[0022] In order to more clearly understand the purpose, technical solutions and advantages of the present application, the present application is described and explained below in conjunction with the drawings and examples. However, it should be understood by those skilled in the art that the present application can be implemented without these details. It is obvious to those skilled in the art that various changes can be made to the embodiments disclosed in the present application, and the general principles defined in the present application can be applied to other embodiments and application scenarios without deviating from the principles and scope of the present application. Therefore, the present application is not limited to the embodiments shown, but conforms to the broadest scope claimed in the present application.

[0023] The embodiments of the present application are further described in detail below in conjunction with the drawings of the specification.

[0024] The present application is directed to fire supervision in a park such as a cell, an office building, etc. The park includes outdoor, indoor and corridor. The indoor includes a plurality of owners, each of which corresponds to an indoor space, wherein the owner includes a buyer and a tenant. The present application is provided with a temperature sensing device in the space corresponding to each owner, which can be one of a temperature sensor or a temperature and humidity sensor, and the present application preferably uses a temperature sensor as the temperature sensing device. A smoke device is provided in the corridor of the indoor, and a shooting device is provided in the outdoor of the park. The fire supervision of the entire park is carried out through the shooting device, the smoke device, the temperature sensing device provided in the entire park, and the water meter originally provided in each owner's corresponding space. It is not necessary to provide various detection devices at the same time in the place to be supervised, such as providing a shooting device, a smoke device and a temperature sensing device at the same time in A place to be supervised. Instead, only one of the devices can be used, and the fire supervision is carried out by setting one of the devices for different places. By means of the water meter device originally provided, the number of detection devices can be reduced, thereby reducing the cost of fire supervision.

[0025] The fire monitoring method and the centralized control method of the fire in the present application are applied in an integrated security and fire fighting platform, Figure 1 is a schematic diagram of an integrated security and fire fighting platform provided by the embodiments of the present application. As Figure 1 shown, the integrated security and fire fighting platform includes an information detection layer, a cloud platform layer and an application layer. The information detection layer is deployed with the temperature sensing device, the smoke device, the shooting device, the wind information detection device and the fire fighting pipe network device, etc. The cloud platform layer is connected with the information detection layer, receives the information detected by the information detection layer, processes the information to obtain the fire monitoring result. The application layer is connected with the cloud platform layer, receives the fire monitoring result obtained by the cloud platform layer, and displays or provides corresponding guidance for subsequent processing based on the fire monitoring result. Figure 2 is a block diagram of a fire monitoring method provided by the embodiments of the present application. As Figure 2 shown, a fire monitoring method includes the following steps: Step S100, obtain a work signal, obtain fire-fighting water information of the park based on the work signal, and determine whether the fire-fighting water is being used based on the fire-fighting water information.

[0026] The embodiment of the application is described in the cloud platform layer. The above-mentioned work signal refers to a signal that needs to be supervised. The work signal can be sent by the staff when there is a need for fire supervision to the cloud platform layer, so that the cloud platform layer obtains the work signal; or the cloud platform layer is provided with a supervision time that needs to be supervised, and the current time is checked to see if it is the supervision time, if it is the supervision time, the cloud platform layer automatically generates a work signal to make the cloud platform layer obtain the work signal. The way of obtaining the work signal is not limited further here.

[0027] Because the fire in the park will definitely make the fire-fighting water be used, but the use of fire-fighting water does not necessarily mean that the fire has occurred in the park, it may be water stealing or some other irregular operation. But the fire-fighting water is not used, and the fire does not occur. That is, after the cloud platform layer obtains the work signal, it immediately obtains the fire-fighting water information of the fire-fighting water flow state in the fire-fighting pipe network by reading the flow value deployed in the fire-fighting pipe network. The fire-fighting water information includes the fire-fighting water flow value and the water pressure value. If at least one of the fire-fighting water flow value and the water pressure value in the fire-fighting water information is a non-zero value, the fire-fighting water is characterized as being used. If the fire-fighting water flow value and the water pressure value in the fire-fighting water information are both zero, the fire-fighting water is characterized as not being used.

[0028] When the fire-fighting water information is characterized as not being used, it indicates that the fire-fighting water in the park is not used irregularly, at this time, the fire-fighting water information of the park is continuously obtained.

[0029] Step S200, if yes, listen to the temperature sensing device to obtain the temperature sensing information corresponding to each homeowner, and obtain the smoke information group detected by the smoke device, determine whether a fire occurs in the space corresponding to the homeowner based on the smoke information group and the temperature sensing information, and generate a homeowner alarm signal when a fire occurs.

[0030] When the fire-fighting water information is characterized as being used, it indicates that the fire-fighting water in the park may be used irregularly, or it may be normally used because of fire. At this time, in order to further determine whether a fire occurs, the cloud platform layer immediately starts the temperature sensing device and the smoke device, so that the temperature sensing device and the smoke sensing device are in a working state. The number of temperature sensing devices can be determined according to the space corresponding to the homeowner, so that there is no overlap between the detection ranges of all temperature sensing devices and the sum of the detection ranges of all temperature sensing devices is less than the space corresponding to the homeowner.

[0031] Each temperature sensing device corresponds to a temperature sensing installation position. The temperature sensing device sends the temperature sensing installation position and the detected temperature sensing temperature to the cloud platform layer. After the cloud platform layer obtains the respective temperature sensing installation position and temperature sensing temperature sent by each temperature sensing device, the temperature sensing installation position and the temperature sensing temperature corresponding to the same temperature sensing device form a temperature sensing array, and then all temperature sensing arrays corresponding to the same householder and the space plan corresponding to the householder are sent to the preset temperature sensing drawing model corresponding to the householder, and the temperature of the space corresponding to the householder is obtained through the processing of the preset temperature sensing drawing model. The temperature graph is the temperature sensing information corresponding to the householder. The cloud platform layer stores the space plan corresponding to each householder, and the preset temperature sensing drawing model is a model trained offline in advance. The above smoke information group refers to the combination of smoke information detected by each smoke device at the same time.

[0032] After obtaining the temperature sensing information corresponding to each householder and the smoke information group, whether a fire occurs in the space corresponding to the householder can be judged based on the smoke information group and the temperature sensing information respectively. The smoke information group includes the smoke information detected by each smoke device. For the smoke devices arranged in the corridor, the sum of the detection distances between two adjacent smoke devices is less than the installation distance of the two smoke devices. Each smoke information includes a smoke value and a smoke position of the smoke device. Figure 3 is a method block diagram provided by the embodiment of the present application for judging whether a fire occurs in the space corresponding to the householder based on the smoke information group and the temperature sensing information. As shown in Figure 3 judging whether a fire occurs in the space corresponding to the householder based on the smoke information group and the temperature sensing information includes the following steps: Step S201, judging the target householder based on the fire-fighting water information, and determining the target smoke outlet position corresponding to the target householder.

[0033] Step S202, obtaining the wind direction and wind speed in the corridor, and obtaining the target smoke information located on the left and right sides of the target smoke outlet position from the smoke information group, and determining the outlet smoke value of the target smoke outlet position based on the wind direction, the wind speed and the target smoke information.

[0034] Step S203, judging whether the outlet smoke value is not less than the preset fire smoke value and the temperature sensing value falls within the fire warning temperature range, if yes, a fire occurs in the space corresponding to the householder.

[0035] Step S204, otherwise, no fire occurs in the space corresponding to the householder.

[0036] Specifically, each fire-fighting water information also corresponds to a water use position. The target space located near the water use position can be obtained by comparing the water use position and the position corresponding to each space, and the householder corresponding to the target space is determined as the target householder.

[0037] Then each target householder is substituted into the park distribution map respectively to obtain the target smoke outlet position corresponding to each target householder. The target smoke outlet position represents the position at which the smoke in the space corresponding to the target householder can spread from the indoor space to the corridor. The target smoke outlet position specifically refers to the position of the door and window in the space corresponding to the target householder.

[0038] After the target smoke outlet position is determined, the wind direction and wind speed in the corridor can be obtained through the deployed wind information detection device. The target smoke position of the smoke device located on the left and right sides of the target smoke outlet position is obtained by comparing the target smoke outlet position with all smoke positions. Finally, the target smoke value corresponding to the target smoke position is the target smoke value located on the left and right sides of the target smoke outlet position. The target smoke information includes the target smoke value and the target smoke position. That is, it is determined which target smoke outlet positions the smoke in each indoor space corresponding to the target householder can spread from the indoor space to the corridor, and where the smoke device located on the left and right sides of the target smoke outlet position is located, and what the detected smoke value is.

[0039] Then, the wind direction, wind speed, and target smoke information are substituted into the preset smoke diffusion model to obtain the corresponding relationship between the smoke value and the position located between the two target smoke positions. Then, the target smoke outlet position is substituted into the corresponding relationship to obtain the outlet smoke value of the target smoke outlet position. Finally, the outlet smoke value and the preset fire smoke value are compared in size, and the target householder's corresponding temperature sensing information is compared with the preset fire warning temperature range in size to determine whether a fire occurs in the space corresponding to the target householder. The fire warning temperature range refers to the temperature required for a fire and the corresponding range size. The fire warning temperature range can be determined according to historical fire information.

[0040] That is, when the outlet smoke value is not less than the preset fire smoke value, and the target temperature sensing information falls within the preset fire warning temperature range, a fire occurs. Otherwise, no fire occurs. In this way, by means of the existing smoke device, the smoke value at the position where the smoke is most easily and quickly detected when a fire occurs in the indoor space is obtained. Then, the smoke value is compared with the preset fire smoke value, and the temperature sensing information is compared with the preset fire warning temperature range, so that the indoor fire can be determined more quickly and accurately, and the rapidity and accuracy of determining whether a fire occurs in the indoor space are improved.

[0041] When it is determined that a fire occurs in the space corresponding to the householder, the cloud platform layer immediately generates a householder alarm signal to inform the relevant staff which space corresponding to the householder has a fire, so that the relevant staff can timely understand where the fire occurs.

[0042] Preferably, generating the owner alarm signal when the fire occurs comprises the following steps: In step S205, it is determined whether the owner alarm signal is received within the preset historical time period. If yes, the alarm number of the received owner alarm signal is determined.

[0043] In step S206, the alarm level corresponding to the alarm number is determined, and the user alarm signal of the corresponding level is generated based on the alarm level.

[0044] Specifically, the user alarm signal includes a general user alarm signal, a fire abnormal user alarm signal, and a suspected fire user alarm signal. The preset historical time period can be a preset historical five minutes, and the alarm level includes a no alarm number alarm level, a less than five alarm number alarm level, and a not less than five alarm number alarm level. When no alarm corresponding to the target owner is received within the preset historical five minutes, a general user alarm signal is generated when a fire occurs. When the alarm number of the alarm corresponding to the target owner is less than five within the preset historical five minutes, a fire abnormal user alarm signal is generated when a fire occurs. When the alarm number of the alarm corresponding to the target owner is not less than five within the preset historical five minutes, a suspected fire user alarm signal is generated when a fire occurs. In this way, by refining the owner alarm signal, the false alarm problem can be filtered out. Similarly, when generating the corridor alarm signal and the outdoor alarm signal, this method can be used, and details are not repeated.

[0045] In step S300, based on the working signal, the smoke device is started to obtain the basic smoke information set. It is determined whether the basic smoke information set falls within the fire warning smoke range. If yes, the target corridor falling within the fire warning smoke range is obtained, and the target shooting information detected by the target shooting device corresponding to the target corridor is obtained. It is determined whether a fire occurs in the target corridor based on the target shooting information, and a corridor alarm signal is generated when a fire occurs.

[0046] After the cloud platform layer obtains the working signal, the smoke device is also started, so that the smoke device is in a working state. Among them, one smoke device can be arranged at each end and in the middle of each corridor, and the number of smoke devices is preferably three, so that the sum of the detection distances between the two adjacent smoke devices is less than the installation distance of the two smoke devices.

[0047] The smoke device obtains the smoke information set in the same manner as the smoke information set detected by the smoke device in step S200, and thus will not be described again. After obtaining the smoke information set, it is preliminarily determined whether the corridor has the possibility of fire based on the obtained smoke information set, that is, whether the smoke information set falls within the fire warning smoke range. When the smoke information set does not fall within the fire warning smoke range, it indicates that the corridor does not have the possibility of fire. The determination of whether the smoke information set falls within the fire warning smoke range includes the following steps: Step S301, obtaining the wind direction and wind speed in the corridor, and substituting the two smoke values belonging to adjacent positions and the wind direction and wind speed corresponding to the smoke position into the preset interpolation model based on the smoke position to obtain the interpolation smoke values at several positions on the position line corresponding to the smoke position.

[0048] Step S302, the interpolation smoke value and the corresponding position value form a difference smoke information, and all smoke information and difference smoke information are substituted into the distribution diagram drawing software to obtain a smoke distribution diagram.

[0049] Step S303, obtaining the maximum smoke value in the smoke distribution diagram, and determining whether the maximum smoke value is less than the preset fire smoke value. If not, the smoke information set falls within the fire warning smoke range.

[0050] Step S304, if it is less than, the smoke information set does not fall within the fire warning smoke range.

[0051] The wind direction and wind speed in the corridor are obtained in the same manner as the wind direction and wind speed in the corridor in step S202, and thus will not be described again. By checking whether there are other smoke positions between the smoke positions corresponding to the two smoke devices, if not, then the two smoke devices are the two smoke devices belonging to adjacent positions. If there are, then the two smoke devices are not the two smoke devices belonging to adjacent positions. After obtaining the two smoke devices belonging to adjacent positions, the smoke values detected by the two smoke devices belonging to adjacent positions are the two smoke values belonging to adjacent positions. Then, by substituting the two smoke information belonging to adjacent positions and the wind direction and wind speed between the smoke positions in the two smoke information into the preset interpolation model, interpolation smoke values at several positions on the position line corresponding to the two smoke positions are obtained. The preset interpolation model is obtained offline and stored in the monitoring end.

[0052] The interpolated smoke values ​​and corresponding location values ​​are then combined to form interpolated smoke information. This smoke information and interpolated smoke information are then fed into the distribution mapping software associated with the cloud platform layer. This software then generates a smoke distribution map. This smoke distribution map represents the smoke distribution map for all corridor areas, meaning that the smoke values ​​at each location within the corridor can be determined from the smoke distribution map. Different colors in the smoke distribution map correspond to unique smoke values.

[0053] The smoke distribution map can be used to determine the smoke value range within the map. The maximum value within this range is then determined as the maximum smoke value within the map. The maximum smoke value is then compared to a preset fire smoke value. If the maximum smoke value is less than the preset fire smoke value, the smoke information group does not fall within the fire warning smoke range. If the maximum smoke value is not less than the preset fire smoke value, the smoke information group falls within the fire warning smoke range. This allows smoke values ​​to be obtained for all areas of the corridor using only a limited number of smoke devices. The smoke distribution map provides a comprehensive and intuitive assessment of the potential for fire in the corridor.

[0054] When the smoke information group does not fall into the fire warning smoke range, it indicates that there is no possibility of fire in the corridor. At this time, the cloud platform layer will not generate a corridor alarm signal and will continue to obtain the smoke information group to perform subsequent operations. When the smoke information group falls into the fire warning smoke information range, it indicates that there is a possibility of fire in the corridor. At this time, the cloud platform layer will determine all places with a value not less than the preset fire smoke value from the smoke distribution map, and thus determine the corridors corresponding to these places as target corridors. The cloud platform layer then starts the shooting devices that can acquire these target corridors. These shooting devices are the target shooting devices, thereby obtaining the target shooting information detected by the target shooting devices corresponding to the target corridors. Then, based on the target shooting information, it is determined whether a fire has occurred in the target corridor. Among them, judging whether a fire has occurred in the target corridor based on the target shooting information includes the following steps: Step S305: Acquire outdoor flame information corresponding to the target corridor from the target shooting information.

[0055] Step S306: If the outdoor flame information indicates no flame, there is no fire in the target corridor.

[0056] Step S307: If the outdoor fire information indicates that there is fire, a fire occurs in the target corridor.

[0057] By using image recognition and other technologies, the outdoor flame information corresponding to the target corridor can be obtained from the target shooting information. The outdoor flame information refers to whether there is a flame in the outdoor image in the shooting information, and the outdoor flame information can be one of the following: there is a flame outdoors or there is no flame outdoors.

[0058] When the outdoor flame information is no flame, it indicates that the smoke in the corridor is existing in the corridor itself, and at this time, the target corridor has a fire. When the outdoor flame information is flame, it indicates that the smoke in the corridor is diffused from the outside, and at this time, the target corridor has no fire. After all, the possibility of the fire occurring in the corridor and the outside at the same time is extremely low. In this way, the outdoor flame information is obtained by means of the existing shooting device outside, and then whether the outdoor flame information is flame is used to accurately and low-costly determine whether the fire occurs in the corridor, thereby improving the accuracy of determining whether the fire occurs in the corridor and reducing the cost of determining whether the fire occurs in the corridor.

[0059] When it is determined that the fire occurs in the target corridor, the cloud platform layer immediately generates a corridor alarm signal to inform the relevant staff which corridor has the fire, so that the relevant staff can timely know which corridor has the fire.

[0060] Preferably, generating the corridor alarm signal when the fire occurs comprises: obtaining a target smoke area not less than a preset fire smoke value in the smoke distribution map, and generating the corridor alarm signal based on the target smoke area. That is, after it is determined which corridor has the fire, it is further determined which position of the corridor has the fire, so that the relevant staff can preliminarily determine the cause of the fire in combination with the specific position, thereby providing the fire cause for the subsequent corresponding measures and accelerating the progress of solving the fire.

[0061] Step S400, based on the work signal, the shooting device is started to obtain basic shooting information, whether the fire occurs outside is judged based on the basic shooting information, and the outdoor alarm signal is generated when the fire occurs.

[0062] Among them, based on the work signal, the shooting device is started to obtain the shooting information, comprising the following steps: Step S401, the current time corresponding to the work signal is obtained, whether the current time falls into the fire alarm high-frequency period is judged, if yes, a real-time shooting instruction is generated to start the shooting device, and real-time shooting is performed to obtain the shooting information.

[0063] Step S402, if not, an intermittent shooting instruction is generated to start the shooting device, and shooting is performed every first preset time to obtain the shooting signal.

[0064] The cloud platform layer stores the high-frequency period of fire alarm. The current time can be obtained by checking the clock provided by the cloud platform layer, and then the current time is compared with the upper limit time and the lower limit time in the stored high-frequency period of fire alarm to determine whether the current time falls into the high-frequency period of fire. If the current time falls into the high-frequency period of fire, it indicates that this is a high-incidence period of outdoor fire. After receiving the work signal, the cloud platform layer generates a real-time shooting instruction to start the shooting device, so that the shooting device shoots in real time to obtain shooting information. If the current time does not fall into the high-frequency period of fire, it indicates that this is not a high-incidence period of outdoor fire. After receiving the work signal, the cloud platform layer generates an intermittent shooting instruction to start the shooting device, so that the shooting device shoots every first preset time to obtain shooting information. In this way, the shooting device can reduce energy consumption while monitoring outdoor fires.

[0065] After obtaining the shooting information, image analysis and other work are performed on the obtained shooting information to obtain each element contained in the shooting information, and the obtained each element is compared with the fire element to determine whether the fire element is contained in each element. If the fire element is contained, it indicates that an outdoor fire has occurred, and an outdoor alarm signal is generated when a fire occurs to enable relevant personnel to promptly understand where the fire has occurred. If the fire element is not contained, it indicates that no outdoor fire has occurred. At this time, the cloud platform layer does not generate an outdoor alarm signal, continues to obtain shooting information, and thus performs subsequent operations. In this way, different places are set with a certain device for fire supervision, and the number of detection devices can be reduced by using the water meter device that is originally provided, thereby reducing the cost of fire supervision. Subsequently, the information detected by the set device is combined, rather than using the information obtained by the device to determine the fire supervision work of the corresponding area, to further more accurately determine the fire supervision work at each position in the park.

[0066] Preferably, the alarm signal includes a homeowner alarm signal, a corridor alarm signal, and an outdoor alarm signal. After generating the alarm signal, the cloud platform layer continues to obtain corresponding information based on the alarm signal at a second preset time interval. The first preset time is greater than the second preset time. So that fire supervision work continues after the alarm signal occurs.

[0067] The application also provides a cluster supervision method for fire. The method determines whether a fire occurs in each park based on the above-mentioned fire supervision method. Figure 4 A block diagram of a cluster supervision method for fire provided by the application is shown in FIG. 1. Figure 4 The cluster supervision method for fire includes the following steps: Step S500, receiving the information sent by each park, judging whether the information is an alarm signal, if so, determining the park corresponding to the information as the fire park where the fire occurs.

[0068] Step S600, obtaining the fire park position corresponding to each fire park, and feeding back each fire park position to the display screen for display.

[0069] The embodiment is described in the central management end, which is deployed with a plurality of cloud platform layers described above. Each cloud platform layer corresponds to a park, and each cloud platform layer will send the generated signal to the central management end in real time. Among them, when the alarm signal is generated in the cloud platform layer corresponding to the park, the alarm signal will be sent to the central management end as information. When the cloud platform layer corresponding to the park does not generate an alarm signal, a blank information will be sent to the central management end. Therefore, the central management end can receive the message sent by each park corresponding to the deployed cloud platform layer.

[0070] Subsequently, the central management end determines whether it is an alarm signal by checking whether each received information is a blank information, and determines the information which is not a blank information as an alarm signal, and determines the park corresponding to the alarm signal as the fire park where the fire occurs. Then check the park position of the park corresponding to each cloud platform layer stored in the central management end, so as to determine the fire park position of each fire park. Finally, send each obtained fire park position to the display screen connected to the central management end, so as to display each fire park where the fire occurs and their positions through the display screen. It is convenient to realize the fire supervision of multiple parks more intuitively.

[0071] The park is provided with a shooting device outdoors, a smoke device in the indoor corridor of the park, and a temperature sensing device in the space corresponding to each homeowner in the park. Figure 5 is a connection diagram of a fire monitoring system provided by an embodiment of the present application. As shown in Figure 5 A fire monitoring system includes an acquisition module, an indoor supervision module, a corridor supervision module and an outdoor supervision module.

[0072] The acquisition module is configured to acquire a working signal, acquire fire-fighting water information of the park based on the working signal, and determine whether the fire-fighting water is being used based on the fire-fighting water information. If the fire-fighting water is being used, the temperature sensing device is monitored to acquire temperature sensing information corresponding to each house owner, and a group of smoke information detected by the smoke device is acquired. The indoor monitoring module is configured to determine whether a fire occurs in a space corresponding to the house owner based on the group of smoke information and the temperature sensing information, and generate a house owner alarm signal when the fire occurs. The corridor monitoring module is configured to start the smoke device to acquire the group of smoke information based on the working signal, determine whether the group of smoke information falls within a fire warning smoke range, acquire a target corridor falling within the fire warning smoke range and target shooting information detected by a target shooting device corresponding to the target corridor if the group of smoke information falls within the fire warning smoke range, determine whether a fire occurs in the target corridor based on the target shooting information, and generate a corridor alarm signal when the fire occurs. The outdoor monitoring module is configured to start the shooting device to acquire shooting information based on the working signal, determine whether a fire occurs outdoors based on the shooting information, and generate an outdoor alarm signal when the fire occurs.

[0073] The other functions performed by the acquisition module, the indoor monitoring module, the corridor monitoring module, and the outdoor monitoring module and the technical details of each function are the same as or similar to the corresponding features in the fire monitoring method described above, and thus will not be described again here.

The centralized control system for a fire determines whether a fire occurs in each park based on the fire monitoring method described above. As shown in FIG. 1, the centralized control system for a fire includes a processing module and a display module. Figure 6

[0075] The processing module is configured to receive information sent by each park, determine whether the information is an alarm signal, and determine a park corresponding to the information as a fire park if the information is the alarm signal. The display module is configured to acquire a fire park position corresponding to each fire park, and feed each fire park position to a display screen for display.

[0076] The other functions performed by the processing module and the display module and the technical details of each function are the same as or similar to the corresponding features in the centralized control method for a fire described above, and thus will not be described again here.
