Detailed Description
Some embodiments of the invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention.

A module may comprise hardware circuitry, various suitable sensors, communication ports, memory, or software components, such as program code, or a combination of software and hardware. The processor may be a central processor, a microprocessor, an image processor, a digital signal processor, or any other suitable processor. The processor has data and/or signal processing functions. The processor may be implemented in software, hardware, or a combination of both. Non-transitory computer readable storage media include any suitable medium that can store program code, such as magnetic disks, hard disks, optical disks, flash memory, read-only memory, random access memory, and the like. The term "a and/or B" means all possible combinations of a and B, such as a alone, B alone or a and B. The term "at least one A or B" or "at least one of A and B" has a meaning similar to "A and/or B" and may include A alone, B alone or A and B. The singular forms "a", "an" and "the" include plural referents.
Referring to fig. 1, fig. 1 is a schematic flow chart of main steps of a model training method according to an embodiment of the present invention. As shown in fig. 1, the model training method in the embodiment of the present invention mainly includes the following steps S101 to S103.
Step S101: historical temperature data for a plurality of gearboxes of a train is collected.
In this embodiment, historical temperature data of a plurality of gearboxes provided on a train may be collected. For example, 32 gearboxes are provided on a train, possibly distributed in different cars.
In one embodiment, historical temperature data for 32 gearboxes a day may be acquired, with data acquired twice a day for each gearbox, i.e., 64 historical temperature data are obtained in total. The 64 historical temperature data may be divided into 32 groups based on the gearbox identification carried by the historical temperature data, one group for each gearbox.
In one embodiment, the historical temperature data for the gearbox may be obtained based on temperature sensor testing provided on the gearbox.
Step S102: for each gearbox of the train, at least one other gearbox that has an effect on the current gearbox is determined.
In this embodiment, at least one other gearbox having an effect on each gearbox may be obtained.
In one embodiment, the effect may be an electromagnetic effect. If the distance between the gear box a and the gear box B is relatively short, the gear box B may have an electromagnetic effect on the gear box a. It should be noted that the influence of the gear box B on the gear box a does not represent that the gear box a also has an influence on the gear box B; possible influences on the gearbox B are the gearbox C and the gearbox D.
In another embodiment, the effect may be a mechanical effect, for example, each gearbox may have a mechanical effect on other gearboxes when one produces a mechanical offset due to a mechanical connection.
In one embodiment, at least one other gearbox having an impact on the current gearbox may be determined according to a preset rule.
In one example, it may be measured through preliminary experimentation whether each gearbox (e.g., a) on the train is electromagnetically disturbed by the other gearboxes (e.g., greater than a certain threshold, such as the electromagnetic disturbance of gearboxes B and C to gearbox a being greater than the threshold), and if so, the disturbing gearboxes B and C will be factors affecting gearbox a (i.e., preset rules regarding gearbox a). Of course, the preset rule can also be obtained by electromagnetic simulation of the gearbox on the train through electromagnetic modeling simulation software. For the example of the mechanical influence described above, the preset rule may be determined by mechanical modeling simulation software such as ANSYS, FEM, for example.
The preset rules can be written in a configuration file, and other gearboxes with influence on the current gearboxes can be determined through the configuration file. A person skilled in the art can compile preset rules according to the needs of practical application and write the preset rules into a configuration file to obtain other gearboxes having influence on the current gearboxes.
Step S103: based on the historical temperature data of other gearboxes and the historical temperature data of the current gearboxes, training the linear regression model corresponding to the current gearboxes to obtain a trained linear regression model corresponding to each gearbox.
In this embodiment, the linear regression model corresponding to the current gearbox may be trained according to historical temperature data of the current gearbox and other gearboxes having an influence on the current gearbox, so as to obtain a trained linear regression model. Since the effects of the gearboxes are not symmetrically matched (gearbox B has an effect on gearbox A and does not represent that gearbox A will have an effect on gearbox B; gearbox B may have an effect on gearbox C and gearbox D), the steps are repeated to obtain respective linear regression models for all gearboxes on the train.
In one embodiment, step S103 may further include the following steps S1031 and S1032:
step S1031: a training set of the current gearbox is constructed based on historical temperature data of other gearboxes and historical temperature data of the current gearbox.
In the present embodiment, step S1031 may further include the following steps S10311 to S10313:
step S10311: the historical temperature data of other gearboxes are taken as a characteristic column.
Step S10312: the historical temperature data of the current gear box is taken as a target column.
Step S10313: based on the feature columns and the target columns, feature engineering is constructed as a training set of the current gearbox.
In this embodiment, the feature engineering may be constructed by using the historical temperature data of the other gear boxes as a feature column and the historical temperature data of the current gear box as a target column, so as to construct the training set based on the feature engineering. For example, 32 gearboxes, the training set constructed correspondingly is 32 groups. The feature engineering refers to a process of converting original data into features which better express the nature of a problem, so that the application of the features to a prediction model can improve model prediction accuracy of invisible data. The targets are labels or targets in the machine learning process. The feature columns are data in the training set other than the target columns in the machine learning process.
Step S1032: and training a linear regression model corresponding to the current gear box according to the training set of the current gear box.
In this embodiment, the training set of the current gearbox may be applied to train the linear regression model corresponding to the current gearbox, so as to obtain a trained linear regression model.
Based on the steps S101-S103, the embodiment of the present invention collects historical temperature data of a plurality of gearboxes of a train, determines that other gearboxes are affected for each gearbox, trains a corresponding linear regression model based on the historical temperature data of each gearbox and the other gearboxes with the affects, and thus obtains a trained linear regression model, and based on the trained linear regression model, can obtain a predicted value of the current temperature of the gearboxes, thereby realizing prediction of the current temperature of the gearboxes. Through the configuration mode, the embodiment of the invention can predict the current temperature of the current gear box based on the temperature affecting other gear boxes, can more accurately reflect the accurate temperature of the gear box, and effectively avoid the problem that the normal operation of a train is affected when detecting equipment such as a temperature sensor on the gear box has faults.
Furthermore, the invention also provides a temperature prediction method of the gear box.
Referring to fig. 2, fig. 2 is a schematic flow chart of main steps of a temperature prediction method of a gearbox according to an embodiment of the invention. As shown in fig. 2, the temperature prediction method of the gearbox in the embodiment of the present invention mainly includes the following steps S201 to S203.
Step S201: current temperature measurement data of a plurality of gearboxes of a train is acquired.
In this embodiment, current temperature measurement data of a plurality of gearboxes provided on a train may be acquired.
In one embodiment, a temperature sensor is provided on the gearbox. The current temperature measurement data may be obtained by a temperature sensor provided on each gear.
Step S202: for each gear box, current temperature measurement data of other gear boxes with influence on the current gear box are input into a linear regression model corresponding to the current gear box, and a current temperature predicted value of the current gear box is obtained; wherein the linear regression model is obtained according to the model training method described in the model training method embodiment above.
In this embodiment, the current temperature measurement data of other gearboxes having an influence on each gearbox may be input into the corresponding trained linear regression model, so as to obtain the current temperature predicted value of the gearbox. The linear regression model corresponding to each gear box is obtained by training based on the model training method described in the embodiment of the model training method.
In one embodiment, the current temperature measurement data of other gearboxes that have an effect on each gearbox may be retrieved through a preset profile. The configuration file may be written according to a preset rule. The preset rule may be a rule written according to influence, and a person skilled in the art may set the preset rule according to the needs of the actual application.
An example, the effect may be an electromagnetic effect. For example, electromagnetic effects may exist when two gearboxes are relatively close together.
Step S203: and obtaining a temperature prediction result of each gear box according to the current temperature measurement data and the current temperature prediction value of each gear box.
In this embodiment, the temperature prediction result of each gear case may be obtained from the current temperature measurement data of the gear case and the current temperature prediction value obtained based on the linear regression model.
In one embodiment, step S203 may further include the following steps S2031 and S2032:
step S2031: the current temperature measurement data is compared to the current temperature prediction value.
In the present embodiment, the current temperature measurement data obtained by the temperature sensor measurement may be compared with the current temperature prediction value predicted by the linear regression model for each gear case.
Step S2032: and obtaining a temperature prediction result according to the comparison result.
In the present embodiment, the temperature prediction result may be obtained based on the comparison result.
In one embodiment, if the comparison result is that the difference between the current temperature measurement data and the current temperature predicted value is large (for example, greater than a preset threshold value), it may be considered that the temperature sensor of the corresponding gearbox is abnormal, so that operations such as maintenance and the like may be performed on the temperature sensor.
In one embodiment, if the comparison result is that the difference between the current temperature measurement data and the current temperature predicted value is large (for example, greater than a preset threshold value), the measurement of the temperature sensor of the corresponding gearbox may be considered to be inaccurate, and then the linear regression model may be applied to obtain the current temperature predicted value as the final temperature predicted result of the gearbox.
In one embodiment, if the comparison result is that the difference between the current temperature measurement data and the current temperature predicted value is smaller (for example, smaller than or equal to the preset threshold value), the temperature sensor measurement of the corresponding gearbox can be considered to be accurate, and the current temperature measurement data measured by the temperature sensor can be directly applied as the final temperature predicted result of the gearbox.
Based on the steps S201-S203, the embodiment of the invention can predict the current temperature of the current gear box based on the temperature affecting other gear boxes, can more accurately reflect the accurate temperature of the gear box, and effectively avoid the problem that the normal operation of the train is affected when the detection equipment such as the temperature sensor on the gear box has faults.
