All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a method for acquiring and analyzing environmental data in a tunnel, including:
s101: and determining the data acquisition device arranged in the tunnel.
S102: and acquiring first environment data and first vehicle state data in the tunnel through the data acquisition device.
The data collecting device may be classified into an environmental data collecting device (e.g., a brightness sensor, a temperature sensor, a humidity sensor, a wind sensor, etc.) and a vehicle state collecting device (e.g., a camera). The number of each type of data acquisition device may be plural.
The data acquisition device is used for acquiring data, so that first environment data (such as brightness, temperature, humidity and wind power) and first vehicle state data (such as traffic flow) can be obtained, and the first vehicle state data can be analyzed based on the traffic flow besides the traffic flow, so that other data, such as tail gas emission data, vehicle lamp data and the like, can be obtained.
S103: and analyzing the first environment data and the first vehicle state data respectively to obtain corresponding environment curves and vehicle state curves.
When the environmental curve corresponds to multiple dimensions (e.g., multiple dimensions of brightness, temperature, humidity, wind, etc.), the environmental curve may be multiple. Similarly, the vehicle state curve may also be multiple. And the curve may be obtained by collecting corresponding data over a period of time.
S104: and generating a corresponding mapping relation according to the environment curve and the vehicle state curve.
The mapping relationship refers to a corresponding change in the environmental curve when the vehicle state curve changes. Of course, not the change of the vehicle state curve, but the change of the environment curves of all dimensions is caused, so that the curve of a part of dimensions can be selected from the environment curves to generate the mapping relation.
S105: and acquiring a change curve of the external environment data within a specified time in the future, and performing adaptive adjustment on the first environment data according to the change curve to obtain second environment data.
The variation curve of the environmental data over a specified time period in the future can be obtained by an associated weather system, such as a weather forecast system. When the outside changes, the inside of the tunnel also changes, and at this time, the first environment data in the tunnel is adaptively adjusted.
S106: and compensating the second environmental data according to the mapping relation and the estimated vehicle state data in the specified duration to obtain third environmental data.
In addition to the change of the outside world, the mapping relationship is obtained, which shows that the vehicle state data can also influence the internal environment data, so that the vehicle state data in the specified time duration is estimated, the vehicle state data is compensated through the mapping relationship, and the third environment data is finally obtained, wherein the third environment data is finally obtained as the environment data in the tunnel in the future specified time duration, and at the moment, the equipment in the tunnel can be pre-adjusted according to the third environment data.
In one embodiment, when acquiring the first environment data and the first vehicle state data, the acquired data transmitted by the data acquisition device may be received first, then the identifier of the data acquisition device is determined, and the type of data acquired by the data acquisition device, such as luminance data, temperature data, image data, etc., is determined according to the identifier.
According to the data type, the acquired data is correspondingly preprocessed to obtain preprocessed data, for example, the image data is subjected to noise reduction processing and the like. And regarding each data acquisition device, taking all the preprocessed data corresponding to the data acquisition device as a sample set to obtain the sample sets corresponding to the data acquisition devices respectively. Each sample set includes only the plurality of data collected by the data collection device. And obtaining a data cleaning model through sample set training, and performing data cleaning on the preprocessed data according to the data cleaning model to obtain cleaning data. The cleaned data can be used for screening out abnormal data. And dividing the cleaning data into first environment data and first vehicle state data according to the data types corresponding to the cleaning data.
Further, the specific process of data cleansing may include: and generating corresponding labels for the sample set according to the data types corresponding to the sample set, wherein one label can be generated by one data type. And selecting a plurality of sample sets from all sample sets in the same label, training the sample sets as training sets to obtain a data cleaning model corresponding to the label, and verifying the data cleaning model by using the rest sample sets as verification sets. Each tag may train a data cleansing model. And screening out the preprocessed data of which the verification result in the verification set does not meet the preset requirement. Thus, data cleaning in the verification set is completed. And repeating the data cleaning process of the data cleaning model, and reselecting the training set and the verification set in each repeating process. Thus, all sample sets can be subjected to data cleaning.
In one embodiment, when the mapping relationship is generated, first, for an environment curve corresponding to each dimension, a curve trend corresponding to the environment curve is determined, and a curve trend corresponding to a vehicle state curve is determined. The curve trend includes at least one of a speed increase, an inflection point, and an extremum, and the curve trend can be reflected by these values.
Then, the similarity of the curve trend of the vehicle state curve and the curve trend among the environment curves is determined, and the environment curves corresponding to the dimensions with the similarity exceeding a first preset similarity (for example, 80%) and the similarity lower than a second preset similarity (for example, 20%) are selected, wherein the first preset similarity is higher than the second preset similarity. The curve with high similarity indicates that the two are in positive correlation, while the curve with low similarity indicates that the two are in negative correlation, which indicates that the two are usually in a certain relationship. For example, the more vehicles, the more exhaust gas is discharged, and the tunnel is a relatively closed space, so the temperature inside the tunnel also rises. At this time, a corresponding mapping relation is generated according to the selected environment curve and the vehicle state curve.
In an embodiment, when the first environment data is adaptively adjusted, the tunnel may be divided into a plurality of paragraphs, where the plurality of paragraphs at least include a middle paragraph, an entrance paragraph (including an exit paragraph and an entrance paragraph). In general, the external environment affects the entrance and exit sections more than the middle section. Therefore, at this time, the first environment data corresponding to the plurality of paragraphs can be respectively adjusted adaptively according to the variation curve to obtain the second environment data corresponding to the plurality of paragraphs, wherein the adjustment range of the middle paragraph is smaller than the adjustment range of the entrance paragraph. In this case, the second environment data corresponding to the tunnel may be obtained by summarizing the second environment data of the plurality of paragraphs.
In one embodiment, in predicting future vehicle state data, a time period corresponding to a specified future time period and a date corresponding to the time period may be determined first. And then, estimating the traffic flow in the specified time period according to the time period, for example, if the time period is a peak in the morning and evening, the traffic flow is higher. And compensating the estimated result according to the date, for example, the traffic flow of the morning and evening peaks of the weekend is smaller than the traffic flow at ordinary times. And estimating the vehicle state data in the specified time according to the compensated traffic flow. For example, the traffic flow may be regarded as vehicle state data, and exhaust emission, vehicle lamp brightness, and the like may be determined according to the traffic flow for prediction.
