Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
According to one or more embodiments, a method for diagnosing the service capability of the architectural lighting socket support in the non-operation period is disclosed, as shown in fig. 1, and specifically comprises the following steps:
step A: the type of building in which the lighting socket branch for the non-operational period is located is identified. The building types aimed by the invention mainly comprise office buildings, market buildings with obvious operation and non-operation time periods, and do not comprise medical and health buildings, hotel buildings and non-stop buildings all the year round.
And B: and identifying the starting time point and the stopping time point of the architectural lighting socket branch through the energy consumption monitoring platform data. The starting and stopping time points of the lighting socket are judged through the change of the wave peaks and the wave troughs of the electricity used by the branches of the building lighting socket, the collected current electricity data is compared with the electricity data of the previous time point, and the starting and stopping time points are identified according to the set first proportion and the set second proportion.
The identification of the point when the lighting socket branch starts to operate is as follows: if the power consumption data collected at the later time point of the power consumption of the branch of the lighting socket is higher than the first proportion of the power consumption data collected at the previous time point, namely 50%, the lighting socket is judged to start to operate at the moment. If the collected power utilization data of the lighting socket at the previous time point is 1.5kWh, and the collected data of the lighting socket at the later time point is 4.5kWh, the change is 200% in the front-back direction, so that the lighting socket branch can be determined to start to operate at the moment.
The identification of the time point when the lighting socket branch stops running is as follows: if the power consumption data collected at the later time point of the power consumption of the illumination socket branch is lower than the second proportion of the power consumption data collected at the previous time point, the same setting is 50%, and then the illumination socket branch is judged to stop running at the moment. If the power consumption data collected at the previous time point of the lighting socket branch is 4.0kWh, the power consumption data collected during the operation at the later time point is 0.9kWh, and the change is 77% from front to back, the lighting socket branch can be determined to stop operating at the moment.
And C: calculating the ratio of the diagnosis index value of the lighting socket branch in the non-operation period to the valley peak value of the lighting socket in the non-operation period:
in the formula (1), EnlAn illumination outlet branch energy value for a certain hour period in the non-operational period; eplThe average of peak energy levels for the lighting jack legs during the hours of operation is the hourly time period.
Step D: similar-purpose lighting socket branches of the same kind of buildings are transversely compared and arranged from small to large according to the valley-peak ratio of the bright sockets, and as shown in fig. 2, the valley-peak ratio of the lighting sockets of 8 buildings in the non-operation period of 1: 00-2: 00 is arranged from small to large in sequence.
Step E: and determining 75% of quantiles in the arrangement of the valley-peak ratio of the illumination sockets of the similar illumination socket branches of the same type of buildings as a judgment critical value based on the valley-peak ratio of the illumination sockets of the similar illumination socket branches of the same type of buildings in transverse comparison arrangement in the non-operation period. As shown in fig. 3, the valley-peak ratios of the lighting sockets of the 8 branches of the building lighting socket in the non-operation period of 1: 00-2: 00 are arranged from small to large, and the 75% quantile value is obtained through calculation, as shown by the horizontal line in fig. 3. The 75% quantile value calculation procedure is as follows:
arranging the total amount of the samples from small to large, wherein the position sequence of the numbers is marked as a, and the number of items contained in the total amount of the samples is marked as n. In this case, a group of numbers is arranged from small to large, and the position at the 3 rd number is recorded as a being 3; the total amount n of the samples is 8;
and the positions of 75% fractional value numbers are 1+ (n-1) multiplied by 0.75 by adopting the number expression. The number at which 75% of the fractional digits are located in this case is indicated as 6.25, which is between the 6 th and 7 th numbers.
And thirdly, recording the integer part of the calculation result number of the position where the 75% quantile value is located as c, and recording the decimal part as d. In this case, c is 6, d is 0.25;
fourthly, calculating 75 percent quantile value LJ75. The formula is a (c) + [ a (c +1) -a (c)]X d. In this case, a (c) represents a value at the 6 th digit in the order from small to large, and is 21.2%; a (c +1) represents a value at the 7 th digit in the descending order, which is 33.5%; then 75% quantile value LJ75＝21.2％+(33.5％-21.2％)×0.25＝24.3％。
Step F: and finding out the valley-peak ratio of the illumination socket branch in the non-operation period, wherein the valley-peak ratio of the illumination socket branch in the non-operation period is equal to or more than the 75% horizontal contrast fractional value in the arrangement of the valley-peak ratios of the illumination socket branch in the non-operation period. As shown in fig. 4, the lighting socket valley-peak ratio transverse comparison arrangement diagram of 8 building lighting socket branches in the non-operation period of 1:00 to 2:00 is shown, the lighting socket branches of two buildings equal to or greater than the 75% quantile value are lighting socket branches of a building III and a building IV respectively, and the dotted line rectangular frame in fig. 4 is shown.
Step G: a diagnostic conclusion is given. And determining a corresponding building for the lighting socket branch which has a problem in the non-operation period, giving out warning information through the monitoring platform, and timely reminding building managers to take measures to avoid further waste.
In conclusion, the invention innovatively provides an energy consumption monitoring platform, and aims at building lighting socket branches to carry out energy consumption diagnosis in non-operation time periods, so that the blank of research on energy consumption of lighting sockets in non-operation time periods is made up, and a new exploration idea and direction are provided for operation and maintenance management of building energy consumption equipment by using energy consumption monitoring data.
