The details are described below.

請參照圖2，其是依據本發明之一實施例繪示的路燈迴路異常分析方法流程圖。本實施例的方法可由圖1的路燈迴路異常分析裝置110執行，以下即搭配圖1所示的元件說明圖2各步驟的細節。Please refer to FIG. 2, which is a flowchart of a method for analyzing an abnormality of a street lamp circuit according to an embodiment of the present invention. The method of this embodiment can be executed by the street lamp circuit abnormality analysis device 110 in FIG. 1. The details of each step in FIG. 2 are described below with the components shown in FIG. 1.

首先，在步驟S210中，處理器114可收集路燈迴路120的多個用電資料。如先前所述的，監控單元131~13M可定期或不定期地自動回報路燈121~12M的用電資料，或是由處理器114要求監控單元131~13M相關的用電資料，但本發明可不限於此。First, in step S210, the processor 114 may collect a plurality of electricity consumption data of the street light circuit 120. As mentioned earlier, the monitoring units 131~13M can automatically report the electricity consumption data of the street lights 121~12M regularly or irregularly, or the processor 114 can request the monitoring units 131~13M related electricity consumption data, but the present invention may not Limited to this.

在步驟S220中，處理器114可取得查詢時間區間、門檻基準區間及誤差百分比。在一實施例中，處理器114可透過使用者界面（例如是路燈迴路異常分析裝置110上的輸入界面）接收使用者輸入的查詢時間區間、門檻基準區間及誤差百分比。In step S220, the processor 114 may obtain the query time interval, the threshold reference interval, and the error percentage. In one embodiment, the processor 114 may receive the query time interval, threshold reference interval, and error percentage input by the user through a user interface (for example, an input interface on the street lamp loop abnormality analysis device 110).

在一實施例中，假設使用者欲查詢某個時間區間的路燈迴路120的用電需量是否正常，使用者即可將此時間區間作為查詢時間區間而輸入至路燈迴路異常分析裝置110。舉例而言，若使用者欲監測本日0時的路燈迴路120的情形，則使用者可以「今日0時0分」作於查詢時間區間而輸入至路燈迴路異常分析裝置110。在不同的實施例中，上述查詢時間區間可以15分鐘為一個單位，以讓使用者輸入每小時的0、15、30、45分來進行查詢，但可不限於此。In one embodiment, suppose the user wants to query whether the electricity demand of the street light circuit 120 in a certain time interval is normal, the user can input the time interval as the query time interval to the street light circuit abnormality analysis device 110. For example, if the user wants to monitor the situation of the street light circuit 120 at 0 o'clock of the day, the user can enter the street light circuit abnormality analysis device 110 in the query time interval "today 0: 0 o'clock". In different embodiments, the aforementioned query time interval may be 15 minutes as a unit, so that the user can input 0, 15, 30, and 45 minutes per hour for query, but it is not limited to this.

此外，由於用於對路燈迴路120供電的電力公司可能會在一天之中的某些時段（例如06:40至18:50等）不對路燈迴路120進行供電（下稱未供電時段），因此若使用者輸入的查詢時間區間屬於未供電時段，則處理器114例如可透過上述使用者界面向使用者提供一查詢錯誤訊息，並要求使用者再次輸入查詢時間區間。In addition, since the power company used to supply power to the street light circuit 120 may not supply power to the street light circuit 120 during certain periods of the day (for example, 06:40 to 18:50, etc.) (hereinafter referred to as the non-powered period), if If the query time interval entered by the user belongs to the period of no power supply, the processor 114 may provide the user with a query error message through the aforementioned user interface, and request the user to enter the query time interval again.

在一實施例中，上述門檻基準區間例如是由使用者輸入的一特定天數。舉例而言，若使用者輸入10天來作為上述門檻基準區間，則路燈迴路異常分析裝置110可相應地將查詢時間區間所對應的查詢日期的前、後10天的相關用電資料找出，以作為後續進行判斷的依據。在其他實施例中，使用者亦可在1、2、3、7、15、30中擇一作為上述門檻基準區間，但本發明可不限於此。In one embodiment, the threshold reference interval is, for example, a specific number of days input by the user. For example, if the user enters 10 days as the threshold reference interval, the street lamp circuit abnormality analysis device 110 can correspondingly find out the relevant electricity consumption data of the 10 days before and after the inquiry date corresponding to the inquiry time interval. As a basis for subsequent judgments. In other embodiments, the user can also select one of 1, 2, 3, 7, 15, and 30 as the threshold reference interval, but the present invention is not limited to this.

在一實施例中，上述誤差百分比可由使用者透過使用者界面輸入，或是由路燈迴路異常分析裝置110基於一或多個預設值來設定，但本發明可不限於此。In one embodiment, the above-mentioned error percentage may be input by the user through the user interface, or set by the street lamp loop abnormality analysis device 110 based on one or more preset values, but the invention is not limited to this.

之後，在步驟S230中，處理器114可依據查詢時間區間及門檻基準區間在用電資料中找出多個待分析用電資料。在一實施例中，處理器114可取得查詢時間區間所屬的查詢日期。舉例而言，假設使用者輸入的查詢時間區間為5月20日的下午5點，則此查詢時間區間所屬的查詢日期即為5月20日。After that, in step S230, the processor 114 may find a plurality of electricity consumption data to be analyzed in the electricity consumption data according to the query time interval and the threshold reference interval. In an embodiment, the processor 114 may obtain the query date to which the query time interval belongs. For example, if the query time interval entered by the user is 5 pm on May 20, the query date to which this query time interval belongs is May 20.

接著，處理器114可取得與查詢日期相距門檻基準區間以內的多個目標日期。承上例，若門檻基準區間為n，則在查詢日期為5月20日的情況下，處理器114可取得5月20日的前、後n日作為目標日期。舉例而言，若n為10，則處理器114可取得5月10日至5月19日（即，5月20日的前10日），以及5月21日至5月30日（即，5月20日的後10日）等日期作為目標日期。Then, the processor 114 can obtain multiple target dates within the threshold reference interval from the query date. Continuing the above example, if the threshold reference interval is n, if the query date is May 20, the processor 114 can obtain the n days before and after May 20 as the target date. For example, if n is 10, the processor 114 can obtain May 10 to May 19 (that is, the first 10 days of May 20), and May 21 to May 30 (that is, 10 days after May 20) as the target date.

之後，處理器114可依據查詢時間區間在各目標日期中取得目標時段，其中各目標日期的該目標時段對應於查詢時間區間。承上例，在查詢時間區間為5月20日的下午5點的情況下，處理器114可將5月10日至5月19日，以及5月21日至5月30日等各日中的下午5點作為目標時段（在此例中共有20個目標時段）。After that, the processor 114 may obtain the target time period in each target date according to the query time interval, wherein the target time period of each target date corresponds to the query time interval. Continuing the above example, if the query time interval is 5 pm on May 20th, the processor 114 can convert the period from May 10th to May 19th, and from May 21st to May 30th. 5:00 pm as the target period (in this example, there are 20 target periods).

繼之，處理器114可在前述用電資料中找出對應於查詢時間區間及各目標日期的目標時段的一部分作為前述待分析用電資料。再承上例，處理器114可將5月10日至5月30日中每日下午5點的用電資料作為待分析用電資料，但本發明可不限於此。Subsequently, the processor 114 can find a part of the target period corresponding to the query time interval and each target date in the aforementioned electricity consumption data as the aforementioned electricity consumption data to be analyzed. Continuing the above example, the processor 114 may use the electricity consumption data at 5 pm every day from May 10 to May 30 as the electricity consumption data to be analyzed, but the present invention is not limited to this.

在取得待分析用電資料之後，在步驟S240中，處理器114可基於待分析用電資料及誤差百分比定義用電需量範圍。在一實施例中，處理器114可經配置以：計算統計天數值；計算對應於統計天數值的平均用電量；計算用電需量範圍的上限值；及計算用電需量範圍的下限值。After obtaining the power consumption data to be analyzed, in step S240, the processor 114 may define the power demand range based on the power consumption data to be analyzed and the error percentage. In an embodiment, the processor 114 may be configured to: calculate the statistical day value; calculate the average power consumption corresponding to the statistical day value; calculate the upper limit of the power demand range; and calculate the power demand range lower limit.

在不同的實施例中，統計天數值可表徵為

及
Figure 02_image017
之間的範圍。In different embodiments, the statistical day value can be characterized as
Figure 02_image001
, Where N is the number of statistical days and n is the threshold reference interval. In addition, the average power consumption can be characterized as:

,among them
Figure 02_image005
Is the average electricity consumption,
Figure 02_image007
It is the i-th to-be-analyzed power-use data among the above-mentioned power-use data to be analyzed. The upper limit of the power demand range can be characterized as:

Is the error percentage. The lower limit of the power demand range can be characterized as:
Figure 02_image015
, Where Num is the number of street lamps 121-12M in the street lamp circuit 120. Based on this, the range of electricity demand can be defined as between
Figure 02_image011
and
Figure 02_image017
The range between.

之後，在步驟S250中，處理器114可從待分析用電資料中找出對應於查詢時間區間的用電需量，並在步驟S260中判斷用電需量是否超出用電需量範圍。承上例，在查詢時間區間為5月20日的下午5點的情況下，處理器114可取出5月20日的下午5點的用電需量，並判斷此用電需量是否超出用電需量範圍。亦即，處理器114可判斷此用電需量是否介於

Figure 02_image011
及
Figure 02_image017
。若否，即代表此用電需量超出用電需量範圍，反之則未超出用電需量範圍。After that, in step S250, the processor 114 can find the power demand corresponding to the query time interval from the power data to be analyzed, and determine whether the power demand exceeds the power demand range in step S260. Continuing from the above example, when the query time interval is 5 pm on May 20, the processor 114 can retrieve the electricity demand at 5 pm on May 20, and determine whether this electricity demand exceeds the demand. Electricity demand range. That is, the processor 114 can determine whether the power demand is between
Figure 02_image011
and
Figure 02_image017
. If not, it means that the electricity demand exceeds the electricity demand range, otherwise, it does not exceed the electricity demand range.

在一實施例中，若用電需量超出用電需量範圍，則處理器114可執行步驟S270以產生路燈迴路120的迴路異常警示，反之則可執行步驟S280，以判定用電需量為正常。In one embodiment, if the power demand exceeds the power demand range, the processor 114 may perform step S270 to generate a loop abnormality warning of the street light circuit 120, otherwise, it may perform step S280 to determine that the power demand is normal.

綜上所述，本發明提出的路燈迴路異常分析方法及裝置可利用ICT技術收集路燈迴路用電資料，再進行門檻基準、統計天數及誤差百分比設定及資料分析手段，查測路燈迴路使用狀況，從而達到快速評估路燈迴路用電需量是否合理，以及判斷是否需立即進行維護作業。藉此，可讓使用者在維護管理路燈迴路時，能更方便、更快速地發現迴路異常情形，以減少路燈失常時間、提升管理效率並降低維護人力成本。In summary, the street lamp circuit abnormality analysis method and device proposed in the present invention can use ICT technology to collect street lamp circuit electricity consumption data, and then perform threshold benchmarks, statistical days and error percentage settings and data analysis methods to check the use of street lamp circuits.
