水位感測器130可設置於儲水槽120中，並可用於在量測儲水槽120內的水位之後，相應地將所測得的水位通知智慧補水裝置110，但可不限於此。The water level sensor 130 may be disposed in the water storage tank 120, and may be used to notify the smart water replenishing device 110 of the measured water level after measuring the water level in the water storage tank 120, but it may not be limited thereto.

如圖1所示，儲水槽120可具有補水管路125，而水泵140可受控於智慧補水裝置110而透過補水管路125將水補入儲水槽120中。另外，智慧補水裝置110可透過用電感測器150監控水泵140的用電量，但可不限於此。As shown in FIG. 1, the water storage tank 120 may have a water supply pipeline 125, and the water pump 140 may be controlled by the smart water supply device 110 to supply water into the water storage tank 120 through the water supply pipeline 125.

請參照圖2，其是依據本發明之一實施例繪示的智慧補水方法流程圖。本實施例的方法可由圖1的智慧補水裝置110執行，以下即搭配圖1所示的元件說明圖2各步驟。Please refer to FIG. 2, which is a flowchart of a smart water supplement method according to an embodiment of the present invention.

首先，在步驟S210中，在用電尖峰時段中，處理器114可透過水位感測器130偵測儲水槽120的第一水位。在步驟S220中，反應於判定第一水位到達儲水槽120的水位下限值，處理器114可取得當下時間點，並依據當下時間點及儲水槽120的用水量模型決定目標水位。在步驟S230中，處理器114可控制儲水槽120的水泵140對儲水槽120補水，直至第一水位到達目標水位。First, in step S210, the processor 114 can detect the first water level of the water storage tank 120 through the water level sensor 130 during the power peak period.

另外，假設儲水槽120的半徑（以r表示）為100公分，水位上限值（以

Figure 02_image037
表示）為477公分，水位下限值（以
Figure 02_image039
表示）為0公分。在此情況下，儲水槽120內的當下儲水量（以s(x)表示）可表徵為第一水位（以x表示）的函數，例如
Figure 02_image041
，但可不限於此。此外，假設水泵140的補水速率（以v表示）為600公升/分鐘，且補水功率（以p表示）為11kW。 In addition, assuming that the radius of the water storage tank 120 (represented by r) is 100 cm, the upper limit of the water level (represented by
Figure 02_image037
Expressed) is 477 cm, and the lower limit of the water level (in
Figure 02_image039
Means) is 0 cm. In this case, the current water storage (represented by s(x)) in the water storage tank 120 can be characterized as a function of the first water level (represented by x), for example
Figure 02_image041
, But not limited to this. In addition, it is assumed that the water supplement rate (represented by v) of the water pump 140 is 600 liters/minute, and the water supplement power (represented by p) is 11 kW.

在圖3中，處理器114可隨時偵測儲水槽120的第一水位。假設處理器114於6/1 13:00偵測到第一水位對應於儲水槽120的水位下限值，則處理器114可取得當下時間點（即，6/1 13:00），並依據當下時間點及儲水槽120的用水量模型決定目標水位（以

Figure 02_image043
表示）。 In FIG. 3, the processor 114 can detect the first water level of the water storage tank 120 at any time. Assuming that the processor 114 detects that the first water level corresponds to the lower limit of the water level of the water storage tank 120 at 6/1 13:00, the processor 114 can obtain the current time point (ie, 6/1 13:00), and base it on The current time point and the water consumption model of the water storage tank 120 determine the target water level (with
Figure 02_image043
Express).

在本實施例中，假設儲水槽120為首次使用，並未有相關的歷史用水量資料及用水量模型。在此情況下，處理器114可以一預設用水量模型300作為儲水槽120的用水量模型，並依據當下時間點及儲水槽120的用水量模型（即，預設用水量模型300）決定目標水位。在其他實施例中，隨著儲水槽120的使用時間增加，處理器114還可收集儲水槽120在各個用電尖峰時段中的用水量資料，從而據以不斷地更新上述用水量模型，但可不限於此。In this embodiment, it is assumed that the water storage tank 120 is used for the first time, and there is no relevant historical water consumption data and water consumption model. In this case, the processor 114 may use a preset water consumption model 300 as the water consumption model of the water storage tank 120, and determine the target according to the current time point and the water consumption model of the water storage tank 120 (ie, the preset water consumption model 300) Water level. In other embodiments, as the use time of the water storage tank 120 increases, the processor 114 may also collect water consumption data of the water storage tank 120 during each peak period of electricity consumption, so as to continuously update the water consumption model mentioned above. Limited to this.

如圖3所示，預設用水量模型300可指示對應於多個用電尖峰時間點（例如7:30~22:30）的多個候選水量（例如15000公升~0公升）。在本實施例中，預設用水量模型300可表徵為w=f 2(x, s(x), t, d)的函數，其中w為候選水量，x為儲水槽120的第一水位，s(x)為儲水槽120的第一水位為x時的水量，t為用電尖峰時段內的時間點，d為日期，但本發明可不限於此。 As shown in FIG. 3, the preset water consumption model 300 may indicate multiple candidate water volumes (for example, 15000 liters to 0 liters) corresponding to multiple peak time points of electricity consumption (for example, 7:30-22:30). In this embodiment, the preset water consumption model 300 can be characterized as a function of w=f 2 (x, s(x), t, d), where w is the candidate water volume, and x is the first water level of the water storage tank 120, s(x) is the water volume when the first water level of the water storage tank 120 is x, t is the time point in the peak period of electricity consumption, and d is the date, but the present invention may not be limited to this.

在此情況下，處理器114可簡易地在預設用水量模型300中找到對應於當下時間點（即，6/1 13:00）的候選水量（例如8000公升），並據以作為目標水量。In this case, the processor 114 can easily find the candidate water volume (for example, 8000 liters) corresponding to the current time point (ie, 6/1 13:00) in the preset water volume model 300, and use it as the target water volume accordingly .

之後，處理器114可再基於此目標水量決定上述目標水位。例如，處理器114可計算

Figure 02_image045
公分，但可不限於此。接著，處理器114可控制儲水槽120的水泵140對儲水槽120補水，直至第一水位到達目標水位（例如254公分）。 After that, the processor 114 may determine the above-mentioned target water level based on the target water volume. For example, the processor 114 may calculate
Figure 02_image045
Centimeters, but not limited to this. Then, the processor 114 may control the water pump 140 of the water storage tank 120 to replenish the water storage tank 120 until the first water level reaches the target water level (for example, 254 cm).

由上可知，本發明的智慧補水裝置110可智慧地決定一目標水位，從而避免在用電尖峰時段中總是無謂地將儲水槽120補水至水位上限值，進而節省水泵140在用電尖峰時段內的耗電量。It can be seen from the above that the smart water replenishment device 110 of the present invention can intelligently determine a target water level, thereby avoiding the needlessly replenishing the water storage tank 120 to the upper limit of the water level during the peak period of electricity consumption, thereby saving the water pump 140 in the peak of electricity consumption. Power consumption during the period.

進一步而言，由以上儲水槽120的相關數據可知，若欲將儲水槽120的第一水位從水位下限值（例如0公分）補至水位上限值（例如477公分），水泵140約需補入15000公升（即

Figure 02_image047
）的水量。換言之，水泵140將儲水槽120的第一水位從水位下限值補至水位上限值所需耗費的第一用電量（以
Figure 02_image049
表示）約為4.58kWh（即，
Figure 02_image051
）。 Furthermore, from the relevant data of the water storage tank 120 above, it can be seen that if the first water level of the water storage tank 120 is to be supplemented from the lower limit of the water level (for example, 0 cm) to the upper limit of the water level (for example, 477 cm), the water pump 140 needs approximately Make up 15,000 liters (ie
Figure 02_image047
) The amount of water. In other words, the water pump 140 replenishes the first water level of the water storage tank 120 from the lower limit of the water level to the upper limit of the water level.
Figure 02_image049
Said) is approximately 4.58kWh (ie,
Figure 02_image051
).

然而，透過本發明所提出的方法，由於水泵140僅將儲水槽120的第一水位從水位下限值（例如0公分）補至上述目標水位（例如254公分），因此水泵140約僅需補入8000公升（即

Figure 02_image053
）的水量。換言之，水泵140將儲水槽120的第一水位從水位下限值補目標水位所需耗費的第二用電量（以
Figure 02_image055
表示）僅約為2.44kWh（即，
Figure 02_image057
）。 However, through the method proposed by the present invention, since the water pump 140 only supplements the first water level of the water storage tank 120 from the lower limit of the water level (for example, 0 cm) to the above-mentioned target water level (for example, 254 cm), the water pump 140 only needs to supplement about Into 8000 liters (ie
Figure 02_image053
) The amount of water. In other words, the water pump 140 changes the first water level of the water storage tank 120 from the lower limit value of the water level to the second power consumption required for the target water level (in terms of
Figure 02_image055
Means) is only about 2.44kWh (ie,
Figure 02_image057
).

因此，第一用電量及第二用電量之間的差異用電量（以

Figure 02_image059
表示）共有2.14kWh（即，
Figure 02_image061
），亦即透過本發明的方法可節省的用電量。 Therefore, the difference between the first electricity consumption and the second electricity consumption (in terms of
Figure 02_image059
Means a total of 2.14kWh (ie,
Figure 02_image061
), that is, the power consumption that can be saved through the method of the present invention.

另外，在現有技術中，水泵在用電離峰時段中的補水策略為在固定時間點即強制將儲水槽補至滿水位。然而，此種作法無法保證在進入用電尖峰時段時儲水槽處於滿水位的狀態，因而可能造成水泵需在用電尖峰時段中進行不必要的補水行為，從而造成額外的耗電。In addition, in the prior art, the water replenishment strategy of the water pump during the ionization peak period is to force the water storage tank to be refilled to the full water level at a fixed time point. However, this approach cannot guarantee that the water storage tank is at a full water level when entering the peak period of power consumption, which may cause the pump to perform unnecessary water replenishment behavior during the peak period of power consumption, resulting in additional power consumption.

有鑑於此，本發明的智慧補水方法另提出在用電離峰時段的補水機制，藉以讓儲水槽120在進入用電尖峰時段時能夠呈現為滿水位的狀態。相關細節詳述如下。In view of this, the smart water replenishment method of the present invention also proposes a water replenishment mechanism during the peak period of ionization, so that the water storage tank 120 can assume a full water level when entering the peak period of power use. The relevant details are detailed below.

請參照圖4，其是依據圖3繪示的用電離峰時段的補水機制示意圖。Please refer to FIG. 4, which is a schematic diagram of the water replenishment mechanism in the ionization peak period shown in FIG. 3.

在本實施例中，假設當下為表2中的用電離峰時段（即，離峰結束時間為7:30），而處理器114可隨時透過水位感測器130偵測儲水槽120的第二水位。之後，處理器114可估計此第二水位與儲水槽120的水位上限值之間的差異水位，並據以決定一差異水量。In this embodiment, it is assumed that the current is the ionization peak period in Table 2 (ie, the off-peak end time is 7:30), and the processor 114 can detect the second time of the water storage tank 120 through the water level sensor 130 at any time. Water level. After that, the processor 114 can estimate the difference water level between the second water level and the upper limit of the water level of the water storage tank 120, and determine a difference water amount accordingly.

以圖4為例，假設所測得的第二水位為200公分，則處理器114可估計此第二水位與水位上限值之間的差異水位為277公分。基此，處理器114可決定對應於上述差異水位的差異水量約為8697.8公升（即

Figure 02_image063
）。亦即，若欲將儲水槽120從第二水位補至水位上限值，水泵140需補入約8697.8公升的水量。 Taking FIG. 4 as an example, assuming that the measured second water level is 200 cm, the processor 114 can estimate that the difference between the second water level and the upper limit of the water level is 277 cm. Based on this, the processor 114 can determine that the amount of differential water corresponding to the above-mentioned differential water level is approximately 8697.8 liters (ie
Figure 02_image063
). That is, if the water storage tank 120 is to be filled from the second water level to the upper limit of the water level, the water pump 140 needs to fill up about 8697.8 liters of water.

之後，處理器114可依據此差異水量及水泵的補水速率（即v）決定一補水時間長度，即將儲水槽120從第二水位補至水位上限值所需的時間長度。承上例，所計算而得的補水時間長度約為14.5分鐘（即8697.8/600）。After that, the processor 114 can determine a replenishment time length, that is, the length of time required for replenishing the water storage tank 120 from the second water level to the upper limit value of the water level, according to the difference water volume and the water replenishment rate (ie v) of the water pump. Continuing the above example, the calculated length of replenishment time is about 14.5 minutes (ie 8697.8/600).

在此情況下，處理器114可控制水泵140於上述離峰結束時間點（即，7:30）前的一指定時間點開始對儲水槽120補水，其中上述指定時間點與離峰結束時間之間的時間差為上述補水時間長度（即，14.5分鐘）。換言之，上述指定時間點即為7:15.5。如此一來，儲水槽120在用電離峰時段結束時可剛好處於滿水位。In this case, the processor 114 may control the water pump 140 to start refilling the water storage tank 120 at a specified time point before the off-peak end time point (ie, 7:30), wherein the specified time point and the off-peak end time The time difference between is the above-mentioned length of rehydration time (i.e., 14.5 minutes). In other words, the above specified time point is 7:15.5. In this way, the water storage tank 120 can be just at the full water level at the end of the ionization peak period.

在其他實施例中，若處理器114後續偵測到第二水位出變化，仍可基於上述教示而估計新的指定時間點，進而讓儲水槽120在用電離峰時段結束時可剛好處於滿水位。In other embodiments, if the processor 114 subsequently detects a change in the second water level, it can still estimate a new specified time point based on the above teachings, so that the water storage tank 120 can be just at the full water level at the end of the ionization peak period. .

從另一觀點而言，本發明的方法可理解為將本來需在用電尖峰時段中耗費的部分電量（即，上述差異用電量）移轉至用電離峰時段，進而可相應地節省相關的用電費用。From another point of view, the method of the present invention can be understood as transferring part of the electricity that was originally consumed during the peak period of electricity consumption (ie, the above-mentioned differential electricity consumption) to the peak period of ionization, thereby saving relevant Electricity costs.

以圖3及圖4情境為例，本發明的方法可理解為將47%（即2.14/4.58）的用電量移轉至用電離峰時段。依表1及表2的內容可知，圖3的用電尖峰時段的第一電價為4.67，圖4的用電離峰時段的第二電價為1.32，因此處理器114可在估計第一電價及第二電價之間的差異費率（即，3.35）之後，基於此差異費率及上述差異用電量（即，2.14kWh）估計一補水用電節費，即本發明的作法可節省的電費。例如，處理器114可估計上述補水用電節費為7.169元（即，3.35x2.14）。亦即，本發明的方法共可節省72%（即，(4.67-1.32)/4.67）的電費。Taking the scenarios of Figure 3 and Figure 4 as an example, the method of the present invention can be understood as shifting 47% (ie 2.14/4.58) of the electricity consumption to the peak period of ionization. According to the contents of Table 1 and Table 2, the first electricity price in the peak period of electricity consumption in FIG. 3 is 4.67, and the second electricity price in the peak ionization period of FIG. 4 is 1.32. Therefore, the processor 114 can estimate the first electricity price and the first electricity price. After the difference rate between the two electricity prices (ie, 3.35), based on this difference rate and the above-mentioned difference in electricity consumption (ie, 2.14kWh), estimate a water and electricity saving fee, that is, the electricity fee that can be saved by the method of the present invention. For example, the processor 114 may estimate that the above-mentioned water and electricity saving cost is 7.169 yuan (ie, 3.35×2.14). That is, the method of the present invention can save 72% (ie, (4.67-1.32)/4.67) of electricity bills in total.

在一些實施例中，處理器114例如可基於迴歸分析法、類神經網路等技術而動態學習/更新儲水槽120的用水量模型（即，w=f 2(x, s(x), t, d)）。舉例而言，假設處理器114於6/1~9/30每日7:30~22:30所收集而得的用水量資料如下表3。 時間 用水量（公升） 儲水槽內水量 08:30 1200 14300 09:30 1300 13000 10:30 800 12200 11:30 500 11700 12:30 1500 10200 13:30 1300 8900 14:30 200 8700 15:30 300 8400 16:30 400 8000 17:30 800 7200 18:30 1800 5400 19:30 1600 3800 20:30 1500 2300 21:30 1000 1300 22:30 800 50 23:30 500 0 表3 In some embodiments, the processor 114 may dynamically learn/update the water consumption model of the water storage tank 120 based on techniques such as regression analysis and neural network (ie, w=f 2 (x, s(x), t) , d)). For example, suppose that the water consumption data collected by the processor 114 from 7:30 to 22:30 daily from 6/1 to 9/30 are shown in Table 3 below. time Water consumption (liter) Water volume in water storage tank 08:30 1200 14,300 09:30 1300 13000 10:30 800 12200 11:30 500 11700 12:30 1500 10200 13:30 1300 8900 14:30 200 8700 15:30 300 8400 16:30 400 8000 17:30 800 7200 18:30 1800 5400 19:30 1600 3800 20:30 1500 2300 21:30 1000 1300 22:30 800 50 23:30 500 0 table 3

相應地，處理器114可據以更新儲水槽120的用水量模型。請參照圖5，其是依據圖3繪示的用電尖峰時段的補水機制示意圖。在本實施例中，假設儲水槽120的用水量模型500經更新/學習後具有圖5所示態樣。在此情況下，假設處理器114於13:00偵測到第一水位到達儲水槽120的水位下限值，則處理器114可取得當下時間點（即，13:00），並依據當下時間點及儲水槽120的用水量模型決定目標水位（

Figure 02_image043
）。 Correspondingly, the processor 114 can update the water consumption model of the water storage tank 120 accordingly. Please refer to FIG. 5, which is a schematic diagram of the water replenishment mechanism in the peak period of electricity consumption shown in FIG. 3. In this embodiment, it is assumed that the water consumption model 500 of the water storage tank 120 has the state shown in FIG. 5 after being updated/learned. In this case, assuming that the processor 114 detects that the first water level reaches the lower limit of the water level of the water storage tank 120 at 13:00, the processor 114 can obtain the current time point (that is, 13:00) and base it on the current time The water consumption model of point and storage tank 120 determines the target water level (
Figure 02_image043
).

在圖5中，處理器114可簡易地在預設用水量模型500中找到對應於當下時間點（即，13:00）的候選水量（例如9550公升），並據以作為目標水量。In FIG. 5, the processor 114 can easily find the candidate water volume (for example, 9550 liters) corresponding to the current time point (ie, 13:00) in the preset water volume model 500, and use it as the target water volume accordingly.

之後，處理器114可再基於此目標水量決定上述目標水位。例如，處理器114可計算

Figure 02_image065
公分，但可不限於此。接著，處理器114可控制儲水槽120的水泵140對儲水槽120補水，直至第一水位到達目標水位（例如304公分）。 由上可知，本發明的智慧補水裝置110可依據儲水槽120的用水量資料智慧地決定目標水位，從而避免在用電尖峰時段中總是無謂地將儲水槽120補水至水位上限值，進而節省水泵140在用電尖峰時段內的耗電量。 After that, the processor 114 may determine the above-mentioned target water level based on the target water volume. For example, the processor 114 may calculate
Figure 02_image065
Centimeters, but not limited to this. Then, the processor 114 may control the water pump 140 of the water storage tank 120 to replenish the water storage tank 120 until the first water level reaches the target water level (for example, 304 cm). It can be seen from the above that the smart water replenishment device 110 of the present invention can intelligently determine the target water level according to the water consumption data of the water storage tank 120, thereby avoiding the needlessly replenishing the water storage tank 120 to the upper limit of the water level during the peak period of electricity consumption. The power consumption of the water pump 140 during the peak period of power consumption is saved.
