[0060] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0061] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0062] In the currently known high-rise fire trucks of the same type, when performing firefighting operations, the operator operates the boom to move the water cannon to the vicinity of the fire point, and controls the water cannon to spray water to extinguish the fire through the operator's visual observation or on-site monitoring video. This not only places high operating requirements on the operator, but also makes it impossible to accurately determine the fire location, and the firefighting efficiency is extremely low.

[0063] In view of this, if Figure 3 and 4 As shown, the first exemplary embodiment of the present application provides a fire extinguishing control method for a fire-lift truck, the fire extinguishing control method comprising the following steps:

[0064] S100: Determine the range of the fire area 5 and divide the fire area 5 into a plurality of fire zones;

[0065] S200: Obtaining an infrared thermal image of the fire area 5;

[0066] S300: Determine the fire point zone 501 with the highest temperature among the multiple fire zones according to the infrared thermal image;

[0067] S400: Obtaining the fire extinguishing distance between the water cannon 1 of the aerial fire fighting vehicle and the fire point zone 501;

[0068] S500: Determine the water spraying pressure and water spraying angle of the water monitor 1 according to the fire extinguishing distance.

[0069] In step S100, the fire area 5 refers to the plane where the burning object is located, which can be a horizontal plane, a vertical plane, an inclined plane, etc., and the present application does not limit this. In the present embodiment, it is mainly aimed at the floor plane in the building. Determining the scope of the fire area 5 refers to determining the boundary of the fire area 5. For example, if the fire occurs in a closed room of a building, then the scope of the fire area 5 is composed of the walls of the closed room. By determining the scope of the fire area 5, the fire area and the orientation of the fire area 5 can be determined. When the scope of the fire area 5 is known, the actual area of ​​the fire area 5 can be displayed, and the fire area 5 can be divided into multiple fire partitions, for example, in a grid shape.

[0070] In step S200, infrared thermal imaging technology can be used to obtain an infrared thermal image of the fire area 5. In step S300, combined with the partitioning of the fire area 5, the ignition point partition with the highest temperature among the multiple fire partitions can be determined from the infrared thermal image. When the orientation of the ignition point partition 501 is known, in step S400, the distance between the water monitor 1 and the ignition point partition 501 is detected, and this is used as the fire extinguishing distance of the water monitor 1. In step S500, the water spraying pressure and the water spraying angle of the water monitor are determined by the water pump outlet pressure and the water monitor placement angle, respectively. When the fire extinguishing distance is known, the appropriate water pump outlet pressure and water monitor placement angle can be determined based on the empirical parameters of the water monitor, so that the water flow can be accurately sprayed to the ignition point partition 501.

[0071] It can be seen from the above steps S100 to S500 that the fire extinguishing control method of this exemplary embodiment innovatively uses infrared thermal imaging technology to perform temperature detection on the fire area 5, and identifies the fire point partition 501 with the highest temperature among multiple fire partitions, thereby avoiding the problem of being unable to visually identify the fire point due to smoke obstruction, and more accurately determining the position of the fire point. When the orientation of the fire point partition 501 is determined, the distance between the water monitor 1 and the fire point partition 501 is detected, and the water spraying pressure and water spraying angle of the water monitor 1 are adjusted accordingly, so that water can be accurately sprayed to the fire point position, so as to achieve the purpose of rapid fire extinguishing and reducing fire losses.

[0072] Generally, the enclosed rooms in buildings are rectangular spaces. Figure 1 and Figure 2 , when the fire area 5 is a rectangular area ABCD, step S100 may include:

[0073] Step S101: obtaining the distances between the water monitor 1 and any three endpoints of the fire area 5;

[0074] Step S102: Determine the range of the fire area 5 according to the distances between the three endpoints.

[0075] In step S101, the distances between the three endpoints can be as follows: Figure 2 L1, L2 and L4 are shown, where L1 is the distance from the water monitor point E to the end point A, L2 is the distance from the water monitor point E to the end point D, and L4 is the distance from the water monitor point E to the end point C. When L1 and L2 are known and the rotation angle ∠AED of the water monitor is θ, the length L of the edge AD of the fire area 5 can be obtained according to the cosine theorem, where the length L of the edge AD satisfies: L1 2 +L2 2 -2 L1 L2cosθ=L 2; When L2 and L4 are known and the rotation angle ∠CED of the water monitor is α, the length L5 of the edge CD of the fire area 5 can be obtained according to the cosine theorem, where the length L5 of the edge CD satisfies: L2 2 +L4 2 -2 L2 L4cosα=L5 2 .

[0076] Therefore, in step S102 , according to the detection result of step S101 , the range of the fire area 5 , that is, the area of ​​the fire area 5 , and the orientation of the fire area 5 relative to the water monitor 1 can be determined.

[0077] Since it is impossible to determine the type of the burning object by directly observing the burning object under the cover of smoke, in an optional or preferred embodiment, the fire extinguishing control method further includes:

[0078] Step S300': obtaining an object model of the burning object in the fire area 5 according to the infrared thermal image;

[0079] Step S400 ′: determining the estimated object type of the combustion object according to the object model.

[0080] Specifically, since the infrared thermal image is a two-dimensional image, it can not only distinguish different temperatures by rendering different colors, but also display the contour model of objects with a temperature difference from the external environment. To this end, after executing step S200 to obtain the infrared thermal image of the fire area 5, the infrared thermal image is observed by the operator with the naked eye or analyzed by the processing equipment, from which the object model of the burning object located in the ignition point partition 501, that is, the contour model of the burning object, can be obtained, and then the object type of the burning object is obtained by manual judgment or comparison and analysis by the processing equipment based on the object model, and this is used as the estimated object type. In the case of knowing the estimated object type, for example, when it is judged that the burning object is an object type that is not suitable for fire extinguishing with water, an inert gas such as nitrogen can be selected for fire extinguishing; when it is judged that the burning object is an object type that is suitable for fire extinguishing with water, water or foam can be selected for fire extinguishing.

[0081] In order to improve the accuracy of object type recognition of the burning object, the fire extinguishing control method of this exemplary embodiment further includes:

[0082] Step S500': determining the estimated gas composition generated by the combustion object according to the estimated object type;

[0083] Step S600': obtaining the actual gas composition in the fire area 5 and comparing the actual gas composition with the estimated gas composition;

[0084] Step S700 ′: when it is determined that the actual gas composition is consistent with the estimated gas composition, determining that the estimated object type is the actual object type of the combustion object.

[0085] In step S500', when the estimated object type is known, for example, when the estimated object type of the burning object is a book, the estimated gas composition can be determined as carbon dioxide; when the estimated object type of the burning object is plastic, the estimated gas composition can be determined as hydrogen chloride. In step S600', the actual gas composition in the fire area 5 can be obtained by the gas detection device, and the actual gas composition and the estimated gas composition can be compared by manual comparison or processing equipment analysis. In step S700', if the comparison results are consistent, it can be determined that the estimated object type is the actual object type. For example, when the estimated object type is a book, the actual object type is a book. If the comparison results are inconsistent, the actual object type can be determined based on the actual gas composition.

[0086] Furthermore, the fire extinguishing control method of this exemplary embodiment also includes:

[0087] Step S800': determining the fire extinguishing medium to be selected according to the actual object type.

[0088] Specifically, if an inert gas such as nitrogen is selected as the fire extinguishing medium, the nitrogen supply assembly can be controlled manually or by processing equipment to produce nitrogen, and pressurized by an air pump, and the nitrogen is transported to the nitrogen gun muzzle through a pipeline to be sprayed into the fire area 5. When the nitrogen concentration in the fire area 5 is greater than a certain value, the combustion materials in the fire area 5 will be extinguished due to lack of oxygen.

[0089] If water is selected as the fire extinguishing medium, the water monitor assembly can be controlled by executing steps S100 to S500 to adjust the water spraying pressure and angle of the water monitor 1, and targeted fire extinguishing can be performed towards the fire point partition 501, thereby improving the fire extinguishing accuracy and efficiency.

[0090] The second exemplary embodiment of the present application provides a fire extinguishing system for an elevated fire truck, which can execute the fire extinguishing control method for an elevated fire truck. Therefore, each embodiment of the fire extinguishing system described below can obviously obtain the technical effects brought by each corresponding embodiment of the above method, so for each embodiment described below, only the additional technical effects brought by its structural features are described to avoid repeating the previous content.

[0091] like Figures 1 to 3As shown, the fire extinguishing system for the elevated fire truck of this exemplary embodiment includes a water cannon assembly, a radar ranging device 2, an infrared camera module 3 and a processing device. The water cannon assembly includes a water cannon 1 arranged on the arm of the elevated fire truck; the radar ranging device 2 is arranged on the water cannon 1 and is used to detect the distance between the water cannon 1 and the fire area 5; the infrared camera module 3 is arranged on the water cannon 1 and is used to take an infrared thermal image of the fire area 5; the processing device is respectively connected to the water cannon 1 assembly, the radar ranging device 2 and the infrared camera module 3 and is configured as follows:

[0092] Control the radar distance measuring device 2 to detect the distance between the water monitor 1 and the fire area 5;

[0093] Determine the range of the fire area 5 according to the distance between the water monitor 1 and the fire area 5, and divide the fire area 5 into a plurality of fire zones;

[0094] Controlling the infrared camera module 3 to obtain an infrared thermal image of the fire area 5;

[0095] Determine the fire point zone 501 with the highest temperature among the multiple fire zones according to the infrared thermal image;

[0096] Control the radar distance measuring device 2 to detect the fire extinguishing distance between the water monitor 1 and the fire point partition 501;

[0097] The water spraying pressure and water spraying angle of the water monitor 1 are controlled according to the fire extinguishing distance.

[0098] In this exemplary embodiment, after detecting the distance between the water cannon 1 and the various boundaries of the fire area 5, the radar ranging device 2 can send the distance data to the processing equipment. The processing equipment can establish a first coordinate system (X1, Y1) according to the installation position of the radar ranging device 2, and combine the above distance data to derive the range of the fire area 5, that is, the area of ​​the fire area 5, and the coordinates of each point in the fire area 5 in the first coordinate system (X1, Y1). In other words, the coordinates of multiple fire partitions in the first coordinate system (X1, Y1) can be obtained.

[0099] After the infrared camera module 3 obtains the infrared thermal image including the fire area 5, it can send the infrared thermal image to the processing device. The processing device can establish a second coordinate system (X2, Y2) according to the installation position of the infrared camera module 3 and the image resolution of the infrared thermal image, and determine the pixel point showing the highest temperature in the infrared thermal image as the fire point by analyzing the pixel point, and obtain the coordinates of the fire point in the second coordinate system (X2, Y2).

[0100] Furthermore, the processing device can obtain a corresponding functional relationship based on the coordinates of the multiple fire zones of the fire area 5 in the second coordinate system (X2, Y2) and the coordinates of the multiple fire zones in the first coordinate system (X1, Y1). Therefore, when the coordinates of the fire point in the second coordinate system (X2, Y2) are known, the coordinates of the fire point zone 501 in the first coordinate system (X1, Y1) can be calculated according to the above functional relationship, thereby calculating the distance between the water monitor 1 and the fire point zone 501.

[0101] By using the above method to calculate the distance between the water monitor 1 and the fire point partition 501, that is, the fire extinguishing distance of the water monitor 1, it is possible to avoid errors in the distance detection of the fire point measured by the infrared camera module 3 by the radar ranging device 2 due to the installation position deviation between the radar ranging device 2 and the infrared camera module 3.

[0102] In an optional or preferred embodiment, when the fire area 5 is a rectangular area, the processing device is configured as follows:

[0103] Control the radar distance measuring device 2 to detect the distances between the water monitor 1 and any three endpoints of the fire area 5;

[0104] The scope of the fire area 5 is determined based on the distances of the three endpoints.

[0105] like Figure 2 In the embodiment shown, the radar ranging device 2 can be used to detect the distance from the water monitor 1 to the three end points A, C, and D in the rectangular area, so as to determine the area of ​​the rectangular area ABCD and the distance between each point in the rectangular area ABCD and the water monitor 1, so that a first coordinate system with the radar ranging device 2 as the origin can be established in the processing equipment, and then the coordinates of the rectangular area ABCD in the first coordinate system can be obtained.

[0106] In an optional or preferred embodiment, the processing device is preset with an object model database including a plurality of combustible object models, and the processing device is further configured to:

[0107] Obtaining an object model of the burning object in the fire area 5 according to the infrared thermal image;

[0108] The object model is compared with a plurality of combustible object models in an object model database to determine an estimated object type of the combustible object.

[0109] In this exemplary embodiment, the combustible model is a two-dimensional model of an object. When the processing device receives the infrared thermal image, it can obtain the contour image of the object at the highest temperature point from the infrared thermal image, and use the contour image of the object as the object model of the combustible object to compare it with multiple combustible models in the object model database one by one. When the comparison is successful, the estimated object type of the combustible object can be determined; when the comparison fails, manual judgment is performed, and the object model database is manually expanded later, that is, the estimated object type manually identified this time is added to the object model database to be used for the next fire extinguishing.

[0110] In an optional or preferred embodiment, the fire extinguishing system further comprises a gas detection device 4 for detecting the actual gas composition in the fire area 5, and the processing device communicates with the gas detection device 4 and is configured as follows:

[0111] Determining the estimated gas composition produced by the combustion object based on the estimated object type;

[0112] Controlling the gas detection device 4 to detect the actual gas composition in the fire area;

[0113] comparing the estimated gas composition with the actual gas composition;

[0114] When it is determined that the actual gas composition is consistent with the estimated gas composition, the estimated object type is determined to be the actual object type of the combustion object.

[0115] In this exemplary embodiment, after determining the estimated object type, the processing equipment can judge the estimated gas composition produced by the combustion of the combustible material of the estimated object type based on a pre-established database. After the gas detection device 4 detects the actual gas composition in the fire area 5, the data of the actual gas composition can be sent to the processing equipment. The processing equipment can compare the actual gas composition with the estimated gas composition. If the comparison result is consistent, it is determined that the estimated object type is the actual object type, that is, the estimated object type is accurate; if the comparison result is inconsistent, manual judgment is performed and the database is expanded.

[0116] In summary, the present application can verify the object model in the infrared thermal image and the gas composition in the air to confirm the type of the combustion object.

[0117] In an optional or preferred embodiment, the fire extinguishing system includes a plurality of fire extinguishing medium supply assemblies, the plurality of fire extinguishing medium supply assemblies including a water monitor assembly and a nitrogen supply assembly, and the processing device communicates with the plurality of fire extinguishing medium supply assemblies and is configured as follows:

[0118] Determine the fire extinguishing medium to be selected according to the actual object type;

[0119] According to the selected fire extinguishing medium, control the operation of the corresponding fire extinguishing medium supply assembly.

[0120] In this exemplary embodiment, after determining the actual object type, the processing device determines which fire extinguishing medium should be used according to the actual object type, such as water or nitrogen. When it is determined that water is used as the fire extinguishing medium, the water monitor assembly is controlled to operate so that the water monitor 1 sprays water toward the fire point partition 501; when it is determined that nitrogen is used as the fire extinguishing medium, the nitrogen supply assembly is controlled to operate so that the nitrogen nozzle sprays nitrogen toward the entire fire area 5. Of course, the nitrogen supply assembly is more suitable for use when the fire area 5 is a confined space.
