[0002] In traditional firefighting management, manual dispatch is the main method. When a fire alarm is received, the responding personnel usually notify the firefighters immediately through the telephone or radio system, informing them of the specific location and basic conditions of the fire, including the fire, smoke, and trapped personnel. After receiving the notification, the firefighters respond quickly and go to the scene to extinguish the fire and rescue. In this process, the rapid response and coordinated combat capabilities of the firefighters are crucial. However, due to the reliance on manual dispatch, the timeliness of information transmission and judgment is limited.
[0003] Existing technologies usually formulate rescue plans based on factors such as the severity of the fire, the density of people at the fire site, the geographical location and the surrounding environment. Although this solution can improve response efficiency to a certain extent, manual dispatch still relies on experience and subjective judgment, and there is a limitation that it is difficult to allocate resources optimally according to actual conditions. In complex fire scenes, dispatchers may face the risk of information asymmetry and misjudgment, resulting in irrational resource allocation, thus affecting the rescue effect. Therefore, how to improve the scientificity and accuracy of dispatch has become a key issue that needs to be urgently addressed in modern fire management. Summary of the invention

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0017] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0018] Figure 1 It is a flowchart schematically showing the steps of a fire management method based on the combination of Internet and traditional management according to an embodiment of the present invention.
[0019] like Figure 1 As shown, a fire management method based on the combination of Internet and traditional management includes steps S1 to S5.
[0020] Step S1: Obtain fire situation data.
[0021] The fire situation data include the longitude and latitude coordinates of the fire location, the floor number of the fire location, the population density of the city where the fire location is located, and the flammability of flammable materials at the fire location.
[0022] In one embodiment, the distance between the fire location and the fire station is calculated. x Including: Get the latitude and longitude coordinates of the fire location ( i 1, f 1) and recorded as the first coordinate, where f 1 is the longitude of the fire location, i 1 is the latitude of the fire location; get the longitude and latitude coordinates of the fire station ( i 2, f 2) and recorded as the second coordinate, where f 2 is the longitude of the fire station, i 2 is the latitude of the fire station; the distance between the fire location and the fire station is calculated based on the first coordinate and the second coordinate x : x = R ×arccos(sin i 1×sin i 2+cos i 1×cos i 2×cos( f 2- f 1)); where R is the radius of the Earth.
[0023] Step S2: Calculate the fire location score α .
[0024] Among them, the fire location score α It is positively correlated with the population density of the city where the fire location is located. α It is positively correlated with the distance between the fire location and the fire station.
[0025] In one embodiment, the fire location score is calculated α The formula is: , x is the distance between the fire location and the fire station, k is the population density of the city where the fire is located, norm () is the normalization function.
[0026] It should be noted that the distance between the fire site and the fire station x The larger the radius, the longer it takes for rescuers to reach the fire site. At this time, the fire may be in a more uncontrollable state, so more rescuers need to be dispatched. x The larger the fire location score α The larger the value, the greater the subsequent comprehensive score. T The larger the fire is, the more rescue workers will be dispatched. The population density of the city where the fire is located k The larger the area, the more people who need to be rescued (such as those trapped at the fire scene) or evacuated in the fire location than in remote areas with sparse populations, so more rescue workers are needed to carry out rescue work at the fire location. k The larger the fire location score α The larger it is, the greater the subsequent comprehensive score will be, and the more rescuers will be dispatched subsequently.
[0027] Step S3: Calculate floor score β , , f is the floor number where the fire is located, f 0 is the preset floor threshold. F is the total number of floors of the building where the fire is located, norm () is the normalization function.
[0028] It should be noted that due to the presence of rescue equipment such as ladder trucks and high-rise water supply trucks, rescue on lower floors is less difficult. However, when the number of floors where the fire is located is higher than a threshold, it is difficult for ladder trucks and other equipment to carry out effective rescue. At this time, the rescue difficulty is greater, so more rescue personnel need to be dispatched to control the fire and prevent the fire from causing greater harm. In one embodiment, the floor number threshold f 0 is 11.
[0029] Step S4: Obtaining the combustion material score c , where the combustion score is positively correlated with the flammability of the burning material.
[0030] In one embodiment, the combustion material score is obtained c Includes: In response to the presence of gaseous combustibles at the fire location, the burning material score is c = y 1, in response to the presence of liquid combustibles and the absence of gaseous combustibles at the fire location, the burning material score is c = y 2. In response to the absence of gaseous and liquid combustibles at the fire location, the burning material score c = y 3. y 1. y 2 and y 3 are all preset combustion coefficients and y 3< y 2< y 1.
[0031] It should be noted that liquid flammables have a low flash point, such as gasoline and alcohol, and if liquid flammables flow to low-lying areas, they may cause the fire to spread further. Gas flammables have a very high risk of explosion when mixed with air, so gas flammables have the highest degree of hazard, followed by liquid flammables, and solid flammables have a lower degree of hazard. Based on this, when there are gas flammables at the fire site, the burning material score is c maximum( c = y 1); When there is no gaseous flammable material but there is liquid flammable material at the fire site, the score of the burning material is c Medium size ( c = y 2); When there are no gaseous or liquid combustibles at the fire site, the score of the burning material is c Minimum ( c = y 3).
[0032] Step S5: Score the fire location α , Floor score β And the burning material score c Weighted sum to get the overall score T ,in T = or 1 α + or 2 β + or 3 c , or 1. or 2 and or3 are all weight coefficients of preset size.
[0033] In one embodiment, or 1. or 2 and or 3 are .
[0034] In another embodiment, historical data related to fires are obtained, including the fire location score, floor score, and burning material score of each fire event, as well as the corresponding fire loss or number of victims. Multiple linear regression analysis is used, with the fire loss or number of victims as the dependent variable, and the fire location score, floor score, and burning material score as the independent variables, so as to evaluate the influence of each score on the fire loss. The weight of each factor (fire location score, floor score, and burning material score) is obtained through the coefficient of the regression model.
[0035] Step S6: Based on the comprehensive score T Determine the number of rescuers.
[0036] Among them, the comprehensive score T Positively correlated with the number of rescuers.
[0037] In one embodiment, based on the comprehensive score T The formula for determining the number of rescuers is: , M The number of rescuers, A 1. A 2 and A 3 are all first score thresholds of preset size and A 1< A 2< A 3. m 1. m 2 and m 3 are all preset values, and m1 <m2<m3。
[0038] In another embodiment, according to the comprehensive score T The formula for determining the number of rescuers is: ,in M The number of rescuers, N The number of all rescuers from the fire station that dispatched the rescuers, T 0 is a second score threshold of a preset size.
[0039] Furthermore, in response to receiving a signal indicating the presence of inflammable and explosive substances at the fire site, the number of rescuers is corrected: M’ = M × Q ,M is the number of rescuers before correction, M’ is the corrected number of rescuers, Q is the correction factor for the preset size, and Q >1; responds to the corrected number of rescuers M’ When the number is greater than the number of all rescuers in the fire station, a distress signal is sent to other fire stations so that they can dispatch rescuers.
[0040] Figure 2 It is a structural block diagram schematically showing a fire management system based on the combination of Internet and traditional management according to this embodiment.
[0041] The present invention also provides a fire management system based on the combination of Internet and traditional management. Figure 2 As shown, the system includes a processor and a memory, wherein the memory stores computer program instructions. When the computer program instructions are executed by the processor, a fire management system based on the combination of the Internet and traditional management according to the first aspect of the present invention is implemented.
