[0060] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0061] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0062] The main solutions of the embodiments of this application are:

[0063] Since the current mainstream design method for outdoor fire protection pipeline layout is still manual drawing, the layout of outdoor fire protection pipeline network and accessories involves its fire protection coverage and national standards, and often needs to rely on personnel's professional skills and design experience for layout. However, without the assistance of standardized methods, it is difficult for designers to obtain a feasible layout plan in a short time. In addition, since upstream professions such as architecture may be adjusted during the design process, once an adjustment occurs, if the design process of the original layout plan is not standardized and reasonable, it may take a lot of manual modification time and rework, and may even completely overturn the original plan. Such existing outdoor fire protection pipeline layout methods often consume a lot of manpower costs.

[0064] The present application provides a solution, which, based on the road centerline within the design scope and intelligent design, not only accurately determines the layout of the fire-fighting pipeline, but also reduces the consumption of manpower costs and improves the efficiency of the outdoor fire-fighting pipeline layout design.

[0065] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an outdoor fire-fighting pipeline layout device based on the center line of the road, etc. The following takes the outdoor fire-fighting pipeline layout system based on the center line of the road as an example to illustrate this embodiment and the following embodiments.

[0066] Based on this, the embodiment of the present application provides a method for arranging outdoor fire protection pipelines based on the center line of the road. Figure 1 , Figure 1 This is a flow chart of the first embodiment of the outdoor fire protection pipeline layout method based on the road center line of the present application.

[0067] In this embodiment, the outdoor fire protection pipeline layout method based on the road centerline includes steps S10 to S40:

[0068] Step S10, obtaining the properties of each building.

[0069] It should be noted that house attributes include house fire resistance rating, house volume and house structure.

[0070] In addition, the step of obtaining the building properties of each building is to input or import parameters such as the building fire resistance level and building volume within the design range, and the system will automatically record and save these parameter properties.

[0071] Step S20, obtaining the design flow of outdoor fire hydrants in the buildings within the design range according to the building attributes of each building.

[0072] It should be noted that the design flow of outdoor fire hydrants in buildings is a key fire protection design parameter. It usually refers to the water flow that the fire protection system needs to provide in the event of a fire to ensure that the fire can be effectively controlled and extinguished. This parameter is usually related to parameters such as building materials and structures.

[0073] In addition, the process of obtaining the design flow of outdoor fire hydrants in buildings within the design range is the result of a series of complex and effective algorithms calculated by the system based on the properties of each building. Specifically, input or import parameters such as the fire resistance level and building volume of the building within the design range, and the system automatically outputs the outdoor fire design flow of the building within the design range.

[0074] For example, in order to help understand the implementation process of the method for obtaining the design flow rate of outdoor fire hydrants in buildings within the design range obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 2 , Figure 2 A brief flow chart of a method for obtaining the design flow of outdoor fire hydrants in buildings within the design range is provided.

[0075] It is understandable that this intelligent acquisition of the design flow of outdoor fire hydrants in buildings reduces the time cost of manual calculations.

[0076] Step S30, determining whether the outdoor fire protection pipe network within the design range is arranged in a ring shape or a branch shape according to the design flow of the outdoor fire hydrants of the buildings within the design range.

[0077] It should be noted that the fire pipe network refers to the pipeline layout of the entire fire water supply system, which includes trunk pipes, trunk pipes, branch pipes, etc., forming a network structure for transporting fire water. The design of the fire pipe network must take into account the reliability and flexibility of water supply, and is usually required to be arranged in a ring or branch shape to improve the safety and reliability of water supply.

[0078] In addition, the main pipe is the main pipe in the fire water supply system, usually with a larger diameter, responsible for transporting a large amount of fire water from the water source (such as the municipal water supply network, fire water tank, etc.) to the entire building or area. They are the skeleton of the entire fire pipe system, ensuring that sufficient water volume and water pressure can be provided when a fire occurs.

[0079] In addition, the trunk pipe is a pipe connecting the main pipe and the branch pipe. They are usually arranged vertically or horizontally to distribute water from the main pipe to various areas or floors. In multi-story or high-rise buildings, the trunk pipe may refer to those vertical pipes connecting different floors to provide continuous water flow to the upper and lower floors. The diameter of the trunk pipe is usually smaller than that of the main pipe.

[0080] In addition, branches are usually smaller pipes used to distribute water to more specific points of use, such as fire hydrants, sprinkler heads, water monitors and other fire-fighting facilities. The diameter of the branch pipe is usually smaller than the main pipe to meet the needs of water distribution and ensure that the water flow can reach the farthest fire-fighting facilities.

[0081] In addition, the outdoor fire-fighting pipe network is arranged in a ring shape and in a branch shape. These two arrangements are usually distinguished based on the shape of the pipe network. The ring pipe network is a layout form of the water distribution network. The pipes are connected vertically and horizontally to form a ring. The water supply capacity of the ring pipe network is safer and more reliable than that of the branch pipe network. When a certain section of the pipe network is under maintenance or fails, it can still ensure water supply to the fire scene. The branch pipe network is another layout form of the water distribution network. The trunk pipe and the branch pipe are clearly separated to form a tree branch. The branch pipe network is arranged in a tree branch shape. When the pipe network is overhauled or damaged, the water in front will be cut off. Therefore, the scope of use of the branch pipe network should be limited. The outdoor fire-fighting water supply network can be arranged in a branch pipe network in the early stage of construction or when the fire-fighting water consumption is not large, but the possibility of connecting to a ring pipe network in the future should be considered.

[0082] Step S40, based on the road centerline within the design range, determine the pipeline layout on the basis of the outdoor fire protection pipe network arranged in a ring or branch shape, and lay out the fire hydrants and valve wells to obtain the outdoor fire protection pipeline layout result.

[0083] It should be noted that the road centerline usually refers to the regulations on road layout and spacing in urban planning and architectural design to ensure that fire trucks can reach the fire scene smoothly. Specifically, the distance between road centerlines should not be greater than 160 meters. This is to ensure that fire trucks can quickly reach various parts of the building for fire fighting and rescue under any circumstances. This regulation aims to improve the efficiency of fire fighting and rescue, ensure the safe evacuation of personnel, and prevent the spread of fire. In practical applications, the concept of road centerline has important guiding significance for the planning and design of fire lanes.

[0084] In addition, fire protection pipes usually refer to pipe materials used in fire protection, connecting fire protection equipment and instruments, and transporting fire extinguishing water, gas or other media. Fire protection pipes have special requirements for thickness and material according to special needs. They are often sprayed with red paint to distinguish them, and are required to have pressure resistance, corrosion resistance, high temperature resistance and other properties.

[0085] In addition, fire hydrants are a key facility in the fire water supply system, mainly used to provide water for fire extinguishing operations. They are usually installed on walls or on the ground inside and outside buildings to facilitate firefighters to quickly connect water hoses and water guns in emergency situations. The fire hydrant system includes indoor fire hydrants and outdoor fire hydrants. Outdoor fire hydrants may also include fire pump connectors for fire trucks to replenish water. The design and layout of fire hydrants should meet the requirements of rapid response and covering sufficient protection area.

[0086] In addition, a valve well is an underground well chamber structure used to install valves, water meters or other water supply equipment. It provides an easily accessible and maintainable space for valves and other equipment. It is usually equipped with a well cover to protect the internal facilities. The role of the valve well in the fire protection system is to control water flow, regulate water pressure, isolate pipeline sections for maintenance or overhaul, and quickly cut off the water source in an emergency.

[0087] In addition, fire protection pipelines usually refer to specific pipes that transport fire-fighting water in fire protection systems. They can be underground or overhead pipes. Their design and construction must follow strict specifications and standards to ensure the safety and effectiveness of the system.

[0088] In addition, when the outdoor fire protection pipeline layout result is obtained, the system will automatically generate a fire protection pipeline layout diagram, and the appropriate output ratio can be selected according to the needs. For example, a 1:500 output ratio is required to fully display the fire protection pipeline layout diagram on A2 paper. It should be noted that the output ratio is the ratio of the paper area to the design range area.

[0089] For example, in order to help understand the implementation process of the method for laying out fire hydrants and valve wells in this embodiment in combination with the above-mentioned embodiment 1, please refer to Figure 3 , Figure 3 A simplified flow chart of a method for arranging fire hydrants and valve wells is provided, specifically: determining whether to connect the main pipes of each individual building from the main pipe; if the main pipes of each individual building are connected from the main pipe, determining the arrangement of a three-way valve well or a four-way valve well at the pipeline connection node; determining the arrangement of outdoor fire hydrants according to the design flow and spacing requirements of outdoor fire hydrants of the individual buildings; and determining the arrangement of the valve wells according to preset parameters based on the arrangement results and number of fire hydrants.

[0090] It should be noted that fire pipe connection nodes are an important part of the fire pipe system. They ensure that the pipes can be connected stably and safely. Three-way valve wells or four-way valve wells are also a type of valve wells. During design and construction, it is necessary to determine whether to use a three-way or four-way valve well based on specific engineering requirements and site conditions. For example, if a road's rainwater drainage system needs to collect water flows from different directions, a four-way valve well may be required to meet this requirement. Similarly, if only water flows need to be distributed or controlled in three directions, a three-way valve well may be sufficient.

[0091] In addition, after the main pipes and trunk pipes are arranged, fire hydrants will be automatically arranged according to the specifications of the protection range and spacing of fire hydrants.

[0092] In addition, the preset parameter is the relationship between the number of fire hydrants and the number of valve wells. For example, if the preset parameter is set to a ratio of 5 to 1 between the number of fire hydrants and the number of valve wells, the layout of the valve wells is determined according to the determined number of fire hydrants. If the number of fire hydrants is any number from 15 to 19, the number of valve wells is determined to be 3, and if the number of fire hydrants is any number from 20 to 24, the number of valve wells is determined to be 4. It can be understood that the location of the valve well is determined and arranged according to the location of the fire hydrants and the requirements of the specifications.

[0093] It can be understood that this intelligent determination of the layout of fire hydrants and valve wells not only improves the efficiency of obtaining layout results, but also further ensures fire safety.

[0094] For example, in order to help understand the implementation process of the method for laying out fire hydrants and valve wells in this embodiment in combination with the above-mentioned embodiment 1, please refer to Figure 4 , Figure 4 A brief flow diagram of a method for obtaining outdoor fire-fighting pipeline layout results is provided, specifically: according to the layout results of valve wells, the types, quantities and various parameters of valve wells are counted, and a valve well drawing is automatically generated; the properties and quantities of outdoor fire-fighting pipelines are automatically counted; the layout results and numbers of fire hydrants are automatically counted; and the outdoor fire-fighting pipeline layout result drawing is automatically generated according to the properties and quantities of outdoor fire-fighting pipelines, the layout results and numbers of fire hydrants and the valve well drawing.

[0095] It should be noted that the valve well drawing includes the layout, size, quantity table and depth of various valves. The outdoor fire protection pipeline layout drawing includes the layout results of each pipeline, the attribute parameters of various pipes, the layout results of fire hydrants and the layout results of valve wells.

[0096] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 5 , S30 may include steps S301 to S302:

[0097] Step S301, judging whether the maximum design flow rate among the design flows of the outdoor fire hydrants of the buildings within the design range exceeds a first flow rate threshold, and determining whether the outdoor fire protection pipe network within the design range is arranged in a ring shape or a branch shape.

[0098] It should be noted that the maximum design flow rate among the design flows of outdoor fire hydrants in buildings within the design range is calculated and counted by the system, thereby determining the maximum design flow rate. The system can make a comparison and judgment based on this maximum design flow rate and the first flow threshold, thereby determining the layout of the subsequent outdoor fire protection pipe network. It should be noted that the unit of the design flow rate of outdoor fire hydrants in buildings is liters per second, that is, the water flow rate per second.

[0099] In addition, the flow threshold is a controllable threshold, and the setting of the flow threshold can be set to a suitable threshold according to different geographical locations or environments. For example, the first flow threshold is set to 20L / s. If the maximum design flow rate of the design flow rate of the outdoor fire hydrants of the building within the design range is greater than 20L / s, then the outdoor fire-fighting pipe network within the design range is determined to be arranged in a ring shape, and the parameters of the ring pipe network are calculated and annotated, thereby determining the layout of the trunk pipe, and calculating and annotating the parameters of the trunk pipe; if the maximum design flow rate of the design flow rate of the outdoor fire hydrants of the building within the design range is not greater than 20L / s, then the outdoor fire-fighting pipe network within the design range is determined to be arranged in a branch shape, and the parameters of the branch pipe network are calculated and annotated.

[0100] It can be understood that calculating and marking the parameters of various pipes is the process of the system identifying, calculating and marking the diameter, length and other parameter information of each pipe. This parameter information provides a solid foundation for the pipeline layout steps.

[0101] Step S302, judging whether the design flow of the outdoor fire hydrant of the single building within the design range exceeds the second flow threshold, and determining whether the outdoor fire protection pipe network of the single building within the design range is arranged in a ring shape or a branch shape.

[0102] It should be noted that the step of judging whether the design flow of the outdoor fire hydrant of the single building within the design range exceeds the second flow threshold is that the system judges in turn whether the design flow of the outdoor fire hydrant of each single building exceeds the second flow threshold. For example, the second flow threshold is set to 21L / s, and the system will judge in turn whether the design flow of the outdoor fire hydrant of each single building exceeds 21L / s. If the design flow of the outdoor fire hydrant of a single building exceeds 21L / s, the outdoor fire-fighting pipe network of the single building is determined to be arranged in a ring shape, and the trunk pipe is determined to be connected from the main pipe, and the parameters of the trunk pipe are calculated and marked; if the design flow of the outdoor fire hydrant of another single building does not exceed 21L / s, the outdoor fire-fighting pipe network of the single building is determined to be arranged in a branch shape, and the branch pipe is determined to be connected from the main pipe, and the parameters of the branch pipe are calculated and marked.

[0103] For example, in order to help understand the implementation process of the method for determining the ring-shaped or branch-shaped arrangement of the outdoor fire protection pipe network within the design range in this embodiment in combination with the above-mentioned embodiment 2, please refer to Figure 6 , Figure 6 A specific flow chart of a method for determining the ring-shaped or branch-shaped arrangement of an outdoor fire protection pipe network within a design scope is provided.

[0104] This pipeline network layout determination based on intelligent judgment not only improves the accuracy of pipeline network layout and various parameter data, but also saves labor costs.

[0105] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the first and second embodiments can be referred to the above description, and will not be described in detail later. Figure 7 , step S40 also includes steps S401 to S404:

[0106] Step S401, identifying the road centerline within the design range.

[0107] It should be noted that the system recognition process is that the system automatically imports the attributes of the road center based on the information provided by the road professionals.

[0108] Step S402, obtaining parameter information of the main pipe, trunk pipe and branch pipe.

[0109] It should be noted that in the above steps, the system has recorded and saved the parameter information of the main pipe, trunk pipe and branch pipe. The system can obtain these parameter information by directly reading the stored parameter information or by obtaining the required parameter information after re-uploading.

[0110] Step S403, determining the distances between the road centerline within the design range and the main pipeline, trunk pipeline and branch pipeline respectively according to the road centerline within the design range.

[0111] It should be noted that the step of determining the distances between the center line of the road within the design range and the trunk pipe, trunk pipe and branch pipe respectively is to calculate and determine the distances between the center line of the road and the trunk pipe, trunk pipe and branch pipe.

[0112] Step S404, determining the pipeline layout based on the outdoor fire protection pipe network arranged in a ring or branch shape based on the distances between the road centerline and the main pipe, trunk pipe and branch pipe respectively.

[0113] It should be noted that the step of determining the pipeline layout is to reasonably plan the pipeline direction according to the building structure and usage function. Specifically, the pipeline layout is determined on the basis of the outdoor fire-fighting pipe network arranged in a ring or branch shape according to the distance between the center line of the road and the main pipe, trunk pipe and branch pipe, and casing is automatically added at intersections and crossing sections.

[0114] This embodiment improves the rationality of pipeline layout results by combining the road centerline with the pipeline layout method.

[0115] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the outdoor fire protection pipeline layout method based on the road center line of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0116] This application also provides an outdoor fire protection pipeline layout device based on the road centerline, please refer to Figure 8 The outdoor fire-fighting pipeline arrangement device based on the road centerline includes:
