[0002] With the increase in human development and management activities in forest areas, the risk of forest fires caused by human activities in forest areas has increased. Due to the complex terrain and undulating terrain in forest areas, some forest fire trucks cannot directly drive to the fire area. Therefore, firefighters are required to carry water pipes, water pumps and other fire-fighting equipment on foot to the fire area. However, since the firefighters themselves cannot obtain the fire information and location information of the fire area, they can only carry a certain amount of fire-fighting equipment to the fire area based on experience. On the one hand, if they are not familiar with the location of the fire area, the time cost of finding the destination is relatively high. On the other hand, due to insufficient fire-fighting equipment, multiple round-trip manual transportation is often required. Summary of the invention

[0053] Among them, firefighters can use the Beidou positioning device 40 they wear to record various routes of different sizes in the forest area and mark multiple locations in the forest area.

[0054] In one possible example, the server 10 in the smart forest fire fighting system 1 first obtains the first position information and fire image data of the target fire area in the target forest area from the fire information collection device, and then the server 10 determines the combustible information and the fire information according to the fire image data and the first position information, and the fire information includes the fire area and the fire height. The server 10 then determines the target water flow required for fire extinguishing according to the fire information, and the fire information includes the fire area, the fire height and the combustible information. The server 10 then determines the target water source for fire extinguishing according to the first position information. Further, the server 10 obtains the water source information of the target water source, and obtains The server 10 includes the water pump information and the target water pipe information, the water source information includes the second position information of the target water source, the target water pipe information includes the target length, target diameter, elbow information and valve information of a single target water pipe, and the water pump information includes the water pump flow rate.

Finally, the server 10 sends the total length, the number of water pumps and the target working power to the monitoring and management system.

[0055] See also Figure 2 , Figure 2 It is a flow chart of a fire scene information processing method based on a smart wearable device provided in an embodiment of the present application, which is applied to a server in a smart forest fire fighting system. The smart forest fire fighting system includes the server, a monitoring and command system, a Beidou positioning device used by a user, and a fire information collection device. The server is respectively connected to the monitoring and command system and the fire information collection device in communication, and the monitoring and command system is connected to the Beidou positioning device in communication. The method includes:

[0056] Step S201, obtaining first position information and fire image data of a target fire area in a target forest area from the fire information collection device.

[0057] Among them, the fire image data can be an image of the fire area taken by a fire information collection device; there can be multiple fire information collection devices, and multiple fire information collection devices simultaneously photograph the fire area from multiple angles, and each fire information collection device sends the multiple images it takes to the server.

[0058] The fire information collection device may include a positioning component and a processing unit. The positioning component may be used to locate the position of the fire information collection device itself. The processing unit calculates the positions of multiple collection points in the target fire area, i.e., first position information, based on its own position and the shooting distance from the target fire area, and sends the first position information to the server. Alternatively, the fire information collection device may send the shooting distance and its own position information to the server, and the server calculates the first position information of the target fire area based on the shooting distance and the position of the fire information collection device. Figure 3 , Figure 3 is a schematic diagram of a target fire area provided in an embodiment of the present application. The target fire area is an area surrounded by the positions of multiple collection points of multiple fire information collection devices. The multiple collection points include collection point 1, collection point 2, collection point 3, collection point 4, collection point 5, collection point 6, collection point 7, collection point 8, collection point 9, collection point 10, collection point 11, collection point 12, collection point 13 and collection point 14.

[0059] Step S202: Determine combustible material information and fire intensity information according to the fire image data and the first position information, wherein the fire intensity information includes fire area and fire height.

[0060] The combustible material information includes the type of combustible material and the target combustible material load per unit area, such as weeds, fallen leaves, lichens, mosses, tree roots, trees, etc.

[0061] The server generates a regular or irregular fire area map according to the multiple locations included in the first location information, and estimates the area of ​​the fire area map to obtain the fire area.

[0062] Step S203, determining the target water flow required for fire extinguishing according to the fire intensity information and the combustible material information.

[0063] Among them, the water flow rate required for fire extinguishing is positively correlated with the combustible load. The more combustible load, the greater the water flow rate required for fire extinguishing, and the less combustible load, the smaller the water flow rate required for fire extinguishing.

[0064] Step S204: determining a target water source for fire extinguishing according to the first position information.

[0065] Among them, the locations of multiple water sources in the target forest area can be recorded in advance on the spot, and the target water source is the water source determined to be closest to the target fire area.

[0066] Step S205, obtaining water source information of the target water source, as well as water pump information and target water pipe information.

[0067] The water source information includes the second location information and available water volume of the target water source, the target water pipe information includes the target length, target diameter, elbow information and valve information of a single target water pipe, and the water pump information includes the water pump flow rate.

[0068] The elbow information includes the number and type of elbows of the target water pipe, and the valve information includes the number and type of valves of the target water pipe.

[0069] Step S206: Determine the number of water pumps required for fire extinguishing according to the target water flow and the water pump information.

[0070] Among them, target water flow / water pump water flow=number of water pumps.

[0071] Step S207: determining the total length of the target water pipe required to be laid according to the first position information and the second position information.

[0072] Step S208: determining the target working power required for each water pump according to the first position information, the second position information, the target water pipe information and the water pump flow rate.

[0073] Among them, when the height difference between the target fire area and the target water source is greater, the water pump maintains the water flow rate of the pump.

[0074] Step S209: sending the total length, the number of water pumps and the target operating power to the monitoring management system.

[0075] It can be seen that in the embodiment of the present application, the server in the smart forest fire fighting system first obtains the first position information and fire image data of the target fire area in the target forest area from the fire information collection device, and then determines the combustible information and fire information based on the fire image data and the first position information, and the fire information includes the fire area and the fire height, and then determines the target water flow required for fire extinguishing based on the fire information, and the fire information includes the fire area, the fire height and the combustible information, and then determines the target water source for fire extinguishing based on the first position information, and further obtains the target water source. The water source information of the target water source, as well as the water pump information and the target water pipe information, the water source information includes the second position information of the target water source, the target water pipe information includes the target length, target diameter, elbow information and valve information of a single target water pipe, the water pump information includes the water pump flow, and further, according to the target water flow and water pump information, the number of water pumps required for fire fighting is determined, and then, according to the first position information, the second position information, the target water pipe information and the water pump flow, the target working power required for each water pump is determined, and finally, the total length, the number of water pumps and the target working power are sent to the monitoring and management system. The server obtains and analyzes the first position information, fire information, water pump information, target water pipe information and water source information of the target fire area to obtain the total length of the water pipe required for fire fighting, the number of water pumps and the target working power of each water pump, so that firefighters can know the equipment information required for fire fighting in a timely and accurate manner, which is conducive to improving the intelligence of the server in processing fire scene information.

[0076] In one possible example, in terms of determining the target water flow rate required for fire extinguishing based on the fire intensity information and the combustible material information, the above method may include the following steps: determining the spread area of ​​the target fire area before the user reaches the target fire area; determining the target total amount of combustibles based on the combustible material information, the fire intensity area and the spread area; determining a fire extinguishing water flow rate set, the fire extinguishing water flow rate set including the correspondence between the total amount of combustibles and the water flow rate; determining the target water flow rate required for fire extinguishing based on the total amount of combustibles and the fire extinguishing water flow rate set.

[0077] Among them, from the discovery of the target fire area to the user arriving at the target fire area to extinguish the fire, the fire often spreads continuously, and thus the burned area also continues to increase. The spread area of ​​the fire during this period can be predicted first, and the sum of the spread area and the fire area is the burned area when the user arrives at the fire extinguishing point.

[0078] Among them, the target total amount of combustible materials = target combustible material load * burned area.

[0079] Among them, there is a positive proportional relationship between the total amount of combustible materials and the water flow rate. The more the total amount of combustible materials, the greater the water flow rate required for fire extinguishing, and the smaller the total amount of combustible materials, the smaller the water flow rate required for fire extinguishing.

[0080] The server includes a memory, and the memory is used to store a fire extinguishing water flow set.

[0081] It can be seen that in this example, the server can determine the spread area before the user reaches the target fire area, and then determine the total amount of combustibles, query the fire extinguishing water flow set with the total amount of combustibles, and obtain the target water flow required for fire extinguishing.

[0082] In one possible example, the method for determining the spread area of ​​the target fire area before the user reaches the target fire area may include the following steps: acquiring meteorological data and terrain data of the target fire area; predicting the first time required for the user to reach the fire area; and determining the spread area of ​​the target fire area within the first time based on the meteorological data, the combustible material information, the terrain data and the first time.

[0083] Among them, the first position information of the target fire area can be used to query the meteorological database to obtain corresponding meteorological data such as temperature, humidity, wind speed, wind direction, precipitation, etc.; the first position information can be used to query the geographic information database to obtain terrain data within a certain range including the target fire area, and the terrain data includes ground height, slope, direction, terrain undulation, etc.

[0084] Among them, the fire spread model can be determined, and the meteorological data, terrain data, and combustible information can be input into the fire spread model at the first time. The fire spread model predicts the spread area of ​​the target fire area in the first time.

[0085] It can be seen that in this example, the electronic device determines the corresponding target rowing training environment according to the user's first rowing training level, and assists the user in conducting targeted training in rowing posture, rowing explosive power, and rowing endurance, which is conducive to improving user experience and improving the intelligence of the electronic device in processing rowing data.

[0086] In one possible example, in terms of determining the target operating power required for each water pump based on the first position information, the second position information, the target water pipe information and the water pump flow, the above method may include the following steps: determining the terrain height difference between the target fire area and the target water source based on the first position information and the second position information; determining a target head equivalent increase; determining a target head based on the terrain height difference and the head equivalent increase; determining the target operating power of each water pump based on the target head, the water pump flow, water density, gravitational acceleration and pump efficiency.

[0087] The greater the height difference between the target fire area and the target water source, the greater the working power required for the water pump to overcome gravity and deliver water at the water pump flow rate, and the smaller the height difference between the target fire area and the target water source, the smaller the working power required for the water pump to deliver water at the water pump flow rate. The water pump flow rate may be the maximum water flow rate of the water pump.

[0088] Among them, the elbow resistance, valve resistance and pipe friction resistance in the water pipe will also affect the water flow rate of the water pump. Therefore, in order to overcome these resistances and maintain water delivery at the water pump flow rate, greater working power is required.

[0089] Among them, the estimation formula of water pump power is: Among them, ρ is water density, g is gravity acceleration, n is pump efficiency, Q is pump flow, H1 is terrain height difference, H2 is target head equivalent increase, and P is target work efficiency. The influence of elbow resistance, valve resistance, and water pipe friction resistance can be equivalently converted into the quantity characterized by gravity influence, that is, equivalent head increase.

[0090] It can be seen that in this example, the server takes into account factors such as gravity, elbow resistance, valve resistance, and water pipe friction resistance to estimate the precise target operating efficiency of the water pump, which is conducive to improving the accuracy of the server in determining the target operating power of the water pump to deliver water at the pump flow rate.

[0091] In one possible example, in terms of determining the target head equivalent increase, the method may include the following steps: determining the friction coefficient between the target water pipe and water; determining a first head equivalent increase value according to the water pump flow, the total length, the target diameter, the gravitational acceleration and the friction coefficient; determining a first local resistance coefficient of the elbow of the target water pipe, and determining the number of elbows to be used; determining a second head equivalent increase value of a single elbow according to the first local resistance coefficient, the gravitational acceleration and the water pump flow, and determining a third head equivalent increase value according to the number of elbows and the second head equivalent increase value; determining a second local resistance coefficient of a valve of the target water pipe, and determining the number of valves to be used; determining a fourth head equivalent increase value of a single valve according to the second local resistance coefficient, the gravitational acceleration and the water pump flow, and determining a fifth head equivalent increase value according to the number of valves and the fourth head equivalent increase value; determining a target head equivalent increase value according to the first head equivalent increase value, the third head equivalent increase value and the fifth head equivalent increase value.

[0092] Among them, the first head equivalent increase is the equivalent conversion of the influence of the friction resistance of the water pipe into the quantity represented by the influence of gravity. The formula for the first head equivalent increase is as follows: h1 represents the equivalent increase in the first head, f1 is the friction coefficient, L represents the total length of the target water pipe, D represents the pipe diameter, v represents the fluid velocity, v=Q / A, and A represents the cross-sectional area of ​​the target water pipe. The friction coefficient is recorded in advance and is related to the pipe material and roughness of the target water pipe.

[0093] Among them, the equivalent increase of the second lift is the equivalent conversion of the influence of the elbow resistance into the quantity represented by the influence of gravity. The formula for the equivalent increase of the second lift is as follows: h2 represents the equivalent increase of the second head, f2 is the first local resistance coefficient, and the first local resistance coefficient can be obtained by prior experiments. The equivalent increase of the third head = the equivalent increase of the second head * the number of valves.

[0094] Among them, the fourth head equivalent increase value is the equivalent conversion of the influence of valve resistance into the quantity represented by gravity influence. The formula for the fourth head equivalent increase value is as follows: h2 represents the fourth head equivalent increase value, f2 is the second local resistance coefficient, and the second local resistance coefficient can be obtained by prior experiment. The fifth head equivalent increase value = the fourth head equivalent increase value * the number of elbows.

[0095] Among them, the target head equivalent added value = the first head equivalent added value + the third head equivalent added value + the fifth head equivalent added value.

[0096] It can be seen that in this example, the server can respectively calculate the first head equivalent increase value corresponding to the water pipe resistance, the second head equivalent increase value corresponding to the valve resistance, and the fourth elbow resistance increase value corresponding to the elbow resistance, and further calculate the target head equivalent increase value, which is conducive to improving the accuracy of the server in determining the target working power of the water pump to deliver water at the pump flow rate.

[0097] In one possible example, in terms of determining the first local resistance coefficient of the elbow of the target water pipe, the above method may include the following steps: determining the target elbow identifier of the elbow of the target water pipe; determining a first resistance coefficient set, the first resistance coefficient set including the correspondence between the elbow identifier and the local resistance coefficient; querying the first resistance coefficient set with the target elbow identifier to obtain the first local resistance coefficient.

[0098] Among them, different types of elbows have different local resistance coefficients. The first resistance coefficient set can be queried by using the target elbow identifier of the elbow used in the target water pipe to obtain the first local resistance coefficient.

[0099] Optionally, different types of valves have different corresponding resistance coefficients, and the target valve identifier of the valve of the target water pipe can be determined; a second resistance coefficient set is determined, and the second resistance coefficient set includes the correspondence between the valve identifier and the local resistance coefficient; the second resistance coefficient set is queried with the target valve identifier to obtain the second local resistance coefficient.

[0100] The memory of the server may store the first set of resistance coefficients and the second set of resistance coefficients in advance.

[0101] It can be seen that in this example, the server can directly query the first drag coefficient set and the second drag coefficient set to determine the first local drag coefficient and the second local drag coefficient, which is conducive to improving the efficiency of the server in determining the first local drag coefficient and the second local drag coefficient.

[0102] In one possible example, in determining the total length of the target water pipe required to be laid based on the first position information and the second position information, the method may include the following steps: generating a water pipe laying trajectory based on the first position information and the second position information; and determining the total length of the target water pipe required to be laid based on the water pipe laying trajectory.

[0103] Among them, based on the first position information of the target fire area and the second position information of the target water source, a water pipe laying trajectory in which people can lay water pipes on foot can be generated, and the total length of the target water pipes to be laid is greater than or equal to the actual length of the water pipe laying trajectory.

[0104] It can be seen that in this example, the server can first generate a water pipe laying trajectory between the target fire area and the target water source, and then determine the total length of the required water pipes based on the water pipe laying trajectory, which is conducive to improving the accuracy of determining the total length of the water pipe laying.

[0105] In a possible example, after sending the number of water pumps and the target operating power to the monitoring and management system, the method may further include the following steps: generating a target fire situation map based on the first location information and the fire information; and sending the target fire situation map to the monitoring and management system.
