As shown in fig. 1, a flowchart for implementing the rescue data fusion method provided by the embodiment of the present invention is shown, and the details are as follows:
in step 101, a monitoring dataset is acquired, wherein the monitoring dataset is acquired based on status monitoring points of a rescue scene.
In step 102, the monitoring dataset is added to a sample set library, and the degree of deviation of the monitoring dataset from the sample set library is determined by counting the number of classification times required for classifying the monitoring dataset into independent classes from the sample set library, wherein the degree of deviation is inversely related to the number of classification times, and the sample set library comprises a plurality of sample monitoring datasets.
In some embodiments, the step 102 includes:
constructing a plurality of first monitoring arrays according to the sample set library, wherein the plurality of first monitoring arrays correspond to a plurality of state monitoring points;
normalizing the plurality of first monitoring arrays to obtain a plurality of second monitoring arrays;
arranging each second monitoring array in the plurality of second monitoring arrays according to the values in the arrays, so as to obtain a plurality of first queues;

and determining the deviation degree according to the classification times and the number of data sets in the sample set library.
In some embodiments, the classifying the sample set library according to the plurality of first queues until the monitoring data sets are independently classified comprises:
randomly selecting a first queue from a plurality of first queues as a first target queue;
Generating a classification random number between 0 and 1;
performing two classifications on the data in the first target queue according to the classification random number;

determining the deviation degree according to a first formula, the average value and the number of data sets in the sample set library, wherein the first formula is as follows:
In the method, in the process of the invention,for the degree of deviation->Is a positive number less than 1, +.>For a round-up function->For the number of data sets in the sample set library, +.>Is the average value.
For example, in the fire rescue process, good combat command strategies are indistinguishable from timely field data and field state analysis, and the field data may include: images, videos, gas monitoring data, temperature monitoring data and the like of the rescue scene. In order to reliably and timely transmit the data to the command platform, the embodiment of the invention fuses the data so as to improve the efficiency of data transmission.
To achieve the above object, data acquired in the same period is first aggregated into a data set. Before fusion, the embodiment of the invention firstly verifies the data set, and aims to determine whether fusion conditions exist or not, and whether data are abnormal or not.
In terms of classification method, the embodiment of the present invention reorganizes the data in the sample set library added to the monitoring dataset, as shown in fig. 2, which shows the reorganization process, and the plurality of datasets 201 respectively extract the data from the predetermined time to reorganize the data into arrays, so as to obtain a plurality of arrays, and the arrays respectively perform normalization processing to form normalized arrays, and the normalized arrays are arranged according to the sizes of the elements in the arrays, so as to construct a plurality of queues 202.
It is contemplated that each queue 202 includes a data element derived from the monitoring dataset. For example, monitoring the data set 201 includes: data1, data2 … … DataN, forming a queue 202 by combining, normalizing and ordering as described above: q1, Q2 … … QM, each queue has one element corresponding to the monitored dataset and its location becomes unfixed due to reordering, for a Q1 queue the data corresponding to the monitored dataset may be located at a position a and for a Q2 queue the data corresponding to the monitored dataset may be located at a position b, but for each queue there is always one element corresponding to the monitored dataset, and similarly for other sample datasets in the plurality of datasets 201 there is the same corresponding element in each queue 202.
In terms of classification, the embodiment of the invention randomly extracts one queue from the queues each time, randomly generates a random number between 0 and 1, takes the random number as a classification interval, divides the extracted queue into two sections of sub-queues, finds the sub-queues containing corresponding monitoring data sets, checks the number of elements in the sub-queues, and if the number of elements is larger than 1, the monitoring data sets are not independent and successful. At this time, a queue is randomly extracted from the queues again, data deletion operation is carried out on the re-extracted queue, elements contained in the deleted queue are identical to data sets corresponding to elements containing sub-queues corresponding to the monitoring data sets, at this time, random number generation, segmentation and independent analysis are carried out on the deleted queue again, the above-mentioned processes are repeated until the elements corresponding to the monitoring data sets are independent, and the times of extracting the queue are counted and used as classification times.
It can be seen that the above classification process has a certain uncertainty, so that the embodiment of the invention executes the classification process for a plurality of times, counts the classification times required for separating the monitoring data set for a plurality of times, calculates the average value of the classification times, and calculates the deviation degree of the monitoring data set and the data set in the sample set library by using the first formula:
In the method, in the process of the invention,for the degree of deviation->Is a positive number less than 1, +.>For a round-up function->For the number of data sets in the sample set library, +.>Is an average of a plurality of classification times.
From the above equation, it can be seen that the degree of deviation is inversely related to the number of classification times, and the smaller the average value of the number of classification times is, the larger the deviation is.
In one embodiment, a plurality of monitoring data sets are obtained before fusion, and the monitoring data sets which are easy to repeatedly appear are selected to be added into the sample set library, so that the sample set library is obtained.
In step 103, when the deviation degree is smaller than a deviation threshold, the monitoring data set is input into a fusion model, and the monitoring data set is fused, wherein the fusion model is constructed according to the sample set library, and the fusion model is used for outputting fusion data according to the input data and restoring the monitoring data set according to the fusion data.
In some embodiments, the fusion model is constructed from the sample set library, comprising:
obtaining a fusion basic model, wherein the fusion basic model comprises a first model and a second model, the first model is provided with a plurality of inputs and a fusion output, the second model is provided with a fusion input and a plurality of outputs, the fusion input of the second model receives the output of the first model, and the number of the plurality of inputs of the first model is the same as the number of the plurality of outputs of the second model;
Dividing a plurality of sample monitoring data sets in the sample set library into a first portion and a second portion, wherein the first portion and the second portion respectively comprise a plurality of sample monitoring data sets;
first partial input: sequentially inputting a plurality of sample monitoring data sets of the first part into a plurality of inputs of the first model, and adjusting parameters of the first model and parameters of the second model according to deviation between a plurality of restoring outputs and the input sample monitoring data sets after each input until the deviation between the plurality of restoring outputs and the input sample monitoring data sets is smaller than a threshold value, wherein the input sample monitoring data sets are data sets input into the first model, and the plurality of restoring outputs are a plurality of outputs of the second model;
sequentially inputting a plurality of sample monitoring datasets of the second portion to a plurality of inputs of the first model;
determining a total deviation according to a plurality of verification deviations, wherein the verification deviation is a deviation between the input sample monitoring data set and a plurality of reduction outputs after each input sample monitoring data set of the second part, and the total deviation represents the deviation of the first model and the second model;
And if the total deviation is greater than a total deviation threshold, reducing the number of the first model parameters and the number of the second model parameters and jumping to the step of inputting the first part.
In some embodiments, the first model is:
in the method, in the process of the invention,for the output of the first model, +.>The +.f. of the output function for the first model>Personal weight(s)>Is the +.>Line->Output of column intermediate function, +.>Is a first bias constant of the first model, < ->Is the +.>Line->Output of intermediate function of column, +.>Is the +.>Line->Column intermediate function->Weight parameters->Is the +.>Line->Output of column intermediate function, +.>Total number of rows of intermediate function for the first model, < >>For the propagation function +.>Is the +.>The output of the individual input nodes,/>Is the +.>Weight parameters of the individual input nodes,/>Is->Input data->Is the +.>Line->Output of column intermediate function, +.>Is the +.>Line->Column intermediate function->A number of weight parameters;
the second model is:
in the method, in the process of the invention,is the +.>Output(s)>The +.f. of the output function for the second model >Personal weight(s)>Is the +.>Line->Output of column intermediate function, +.>Is the first bias constant of the second model, +.>Is the +.>Line->Output of intermediate function->Is the +.>Line->Column intermediate function->Weight parameters->Is the +.>Line->Output of column intermediate function, +.>For the output of the input node of the second model, +.>Weight parameter for input node of the second model, < ->Is the +.>Line->Output of column intermediate function, +.>Is the +.>Line->Column intermediate function->And a weight parameter.
In some embodiments, the propagation function is:
in the method, in the process of the invention,for input quantity, < >>Is a prepositive constant, < >>Is a natural constant.
By way of example, the embodiment of the invention determines the deviation degree of the monitoring data set and the sample set library according to the steps, and when the deviation is smaller, the data sets can be fused to generate fused data.
In the aspect of fusion, the embodiment of the invention only needs to input the monitoring data set into the fusion model, and the fusion model outputs one fused data. And for the receiving end, the data after the fusion is received is restored by the fusion model.
The fusion model provided by the embodiment of the invention comprises a first model and a second model, wherein the first model inputs data of a data set, outputs fused data, and the second model inputs fused data and outputs a restored data set, and in some application scenes, the formula of the first model is as follows:
in the method, in the process of the invention,for the output of the first model, +.>The +.f. of the output function for the first model>Personal weight(s)>Is the +.>Line->Output of column intermediate function, +.>Is a first bias constant of the first model, < ->Is the +.>Line->Output of intermediate function of column, +.>Is the +.>Line->Column intermediate function->Weight parameters->Is the +.>Line->Output of column intermediate function, +.>Total number of rows of intermediate function for the first model, < >>For the propagation function +.>Is the +.>The output of the individual input nodes,/>Is the +.>Weight parameters of the individual input nodes,/>Is->Input data->Is the +.>Line->Output of column intermediate function, +.>Is the +.>Line->Column intermediate function->A number of weight parameters;
the second model is:
in the method, in the process of the invention, Is the +.>Output(s)>The +.f. of the output function for the second model>Personal weight(s)>Is the +.>Line->Output of column intermediate function, +.>Is the first bias constant of the second model, +.>Is the +.>Line->Output of intermediate function->Is the +.>Line->Column intermediate function->Weight parameters->Is the +.>Line->Output of column intermediate function, +.>For the output of the input node of the second model, +.>Weight parameter for input node of the second model, < ->Is the +.>Line->Output of column intermediate function, +.>Is the +.>Line->Column intermediate function->And a weight parameter.
In the above equation, the propagation function is:
in the method, in the process of the invention,for input quantity, < >>Is a prepositive constant, < >>Is a natural constant.
From the two formulas above, it can be seen that the two models have the same model respectively. When the method is applied to data fusion, the fused data can be obtained by only inputting the data into the first model. If the fused data is sent to the remote end, the remote end receives the fused data, and the data can be restored through the second model.
The two formulas are basic models, and for the determination aspect of parameter values, the invention solves through a sample monitoring data set in a sample set library.
In terms of solving parameter values, firstly, a sample monitoring dataset in a sample dataset library is divided into two parts, the sample monitoring dataset of the first part is sequentially input into a first model, after each part is input, a restored dataset is output in a second model, a deviation is calculated according to the restored dataset and the input dataset, a back propagation algorithm is adopted according to the deviation to adjust parameters until the deviation between the restored dataset output by the second model and the input dataset is smaller than a threshold value, at the moment, the sample monitoring dataset of the second part is sequentially input into the first model, a plurality of restored datasets are obtained in the second model, the total deviation is determined according to the obtained restored datasets and the input datasets, and if the total deviation is larger than the total deviation threshold value, the number of parameters in the first model and the second model is reduced, for example, the total number of columns is reduced, so that the total number of parameters is reduced. And after the reduction, the parameter determination operation is carried out again.
