Description

Technical Field

[0001] This invention relates to the field of safety technology, and in particular to a method, device, fusion map, and storage medium for generating a safety risk emergency evacuation fusion map. Background Technology

[0002] In current enterprise safety management practices, safety risk four-color distribution maps and emergency evacuation maps are typically drawn and displayed as two separate charts. When employees need to understand both risk distribution and evacuation routes, they must consult both types of maps separately, leading to low information acquisition efficiency and redundant waste of management resources. Furthermore, existing safety risk four-color maps lack standardized formats, and the correlation between risk indicators and key emergency evacuation information is weak. This separation of charts fails to meet the actual needs of rapid emergency response. Therefore, how to efficiently integrate safety risk information and emergency evacuation guidelines onto a single chart, forming an intuitive and unified visualization tool, thereby solving the technical problems of low information acquisition efficiency and slow emergency response caused by chart separation, has become an urgent problem to be solved in this field. Summary of the Invention

[0003] This application provides a method, device, fusion map, and storage medium for generating a safety risk emergency evacuation fusion map. This solves the technical problem in the prior art where safety risk maps and emergency evacuation maps are independent and information is fragmented, resulting in low information acquisition efficiency for practitioners and slow emergency response. It achieves deep fusion and visualization of risk and evacuation information on a single map, significantly improving the intuitive perception of the safety situation and the efficiency of emergency decision-making.

Based on the accident statistics, personnel density distribution characteristics, and severity of consequences indicators corresponding to each safety risk factor, the actual risk level corresponding to each safety risk factor is determined.

[0006] Furthermore, based on the accident statistics, personnel density distribution characteristics, and consequence severity index data corresponding to each safety risk factor, the actual risk level corresponding to each safety risk factor is determined, including: Based on the accident statistics corresponding to each safety risk factor, determine the accident probability index parameters; Based on the personnel density distribution characteristics corresponding to each safety risk factor, determine the personnel exposure frequency index parameters; Based on the severity index data of the consequences corresponding to each safety risk factor, determine the parameter for the number of casualties; Based on the accident probability index parameters, personnel exposure frequency index parameters, and personnel casualty quantity index parameters corresponding to each safety risk factor, the actual risk level corresponding to each safety risk factor is determined.

[0007] Further, obtaining the functional zoning plan of the target floor includes: Obtain the original functional zoning diagram of the target floor; The original functional zoning diagram is adjusted according to the preset drawing rules to obtain the floor plan functional zoning diagram of the target floor.

[0009] Furthermore, after obtaining the safety risk emergency evacuation fusion map, the method further includes: Based on the target location to be displayed corresponding to the safety risk emergency evacuation fusion map and the observer's viewing angle of the target location, an observer location marker corresponding to the target location is drawn in the safety risk emergency evacuation fusion map.

[0010] Furthermore, after obtaining the safety risk emergency evacuation fusion map, the method further includes: According to the preset production rules, a physical fusion diagram matching the aforementioned safety risk emergency evacuation fusion diagram is produced using phosphorescent materials.

Detailed Implementation

[0017] This application provides a method for generating a safety risk emergency evacuation fusion map, which solves the technical problem in the prior art where the safety risk map and the emergency evacuation map are independent and information is fragmented, resulting in low information acquisition efficiency for practitioners and slow emergency response.

[0018] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows: This application embodiment establishes a comprehensive and structured data foundation by systematically collecting and integrating multi-source heterogeneous data, fundamentally solving the problem of information silos. Furthermore, it introduces a multi-dimensional quantitative assessment model, transforming descriptive risk factors into precise risk levels, significantly improving the scientific rigor and objectivity of risk assessment. By mapping risk levels to standard color identifiers, it provides an intuitive visual encoding of the spatial distribution of risks. The established precise correspondence between risks and evacuation factors and spatial locations ensures that all information elements are accurately represented on the map. Finally, based on preset rules, automated graphic synthesis generates a fused map integrating the four-color risk distribution and emergency evacuation guidance. Therefore, this application embodiment transforms previously fragmented safety management and emergency response information into a unified, standardized, and visualized decision support map through a coherent and automated process. This fundamentally solves the core problems of low information acquisition efficiency and slow emergency response caused by the separation of charts and graphs, achieving an improvement from scattered data to integrated, visualized, and intelligent management.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] First, it should be clarified that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0021] This application provides a method for generating a safety risk emergency evacuation fusion map, the method including steps S11-S15, which can be referred to... Figure 1 As shown.

[0022] Step S11: Obtain the various safety risk factors contained in the target floor, the floor plan of the target floor, and the various emergency evacuation factors contained in the target floor; Step S12: Assess the risk level of each safety risk factor to obtain the actual risk level corresponding to each safety risk factor; Step S13: Based on the actual risk level corresponding to each safety risk factor and the correspondence between the risk level and the color code, determine the target color corresponding to each safety risk factor; Step S14: Determine the first correspondence between various safety risk factors and the functional zones in the planar functional zoning diagram, and determine the second correspondence between various emergency evacuation factors and the functional zones in the planar functional zoning diagram; Step S15: Based on the first correspondence, the second correspondence, and the preset drawing rules, draw the target colors corresponding to various safety risk factors and various emergency evacuation factors in the planar functional zoning diagram to obtain a safety risk emergency evacuation fusion diagram.

[0023] The method for generating a safety risk emergency evacuation fusion map provided in this application embodiment can be executed by an electronic device with data processing and graphics display functions, such as a server, desktop computer, laptop computer, tablet computer, or dedicated emergency command terminal.

[0024] Regarding step S11, obtain the various safety risk factors contained in the target floor, the floor plan of the target floor, and the various emergency evacuation factors contained in the target floor.

[0025] Multiple safety risk factors encompass all sources and conditions within the target floor that could potentially lead to safety accidents. For example, this could include the distribution of occupational hazard factors, referring to physical, chemical, or biological factors present in specific functional areas that may cause occupational diseases, such as noise, dust, and toxic gases; it could also include confined space locations, referring to areas with narrow entrances and exits, poor ventilation, and unsuitable for prolonged work, such as the interiors of storage tanks, reactors, and underground pipelines, which pose extremely high risks in emergency situations; and it could include safe operating procedures, which, although not physical entities, are mandatory safety regulations that must be followed in specific areas (such as when operating a hazardous piece of equipment), and are important safety management factors.

[0026] Multiple emergency evacuation factors encompass facilities and routes used for evacuation, rescue, and initial response in emergency situations. Specifically, these include: evacuation routes—pre-planned main escape routes leading to safe exits; emergency equipment locations—fixed storage points for supplies such as fire extinguishers, fire hydrants, emergency lighting, eyewash stations, and first-aid kits; and emergency response procedures—initial response guidelines for specific areas or risks (such as chemical spills or fires).

[0027] The floor plan of the target floor serves as the geographical foundation for integrating all information. It is not simply a building outline, but a workshop layout that divides different areas according to actual use. For example, it needs to clearly mark production areas, storage areas, office areas, main passages, entrances and exits, etc., thus providing a spatial framework for accurately matching safety and evacuation elements to their corresponding locations.

[0028] Step S11 involves the collection and integration of multi-source data. Specifically, Step S11 systematically collects and aggregates various heterogeneous data by connecting to the enterprise's existing safety management database, forming a unified "basic data pool." First, it acquires safety risk data describing "where the danger lies," including the distribution points of occupational hazard factors derived from risk identification, the precise locations of confined spaces, and related safety operating procedures. Second, it acquires emergency evacuation data indicating "how to respond," mainly including pre-planned evacuation routes, distribution records of various emergency equipment, and key emergency response procedures. Finally, a functional zoning map, serving as the spatial carrier, is acquired, becoming the geographical foundation upon which all abstract information is ultimately implemented. Step S11 effectively breaks down and integrates data silos previously scattered across multiple management departments such as safety, occupational health, and fire protection, providing comprehensive and structured data support for subsequent risk assessment and visualization integration.

[0029] Further, obtaining the floor plan of the target floor includes: obtaining the original floor plan of the target floor; adjusting the original floor plan according to the preset drawing rules to obtain the floor plan of the target floor.

[0030] First, obtain the original functional zoning plan of the target floor from the building or facilities management department. This plan typically contains basic spatial structure and zoning information. Then, adjust this original plan according to the preset drawing rules. This adjustment process involves a series of key standardization steps, the core purpose of which is to ensure the clarity, readability, and consistency of the final base map, in accordance with the drawing specifications for emergency evacuation and safety signage.

[0031] The adjustment process, which involves setting up pre-defined drawing rules, may include: standardizing line widths by differentiating line thicknesses based on the structural importance of the facilities; for example, setting load-bearing wall lines to 1.6mm, partition wall lines to 0.6mm, and detail element lines to as thin as 0.15mm. Simultaneously, standardizing text annotations in the drawings by using boldface fonts for both Chinese and English, and specifying minimum heights (3mm for Chinese, 2mm for English) to ensure easy readability under any lighting conditions. Furthermore, the background color of the drawing should be white or phosphorescent white; the latter allows for self-illumination in emergency situations such as power outages, ensuring the continued usability of the drawing information. Through this series of meticulous standardization operations, the final floor plan of the target floor is obtained. This plan not only accurately reflects the spatial layout but also serves as a standardized base map optimized for subsequent overlay of dynamic risk and evacuation information, conforming to professional standards.

[0032] Regarding step S12, the risk level of each safety risk factor is assessed to obtain the actual risk level corresponding to each safety risk factor.

[0033] Step S12 is the core processing step in generating the fusion diagram. Its function is to transform the descriptive "safety risk factors" obtained in step S11 into quantifiable and visually coded "actual risk levels." Specifically, step S12 does not perform preliminary risk identification, but rather, based on the identified risk factors, uses a multi-dimensional, scientific assessment model to accurately assign a risk level to each factor (such as specific equipment, chemicals, or work areas) that may lead to an accident.

[0034] Furthermore, step S12 may include steps S1211-S1212.

[0035] Step S1211: Obtain the accident statistics data corresponding to the industry where the functional area of ​​each safety risk factor is located in the functional zoning diagram, the personnel density distribution characteristics of each safety risk factor corresponding to the functional area of ​​the functional zoning diagram, and the consequence severity index data corresponding to each safety risk factor. Step S1212: Based on the accident statistics, personnel density distribution characteristics, and severity of consequences indicators corresponding to each safety risk factor, determine the actual risk level corresponding to each safety risk factor.

[0036] Okay, based on the previous discussion, we will provide a detailed explanation and refinement of steps S1211 and S1212.

[0037] Step S1211 is the data preparation stage for risk assessment. Its core lies in collecting three key types of quantitative or qualitative input data for each identified safety risk factor (such as the specific hazard source obtained in S11), thereby providing a basis for subsequent accurate calculations. Specifically: Accident statistics: This data is used to measure the probability of an accident occurring. The system will obtain statistical values ​​of the frequency of accidents under similar equipment, processes, or operating environments from authoritative industry databases or enterprise historical records, based on the industry type corresponding to the functional area where the risk factor is located (e.g., chemical, machinery processing, warehousing and logistics), to provide an objective benchmark for assessing the "probability of accident occurrence".

[0038] Personnel density distribution characteristics: This data is used to measure the frequency and scale of personnel exposure to risks. The system analyzes the personnel distribution in target functional areas during typical working hours (e.g., whether it is a high-density area with fixed positions or a low-frequency inspection route), which directly affects the range of personnel that may be affected in the event of an accident.

[0039] Consequence Severity Index Data: This data is used to measure the severity of the harm that an accident may cause. The system will obtain preset consequence simulations or historical case data for this risk factor. Its main indicator is the estimated number of casualties, which is used to determine the final impact level of the accident.

[0040] Step S1212 integrates the multi-dimensional data acquired in S1211 into a unified assessment model, thereby outputting a quantified actual risk level. This step is not a simple comparison, but rather a comprehensive calculation of the three dimensions using a built-in risk matrix or calculation algorithm that conforms to industry safety standards. Specifically, it uses accident statistics reflecting "probability," personnel density distribution characteristics reflecting "exposure," and consequence severity indicators reflecting "severity" as input parameters. Through model calculation, the system generates a comprehensive risk value for each safety risk factor and accurately classifies it into its corresponding "actual risk level" based on a preset risk level classification standard (e.g., levels I, II, III, and IV from high to low). For example, a risk factor that is common in the chemical industry (high accident statistics), located in a densely populated area (high personnel density), and capable of causing serious injuries (high severity) will be assessed at the highest level (e.g., level I) and thus marked with the most prominent color (e.g., red) in the subsequent fusion diagram.

[0041] Furthermore, step S12 may also include steps S1221-S1224.

[0042] Step S1221: Determine the accident probability index parameters based on the accident statistics data corresponding to each safety risk factor; Step S1222: Determine the personnel exposure frequency index parameters based on the personnel density distribution characteristics corresponding to each safety risk factor; Step S1223: Based on the severity index data of the consequences corresponding to each safety risk factor, determine the parameter for the number of casualties; Step S1224: Based on the accident probability index parameter, personnel exposure frequency index parameter, and personnel casualty quantity index parameter corresponding to each safety risk factor, determine the actual risk level corresponding to each safety risk factor.

[0043] The core of step S1221 lies in transforming macro-level industry accident statistics into a quantitative indicator of the probability of occurrence for that specific risk factor. Specifically, the system does not directly use raw statistics, but rather maps them to a standardized "accident probability" level based on the historical accident frequency of the industry, equipment type, or operational nature (e.g., the average number of accidents per million hours for a certain equipment in the chemical industry) through a built-in conversion or lookup table rule. For example, the frequency can be divided into several distinct levels such as "extremely unlikely," "possible," and "very likely," or converted into a calculable numerical score, thus providing a unified and comparable input parameter for subsequent comprehensive calculations regarding the "probability of occurrence."

[0044] Step S1222 aims to quantify the extent to which personnel are within the risk's impact zone. The system analyzes personnel distribution data for the functional area where the risk factor is located. This includes analyzing whether personnel are engaged in long-term, fixed work (such as production line positions), scheduled inspections, or occasional visits. Based on this analysis, the system transforms the qualitative distribution characteristics into a standardized "personnel exposure frequency" level or parameter. For example, areas with "fixed positions, high density" are rated as "continuous exposure," areas with "several inspections per day" are rated as "frequent exposure," and areas with "occasional weekly visits" are rated as "occasional exposure." This parameter ensures that the assessment focuses not only on the incident itself but also on the "opportunity for personnel impact."

[0045] Step S1223 quantifies and classifies the worst-case scenario consequences. Based on the risk factor's attributes (such as hazardous chemical reserves, equipment pressure, and working height) and existing safety analysis, the system estimates the potential number of casualties if the situation gets out of control. Then, according to preset consequence grading standards (e.g., 1-2 minor injuries, 3-10 serious injuries, or multiple deaths), this estimated number is mapped to a standardized "consequence severity" level or parameter. This step ensures that the assessment can distinguish between risks that may result in minor incidents and risks that may lead to major accidents.

[0046] Step S1224 uses a pre-defined, industry-standard (e.g., risk matrix) assessment model to comprehensively calculate the three-dimensional parameters output from the first three steps. This model defines the final risk level corresponding to different combinations of the three parameters. For example, a risk that is "very likely" to occur, subject to "continuous exposure," and has "serious" consequences is comprehensively determined to be at the highest level (e.g., Level I). Through this systematic, multi-factor coupled decision-making logic, this method ensures the scientific, objective, and consistent nature of risk level classification, providing a core basis for generating an accurate and reliable four-color fusion chart.

[0047] Regarding step S13, based on the actual risk level corresponding to each safety risk factor and the correspondence between the risk level and the color code, the target color corresponding to each safety risk factor is determined.

[0048] Step S13 transforms the abstract "actual risk level" of each safety risk factor (such as Level I, Level II, Level III, etc. obtained from the assessment) into an intuitive visual signal, namely "target color", through a pre-set, standardized mapping system.

[0049] Specifically, the system internally stores or invokes a clear correspondence between risk levels and color codes. This correspondence typically follows industry consensus or national recommended standards. For example, the highest risk level (Level I) is mapped to red, representing prohibition, danger, and major risks requiring immediate attention; a higher risk level (Level II) is mapped to orange, representing warnings and significant risks requiring control measures; a medium risk level (Level III) is mapped to yellow, representing reminders and general risks requiring attention; and a low risk level (Level IV) is mapped to blue, representing notification and alerts.

[0050] Through this step, each numerical or graded risk assessment conclusion calculated in step S12 is uniquely and accurately assigned a specific color code. This provides a precise coloring basis for the next step of visual rendering on the planar functional zoning map to generate the final, easily understandable "four-color safety risk map" layer, achieving a qualitative leap from data to graphics.

[0051] Regarding step S14, a first correspondence is determined between various safety risk factors and the functional zones in the planar functional zoning diagram, and a second correspondence is determined between various emergency evacuation factors and the functional zones in the planar functional zoning diagram.

[0052] Step S14 involves establishing a precise link between abstract security management elements and specific physical spatial locations.

[0053] First, the system establishes the initial correspondence between various safety risk factors and the functional zones in the functional zoning diagram. This process aims to address the question of "where are the risks?" The system treats each safety risk factor (such as occupational hazard factors, confined spaces, etc.) obtained in step S11 as an independent object, and uses its physical location information to precisely associate and bind it to specific areas in the functional zoning diagram (such as "Production Line 1 Area," "Class A Chemical Warehouse," and "East Passage on the Third Floor"). For example, the system uniquely corresponds the hazard source "High-Temperature Reactor" and its assessed risk level to the area representing its exact location on the diagram, thus laying the foundation for subsequently coloring that area with the corresponding risk color.

[0054] Secondly, the system determines the second correspondence between various emergency evacuation factors and the functional zones in the aforementioned functional zoning plan. This process aims to address the question of "where are the emergency facilities and routes?" The system also associates the emergency evacuation factors (such as evacuation routes, fire extinguishers, fire hydrants, emergency assembly points, etc.) obtained in step S11 with their precise locations on the base map, based on their actual placement. For example, an "evacuation route" will be associated with all the passages and exits it passes through; a "fire extinguisher" will be associated with the zone where the wall or column it is mounted on is located.

[0055] By establishing these "first correspondence" and "second correspondence," this method assigns clear spatial geographic coordinates (location) to all non-spatial attribute safety management data (what risks, what equipment), realizing the transformation of information management from list-based to layer-based management, and providing an indispensable spatial data foundation for ultimately integrating all elements into a unified plan.

[0056] Regarding step S15, based on the first correspondence, the second correspondence, and the preset drawing rules, the target colors corresponding to various safety risk factors and various emergency evacuation factors are drawn on the planar functional zoning map to obtain a safety risk emergency evacuation fusion map.

[0057] Step S15, as an automated drawing engine, works based on three key inputs: the first correspondence (which indicates the specific location of each risk factor on the base map), the second correspondence (which indicates the specific location of each emergency evacuation factor on the base map), and the preset drawing rules (which define the visual presentation standards of all graphic elements).

[0058] The specific execution process is as follows: First, based on the first correspondence, the system accurately draws the target color (determined by step S13) corresponding to each safety risk factor onto its bound functional area using a region-filling method, thus forming an intuitive four-color risk distribution layer. Next, based on the second correspondence and preset drawing rules, the system overlays various emergency evacuation factors (such as evacuation routes, emergency equipment icons, etc.) onto the same base map. The preset drawing rules can be set according to relevant regulations or actual needs. They specify in detail, for example, the use of specific line types (such as green dashed lines) to mark evacuation routes, the use of standardized symbols to indicate the location of fire extinguishers or fire hydrants, and ensure that the size and style of all icons and text (such as boldface fonts and minimum font size in Chinese and English) conform to specifications, guaranteeing the clarity, consistency, and professionalism of the entire drawing.

[0059] Through this layered drawing and synthesis, step S15 finally yields a safety risk emergency evacuation fusion map that integrates static spatial layout, dynamic risk level, and key emergency guidelines, successfully unifying scattered multi-source information into a standard visualization interface.

[0060] In summary, this application's embodiments, through the systematic collection and integration of multi-source heterogeneous data, lay a comprehensive and structured data foundation, fundamentally solving the problem of information silos. Furthermore, the introduction of a multi-dimensional quantitative assessment model transforms descriptive risk factors into precise risk levels, significantly improving the scientific rigor and objectivity of risk assessment. By mapping risk levels to standard color identifiers, an intuitive visual encoding of the spatial distribution of risks is provided. The established precise correspondence between risks and evacuation factors and spatial locations ensures that all information elements are accurately represented on the map. Finally, automated graphic synthesis based on preset rules generates a fused map integrating the four-color risk distribution and emergency evacuation guidance. It is evident that this application's embodiments transform previously fragmented safety management and emergency response information into a unified, standardized, and visualized decision support map through a coherent and automated process. This fundamentally solves the core problems of low information acquisition efficiency and slow emergency response caused by the separation of charts and graphs, achieving an improvement from scattered data to integrated, visualized, and intelligent management.

[0061] Furthermore, after obtaining the safety risk emergency evacuation fusion map, the method also includes steps S21-S22.

[0062] Step S21: Monitor whether any one of the following data in the target floor—safety risk factors, floor plan functional zoning, and emergency evacuation factors—has been updated; Step S22: If any one of the data of safety risk factors, floor plan functional zoning diagram and emergency evacuation factors in the target floor is updated, the multiple safety risk factors, floor plan functional zoning diagram and emergency evacuation factors contained in the target floor are reacquired, and a safety risk emergency evacuation fusion diagram is regenerated based on the reacquired multiple safety risk factors, floor plan functional zoning diagram and emergency evacuation factors.

[0063] Step S21 establishes a dynamic monitoring and data update triggering mechanism for the fusion diagram. Step S21 does not generate the image all at once, but rather continuously or periodically monitors whether any data constituting the core data model of the fusion diagram in the target floor has been updated through system interfaces or data probes. This specifically includes: monitoring changes in safety risk factors (such as the addition of equipment, changes in hazardous chemical reserves, or updates to risk identification results), monitoring changes in the floor plan functional zoning (such as layout adjustments due to factory renovations), and monitoring changes in emergency evacuation factors (such as replanning evacuation routes, relocation or addition / deletion of emergency equipment). This mechanism ensures that the system can perceive changes in the physical world or management decisions in real time, providing precise event trigger signals for the dynamic updating of the fusion diagram.

[0064] Step S22 defines the closed-loop update and automatic reconstruction process of the fused diagram. Once step S21 detects an update to any data, the system immediately triggers this process. If any of the data related to safety risk factors, floor plan functional zoning, or emergency evacuation factors in the target floor is updated, the system will reacquire all relevant latest data, including the various safety risk factors, floor plan functional zoning, and emergency evacuation factors contained in the target floor. Subsequently, based on this reacquired and updated data, the system will automatically initiate and execute the complete generation process from risk assessment (step S12) to diagram fusion (step S15), regenerating the safety risk and emergency evacuation fused diagram. This step fundamentally ensures the synchronization of the fused diagram with the real environment and safety management status, upgrading it from a static display diagram to a "living" digital twin that can dynamically evolve with actual conditions, continuously providing accurate and reliable visual evidence for emergency decision-making.

[0065] Furthermore, after obtaining the safety risk emergency evacuation fusion map, the method further includes: Based on the target location to be displayed corresponding to the safety risk emergency evacuation fusion map and the observer's viewing angle of the target location, an observer location marker corresponding to the target location is drawn in the safety risk emergency evacuation fusion map.

[0066] After obtaining the safety risk emergency evacuation fusion map, this application embodiment enhances its practical guidance value in emergency scenarios. Specifically, based on the target location to be displayed corresponding to the safety risk emergency evacuation fusion map (e.g., the specific corridor or workshop area where the drawing is planned to be hung) and the typical observation perspective of an observer looking at the target location, this application embodiment dynamically draws an observer location marker corresponding to the target location on the map. This function establishes an intuitive self-positioning and spatial orientation reference system for the user by prominently marking an "You are here" icon or viewpoint origin on the map and combining it with the observation direction. This improvement effectively solves the orientation confusion that people may experience when facing complex or large-scale floor plans, enabling them to quickly match the drawing information with their own real-world environment, thereby greatly shortening the information understanding and decision-making time, further improving the efficiency and practicality of the fusion map in on-site guidance during emergency situations, transforming it from a general static drawing into a dynamic guidance tool with clear on-site guidance functions.

[0067] Furthermore, after obtaining the safety risk emergency evacuation fusion map, the method further includes: According to the preset production rules, a physical fusion diagram matching the aforementioned safety risk emergency evacuation fusion diagram is produced using phosphorescent materials.

[0068] After obtaining the emergency evacuation fusion map for safety risks, this embodiment transforms the digitized fusion map into a physical entity with emergency practical value. Specifically, the pre-defined production rules clearly stipulate the material selection, printing process, and installation specifications, with the core requirement being the use of phosphorescent (luminescent) materials as the printing medium for the main body or key elements of the map. This technical choice ensures that the resulting physical fusion map is indistinguishable from ordinary drawings under normal lighting conditions. However, in emergency situations such as power outages or dense smoke causing a sharp decrease in visibility, the map can autonomously emit continuous cold light based on pre-absorbed light energy, ensuring that key information such as risk zone colors, evacuation route arrows, emergency equipment icons, and "You are here" remains clearly identifiable in the dark. This improvement fundamentally solves the fatal flaw of traditional evacuation maps being unreadable due to lighting failure at critical moments, greatly enhancing the reliability and robustness of the emergency evacuation system, and realizing the final step in the transformation from an ideal digital solution to reliable physical emergency equipment.

[0069] The embodiments of this application are now combined with Figure 2 The following specific example is provided to illustrate a method for generating a safety risk emergency evacuation fusion map according to an embodiment of this application.

[0070] The study covered all functional areas on the first floor of the ironworks restaurant, including the kitchen (operating area, main stove, pastry area), storage areas (vegetable storage, non-staple food storage, staple food storage, and general merchandise storage), changing rooms, bathrooms, cold storage, elevators, small dining area, lobby, duty room, equipment room, and restrooms—a total of 11 areas. The LEC (Likelihood-Frequency-Severity) method was used for quantitative analysis, with the following scoring criteria: Probability (L): 10 (completely predictable) - 0.1 (actually impossible), assigned based on statistics of accidents in the catering industry over the past 5 years.

[0071] Exposure frequency (E): 10 (continuous exposure) — 0.5 (rare exposure), categorized by daily work hours and personnel density.

[0072] Severity of consequences (C): 100 (10 or more deaths) - 1 (minor impact), quantified according to relevant regulations on production safety accident reporting and investigation.

[0073] Risk level: D = L × E × C, divided into major risk (D > 320), significant risk (160 ≤ D ≤ 320), moderate risk (70 ≤ D ≤ 160), and low risk (0 ≤ D ≤ 70). The risk level of each safety risk factor is assessed to obtain the actual risk level corresponding to each safety risk factor. See the assessment table below for different functional areas.

[0074] 1. Kitchen area Table 1

[0075] 2. Warehouse area Table 2

[0076] 3. Cold storage area Table 3

[0077] 4. Elevator area Table 4

[0078] 5. Changing rooms and bathrooms Table 5

[0079] 6. Small dining room and foyer Table 6

[0080] 7. Duty room and equipment room Table 7

[0081] 8. Toilet Table 8

[0082] Risks with D > 320 are considered major risks: elevator overload and fall (D = 400) are characterized by "low probability and devastating consequences" because once an elevator shaft falls, the survival rate is almost zero (refer to historical shopping mall elevator fall accidents).

[0083] Risk points with a value of 160≤D≤320 are considered as major risk items: including three items, namely kitchen flue fire (D=270), gas leak (D=240), and electrical fire in equipment room (D=300). They share the common characteristics of rapid spread of accidents and wide impact range, requiring 24-hour monitoring.

[0084] Risk points with 70≤D≤160 are classified as general risk items: a total of 10 items, mainly concentrated in mechanical injuries (knife cutting, door clamping), suffocation (people trapped in cold storage), stampedes (crowding in small restaurants), etc., mostly caused by human error, requiring strengthened training and on-site management.

[0085] Risk points with a risk level of 20≤D≤70 are classified as low-risk items: there are 9 items in total, mainly minor injuries and property losses, such as theft of items and collisions with glass doors, which can be gradually improved through daily inspections.

[0086] Then, based on the actual risk level corresponding to each safety risk factor in the table above and the correspondence between the risk level and the color code, the target color corresponding to each safety risk factor is determined.

[0087] Based on the first correspondence between various safety risk factors and the functional zones in the planar functional zoning diagram, the second correspondence between various emergency evacuation factors and the functional zones in the planar functional zoning diagram, and preset drawing rules, the target colors corresponding to various safety risk factors and various emergency evacuation factors are drawn in the planar functional zoning diagram, resulting in the following: Figure 2 The diagram shown is a fusion diagram of emergency evacuation for safety risks.

[0088] In summary, this embodiment of the application effectively solves the problem of separate drawings in traditional management by integrating the four-color safety risk map with the emergency evacuation map into a single map. This achieves unified information display, reducing resource waste from redundant production and significantly improving the efficiency of personnel in obtaining critical information in emergency situations. Secondly, by adopting standardized drawing rules to unify and standardize the lines, text, background colors, and other elements of the integrated map, the standardization and immediate readability of the map are ensured in different application scenarios, while also flexibly adapting to the customized needs of different locations. Finally, by introducing a dynamic update module and linking it with the enterprise's existing information system, real-time monitoring of changes in risk factors and emergency elements and automatic synchronous updates of the map are achieved, forming real-time collaboration between risk monitoring and emergency response. This fundamentally improves the enterprise's proactive safety early warning capabilities and dynamic risk management level.
