[0002] In previous fire response procedures, fire commanders had to personally visit the fire scene to fulfill their command responsibilities, understand the current situation, and report back to the command center. Even then, direct access to on-site intelligence remained limited. For example, communicating with key personnel—property managers, site managers, and regional leaders—as well as identifying the source of the fire and the cause of the incident, took considerable time. This resulted in lost fire rescue time, increasing the difficulty of search and rescue operations at the scene and the resulting fire damage.

[0003] In view of this, it is necessary to provide a panoramic fire safety system to solve the above technical problems. [Utility Model Content]

[0004] In order to solve the above-mentioned problems of the conventional technology, the purpose of this application is to provide a panoramic fire safety system that can analyze the fire scene status in real time to improve the fire search and rescue rate and reduce property losses.

[0006] In some embodiments of the present application, the fire protection credit management module is further configured to pre-compare the values ​​of each group of environmental parameters to see if they are abnormal, and the abnormal groups of environmental parameters are marked by the fire protection credit management module.

[0007] In some embodiments of the present application, the main system further includes: an image playback module, which is connected to the event detection module and is configured to display the multiple real-time images; and a camera management module, which is connected to the image playback module, and the camera management module is configured to monitor the status of the multiple panoramic cameras, and the control signals for controlling the multiple panoramic cameras are transmitted to the multiple panoramic cameras via the image playback module.

[0008] In some embodiments of the present application, the main system further includes: an image playback module, which is connected to the event detection module and is configured to display the multiple real-time images and store the multiple real-time images; a scene management module, which is configured to have a scene map, and the multiple real-time images and the multiple sets of environmental parameters are marked on the scene map through the scene management module; wherein the marked scene map is presented through the image playback module.

[0011] In some embodiments of the present application, the event detection module is also connected to the abnormal notification module, and the abnormal notification module is also connected to the image storage module. When the abnormal situation occurs, the abnormal notification module transmits the notification information to the outside and then stores and transmits the abnormal situation image to the image storage module.

[0012] In some embodiments of the present application, the event detection module is connected to the multiple panoramic cameras via an audio and video transmission receiving module, and the event detection module is connected to the fire credit management module via a data transmission receiving module.

The main system pre-groups multiple environmental parameters sensed by multiple sensors through a fire credit management module, and uses an event detection module to identify whether abnormal conditions occur in different areas of the fire scene corresponding to the multiple sets of environmental parameters and real-time images. Therefore, the fire risks in different areas of the same fire scene can be recorded and perceived differently, so that the present application can simultaneously achieve the technical effects of reducing the computational burden of the event detection module and improving the efficiency of identifying the cause of the fire.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, rather than all the embodiments. In addition, it should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present application and are not intended to limit the present application.

[0030] Please refer to the drawings, wherein like reference numerals represent like elements.

[0031] Reference Figure 1 , Figure 1 Schematic diagram of a panoramic fire safety system according to an embodiment of the present application. The present application provides a panoramic fire safety system for assisting monitors in analyzing a fire scene. The system comprises: a plurality of panoramic cameras 30 configured to record a plurality of real-time images of the fire scene; a plurality of sensors 40 configured to sense a plurality of environmental parameters of the fire scene; a main system 20 connected to the plurality of panoramic cameras 30, the main system 20 comprising: a fire credit management module 21 connected to the plurality of sensors, the fire credit management module 21 configured to classify the plurality of environmental parameters into a plurality of groups of environmental parameters based on their types; an event detection module 22 connected to the fire credit management module 21, the event detection module 22 storing an abnormality condition and receiving a plurality of real-time images and a plurality of groups of environmental parameters. When the plurality of real-time images and the plurality of groups of environmental parameters meet the abnormality condition, the main system 20 identifies an abnormality in the fire scene; and an authentication module 10 connected to the main system 20 and configured as an interface between the main system 20 and an external unit A. After the authentication module 10 identifies the external unit A, it assigns the external unit A access rights to the abnormality data stored in the main system 20.

[0032] The authentication module 10 may be connected to more than one external unit A, and the authentication scheme implemented requires data verification between at least the authentication module 10 and at least two external units A in order to identify the authority to access abnormality data in the main system 20. For example, a first external unit A1 authorizes a set of authentication keys to be received by the authentication module 10, and a second external unit A2 is the external unit that desires to access abnormality data in the main system 20. When the second set of authentication keys transmitted by the second external unit A2 to the main system 20 meets the key conditions of the first set of authentication keys, the event detection module 22 transmits the set of environmental parameters and real-time image data that meet the key conditions to the second external unit A2. Alternatively, the first external unit A1 authorizes a set of authentication keys to be received by the authentication module 10, the second external unit A2 authorizes another set of authentication keys to be received by the authentication module 10, and the third external unit A3 is an external unit that desires to access data on abnormal conditions in the main system 20. When the access request transmitted by the third external unit A3 to the main system 20 meets the key conditions of the first set of authentication keys and the second set of authentication keys, the event detection module 22 transmits the set of environmental parameters and real-time screen data that meet the key conditions to the second external unit A2, so as to achieve dual authentication and access the set of environmental parameters and real-time screen data.

[0033] The fire protection credit management module 21 groups multiple environmental parameters based on their sensing location, sensing type, or a combination of these. For example, if the fire safety area analyzed by the panoramic fire safety system is the interior and exterior of a building, one set of environmental parameters might record temperature data on the third floor, another set might record humidity data on the fourth floor, or yet another set might record airflow intensity at the external vents between ducts. The data types of environmental data are not limited to humidity, temperature, or airflow intensity, and are not further described here. The fire protection credit management module 21 pre-groups the sensor data. If the event detection module 22 does not identify an abnormal condition, it combines the received multiple sets of sensor data with multiple live images and displays them through the image playback module 23. Alternatively, since each set of environmental parameters corresponds to a different location, the set of environmental parameters identified by the event detection module 22 as a location without abnormal conditions is combined with the corresponding live images and displayed through the image playback module 23.

[0034] In one embodiment provided by the present application, the fire protection credit management module 21 is further configured to pre-compare the values ​​of each group of environmental parameters to see if they are abnormal. Abnormal group environmental parameters are marked by the fire protection credit management module 21. When the event detection module 22 receives the group environmental parameters marked as abnormal, the event detection module 22 performs special processing on the abnormal group environmental parameters to ensure the operational stability of the main system 20. For example: it is checked again whether there are environmental parameters in the group environmental parameters that cause abnormal parameters, and it is determined whether the environmental parameters that cause abnormal parameters belong to the sorted abnormal conditions or are exceptions to the sorted abnormal conditions. At the same time, the event detection module 22 continues to compare the same group of environmental parameters based on the exceptions of the sorted abnormal conditions, and then defines a parameter for tracking the exception abnormal conditions to ensure system stability. Therefore, the abnormal conditions stored in the event detection module 22 can be generated based on the internal comparison of group environmental parameters at different time points and different groups of environmental parameters.

[0035] Continuing, refer to Figure 2 In one embodiment provided herein, the main system 20 further includes: an image playback module 23, connected to the event detection module 22 and configured to display multiple real-time images; and a camera management module 24, connected to the image playback module 23. The camera management module 24 is configured to monitor the status of multiple panoramic cameras 30, and control signals for the multiple panoramic cameras 30 are output by the camera management module 24 and transmitted to the multiple panoramic cameras 30 via the image playback module 23. The camera management module 24 is also configured to set access permissions and image output permissions for different panoramic cameras 30.

[0036] Reference Figure 3 In one embodiment provided herein, the main system 20 further includes: an image playback module 23, which is connected to the event detection module 22 and configured to display and store multiple real-time images; and a scene management module 25, which is configured to have a field map, on which multiple real-time images and multiple sets of environmental parameters are marked by the scene management module 25; wherein the marked field map is presented by the image playback module 23. The scene management module 25 is further configured to add, delete, and modify the layout of the field and environmental parameters displayed on the image playback module 23 for viewing by authorized users.

[0037] Reference Figure 4 In one embodiment of the present application, the event detection module 22 is further connected to an abnormality notification module 26. When an abnormality occurs, the abnormality notification module 26 transmits notification information. For example, when the event detection module 22 senses an abnormality, the abnormality notification module 26 transmits the identified abnormality data and the predicted abnormality location and type to an external unit A.

[0038] The main system 20 further includes an image storage module 27 connected to the event detection module 22. When an abnormality occurs, the image storage module 27 stores an abnormality image transmitted from the event detection module 22 for subsequent review by the external unit A.

[0039] The event detection module 22 is further connected to an abnormality notification module 26, which is further connected to an image storage module 27. When an abnormality occurs, the abnormality notification module 26 transmits a notification message and then transmits an abnormality image to the image storage module 27. In this embodiment, the abnormality image data designated as requiring notification by the abnormality notification module 26 is given a higher priority. Its data retention time, image clarity, and the number of combined environmental parameters are all superior to data directly stored in the image storage module 27 via the event detection module 22.

[0040] Reference Figure 5 In one embodiment provided in the present application, the event detection module 22 is connected to multiple panoramic cameras 30 through an audio and video transmission receiving module 28, thereby reducing the probability of accidental errors in receiving multiple real-time images, thereby improving the module scalability of the panoramic camera 30.

[0041] In one embodiment provided in the present application, the plurality of sensors 40 are further connected to the main system 20 through a fire credit system 50 configured to distinguish the status of the plurality of sensors 40 to ensure data consistency and data security between the additional sensors 40 and the main system 20 of the present application.

[0042] Reference Figure 6 In one embodiment provided herein, main system 20 further includes a notification system R1 connected to a notification system R2 external to main system 20. Event detection module 22 identifies abnormal conditions based on notification signals from notification systems R1 and R2. When an abnormal condition occurs, event detection module 22 transmits a notification message to the outside of main system 20 via notification system R1. For example, if notification system R2 is located inside a building, event detection module 22 uses notification system R1 to notify personnel within the building of the abnormal condition and their current safe haven location.

[0043] Reference Figure 7 In one embodiment provided in the present application, the event detection module 22 is connected to the fire credit management module 21 through a data transmission and receiving module 29, thereby reducing the probability of accidental errors in environmental parameters and improving module scalability.

[0044] Please refer to Figure 8 , Figure 8This is a flow chart of a panoramic fire safety system control method according to an embodiment of the present application. The panoramic fire safety system control method provided by the present application includes:

[0045] S1: Use multiple panoramic cameras to record multiple real-time images of the fire scene.

[0046] By using multiple panoramic cameras to record multiple real-time images of the fire scene, when a fire occurs, even if one of the panoramic cameras is burned or obscured by thick smoke, this application can still provide different display images to help fire commanders and the fire command center compare the current on-site conditions from multiple perspectives. In addition, it is also possible to analyze the spread of the fire by obtaining real-time images of different spaces within the same monitoring field. For example, a fire occurs in a building, where panoramic cameras are installed in the corridor space, fire fighting space, escape entrances and exits, and indoor or outdoor spaces of each building. Alternatively, a fire occurs inside a public transportation station, such as a metro station, train station, or bus terminal, and panoramic cameras are installed at the entrances and exits or in the night waiting area or women's waiting area.

[0047] S2: Use multiple sensors to sense multiple environmental parameters of the fire scene.

[0048] The sensor may be of different types, such as an indoor carbon dioxide concentration sensor, an oxygen sensor, a moisture sensor, a water level sensor of a water storage system, and the like.

[0049] S3: Use the main system to connect multiple panoramic cameras. The main system includes a fire credit management module and an event detection module.

[0050] S4: Using the fire protection credit management module, the multiple environmental parameters are divided into multiple groups of environmental parameters according to the types of the multiple environmental parameters.

[0051] S5: Use the event detection module to receive multiple real-time images and multiple sets of environmental parameters. When the multiple real-time images and multiple sets of environmental parameters meet abnormal conditions, the main system recognizes that an abnormal situation has occurred in the fire scene.

[0052] By combining the aforementioned fire protection credit management module 21 and event detection module 22, when a fire or fire safety incident occurs and the event detection module 22 receives a set of environmental parameters marked as abnormal, the event detection module 22 allocates computing resources to the abnormal set of environmental parameters to ensure the operational stability of the main system 20. Furthermore, by distributing environmental parameter analysis through the fire protection credit management module 21 and the event detection module 22, even if some environmental parameters and real-time images cannot be received due to equipment damage during a fire, the panoramic fire safety system control method provided in this application can still ensure that the fire protection credit management module 21 compares received sensor data at different time points to predict the current status of different combustion locations, providing the most appropriate fire status assessment and buying more time for fire rescue.

[0053] S6: After the external unit is identified using the authentication module 10, the external unit is assigned the authority to access the abnormal situation data in the main system.

[0054] By identifying at least one external unit A through the authentication module 10, or exchanging authentication information and authorization permissions of multiple external units, the panoramic fire safety system control method provided in this application can enable the external unit A to be authenticated and obtain abnormal situation data in a timely manner through the authentication module 10 when a fire occurs, thereby improving the rescue efficiency of collaboration between different external units.

[0055] In another embodiment provided by the present application, the fire protection credit management module 21 is further configured to pre-compare the values ​​of each group of environmental parameters to see if they are abnormal, and the abnormal group environmental parameters are marked by the fire protection credit management module 21.

[0056] Please refer to Figure 9 , Figure 9 It is a flowchart of a panoramic fire safety system control method according to an embodiment of the present application.

[0057] S21: Using the image playback module to display multiple real-time images.

[0058] S22: Using the camera management module to monitor the status of the plurality of panoramic cameras, and transmitting control signals for controlling the plurality of panoramic cameras to the plurality of panoramic cameras via the image playback module.

[0059] In this way, when the image playback module 23 displays an abnormal situation, the binding and adjustment of the camera can be managed through the camera management module 24 without adding other signal sharing. Moreover, the path of the transmission signal can also be simplified to be simultaneously transmitted back to the event detection module 22 through the image management module 23. Therefore, the present application can provide a simpler panoramic fire safety system control method.

[0060] Please refer to Figure 10 , Figure 10This is a flow chart of a panoramic fire safety system control method according to an embodiment of the present application, which includes:

[0061] S31: Using the image playback module to display multiple real-time images.

[0062] S32: Using the scene management module to store the scene map.

[0063] S33: Use the scene management module to mark multiple real-time images and multiple sets of environmental parameters on the scene map.

[0064] S34: Using the image playback module to present the marked scene map.

[0065] In this way, the scene management module 25 can cooperate with the image playback module 23 to complete the binding of the scene map with the existing real-time image and environmental parameters.

[0066] In one embodiment of the present application, the panoramic fire safety system control method further includes using the image storage module 27 to store abnormal situation images transmitted from the event detection module 22. This reduces the need for the event detection module 22 to occupy excessive storage resources, and when subsequent evidence review is needed, the image storage module 27 can be used to review the abnormal situation data and analyze the cause of the incident.

[0067] In another embodiment provided herein, the panoramic fire safety system control method further includes: when an abnormal situation occurs, using the abnormality notification module 26 to transmit a notification message to the outside of the main system 20, and then transmitting the abnormal situation image to the image storage module 27 via the abnormality notification module 26. In this way, the priority of the abnormal situation image after the notification can be increased after being marked by the abnormality notification module 26, so that the present application can further improve the efficiency and data security of abnormal situation data retrieval and ensure the retention of abnormal situation evidence.

[0068] The present application has at least the following beneficial effects: The present application provides a panoramic fire safety system and a panoramic fire safety system control method. By installing multiple panoramic cameras and multiple sensors in a fire scene, the main system pre-groups multiple environmental parameters sensed by multiple sensors through the fire credit management module, and uses the event detection module to identify whether abnormal conditions have occurred in different areas of the fire scene corresponding to the multiple sets of environmental parameters and the real-time images. Therefore, the fire risks in different areas of the same fire scene can be recorded and perceived differently, so that the present application can simultaneously achieve the technical effects of improving the operational distribution of the event detection module and improving the efficiency of identifying the cause of the fire. In addition, the fire credit management module is used to pre-judge the differences between each set of environmental parameters at different time points when classifying multiple sets of environmental parameters, thereby pre-judging whether each set of environmental parameters is abnormal, and marking the abnormal environmental parameter groups, so as to improve the prediction accuracy of the occurrence of abnormal events and gain more rescue time for fire events. Furthermore, the present application sets up an authentication module between the external unit and the main system to identify the external unit that wants to access the data stored in the event detection module. When an emergency disaster occurs, the panoramic fire safety system provided by the present application can instantly identify the external unit and assign access permissions.

[0069] It should be noted that the combination of the various elements in the present application preferably forms the above-mentioned multiple embodiments, but this should not be interpreted as a limitation to the present application, that is, the various elements in the present application can also have more combinations and are not limited to the above-mentioned multiple embodiments.

[0070] Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the technical solutions and core concepts of the present application. Those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents, and such modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
