[0063] The fire-fighting equipment operation adjustment module is used to adjust the operation status of the fire-fighting equipment inside the ancient building based on the real-time information.

[0064] The beneficial effects of the above embodiments are as follows: the fire prediction system for ancient buildings analyzes the meteorological monitoring data of the area where the ancient buildings are located, obtains the characteristic information of thunderstorm weather in the area, and predicts the attribute information of lightning strikes on the ancient buildings, and makes a comprehensive and accurate prediction of the potential location and time of lightning strikes on the ancient buildings; based on the attribute information of lightning strikes, the lightning charge distribution data of the ancient buildings during lightning strikes is obtained, so as to judge whether lightning charge accumulation events occur in the ancient buildings, identify the situation where the lightning protection equipment of the ancient buildings cannot effectively conduct the charges in time, and provide a reliable basis for predicting that the ancient buildings will break through the building structure and cause fires due to excessive accumulation of lightning charges; based on the location information of the fire events in the ancient buildings, the ancient buildings are visually identified to obtain the real-time information of the fire events, so as to adjust the working status of the fire-fighting equipment, timely extinguish the fire in the ancient buildings and prevent the fire from expanding, and comprehensively predict and investigate the lightning strikes and potential fire risks suffered by the ancient buildings, thereby improving the safety of the ancient buildings.

[0065] In another embodiment, the thunderstorm weather recognition module is used to analyze the meteorological monitoring data of the area where the ancient building is located to obtain thunderstorm weather characteristic information of the area where the ancient building is located, including:

[0066] Acquire satellite radar echo data of the area where the ancient building is located, perform time evolution analysis on the satellite radar echo data, and obtain severe convective weather change trend information of the area where the ancient building is located; based on the severe convective weather change trend information, obtain thunderstorm weather characteristic information of the area where the ancient building is located; wherein the thunderstorm weather characteristic information includes thunderstorm weather occurrence time information and thunderstorm weather coverage range information of the area where the ancient building is located;

[0067] The lightning strike event prediction module is used to predict the attribute information of the lightning strike event of the ancient building based on the thunderstorm weather characteristic information, including:

[0068] Based on the thunderstorm weather characteristic information and the architectural appearance information of the ancient building, the attribute information of the lightning strike event of the ancient building is predicted; wherein the architectural appearance information includes the structural outline and structural height information of the ancient building; the attribute information of the lightning strike event includes the location information of the part of the ancient building that was struck by lightning and the occurrence time information.

[0069] The beneficial effects of the above embodiments are that strong convective weather such as squall lines and supercells will produce high-frequency large-scale thunderstorms. If these strong convective weather occurs in the area where the ancient buildings are located, the probability of the ancient buildings being struck by lightning and causing fires will increase. For this reason, the accurate prediction of fires in ancient buildings due to lightning strikes needs to be based on the accurate prediction of the occurrence of strong convective weather in the area where the ancient buildings are located. The satellite radar echo data of the area where the ancient buildings are located is obtained, and the time evolution analysis of the corresponding artificial intelligence weather model is performed on the satellite radar echo data to obtain the strong convective weather change trend information in the area where the ancient buildings are located; wherein the strong convective weather change trend information may be but is not limited to the change trend of the diffusion range of strong convective weather over time. Then the strong convective weather change trend information is studied and analyzed to obtain the thunderstorm weather occurrence time information and thunderstorm weather coverage information in the area where the ancient building is located, so as to accurately predict the thunderstorm coverage and duration in the area where the ancient building is located, and provide basic data for the subsequent identification of the lightning strikes that the ancient building may suffer. In addition, the shape of the ancient building itself also has a certain influence on the lightning strike hit rate. For example, the lightning strike hit rate of the higher parts of the ancient building is higher than that of the lower parts, and the parts with sharp shapes are higher than those with smooth shapes. Therefore, based on the occurrence time information of thunderstorm weather and thunderstorm coverage information in the area where the ancient building is located and the architectural appearance information of the ancient building (such as the height of different parts of the ancient building and the appearance contour of different parts, etc.), the lightning strike situation of the ancient building is analyzed, and the attribute information of the lightning strike event of the ancient building is predicted, so as to make a comprehensive and accurate prediction of the location information and occurrence time information of the lightning-struck part of the ancient building, so as to provide a reliable basis for the subsequent more detailed prediction of the fire occurrence situation of the ancient building.

[0070] In another embodiment, the lightning charge distribution determination module is used to obtain lightning charge distribution data corresponding to the lightning strike event of the ancient building based on the attribute information of the lightning strike event, including:

[0071] Based on the location information of the ancient building struck by lightning and the time information of the occurrence of the lightning strike event contained in the attribute information of the lightning strike event, the lightning charge conduction data of the lightning protection device of the ancient building during the lightning strike event is obtained; the lightning charge conduction data is analyzed to obtain the lightning charge distribution data corresponding to the process of the lightning strike event of the ancient building; wherein the lightning charge distribution data includes the distribution position and distribution amount of the lightning charge on the ancient building;

[0072] The fire event prediction module is used to analyze the lightning charge distribution data to determine whether a lightning charge accumulation event occurs in the ancient building; when the lightning charge accumulation event occurs, the location information of the ancient building where a fire event may occur is predicted, including:

[0073] Analyze the lightning charge distribution data to identify whether the charge amount distributed at a certain position on the ancient building exceeds a preset charge amount threshold, and if so, determine that a lightning charge accumulation event has occurred in the ancient building; if not, determine that no lightning charge accumulation event has occurred in the ancient building;

[0074] When the lightning charge accumulation event occurs, based on the charge transmission trend at the location where the lightning charge accumulation event occurs in the ancient building, it is predicted whether a fire event is likely to occur at the location.

[0075] The beneficial effect of the above-mentioned embodiment is that in order to improve the lightning protection performance of ancient buildings, ancient buildings will be installed with lightning protection equipment such as lightning rods, so that after the ancient buildings are hit by thunderstorms, the lightning charges can be quickly conducted to the ground, avoiding the accumulation of a large amount of lightning charges in the local area of ​​the ancient buildings, so that the ancient buildings are not necessarily hit by thunderstorms. Fire. However, in actual work, due to factors such as the aging of the working performance of the lightning protection equipment itself, the lightning charges cannot be conducted to the ground in time, causing excessive accumulation of lightning charges in local locations inside the ancient building, which will increase the probability of the local location being struck by lightning and causing a fire. When the amount of charge distributed in the local location of the ancient building exceeds the preset charge threshold, it is judged that the ancient building has a lightning charge accumulation event, which is easy to induce the corresponding local location to be struck by lightning. Also, when the lightning charge accumulation event occurs, based on the charge transfer trend at the location where the lightning charge accumulation event occurs on the ancient building, it is predicted whether a fire event is likely to occur at that location. For example, based on the charge transfer residence time and charge transfer rate at the location where the lightning charge accumulation event occurs on the ancient building, it is determined whether the accumulated charge at the location where the lightning charge accumulation event occurs on the ancient building gradually increases to the maximum charge that the ancient building can bear. If so, it is determined that a fire event is likely to occur at that location, thereby globally identifying and locating all locations where fire events may occur on the ancient building.

[0076] In another embodiment, the fire situation recognition module is used to visually recognize the corresponding part of the ancient building based on the location information to determine the real-time information of the fire event, including:

[0077] Based on the location information of the ancient building where a fire may occur, thermal infrared photography is performed on the corresponding parts of the ancient building to obtain corresponding thermal infrared dynamic images; the thermal infrared dynamic images are identified to determine whether the fire event has occurred and the scope of the fire after it has occurred, which is used as the real-time information;

[0078] The fire-fighting equipment working adjustment module is used to adjust the working state of the fire-fighting equipment inside the ancient building based on the real-time information, including:

[0079] Based on the real-time information, the spraying direction and spraying water flow rate of the fire sprinkler equipment inside the ancient building are adjusted.

[0080] The beneficial effect of the above embodiment is that, based on the location information of the ancient building where the fire incident may occur, the corresponding part of the ancient building is photographed by directional thermal infrared, the thermal infrared dynamic image of the part is obtained, and the thermal infrared dynamic image is recognized to determine whether the fire incident has occurred and the scope of the fire incident after the occurrence, so as to accurately identify the fire situation of the ancient building. In addition, based on the real-time information, the spraying direction and spraying water flow of the fire sprinkler equipment inside the ancient building are adjusted to ensure that the fire can be extinguished quickly and accurately when the fire occurs in the ancient building, so as to prevent the fire from further spreading.

Then the strong convective weather change trend information is studied and analyzed to obtain the thunderstorm weather occurrence time information and thunderstorm weather coverage information in the area where the ancient building is located, so as to accurately predict the thunderstorm coverage and duration in the area where the ancient building is located, and provide basic data for the subsequent identification of the lightning strikes that the ancient building may suffer. In addition, the shape of the ancient building itself also has a certain influence on the lightning strike hit rate. For example, the lightning strike hit rate of the higher parts of the ancient building is higher than that of the lower parts, and the parts with sharp shapes are higher than those with smooth shapes. Therefore, based on the occurrence time information of thunderstorm weather and thunderstorm coverage information in the area where the ancient building is located and the architectural appearance information of the ancient building (such as the height of different parts of the ancient building and the appearance contour of different parts, etc.), the lightning strike situation of the ancient building is analyzed, and the attribute information of the lightning strike event of the ancient building is predicted, so as to make a comprehensive and accurate prediction of the location information and occurrence time information of the lightning-struck part of the ancient building, so as to provide a reliable basis for the subsequent more detailed prediction of the fire occurrence situation of the ancient building.

[0090] In another embodiment, based on the attribute information of the lightning strike event, the lightning charge distribution data corresponding to the lightning strike event of the ancient building is obtained; the lightning charge distribution data is analyzed to determine whether a lightning charge accumulation event occurs in the ancient building; when the lightning charge accumulation event occurs, the location information of the ancient building where a fire event may occur is predicted, including:

[0091] Based on the location information of the ancient building struck by lightning and the time information of the occurrence of the lightning strike event contained in the attribute information of the lightning strike event, the lightning charge conduction data of the lightning protection device of the ancient building during the lightning strike event is obtained; the lightning charge conduction data is analyzed to obtain the lightning charge distribution data corresponding to the process of the lightning strike event of the ancient building; wherein the lightning charge distribution data includes the distribution position and distribution amount of the lightning charge on the ancient building;

[0092] Analyze the lightning charge distribution data to identify whether the charge amount distributed at a certain position on the ancient building exceeds a preset charge amount threshold, and if so, determine that a lightning charge accumulation event has occurred in the ancient building; if not, determine that no lightning charge accumulation event has occurred in the ancient building;

[0093] When the lightning charge accumulation event occurs, based on the charge transmission trend at the location where the lightning charge accumulation event occurs in the ancient building, it is predicted whether a fire event is likely to occur at the location.

[0094] The beneficial effect of the above-mentioned embodiment is that in order to improve the lightning protection performance of ancient buildings, ancient buildings will be installed with lightning protection equipment such as lightning rods, so that after the ancient buildings are hit by thunderstorms, the lightning charges can be quickly conducted to the ground, avoiding the accumulation of a large amount of lightning charges in the local area of ​​the ancient buildings, so that the ancient buildings are not necessarily hit by thunderstorms. Fire. However, in actual work, due to factors such as the aging of the working performance of the lightning protection equipment itself, the lightning charges cannot be conducted to the ground in time, causing excessive accumulation of lightning charges in local locations inside the ancient building, which will increase the probability of the local location being struck by lightning and causing a fire. When the amount of charge distributed in the local location of the ancient building exceeds the preset charge threshold, it is judged that the ancient building has a lightning charge accumulation event, which is easy to induce the corresponding local location to be struck by lightning. Also, when the lightning charge accumulation event occurs, based on the charge transfer trend at the location where the lightning charge accumulation event occurs on the ancient building, it is predicted whether a fire event is likely to occur at that location. For example, based on the charge transfer residence time and charge transfer rate at the location where the lightning charge accumulation event occurs on the ancient building, it is determined whether the accumulated charge at the location where the lightning charge accumulation event occurs on the ancient building gradually increases to the maximum charge that the ancient building can bear. If so, it is determined that a fire event is likely to occur at that location, thereby globally identifying and locating all locations where fire events may occur on the ancient building.

[0095] In another embodiment, when the lightning charge accumulation event occurs, based on the charge transmission trend at the location where the lightning charge accumulation event occurs in the ancient building, predicting whether a fire event may occur at the location includes:

[0096] Step S1, assuming that after a lightning charge accumulation event occurs, the amount of charge flowing into the location where the lightning charge accumulation event occurs in the ancient building at time t is I in (t), the charge outflow at time t is I out (t), then the charge accumulation from the initial time t0 to time t is:

[0097]

[0098] In the above formula (1), Q(t) is the charge outflow at the location where the lightning charge accumulation event occurred in the ancient building. out (t), then Q(t0) is the charge accumulation from the initial time t0 to time t, and Q(t0) is the charge accumulation at the corresponding position at the initial time t0. This fully considers the charge inflow and outflow in all time periods, provides a complete history of charge accumulation, and can be updated according to real-time monitoring data to reflect the latest charge status in a timely manner. It has the advantages of comprehensiveness, accuracy, continuity and real-time performance.

[0099] Step S2, based on the calculation result of the above step S1, determine the charge accumulation rate at the location where the lightning charge accumulation event occurs in the ancient building,

[0100]

[0101] In the above formula (2), R(t) is the charge accumulation rate at the location where the lightning charge accumulation event occurred in the ancient building. This formula is used to calculate the first-order derivative of Q(t); by analyzing the positive and negative signs and magnitude of R(t), we can understand the trend of charge accumulation and predict future changes. At the same time, when the charge accumulation rate changes significantly, we can take quick measures, such as adjusting the lightning protection system or starting fire-fighting equipment.

[0102] Step S3, based on the calculation results of the above steps S1 and S2, predict whether a fire event may occur at the location where the lightning charge accumulation event occurs in the ancient building,

[0103]

[0104] In the above formula (3), f(t) is the judgment value of whether a fire event may occur at the location where the lightning charge accumulation event occurs in the ancient building; when f(t) is 1, it indicates that a fire event may occur at the location where the lightning charge accumulation event occurs in the ancient building; when f(t) is 0, it indicates that a fire event is unlikely to occur at the location where the lightning charge accumulation event occurs in the ancient building; Q s is the charge accumulation threshold. By using the two conditions of R(t) and Q(t), the possibility of false alarm is reduced. Q can also be adjusted according to the actual situation. s to suit different safety standards and risk preferences.

[0105] The beneficial effect of the above embodiment is that when a lightning charge accumulation event occurs, the accumulated charge at the lightning strike location does not continue to stay at the location, but will undergo corresponding conduction and reach the ground. It can be seen that there is an inflow and outflow of charge at the same time at the location, so it is difficult to predict whether a fire event may occur at the location. However, the prediction of whether a fire event may occur at the location must be accurate, otherwise it may cause excessive disposal or delayed disposal, which will have a certain degree of impact on the ancient building. According to the charge inflow and charge outflow at the location where the lightning charge accumulation event occurs in the target ancient building after the lightning charge accumulation event, an accurate prediction is made as to whether a fire event may occur at the location where the lightning charge accumulation event occurs in the ancient building, so as to avoid the occurrence of excessive disposal or delayed disposal due to inaccurate prediction.

[0106] In another embodiment, based on the location information, visual recognition is performed on the corresponding part of the ancient building to determine the real-time information of the fire event; based on the real-time information, the working state of the fire-fighting equipment inside the ancient building is adjusted, including:

[0107] Based on the location information of the ancient building where a fire may occur, thermal infrared photography is performed on the corresponding parts of the ancient building to obtain corresponding thermal infrared dynamic images; the thermal infrared dynamic images are identified to determine whether the fire event has occurred and the scope of the fire after it has occurred, which is used as the real-time information;

[0108] Based on the real-time information, the spraying direction and spraying water flow rate of the fire sprinkler equipment inside the ancient building are adjusted.

[0109] The beneficial effect of the above embodiment is that, based on the location information of the ancient building where the fire incident may occur, the corresponding part of the ancient building is photographed by directional thermal infrared, the thermal infrared dynamic image of the part is obtained, and the thermal infrared dynamic image is recognized to determine whether the fire incident has occurred and the scope of the fire incident after the occurrence, so as to accurately identify the fire situation of the ancient building. In addition, based on the real-time information, the spraying direction and spraying water flow of the fire sprinkler equipment inside the ancient building are adjusted to ensure that the fire can be extinguished quickly and accurately when the fire occurs in the ancient building, so as to prevent the fire from further spreading.

[0110] In general, the fire prediction system and method for ancient buildings analyzes the meteorological monitoring data of the area where the ancient buildings are located, obtains the characteristic information of thunderstorm weather in the area, and predicts the attribute information of lightning strikes on the ancient buildings, and makes a comprehensive and accurate prediction of the potential location and time of lightning strikes on the ancient buildings; based on the attribute information of lightning strikes, the lightning charge distribution data of the ancient buildings during the lightning strikes is obtained to determine whether lightning charge accumulation events have occurred in the ancient buildings, identify the situation where the lightning protection equipment of the ancient buildings cannot conduct the charges in a timely and effective manner, and provide a reliable basis for predicting that the ancient buildings will break through the building structure and cause fires due to excessive accumulation of lightning charges; based on the location information of the fire events in the ancient buildings, the ancient buildings are visually identified to obtain the real-time information of the fire events, so as to adjust the working status of the fire-fighting equipment, timely extinguish the fire in the ancient buildings and prevent the fire from expanding, and comprehensively predict and investigate the lightning strikes on the ancient buildings and potential fire risks, thereby improving the safety of the ancient buildings.
