Δt to intelligently determine the regulation mode: when the voltage fluctuation amplitude ΔV or duration Δt exceeds the threshold Wth (such as sudden transient interference), the LLC resonant compensation circuit is preferentially enabled for transient response; when the fluctuation is within the steady-state range, it switches to the continuous regulation module and achieves low-power precision control through mechanical resistance adjustment. This mechanism avoids the limitations of a single mode under complex working conditions, allowing the system to dynamically balance "fast response" and "energy efficiency optimization", and improves energy efficiency by a corresponding speed compared to traditional single regulation schemes.

[0104] The voltage fluctuation threshold range is dynamically adjusted based on real-time CPU core temperature and load current. For example, under high-temperature conditions, the threshold is automatically tightened (Wth is reduced) to trigger the protection mechanism earlier; under light-load and low-temperature conditions, the threshold is relaxed to reduce the switching frequency of the regulation module to reduce losses.
