It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, the method for monitoring pollution indexes of a gas internal combustion engine according to the embodiment of the invention is provided. The method provided by the embodiment of the invention can be applied to an application client, and particularly can be applied to a server or a general computer. In this embodiment, the method specifically includes the following steps:
and step 101, sending a pollution index monitoring model request of the gas internal combustion engine to a joint learning server.
Specifically, an application client of the gas internal combustion engine sends a pollution index monitoring model request of the gas internal combustion engine through an API interface, namely, a pollution index monitoring model call is initiated. Optionally, the application client is provided on a local server. An application client is understood to be a client for meeting the business requirements of a gas combustion engine, for example, a client for predicting pollution index data, fault types of a gas combustion engine, and in the scenario of monitoring pollution indexes, the application client does not participate in joint learning, only as a party to a model application, in other words, the gas combustion engine does not participate in joint learning.
Specifically, the joint learning server is used for joint learning with a joint learning client (a client for joint learning) to obtain a joint learning model, and storing the joint learning model, and is also used for providing the model for an application client. And the method can be applied to the interaction scene of at least one application client and one joint learning server, or can also be applied to the interaction scene of at least one application client and a plurality of joint learning servers, namely, a model database to be called is arranged on each joint learning server, wherein any joint learning server can provide services for the application client, and the calling of the model in the model database is realized. It can also be appreciated that in the two scenarios described above, each joint learning server may be provided with a model database and a control layer. The model database stores at least one joint learning model, and the control layer can realize the calling of the model in the model database based on the request of the model calling of the application client.
Step 102, receiving a pollution index monitoring model sent by the joint learning server.
The pollution index monitoring model is used for predicting pollution index data of the gas internal combustion engine.
And step 103, determining pollution index data of the gas internal combustion engine according to the pollution index monitoring model.
In particular, the pollution index data comprises the concentration of nitrogen oxides and/or carbon monoxide.
In some possible implementations, the pollution index monitoring models are multiple, the multiple pollution index monitoring models are screened based on service information of the pollution index monitoring models, the target pollution index monitoring model is determined, and the pollution index data of the gas internal combustion engine is predicted based on the target pollution index monitoring model and the operation data of the gas internal combustion engine. It should be understood that the service information indicates the application of the model, and the reference value of the predicted pollution index data of the gas internal combustion engine is ensured based on the actual application of the model. Specifically, step 103 includes:
and receiving service information of the pollution index monitoring model sent by the joint learning server.
Determining a target pollution index monitoring model from the pollution index monitoring models according to the service information of the pollution index monitoring models;
And determining pollution index data of the gas internal combustion engine according to the target pollution index monitoring model and the operation data of the gas internal combustion engine.
It is understood that the service information refers to the relevant information generated by applying the pollution index monitoring model and the relevant information of the pollution index monitoring model itself. Specifically, the service information includes the number of model downloads, the model download users, the source of model training data, the amount of model training data, the model accuracy, the model generation time, and the number of model updates. The model accuracy is determined based on feedback data uploaded by an application client using the model, wherein the feedback data comprises a predicted value and an actual value. It should be noted that, the above service information is merely an example, in practical application, the service information may be various, and specifically, a field name corresponding to the service information that is desired to be obtained may be preset according to an actual service requirement, and the field name corresponding to the service information is encapsulated in the request, so that the request carries the field name corresponding to the service information. The operation data of the gas internal combustion engine is data generated in the operation process of the gas internal combustion engine, including but not limited to on-off state, gas flow, gas temperature, gas pressure, air temperature, air flow, water supply temperature, main steam pressure, main steam temperature and main steam flow, and is specifically determined according to practical situations.
As a possible case, based on the service information of the pollution index monitoring model, the plurality of pollution index monitoring models are automatically screened, the target pollution index monitoring model is determined, and the user experience is improved. Specifically, the target pollution index monitoring model may be determined by:
and acquiring the model requirements of the gas internal combustion engine, and selecting each pollution index monitoring model according to the model requirements and the service information of each pollution index monitoring model so as to determine a target pollution index monitoring model.
The model requirement refers to a condition that the model should meet, and includes a plurality of model conditions, for example, the model accuracy requirement, the model generation time requirement, the model downloading frequency requirement, the model training data volume requirement and the like, and the target pollution index monitoring model is a joint learning model meeting the model requirement. In a first example, if only one pollution index monitoring model meets the model requirement, determining the pollution index monitoring model as a target pollution index monitoring model; in a second example, if two or more pollution index monitoring models meet the model requirements, determining the pollution index monitoring models as target pollution index monitoring models respectively; in a third example, setting respective priorities of different model conditions in the model requirements, determining model conditions met by the pollution index monitoring model for each pollution index monitoring model, and determining scores of the pollution index monitoring models according to the priorities of the model conditions met by the pollution index monitoring model; then, the pollution index monitoring model with the largest score is determined as the target pollution index monitoring model.
As another possible case, the service information of the pollution index monitoring model is displayed to interact with the user, and the user selects the target pollution index monitoring model to determine the target pollution index monitoring model so as to meet the user requirements. Specifically, the target pollution index monitoring model may be determined by:
displaying respective icons of the pollution index monitoring models and respective business information of the pollution index monitoring models, and determining a target pollution index monitoring model from the pollution index monitoring models according to the acquired external trigger information.
Specifically, the application client corresponding to the gas internal combustion engine displays respective icons and respective business information of all pollution index monitoring models, so that a user knows the application condition of the models and the condition of the models, then clicks the pollution index monitoring models to download, determines the downloaded pollution index monitoring models as target pollution index monitoring models, interacts with the user, and ensures the reference value of the target pollution index monitoring models.
In the above embodiment, when there are a plurality of target pollution index monitoring models, the pollution index data of the gas internal combustion engine predicted by each target pollution index monitoring model is averaged to obtain the pollution index data of the gas internal combustion engine.
Referring to fig. 6, assuming that the carbon monoxide concentration of the gas internal combustion engine C1 in the energy station C is to be predicted, the monitoring client Cc in the local operation and maintenance server sends a pollution index monitoring model request, then the monitoring client Cc receives the pollution index monitoring model sent by the joint learning server S, predicts the carbon monoxide concentration of the gas internal combustion engine C1 according to the pollution index monitoring model, and uploads the prediction result to the joint learning server S, and if a true value exists, uploads the true value to the joint learning server S.

As shown in fig. 2, another method for monitoring pollution indexes of a gas internal combustion engine according to an embodiment of the present invention is provided. The method provided by the embodiment of the invention can be applied to a joint learning server, and can be particularly applied to a server or a general computer. In this embodiment, the method specifically includes the following steps:

Before model call is performed, whether a model corresponding to a pollution index monitoring model request exists in a model database needs to be determined, and only the model call can be realized.
In some possible implementations, the model database includes models to be called and respective model information of each model to be called; specifically, step 202 includes:
and judging whether the models to be called are matched with the models corresponding to the pollution index monitoring model request according to the model information of the models to be called aiming at each model to be called.
The model database is used for storing the model to be called and the model information of the model to be called, and specifically, the model to be called is a joint learning model. The model information is used to describe information of the model to be called, and may be, for example, information of model use, model name, number of model downloads, model download user, model training data source, model training data amount, model precision, model generation time, number of model updates, and the like.
Specifically, according to the model information of the model to be called, judging whether the model to be called is a model corresponding to the pollution index monitoring model request, and in practical application, when the pollution index monitoring model name exists in the model information, or words with the same meaning as the pollution index monitoring model name but different expressions are expressed, describing that the model to be called corresponding to the model information is the model corresponding to the pollution index monitoring model request. At the moment, extracting a model corresponding to the pollution index monitoring model request from a model database, and completing model calling.
And 203, determining a pollution index monitoring model according to a judging result of judging whether the model corresponding to the pollution index monitoring model request exists in the model database.
In some possible implementations, the determination result includes a model corresponding to the pollution index monitoring model request existing in the model database; step 103 comprises:
and determining a model corresponding to the pollution index monitoring model request from the model database, and determining the model corresponding to the pollution index monitoring model request as a pollution index monitoring model.
In some possible implementations, when the model corresponding to the pollution index monitoring model request exists in the model database, the method further includes:
Determining service information of the pollution index monitoring model from the model database;
and sending the service information of the pollution index monitoring model to the application client.
The respective service information of the pollution index monitoring model is sent to the application client, so that a user can know the condition of the model, and the user can conveniently select the model, thereby ensuring the accuracy of predicted pollution index data.
In some possible implementations, the determination result includes that the model corresponding to the pollution index monitoring model request does not exist in the model database; step 103 comprises:
selecting a combined gas internal combustion engine, wherein the combined gas internal combustion engine passes through a combined learning invitation, and the similarity between the combined gas internal combustion engine and the gas internal combustion engine is not smaller than a preset threshold;
performing joint learning according to respective model training data sets of the joint gas internal combustion engines to obtain respective local pollution index monitoring models;
determining a combined pollution index monitoring model according to each local pollution index monitoring model;
and determining the combined pollution index monitoring model as a pollution index monitoring model.
Each energy station is used as a node in the Internet of things, a client is arranged, if data in the energy station is used for joint learning, the energy station is called a joint energy station, a gas internal combustion engine in the energy station is called a joint gas internal combustion engine, and a client corresponding to the energy station is called a joint learning client. The joint learning ensures that the private data of the user is protected to the greatest extent through the distributed training and encryption technology, so that the trust of the user on the artificial intelligence technology is improved. In the embodiment of the application, under the joint learning mechanism, each participant (the joint learning client corresponding to each joint gas internal combustion engine) contributes the encrypted data model to the union and jointly trains a joint model. And uploading the gas internal combustion engine operation data of the combined gas internal combustion engine to a corresponding combined learning client, and storing the gas internal combustion engine operation data by the combined learning client.
In this embodiment, when there is no model corresponding to the pollution index monitoring model request in the model database, a model needs to be built at this time. Determining a combined gas internal combustion engine similar to the gas internal combustion engine in the energy station; and then, carrying out joint learning based on respective model training data sets of the joint gas internal combustion engines to obtain a local pollution index monitoring model, wherein the model training data sets comprise gas internal combustion engine operation data of the joint gas internal combustion engines, and specifically, the gas internal combustion engine operation data comprise on-off state, gas flow, gas temperature, gas pressure, air temperature, air flow, water supply temperature, main steam pressure, main steam temperature, main steam flow and historical flue gas oxygen content (label). And then, determining a combined pollution index monitoring model based on each local pollution index monitoring model, and determining the combined pollution index monitoring model as a pollution index monitoring model. The local pollution index monitoring model is a model obtained by model training based on a model training data set of the combined gas internal combustion engine, or a model obtained by model training based on model training data sets of a plurality of combined gas internal combustion engines in a combined learning client.
The combined gas internal combustion engine can be determined specifically by the following 2 implementation modes:
in the embodiment 1, the joint gas internal combustion engine is determined based on the description information of the candidate gas internal combustion engines that can participate in the joint learning and the description information of the gas internal combustion engines, and the joint gas internal combustion engine and the gas internal combustion engine are similar. Specifically, the combined gas internal combustion engine may be determined by the following implementation:

Wherein the descriptive information includes a plurality of parameters and parameter values for each parameter. The above parameters include, but are not limited to, rated capacity, rated efficiency, operating mode, model (indicating the performance, specification and size of the gas internal combustion engine), brand, and job site, as specifically needed to be determined in conjunction with the actual situation. It can be appreciated that the higher the similarity between the description information of the gas internal combustion engine and the description information of the combined gas internal combustion engine, the higher the reference value of the combined gas internal combustion engine, so as to ensure the accuracy of the combined gas internal combustion engine predicted subsequently. Preferably, the gas combustion engine and the combined gas combustion engine should be identical in model. Optionally, the similarity of each parameter in the description information of the gas internal combustion engine and the candidate gas internal combustion engine is determined based on the parameter value of each parameter in the description information of the gas internal combustion engine and the candidate gas internal combustion engine, weighted average is performed on the similarity of each parameter, and the result is determined as the similarity between the gas internal combustion engine and the candidate gas internal combustion engine. In practical application, the description information of the gas internal combustion engine can be taken as a model input, the combined gas internal combustion engine is taken as a model output, a classification model is trained, and the description information of the candidate gas internal combustion engine is input into the trained classification model, so that whether the corresponding energy station is the combined gas internal combustion engine is determined.

The joint model can be constructed specifically by the following 2 implementation modes:
in the implementation mode 1, aiming at each joint learning client, when the difference of a plurality of gas internal combustion engines in a joint energy station corresponding to the joint learning client is large, the joint learning client performs joint learning based on respective model training data sets of a plurality of joint gas internal combustion engines stored in the joint learning client to obtain a local pollution index monitoring model, and when a plurality of gas internal combustion engines in the joint energy station corresponding to the joint learning client are similar, the joint learning client performs joint learning based on respective model training data sets of all the gas internal combustion engines stored in the joint learning client to obtain a local pollution index monitoring model; the local pollution index monitoring models corresponding to the combined learning clients are obtained, the combined pollution index monitoring model is built based on the local pollution index monitoring models corresponding to the combined learning clients, and compared with one local model corresponding to each combined gas internal combustion engine, the calculation amount can be reduced, and the calculation efficiency is improved.
In the implementation mode 2, for each combined gas internal combustion engine, the local pollution index monitoring model is obtained by performing combined learning based on the model training data set of the combined gas internal combustion engine, the local pollution index monitoring model corresponding to each of the plurality of combined gas internal combustion engines is obtained, and the combined model is built based on the local pollution index monitoring model corresponding to each of the plurality of combined gas internal combustion engines.
And step 204, sending the pollution index monitoring model to the application client so that the application client can determine the pollution index data of the gas internal combustion engine according to the pollution index monitoring model.
The pollution index monitoring model may be understood as a model which is input as operation data of the gas internal combustion engine and output as pollution index data, for example, may be a neural network, a support vector machine, a lifting decision tree, etc., and it should be understood that the present embodiment is not intended to limit the internal structure of the pollution index monitoring model, and any model which can take operation data of the gas internal combustion engine as input and pollution index data as output is applicable to the present embodiment.
