Moreover, the Ethernet power supply device has a target total power consumption. When the long-term total power consumption is greater than the target total power consumption, the long-term total power consumption is subtracted from the target total power consumption to generate an energy-saving electricity. Quantity, the Ethernet power supply unit calculates the daily daily electricity consumption based on the saved electricity consumption. When the low power consumption period with the lowest power consumption during the day is used, the number of low priority power receiving devices is determined according to the daily power consumption.

In addition, the present invention also provides an Ethernet power management method, including the following steps, first recording the power consumption of a plurality of power receiving devices for a long time, and calculating the power consumption of the plurality of power receiving devices to generate a long-term total power consumption; In the plurality of power receiving devices, at least part of the power receiving device is defined as a low priority power receiving device, and a target total power consumption is set, and according to the long-term recorded power consumption of the power receiving device, the time period during which the power consumption is the lowest is defined as a low time. When the long-term total power consumption is greater than the target total power consumption, the long-term total power consumption is subtracted from the target total power consumption, and a power saving is generated, and each power consumption is calculated. Daily daily electricity consumption; during low power consumption period, the number of low-priority power-receiving devices is turned off according to the daily power consumption; and the power supply to the low-priority power receiving device is restored during the non-low power consumption period.

In addition to being defined as the period of the lowest power consumption in a day, the present invention can also determine the daily power consumption according to the long-term recording of the power consumption of the plurality of power receiving devices, so as to be divided according to the periods of low, medium, and high power consumption. The low power consumption period, the medium power consumption period, and the high power consumption period avoid the sum of the power consumption of the plurality of low priority devices that are turned off during the low power consumption period, and are less than the daily power consumption, and may continue during the medium power consumption period.

The third figure is a flow chart of steps of another embodiment of the present invention.

Please refer to the first figure, which is a block diagram of the system of the present invention, including a computer device 10 electrically connected to an Ethernet power supply device 12, and the Ethernet power supply device 12 is electrically connected. The power receiving device 14 is configured to supply power to the plurality of power receiving devices 14 and record the power consumption of the plurality of power receiving devices 14 at each time, and record in a manner of day, month, and year. The power receiving device 14 can be a computer, a server, or the like. Internet phone, wireless base station, webcam or hub. The computer device 10 can provide a target total power consumption for the user in the Ethernet power supply device 12. The computer device 10 can determine the power usage during the day according to the power consumption recorded by the Ethernet power supply device 12. The quantity is determined as a period of low, medium, and high power consumption in a day, and the three periods are respectively divided into a low power consumption period, a medium power consumption period, and a high power consumption period. The computer device 10 can also set at least part of the power receiving device 14 as the low priority power receiving device 142, and notify the partial power receiving device 14 of the Ethernet power supply device 12 as the low priority power receiving device 142, wherein the low priority power receiving device 142 It is a power receiving device 14 that is not commonly used, or a power receiving device 14 that uses a low power amount, and the low priority power receiving device 142 can also be set by the user. Therefore, the Ethernet power supply device 12 records each of the plurality of power receiving devices 14 at each moment. After the long-term total power consumption is greater than the target total power consumption, the Ethernet power supply unit 12 subtracts the long-term total power consumption from the target total power consumption. A power saving is generated, and the daily daily power consumption is calculated according to the saved power consumption, and the number of the plurality of low priority power receiving devices 142 is determined according to the daily saving power consumption. The order in which the number of the plurality of low priority power receiving devices 142 is turned off to turn off the low priority power receiving device 142 is explained in detail below.

Referring to the first figure and the second figure, a flow chart of the steps of how to control the power consumption of the present invention will be described in detail. As shown in the figure, first, the process proceeds to step S10, and the Ethernet power supply device 12 can record the plural for a long time. The power consumption of the power receiving device 14 records the power consumption of the power receiving device 14 at each time. Therefore, the Ethernet power supply device 12 can calculate the total power consumption of all the plurality of power receiving devices 14 according to the previous record, thereby generating a long-term total power consumption. The amount of power recorded in the present embodiment is 30 days, so the total long-term total power consumption is the power consumption used by all the power receiving devices 14 for 30 days. Next, proceeding to step S12, at least part of the power receiving device 14 is defined as a low priority power receiving device 142 by the computer device 10, and the power receiving device 14 of the low priority power receiving device 142 is notified that the Ethernet power feeding device 12 is the low priority power receiving device 142. For which of the power receiving devices 14, the computer device 10 can set a target total power consumption for the Ethernet power supply device 12, and judge the power consumption of the power receiving device 14 recorded by the Ethernet power supply device 12 for a long time. The time period in which the average electric power is the lowest in the day is determined as a low power consumption period. Then, proceeding to step S14, when the long-term total power consumption is greater than the target total power consumption, the long-term total power consumption is subtracted from the target total power consumption, and a power saving is generated, and the power consumption is calculated according to the saved power consumption. Daily daily savings in electricity usage. Then, the process proceeds to step S16. During the low power consumption period, the Ethernet power supply device 12 is the root. According to the daily saving power consumption, the number of the plurality of low priority power receiving devices 142 is turned off, so that the sum of the power consumption of the closed plurality of low priority devices is greater than or equal to the daily saving power consumption; finally, the process proceeds to step S18, leaving low. During the power usage period, power is supplied to the low priority power receiving device 142 during the non-low power usage period.

If the above embodiment is exemplified by a practical example, in step S10, based on the previous record, it is assumed that the long-term total power consumption of all the power receiving devices 14 recorded for 30 days is 86,400 watts, and then the process proceeds to step S12, and the low priority is set. The number of power receiving devices 142 is six low priority power receiving devices 142, and the user sets the target total power consumption for this month to 80000 watts, and judges 0:00~ according to the record of the Ethernet power supply device 12. 8:00 is the period with the lowest power consumption, so setting 0:00~8:00 is the low power consumption period. Then, when proceeding to step S14, since the total long-term total power consumption is 86,400 watts and the total target power consumption is 80,000 watts, the long-term total power consumption is greater than the target total power consumption, so the long-term total power consumption and the target total are used. The power consumption is reduced, that is, 86400 watts - 80,000 watts = 6,400 watts, resulting in a saving of 6400 watts of electricity, and then the daily electricity consumption is calculated based on the average number of days. This embodiment takes 30 days as an example, that is, 6400. ÷ 30 days, about 314 watts a day, so that you need to save at least 314 watts of electricity per day. Then, proceeding to step S16, the low-priority power receiving device 142 is automatically turned off during the low power consumption period from 0:00 to 8:00, thereby saving 8 hours and 6 sets of 6 watts of power, that is, saving 6 watts x 6 sets of x8 Hour = 288 watts, wherein the order in which the low priority power receiving device 142 is turned off can be set by the user to set the shutdown order. In addition, the low priority power receiving device 142 may also be a different power receiving device 14, which may be worn out. Since the electric energy is different, if the low priority power receiving device 142 is different from the power receiving device 14, and the user does not set the low priority power receiving device 142, the order of turning off the low priority power receiving device 142 can be based on the power consumption. Sorting, low priority power receiving device 142 with less power consumption First turned off. Finally, the process proceeds to step S18, and when the low power consumption period is left, that is, after the time point of 0:00 to 8:00, the power supply to the low priority power receiving device 142 is restored.

Referring to the first and third figures, in addition to the above embodiments, the invention can divide the day into a low power consumption period, a medium power consumption period, and a high power consumption period, and the method for managing the power consumption in detail will be As detailed below. First, the process proceeds to step S30. The Ethernet power supply device 12 can record the power consumption of the plurality of power receiving devices 14 for a long time, and record the power consumption of the power receiving device 14 at each time. Therefore, the Ethernet power supply device 12 can calculate according to the previous record. The total power consumption of all the plurality of power receiving devices 14 generates a long-term total power consumption. The time recorded in the example of the embodiment is 30 days, so the long-term total power consumption is 30 days for all the power receiving devices 14 used. the amount. Next, proceeding to step S32, at least part of the power receiving apparatus 14 is defined as a low priority power receiving apparatus 142 by the computer device 10, and the power receiving apparatus 14 of the low priority power receiving apparatus 142 is notified that the Ethernet power feeding apparatus 12 is the low priority power receiving apparatus 142. For which power receiving device 14, the computer device 10 can set a target total power consumption for the Ethernet power supply device 12, and the computer device 10 divides the day into three time periods, each time period is eight hours, and according to The long-term recorded power consumption of the power receiving device 14 determines the time period during which the power consumption in the day is low, medium, and high, and divides the three time periods into a low power consumption period, a medium power consumption period, and a high power consumption period. Next, proceeding to step S34, when the long-term total power consumption is greater than the target total power consumption, the Ethernet power supply device 12 reduces the total long-term total power consumption and the target total power consumption, thereby generating a saved power consumption. The daily daily electricity consumption is calculated based on the saved electricity consumption. Next, proceeding to step S36, in the low power consumption period, the number of the plurality of low priority power receiving devices 142 is determined according to the daily power saving, and the previously set low priority power receiving device 142 is determined to be turned off during the low power consumption period. The sum of the power consumption of the plurality of low priority devices 142, Whether it is less than the daily saving power consumption; if not, that is, the sum of the power consumption of the plurality of low priority devices 142 exceeds or equals the daily saving power consumption, then the process proceeds to step S38, and the power supply is returned to the low priority during the non-low power consumption period. If the sum of the power consumption of the plurality of low priority devices 142 is less than the daily power consumption, the process proceeds to step S40 to continuously turn off the plurality of low priority devices during the medium power consumption period. Finally, the process proceeds to step S42, and the power supply to the low priority power receiving device 142 is resumed during the non-low power consumption period and the non-medium low power consumption period, that is, the high power consumption period.

If the above embodiment is exemplified by a practical example, the process proceeds to step S30. The Ethernet power supply device 12 can record the power consumption of the plurality of power receiving devices 14 for a long period of time, and generate a long-term total power consumption. The time is 30 days, so the long-term total electricity consumption is the electricity used by all the power receiving devices 14 for 30 days, and the long-term total electricity consumption is 86,400 watts. Next, proceeding to step S32, at least four power receiving devices 14 are defined as the low priority power receiving device 142 through the computer device 10, and the computer device 10 can set a target total power consumption for the Ethernet power supply device 12. The amount is 80,000 watts, and the computer device 10 determines the time during which the power consumption in the day is low, medium, and high according to the power consumption of the power receiving device 14 recorded for a long period of time, and determines that the power is set to be low from 0:00 to 8:00. During the time period, 16:00-0:00 is set to the medium power consumption period, and 8:00-16:00 is set as the high power consumption period. Next, proceeding to step S34, since the total long-term total power consumption is 86,400 watts and the total target power consumption is 80,000 watts, the long-term total power consumption is greater than the target total power consumption, so the long-term total power consumption and the target total are used. The power consumption is reduced, that is, 86,400 watts - 80,000 watts = 6,400 watts, resulting in a saving of 6400 watts of power, and then the daily electricity consumption is calculated based on the average number of days. This embodiment is calculated by taking 30 days a month as an example, that is, 6400 ÷ 30 days, about 314 watts a day, resulting in a daily savings of at least 314 watts of electricity. Then proceeding to step S36, The four low priority power receiving devices 142 are automatically turned off during the low power consumption period. If one low priority power receiving device 142 is used, it takes 6 watt hours, so when the four low priority power receiving devices 142 are turned off during the low power consumption period, only Can save 6 watts x 4 sets x 8 hours = 192 watts, which is less than the daily saving power consumption of 314 watts, which means the sum of the power consumption of the plurality of low priority devices 142 that are turned off during the low power consumption period, which is insufficient to save electricity daily. The quantity is in the low power consumption period, so the process proceeds to step S40, and the four units are continuously turned off during the middle power consumption period, that is, 6 watts x 4 units x 16 hours = 384 watts, which is greater than the daily saving power consumption of 314 watts, thereby achieving power saving. For the purpose, the order in which the low priority power receiving device 142 is turned off can be set by the user to set the order of closing. In addition, the low-priority power receiving device 142 may also be different power receiving devices 14, and the power consumption may be different. Therefore, if the low-priority power receiving device 142 is a different power receiving device 14, the user does not make the shutdown sequence. At the time of setting, the order of turning off the low priority power receiving device 142 can be sorted according to the power consumption, and the low priority power receiving device 142 having the lower power consumption is first turned off. Finally, the process proceeds to step S42, and the power supply to the low priority power receiving device 142 is resumed during the non-low power consumption period and the non-medium low power consumption period, that is, the high power consumption period.

If it is determined in step S36 that the sum of the power consumptions of the plurality of low priority devices 142 exceeds or equals the daily power consumption, the process proceeds to step S38, indicating that the saving can be completed only in the low power consumption period, and then proceeds to step S38. The non-low power consumption period, that is, the medium power consumption period and the high power consumption period, is restored to the low priority power receiving device 142, and the actual implementation thereof is the same as that of the first embodiment described above, and thus the description will not be repeated.

In summary, the present invention can record the power consumption of the power receiving device, and record the data in the manner of day, month, and year. In addition, the Ethernet power supply device can define a power target to The power consumption of the target control tube can effectively control the cost of electricity consumption.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Therefore, any changes or modifications of the features and spirits of the present invention should be included in the scope of the present invention.
