Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire monitoring, in particular to a fire intelligent monitoring method and system based on regional feature data recognition. BACKGROUND

[0002] With global climate change and frequent natural disasters, fire has become a serious problem that endangers the ecological environment and human safety. The rapid spread of fire caused by not being handled in time not only leads to the destruction of the ecological system, but also has a profound impact on air quality, climate change, etc., and is more likely to cause loss of personnel and property. Therefore, it is of great significance to establish an efficient and accurate fire monitoring and early warning system, especially for campus fire monitoring. Campus fires often occur in student dormitories, laboratories, libraries and other places where personnel frequently come and go. Students have weak fire awareness and do not understand basic escape knowledge, so fire monitoring is a crucial step to ensure the safety of teachers and students, maintain educational order, and greatly improve emergency response capabilities.

[0003] At present, there are still problems that the fire risk situation of the monitoring area cannot be accurately analyzed, and the appropriate division standard cannot be selected according to the distribution of regional combustible materials to divide the region. Although the detection technology for fire in the prior art has been relatively perfect and can accurately discover fire, the timeliness and accuracy of fire monitoring are closely related to the area of the monitoring area. If the region is directly divided by a fixed standard, the area standard of the region will be too large, which will cause the monitoring area to be unable to discover fire in time during monitoring, and if the area standard of the region is too small, it will lead to the problem of increasing resource occupation and large data processing amount of fire monitoring, affecting the efficiency of fire monitoring. SUMMARY

Although the detection technology for fire in the prior art has been relatively perfect and can accurately discover fire, the timeliness and accuracy of fire monitoring are closely related to the area of the monitoring area.

[0080] The following description is provided to disclose the present application so that those skilled in the art can implement the present application. The preferred embodiments in the following description are only examples, and other obvious modifications can be made by those skilled in the art.

[0081] REFERENCE Figure 1 - Figure 4 As shown in the figure, the fire intelligent monitoring method based on regional feature data recognition in the embodiment of the present application comprises:

[0082] S101: acquiring monitoring area information, wherein the monitoring area information comprises monitoring area area information and monitoring area function unit information;

[0083] S102: dividing the monitoring area according to the monitoring area information to acquire basic monitoring area information;

[0084] Specifically, the monitoring area is divided according to the monitoring area information to acquire the basic monitoring area information, which specifically comprises:

[0085] According to the monitoring area information, regional combustible information is acquired, wherein the regional combustible information comprises combustible type information and combustible position information;

[0086] According to the regional combustible information, a reference area area is acquired;

[0087] According to the monitoring area information, the minimum area of the monitoring area function unit is taken as a first threshold of the area area;

[0088] Based on the fire monitoring requirement, the maximum monitorable area of the fire is taken as a second threshold of the area area;

[0089] According to the reference area area, the first threshold of the area area and the second threshold of the area area, it is judged whether the reference area area can be used as a regional division standard to acquire regional division reference information.

[0090] According to the area division reference information, the to-be-monitored area is divided to obtain basic monitoring area information;

[0091] If the reference area size is greater than the first area size threshold and less than the second area size threshold, the reference area size is taken as the area division reference to divide the to-be-monitored area;

[0092] If the reference area size is less than the first area size threshold, the first area size threshold is taken as the area division reference to divide the to-be-monitored area;

[0093] If the reference area size is greater than the second area size threshold, the second area size threshold is taken as the area division reference to divide the to-be-monitored area.

[0094] In this scheme, the basic monitoring area is divided by combining the area combustible information, the functional unit characteristics and the monitoring capability boundary. The reference area size is determined based on the area combustible information, so that the area division is closely combined with the core element (combustible material) of the fire risk, avoiding the problem that the traditional equalization division is disconnected with the actual fire hazard distribution, and making the monitoring focus of each basic monitoring area more clear. The first area size threshold (the minimum size of the functional unit) ensures the integrity of the area function, and ensures that the monitoring data can accurately reflect the fire risk characteristics. For example, when monitoring the fire in the classroom in the campus, the classroom is taken as a functional unit, and the classroom area is directly taken as the fire monitoring area for monitoring. If the area is further reduced, the monitoring accuracy is not improved, and some areas are easily ignored, affecting the timeliness and accuracy of fire monitoring. The second area size threshold (the maximum monitorable area of fire) limits the upper limit of the area from the monitoring technology capability, ensures that each basic monitoring area after division is within the effective coverage and accurate identification range of the monitoring system, and avoids the monitoring blind area or data distortion caused by the too large area, laying a foundation for the accurate collection of subsequent fire characteristic data.

[0095] Specifically, according to the area combustible information, the reference area size is obtained, specifically including:

[0096] S301: According to the combustible type information, the heat release rate, the heat radiation efficiency and the ignition heat flux threshold corresponding to each combustible are obtained, and the ignition heat flux threshold represents the radiation heat flow required for the unit area combustible surface to ignite;

[0097] S302: According to the area combustible information, taking any area combustible as the first area combustible and the second area combustible, the area combustible combination information is obtained;

[0098] S303: According to the regional fuel combination information, the heat release rate corresponding to the first regional fuel, the heat radiation efficiency, and the ignition heat flux threshold corresponding to the second regional fuel are obtained as the basis to obtain the fuel distance deviation coefficient;

[0099] S304: Repeat steps S302-S303 until all regional fuel combination corresponding fuel distance deviation coefficients are obtained;

[0100] S305: According to the fuel distance deviation coefficient, the first vector and the second vector corresponding to each regional fuel combination are obtained;

[0101] S306: The product of the first vector and the second vector corresponding to each regional fuel combination is taken as the fuel combination characteristic coefficient of the regional fuel combination;

[0102] S307: The regional fuel combination corresponding to the minimum value of the fuel combination characteristic coefficient is taken as the reference regional fuel combination;

[0103] S308: According to the reference regional fuel combination, the maximum influence distance of the reference regional fuel combination is obtained;

[0104] S309: The square of the product of the maximum influence distance of the fuel combination and the fuel combination characteristic coefficient corresponding to the reference regional fuel combination is taken as the reference area.

[0105] In this scheme, the reference area is accurately derived through the characteristics and interaction of the fuel, which lays a solid foundation for the regional division of intelligent fire monitoring. In the traditional method, only the geographical boundary or functional division is simply based on, and the heat transfer and ignition correlation between the fuels are ignored. In this scheme, the heat release rate, heat radiation efficiency, and ignition heat flux threshold are integrated to construct the "ignition risk model" of the fuel combination, and the combination risk is quantified by vector multiplication. The reference combination with the highest risk coupling degree is selected, and the "fuel combination most likely to cause chain fire" is locked through the reference area, providing a basis for monitoring regional division.

[0106] Specifically, according to the fuel distance deviation coefficient, the first vector and the second vector corresponding to each regional fuel combination are obtained, which specifically includes:

[0107] According to the fuel distance deviation coefficient corresponding to each regional fuel combination, the first regional fuel is taken as the origin, the first regional fuel is directed to the second regional fuel as the vector direction, and the fuel distance deviation coefficient is taken as the vector module length to obtain the first vector;

[0108] Obtain the environment information of the region to be monitored;

[0109] According to the environment information of the region to be monitored and the combustible position information, wind speed information corresponding to the first region combustible in each region combustible combination is obtained, and the wind speed information includes wind speed speed information and wind speed direction information;

[0110] According to the wind speed information corresponding to the first region combustible, a second vector corresponding to each region combustible combination is obtained.

[0111] The first vector and the second vector are specifically as follows:

[0112]

[0113] In the formula, The first vector is a module length, is the position of the first region combustible in the i th region combustible combination, is the position of the second region combustible in the i th region combustible combination, The distance between the first region combustible and the second region combustible in the i th region combustible combination is represented by, is the heat release rate of the first region combustible in the i th region combustible combination, is the ignition heat flux threshold of the second region combustible in the i th region combustible combination, The second vector is a module length, is the wind speed corresponding to the first region combustible in the i th region combustible combination.

[0114] In this scheme, by accurately depicting the combustible association, dynamically integrating environmental impact, and quantifying vector modeling, intelligent fire monitoring is provided with deep support from "static feature recognition" to "dynamic risk deduction". Through the "first vector" (with the combustible distance bias coefficient as the module length and the direction as the direction), the spatial position, heat release rate, and other static characteristics of different regional combustibles are converted into an intuitive vector model. For example, the vector module length of the laboratory (high heat release) and the library (flammable material) is longer and the direction is more explicit, directly reflecting the "high risk association", solving the problem of "combustible distribution relying on coordinates only, unable to reflect risk transmission" in traditional methods. The formula integrates heat release rate, ignition threshold, and other parameters, allowing the fire risk of "two regional combustible combinations" (such as the possibility of "laboratory leakage → warehouse fire") to be upgraded from qualitative description to quantitative calculation. Compared with traditional "only marking combustible position", it can more accurately identify high-risk combinations of "potential chain fires", and through the "second vector" (based on wind speed information), real-time environmental dynamic factors (such as the impact of wind on flame spread and heat transfer) are integrated into the risk model. For example, under strong wind conditions, the "second vector module length" of the first regional combustible increases, reflecting the increased fire transmission risk of the second region, solving the pain point of "static combustible analysis unable to adapt to dynamic environment". Combined with "environmental information of the area to be monitored + combustible position", multi-dimensional data such as wind speed and direction are obtained simultaneously, allowing the vector model to cover complex scenarios such as "wind-assisted fire spread" (such as higher risk of combustible combination in the wind direction), improving the accuracy of early fire warning.

[0115] S103: Obtain regional combustible information in each basic monitoring area according to the basic monitoring area information;

[0116] S104: Adjust the basic monitoring area based on the regional combustible information in each basic monitoring area to obtain fire monitoring area information;

[0117] Specifically, the basic monitoring area is adjusted based on the regional combustible information in each basic monitoring area to obtain the fire monitoring area, which specifically includes:

[0118] According to the regional combustible information in each basic monitoring area, the corresponding regional fire monitoring center of each basic monitoring area is obtained;

[0119] Based on the analysis of fire monitoring needs, the regional combustible standard density is obtained;

[0120] According to the basic monitoring area information, the personnel density information, the maximum personnel evacuation density information, and the regional combustible density information corresponding to each basic monitoring area are obtained;

[0121] According to the region combustible density information corresponding to the basic monitoring area and the region combustible standard density, obtain fire risk region information, the fire risk region represents the basic monitoring area whose combustible density exceeds the region combustible standard density;

[0122] According to the personnel density information, the personnel evacuation maximum density information, the combustible density information and the region combustible standard density, obtain a region adjustment coefficient;

[0123] Taking the fire risk region as the basis, the product of the region adjustment coefficient and the area of the fire risk region is taken as the adjusted region area, and the region fire monitoring center corresponding to the fire risk region is taken as the region adjustment center point to adjust the fire risk region;

[0124] The adjusted fire risk region and the basic monitoring region are taken as the fire monitoring region;

[0125] The region adjustment coefficient is specifically:

[0126]

[0127] In the formula, is the region adjustment coefficient, is the region combustible density, is the region combustible standard density, is the personnel density, is the personnel evacuation maximum density, is the fire personnel influence coefficient, and is the weight coefficient.

[0128] In the scheme, by fusing multi-dimensional data such as combustible density and personnel distribution, the fire monitoring region is dynamically adjusted, and the expansion / shrinking monitoring range is realized by "region adjustment coefficient x risk region area", which not only covers the core risk area of "combustible overload", but also corrects the parameters such as personnel density and evacuation capacity (such as expanding the monitoring of personnel-intensive areas to cover escape routes), solving the problem that the traditional "static division" does not match the dynamic changes of actual fire risk. The monitoring region divided by the traditional method is fixed and cannot adapt to the fluctuations of combustible density and the dynamic distribution of personnel. The adjustment coefficient fuses "combustible density ratio" and "personnel influence coefficient" to reflect the synergistic effect of fire spread potential (combustible overload) and evacuation difficulty (personnel-intensive), and through the comparison of "region combustible density and standard density", the high-risk basic region is directly identified, the fire monitoring efficiency is improved, and a data basis is provided for subsequent fire monitoring setting. By taking the "region fire monitoring center" as the adjustment reference point, the stability of the region in the adjustment process is ensured, and the influence of the chain reaction of region adjustment on adjacent regions is avoided, so that the fire can be found in time and accurately.

[0129] It should be noted that in the embodiment, represents the weight of the influence of the combustible density on the fire risk, represents the weight of the influence of the personnel density on the fire risk, and the adjusted fire risk area and the unadjusted basic monitoring area are taken as the fire monitoring area.

[0130] Specifically, according to the regional combustible information in each basic monitoring area, the regional fire monitoring center corresponding to each basic monitoring area is obtained, specifically including:

[0131] According to the regional combustible information in each basic monitoring area, the regional combustible combination information corresponding to each basic monitoring area is obtained;

[0132] Taking the regional combustible in any basic monitoring area as the initial risk combustible of the basic monitoring area;

[0133] According to the regional combustible combination information corresponding to each basic monitoring area, the regional combustible combination in which the initial risk combustible is the first regional combustible in the regional combustible combination is taken as the initial risk combustible combination;

[0134] The combustible distance bias coefficient corresponding to each initial risk combustible combination is obtained;

[0135] Taking the initial risk combustible corresponding to the maximum value of the sum of the combustible distance bias coefficients of the initial risk combustible combination as the regional fire characteristic combustible;

[0136] According to the combustible position information, the position corresponding to the regional fire characteristic combustible is taken as the regional fire monitoring center.

[0137] In the scheme, through the screening of “initial risk combustible→initial risk combination→regional fire characteristic combustible”, the “core combustible with the greatest influence on the regional fire risk” (such as a high-heat-release and high-flammable chemical storage point) is accurately locked from the scattered combustible information of the basic monitoring area, the problem that the traditional method “monitors all combustibles without distinction and cannot focus on the core risk” is solved, the risk correlation of different combustible combinations is quantified by using “combustible distance bias coefficient” (the greater the coefficient, the higher the combination fire risk), and “which combustible combination is the most dangerous” is changed from qualitative judgment to quantitative sorting (taking the maximum value of the sum of the coefficients), which directly points to the “fire risk engine” in the region;

[0138] It can be understood that the location of the regional fire monitoring center (characteristic combustible location) is not simply the geometric center, but the physical anchor point with the most concentrated fire risk. Compared with the traditional "take the regional center" method, this center is more relevant and representative of fire risk, improving the timeliness and accuracy of fire monitoring. When the distribution and combined risk of combustibles in the region change (such as the addition of high-risk chemical storage), the monitoring center can dynamically migrate by recalculating the "initial risk combination → characteristic combustible" to always anchor the latest core risk source.

[0139] S105: According to the fire monitoring area information, the fire monitoring is performed on each fire monitoring area.
