Fig. 1 is a schematic diagram of a power supply system. In the power supply system 10, the power supply device 11 is configured to convert an external power (for example, 220v,50hz mains supply) input to the power supply device 11 into an operating voltage required by the electric device 12, so as to supply power to the electric device 12. The electric device 12 may be a communication device (for example, an access network device, a core network device, etc. in a mobile communication network), or may be a hardware device such as a server for supporting operation of services such as cloud computing, AI, etc.
In one related art, power may be supplied to powered device 12 in a manner that a fixed voltage is output to powered device 12 by power supply device 11. For example, currently in a communication room, a constant voltage of-53V is generally output to a communication device (i.e., powered device 12) by a power supply device (i.e., power supply device 11) to supply power to the communication device.
For the related art, on one hand, in the same load state, different voltages are used to supply power to the electric equipment, and consumed power is different. For example, as shown in table 1 below, when a communication device is powered by different voltages under a certain load condition, the power consumed by the communication device varies:
TABLE 1
Supply voltage Output current Power of Power variation
-54.3V 12.4A 673.32W 0.79％
-52.6V 12.7A 668.02W
-49.1V 13.4A 657.94W -1.51％
-44V 14.1A 620.4W -7.13％
When the power supply voltage is-52.6V, the output current of the power supply device is 12.7A, and the power consumed by the communication device is 668.02W; when the power supply voltage was increased to-54.3V, the output current of the power supply device was 12.4A, and the calculation revealed that the power consumed by the communication device was 673.32W, which was 0.79% higher than that when the power supply voltage was-52.6V. Similarly, when the supply voltage is reduced to-49.1V and-44V respectively, the power consumed by the communication device is 657.94W and 620.4W respectively by calculation using the supply voltage and the output current, and compared with the case that the supply voltage is-52.6V, the power is reduced by 1.51% and 7.13% respectively. It can be seen that in the example shown in table 1, the power of the communication device is minimal when the supply voltage is-44V, at which time the energy consumption is minimal.
On the other hand, in the case of different load states, the value of the supply voltage corresponding to the power of the consumer that is minimized may be different. For example, a powered device may achieve a minimum power with-53V power under load state a, while the powered device may achieve a minimum power with-49V power under load state b.
Therefore, if the electric equipment is powered by adopting a fixed voltage according to the scheme of the related art, the situation that the fixed voltage is not the most efficient power supply voltage may occur, and thus energy consumption is wasted.
Aiming at the technical problems, the embodiment provides a power supply method and a device. In the power supply method, the voltage for supplying power to the electric equipment can be dynamically adjusted. Specifically, when it is determined that the electric equipment meets the voltage regulation condition, determining a voltage (simply referred to as a first voltage) meeting the requirement of the electric equipment according to a dial testing method, and supplying power to the electric equipment by using the first voltage. In this way, the supply voltage of the consumer can be matched with the load state of the consumer. Thereby achieving the effects of reducing the power of the electric equipment and saving the energy consumption.
In order to achieve the effects of reducing the power of the electric equipment and saving the energy consumption, the power supply method provided by the embodiment is described in detail as follows:
in one embodiment, the periodic variation law of the load of the electric equipment is considered. Taking the base station device as an example, the base station device has a larger load during the daytime and a smaller load during the night. Therefore, the power supply voltage of the electric equipment can be dynamically adjusted, for example, the voltage adopted by the electric equipment for supplying power to the electric equipment once is determined according to the current load state of the electric equipment every interval (particularly every interval of one detection period), so that the determined voltage is adopted to supply power to the electric equipment, and the power of the electric equipment is reduced.
Specifically, as shown in fig. 2, the method specifically includes:
s201, the power supply device 11 determines a detection period.
In one implementation, the detection period may be a pre-configured value. For example, a day may be divided into a plurality of time periods in units of days. Wherein the above three periods may be set as one detection period, respectively. For example, a day may be divided into three time periods of 0 to 9 points, 9 to 17 points, 17 to 24 points. And in each time period, determining the voltage adopted for supplying power to the electric equipment according to the current load state of the electric equipment according to the following triggering of the content of S202.
In another implementation, the detection period may be determined by power device 11 based on a historical load state of powered device 12. For example, the load status (i.e., historical load status) of powered device 12 over a period of time may be monitored by power supply device 11; then, the power supply equipment 11 determines the load change rule of the electric equipment 12 according to the monitored historical load state; and then determining the detection period according to the load change rule.
Taking the electric equipment 12 as a base station equipment for example, the parameters reflecting the load of the electric equipment specifically include: the number of users in the current base station cell range, the number of calls, the data traffic flow and the like. The power supply device 11 may acquire the above parameters of the electric device 12 for a period of time, and determine a load change rule of the electric device 12 according to the above parameters, so as to determine a detection period.
Further exemplary, taking the electric equipment as a server running cloud computing, AI and other services as an example, the parameters reflecting the load of the electric equipment specifically include: parameters such as the size of the data quantity currently processed by the electric equipment, the utilization rate of hardware resources and the like. The power supply device 11 may acquire the above parameters of the electric device 12 for a period of time, and determine a load change rule of the electric device 12 according to the above parameters, so as to determine a detection period.
Further exemplary, consider that generally the more loaded a powered device is, the more powered the powered device is. Accordingly, the power supply device 11 may determine the load state of the electric device according to the power level of the electric device in the case of supplying power with the preset voltage. For example, power supply device 11 may obtain the power level of the powered device when power is supplied at a preset voltage (e.g., -48V) for a period of time. And determines the load change rule of the electric equipment 12 according to the obtained content, thereby determining the detection period.
S202, determining a first voltage meeting the requirements of electric equipment according to a dial testing method every interval detection period of the power supply equipment 11.
As illustrated in fig. 3, the power supply device 11 may include a control unit 111 and a voltage output unit 112, for example. Voltage output unit 112 is configured to output a voltage to a powered device to supply power to powered device 12. For example, voltage output unit 112 may rectify an external power source (e.g., 220v,50hz ac) input to the power device, convert the ac power to dc power, and then implement a regulated power output via pulse width modulation (pulse width modulation, PWM) to power powered device 12. The control unit 111 is used for controlling the output voltage of the voltage output unit 112. For example, the control unit 111 may control the duty ratio at which the voltage output unit 112 performs PWM adjustment, thereby controlling the voltage output unit 112 to output a plurality of voltages.
Further, the power supply device 11 may output a plurality of voltages by the voltage output unit 112 according to the dial testing method, respectively, and obtain a test result corresponding to each voltage, respectively, every interval of the detection period. And determining a first voltage meeting the requirements of the electric equipment according to the test result.
In one implementation, taking a detection period as an example, S202 may specifically include:
s2021, the power supply apparatus 11 determines n voltages for dial testing, where n is a positive integer greater than 1.
The n voltages may be n voltages within an operating voltage range of the electric device 12. For example, assuming that the operating voltage range of powered device 12 is-36V to-72V, the n voltages may be n voltages between-36V and-72V. For example, 37 kinds of voltages, i.e., from-36V to-72V, such as-36V, -37V, -38V … -70V, -71V, and-72V, may be selected as the n kinds of voltages with 1V as a step length.
In one possible design, power device 11 may determine the n voltages based on historical power supply records of powered device 12.
Still take the working voltage range of the electric equipment 12 as-36V to-72V as an example, if the power supply voltage of the electric equipment 12 is determined to be kept between-43V and-58V according to the historical power supply record of the electric equipment 12. N voltages for dial testing can be determined from-43V to-58V, while dial testing may not be required for voltages within the interval of-36V to-43V and-58V to-72V.
S2022, the power supply device 11 determines currents corresponding to the electric devices 12 under the n voltages respectively.
Specifically, as in fig. 3, the power supply apparatus 11 further includes a current detection unit 113 therein. The current detecting unit 113 is configured to detect a magnitude of a current flowing through the powered device 12.
As illustrated in fig. 3, the current detection unit 113 specifically includes: a high-precision resistor 1131 connected in series with the powered device in a power supply loop, and a current monitoring chip 1132 connected in parallel with the high-precision resistor 1131. The current monitoring chip 1132 may detect the current flowing through the high-precision resistor 1131, and further determine the current flowing through the powered device 12.
S2023, the power supply device 11 determines the power of the electric device 12 corresponding to the n voltages according to the currents of the electric device 12 corresponding to the n voltages.
Specifically, as shown in fig. 3, after detecting the currents of the electric devices 12 corresponding to the n voltages, the current detection unit 113 may send the detection results to the control unit 111. The control unit 111 calculates the power of the electric device 12 corresponding to the n voltages according to the currents of the electric device 12 corresponding to the n voltages and the voltage values of the n voltages.
S2024, the power supply device 11 determines the first voltage according to the powers of the electric devices 12 corresponding to the n voltages, respectively.
In one possible design, the first voltage may be the voltage at which the power of the corresponding powered device 12 is the smallest of the n voltages.
Illustratively, the power of powered device 12 at each voltage between-36V and-72V calculated by control unit 111 is shown in Table 2 below:
TABLE 2
Supply voltage Output current Power of
-36V 12.4A 449.4W
… … …
-43V 10.4A 447.2W
… … …
-71V 6.6A 468.6W
-72V 6.6A 475.2W
Wherein, for simplicity, the power at several specific voltages is listed in table 2 by way of example only. It can be seen that the power of consumer 12 is at a minimum of-43V, and therefore the first voltage can be determined to be-43V.
It is understood that in other implementations, the first voltage may not belong to one of the n voltages. For example, a change curve of the power of the electric device 12 may be fitted according to the power of the electric device 12 under n voltages, and then the voltage with the smallest power consumption may be determined according to the fitted curve. Fig. 4 is an exemplary graph of powered device 12 at n voltages (i.e., 11 voltages V shown in the graph 1 ～V 11 ) Schematic of the power variation below. Wherein, by fitting the change curve of the power of the electric equipment 12, the voltage with the minimum power of the electric equipment 12 is obtained as V 0 (V 0 Not belonging to one of the n voltages), it can be determined that the first voltage is V 0 。
S203, the power supply device 11 adopts the first voltage as power for supplying power to the electric equipment 12 until the next detection period again determines the voltage for supplying power to the electric equipment 12 according to S202.
In the above embodiment, in each detection period, the power supply device 11 determines the first voltage meeting the requirement of the electric equipment according to the dial testing method, and supplies power to the electric equipment 12 by adopting the first voltage, so as to achieve the effect of reducing energy consumption.
In another embodiment, the voltage with the minimum power corresponding to the powered device 12 in different load states may be determined first, and the corresponding relationship between the different load states and the voltage may be recorded. Then, when the electric equipment 12 is in a certain load state, the voltage corresponding to the load state can be determined directly according to the recorded corresponding relation, and the voltage is used for supplying power to the electric equipment 12, so that the effect of reducing energy consumption is achieved. Specifically, as shown in fig. 5, the method may include:
s301, the power supply device 11 determines, according to a dial testing method, a voltage (hereinafter referred to as a target voltage) with the minimum corresponding power of the electric device 12 in different load states.
For example, the load status of powered device 12 may be reflected as the amount of power of powered device 12 at a preset voltage. In the case of supplying power to the electric device 12 with the preset voltage, if the power of the electric device 12 is greater, the load of the electric device 12 is indicated to be greater. The powered device 12 may be divided into different load states based on the power of the powered device 12 at the preset voltage. The following table 3 is an example:
TABLE 3 Table 3
Supply voltage Power of Load state
-48V [100W,101W) State one
-48V [101W,102W) State two
-48V [102W,103W) State three
… … …
-48V [(x)W,(x+1)W) State x
taking-48V as an example, when the power of the electric equipment 12 under-48V is between 100W and 110W, the load state of the electric equipment 12 is 'state one'; when the power of the electric equipment 12 is between 110W and 120W under the voltage of-48V, the load state of the electric equipment 12 is a state two, and so on.
Then, in the same way as in S202 above, when the electric device 12 is in a certain load state, different voltages are used to supply power to the electric device 12 according to the dial testing method. And then determining the voltage which enables the power of the electric equipment 12 to be minimum according to the detection results corresponding to the different voltages. I.e., the target voltage for which the power of powered device 12 is the smallest in the loaded state is determined.
S302, the power supply device 11 records the correspondence relationship between the load state and the target voltage.
Exemplary, the load state versus voltage correspondence is shown in table 4:
TABLE 4 Table 4
Load state Target voltage
State one 48.5V
State two 44.3V
State three 46.1V
… …
State x 47.3V
Specifically, after the correspondence between the load state and the target voltage is determined, the target voltage corresponding to the current load state of the electric equipment 12 may be determined according to the correspondence, and the electric equipment 12 is powered by using the target voltage. Specifically, as shown in fig. 5, the method may further include:

The process for determining the detection period specifically may refer to S201 above, and will not be described herein.
S304, the power supply device 11 determines the current load state of the electric equipment 12 every interval detection period.
For example, at every detection period, the power supply device 11 supplies power to the electric device 12 with a preset voltage, and determines the power (first power for short) of the electric device 12 at the preset voltage. And then determining the current load state of the electric equipment according to the first power. The current load state of the powered device is determined, for example, by querying the load state corresponding to the first power in table 3 above.
S305, the power supply device 11 determines a target voltage corresponding to the current load state according to the corresponding relationship between the load state and the voltage.
For example, table 4 above, if the current load state of the electric device 12 is the second state, it is determined that the target voltage corresponding to the current load state is 44.3V.
S306, the power supply device 11 adopts the target voltage corresponding to the current load state as power supply to the electric equipment 12 until the next detection period determines the voltage for supplying power to the electric equipment 12 again according to S304-S305.
In the above embodiment, the method provided in this embodiment is described by taking the example that the voltage for supplying power to the powered device 12 is determined once every interval detection period.

For example, power device 11 may monitor the load status of powered device 12 by monitoring the current or power of powered device 12. The larger the current or power of the electric equipment is, the larger the load is indicated under the condition that the voltage is unchanged.
S402, after detecting that the load variation amplitude of the electric equipment 12 exceeds a preset threshold, the power supply equipment 11 determines a target voltage corresponding to the current load state.
In one implementation, referring to the content of S202, the power supply device 11 supplies power to the electric device 12 with different voltages according to the dial testing method. And then determining the voltage which enables the power of the electric equipment 12 to be minimum according to the detection results corresponding to the different voltages. And uses the voltage which minimizes the power consumption of the electric equipment 12 as the target voltage corresponding to the current load state.
In another implementation manner, referring to the content of S305, the target voltage corresponding to the current load state may be determined according to the pre-obtained correspondence between the load state and the voltage.
S403, the power supply device 11 supplies power to the electric equipment 12 by adopting the target voltage corresponding to the current load state until the load change amplitude of the electric equipment 12 is detected to exceed the preset threshold value again, and the voltage for supplying power to the electric equipment is determined again according to the content of S402.
