The invention also provides a preferred embodiment, which provides a charging compatibility evaluation diagnosis method based on the network application method.
In order to obtain the weight values of 41 lower-layer indexes such as a low-voltage auxiliary power supply and the like to 4 upper-layer indexes such as electrical performance and the like, a neural network model needs to be established for 4 times of solving calculation. Taking the electrical performance index as an example, the acquired and summarized 11 subordinate index data such as the low-voltage auxiliary power supply of the charging equipment in Beijing City are input into a BP neural network as learning samples to be learned, the corresponding electrical performance result is used as an output layer, a neural network model is established to carry out intelligent training and simulation, and the weight of the 11 subordinate indexes on the electrical performance index is obtained.
In an evaluation model of the charging pile, quantitative indexes and qualitative indexes exist, the dimension and the magnitude are different, direct comparison cannot be achieved, and quantification is carried out by adopting different methods.
1) Conversion of quantitative index value into evaluation index value
There are many quantifiable index values in the compatibility evaluation index. For example, current output errors, voltage output errors and the like of various types of chargers can be detected by detection equipment. These index values are not only different in dimension but also different in order of magnitude, and if not processed, these indices are not comparable.
The item enables different dimension indexes to be comparable by carrying out non-dimensionalization processing on actually measured index data. The specific method comprises the following steps:
the ideal state of each index is the optimum state, and if the voltage output error is the optimum state, the voltage output error index value is 10 minutes, and the voltage output error index value is 10 after evaluation. When the charger operates, the measured value deviates from the optimal state, the measured value is compared with the optimal value, the measured value is converted into an evaluation value in a certain mode, and then the comprehensive evaluation values of all items are obtained through comprehensive evaluation. The larger the difference between the actual measurement value and the optimal value of the charging pile is, the smaller the obtained evaluation value is. For the measurable evaluation index of the charging pile, a dimensionless function is adopted:
wherein x0 is the optimum value, xmax、xminRespectively, an allowable maximum value and a minimum value.
FIG. 2 is a schematic diagram of a linear non-dimensionalized model according to an embodiment of the present invention, as shown in FIG. 2, when the actual measurement value of the index deviates from the optimal value to some extent, the index can be considered to be in a dangerous state, and the value is referred to as a critical value at the time of evaluation, and the upper diagram corresponds to xmax、xminThe comment may be 0 points, and these two values may be determined by a method of expert investigation. The influence difference of the measurable points on the overall state of the charger is not considered, for example, the standard value of the output voltage error of the charging pile is not more than +/-5%, and the deviation degree is assumed to be 5% or-5%, namely, the index evaluation values are all considered to be 0.
2) Conversion of qualitative index value into evaluation index value
In the comprehensive evaluation method, only a single numerical value can be used to describe the state of an object. Because there are many factors influencing the index state, the recognition diversity of people on objects and the uncertainty of the evaluation process generally cannot reflect the ambiguity of the judgment result if the uncertainty is quantified by using a deterministic numerical value, and the ambiguity does not conform to the reality. If the interval number is used for representation, the fuzzy understanding of people on the state can be well reflected. When the electrical performance and the charging compatibility of the charging facility are evaluated, a plurality of experts generally participate, the levels of the experts are different, and in order to enable the evaluation result to better reflect the actual state of the charging pile, an integrated value statistical analysis method is used for processing the evaluation index value.
When a plurality of experts evaluate the interval value of a certain index, the weights or evaluation values of opinions of the experts can be integrated by adopting a value-collecting statistic method.
Setting an interval estimate of some index as [ u ]1 (k)，u2 (k)]Where k is 1,2, …, and n denotes the kth evaluator, there is a statistical sequence of sets:
the n subsets are superimposed to form a distribution that is overlaid on the evaluation value axis.
Fig. 3 is a schematic diagram of an index evaluation value distribution diagram according to an embodiment of the present invention, and the distribution shown in fig. 3 can be described by the following formula:
wherein the content of the first and second substances,
The method comprises the following steps of obtaining the weight of a lower-layer index to an upper-layer index and the weight of an upper-layer index to a total target based on a hierarchical evaluation index system of charging pile compatibility, converting an actually measured quantitative/qualitative index value into an evaluation index value through a dimensionless function and an aggregate statistical method, and obtaining a comprehensive evaluation value of charging pile compatibility:
wherein, P is the compatible comprehensive evaluation value of charging pile, wiIs the weighted value of the upper layer index to the total target, qi is the number of lower layer indexes contained in the ith upper layer index, kjIs the weighted value of the lower index to the upper index, XjAnd the evaluation index value is the evaluation index value after the actual measurement index is converted.
According to the technical scheme provided by the invention, the weights of the lower-layer indexes to the upper-layer indexes and the weights of the upper-layer indexes to the total target can be obtained according to the established neural network model and the established hierarchical analysis model. And then, scoring and evaluating each index factor item of the charging pile.
The quantitative indexes are normalized by a non-dimensionalization function, and the result and the original data are ensured to be distributed the same; and the qualitative indexes are processed by adopting an integrated statistical analysis method, and compared with the traditional expert scoring evaluation method, the method can process the expert opinions more scientifically and reasonably, so that the evaluation result is more accurate and reliable.
