The present invention claims priority from application no. 201811260026.4 for a Chinese patent filed with the National Intellectual Property Administration of China on October 26, 2018, entitled “Hibernation method and apparatus for a power supply, method and apparatus for determining the hibernation of a power supply, and a hibernation apparatus,” the entire contents of which are incorporated herein by reference .

Technical field

Embodiments of the present invention relate to the field of communications, in particular to a hibernation method and apparatus for a power supply, a method and apparatus for determining hibernation of a power supply, and hibernation tools.

State of the art

Due to the constant increase in the volume of communication services, system requirements for the power of the power supply are gradually increasing. To meet these demands, the power supply capacity is becoming larger and larger, but at the same time it is becoming more and more difficult for independent power supplies to provide power on their own. As a result, there is a strong trend towards the use of parallel power supply mode in power supply, which has become widespread due to the ease of configuration changes and operational reliability.

As the power supply is used in a communication device, while taking into account the reliability of the power supply, power management is evolving towards saving power from the power supply. Improving power supply efficiency is the most intuitive and technically demanding energy saving tool, and accordingly, the industry is striving to improve power supply efficiency through complete power system management. In particular, for a parallel power supply system, the prior art proposes a cold backup control method. In this control method, according to the load condition of the system, some power supplies are signaled to enter the cold standby state, and the output voltage of these power supplies is reduced until power generation stops, thereby increasing the load intensity of other power supplies operating in normal mode and increasing overall power system efficiency. In addition, being an important factor and coefficient of system control dynamism, the load is not applied to the above control strategy. If reliability is taken into account in the control method, and the number of operating power supplies is reserved according to the rated load, the energy saving effect will be affected. If only a small number of power sources are used to achieve the maximum energy saving effect, there is a risk of reduced power supply reliability. In addition, the cold standby concepts involved in the two control methods only reduce the output voltage to cut off power to the system, but the entire circuit still remains operational and consumes power, which is essentially no-load loss. Based on the above analysis, it can be concluded that there is a problem that improving the overall energy saving effect of the power supply system only by increasing the load intensity of the power supply is not obvious in the prior art.

This embodiment proposes a hibernation method for a power supply that can be implemented in the above mobile terminal. In fig. 2 is a flowchart of a hibernation method for a power supply according to an embodiment of the present invention. As shown in FIG. 2, the process flow includes step S202, which is described in detail below.

In step S202, the power supply hibernation device selects one or more power supplies to enter the hibernation mode according to information about each power supply in the parallel power supply system. In an embodiment, the power source information includes at least: an input power type of the power source and a conversion efficiency of the power source.

In at least one exemplary embodiment, power supply information may be collected through the following modes.

In at least one exemplary embodiment, information about the power input type of the power source may be obtained through the following mode: after each power source completes its evaluation of the corresponding power input type, the hibernation device for the power source instructs each power source to make a request via a communication channel. about the type of electric power input of each power supply to complete the collection of information about the type of electric power input of each power source.

In at least one exemplary embodiment, information about the conversion efficiency of the power source may be collected through the following mode. A load efficiency curve group measuring temperature and input voltage as a separate parameter can be preset at the factory for each power supply. During field operation, the power supply can determine the efficiency according to the actual operating conditions, and the efficiency determination result can be compared with the preset efficiency curve group for calibration, and the adjustment of the standard load efficiency curve group is carried out using these calibration data as a reference points to achieve self-tuning of the load curve. Each power supply obtains the conversion efficiency, due to the fact that the type of input electricity and the input voltage level of the power supply in the parallel power supply system may be different, and the input voltage has a great influence on the efficiency of the power supply, while obtaining the conversion efficiency of the power supply efficiency curve The load can be selected according to the input voltage value, and then the conversion efficiency of the power supply is determined according to the system load. Through the communication channel, each power supply is commanded to query the conversion efficiency of each power supply to complete the collection of information about the conversion efficiency of each power supply.

In at least one exemplary embodiment, the hibernation device for the power source presets an efficiency prioritization table for the type of power input in accordance with system application scenarios. The power supply hibernation device determines the number of power supplies that should go into hibernation mode and selects the power supplies that should go into hibernation mode according to the type of power input and the conversion efficiency of each system power supply in combination with the load condition of the system.

In at least one exemplary embodiment, due to the fact that the type of electric power input of each power supply and the conversion efficiency of each power supply may be the same or different, a hibernation mode is proposed for the following four conditions.

(1) In the case where the power supplies in the parallel power supply system have the same type of power input and the same conversion efficiency, the power supply hibernation device selects, according to the operation information of each power supply, one or more power supplies to enter the hibernation.

In at least one illustrative embodiment, the operating information includes at least the operating time of each power supply and/or the operating temperature of each power supply.

For example, given that there are two power supplies that have lasted longer than the other power supplies in a parallel power supply system, then in order to reduce wear on the devices in the power supplies, these two power supplies can be selected as candidates for switching to the parallel power supply mode. hibernation. Provided that the remaining power supplies in the parallel power supply system can perform as required, the two candidate supplies enter hibernation mode. Under the condition that the operation of the power supplies currently running cannot meet the performance requirements, the power supply with the longer runtime of the two power supplies enters hibernation mode, and the power supply with the shorter runtime continues to operate.

Another example: given that there are four power supplies whose operating temperature is higher than the other power supplies in the parallel power supply system, then in order to cool the entire parallel power supply system, these four power supplies can be selected as candidate supplies for transition to hibernation mode. Assuming that the remaining power supplies in the parallel power supply system can perform as required, the four candidate supplies enter hibernation mode. Provided that the operation of the currently operating power supplies cannot meet the performance requirements and an additional power supply is required to continue operation, one candidate power supply to enter hibernation mode with the lowest operating temperature of the four candidate sources to enter in hibernation mode continues to operate, and the other three candidate sources with a higher operating temperature enter the hibernation state.

It should be noted that based on actual needs, one or more power supplies that should enter the hibernation state can be determined in combination with the operating time of the power supply and the operating temperature of the power supply. Moreover, reference to other operating information in determining one or more power supplies to enter a hibernation state is also within the scope of the present embodiment.

(2) In the case where the power supplies in the parallel power supply system have different types of power inputs and the same conversion efficiency, the power supply hibernation device selects, according to the type of power inputs of each power supply, one or more power supplies to enter the mode hibernation.

In at least one exemplary embodiment, the hibernation device for a power supply receives the input power type of each power source and sorts the input power efficiency of the power supplies according to the input power type of each power source. The power supply hibernation device selects, in accordance with the sorting result of the power input efficiency of the power supplies and the power input state of each power supply, one or more power supplies whose electric power efficiency is lower than a predetermined efficiency threshold value as one or more power supplies to switch into hibernation mode.

In at least one exemplary embodiment, a hibernation device for a power supply may sort the power input efficiency of the power supplies in the following two ways.

1) Sorting can be done based on the power loss of the power source. The difference between the input voltage types of power supplies has a great impact on the power loss of power supplies. For example, if an AC power supply supplies power in AC input mode, the power supply must undergo two-stage conversion when delivering DC current. If the AC power supply supplies power in high voltage DC input mode, the power supply should only undergo one-step conversion when outputting DC current, so that the DC power loss of the power supply is less.

2) Sorting can be performed based on an assessment of the input efficiency of power supplies. For example, AC input is directly from the grid, while high voltage DC input is through AC-DC conversion, and accordingly, the efficiency of AC input power is higher than the efficiency of high voltage DC input power.

In at least one exemplary embodiment, the hibernation device for a power supply obtains information about the efficiency of the type of electrical input of each power supply, then sorts the efficiency of the input electrical energy of the power sources and selects one or more power supplies in increasing order as one or more power supplies that should switch into hibernation mode.

For example, given that ten parallel output power supplies are included in a parallel power supply system and only four power supplies are required to satisfy the load system requirements, the power input efficiency of the power supplies is sorted in ascending order starting from the power supply corresponding to the lowest efficiency power input, power supplies corresponding to an input power efficiency that is lower than or equal to one fourth of the input power efficiency are selected to stop operating and are the power supplies to enter hibernation mode.

It should be noted that the preset efficiency threshold can be adjusted in real time based on the needs of the load system.

In addition, to enhance reliability, each power supply can automatically detect its input voltage type, and then the power input efficiency of the power supplies can be determined and sorted according to the determination result provided by each power supply.

(3) In the case where the power supplies in the parallel power supply system have the same type of power input and different conversion efficiencies, the conversion efficiencies of the power supplies are sorted; and selecting one or more power supplies in increasing order as the one or more power supplies to enter hibernation mode.

In at least one illustrative embodiment, the difference in efficiency is apparent in a system where power supplies of different efficiency levels are used. In a system using power supplies of the same efficiency level, the difference in efficiency is mainly due to individual differences.

For example, given that eight parallel output power supplies are included in a parallel power supply system and only five power supplies are required to satisfy the load system requirements, the conversion efficiencies of the power supplies are sorted in ascending order, starting with the power supply corresponding to the lowest conversion efficiency ,power supplies corresponding to a conversion efficiency that is lower than or equal to the fifth conversion efficiency are selected to stop operating and are the power supplies that should enter hibernation mode.

In at least one exemplary embodiment, the hibernation device for a power supply sorts the conversion efficiencies of the power supplies according to the efficiency level of each power supply.

It should be noted that, provided other factors are identical, the conversion efficiency of a power supply with a higher input voltage is higher than the conversion efficiency of a power supply with a lower input voltage. Thus, the input power level can be accessed when the power supply conversion efficiency is sorted.

(4) In the case where the power supplies in the parallel power supply system have different types of power input and different conversion efficiencies, the hibernation device for the power supply comprehensively selects, according to the type of power input and the conversion efficiency of each power supply, one or more power supplies that should go into hibernation mode.

In at least one exemplary embodiment, similar to the methods described in paragraphs (2) and (3), in the case that the power supplies in the parallel power supply system have the same type of power input and different conversion efficiencies, the hibernation device for the power supply can comprehensively take into account the sorting result obtained after sorting the power input efficiencies of the power supplies according to the input electric power type of each power supply, and the sorting result obtained after sorting the conversion efficiencies of the power supplies.

In at least one exemplary embodiment, after selecting power supplies to enter hibernation mode, those selected power supplies are notified one by one to satisfy the power saving requirement.

Through the description of the above embodiments, those skilled in the art can understand that the method of the above embodiment can be implemented using software plus the necessary general purpose hardware platform and, of course, can also be implemented using hardware, but in many cases the first implementation is the best option. Based on this understanding, the essence of the technical solution in the embodiments of the present invention, or, in other words, part of the technical solutions complementary to the traditional state of the art, can be implemented in the form of a software product stored on a storage medium (for example, in a read-only memory (ROM) / random access memory (RAM), magnetic disk, and optical disk), including a series of instructions for turning on an end device (which may be a mobile phone, computer, server, or network device, etc.) to implement the methods described in various embodiments of the present invention.

Embodiment 2

This embodiment provides a method for determining power supply hibernation, which can be implemented in a mobile terminal similar to that used in Embodiment 1, and the described details will not be repeated. FIG. 3 is a flowchart of a method for determining power supply hibernation in accordance with an embodiment of the present invention. As shown in FIG. 3, the process flow includes step S302, which is described in detail below.

In step S302, the parallel power supply system determines a hibernation mode into which one or more power supplies in the parallel power supply system enters according to the load information of the load system being supplied with power, wherein the one or more power supplies are determined according to with power supply information obtained from each power supply in the parallel power supply system, and the power supply information includes at least: an input electric power type of the power supply and a conversion efficiency of the power supply.

In at least one exemplary embodiment, after the power supply receives an instruction to enter hibernation mode, the power supply in the parallel power supply system monitors load information of the load system to which the parallel power supply system is supplying power and determines the flow of the load.

In at least one exemplary embodiment, a hibernation device for a power supply may determine a hibernation mode into which one or more power supplies should enter, as follows. One or more power supplies determine whether the load system load flow meets the hibernation threshold. If the determination determines that the load system load flow meets the hibernation threshold, one or more power supplies enter a hibernation mode corresponding to the hibernation threshold.

In at least one exemplary embodiment, if one or more power supplies determine that the load flow of the load system meets a first hibernation threshold, the output voltage is reduced.

In at least one exemplary embodiment, if one or more power supplies determines that the load flow of the load system meets a second hibernation threshold, the one or more power supplies enters a second hibernation mode and turns off the output voltage.

In at least one example embodiment, the second hibernation threshold value is lower than the first hibernation threshold value.

In the event that one or more power supplies entering the second hibernation mode determines that the load system load flow increases and meets the third hibernation threshold, the one or more power supplies enters the first hibernation mode and reduces the output voltage, at which the third threshold value hibernation is the sum of the second hibernation threshold and the load flow increment.

It should be noted that to prevent fluctuations in the second threshold value, the third hibernation threshold value is different from the second threshold value.

In at least one exemplary embodiment, if one or more power supplies entering hibernation mode determines that the load system load flow increases and meets the fourth hibernation threshold, the one or more power supplies wake up from hibernation mode and restore output operating voltage, wherein the fourth hibernation threshold value is the sum of the first hibernation threshold value and the load flow increment.

In at least one exemplary embodiment, when electrical power is consumed daily to ensure normal load operation during the summer, the terminal equipment containing the load system must be cooled, such that the load system's power demand is typically much higher than during other periods. . Thus, a sharp increase and decrease in the power demand of the load system is inevitable. Moreover, in daily life, the power demand is high during the morning and afternoon working hours, while the power demand is low at noon and evening. Thus, changes in the power demand of the load system are also very significant during operating hours. Therefore, in actual use, the power supply demand of the load system is unstable. If the equipment enters hibernation mode in response to changes in overall power demand, on the one hand, other operating power supplies may be overloaded, resulting in a high failure rate in the parallel power supply system, and on the other hand, power may be lost. Thus, to solve the above problems, the power supply in an operating state can directly determine compliance with the first hibernation threshold without determining compliance with the second hibernation threshold. In addition, when the power supply is unstable, the power supply in the second hibernation mode may also skip the determination of compliance with the third hibernation threshold and directly determine compliance with the fourth hibernation threshold in order to adapt to the operating power demands.

Provided that the power supply entering the second hibernation mode determines that the load flow increment rate exceeds the preset increment rate threshold, it means that the load system's power demand is high, after which the power supply can adaptively reduce the third hibernation threshold value ( but not lower than the second hibernation threshold) according to the actual value of the load flow increment rate, so that the power supply can enter the first hibernation mode in advance. On the other hand, provided that the power supply entering the second hibernation mode determines that the load flux increment rate is below a predetermined increment rate threshold, this means that the load system's power demand is maintained at a slowly increasing level, and the power demand can be reduced at any time, the power supply can adaptively increase the third hibernation threshold (but not above the first hibernation threshold).

Additionally, provided that the power supply entering hibernation mode detects that the load system's load flux increment rate is much greater than a predefined increment rate threshold, this means that the load system is in emergency mode, requiring power supply at full load of the parallel system. power supplies, after which the power supply can exit hibernation mode and enter operating mode.

In at least one exemplary embodiment, a common hibernation signal is connected between the power supplies. The common hibernation signal may indicate that the power supplies are in a normal state during normal startup, and when a failure occurs, the failed power supply, through the common hibernation signal, transmits corresponding information to the other power supplies. Each power supply needs to monitor the overall hibernation signal in real time. In at least one exemplary embodiment, one or more power supplies entering hibernation mode determines whether a common hibernation signal is provided between the power supplies if a failure is detected. If a common hibernation signal is determined to be issued when a fault is detected, one or more power supplies entering hibernation mode wakes up from hibernation mode and restores output operating voltage.

In at least one exemplary embodiment, the one or more power supplies with the output operating voltage restored determine whether a common hibernation signal is provided between the power supplies during normal operation. If the common hibernation signal is determined to be present during normal operation, one or more power supplies with output operating voltage restored re-enters hibernation mode.

In at least one exemplary embodiment, if a running power supply fails, the running power supply sets the hibernation signal common to the power supplies to a low level (typically determined by logic 0) and informs the hibernating power supply of such failure via a common hibernation signal. When the power supply entering hibernation mode detects a high level common hibernation signal, the problem of insufficient power supply in the running parallel power supply system is displayed. After the power supply entering hibernation mode stores the information related to hibernation mode, the power supply exits hibernation mode and restores the output operating voltage to supply power to the load system.

In at least one illustrative embodiment, in the event that a running power supply returns to normal operation, the running power supply may set a hibernation signal common to power supplies to a high level (usually determined by logic 1), indicating that the power supply that is restoring output operating voltage to supply power to the load system, no longer needs to supply power to the load system. Thus, these power supplies, which restore the output operating voltage to supply power to the load system, enter the appropriate hibernation mode in accordance with the previously stored hibernation mode information. This reduces energy losses.

For a better understanding of the above-described embodiments, the following scenarios are proposed.

Scenario 1:

The server system is powered by four power supplies installed on the server backplane. Four parallel power supplies form an embodiment of the described power supplies, and a server backplane forms an embodiment of an interface unit and is provided with a G2C communication interface, a common hibernation signal, and a bus detection signal. The control unit is built into the server system. The server issues a hibernation command to the parallel power supply or requests information about the operating status of the power supply through the system backplane using the I2C communication interface. The power supplies in a parallel power supply system are connected to each other through a common hibernation signal, and if any power supply fails, the common hibernation signal will activate the power supply that is in hibernation mode. In this case, the power supplies in the parallel power supply system are connected to each other through a bus detection signal to control the load of the system. The power input types of all system power supplies are AC input, and the power supply supports differential hibernation. In fig. 4 is a flowchart of differential hibernation control in accordance with an embodiment of the present invention.

As shown in FIG. 4, when the flow is found to be only A% of the full load flow, i.e. reaches the first hibernation threshold, the two power supplies are commanded to enter a first hibernation mode, in which the power supplies reduce their output voltage to stop supplying power to the system, and the system is powered by the other power supplies operating in normal mode. When a power supply entering hibernation mode detects through the bus detection signal that the running server system flux becomes less than B% of full load flux, i.e. reaches the second hibernation threshold (note: V<A), the power supply in hibernation mode turns off the output voltage and goes into standby state, i.e. The power supply in hibernation mode enters a deep hibernation state. The power supply, while in deep hibernation mode, continues to monitor the system load through the bus detection signal and transitions back from the second hibernation mode to the first hibernation mode when the flow increases to (B+C)% of the full load flow, i.e. reaches the third deep hibernation threshold, at which the power supply, while in hibernation mode, reduces the output voltage. If the flow continues to increase to (A+D)% of full load flow, i.e. reaches the fourth hibernation threshold, the power supply in the second hibernation mode automatically wakes up from hibernation mode, restores the output voltage to rated voltage, and this power supply and the previously operating power supplies share current to supply power to the system. If the server flow is reduced again to A% of the full load flow, i.e. reaches the first hibernation threshold, the power supply that previously received the hibernation command automatically enters the hibernation state again and continues to operate according to the above procedure. If any of the operating power supplies fail and are unable to supply power, the common hibernation signal level is reduced, and the power supply that is in hibernation mode can immediately exit hibernation mode when it detects a low common hibernation signal level. When the common hibernation signal is restored to a high level, the power supply that was in hibernation mode returns to the hibernation state.

If any of the operating power supplies fail and are unable to supply power, the common hibernation signal level is reduced, and the power supply that is in hibernation mode can immediately exit hibernation mode when it detects a low common hibernation signal level. When the common hibernation signal is restored to a high level, the power supply that was in hibernation mode returns to hibernation mode.

When it is necessary to exit the hibernation state, the power supply that is in the hibernation mode can be commanded to exit the hibernation mode through a G2C communication command.

Scenario 2:

The server system is powered by four power supplies installed on the server backplane. Four parallel power supplies form an embodiment of the described power supplies, and a server backplane forms an embodiment of an interface unit and is provided with a G2C communication interface, a common hibernation signal, and a bus detection signal, which are connected to each power supply. The control unit is built into the server system.

1) In this example, the two power supplies in the parallel power supply system are AC input, and the two power supplies are high voltage DC input. The server system requests information about the input voltage types of power supplies through a communication command, and determines according to the previously stored corresponding relationship between the input voltage type and the high efficiency mode, that the high efficiency input mode is an AC input, and the high voltage DC input has a lower efficiency than AC input.

2) The system detects that two power supplies need to enter hibernation mode, selects DC input power supplies to enter hibernation mode according to the input voltage types of power supplies, and AC input power supplies continue to supply power to the system . The server system sends a communication command to the two DC-input power supplies to enter hibernation mode. These two power supplies entering a second hibernation mode reduce their output voltage and stop supplying power to the system load.

3) Power supplies that are in hibernation mode monitor the overall hibernation signal throughout the process. When power supplies in hibernation mode detect that the overall hibernation signal level has decreased, they can immediately exit hibernation mode, but the hibernation control instructions must be retained. When power supplies that are in hibernation mode detect that the common hibernation signal has returned to a high level, those power supplies enter hibernation mode again.

Scenario 3:

The server system is powered by four power supplies installed on the server backplane. Four parallel power supplies form an embodiment of the described power supplies, and a server backplane forms an embodiment of an interface unit and is provided with a G2C communication interface, a common hibernation signal, and a bus detection signal, which are connected to each power supply. The control unit is built into the server system.

In this example, the power input types of all power supplies of the parallel power supply system are AC input, and the conversion efficiency levels are different. Two power supplies are titanium high efficiency server power supplies, and the other two power supplies are platinum server power supplies. The communication equipment system requests data on the conversion efficiencies of power supplies through a communication command, and determines, in accordance with the previously stored corresponding relationship between the conversion efficiency of the power supply and the high efficiency mode, that the power supplies in the high efficiency mode are titanium power supplies, and the platinum power supplies have more low efficiency.

The system determines that the two power supplies need to enter hibernation mode, selects the platinum power supplies to enter hibernation mode according to the conversion efficiency of the power supplies, and the titanium power supplies continue the job of supplying power to the system. The communication hardware system commands the two platinum power supplies to enter hibernation mode via the I2C communication interface. These two power supplies entering hibernation mode reduce their output voltage and stop supplying power to the system load.

Power supplies that are in hibernation mode monitor the overall hibernation signal throughout the process. When power supplies in hibernation mode detect that the overall hibernation signal level has decreased, they can immediately exit hibernation mode, but the hibernation control instructions must be retained. When power supplies that are in hibernation mode detect that the common hibernation signal has returned to a high level, those power supplies enter hibernation mode again.

Scenario 4:

The server system is powered by four power supplies installed on the server backplane. Four parallel power supplies form an embodiment of the described power supplies, and a server backplane forms an embodiment of an interface unit and is provided with an I2C communication interface, a common hibernation signal, and a bus detection signal, which are connected to each power supply. The control unit is built into the server system.

1) In this example, two power supplies in the parallel power supply system have AC input, and the other two power supplies have high voltage DC input, the efficiency levels of the power supplies are different. Two power supplies are titanium high efficiency server power supplies, and the other two power supplies are platinum server power supplies. The control unit sorts the read conversion efficiencies of the power supplies according to a predefined efficiency prioritization table of the type of input power, then calculates a weighted average using the conversion efficiency and input efficiency of each power supply to obtain the total efficiency.

2) The system determines that two power supplies need to go into hibernation mode, selects power supplies with lower conversion efficiency to enter hibernation mode according to the full efficiency of the power supplies, and selects power supplies with higher conversion efficiency to continue operation. supplying power to the system. The communication hardware system, through the I2C communication interface, commands two power supplies with lower conversion efficiency to enter hibernation mode. After these two power supplies enter hibernation mode, hibernation control is carried out according to the hibernation control strategy similar to Scenario 1.

3) The power supply, while in hibernation mode, monitors the overall hibernation signal throughout the process. When power supplies in hibernation mode detect that the overall hibernation signal level has decreased, they can immediately exit hibernation mode, but the hibernation control instructions must be retained. When power supplies that are in hibernation mode detect that the common hibernation signal has returned to a high level, those power supplies enter hibernation mode again.
