[0084] Step S102, identifying the plurality of internal monitoring data, determining whether there is a fire hazard, and selecting a fire hazard building and hazard monitoring data if there is a fire hazard.

[0085] In an embodiment of the present invention, internal monitoring feature data is obtained by performing feature identification and recording on internal monitoring data, and then feature matching is performed on the internal monitoring feature data based on preset fire hazard feature data to determine whether there is a fire hazard. Specifically: when the feature matching is successful, it is determined that there is a fire hazard. At this time, the corresponding internal monitoring data is marked as dangerous monitoring data, and the fire interconnected building corresponding to the dangerous monitoring data is marked as a fire hazard building, thereby realizing the selection of fire hazard buildings and dangerous monitoring data; when the feature matching is unsuccessful, it is determined that there is no fire hazard.

[0086] It is understandable that the preset fire hazard characteristic data includes fire flame color characteristics, fire flame movement characteristics, fire smoke characteristics, etc.

[0087] Specifically, Figure 3 A flow chart of fire risk determination processing in the method provided by an embodiment of the present invention is shown.

[0088] Among them, in the preferred embodiment provided by the present invention, the identification of the plurality of internal monitoring data, judging whether there is a fire hazard, and when there is a fire hazard, selecting the fire hazard building and the hazard monitoring data specifically includes the following steps:

[0092] Step S1024, marking the fire protection interconnected building corresponding to the danger monitoring data as a fire protection danger building;

[0093] Specifically, in the step of performing feature matching on the internal monitoring feature data based on the preset fire hazard feature data to determine whether there is a fire hazard, a fire hazard matching degree value is calculated, and based on the fire hazard matching degree value, whether there is a fire hazard is further determined;

[0094] The specific steps for calculating the fire risk matching value are as follows:

[0095] Determining the total number of internal monitoring characteristic values ​​included in the internal monitoring characteristic data and the weight corresponding to each internal monitoring characteristic value;

[0096] Subtracting the internal monitoring characteristic value from the preset fire risk characteristic value to obtain a characteristic difference value, and performing a square operation on the characteristic difference value to obtain an amplified characteristic difference value;

[0097] Multiplying the characteristic difference by a slope parameter to obtain a first intermediate result, and then performing a negative processing on the first intermediate result to obtain a first negative value;

[0098] Taking the first negative value as the power of the exponent, perform an exponential operation on the natural constant to obtain an exponential correction factor;

[0099] The exponential correction factor of the difference is obtained by the exponential correction factor;

[0100] The amplified feature difference is divided by the exponential correction factor of the difference and then the absolute value is taken to obtain the matching degree measurement value;

[0101] Multiply the metric value of each matching degree by the weight corresponding to each internal monitoring feature value to obtain the adjusted metric value;

[0102] All adjusted metric values ​​are accumulated to obtain the fire hazard matching value.

[0103] Furthermore, the building safety fire control method further comprises the following steps:

[0104] Step S103, based on the basic information of the plurality of buildings, collaborative monitoring and analysis is performed on the fire-hazardous buildings, and a plurality of fire-cooperative buildings are selected from the plurality of fire-interconnected buildings.

[0105] In an embodiment of the present invention, based on the basic information of multiple buildings, a collaborative analysis is performed with the fire-hazardous building as the center, and the relative distances and relative orientations of multiple fire-interconnected buildings and the fire-hazardous building are recorded. The multiple relative distances are compared with the preset standard distances, and multiple range collaborative buildings whose relative distances are less than the standard distance are screened out from the multiple fire-interconnected buildings. Then, based on the multiple relative orientations, multiple fire-collaborative buildings whose relative orientations are not blocked are screened out from the multiple range collaborative buildings, so that the fire-hazardous building can be intuitively monitored and photographed.

[0106] Specifically, Figure 4 A flow chart of collaborative monitoring and analysis in the method provided by an embodiment of the present invention is shown.

[0107] Among them, in the preferred embodiment provided by the present invention, the collaborative monitoring and analysis of the fire-hazardous building based on the basic information of the plurality of buildings, and the selection of a plurality of fire-fighting collaborative buildings from the plurality of fire-fighting interconnected buildings specifically include the following steps:

[0108] Step S1031, based on the basic information of the plurality of buildings, collaboratively analyzing the fire-hazardous buildings, and recording the relative distances and relative orientations of the plurality of fire-related interconnected buildings and the fire-hazardous buildings;

[0109] Step S1032, selecting a plurality of range collaborative buildings from the plurality of fire protection interconnected buildings according to the plurality of relative distances;

[0110] Step S1033, selecting a plurality of fire protection cooperative buildings from the plurality of range cooperative buildings according to the plurality of relative directions;

[0111] Specifically, in the step of selecting multiple firefighting cooperative buildings from the multiple range cooperative buildings according to the multiple relative orientations, the comprehensive cooperative score is calculated to evaluate the cooperative effect between the buildings, thereby selecting multiple firefighting cooperative buildings;

[0112] The specific steps for calculating the comprehensive synergy score are as follows:

[0113] Determine the total number of buildings participating in the collaborative analysis;

[0114] Obtain the relative distance and relative orientation between each building and the fire-hazardous building;

[0115] The relative distance is processed by taking the absolute value to obtain the logarithmic value of the distance;

[0116] Determine the sine value of the azimuth based on the relative azimuth calculation, and then correct the sine value of the azimuth to obtain a corrected sine value of the azimuth;

[0117] Multiplying the logarithm of the distance by the sine correction value of the azimuth to obtain a second intermediate result, and dividing the second intermediate result by the exponential correction factor to obtain a coordination contribution value;

[0118] The coordination contribution value of each building is added up and then divided by the total number of buildings to finally get the overall coordination score.

[0119] Furthermore, the building safety fire control method further comprises the following steps:

[0120] Step S104, performing collaborative monitoring planning for the plurality of the fire collaborative buildings, selecting a plurality of collaborative monitoring cameras, and performing collaborative monitoring control on the plurality of the collaborative monitoring cameras to obtain a plurality of collaborative monitoring data.

[0121] In an embodiment of the present invention, by performing relative collaborative analysis on multiple firefighting collaborative buildings, multiple firefighting collaborative buildings' fire approach surfaces close to fire hazardous buildings are selected, and then according to the multiple firefighting approach surfaces, multiple collaborative monitoring cameras located at the corresponding fire approach surfaces are selected from the multiple firefighting collaborative buildings, and a collaborative monitoring instruction is generated and sent to the multiple collaborative monitoring cameras, and then according to the collaborative monitoring instruction, the multiple collaborative monitoring cameras are collaboratively monitored and controlled to obtain multiple collaborative monitoring data.

[0122] Specifically, Figure 5 A flow chart of collaborative monitoring control in the method provided by an embodiment of the present invention is shown.

[0123] Among them, in the preferred embodiment provided by the present invention, the collaborative monitoring planning of the multiple fire collaborative buildings, selecting multiple collaborative monitoring cameras, and collaboratively monitoring and controlling the multiple collaborative monitoring cameras, and obtaining multiple collaborative monitoring data specifically include the following steps:

[0124] Step S1041, performing relative coordination analysis on the plurality of fire coordination buildings, and selecting the fire approach surfaces of the plurality of fire coordination buildings close to the fire risk building;

[0126] Step S1043, generating and sending a collaborative monitoring instruction to the plurality of collaborative monitoring cameras;

[0127] Step S1044, performing collaborative monitoring control on the multiple collaborative monitoring cameras according to the collaborative monitoring instruction, and acquiring multiple collaborative monitoring data;

[0128] Specifically, in the step of selecting a plurality of cooperative monitoring cameras from a plurality of fire cooperative buildings according to a plurality of fire proximity surfaces, a camera selection score is calculated and obtained, and then a plurality of cooperative monitoring cameras are selected based on the camera selection score;

[0129] The specific steps for calculating the camera selection score are as follows:

[0130] Get the total number of cameras and the distance between the cameras and the fire fighting surface;

[0131] Determine the field of view angle influencing factor based on the camera's field of view, and determine the clarity influencing factor based on the camera's resolution;

[0132] Traverse each camera and perform the following calculations for each camera:

[0133] a. For the current camera, the field of view angle influence factor is cubed to obtain a first cubic intermediate result, the clarity influence factor is cubed to obtain a second cubic intermediate result, and then the first cubic intermediate result is added to the second cubic intermediate result and then a square root operation is performed to obtain the camera score result value;

[0134] b. Dividing the field of view angle influence factor by the clarity influence factor to obtain a first ratio, and performing an inverse tangent operation on the first ratio to obtain an inverse tangent value;

[0135] c. Square the distance between the camera and the firefighting surface to obtain the intermediate distance result, and then add 1 to the intermediate distance result to obtain the distance impact value;

[0136] d. Use the camera's score result value as the numerator and the distance impact value as the denominator to perform a division operation, and multiply the result by the arc tangent value to obtain the camera's score contribution value;

[0137] The score contribution value of each camera is accumulated to obtain the camera selection score.

[0138] Furthermore, the building safety fire control method further comprises the following steps:

[0140] In an embodiment of the present invention, multi-source monitoring feature data is obtained by performing comprehensive feature recognition and recording on dangerous monitoring data and multiple collaborative monitoring data, and then feature matching is performed on the multi-source monitoring feature data based on preset fire spread feature data to determine whether there is fire spread. Specifically: if the feature matching is successful, it is determined that there is fire spread. At this time, the fire spread area and fire spread direction are determined, and then the fire spread control is performed according to the fire spread area and fire spread direction; if the feature matching is unsuccessful, it is determined that there is no fire spread.

[0141] It is understandable that the fire spread characteristic data includes smoke diffusion speed, smoke flow direction, delay density, external wall flame direction, etc.

[0142] It is understandable that fire spread control, automatic fire alarm to disperse the crowd, automatic sprinkler fire extinguishing, automatic smoke exhaust treatment, reasonable planning of evacuation routes and notification, etc.

[0143] Specifically, Figure 6 A flow chart of fire spread analysis and control in the method provided by an embodiment of the present invention is shown.

[0144] Among them, in the preferred embodiment provided by the present invention, the fire spread analysis of the fire-hazardous building based on the danger monitoring data and the plurality of coordinated monitoring data and the fire spread control specifically comprises the following steps:

[0147] Step S1053, when there is fire spreading, determining the fire spreading area and fire spreading direction;

[0148] Step S1054, performing fire spread control according to the fire spread area and the fire spread direction;

[0149] Specifically, in the step of performing feature matching on the multi-source monitoring feature data based on the preset fire spread feature data to determine whether there is fire spread, by calculating the fire spread assessment value, and then determining whether there is a potential impact of fire spread based on the fire spread assessment value;

[0150] The specific steps for calculating the fire spread assessment value are as follows:

[0151] Determine the time frame of fire spread;

[0152] By analyzing historical data, we can obtain the regional spread influence coefficient and directional spread influence coefficient;

[0153] At each moment within the time range of fire spread, the rate of change of the spread area over time is calculated to obtain the spread change rate;

[0154] The spreading change rate is cubed to obtain the cube value of the spreading change rate;

[0155] Based on the actual spreading area at the current moment, the initial spreading area is subtracted, and then the difference is squared to obtain the amplified spreading change value;

[0156] The impact value of the spreading area is obtained based on the spreading change rate and the amplified spreading change value;

[0157] Within the time range of fire spread, the cosine value of the spreading direction angle at the current moment is calculated, and the cosine value of the spreading direction angle is squared to obtain the square value of the cosine;

[0158] The influence value of the spreading direction is calculated based on the square value of cosine;

[0159] The regional spread influence coefficient is used to weight the spread area influence value to obtain the weighted spread area influence value, and the directional spread influence coefficient is used to weight the spread direction influence value to obtain the weighted spread direction influence value;

[0160] The weighted spread area impact value and the weighted spread direction impact value are summed to obtain the spread impact value, and then the spread impact value is accumulated within the time range of fire spread to obtain the fire spread assessment value.
