Description

Technical Field

[0001] The present invention relates to the field of fire protection technology, and more particularly, to a method and system for assisting in formulating fire protection disposal strategies based on drone relay. Background Art

[0002] In fire emergency rescue work, rapid and effective fire extinguishing operations are crucial for reducing casualties and property losses. On the way to the fire scene after receiving a fire alarm task, firefighters urgently need to obtain specific fire situation information in advance, including the scale of the fire, the direction of fire spread, the structure of the burning building, the types of combustible materials, etc. This detailed fire situation information can help firefighters formulate targeted fire protection disposal strategies before arriving at the scene, such as reasonably deploying fire trucks and equipment, planning fire extinguishing routes, determining fire extinguishing tactics, etc., thus greatly improving the efficiency and success rate of fire extinguishing and rescue operations. However, the current status of fire protection technology has significant limitations. Most of the existing fire warning and information acquisition systems can only provide basic information such as the location of the fire after the fire occurs, and cannot transmit specific fire situation details to the firefighters on their way to the scene in real time, comprehensively and accurately. Traditional monitoring means are difficult to provide key data on the dynamic changes at the fire scene to firefighters on their way, making the understanding of the actual fire situation by firefighters extremely limited before arriving at the scene. They often have to rely on experience estimates, which undoubtedly increases the difficulty and risk of fire extinguishing and rescue operations in complex and changeable fire scenarios, seriously affecting the timeliness and effectiveness of fire protection work.

[0003] In view of this, it is extremely urgent to develop a technology that can enable firefighters to obtain specific fire situation information in advance on their way to the fire scene and formulate fire protection disposal strategies accordingly. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required in the embodiments. It should be understood that the following drawings only show some embodiments of the present invention, and therefore should not be regarded as limiting the scope. For those of ordinary skill in the art, other related drawings can be obtained based on these drawings without creative efforts.

[0019] Figure 1 is a schematic flowchart of a method for assisting in formulating a fire fighting strategy based on drone relay according to an embodiment of the present invention.

[0020] Figure 2 is a schematic structural diagram of a system for assisting in formulating a fire fighting strategy based on drone relay according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0021] 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, a method for assisting in formulating a fire disposal strategy based on drone relay in an embodiment of the present invention includes the following steps: S10, the UAV located at the fire point establishes a communication connection with the video monitoring system of the fire point to obtain a set of monitoring videos before and after the fire occurs.

[0023] In this step, a video surveillance system is deployed inside the fire point, which includes multiple cameras of various types that are distributed and a data management system located in the monitoring center. At the same time, the above-mentioned drone is also set up outside the fire point. The drone can be a drone specially deployed at the fire point, which can be deployed in a dedicated facility outside the building; it can also be a fire-specific drone with special permissions, which is carried and kept by relevant personnel. When the relevant personnel find the fire point, they can manually release the drone.

[0024] When the fire alarm sends out a fire alarm signal, the data management system of the video surveillance system will start the wireless connection mode, and the drone will be activated and take off (or released manually). At this time, the drone and the video surveillance system will realize wireless communication connection, and can obtain the surveillance video before and after the fire. For example, in a shopping mall fire, the video surveillance system has previously recorded the distribution of people in the mall, the layout of stores, etc. After the drone obtains these videos, the firefighters can understand the internal conditions of the mall before and after the fire, provide reference for subsequent rescue planning, and know the key information such as the location of trapped people and the surrounding environment of the fire source.

[0025] S20, the drone captures a live video of the fire point based on the established patrol route, cuts and splices the monitoring video and the live video to obtain a fire video.

[0026] In this step, after the drone takes off, it can obtain the patrol path stored internally and shoot live video according to the planned patrol path. For example, in a high-rise fire, the drone flies around the high-rise building to shoot real-time conditions such as the fire and smoke spread from different angles. The above patrol path is pre-planned according to the layout of the building at the fire point and stored in the memory of the drone; or, the patrol path is the path that the above-mentioned relevant personnel control the drone to actually fly through the remote control.

[0027] The drone uses built-in video processing software to identify key content in the previously obtained surveillance video and the current live video, and performs cutting and splicing operations, capable of integrating a coherent and comprehensive fire video, enabling firefighters to see the development process of the fire from its occurrence to the present, and clearly grasping key information such as the scale of the fire and the direction of the fire spread.

[0028] It should be noted that after the fire develops to a certain extent, the video surveillance system will gradually collapse and can no longer transmit surveillance videos to the drone. At this time, a fire video can be generated based on the live video captured by the drone.

[0029] S30, the drone communicates with the fire control center to determine the fire truck corresponding to this fire point and its communication code, establishes a communication connection with this fire truck based on the communication code, and sends the fire video to this fire truck to assist the relevant personnel in this fire truck to formulate a fire fighting disposal strategy in advance.

[0030] In this step, the drone communicates with the fire control center, determines the fire truck responsible for this fire point and its communication code, and then establishes a connection with it, and sends the integrated fire video over. In this way, the firefighters in this fire truck can, on the way, reasonably allocate fire trucks and equipment according to the fire situation in the video, plan the fire fighting route based on the direction of the fire spread, and determine the fire fighting tactics according to the type of burning substances, greatly improving the efficiency and success rate of fire fighting and rescue operations.

[0031] The solution of the present invention uses a drone to obtain and relay the on-site fire situation of the fire point, enabling the firefighters in the fire truck to understand the fire situation in advance on the way to the fire point and formulate a suitable fire fighting disposal strategy in advance, which is very beneficial for efficient fire fighting and can significantly improve the fire fighting effect.

[0032] In some examples, the drone located at the fire point establishes a communication connection with the video surveillance system at this fire point, including: After the drone located at the fire point receives the fire alarm signal sent by the fire alarm, it analyzes and obtains the signal ID and connection key from this fire alarm signal; among them, the signal ID is associated with the video surveillance system at this fire point; The drone scans to obtain the wireless signal corresponding to the signal ID, and establishes a communication connection with this wireless signal based on the connection key, that is, completes the establishment of a communication connection with the video surveillance system at this fire point.

[0033] In this embodiment, when a fire breaks out, the fire alarm monitors the fire and sends out a fire alarm signal. When the drone receives this fire alarm signal in the low-power monitoring mode, it switches to the working state. Then, the signal ID and connection key are parsed from the fire alarm signal. Among them, the signal ID is the ID of the wireless signal of the video monitoring system deployed in the area where the fire alarm that sent out the fire alarm signal belongs. After receiving the fire alarm signal, the video monitoring system turns on the wireless signal.

[0034] Subsequently, the drone actively scans the surrounding environment to search for the wireless signal corresponding to the signal ID parsed previously. Once a matching wireless signal is scanned, it immediately uses the simultaneously obtained connection key to establish a communication connection with this wireless signal. When this connection is established, the drone can smoothly obtain the monitoring videos before and after the fire from the video monitoring system.

[0035] In some examples, the obtaining of a set of monitoring videos before and after the fire includes: The drone sends a video acquisition request to the video monitoring system; The video monitoring system parses the fire location information from the fire alarm signal, retrieves the fire record corresponding to the fire location information; parses the number of fire types and the number of fire records from the fire record, and matches a target range according to the number of fire types and the number of fire records; The video monitoring system acquires a set of the monitoring videos before and after the fire corresponding to the target range and feeds back the monitoring videos to the drone.

[0036] In this embodiment, after the drone establishes a communication connection with the video monitoring system, it sends a video acquisition request to the video monitoring system. At this time, the video monitoring system receives the request and then actively acquires a set of monitoring videos of the fire occurrence area before and after the fire. This set of monitoring videos should at least contain key information such as the cause of the fire, the type of the ignited item, and other flammable items stacked in the fire area. However, this set of monitoring videos should also be as concise as possible and not too long, otherwise the drone will need more time to process, which is not conducive to providing the fire situation video to the firefighters in a timely manner.

[0037] To address the above problems, the present invention sets the video monitoring system to first parse the fire location information from the fire alarm signal, which is the key to locating the fire occurrence site. Then, the video monitoring system further retrieves the fire record corresponding to the fire location information from the information stored in itself. These records contain the number of fire types and the number of fire records. The video monitoring system analyzes these two key data and accordingly matches a target range of an appropriate size. Finally, the video monitoring system screens a set of monitoring videos before and after the fire corresponding to this target range.

[0038] In some examples, the matching of the target range according to the number of fire types and the number of fire records includes: Calculating the ratio of the number of fire types to the number of fire records, and matching the target range according to the ratio; wherein, the target range is positively correlated with the ratio.

[0039] In this embodiment, the fire in the fire occurrence area may be caused by improper construction or short circuit in its own area, or may be caused by a fire in the adjacent area. For example, after a fire occurs in the adjacent area, a small-scale explosion occurs (if there is no fire alarm installed in the adjacent area, the video monitoring system will not actively retrieve the monitoring video of the adjacent area), causing the fire-carrying items to fly into this own area, thus triggering a fire. This information is also necessary for the firefighters, so it is necessary to adjust the retrieval range of the monitoring video.

[0040] Specifically, the present invention sets the size of the target range according to the ratio of the number of fire types to the number of fire records. Among them, when the ratio is larger, it indicates that the cause of the fire in this own area is more complex, and there is a greater probability of being affected by the adjacent area and causing a fire. At this time, the target range is set larger so that the retrieved monitoring video includes these adjacent areas; otherwise, the target range is set smaller, which can reduce the volume of the retrieved monitoring video.

[0041] In some examples, the method further includes: The drone determines whether the real-time fire situation at the fire point reaches a preset condition based on the fire video. If so, it stops generating and sending the new fire video to the fire truck; wherein, the preset condition means that all the personnel passages at the fire point have reached the preset fire level; If not, it continues to generate the new fire video and send it to the fire truck.

[0042] In this embodiment, after the drone obtains and integrates the fire video, it also analyzes and judges the latest situation of the real-time fire. A preset condition is set in advance. The preset condition focuses on whether all the personnel passages at the fire point reach or exceed the preset fire level. This level setting is closely related to the safe evacuation of personnel. For example, indicators such as the smoke concentration in the passage and the degree of fire spread to the passage will be taken into consideration.

[0043] Among them, a model for semantic understanding of video content of a fire situation video can be set. This model comprehensively evaluates the actual fire situation characteristics of each personnel passage included in the fire situation video (such as the area of the passage covered by the flame and the reduction in visibility caused by the smoke) to determine whether it reaches a preset fire situation level. If so, it is determined that the preset condition is satisfied. This model is, for example, a model constructed based on general large models (DeepSeek, GPT, etc.).

[0044] If the latest situation of this fire point has reached the preset condition or above, it indicates that the fire situation has reached a relatively serious level. Subsequently, the nature of the fire is essentially the same, and the value of newly generated fire situation videos for firefighters to adjust rescue strategies is limited. Therefore, the drone will stop generating new fire situation videos at this time and will no longer send them to the fire truck, so as to avoid unnecessary data transmission and reduce the occupation of communication resources, enabling the fire communication link to process other key information more efficiently.

[0045] In this way, firefighters can always obtain the latest and key fire situation dynamics on the way to the scene, so that they can flexibly and accurately adjust fire fighting disposal strategies based on the most accurate information before arriving at the scene, further improving the success rate and safety of fire fighting and rescue operations.

[0046] As Figure 2 shown, the embodiment of the present invention also discloses a system for assisting in formulating fire fighting disposal strategies based on drone relay, including a processing module and a storage module. The processing module is connected to the storage module; among them, the storage module is used to store computer program codes; the processing module is used to execute the following steps by calling the computer program codes in the storage module: The drone located at the fire point establishes a communication connection with the video monitoring system at this fire point to obtain a set of monitoring videos before and after the fire occurs; The drone takes a live video of this fire point based on the formulated patrol path, and performs cutting and splicing processing on the monitoring video and the live video to obtain a fire situation video; The drone communicates with the fire control center to determine the fire truck corresponding to this fire point and its communication code, establishes a communication connection with this fire truck based on the communication code, and sends the fire situation video to this fire truck to assist the relevant personnel of this fire truck in formulating fire fighting disposal strategies in advance.
