Description
本发明涉及能耗监测诊断方法，特别涉及一种非运行时段建筑照明插座支路用能诊断方法。The invention relates to a method for monitoring and diagnosing energy consumption, in particular to a method for diagnosing the energy consumption of a branch circuit of a lighting socket in a non-operation period.
目前大数据挖掘、物联网等技术在建筑行业应用最广泛的就是能耗监测平台，仅上海就已建成约2000幢建筑能耗监测平台。能耗监测平台数据可以为政府能耗决策、能耗限额标准编制等提供大量的数据支撑，但是在建筑实际运行过程中，由于管理人员的专业知识局限性，同时缺少一种能够有效联系监测数据与用能设备之间的渠道，无法及时利用大量数据分析用能设备的运行情况，从而导致了一些由于用能设备问题引发的能源浪费。At present, the most widely used technologies such as big data mining and Internet of Things in the construction industry are energy consumption monitoring platforms. In Shanghai alone, about 2,000 building energy consumption monitoring platforms have been built. The energy consumption monitoring platform data can provide a large amount of data support for government energy consumption decision-making and the compilation of energy consumption quota standards. However, in the actual operation of the building, due to the limitation of the professional knowledge of the management personnel, there is a lack of a way to effectively contact the monitoring data The channel between the energy-using equipment and the energy-using equipment cannot use a large amount of data to analyze the operation of the energy-using equipment in time, resulting in some energy waste caused by the problems of the energy-using equipment.
建筑照明插座用能一直是行业内研究的热点和难点，相关文献显示运行时段照明插座节能控制技术、照明插座回路系统节能设计及照明插座用能模式等研究是目前研究的重点方向，而对非运行时段的建筑照明插座用能研究则甚少，因此应加强非运行时段的建筑照明插座用能方面的研究，以期通过研究分析，减少非运行时段建筑照明插座用电存在的用能浪费。The energy consumption of architectural lighting sockets has always been a hot and difficult point of research in the industry. Relevant literature shows that the energy-saving control technology of lighting sockets during operating hours, the energy-saving design of lighting socket loop systems, and the energy consumption mode of lighting sockets are the key directions of current research. There is very little research on the energy consumption of architectural lighting sockets during operating periods. Therefore, research on the energy consumption of architectural lighting sockets during non-operating periods should be strengthened in order to reduce energy waste in non-operating periods of building lighting sockets through research and analysis.

以下结合附图对本发明作进一步详细说明。Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings.
根据一个或多个实施例，公开的一种非运行时段建筑照明插座支路用能诊断方法，如图1所示，具体包括以下步骤：According to one or more embodiments, a disclosed method for diagnosing the energy consumption of a branch of a building lighting socket during a non-operation period, as shown in FIG. 1, specifically includes the following steps:
步骤A：识别进行非运行时段照明插座支路用能诊断的照明插座支路所在建筑类型。本发明针对的建筑类型主要包括办公建筑、商场建筑具有明显运行与非运行时段的建筑，不包括医疗卫生建筑、宾馆饭店建筑全年无休建筑。Step A: Identify the type of building where the lighting socket branch is located for the energy use diagnosis of the lighting socket branch during the non-operation period. The building types targeted by the present invention mainly include office buildings and shopping mall buildings that have obvious operating and non-operating periods, and do not include medical and health buildings, hotels and restaurant buildings all year round.
步骤B：通过能耗监测平台数据，识别建筑照明插座支路开始运行时点和停止运行时点。通过建筑照明插座支路用电波峰波谷变化判定照明插座开始和停止运行时点，将采集的当前用电数据与前一时点的用电数据进行对比，根据设定的第一比例和第二比例识别开始和停止的运行时点。Step B: Through the energy consumption monitoring platform data, identify the starting point of the building lighting socket branch and the point of stopping the operation. Determine the start and stop time of the lighting socket by the change of the electric wave peak and valley of the architectural lighting socket branch, and compare the collected current power consumption data with the power consumption data at the previous point in time, according to the set first and second ratios Identify the start and stop operating time points.
照明插座支路开始运行时点的识别为：照明插座支路用电后一时点采集用电数据若高于前一时点采集用电数据的第一比例，即50％，则判定照明插座此时已经开始运行。如照明插座前一时点采集用电数据为1.5kWh，后一时点运行采集数据为4.5kWh，前后变化200％，因此可认定此时照明插座支路开始运行。The identification of the time when the lighting socket branch starts to operate is: if the electricity consumption data collected at the time after the lighting socket branch uses electricity is higher than the first proportion of the electricity consumption data collected at the previous time point, that is, 50%, it is determined that the lighting socket is at this time It has started running. For example, the electricity consumption data collected at the previous point in time for the lighting socket was 1.5kWh, and the data collected at the next point in time was 4.5kWh, with a change of 200% before and after. Therefore, it can be determined that the lighting socket branch is running at this time.
照明插座支路停止运行时点的识别为：照明插座支路用电后一时点采集用电数据若低于前一时点采集用电数据的第二比例，同样设置为50％，则判定照明插座支路此时已经停止运行。如照明插座支路前一时点采集用电数据为4.0kWh，后一时点运行采集用电数据为0.9kWh，前后变化77％，因此可认定此时照明插座支路停止运行。The identification of the point when the lighting socket branch stops running is: if the electricity consumption data collected at a point in time after the lighting socket branch uses electricity is lower than the second proportion of the electricity consumption data collected at the previous point in time, it is also set to 50%, then the lighting socket is judged The branch road has stopped running at this time. For example, the electricity consumption data collected at the previous time point of the lighting socket branch was 4.0kWh, and the electricity consumption data collected at the later point in time was 0.9kWh, a change of 77% before and after, so it can be determined that the lighting socket branch stopped running at this time.
步骤C：计算建筑非运行时段照明插座支路的诊断指标值-照明插座非运行时段谷峰比值：Step C: Calculate the diagnostic index value of the lighting socket branch during the non-operating period of the building-the valley-to-peak ratio of the lighting socket during the non-operating period:
式(1)中，E
nl为非运行时段中某一小时时段照明插座支路用能值；E
pl为运行时段中，每小时时段照明插座支路用能高峰平均值。
Formula (1), E nl non-operating period in a light socket branch hour period energy value; E pl is the operating period, the light socket hour period the peak average energy branch.
步骤D：同类建筑类似用途照明插座支路横向对比，并按照明插座谷峰比值从小到大进行排列，如图2所示，为1:00～2:00非运行时段8栋建筑照明插座支路照明插座谷峰比值从小到大排列顺序图。Step D: Horizontal comparison of lighting socket branches for similar purposes in similar buildings, and arranged according to the peak-to-peak ratio of the bright sockets from small to large. As shown in Figure 2, the lighting sockets of 8 buildings are in the non-operating period from 1:00 to 2:00. The sequence diagram of the valley-peak ratio of the road lighting socket from small to large.
步骤E：基于横向对比排列的同类建筑类似照明插座支路的非运 行时段照明插座谷峰比值，确定非运行时段照明插座支路照明插座谷峰比值排列中的75％分位值作为判定临界值。如图3所示，1:00～2:00非运行时段8栋建筑照明插座支路照明插座谷峰比值按从小到大排列，计算可知其75％分位值，如图3中横线所示。75％分位值计算过程如下：Step E: Based on the non-operating period lighting socket valley-to-peak ratio of similar lighting socket branches of similar buildings arranged horizontally, determine the 75% quantile value in the non-operating period lighting socket branch lighting socket valley-to-peak ratio arrangement as the critical value . As shown in Figure 3, during the non-operating period from 1:00 to 2:00, the valley-to-peak ratios of the lighting sockets of the eight architectural lighting sockets are arranged from small to large, and the calculation shows that its 75% quantile value is shown by the horizontal line in Figure 3. Show. The 75% quantile calculation process is as follows:
①将样本总量按从小到大的顺序排列，其中数字的位置顺序，记为a，样本总量所含项数记为n。本案例中，一组数从小到大排列，处于第3个数的位置记为a＝3；样本总量n＝8；① Arrange the total number of samples in ascending order, where the position of the numbers is recorded as a, and the number of items contained in the total sample is recorded as n. In this case, a group of numbers are arranged from small to large, and the position of the third number is recorded as a=3; the total number of samples is n=8;
②75％分位值数所在位置，采用数字表示则为1+(n-1)×0.75。本案例中75％分位值数所在位置的数字表示为6.25，位于第6个数与第7个数之间。② The position of the 75% quantile value is 1+(n-1)×0.75 in digital representation. In this case, the number at the position of the 75% quantile is expressed as 6.25, which is located between the 6th and 7th numbers.
③将75％分位值所在位置的计算结果数字的整数部分记为c，小数部分记为d。本案例中c＝6，d＝0.25；③The integer part of the calculation result number at the position of the 75% quantile is recorded as c, and the decimal part is recorded as d. In this case, c=6, d=0.25;
④计算75％分位值LJ
75。计算公式为a(c)+[a(c+1)-a(c)]×d。本案例中a(c)表示从小到大排列处于第6位的数值，为21.2％；a(c+1)表示从小到大排列处于第7位的数值，为33.5％；则75％分位值LJ
75＝21.2％+(33.5％-21.2％)×0.25＝24.3％。
④Calculate the 75% quantile value LJ 75 . The calculation formula is a(c)+[a(c+1)-a(c)]×d. In this case, a(c) represents the value ranked 6th from small to large, which is 21.2%; a(c+1) represents the value ranked 7th from small to large, which is 33.5%; then it is 75%. The value LJ 75 =21.2%+(33.5%-21.2%)×0.25=24.3%.
步骤F：找出非运行时段中照明插座支路照明插座谷峰比值排列中等于或大于横向对比75％分位值的非运行时段照明插座支路谷峰比值。如图4所示，为1:00～2:00非运行时段8栋建筑照明插座支路照明插座谷峰比值横向对比排列图，等于或大于75％分位值的两栋建筑的照明插座支路分别为建筑III和建筑IV的照明插座支路，附图4中虚线矩形框所示。Step F: Find out the valley-to-peak ratio of the lighting socket branch during the non-operation period that is equal to or greater than the 75% quantile of the horizontal contrast in the lighting socket branch valley-to-peak ratio arrangement during the non-operation period. As shown in Figure 4, it is a horizontal comparison of the valley-to-peak ratio of the lighting socket branch of the eight buildings during the non-operation period from 1:00 to 2:00. The lighting sockets of the two buildings equal to or greater than 75% of the quantile value are arranged The roads are the branch roads of the lighting sockets of Building III and Building IV, as shown in the dotted rectangular box in Figure 4.
步骤G：给出诊断结论。对于非运行时段存在问题的照明插座支 路，确定对应的建筑，且通过监测平台给出警示信息，以及时提醒楼宇管理人员，采取措施，避免进一步浪费。Step G: Give a diagnosis conclusion. For the lighting socket branch that has problems during non-operation period, determine the corresponding building, and give warning information through the monitoring platform, prompt the building management personnel to take measures to avoid further waste.
综上所述，本发明创新提出基于能耗监测平台，针对建筑照明插座支路，开展非运行时段用能诊断，不但弥补非运行时段照明插座用能研究的空白，更为能耗监测数据服务于建筑用能设备的运维管理提供了一种新的探索思路和方向。In summary, the present invention innovatively proposes a non-operational period energy consumption diagnosis based on an energy consumption monitoring platform for building lighting socket branches, which not only makes up for the gap in the study of non-operational period lighting socket energy consumption, but also provides services for energy consumption monitoring data.
