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.
FIG. 1 shows a system for monitoring reaction in a converter steelmaking process, which comprises: a lens group 110, a snapshot-type spectral imaging chip 120, and a data processing device 130;

the data processing device 130 is configured to receive the spectral image, perform spectral analysis on the spectral image, and monitor a reaction state in the furnace according to a result of the spectral analysis.
Considering that the traditional image sensor can only collect the image information of the flame at the furnace mouth, the image information only comprises three channels of red, green and blue, and further accurate analysis of the image is very difficult. The method is an effective technical means for accurately measuring and monitoring the reaction condition in the furnace in a non-contact manner at present. The main reason is that different chemical reactions can produce different substances and different substances can produce different spectrums, so that the spectrum can be analyzed to more accurately analyze the conditions of the reaction in the furnace, thereby monitoring the reaction process of converter steelmaking.
However, in the converter steelmaking process, the flame smoke dust at the furnace mouth is more and the distribution is uneven, if the commercial spectrometer is used for measurement, the commercial spectrometer can only obtain spectrum information of a single point, so the commercial spectrometer is very easy to be interfered by the smoke dust, the obtained spectrum information is inaccurate, the difficulty is brought to the follow-up analysis of the spectrum to monitor the reaction condition in the furnace, and the commercial spectrometer has large volume and high cost and is not strong in practicability for monitoring the reaction in the converter steelmaking process.
Accordingly, the embodiment adopts the snapshot type spectrum imaging chip as a device for collecting spectrum images, the snapshot type spectrum imaging chip is a device for measuring spectrum by utilizing modulation actions of different micro-nano structures, and the snapshot type spectrum imaging chip can be used for obtaining spectrum information in the whole area of an image. Meanwhile, the snapshot spectrum imaging chip has the advantages of high imaging speed, small size, low cost and the like. Therefore, the snapshot type spectrum imaging chip is used for detecting the spectrum image of the flame area of the furnace mouth during converter steelmaking, and the area to be analyzed, namely the area which is not interfered by smoke dust, is selected for analysis, so that accurate spectrum information can be obtained, and the reaction condition in the furnace can be accurately analyzed.
Specifically, referring to fig. 2, the snapshot-type spectral imaging chip 120 mainly includes a photosensitive modulator 210 and an image sensor 220;

It should be noted that, the photosensitive modulator 210 mainly refers to a portion of the snapshot spectrum imaging chip 120 formed by stacking the micro-nano modulation structure on the photosensitive layer and having photosensitive and light modulation functions.
Because the photographic function of the snapshot spectrum imaging chip 120 itself has higher requirements on the distance of the measured object, spectrum images need to be acquired in a shorter distance, in order to realize the monitoring of the flame at the remote furnace mouth, the embodiment is additionally provided with the lens group 110, the lens group 110 is installed at the front end of the quick illumination spectrum imaging chip 120, corresponds to the photographic area, a plurality of lenses exist in the lens group 110, and can cooperate with the snapshot spectrum imaging chip 120 to realize the spectrum image acquisition effect with the same quality or even higher quality at the position farther from the converter mouth.
In an exemplary embodiment, referring to fig. 3, the data processing apparatus 130 may employ a monitoring computer 310, where the monitoring computer 310 is configured to receive the electrical signal, perform a spectral restoration process on the electrical signal, perform a spectral analysis on a spectral image obtained by the spectral restoration process, and monitor a reaction state in the furnace according to a result of the spectral analysis.

In another exemplary embodiment, referring to fig. 4, the data processing device 130 may also be implemented by using a processing module 410 and a monitoring terminal 420 in cooperation, where the processing module 410 is integrated on the snapshot spectrum imaging chip 120;
the processing module 410 is configured to receive the electrical signal, perform spectrum restoration processing on the electrical signal, and perform spectrum analysis on a spectrum image obtained by the spectrum restoration processing to obtain a spectrum analysis result;
the monitoring terminal 420 is used for monitoring the reaction state in the furnace according to the spectrum analysis result.
In this embodiment, the spectrum image processing function and the state monitoring function are respectively allocated to the processing module 410 and the monitoring terminal 420, where the processing module 410 may be understood as a built-in computing module added on the snapshot spectrum chip 120, and may implement functions such as spectrum image recovery and spectrum analysis, and the reaction state information in the furnace obtained by spectrum analysis is displayed by the monitoring terminal 420, and the monitoring terminal 420 may be understood as a display with a display function, or may also be implemented by an intelligent terminal such as a computer with a display function.
In an exemplary embodiment, the data processing device 130 may extract a region, which is not interfered by smoke dust, in the spectrum image according to the brightness of the fire hole flame in the spectrum image, and perform spectrum analysis on the region, which is not interfered by smoke dust, so as to avoid the influence of smoke dust interference on the spectrum analysis precision, and ensure that the spectrum analysis process is more efficient and accurate.
It should be noted that, the data processing device 130 is specifically configured to receive the spectral image, perform spectral analysis on the spectral image, and perform early warning on the abnormal reaction state in the furnace according to the result of the spectral analysis.
In order to realize the discrimination of the abnormal reaction state, the embodiment firstly acquires the spectral images of the flame at the furnace mouth in the whole flow of converter steelmaking, analyzes the spectral characteristics of each spectral image, marks the reaction state in the furnace corresponding to each spectral image, and mainly analyzes the spectral characteristic information of the spectral image before the abnormal reaction state occurs, and marks the abnormal reaction state of the spectral image before the abnormal reaction state occurs, thereby obtaining a spectral image data set.
And training a pre-constructed neural network model by utilizing the spectral image data set to obtain a spectral analysis model, and inputting a spectral image of the actually measured flame at the furnace mouth into the spectral analysis model in practical application to obtain the furnace reaction state information output by the spectral analysis model, so that the current furnace reaction state can be determined, and the output abnormal state is early-warned.
In the practical application process, the lens group 110 and the snapshot spectrum imaging chip 120 can be integrally designed in one camera, the lens group 110 is a lens part of the camera, and the snapshot spectrum imaging chip 120 is arranged in the body of the camera, so that a spectrum image of flame at a furnace mouth is remotely observed, in an actual steelmaking site, the lens group 110 and the snapshot spectrum imaging chip 120 can be placed at a position about 20m in front of a converter and right against the furnace mouth, remote spectrum image acquisition is realized, and the service life influence and acquisition precision interference of a severe environment near the converter on the lens group 110 and the snapshot spectrum imaging chip 120 are also reduced to a certain extent.
Finally, the reaction state information and the early warning information in the furnace output by the data processing device 130 can be displayed at the remote end in real time, and of course, other early warning modes, such as a mode of setting an audible and visual alarm on site, pushing the early warning information to a mobile terminal of a manager and the like, can be set reasonably according to actual requirements, and are not repeated here too much.
It is not difficult to find that the in-furnace reaction monitoring system for the converter steelmaking process provided by the embodiment of the invention can realize long-distance rapid acquisition of the spectral image of the flame at the furnace mouth through the cooperation of the lens group and the snapshot type spectral imaging chip, and meanwhile, can realize automatic monitoring of the in-furnace reaction state through cooperation of the data processing equipment, is more convenient in monitoring process, is more accurate in monitoring data, is more real-time, and is more suitable for modern converter steelmaking application scenes.
The method for monitoring the reaction in the converter steelmaking process provided by the embodiment of the invention is described below, and the system for monitoring the reaction in the converter steelmaking process is needed to be used in the process of monitoring the reaction state in the converter steelmaking process.
FIG. 5 shows that the invention provides a method for monitoring the reaction in a converter steelmaking process, which comprises the following steps:

and monitoring the reaction state in the furnace according to the reaction state information in the furnace.
It can be understood that, in this embodiment, the spectral analysis model obtained by training in advance performs spectral analysis on the region to be analyzed in the spectral image, so as to obtain the reaction state information in the furnace, thereby conveniently obtaining the reaction state information in the furnace.
In this embodiment, the process for obtaining the sample data for training the spectral analysis model, that is, the spectral image data set marked with the information of the reaction state in the furnace, may include:
firstly, a spectrum image sample of the flame at the furnace mouth in the whole steelmaking process of the converter is obtained, and a whole steelmaking process image set is constructed.
And then, respectively determining the areas which are not interfered by smoke dust in each spectrum image sample in the whole steelmaking image set according to the brightness of the flame at the furnace mouth.
Considering that the areas interfered by the smoke and the areas not interfered by the smoke are different in brightness of the flame at the furnace mouth, namely different in light intensity, the areas which are not interfered by the smoke and the dust in the spectrum image can be found by determining the brightest areas of the flame at the furnace mouth, so that the influence of the smoke and the dust interference on the analysis result of the spectrum can be avoided, and the accuracy of the subsequent spectrum analysis can be improved.

And finally, respectively marking the spectral characteristic information and the in-furnace reaction state information corresponding to each spectral image sample, and secondarily marking the spectral image samples in a preset period when the abnormal reaction state in the furnace occurs and before the abnormal reaction state occurs to obtain a spectral image data set.
In the process of labeling, after labeling the reaction state label corresponding to each spectrum image sample, the embodiment can extract the spectrum image sample of the corresponding furnace mouth flame and the corresponding spectrum characteristic in a certain period of time when and immediately before the abnormal reaction state in the furnace, and the spectrum image sample in the period of time is subjected to emphasis labeling (namely secondary labeling), so that the spectrum analysis model can accurately predict the abnormal reaction state in the furnace.
In this embodiment, the abnormal reaction state in the furnace mainly refers to molten steel splashing, and the molten steel splashing may cause explosion of the converter when the molten steel splashing is serious in the steelmaking process of the converter, so that the marking of the abnormal reaction state of the molten steel splashing can improve the discrimination capability of a spectral analysis model obtained by post training on the molten steel splashing.
