[0056] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0057] 1. Obtain the building-related information of the target building. Understand the basic structure, materials, age, etc. of the building. The structure and materials of the building directly affect its performance in a fire, which helps to evaluate the fire resistance of the building. Obtain the relevant information of the electrical equipment of the target building, understand the status of the equipment, service life, whether there is overload, etc., so as to evaluate the condition of the electrical equipment, identify potential electrical fire risks, and help prevent electrical fires. Understanding the behavior and mobility of people in the building will help to formulate more effective evacuation plans and fire response strategies. Obtain and analyze the fire-fighting equipment related information and surrounding environment related information of the target building, and evaluate the completeness of the building's fire-fighting equipment and the safety of the surrounding environment. Comprehensively obtain various fire safety threat parameters to obtain a comprehensive and multi-dimensional building fire safety assessment parameter, which is not limited to a single risk and helps to formulate more accurate preventive measures. Based on the comprehensive fire safety threat parameters, judge the fire hazard situation and the degree of harm, and issue an alarm prompt to warn relevant personnel and departments in time so that they can take necessary preventive measures and give early warning before the fire occurs, which can greatly reduce the losses caused by the fire and protect people's lives and property.

[0058] 2. By analyzing the degree of overlap between normal personnel flow routes and emergency evacuation routes, the efficiency and safety of personnel evacuation in emergency situations are evaluated. A high degree of route overlap means that in an emergency, personnel can identify and transfer to the evacuation route more quickly, reducing the difficulty of evacuation and improving the efficiency of escape; conversely, if the overlap is low, it may increase the confusion and difficulty of evacuation. Based on the route overlap parameter, the difficulty of personnel evacuation is quantified, and the personnel flow evacuation difficulty parameter is obtained, which helps building managers understand the challenges that personnel evacuation may face in emergency situations, thereby optimizing the evacuation route design and improving the safety of buildings. By analyzing personnel behavior information, the illegal use of open flames by personnel is understood, which helps to timely discover and correct unsafe behaviors, and the open flame use violation frequency parameter is obtained to quantify the frequency of illegal use of open flames by personnel. The personnel flow evacuation difficulty parameter and the open flame use violation frequency parameter are combined to obtain a parameter that comprehensively reflects the threat to building fire safety, namely the third fire safety threat parameter, which provides a comprehensive fire safety risk assessment indicator for building managers, so as to have a more comprehensive understanding of the threats to building fire safety, and thus formulate more effective preventive measures and emergency plans. At the same time, this parameter also helps to improve the fire safety awareness of people in the building and jointly maintain the safety of the building.

[0059] 3. Obtain relevant information about the surrounding environment of the target building, understand the width and flatness information of the fire lane, ensure that in an emergency, the fire truck can quickly reach the fire scene and carry out effective fire fighting and rescue work. By comprehensively considering the fire lane penetration and flatness information, the availability parameter of the fire lane can be obtained, which directly reflects the difficulty of the fire lane entering the target building area. Obtain relevant information about the fire water source, determine the capacity of the fire water pool according to the effective volume information of the fire water pool, so as to evaluate how much fire water can be provided in the event of a fire, and ensure that there is enough fire water for fire fighting operations when a fire occurs. Understand the distance between the fire water pool and the target building to evaluate the response speed of fire water in the event of a fire. The closer the distance, the faster the response speed, and the more conducive it is to timely extinguishing and controlling the fire. By comprehensively considering the effective volume of the fire water pool and the distance from the target building, the availability parameter of the fire water source can be obtained, which reflects the ability of the fire water source to provide timely and sufficient fire water in the event of a fire. By integrating the fire lane availability parameters, fire water source availability parameters, and fire equipment availability parameters, a comprehensive fire safety threat parameter is obtained. This parameter takes into account the impact of the surrounding environment of the target building and the fire equipment, especially the traffic capacity of the fire lane and the availability of the fire water source. It provides a quantitative fire safety risk assessment indicator for building managers and relevant departments, which helps to formulate more accurate fire safety strategies and emergency plans, thereby improving the building's fire response capabilities and protecting people's lives and property.

[0063] The following combination Figure 1-Figure 2 The present application is further described in detail, but the embodiments of the present invention are not limited thereto.

[0064] Reference Figure 1 , a building fire protection data collection and analysis method and system, the method comprising the following steps:

[0065] S1. Obtaining building-related information of the target building, analyzing and processing the building-related information, and obtaining a first fire safety threat parameter of the target building;

[0066] S2. Obtaining information related to electrical equipment in the target building, analyzing and processing the information related to the electrical equipment, and obtaining a second fire safety threat parameter of the target building;

[0067] S3. Obtaining personnel-related information of the target building, analyzing and processing the personnel-related information, and obtaining the third fire safety threat parameter of the target building;

[0068] S4. Obtaining information related to firefighting facilities and surrounding environment of the target building, and comprehensively analyzing the information related to firefighting facilities and surrounding environment to obtain a fourth fire safety threat parameter of the target building;

[0069] S5. Comprehensively analyzing the first fire safety threat parameter, the second fire safety threat parameter, the third fire safety threat parameter and the fire safety threat parameter to obtain the comprehensive fire safety threat parameter of the target building;

[0070] S6. Based on the comprehensive fire safety threat parameters, determine the dangerous situation and degree of harm of the fire in the target building, and issue a fire alarm prompt to the outside world based on the degree of harm.

[0071] In actual application, obtain and analyze the building-related information of the target building to understand the basic structure, materials, age, etc. of the building. The structure and materials of the building directly affect its performance in a fire, which helps to evaluate the fire resistance of the building. For example, old wooden structures and new steel structures or concrete structures perform differently in a fire. Electrical equipment is a common source of fire. Obtain relevant information about the electrical equipment of the target building to understand the status, service life, and whether there are overloads of the equipment, so as to evaluate the status of the electrical equipment and identify potential electrical fire risks, which helps to prevent electrical fires. The behavior and reaction of personnel in a fire have an important impact on the development and consequences of the fire. Understanding the behavior and mobility of personnel in the building helps to develop more effective evacuation plans and fire response strategies. Obtain and analyze the fire-fighting equipment-related information and the surrounding environment-related information of the target building to evaluate the completeness of the building's fire-fighting equipment and the safety of the surrounding environment. Complete fire-fighting facilities can quickly control the fire and reduce losses. At the same time, understanding the surrounding environment, such as whether there are flammable materials and whether the fire passages are unobstructed, is crucial for fire prevention and response. The comprehensive acquisition of various fire safety threat parameters can provide a comprehensive, multi-dimensional building fire safety assessment parameter, which is not limited to a single risk and helps to formulate more accurate preventive measures. Based on the comprehensive fire safety threat parameters, the fire hazard situation and degree of harm are judged, and an alarm is issued to warn relevant personnel and departments in time so that necessary preventive measures can be taken. Early warning before a fire occurs can greatly reduce the losses caused by fire and protect people's lives and property.

[0072] The specific step S1 includes the following sub-steps:

[0073] S11. Obtaining building-related information of the target building, the building-related information including building age information, building floor information and building structure type information;

[0074] S12. Based on the building age information, determine the remaining useful life of the target building and obtain the remaining life parameter of the target building;

[0075] S13. Based on the building floor information, determine the difficulty of escape when a fire occurs in the target building, and obtain the difficulty parameter of escape of the target building;

[0076] S14. Based on the building structure type information, determine the fire spread trend of the target building when a fire occurs, and obtain the fire spread parameters of the target building;

[0077] S15. The first fire safety threat parameter of the target building is obtained by comprehensively considering the remaining service life parameter, escape difficulty parameter and fire spread parameter.

[0078] In actual application, the building age information of the target building is obtained, the remaining service life of the target building is evaluated, and possible problems in the future are predicted. Old buildings may have more safety hazards, such as circuit aging, material decay, etc., so special attention is needed. The height and complexity of the floor directly affect the speed and efficiency of escape. It is more difficult to escape from a high-rise building during a fire. Based on the building floor information, the difficulty of escape for people in the building during a fire is predicted. If the floor is set to the 6th floor or below, it is judged that the escape difficulty of the target building is relatively easy when a fire occurs, and the escape difficulty parameter of the target building is 1; if the floor is above the 6th floor and below the 15th floor, it is judged that the escape difficulty of the target building is medium when a fire occurs, and the escape difficulty parameter of the target building is 2; if the floor is 15th floor or above, it is judged that the escape difficulty of the target building is difficult when a fire occurs, and the escape difficulty of the target building is 3; different building structures have different effects on the spread of fire, for example The fire spreads faster in wooden and open structures, while it spreads relatively slowly in reinforced concrete and closed structures. The fire spread speed in the building is predicted based on the building structure type information. The fire spread parameter is set to 3 for wooden and open structures with fast fire spread speed, 2 for reinforced concrete and open structures with moderate fire spread speed, or wooden and closed structures, and 1 for reinforced concrete and closed structures with slow fire spread speed. The fire spread parameter is helpful to predict the severity of the fire and formulate corresponding fire extinguishing strategies. Comprehensive consideration of the remaining life parameters, escape difficulty parameters and fire spread parameters can comprehensively evaluate the fire safety status of the building, so as to formulate targeted preventive measures and response strategies to ensure the safety of people's lives and property.

[0079] The specific step S2 includes the following sub-steps:

[0080] S21. Obtaining information related to electrical equipment in the target building, the information related to electrical equipment including equipment power load information, equipment installation and maintenance information, and equipment use specification information;

[0081] S22. Based on the power load information of the equipment, determine whether there is an unbalanced load distribution of the power equipment in the target building, and obtain the abnormal load parameters of the power equipment;

[0082] S23. Based on the equipment installation and maintenance information, determine whether the electrical equipment in the target building has unqualified maintenance quality, and obtain maintenance abnormality parameters of the electrical equipment;

[0083] S24. Based on the equipment usage specification information, determine whether there is an operation error in the electrical equipment in the target building, and obtain abnormal usage parameters of the electrical equipment;

[0084] S25. Based on the load abnormality parameter, maintenance abnormality parameter and usage abnormality parameter, determine the probability of the abnormality of the electrical equipment causing a fire threat to the target building, and obtain a second fire safety threat parameter of the target building.

[0085] In actual use, electrical equipment is one of the important sources of fire hazards in buildings. A comprehensive understanding of the power consumption, installation and maintenance status, and use norms of the equipment will help to timely discover potential safety hazards and prevent the occurrence of electrical fires. Load abnormality is one of the common causes of electrical fires. By analyzing the power consumption data of electrical equipment, it is determined whether there are areas in the target building where the power load is obviously too high. The power load of the electrical equipment in this area is compared with the set standard power load to determine whether there is an unbalanced load distribution of the electrical equipment, identify equipment failures or fire risks that may be caused by excessive or insufficient loads, and obtain the load abnormality parameters of the electrical equipment. The quality of equipment maintenance directly affects the safe operation of the equipment. Qualified maintenance can ensure that the equipment will not generate excessive heat or cause short circuits during normal operation, thereby reducing the risk of fire. By evaluating the quality of equipment maintenance, it is determined whether there are equipment failures or potential fire hazards caused by improper maintenance. By checking whether the equipment is operated and used in a standardized manner, potential fire hazards caused by misoperation or illegal use of equipment can be discovered. Correct equipment use specifications are an important prerequisite for ensuring the safe operation of equipment. Avoiding illegal operations can effectively prevent equipment failures and fire accidents and ensure safety in buildings. By combining abnormal load parameters, abnormal maintenance parameters and abnormal usage parameters, the probability of fire threats to buildings caused by abnormal electrical equipment is comprehensively assessed to obtain the second fire safety threat parameter. This parameter comprehensively reflects the fire safety threat of building electrical equipment, which helps building managers to fully understand the safety status of electrical equipment and provides an important basis for formulating targeted preventive measures and emergency plans. At the same time, it also helps to improve the fire safety awareness of people in the building and jointly maintain the safety of the building.

[0086] The specific step S3 includes the following sub-steps:

[0087] S31. Obtaining personnel-related information of the target building, the personnel-related information including personnel flow pattern information and personnel behavior information;

[0088] S32. The personnel flow pattern information refers to the normal flow route information of personnel. Based on the personnel flow pattern information, the overlap between the normal flow route of personnel and the emergency evacuation route is determined to obtain the route overlap parameter;

[0089] S33. Based on the route overlap parameter, obtain the personnel flow evacuation difficulty parameter of the target building;

[0090] S34. Based on the personnel behavior information, determine the illegal use of open flames by personnel and obtain the frequency parameter of illegal use of open flames;

[0091] S35. The third fire safety threat parameter of the target building is obtained by combining the personnel flow evacuation difficulty parameter and the open flame use violation frequency parameter.

[0092] In actual application, by analyzing the degree of overlap between normal personnel flow routes and emergency evacuation routes, the efficiency and safety of personnel evacuation in emergency situations are evaluated. A high degree of route overlap means that in an emergency, personnel can identify and transfer to the evacuation route more quickly, reducing the difficulty of evacuation and improving escape efficiency; conversely, if the overlap is low, it may increase the confusion and difficulty of evacuation. Based on the route overlap parameter, the difficulty of personnel evacuation is quantified, and the personnel flow evacuation difficulty parameter is obtained, which helps building managers understand the challenges that personnel evacuation may face in emergency situations, thereby optimizing the evacuation route design and improving the safety of buildings. Open flames are one of the important factors that cause fires. By analyzing personnel behavior information and understanding the illegal use of open flames by personnel, it is helpful to promptly discover and correct unsafe behaviors, obtain the open flame use violation frequency parameter, and quantify the frequency of illegal use of open flames by personnel. By combining the personnel flow evacuation difficulty parameter and the open flame use violation frequency parameter, we get a parameter that comprehensively reflects the building fire safety threat, namely the third fire safety threat parameter, which provides a comprehensive fire safety risk assessment indicator for building managers, so as to have a more comprehensive understanding of the threats to the building's fire safety, and thus formulate more effective preventive measures and emergency plans. At the same time, this parameter also helps to improve the fire safety awareness of people in the building and jointly maintain the safety of the building.

[0093] The specific step S4 includes the following sub-steps:

[0094] S41. Obtaining fire-fighting facility-related information of the target building, the fire-fighting facility-related information includes fire-fighting equipment type information, fire-fighting equipment quantity information and fire alarm equipment usage information;

[0095] S42. Based on the fire-fighting equipment type information and the fire-fighting equipment quantity information, the availability of the fire-fighting equipment when a fire occurs in the target building is determined to obtain the availability parameters of the fire-fighting equipment;

[0096] S43. The fire alarm equipment usage information includes the number of valid alarms and false alarms of the fire alarm equipment. Based on the valid alarm number information and false alarm number information, the false alarm rate of the fire alarm equipment when a fire occurs in the target building is determined to obtain the false alarm rate parameter of the fire alarm equipment;

[0097] S44. Based on the availability parameter and the false alarm rate parameter, obtain the fire equipment availability parameter of the target building;

[0098] S45. Obtain information related to the surrounding environment of the target building, and based on the fire-fighting equipment availability parameter, perform a comprehensive analysis on the information related to the surrounding environment and the fire-fighting equipment availability parameter to obtain a fourth fire safety threat parameter of the target building.

[0099] In actual application, the relevant information of fire-fighting facilities is obtained. Based on the information of the types and quantity of fire-fighting equipment, the more types and quantities of fire-fighting equipment there are, the more equipment is available for fire-fighting operations when a fire occurs, and the greater the availability of fire-fighting equipment. The actual availability of fire-fighting equipment when a fire occurs is evaluated, and the availability parameters of fire-fighting equipment are obtained. The availability of fire-fighting equipment is directly related to the efficiency and effectiveness of fire response, and is an important factor in ensuring building safety. By analyzing the number of effective alarms and the number of false alarms, the false alarm rate of the alarm equipment is calculated. The high or low false alarm rate affects the credibility of the alarm equipment. A high false alarm rate may cause people to ignore the real fire alarm, thereby bringing potential safety risks. Considering the availability of fire-fighting equipment and the false alarm rate of alarm equipment, a comprehensive fire-fighting equipment availability parameter is obtained. This parameter provides a visual indicator for building managers to evaluate and improve the effectiveness of fire-fighting facilities. Combined with the surrounding environment of the building and the availability of fire-fighting equipment, a comprehensive analysis is conducted to obtain a quantitative fire safety threat parameter. This parameter provides a comprehensive and quantitative fire safety risk assessment indicator for building managers and relevant departments. It is the basis for evaluating building fire safety and ensures that there are sufficient fire-fighting facilities and alarm systems to respond when a fire occurs.

[0100] The specific step S45 includes the following sub-steps:

[0101] S451. Obtaining information related to the surrounding environment of the target building, the surrounding environment related information including fire lane information entering the target building area and fire water source information of the target building;

[0102] S452. The fire lane information includes fire lane width information and fire lane flatness information. Based on the fire lane width information and fire lane flatness information, the traffic capacity of the fire truck entering the target building area is determined to obtain the fire lane availability parameter;

[0103] S453. The fire water source information includes the effective volume information of the fire water pool and the distance information between the fire water pool and the target building;

[0104] S454. Based on the effective volume information of the fire water tank, obtain the fire water consumption parameters of the fire water source;

[0105] S455. Based on the distance information between the fire water tank and the target building, obtain the fire water response distance parameter of the fire water source;

[0106] S456. Combining the fire water consumption parameter and the fire water response distance parameter, obtain the fire water source availability parameter;

[0107] S457. Based on the fire equipment availability parameter, the fire equipment availability parameter and the fire water source availability parameter are combined to obtain the fourth fire safety threat parameter of the target building.

[0108] In actual application, obtain relevant information about the surrounding environment of the target building, understand the width information and flatness information of the fire lane. The flatness of the fire lane directly affects the driving speed and safety of the fire truck, which is crucial for fire rescue, ensuring that in an emergency, the fire truck can quickly reach the fire scene and carry out effective fire fighting and rescue work. Set the fire lane width standard, compare the fire lane width information with the width standard and score it. For example, if the width fully meets the standard, it will get a full score of 1, and if it is slightly insufficient, it will be deducted accordingly, and the lane width score is [0,1]; for flatness, score according to the severity and impact range of the convexity and concavity, and the lane flatness score is [0,1]; considering the fire lane width and flatness score comprehensively, the fire lane availability parameter can be obtained, which directly reflects the difficulty of the fire lane entering the target building area. Obtain relevant information about the fire water source, determine the capacity of the fire water pool according to the effective volume information of the fire water pool, so as to evaluate how much fire water can be provided in the event of a fire, and ensure that there is enough fire water for fire fighting operations when a fire occurs. Understand the distance between the fire water pool and the target building to evaluate the response speed of fire water in the event of a fire. The closer the distance, the faster the response speed, which is more conducive to timely fire extinguishing and fire control. For example, when the distance between the fire water pool and the target building is 30 meters, the response distance parameter of fire water in the event of a fire is 3; when the distance between the fire water pool and the target building is 60 meters, the response distance parameter of fire water is 2; when the distance between the fire water pool and the target building is 90 meters, the response distance parameter of fire water is 1. By comprehensively considering the effective volume of the fire water pool and the distance from the target building, the availability parameter of the fire water source can be obtained, which reflects the ability of the fire water source to provide timely and sufficient fire water in the event of a fire. By integrating the fire lane availability parameters, fire water source availability parameters, and fire equipment availability parameters, a comprehensive fire safety threat parameter is obtained. This parameter takes into account the impact of the surrounding environment of the target building and the fire equipment, especially the traffic capacity of the fire lane and the availability of the fire water source. It provides a quantitative fire safety risk assessment indicator for building managers and relevant departments, which helps to formulate more accurate fire safety strategies and emergency plans, thereby improving the building's fire response capabilities and protecting people's lives and property.

[0109] The specific step S5 includes the following sub-steps:

[0110] S51. Mark the first fire safety threat parameter as XF1, the second fire safety threat parameter as XF2, the third fire safety threat parameter as XF3, and the fourth fire safety threat parameter as XF4;

[0111] S52. The comprehensive fire safety threat parameter ZXF of the target building is calculated by the formula ZXF=u1×XF1+u2×XF2+u3×XF3+u4×XF4, where u1, u2, u3 and u4 are proportional factors and are all greater than zero.

[0112] The specific step S6 includes the following sub-steps:

[0113] S61. Based on the comprehensive fire safety threat parameter ZXF, the comprehensive fire safety threat parameter is compared with a preset standard fire safety threat parameter BXF;

[0114] S62. When ZXF<BXF, there is no fire hazard in the target building;

[0115] S63. When ZXF ≥ BXF, the target building is in danger of fire, and the difference between the comprehensive fire safety threat parameter and the standard fire safety threat parameter is calculated to obtain the fire safety threat difference;

[0116] S64. Based on the fire safety threat difference, determine the hazard level of a fire in the target building, and issue a fire alarm prompt to the outside world based on the hazard level.

[0117] In actual application, by comparing the comprehensive fire safety threat parameter ZXF obtained through actual evaluation with the preset standard fire safety threat parameter BXF, it can be judged whether the fire safety status of the target building meets the safety standard, making the fire safety assessment more objective and measurable, helping to timely discover potential fire hazards and provide a basis for subsequent fire prevention and response measures. When ZXF<BXF, it indicates that the fire safety status of the target building is better than the preset safety standard, so it can be considered that there is no danger of fire at present, that is, under the current situation, the fire safety of the building is guaranteed, and there is no need to take emergency fire prevention measures. When ZXF≥BXF, it indicates that the fire safety status of the target building has reached or exceeded the maximum threat value allowed by the preset safety standard, so there is a danger of fire, prompting building managers and fire departments to pay immediate attention and take corresponding preventive measures to reduce the possibility and potential hazards of fire. By calculating the difference between the comprehensive fire safety threat parameters and the standard fire safety threat parameters, that is, the fire safety threat difference, the degree of hazard of fire in the target building can be further quantified. The larger the difference, the more serious the potential fire hazard. It provides the fire department with a specific numerical basis for the degree of fire hazard, which helps them to more accurately assess fire risks and formulate more effective prevention and response measures, thereby reducing potential fire losses.

[0118] The specific step S64 includes the following sub-steps:

[0119] S641. Based on the fire safety threat difference, the hazard level of the fire in the target building is divided into a first-level hazard fire, a second-level hazard fire, and a third-level hazard fire;

[0120] S642. For a first-level fire hazard, send a first-level fire alarm signal to the outside world, use firefighting equipment or firefighting water sources to extinguish the fire and prevent the fire from spreading further;

[0121] S643. For a Class II fire, send a Class II fire alarm message to the outside world, organize the evacuation of personnel in an orderly manner, and request fire fighting and rescue;

[0122] S644. For a level 3 fire, send a level 3 fire alarm message to the outside world to request fire rescue. After the fire is extinguished, clean up the fire residue to avoid secondary pollution.

[0123] In actual application, the fire safety threat difference is used to classify fire hazards into different levels, which helps to more accurately assess the severity of the fire and provide clear guidance for the corresponding measures, making the emergency response more rapid and effective. For the first-level hazard fire, timely use firefighting equipment or fire water sources to extinguish the fire to prevent the spread of the fire, effectively control the fire, and reduce casualties and property losses. For the second-level hazard fire, organize personnel to evacuate in an orderly manner and request firefighting and rescue to deal with more complex fire situations. While ensuring the safe evacuation of personnel, seek external support, increase the chance of successful firefighting and reduce potential risks. For the third-level hazard fire, while requesting firefighting and rescue, consider the post-fire cleanup work to avoid secondary pollution. This level of fire is often more serious, so comprehensive rescue operations are required. In addition, considering the environmental impact after the fire, timely cleaning of residues will help to quickly restore normal social order, thereby improving the efficiency and effectiveness of fire response, protecting people's lives and property safety to the greatest extent, and reducing the negative impact of fire on the environment and social order.
