[0022] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0023] In view of the above problems in the prior art, the present invention provides a method for determining a fire extinguishing strategy for a chemical industrial park. Figure 1 It is a schematic flowchart of a method for determining a fire extinguishing strategy for a chemical industrial park provided by the present invention. As Figure 1 shown, the method includes the following steps 110, 120 and 130.

[0024] Step 110: Obtain the text of the fire situation of the chemical industrial park input by the user, and the key influencing factors corresponding to the text of the fire situation.

[0025] Specifically, in the event of a fire in a chemical industrial park, the user can input the text of the fire situation in the chemical industrial park. The execution entity of the present invention can obtain the text of the fire situation, which may include: (1) a fire occurs in a general building; (2) a fire occurs in a chemical storage tank and there is no chemical medium in the chemical storage tank; (3) a fire occurs in a chemical storage tank and there is a chemical medium in the chemical storage tank. When determining the fire extinguishing strategy subsequently, the fire extinguishing strategies corresponding to different fire situation texts may be different. For example, for a fire in a general building, ordinary fire trucks can be used, while for a fire in a chemical storage tank, large-flow fire trucks such as Williams are required.

[0026] In one embodiment, the key influencing factors include fire fighting force, chemical storage tank type, and wind speed and direction data; Obtaining the key influencing factors corresponding to the text of the fire situation includes: Determining the fire fighting force and the chemical storage tank type based on the fire truck positioning information and the management data corresponding to the chemical industrial park; Obtaining the wind speed and direction data corresponding to the chemical industrial park from the weather system.

[0027] Specifically, the key influencing factors corresponding to the text of the fire situation in the chemical industrial park can also be obtained. The key influencing factors include fire fighting force, chemical storage tank type, and wind speed and direction data. The fire fighting force and the chemical storage tank type can be determined based on the fire truck positioning information and the management data corresponding to the chemical industrial park. The fire fighting force can be, for example, the number of available fire trucks in the area where the chemical industrial park is located. The wind speed and direction data corresponding to the chemical industrial park can also be obtained from the weather system. The wind speed and direction data can, for example, characterize the wind speed and direction in the area where the chemical industrial park is located within a preset future time period.

[0028] In the above embodiment, the fire fighting force and the chemical storage tank type are determined based on the fire truck positioning information and the management data corresponding to the chemical industrial park, and the wind speed and direction data corresponding to the chemical industrial park are obtained from the weather system. Combining the three types of data, namely the fire fighting force, the chemical storage tank type, and the wind speed and direction data, can more accurately determine the fire extinguishing strategy.

[0029] Step 120: Determine the disaster situation word segmentation result and the strategy word segmentation result based on the text of the fire situation and the key influencing factors.

[0030] In one embodiment, the disaster situation word segmentation result includes multiple disaster situation words and their respective corresponding word segmentation types, and the strategy word segmentation result includes multiple strategy words and their respective corresponding word segmentation types; The determining the disaster situation word segmentation result and the strategy word segmentation result based on the text of the fire situation and the key influencing factors includes: Based on the fire situation text and the key influencing factors, determine the initial fire extinguishing strategy according to the preset expert rules, and splice the fire situation text, the key influencing factors, and the initial fire extinguishing strategy into a disaster situation and strategy statement; Perform word segmentation on the disaster situation and strategy statement to obtain each disaster situation word segment and each strategy word segment corresponding to the disaster situation and strategy statement; Determine the word segment types corresponding to each of the disaster situation word segments respectively, and determine the word segment types corresponding to each of the strategy word segments respectively.

[0031] Specifically, the disaster situation word segmentation result includes multiple disaster situation word segments and the word segment types corresponding to each of the multiple disaster situation word segments respectively, as well as multiple strategy word segments and the word segment types corresponding to each of the multiple strategy word segments respectively. The initial fire extinguishing strategy can be determined based on the fire situation text and the key influencing factors according to the preset expert rules. The preset expert rules can be represented by the following formula: Wherein, represents the th fire extinguishing strategy; represents the prerequisite conditions corresponding to the th initial fire extinguishing strategy, that is, the fire situation text and the key influencing factors, represents the number of prerequisite conditions, represents the total number of rules in the preset expert rules, represents if XX then execute XX.

[0032] Furthermore, after determining the initial fire extinguishing strategy, the fire situation text, the key influencing factors, and the initial fire extinguishing strategy can be spliced into a disaster situation and strategy statement. The disaster situation and strategy statement can be, for example: "When a fire breaks out in a vault tank containing crude oil and there is a southeast wind, 2 large-flow fire extinguishing equipment should be deployed at the upwind position". Then, word segmentation can be performed on this disaster situation and strategy statement to obtain each disaster situation word segment and each strategy word segment corresponding to the disaster situation and strategy statement. When performing word segmentation on the disaster situation and strategy statement, any one of the word segmentation methods based on string matching, word segmentation methods based on statistics and machine learning, and methods of realizing computer word segmentation by simulating human understanding of sentences can be used.

[0033] Furthermore, the word segment types corresponding to each of the disaster situation word segments respectively and the word segment types corresponding to each of the strategy word segments respectively can be determined by the pre-constructed expert rule library. The word segment types include entities, attribute information, conditional words, indicator words, and quantifiers. Exemplarily, based on the expert rule library, the word segment categories of "vault tank / fire extinguishing equipment / crude oil / southeast wind / large flow / upwind / deploy / when / should / 2 vehicles" are shown in Table 1 below: Table 1 Example Table of Word Segment Categories

[0034] Among them, the entity is the main body in the disaster situation and strategy statement, such as "dome tank", "fire extinguishing equipment", etc.; the attribute information is the attributes possessed by the entity, such as "crude oil", "southeast direction", "large flow rate", "upwind", "deployment", etc.; the conditional word is a certain condition for a certain state to occur, such as "when", "at that time"; the indicator word is the corresponding indicating action when a certain condition occurs, such as "should"; the quantifier is used to describe the quantity of the entity, such as "2 vehicles", etc.

[0035] In the above embodiment, the fire situation text, key influencing factors, and initial fire extinguishing strategy are spliced into the disaster situation and strategy statement, and the disaster situation and strategy statement are segmented to obtain each disaster situation segment word and each strategy segment word corresponding to the disaster situation and strategy statement, as well as the segment word type corresponding to the segment word, which can improve the efficiency of subsequent determination of the target fire extinguishing strategy.

[0036] In one embodiment, the segmenting of the disaster situation and strategy statement to obtain each disaster situation segment word and each strategy segment word corresponding to the disaster situation and strategy statement includes: Construct a directed acyclic graph corresponding to the disaster situation and strategy statement; Determine multiple initial segment words corresponding to the disaster situation and strategy statement according to the directed acyclic graph; Based on a preset common word library, splice the multiple initial segment words to obtain each disaster situation segment word and each strategy segment word corresponding to the disaster situation and strategy statement.

[0037] Specifically, the present invention can use the jieba algorithm to segment the disaster situation and strategy statement. The jieba algorithm is a widely used Chinese word segmentation tool, and the preset common word library can be set in advance according to needs. The present invention embodiment does not make specific limitations here. The set of each disaster situation segment word and each strategy segment word can be represented by the following formula: Among them, represents the th disaster situation segment word, represents the th strategy segment word, represents the quantity of disaster situation segment words, represents the quantity of strategy segment words.

[0038] Exemplarily, the disaster situation and strategy statement is: "When a dome tank filled with crude oil catches fire, with a southeast wind, 2 large-flow fire extinguishing equipment should be deployed at the upwind position", Figure 2 is a schematic diagram of the directed acyclic graph provided by the present invention. The directed acyclic graph constructed for the above disaster situation and strategy statement is as Figure 2As shown. Further, it can be determined that the multiple initial word segments corresponding to the disaster situation and the policy statement are: "When / a vault tank / is filled with / crude oil / a fire breaks out, / east / south / wind, / it should / be deployed / at the / upwind / position / with / 2 / large-flow / fire-fighting / equipment". Further, based on the preset common word library, it can be matched that "east / south / wind", "upwind", and "large-flow" are all integral words. Then, these three words are concatenated to obtain "southeast wind", "upwind", and "large flow". Finally, the disaster situation word segments are obtained: "When / a vault tank / is filled with / crude oil / a fire breaks out, / southeast wind,", and the policy word segments are obtained: "it should / be deployed / at the / upwind / position / with / 2 / large-flow / fire-fighting / equipment".

[0039] In the above embodiment, the jieba algorithm is used to segment the disaster situation and the policy statement, and each disaster situation word segment and each policy word segment corresponding to the disaster situation and the policy statement are obtained, laying a foundation for determining the target fire-fighting strategy subsequently.

[0040] Step 130: Based on the disaster situation word segment result and the policy word segment result, determine the target fire-fighting strategy for the chemical industrial park.

[0041] In one embodiment, the determining the target fire-fighting strategy for the chemical industrial park based on the disaster situation word segment result and the policy word segment result includes: For each of the disaster situation word segments, based on the disaster situation word segment and the word segment type corresponding to the disaster situation word segment, determine the membership degree of the influencing factor corresponding to the disaster situation word segment; the membership degree of the influencing factor represents the similarity of the disaster situation word segment to the key influencing factor; For each of the policy word segments, based on the policy word segment and the word segment type corresponding to the policy word segment, determine the membership degree of the fire-fighting strategy corresponding to the policy word segment; the membership degree of the fire-fighting strategy represents the similarity of the policy word segment to the initial fire-fighting strategy; Determine the target fire-fighting strategy based on all the membership degrees of the influencing factors and all the membership degrees of the fire-fighting strategies.

[0042] Specifically, for each disaster situation word segment, based on the disaster situation word segment and the word segment type corresponding to the disaster situation word segment, determine the membership degree of the influencing factor corresponding to the disaster situation word segment. The membership degree of the influencing factor represents the similarity of the disaster situation word segment to the key influencing factor. For each policy word segment, based on the policy word segment and the word segment type corresponding to the policy word segment, determine the membership degree of the fire-fighting strategy corresponding to the policy word segment. The membership degree of the fire-fighting strategy represents the similarity of the policy word segment to the initial fire-fighting strategy. Further, the target fire-fighting strategy can be determined based on all the membership degrees of the influencing factors and all the membership degrees of the fire-fighting strategies.

[0043] In the above embodiments, based on the similarity of the disaster situation word segmentation for the key influencing factors and the similarity of the strategy word segmentation for the initial fire extinguishing strategy, the target fire extinguishing strategy is determined, which can best adapt to the key influencing factors corresponding to the fire situation text in the chemical industrial park.

[0044] In one embodiment, the determining of the target fire extinguishing strategy based on all the membership degrees of the influencing factors and all the membership degrees of the fire extinguishing strategies includes: Determining an influencing factor fuzzy vector based on all the membership degrees of the influencing factors; Determining a fire extinguishing strategy vector based on all the membership degrees of the fire extinguishing strategies; Determining the target fire extinguishing strategy based on the influencing factor fuzzy vector, the fire extinguishing strategy vector, and a preset fire extinguishing strategy analysis matrix.

[0045] Specifically, an influencing factor fuzzy vector can be determined based on all the membership degrees of the influencing factors , and the influencing factor fuzzy vector can be represented by the following formula: where represents the membership degree of the th disaster situation word segmentation for the key influencing factor.

[0046] A fire extinguishing strategy vector can also be determined based on all the membership degrees of the fire extinguishing strategies , and the fire extinguishing strategy vector can be represented by the following formula: where represents the membership degree of the th strategy word segmentation for the initial fire extinguishing strategy.

[0047] Furthermore, the target fire extinguishing strategy can be determined based on the influencing factor fuzzy vector, the fire extinguishing strategy vector, and the preset fire extinguishing strategy analysis matrix , and the target fire extinguishing strategy can be represented by the following formula: where represents a fuzzy logic operator, which processes the relationships between various variables according to the rules of fuzzy mathematics. The fuzzy logic operator can be, for example, a fuzzy union operator; represents the preset fire extinguishing strategy analysis matrix, which reflects expert instructions and can be set according to needs in advance.

[0048] In the above embodiments, determining the target fire extinguishing strategy based on the influencing factor fuzzy vector, the fire extinguishing strategy vector, and the preset fire extinguishing strategy analysis matrix can provide scientific and reasonable fire extinguishing strategy suggestions for on-site commanders in the event of a fire, make the optimal scientific decision quickly in an emergency, and significantly improve the accuracy of fire extinguishing command and the overall rescue efficiency.
