Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In case of fire, in order to reduce loss and improve disaster relief efficiency, firefighters need to make an effective disaster relief strategy. However, the existing fire fighting system only alarms according to the fire situation, and cannot effectively acquire fire fighting information in a fire scene, so that fire fighters are not facilitated to make effective fire fighting strategies. Especially for places with complex terrains such as superstores or large office buildings, the grasp of effective fire-fighting information has a decisive role in reducing property loss and rescuing people suffering from disasters.

In view of this, the present application provides a fire fighting system, referring to fig. 1, including:

an image acquisition device 101 and a server 102;

the image acquisition device 101 is configured to acquire image data of a designated monitoring area, and send the image data of the designated monitoring area to the server 102, where the designated monitoring area includes a fire fighting access;

the server 102 is configured to obtain image data of the designated monitoring area; analyzing the image data of the designated monitoring area to obtain the environmental information of the fire fighting access; and determining whether the fire fighting access is available according to the environment information of the fire fighting access, wherein the environment information of the fire fighting access comprises the flame information and the occupation information of the fire fighting access.

The image capturing device 101 may be specifically a camera or the like, and in order to cope with a fire scene, the image capturing device 101 may be made of a high temperature resistant material, and a fireproof casing may be added outside the image capturing device 101. In one possible embodiment, in order to ensure communication between the image capturing device 101 and the server 102, the image capturing device 101 may communicate with the server 102 by using both wired and wireless modes, and when the wired line communication is normal, the image capturing device 101 communicates with the server 102 by using the wired line; when the wired line communication is abnormal, the image capturing apparatus 101 communicates with the server 102 by using a wireless communication method.

The image capturing apparatus 101 captures image data of a designated monitoring area (i.e., a monitoring area including a fire passage) and transmits the image data to the server 102. After the server 102 acquires the image data, the image data is analyzed to obtain flame information and occupation information of the fire fighting access, and the server 102 determines whether the fire fighting access is available according to the environment information (i.e., the flame information and the occupation information) of the fire fighting access. The flame information of the fire passageway characterizes a degree of fire of the fire passageway, e.g., the flame information may be an area of the fire passageway occupied by a flame. Occupancy information for the fire passageway characterizes the extent to which the fire passageway is blocked, e.g., occupancy information may be the area of the fire passageway occupied by the blockage. Of course, in the actual analysis process, there may be a case where no flame or blockage is included in the image data of the fire fighting access, and accordingly, the flame information represents no flame or the occupancy information represents no blockage.

The server 102 may analyze the image data using a related computer vision technique to obtain the flame information and occupancy information of the fire protection pathway. In one possible implementation, the server 102 analyzes the image data by using a pre-trained deep learning algorithm to determine a flame region and an occupation region in the fire fighting access, so as to obtain the flame information and the occupation information of the fire fighting access. The step of training the deep learning algorithm in advance may include: inputting the sample image marked with the flame into a preset neural network for training, and converging to obtain a flame recognition network; inputting the sample image marked with the blocking object into a preset neural network for training, and obtaining a blocking object identification network after convergence; and combining the flame recognition network and the blockage recognition network to obtain a pre-trained deep learning algorithm.

The server 102 may also obtain flame information and occupancy information of the fire passage by using methods such as feature analysis, for example, the server 102 performs foreground image extraction on the image data to obtain a foreground image of the image data, and then compares image features in the foreground image with preset flame features and preset obstruction features by using a feature comparison method to determine a flame region and a blockage region, thereby obtaining the flame information and the occupancy information.

In order to reduce the processing pressure of the server 102, optionally, an area to be shielded of the image data is set in the server 102, and when the server 102 analyzes the image data, the area outside the area to be shielded in the image data is specifically used for analyzing. Optionally, the server 102 sets a region to be detected, and the server 102 is specifically configured to analyze the region to be detected in the image data when analyzing the image data. The server 102 analyzes only the area to be detected, which can save system resources of the server 102 and improve the analysis speed. Specifically, the areas to be shielded and the areas to be detected in the image data may be set as shown in fig. 2a and fig. 2b, respectively.

After acquiring the flame information and the occupation information of the fire fighting access, the server 102 judges whether the fire fighting access is available according to the flame information and the occupation information, and judges that the fire fighting access is available when the flame information and the occupation information both meet preset available conditions. In one possible implementation, the server 102 determines a flame occupation area ratio and a blockage occupation area ratio in the fire fighting tunnel according to the flame information and the occupation information of the fire fighting tunnel, and determines that the fire fighting tunnel is available when the flame occupation area ratio is smaller than a preset flame area threshold and the blockage occupation area ratio is smaller than a preset blockage area threshold; otherwise, judging that the fire fighting access is unavailable. The preset flame area threshold and the preset blockage area threshold can be set according to actual conditions, and the preset flame area threshold and the preset blockage area threshold are positively correlated with the area of the fire fighting channel. For example, the preset flame area threshold may be set to 3% -5%, and the preset obstruction area threshold may be set to 40% -60%.

In a possible implementation manner, the server 102 may further predict a fire spreading condition according to the flame information by using a preset fire spreading algorithm, so as to obtain the flame information of the fire fighting access after the specified time period, and further determine whether the fire fighting access is available after the specified time period. The preset fire spreading algorithm may be any fire spreading algorithm in the related art, and is not specifically limited herein.

It can be understood that when there are multiple fire fighting access, multiple image capturing devices 101 may be provided, and the image data sent by the image capturing devices 101 may include fire fighting access identifiers or image capturing device identifiers, so as to facilitate the server 102 to distinguish the image data of each fire fighting access. Server 102 may determine whether each fire escape is available separately.

In the embodiment of the application, the image data of the fire fighting channel is acquired by the image acquisition equipment, the image data is analyzed by the server, and the flame information and the occupation information of the fire fighting channel are determined, so that whether the fire fighting channel is available or not is determined, and more fire fighting information in a fire scene is acquired. And fire fighters can fully know whether each fire fighting access is available or not when making a disaster relief strategy, and the unavailable fire fighting access can be effectively avoided when considering the disaster relief strategy, so that the fire fighters can be facilitated to make the disaster relief strategy.

In many cases, the smoke is the most main cause of casualties in the fire, optionally, the environmental information of the fire fighting access further includes smoke information of the fire fighting access, see fig. 3, and the fire fighting system of the embodiment of the present application further includes: a smoke sensing device 103;

The environmental information of the fire fighting access also includes smoke information of the fire fighting access, and the server 102 analyzes the smoke information, the flame information and the occupancy information of the fire fighting access to determine whether the fire fighting access is available. For example, the server 102 determines the ratio of the flame occupied area and the ratio of the blockage occupied area in the fire fighting tunnel according to the flame information and the occupancy information of the fire fighting tunnel, and determines the smoke concentration in the fire fighting tunnel according to the smoke information of the fire fighting tunnel. When the occupied area proportion of the flame is smaller than a preset flame area threshold, the occupied area proportion of the obstruction is smaller than a preset obstruction area threshold, and the smoke concentration is smaller than a preset concentration threshold, judging that the fire fighting channel is available; otherwise, judging that the fire fighting access is unavailable. The preset concentration threshold may be set according to an actual fire-fighting standard, and is not specifically limited herein.

In one possible embodiment, the smoke information may include the type of smoke and the concentration of each type of smoke, different concentration thresholds may be set for different types of smoke, and each concentration threshold may be set according to an actual fire protection standard. And when the concentration of each type of smoke is smaller than the corresponding concentration threshold, judging that the smoke concentration is smaller than a preset concentration threshold, otherwise, judging that the smoke concentration is larger than the preset concentration threshold.

In the embodiment of the application, when determining whether the fire fighting access is available, smoke information is also considered, the safety performance of the available fire fighting access can be further provided, and the fire fighting personnel can conveniently make a disaster relief strategy.

The environmental information of the fire fighting access also includes temperature information of the fire fighting access, and the server 102 analyzes the temperature information, flame information and occupancy information of the fire fighting access to determine whether the fire fighting access is available. For example, the server 102 determines the flame occupation area ratio and the blockage occupation area ratio in the fire fighting access according to the flame information and the occupation information of the fire fighting access, and determines the access temperature in the fire fighting access according to the temperature information of the fire fighting access. When the occupied area ratio of the flame is smaller than a preset flame area threshold, the occupied area ratio of the obstruction is smaller than a preset obstruction area threshold, and the channel temperature is smaller than a preset temperature threshold, judging that the fire fighting channel is available; otherwise, judging that the fire fighting access is unavailable. The preset temperature threshold may be set according to an actual fire-fighting standard, and is not specifically limited herein.

In the embodiment of the application, when determining whether the fire fighting access is available, the temperature information is also considered, the safety performance of the available fire fighting access can be further provided, and the fire fighting personnel can conveniently make a disaster relief strategy.

In one possible implementation, a fire fighting system of an embodiment of the present application includes: a smoke sensing device 103 and a temperature collection device 104. The environment information of the fire fighting channel comprises smoke information, temperature information, flame information and occupation information; the server 102 is further configured to: acquiring smoke information of the designated monitoring area acquired by the smoke sensing equipment 103 and temperature information of the designated monitoring area acquired by the temperature sensing equipment 104;

The server 102 analyzes smoke information, temperature information, flame information and occupancy information of the fire fighting access to determine whether the fire fighting access is available. For example, the server 102 determines the ratio of the flame occupied area and the ratio of the blockage occupied area in the fire fighting tunnel according to the flame information and the occupancy information of the fire fighting tunnel, determines the tunnel temperature in the fire fighting tunnel according to the temperature information of the fire fighting tunnel, and determines the smoke concentration in the fire fighting tunnel according to the smoke information of the fire fighting tunnel. When the occupied area proportion of the flame is smaller than a preset flame area threshold, the occupied area proportion of the obstruction is smaller than a preset obstruction area threshold, the channel temperature is smaller than a preset temperature threshold, and the smoke concentration is smaller than a preset concentration threshold, the fire fighting channel is judged to be available; otherwise, judging that the fire fighting access is unavailable.

In the embodiment of the application, when determining whether the fire fighting access is available, the smoke information, the temperature information, the flame information and the occupation information are considered, so that the safety performance of the available fire fighting access can be further provided, and the fire fighting personnel can conveniently make a disaster relief strategy.

Besides the fire fighting access, the image acquisition equipment can also acquire image data of areas such as a personnel gathering area. Optionally, the number of the image capturing devices 101 is multiple, and each image capturing device 101 is respectively configured to capture image data of each designated monitoring area; the number of the fire fighting channels is multiple;

the server 102 is further configured to obtain a scene map and information of an area to be rescued; determining the target position of the area to be rescued in the scene map according to the information of the area to be rescued, wherein the scene map comprises the designated monitoring area; and determining the shortest path from the entrance to the target position in the available fire fighting channels by utilizing a preset shortest path algorithm according to the scene map and the target position.

The scene map is a map including each designated monitoring area. It is understood that the image capturing device is installed in a practical application scene, for example, the scene may be a large mall or an office building. The designated monitoring area is an area in the scene, and the image acquisition equipment acquires image data of the designated monitoring area.

The information of the area to be rescued is used for representing the area to be rescued, and the specific information of the area to be rescued can be position coordinates or marks of the area to be rescued. The area to be rescued may be entered by the firefighter or analyzed by the server 102. For example, the server 102 analyzes the image data, and takes an area with the largest number of trapped persons or the largest flame area as an area to be rescued. The server 102 determines the shortest path from each gateway to the area to be rescued by using a preset shortest path algorithm according to the scene map, the position of the area to be rescued in the scene map and the positions of the gateways. The preset shortest path algorithm may be any fire spreading algorithm in the related art, and is not specifically limited herein. In a possible embodiment, the area to be rescued is determined by a command center, the command center is in communication connection with the server 102, and the command center can perform data interaction with the server 102.

Generally, the number of the mobile terminal devices 105 is plural, but the number of the mobile terminal devices 105 is not limited in the embodiment of the present application. The mobile terminal device 105 communicates with the server 102 by using a wireless communication mode, and the mobile terminal device 105 has an information display function, can display a scene map, and can display a target position and a shortest path of an area to be rescued in the scene map.

Since the fire condition is changing, the currently planned safe escape route will change along with the spread of the fire, and in a possible implementation, the server 102 is further configured to determine the available time of each available fire fighting access through an associated fire spread algorithm, and determine the available time of the shortest path according to the available time of each available fire fighting access. For example, among the available fire corridors constituting the shortest path, the available time of the fire corridor whose available time is the shortest is taken as the available time of the shortest path. The server 102 may also send the available time of the shortest path to the mobile terminal device 105. Accordingly, when the mobile terminal device 105 displays the shortest path, it also displays the available time of the shortest path. Or the server 102 may send the available time of the shortest path to the information sign in the scene, so that the information sign displays the available time of the shortest path; or server 102 may send the shortest path available time to the speaker so that the speaker prompts for the shortest path available time in voice form. And the situation that the shortest path is unavailable after the personnel enter the shortest path is reduced.

The preset person detection algorithm may be any person detection algorithm in the related art, and is not specifically limited herein. Wherein the age group specifically comprises the elderly, children and young adults. The mobile terminal device 105 displays corresponding person information in each area of the scene map. Specifically, the mobile terminal device 105 may display one or more items in the person information, and the displayed items may be set according to actual situations, such as displaying only the total number of people, or displaying only the number of children and old people.

Taking the example of displaying all the person information as an example, the server 102 analyzes the image data of the designated monitoring area a, determines that the person information in the designated monitoring area a includes 2 children (females), 1 young and old year (females), and 1 young and old year (males), and the server 102 transmits the person information to the mobile terminal device 105. After receiving the terminal information, the mobile terminal device 105 marks and displays 2 children (females), 1 young and old (females), and 1 young and old (males) at the designated monitoring area a in the scene map.

In the embodiment of the application, the server obtains the personnel information of each designated monitoring area by analyzing the image data, and displays the corresponding personnel information at each designated monitoring area position in the scene map of the mobile terminal device, so that the firefighters can conveniently master the conditions of the rescuers, and the firefighters can conveniently make a disaster relief strategy in real time.

The area to be rescued may be determined by the server 102, and optionally, the personnel information includes the number, age group and gender of the personnel; the server 102 is further configured to analyze the staff information of each designated monitoring area, and determine the designated monitoring area where the staff information meets a preset rescue condition as the area to be rescued.

The preset rescue conditions can be set according to actual requirements, for example, the personnel information with the total number of people larger than the preset threshold number of people is set to meet the preset rescue conditions, or the personnel information including the old or the children is set to meet the preset rescue conditions, and the like.

In the embodiment of the application, the server is used for determining the area to be rescued, so that fire fighters can be assisted to make disaster relief strategies.

In view of the uncontrollable nature of the actual fire scenario, in many cases, there is a need for fire fighters to be randomly strained. Optionally, the mobile terminal device 105 is further configured to obtain a path calculation instruction for a specified location, which is input by a rescuer; transmitting the path calculation instruction to the server 102, wherein the path calculation instruction includes a terminal position of the mobile terminal and the designated position;
