The brightness of the image meets the brightness requirements of the data analysis end when analyzing the video image.

The data collection terminal 102 is used to collect and store the detection data of the chemical site in real time, and send the detection data to the data analysis terminal in real time.

The above is a description of the data collection terminal 102 from a functional point of view. The data collection terminal is used to collect the detection data on the chemical site and send it to the data analysis terminal, so as to provide a data basis for the data analysis terminal to analyze the abnormal situation in the chemical field. and exist.

The chemical on-site testing data refers to various testing data recorded in the presence of chemicals, including environmental testing data, experimental data, etc.; chemical on-site testing data can reflect the state of chemicals, according to preset The numerical changes of the detection data during the time period are used to determine whether there is an abnormality in the chemical. The explanation about the chemical scene has already been explained at the video capture end 101, and will not be repeated here.

The real-time collection and storage of chemical on-site detection data means that in order to completely record the factors that affect the chemical on-site physical and chemical properties of the chemical, the data collection terminal periodically collects the chemical on-site detection data according to a preset time, which is convenient for The data analysis terminal determines the influencing factors of abnormal conditions at the chemical site by analyzing the changes in the detection data. Among them, the time interval for the data collection terminal to collect the detection data will be designed according to the specific chemical characteristics, which is not limited here.

In the present application, the data collection terminal realizes the one-way transmission of the collected data to the outside through a one-way gateway. That is to say, the detection data provided by the data collection end to the data analysis end is one-way transmission, and the data analysis end will not transmit data to the data collection end. The data collection terminal includes at least one data collection device, and the application does not limit the number of data collection devices.

The data analysis terminal 103 is used to analyze the abnormal state, including analyzing the video image and the detection data, and when an abnormal situation is found, generating and uploading an alarm data file from the relevant detection data and the relevant video image.

The data analysis terminal obtains relevant detection data and relevant video images of abnormal situations by analyzing the video images collected by the video collection terminal and the detection data collected by the data collection terminal, and generates and uploads alarm data files for the safety supervision of chemical sites. Provide early warning information.

The abnormal situation refers to the data whose detected data does not belong to the normal range value of the corresponding data, for example, the detected data is larger or smaller than its preset data threshold; or the video image has images with different display phenomena from the normal scene situation, for example, A flame phenomenon appears in the video image.

When the data analysis terminal analyzes the abnormal state, it can analyze and judge the detection data and the video image to obtain the abnormal state of the chemical site. When the data analysis end analyzes that the detection data is larger or smaller than its preset data threshold, and makes a comprehensive judgment based on the video images of the time period when the detection data appears, when the judgment result is abnormal, the relevant detection data and relevant video images will generate an alarm The data file is uploaded; when the data analysis terminal analyzes the video image that shows different display phenomena from the normal scene, the video image is abnormal, and then retrieves the detection data corresponding to the video image for comprehensive judgment, when the judgment result belongs to In the event of an abnormal situation, the relevant detection data and relevant video images will be generated and uploaded to the alarm data file.

As can be seen from the above description, in order to obtain the abnormal situation in the chemical field, the data analysis terminal of the present application obtains the abnormal situation by analyzing the detection data and video images respectively. Therefore, the data analysis terminal described in this application adopts different analysis methods for detection data and video images to obtain abnormal conditions. 2 and 3 are respectively described in detail below.

Please refer to FIG. 2, which provides a flowchart of the abnormal situation found by the data analysis terminal by analyzing and detecting data. The processing steps are as follows:

Step S101: Classify the detection data to obtain data of various types of detection data within a preset time period.

In this step, the data analysis terminal is used to collect statistics on various types of detection data within a preset time period, so as to provide a data basis for subsequent analysis of the data.

The classification of detection data refers to classification according to data attributes, for example, environmental data, including: temperature data, humidity data, visibility data, etc.; process parameter data, including: voltage data, current data, liquid level data, etc.; chemical reaction Data, including: flammable gas data, toxic gas data, etc.

Classifying the detection data to obtain data of various types of detection data within a preset time period refers to classifying various types of detection data according to data attributes, and dividing all data of each type of detection data within a preset time period , to prepare for the subsequent data analysis terminal to analyze and detect data to obtain abnormal data.

Step S102: According to the preset analysis method and parameters, analyze various types of detection data respectively, and perform comprehensive analysis in combination with different types of data to determine whether an abnormal situation occurs.

In this step, the data analysis terminal is used to analyze various types of detection data according to a preset analysis method to determine whether an abnormal situation occurs.

The preset analysis method refers to analyzing and judging detection data under abnormal conditions from various types of detection data. In general, the preset analysis method adopts the variance calculation method. First, the variance value of all the data of each type of detection data within the preset time period is calculated, and then combined with the variance values of different types of detection data, a comprehensive analysis is performed to determine Whether an exception occurs.

In addition, the preset analysis method can also preset a data threshold range in which various types of detection data belong to a normal situation. If it exists, comprehensive analysis is carried out in combination with other types of detection data that exceed the specified threshold range to determine whether there is an abnormal situation. In addition, other preset methods may also be used in this step to analyze and determine whether there is an abnormality in the detection data, which is not limited in this application.

It is determined by the above method that there is an abnormality in the detection data, the data analysis terminal further retrieves the video images of the time period where the detection data is located, and further combines the video images to comprehensively analyze whether there is an abnormality phenomenon, and finally compare the relevant detection data with the The video image corresponding to the detection data generates an alarm data file and uploads it.

The above is the step operation method for the data analysis end to find abnormal situations by analyzing and detecting data. Correspondingly, the data analysis terminal can also find abnormal situations by analyzing the video images.

Please refer to FIG. 3 , which provides a flowchart of the abnormal situation found by the data analysis terminal by analyzing the video image. The processing steps are as follows:

Step S201: Provide the video image to a pre-trained safety state video recognition system for safety state recognition; the safety state video recognition system is an intelligent image recognition system obtained through pre-training, and the intelligent recognition system can read the video image by reading the video image. , to determine whether there is an abnormal situation.

In this step, it is judged whether the video image provided by the video acquisition terminal is abnormal in the security state video recognition system.

The safety state video recognition system refers to a video recognition system for judging whether there is an abnormality in a video image, and the safety state video recognition system is obtained by training a deep learning model. Before the data analysis end provides the video image to the safety state video recognition system for safety recognition, the safety state video recognition system obtains in advance possible abnormal conditions on the chemical site through a deep learning model. The specific learning method includes: providing the video images marked as "normal" state and the video images marked as "abnormal" state in advance to the safety state video recognition system set up by the principle of deep learning, for the safety state video recognition system training. .

In the training process, the labeled video images can be divided into two parts, one part is used as training data, and the other part is used as verification data; the training data is provided to the security state video recognition system for parameter adjustment, and finally adjusted to be able to The two video images are accurately identified, and the training data is large enough to enable the safety state video recognition system; after the parameters are adjusted, the verification data can be provided to the safety state video recognition system, the safety state The video recognition system recognizes the verification data, determines whether it is in an "abnormal" state, and then compares it with the previous annotation to determine whether the recognition result is accurate. Using the above method, the trained safety state video recognition system can be scored. If the score is passed, the safety state video recognition system can be used. The safety status video recognition system may also be a multi-classification system, that is, not only to identify whether the image is abnormal, but also to identify the type of abnormality. The specific training process is similar to the above description.

The essence of the work of the security state video recognition system is to recognize specific features of images, which belongs to the field of image recognition. The technology is relatively mature at present, and there are many specific deep learning models that can be used, which will not be repeated here.

The security state video recognition system can be included in the data analysis terminal, and can also be independent of the data analysis terminal. When detecting the video image, the data analysis terminal transmits the video image to the system through the network.

Step S202: According to the safety state identification result of the safety state identification system, determine whether there is an abnormal situation in the video image.

This step is used to determine whether there is an abnormality in the video image.

The safety status identification result of the safety status video identification system refers to the result of identifying the video image using the safety status video identification system described in step S201, and the specific determination details refer to the description in step S201.

The above is the specific operation description for the data analysis end to find the abnormal situation by analyzing the video image. If the data analysis end finds the abnormal situation in the video image, it determines the relevant time period of the detection data according to the type of the abnormal situation, and obtains The detection data within this time period is used as the relevant detection data. In other words, after analyzing the video image to find the abnormal situation, the data analysis end will combine the detection data of the relevant time period of the video image to comprehensively analyze the video image and related detection data to determine whether it is an abnormal situation. Images and associated inspection data generate alarm data files. The relevant time period refers to the time period determined according to the type of abnormal situation that may be related to this type of abnormal situation; for example, if a combustion abnormality occurs, it can be considered to retrieve the temperature detection data from one minute before the image was generated to the current time ; If abnormal gas escape occurs, the current pressure detection data from 5 minutes before the image is retrieved.

The above Figures 2 and 3 respectively describe the specific operation steps of the data analysis terminal to find the abnormal situation of the chemical site by analyzing the detection data and the video image respectively.

Wherein, when analyzing the current detection data or the current video image, the data analysis terminal will also perform comparative analysis with historical data.

The data analysis terminal is also used to generate a real-time data file from the detection data and the video image corresponding to the detection data and store it as historical data; when performing the abnormal state analysis, it includes the data related to the historical data. comparative analysis.

The detection data provided by the data acquisition terminal and the video image provided by the video acquisition terminal include time information for recording the detection data and the video image, and a corresponding relationship is established between the detection data and the video image according to the time information. When the data analysis terminal receives the detection data and the video image, it generates a real-time data file from the detection data and the video image corresponding to the detection data according to the time information, and stores it as historical data, so as to provide historical data for the data analysis terminal to perform abnormal state analysis. Data base. In addition, when the data analysis terminal performs abnormal state analysis, it will not only analyze and compare with historical data, but also conduct comprehensive analysis in combination with the basic data pre-entered by the data analysis terminal.

In addition, the data analysis terminal also includes an abnormal state evaluation model, and the abnormal state evaluation model is used to analyze the production data information of the chemical site, as follows:

The data analysis terminal is specifically used to obtain the production data information of the chemical site, input the production data information of the chemical site into the abnormal state evaluation model, and obtain the output of the abnormal state evaluation model and the chemical product. The abnormal state alarm level information corresponding to the on-site production data information.

It should be noted that the production data information of the chemical site includes at least one kind of data information among video data information of the chemical site and detection data information of the chemical site.

It should be noted that the abnormal state evaluation model is pre-trained according to historical production data information and historical production data abnormal state alarm levels corresponding to the historical production data information. Specifically, the abnormal state evaluation model includes a video data abnormal state evaluation model and a detection data abnormal state evaluation model. The abnormal state evaluation model of video data is pre-trained based on historical video data information and the alarm level of historical video data abnormal state corresponding to the historical video data; The abnormal state alarm level of historical detection data is pre-trained.

Specifically, the abnormal state evaluation model includes a smoke abnormal state evaluation model and a water mist abnormal state evaluation model. For example, if there is flame and smoke in the video image detected by the video status monitoring terminal, the data analysis terminal will obtain the video data including the flame and smoke, input the abnormal status evaluation model of the video data, and obtain the output of the abnormal status evaluation model of the video data. The alarm level of the abnormal state of the video data corresponding to the video data of the flame and smoke. Among them, the degree of flame and smoke in the video image has a corresponding relationship with the alarm level of the abnormal state of the video data. For example, if a first-level flame, that is, a small flame, belongs to a medium-sized abnormal state, the alarm level of the abnormal video state is one. Level 1 alarm, which means that it is necessary to stop the experiment on the chemical site, and to detect and repair the location where the first level smoke appears on the chemical site. If what appears in the image is a secondary flame, that is, a large flame and dense fog, which is a severe abnormal state, the alarm level of the abnormal video state is a secondary alarm, which means that it is necessary to urgently stop the chemical on-site experiment and carry out emergency handling. .

Secondly, the data analysis terminal is also used to judge whether the duration of the abnormal state of the chemical site corresponding to the abnormal state alarm level information is greater than the preset time threshold; if the above judgment result is yes, then the abnormal state Alarm level information, the production data information of the chemical site corresponding to the abnormal state alarm level information is taken as a negative sample; if the above judgment result is no, the abnormal state alarm level information and the abnormal state alarm The production data information of the chemical site corresponding to the grade information is taken as a positive sample; the abnormal state evaluation model is trained according to the positive sample and the negative sample.

Specifically, for example, when the data analysis end receives a video image sent by the video acquisition end, a first-class flame appears, and the data analysis end inputs the above video data into the video data abnormal state evaluation model, and the abnormal state output of the video data abnormal state evaluation model is abnormal. Status alarm level information is a first-level alarm. After the preset time, the data analysis end inputs the video image data collected by the video acquisition end into the video data abnormal state evaluation model. The output result of the video data abnormal state evaluation model shows that the first-level alarm disappears, indicating that the sample is a positive sample. . If after the preset time, the output result of the abnormal state evaluation model of video data in the data analysis terminal is still a first-level alarm, it means that there is an error in the evaluation and analysis of the video image data of the video acquisition terminal by the abnormal video data evaluation model, and it is not practical. It represents the actual situation of the chemical site, therefore, this sample is a negative sample. According to a large number of positive samples and negative samples, the abnormal state evaluation model is trained and optimized to improve the evaluation accuracy of the abnormal state evaluation model.

Chemicals provide the data base.

The equipment parameter input terminal 103-2 is used to input equipment parameters of the equipment involved in the chemical storage and use process.

The equipment parameters of the equipment involved in the chemical storage and use process are the equipment adjustment parameter ranges required by the chemical, which are set according to the basic physical and chemical properties of the chemical; different chemicals have different physical and chemical properties, Therefore, according to the basic physicochemical properties of the chemical, the equipment should adjust the equipment parameters corresponding to the characteristics of the chemical.

The chemical data input terminal 103-3 is used for inputting the data of raw chemicals and the data of intermediate chemicals generated in the chemical processing process.

At least one intermediate chemical is produced. Therefore, the chemical data entry terminal needs to record the data of raw chemicals and intermediate chemicals, and record the chemical synthesis principle.
