Row study and training, by adjusting the weights between network structure and network node, make neutral net fitting air conditioner operation parameters and
Relation between frosting state, neutral net is finally set accurately to fit between the operational factor of air-conditioning and condenser frosting state
Corresponding relation.
Such as:Network structure, network node, all it is the term of field of neural networks, node is neuron, represents a kind of spy
Fixed output function, structure are the composition situation of whole neutral net, the summary of connection.
Such as:Relation between network structure and network node, it can include:Network structure, can be by each network node

Good if (several similar structures can also be preset, the later stage selects most suitable according to the situation of network training), the adjustment of weights
It may refer to the network training in following step 4 once and test.
Wherein, specific implementation step is as follows:
Step 1, data collection:
Collect itself running state parameter and corresponding frosting situation of the air-conditioning under different use environments.It is specific to collect
Mode, which includes but is not limited to operational factor of the air-conditioning under laboratory simulation environment, actual user is collected by technology of Internet of things makes
The modes such as the air conditioner operation parameters of used time.
Step 2, sample data selection:
By the analysis to data and expertise knowledge is combined, is chosen on the influential parameter conduct of air-conditioning frosting state
Input parameter, using frosting state as output parameter.In this programme, input parameter includes but is not limited to following one kind or more
Kind:The environment temperature of indoor and outdoor, air-conditioning design temperature, wind speed setting (shelves), condenser temperature, outdoor fan running current etc..
Input parameter is not only single parameter, includes the input parameter one or more dimensions array for extracting feature composition according to certain rules yet.
By obtained input, output parameter pair, a part is used as training book sample data, and a part is used as test sample number
According to.
Step 3, network structure design:
The data characteristic influenceed according to different design temperatures, environment temperature, shell temperature etc. on operation of air conditioner and its institute
The rule contained, the basic structure of network, the input of network, output node number, network hidden layer number, hidden node can be primarily determined that
Number, network initial weight etc..
Such as:The data influenceed on operation of air conditioner, can come from all service datas collected in step 1, also may be used
To be a few items therein.
Such as:The characteristic of the data influenceed on operation of air conditioner and its rule contained, such as frosting here, frosting
Intuitively there is relation with condenser temperature very, temperature is lower, and the possibility and thickness of frosting can be bigger, therefore first can be
Condenser temperature is as input parameter.
Wherein, neural network algorithm schematic diagram such as Fig. 1 of the invention, specific artificial neural network structure include but is not limited to
Three kinds of network structures below:
(1) BP neural network
BP neural network structural representation is as shown in Figure 10, during practical application, can adjust input layer, hidden as needed
Layer, output layer nodes and hidden layers numbers.
Such as:Such as 8 output parameters are determined, and the frosting situation exported has 10 kinds, then can tentatively choose defeated
It is 8 to enter node layer number, and output layer nodes are 10;And intermediate layer rule of thumb chooses 5, behind training result is bad to carry out
Adjustment.
(2) CNN convolutional neural networks
Multilayer convolutional network, exactly constantly extract merging from the feature of low dimensional and obtain the feature of more higher-dimension, so as to
For being classified or inter-related task.
Multilayer convolutional network structural representation is as shown in figure 11, and network structure can be adjusted according to actual conditions during practical application
It is whole.
(3) residual error neutral net
When debugging CNN networks, deepen the network number of plies and change the method for convolution kernel size, network can not be showed
Get a promotion.Front and rear data can preferably be connected by adding residual block, strengthen feature representation ability, so it can strengthen convolution
The learning ability of network.As shown in figure 13, the input of certain section of neutral net is x, and desired output is H (x), and input x is passed to
Output as after initial configuration, it is necessary to learn target be just changed into F (x)=H (x)-x.
Residual error neural network structure schematic diagram is as shown in figure 12, and network structure can be adjusted according to actual conditions during practical application
It is whole.
That is, the artificial neural network used in this programme, is not limited to a certain network structure, can be through
The artificial neural network of allusion quotation such as BP neural network or high-level manual's neutral net, or deep learning network such as CNN
(convolutional neural networks) and RNN (Recognition with Recurrent Neural Network) etc., concrete scheme can select according to practical application scene.
Step 4, network training and test:
After the completion of network design, training sample data need to be used, network is trained.
Training method can be adjusted according to the problem of discovery in the network structure of reality and training.Herein only for this hair
Bright one of which method is illustrated below:
(1) input data x is imported, according to activation primitive, the weights of initialization and biasing, calculates the reality output a of network
(x), i.e. a (x)=1/ (1+e-z), wherein Z=Wk*x+bl。
(2) judge whether the desired output y (x) and reality output a (x) of network meet output accuracy requirement, i.e.,:
‖y(x)-a(x)‖<∈, ∈ are target minimal error.
(3) terminate to train if required precision is met, update the weights W of network according in the following manner if being unsatisfactory fork,
Bias bl:
C (w, b) is error energy function (by taking standard variance function as an example), and n is the total quantity of training sample, summation be
Carried out on total training sample x:
Update each layer weights:
Update each layer biasing:
Wherein:
WkFor initial weight,For the partial derivative of error energy function pair weights, blFor initial bias,For error energy
Partial derivative of the flow function to biasing;Value can be obtained by chain type Rule for derivation, until network output error it is small
Untill ∈ (target minimal error).
After the completion of network training, then with test sample positive test network.When test error is unsatisfactory for requiring, then repeat
