Description

Technical Field

[0001] This invention relates to the field of thermal pipeline design technology, and in particular to a thermal pipeline planning method and related equipment. Background Technology

[0002] To meet the living needs of heating users, the design of the heating network directly impacts planning investment and economic efficiency during urban planning and construction. Heating methods are mainly divided into centralized heating and decentralized heating. Decentralized heating involves each heating user within the planned area using high-power equipment to provide heat energy, resulting in higher operating costs. Centralized heating, on the other hand, supplies heat energy from one or more heat sources to all heating users within the planned area through a heating network. This reduces operating costs and urban pollution, but it suffers from higher heat loss during transmission. Furthermore, centralized heating has poor flexibility in adjusting its terminals, making it difficult to meet the diverse needs of individual heating users. Therefore, centralized heating is not suitable for all heating users. Summary of the Invention

[0003] This application provides a method and related equipment for planning a heating network. By planning the route of the heating network according to the distribution of heating users, heat energy loss can be reduced and utilization rate can be improved.

[0004] In a first aspect, embodiments of this application provide a method for planning a thermal pipeline network, including:

[0005] The location of heat source points, distribution of first users, and load information of the planning area are obtained. The load information includes the maximum demand flow and total annual energy demand of each heating user in the first user distribution.

[0006] Based on the location of the heat source and the distribution of the first users, the main pipeline route and branch pipeline route are preset;

[0007] The main pipeline route connecting the heating users in the first user distribution from the preset main pipeline route and the branch pipeline route connecting the heating users in the first user distribution from the preset branch pipeline route are determined as the first pipeline route.

[0008] Based on the maximum demand flow corresponding to each heating user in the first user distribution, the first flow corresponding to each first pipeline route in the first pipeline network route is calculated, and the diameter of the first pipeline network is determined based on the flow range to which the first flow belongs.

[0009] Based on the first pipeline route, the first pipeline diameter, and the total annual energy demand of each heating user in the first user distribution, the first heating pipe diameter and the first heating flow rate corresponding to the first heating pipe diameter are calculated for each heating user in the first user distribution.

[0010] If the first heating flow rate corresponding to the first heating pipe diameter of each heating user in the first user distribution is greater than or equal to the preset threshold corresponding to the first heating pipe diameter, then it is determined that each heating user in the first user distribution adopts a centralized heating method, and the first pipeline route and the first pipeline diameter are determined as the target heating pipeline.

[0011] By planning the route of the heating network using the location of heat source points and the distribution of the first user in the planning area, and determining the heating users in the first user distribution who adopt centralized heating based on load information, the heating users who adopt centralized heating are connected to the target heating network, and the heating users in the first user distribution other than those who adopt centralized heating adopt decentralized heating, heat energy loss can be reduced and utilization rate can be improved.

[0012] In one possible design, if the first heating flow rate corresponding to the first heating user in the first user distribution is less than the preset threshold corresponding to the first heating pipe diameter, then the first heating user is deleted from the first user distribution to obtain a second user distribution; the first pipeline route connecting to the first heating user is deleted from the first pipeline route to obtain a second pipeline route; based on the maximum demand flow rate corresponding to each heating user in the second user distribution, the second flow rate corresponding to each second pipeline route in the second pipeline route is calculated, and the second pipeline diameter is determined based on the flow range to which the second flow rate belongs; based on the second pipeline route, the second pipeline diameter, and the total annual energy demand corresponding to each heating user in the second user distribution, the second heating pipe diameter and the second heating flow rate corresponding to the second heating pipe diameter are calculated; if the second heating flow rate corresponding to the second heating pipe diameter of each heating user in the second user distribution is greater than or equal to the preset threshold corresponding to the second heating pipe diameter, then it is determined that each heating user in the second user distribution adopts the centralized heating method, and the second pipeline route and the second pipeline diameter are determined as the target heating network. By determining the conditions, it is found that there are first heating users in the first user distribution who do not use centralized heating. The first heating users are then removed from the first user distribution to obtain the second user distribution. It is then determined whether each heating user in the second user distribution uses centralized heating. This process continues until the range of heating users using centralized heating no longer changes. This helps to determine the target heating network for the planning area, reduce the heat loss of centralized heating, and improve the utilization rate.

[0013] In another possible design, if the first heating flow rate corresponding to the first heating user in the first user distribution is less than the preset threshold corresponding to the first heating pipe diameter, then it is determined that the first heating user adopts a decentralized heating method. Determining that the first heating user adopts a decentralized heating method by judging the condition removes the first pipeline route connecting the first heating user from the first pipeline route of the centralized heating system. This helps to determine the decentralized heating range of the planned area, can meet the needs of heating users adopting a decentralized heating method, and improves heat energy utilization.

[0014] In another possible design, based on the maximum demand flow corresponding to each heating user in the first user distribution, the flow rate is calculated starting from the last pipe route in the first pipeline network route to obtain the first flow rate corresponding to each first pipe route in the first pipeline network route, thus determining the flow range to which the first flow rate of each first pipe route in the first pipeline network route belongs; based on the flow range to which the first flow rate of each first pipe route in the first pipeline network route belongs and the preset pipe diameter range corresponding to the flow range, the pipe diameter of the first pipeline network is determined. Determining the pipe diameter corresponding to each first pipe route in the first pipeline network route by using the flow range to which the first flow rate of each first pipe route in the first pipeline network route belongs and the preset pipe diameter range corresponding to the flow range helps to ensure that each first pipe route is within the optimal flow range.

[0015] In another possible design, based on the first pipeline route and the first pipeline diameter, the length of the first heating pipe corresponding to each heating user in the first user distribution and the first heating pipe diameter corresponding to the first heating pipe length are calculated. The first heating pipe length represents the pipe length between the first pipeline route accessed by each heating user in the first user distribution and the branch point closest to the first pipeline route. The total annual energy demand corresponding to each heating user in the first user distribution is divided by the length of the first heating pipe corresponding to each heating user in the first user distribution to obtain the first heating flow rate corresponding to the first heating pipe diameter. The first heating flow rate is used to determine whether each heating user in the first user distribution adopts the centralized heating method. By calculating the length of the first heating pipe, the first heating pipe diameter, and the first heating flow rate corresponding to the first heating pipe diameter for each heating user in the first user distribution, it is used to determine whether each heating user in the first user distribution is suitable for adopting the centralized heating method.

[0016] In another possible design, the location of the heat source is determined to be in a first direction within the planned area. Based on the first user distribution, the main pipeline route is preset on the road closest to the heat source and parallel to the first direction, and a first branch pipeline route is preset on the road closest to the heat source and perpendicular to the first direction. Based on the first direction, a branch pipeline route is preset on every other road parallel to the first branch pipeline route, and a branch pipeline route is preset on the last road parallel to the first branch pipeline route in the planned area. Based on the location of the heat source and the first user distribution within the planned area, the main pipeline route and branch pipeline routes are preset, allowing all heating users within the planned area to connect to the centralized heating network.

[0023] The processing module is further configured to determine that each heating user in the first user distribution adopts a centralized heating method if the first heating flow rate corresponding to the first heating pipe diameter of each heating user in the first user distribution is greater than or equal to the preset threshold corresponding to the first heating pipe diameter, and to determine the first pipeline route and the first pipeline diameter as the target heating pipeline.

[0024] In one possible design, the processing module is further configured to: delete the first heating user from the first user distribution and obtain a second user distribution if the first heating flow rate corresponding to the first heating user in the first user distribution is less than the preset threshold corresponding to the first heating pipe diameter; delete the first pipeline route connecting to the first heating user from the first pipeline route and obtain a second pipeline route; calculate the second flow rate corresponding to each second pipeline route in the second pipeline route based on the maximum demand flow rate corresponding to each heating user in the second user distribution, and determine the second pipeline diameter based on the flow range to which the second flow rate belongs; calculate the second heating pipe diameter and the second heating flow rate corresponding to each heating user in the second user distribution based on the second pipeline route, the second pipeline diameter, and the total annual energy demand corresponding to each heating user in the second user distribution; if the second heating flow rate corresponding to the second heating pipe diameter of each heating user in the second user distribution is greater than or equal to the preset threshold corresponding to the second heating pipe diameter, determine that each heating user in the second user distribution adopts the centralized heating method, and determine the second pipeline route and the second pipeline diameter as the target heating network.

[0025] In another possible design, the processing module is further configured to determine that the first heating user adopts a decentralized heating method if the first heating flow rate corresponding to the first heating user in the first user distribution is less than the preset threshold corresponding to the first heating pipe diameter.

[0026] In another possible design, the processing module is further configured to calculate, starting from the last first pipeline route in the first pipeline network route, the first flow rate corresponding to each first pipeline route in the first pipeline network route based on the maximum demand flow rate corresponding to each heating user in the first user distribution, and determine the flow range to which the first flow rate of each first pipeline route in the first pipeline network route belongs; and determine the pipe diameter of the first pipeline network based on the flow range to which the first flow rate of each first pipeline route in the first pipeline network route belongs and the preset pipe diameter range corresponding to the flow range.

[0027] In another possible design, the processing module is further configured to calculate, based on the first pipeline route and the first pipeline diameter, the length of the first heating pipe corresponding to each heating user in the first user distribution and the first heating pipe diameter corresponding to the length of the first heating pipe, wherein the length of the first heating pipe represents the length of the pipe between the first pipeline route accessed by each heating user in the first user distribution and the branch point closest to the first pipeline route; and to divide the total annual energy demand corresponding to each heating user in the first user distribution by the length of the first heating pipe corresponding to each heating user in the first user distribution to obtain the first heating flow rate corresponding to the first heating pipe diameter, wherein the first heating flow rate is used to determine whether each heating user in the first user distribution adopts the centralized heating method.

[0040] Figure 5 This is a schematic diagram of the structure of a server provided in an embodiment of this application. Detailed Implementation

[0041] The embodiments of this application are described below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, Figure 1 This is a schematic diagram of a thermal pipeline planning system provided in an embodiment of this application. The thermal pipeline planning system includes an information acquisition module 101 and a pipeline planning module 102. Detailed descriptions of each module are as follows.

[0043] The information acquisition module 101 is used to import the location of heat source points, the distribution of first users and load information of the planning area. The load information includes the maximum demand flow and the total annual energy demand of each heating user in the first user distribution.

[0044] Optionally, the information acquisition module 101 is also used to acquire the preset range of pipe diameters corresponding to different flow intervals and the preset thresholds corresponding to different heating pipe diameters. By calculating the heating flow rate corresponding to each pipeline route, the pipe diameter of each pipeline route is determined according to the preset range of pipe diameters corresponding to different flow intervals, so that each pipeline route is in the optimal flow range; the preset thresholds corresponding to different heating pipe diameters are used to determine whether each heating user in the first user distribution adopts the centralized heating method.

[0045] The pipeline planning module 102 is used to obtain the location of heat sources, the distribution of first users, and load information of the planning area from the information acquisition module 101; based on the location of heat sources and the distribution of first users, it presets the main pipeline routes and branch pipeline routes; it determines the main pipeline routes connecting to heating users in the first user distribution from the preset main pipeline routes and the branch pipeline routes connecting to heating users in the first user distribution from the preset branch pipeline routes as the first pipeline routes; based on the maximum demand flow corresponding to each heating user in the first user distribution, it calculates the first flow corresponding to each first pipeline route in the first pipeline routes, and based on the first... The first pipeline diameter is determined by the flow range to which the flow belongs. Based on the first pipeline route, the first pipeline diameter, and the total annual energy demand of each heating user in the first user distribution, the first heating pipeline diameter and the first heating flow rate corresponding to the first heating pipeline diameter are calculated for each heating user in the first user distribution. If the first heating flow rate corresponding to the first heating pipeline diameter of each heating user in the first user distribution is greater than or equal to the preset threshold corresponding to the first heating pipeline diameter, then it is determined that each heating user in the first user distribution adopts centralized heating, and the first pipeline route and the first pipeline diameter are determined as the target heating pipeline.

[0046] Heat sources are typically located at power plants or centralized heating points within the planned area, and their locations are usually marked directly on the planning maps by relevant departments. User distribution is determined by user type, which generally includes residential buildings, hospitals, hotels, shopping malls, industrial buildings, data centers, transportation hubs, schools, and other building types. For example, within the planned area, residential buildings, hospitals, hotels, shopping malls, and schools all have heating needs; industrial sites and hospitals all have steam load needs; hospitals, hotels, shopping malls, industrial sites, data centers, and transportation hubs all have cooling needs; and all of the above-mentioned sites have electricity load needs, while green spaces and riverside areas do not require electricity resources. Load information refers to the load variation characteristics of different types of buildings in different areas at different times of the year, and this information is generally obtained through databases or load simulation software.

[0047] It should be noted that the aforementioned heating network planning system can be an interactive system with users. This system can be a software system, a hardware system, or a combination of both; this application does not impose any specific limitations on it. It should also be noted that... Figure 1 This is merely an illustrative structural diagram of a heating network planning system; in practical applications, it can be modified according to specific circumstances. Figure 1 The thermal pipeline network planning system will be transformed accordingly.

[0048] like Figure 2 As shown, Figure 2 This is a flowchart illustrating a thermal pipeline planning method provided in an embodiment of this application. The method includes, but is not limited to, the following steps:

[0049] S201: Obtain the location of heat source points, distribution of first users, and load information for the planned area.

[0050] In one implementation, the system receives user-uploaded information on heat source locations, first user distribution, and load. Specifically, the heating network planning system provides a data upload interface, which includes a data upload button. Users can click the data upload button to upload pre-prepared information on heat source locations, first user distribution, and load to the heating network planning system.

[0051] In another implementation, the location of heat sources, the distribution of the first user, and load information are obtained from a database (including a local database or a database on another device). Further, information matching the requirements is searched to obtain the location of heat sources, the distribution of the first user, and load information for the planned area.

[0052] In this embodiment of the application, the location of the heat source is directly marked on the planning map by the relevant department. The first user distribution includes the distribution information of all heating users and related roads within the planning area. The load information includes the maximum demand flow and total annual energy demand corresponding to each heating user in the first user distribution.

[0053] S202: Based on the location of the heat source and the distribution of the first user, preset the main pipeline route and branch pipeline route.

[0054] Specifically, the location of the heat source is determined to be in the first direction of the planning area; based on the first user distribution, a main pipeline route is preset on the road closest to the heat source and parallel to the first direction, and a first branch pipeline route is preset on the road closest to the heat source and perpendicular to the first direction; based on the first direction, a branch pipeline route is preset on every other road parallel to the first branch pipeline route, and a branch pipeline route is preset on the last road parallel to the first branch pipeline route in the planning area.

[0055] In this embodiment of the application, if the heat source is located on the east or west side of the planning area, a main pipeline route is preset on the road closest to the heat source and running east-west, and a first branch pipeline route is preset on the road closest to the heat source and running north-south. Then, along the east-west direction, a branch pipeline route is preset on every other north-south road, and a branch pipeline route is preset on the last north-south road in the planning area.

[0056] Optionally, if the heat source is located on the south or north side of the planned area, a main pipeline route is pre-set on the road closest to the heat source and running north-south, and the first branch pipeline route is pre-set on the road closest to the heat source and running east-west. Then, along the north-south direction, a branch pipeline route is pre-set on every other east-west road, and a branch pipeline route is pre-set on the last east-west road in the planned area.

[0057] S203: The main pipeline route connecting to the heating users in the first user distribution and the branch pipeline route connecting to the heating users in the first user distribution, which are preset main pipeline routes, are determined as the first pipeline network route.

[0058] Specifically, it is determined whether each main pipeline route in the preset main pipeline route connects to the heating users in the first user distribution, and whether each branch pipeline route in the preset branch pipeline route connects to the heating users in the first user distribution. The main pipeline routes in the preset main pipeline route that connect to the heating users in the first user distribution and the branch pipeline routes in the preset branch pipeline routes that connect to the heating users in the first user distribution are determined as the first pipeline network routes.

[0059] In this embodiment of the application, if the preset main pipeline route and / or branch pipeline route connect to the heating users in the first user distribution, then the preset main pipeline route and / or branch pipeline route are determined to exist; otherwise, the preset main pipeline route and / or branch pipeline route do not exist. The first pipeline route of the planning area can be determined according to the above method.

[0060] S204: Based on the load information, calculate the first flow rate corresponding to each first pipeline route in the first pipeline network route, and determine the diameter of the first pipeline network according to the flow range to which the first flow rate belongs.

[0061] Specifically, the load information includes the maximum demand flow corresponding to each heating user in the first user distribution. Based on the maximum demand flow corresponding to each heating user in the first user distribution, the first flow corresponding to each first pipeline route in the first pipeline network is calculated starting from the last first pipeline route in the first pipeline network route. The flow range to which the first flow of each first pipeline route in the first pipeline network route belongs is determined. Based on the flow range to which the first flow of each first pipeline route in the first pipeline network route belongs and the preset range of pipe diameter corresponding to the flow range, the pipe diameter of the first pipeline network is determined.

[0062] like Figure 3 As shown, Figure 3 This is a schematic diagram illustrating an example of planning the diameter of a heating network according to an embodiment of this application. Each time the pipe branches, the transmitted flow also splits, and the flow transmitted by pipe 2 satisfies:

[0063] X2 = X4 + X5

[0064] The flow rate transmitted through pipe 6 satisfies:

[0065] X4 = X6 + X7

[0066] Where X2 represents the flow rate transmitted through pipe 2, X4 represents the flow rate transmitted through pipe 4, X5 represents the flow rate transmitted through pipe 5, X6 represents the flow rate transmitted through pipe 6, and X7 represents the flow rate transmitted through pipe 7.

[0067] Starting from the last pipe, pipe 7 transmits flow to heating user 3, and the flow rate transmitted by pipe 7 is the maximum demand flow rate of heating user 3. Pipe 6 transmits flow to heating user 2, and the flow rate transmitted by pipe 6 is the maximum demand flow rate of heating user 2. The flow rate transmitted by pipe 4 is calculated to be the sum of the maximum demand flow rates of heating user 3 and heating user 2. The flow rate range to which the flow rate transmitted by pipe 4 belongs is determined. Based on the optimal flow rate range table for different pipe diameters and the flow rate range to which the flow rate transmitted by pipe 4 belongs, the pipe diameter of pipe 4 is obtained. Pipe 5 transmits flow to heating user 1, and the flow rate transmitted by pipe 5 is the maximum demand flow rate of heating user 1. The flow rate transmitted by pipe 2 is calculated to be the sum of the flow rate transmitted by pipe 4 and the maximum demand flow rate of heating user 1. The flow rate range to which the flow rate transmitted by pipe 2 belongs is determined. Based on the optimal flow rate range table for different pipe diameters and the flow rate range to which the flow rate transmitted by pipe 2 belongs, the pipe diameter of pipe 2 is obtained. The others are similar and will not be repeated here.

[0068] S205: Based on the first pipeline route, the first pipeline diameter, and the load information, calculate the first heating pipe diameter and the first heating flow rate corresponding to each heating user in the first user distribution.

[0069] Specifically, the load information also includes the total annual energy demand of each heating user in the first user distribution. Based on the first pipeline route and the first pipeline diameter, the length of the first heating pipeline and the first heating pipe diameter corresponding to the length of the first heating pipeline are calculated for each heating user in the first user distribution. The length of the first heating pipeline represents the pipeline length between the first pipeline route accessed by each heating user in the first user distribution and the branch point closest to the first pipeline route. The total annual energy demand of each heating user in the first user distribution is divided by the length of the first heating pipeline corresponding to each heating user in the first user distribution to obtain the first heating flow rate corresponding to the first heating pipe diameter. The first heating flow rate is used to determine whether each heating user in the first user distribution adopts a centralized heating method.

[0070] In this embodiment of the application, the first heating flow rate satisfies:

[0071] Y i =D sum,i ÷L i

[0072] Among them, Y i D represents the first heating flow rate corresponding to the first heating pipe diameter of the i-th heating user in the first user distribution. sum,i L represents the total annual energy demand of the i-th heating user in the first user distribution. iLet represent the length of the first heating pipe corresponding to the i-th heating user in the first user distribution, where i represents the number of all heating users in the first user distribution.

[0073] S206: Determine whether the first heating flow rate corresponding to the first heating pipe diameter of each heating user in the first user distribution is greater than or equal to the preset threshold corresponding to the first heating pipe diameter.

[0074] If the first heating flow rate corresponding to the first heating pipe diameter of each heating user in the first user distribution is greater than or equal to the preset threshold corresponding to the first heating pipe diameter, then execute S207; if the first heating flow rate corresponding to the first heating user in the first user distribution is less than the preset threshold corresponding to the first heating pipe diameter, then execute S208.

[0075] S207: Determine that each heating user in the first user distribution adopts centralized heating, and determine the first pipeline route and the first pipeline diameter as the target heating pipeline.

[0076] Specifically, based on the first heating flow rate corresponding to the first heating pipe diameter and the preset threshold corresponding to the first heating pipe diameter for each heating user in the first user distribution, it is determined whether each heating user in the first user distribution adopts centralized heating. When the first heating flow rate corresponding to the first heating pipe diameter for each heating user in the first user distribution is greater than or equal to the preset threshold corresponding to the first heating pipe diameter, it is determined that each heating user in the first user distribution adopts centralized heating. Each heating user in the first user distribution can access the heat source point through the first pipeline route. Therefore, the first pipeline route and the first pipeline diameter are determined as the target heating pipeline network.

[0077] S208: Delete the first heating user from the first user distribution to obtain the second user distribution, and delete the first pipeline route connecting the first heating user from the first pipeline route to obtain the second pipeline route.

[0078] Specifically, when the first heating flow rate corresponding to the first heating user in the first user distribution is less than the preset threshold corresponding to the first heating pipe diameter, it is determined that the first heating user adopts a decentralized heating method, and the first heating user does not need to connect to the heat source point through the first pipeline route. The first heating user is deleted from the first user distribution to obtain the second user distribution, and the first pipeline route connecting to the first heating user is deleted from the first pipeline route to obtain the second pipeline route.

[0079] S209: Based on the load information, calculate the second flow rate corresponding to each second pipeline route in the second pipeline network, and determine the diameter of the second pipeline network based on the flow range to which the second flow rate belongs.

[0080] Specifically, based on the maximum demand flow corresponding to each heating user in the second user distribution, the calculation starts from the last second pipeline route in the second pipeline network route to obtain the second flow corresponding to each second pipeline route in the second pipeline network route. The flow range to which the second flow of each second pipeline route in the second pipeline network route belongs is determined. Based on the flow range to which the second flow of each second pipeline route in the second pipeline network route belongs and the preset pipe diameter range corresponding to the flow range, the pipe diameter of the second pipeline network is determined. The specific calculation process is detailed in step S204 above and will not be repeated here.

[0081] S210: Based on the second pipeline route, the second pipeline diameter, and load information, calculate the second heating pipe diameter and the second heating flow rate corresponding to each heating user in the second user distribution.

[0082] Specifically, based on the second pipeline route and the second pipeline diameter, the second heating pipeline length and the second heating pipeline diameter corresponding to each heating user in the second user distribution are calculated. The second heating pipeline length represents the pipeline length between the second pipeline route accessed by each heating user in the second user distribution and the branch point closest to the second pipeline route. The total annual energy demand corresponding to each heating user in the second user distribution is divided by the second heating pipeline length corresponding to each heating user in the second user distribution to obtain the second heating flow rate corresponding to the second heating pipeline diameter. The second heating flow rate is used to determine whether each heating user in the second user distribution adopts a centralized heating method. The specific calculation process is described in step S205 above and will not be repeated here.

[0083] S211: If each heating user in the second user distribution adopts centralized heating, then the second pipeline route and the second pipeline diameter are determined as the target heating pipeline.

[0084] Specifically, if the second heating flow rate corresponding to the second heating pipe diameter of each heating user in the second user distribution is greater than or equal to the preset threshold corresponding to the second heating pipe diameter, then it is determined that each heating user in the second user distribution adopts the centralized heating method. Each heating user in the second user distribution can access the heat source point through the second pipeline route. Therefore, the second pipeline route and the second pipeline diameter are determined as the target heating pipeline.

[0085] Optionally, when the second heating flow rate corresponding to the second heating user in the second user distribution is less than the preset threshold corresponding to the second heating pipe diameter, it is determined that the second heating user adopts a decentralized heating method. This will cause the heating users adopting the centralized heating method in the planning area to change, and the heating pipe diameter and the heating flow rate corresponding to each heating user adopting the centralized heating method will change. It is necessary to redetermine the distribution of heating users adopting the centralized heating method until the heating users adopting the centralized heating method in the planning area no longer change. At this time, the target heating network connected to the heat source point is determined.

[0086] Using the embodiments of this application, the route of the heating network is planned according to the location of the heat source points in the planning area and the distribution of heating users using centralized heating. Based on the load information, the heating users using centralized heating and the heating users using decentralized heating in the first user distribution are determined. The heating users using centralized heating are connected to the target heating network. Centralized heating and / or decentralized heating are adopted according to the heating user needs in the planning area, which can reduce heat loss and improve utilization.

[0087] like Figure 4 As shown, Figure 4 This is a schematic diagram of a thermal pipeline planning device provided in an embodiment of this application. The thermal pipeline planning device includes an acquisition module 401 and a processing module 402. Detailed descriptions of each unit are as follows.

[0088] Acquisition module 401: used to acquire the location of heat source points, the distribution of first users and load information of the planning area, wherein the load information includes the maximum demand flow and the total annual energy demand of each heating user in the first user distribution.

[0089] Optionally, the acquisition module 401 is also used to acquire the preset range of pipe diameters corresponding to different flow intervals and the preset thresholds corresponding to different heating pipe diameters. It should be understood that by calculating the heating flow rate corresponding to each pipeline route, the pipe diameter of each pipeline route is determined according to the preset range of pipe diameters corresponding to different flow intervals, so that each pipeline route is in the optimal flow range; the preset thresholds corresponding to different heating pipe diameters are used to determine whether each heating user in the first user distribution adopts the centralized heating method.

[0090] Processing module 402: used to preset the main pipeline route and branch pipeline route based on the location of the heat source and the distribution of the first user.

[0091] Specifically, the location of the heat source is determined to be in the first direction of the planning area; based on the first user distribution, a main pipeline route is preset on the road closest to the heat source and parallel to the first direction, and a first branch pipeline route is preset on the road closest to the heat source and perpendicular to the first direction; based on the first direction, a branch pipeline route is preset on every other road parallel to the first branch pipeline route, and a branch pipeline route is preset on the last road parallel to the first branch pipeline route in the planning area.

[0092] Processing module 402 is further configured to determine the main pipeline route connecting to the heating users in the first user distribution from the preset main pipeline route and the branch pipeline route connecting to the heating users in the first user distribution from the preset branch pipeline route as the first pipeline route.

[0093] Processing module 402 is further configured to calculate the first flow rate corresponding to each first pipeline route in the first pipeline network based on the maximum demand flow rate corresponding to each heating user in the first user distribution, and determine the diameter of the first pipeline network based on the flow rate range to which the first flow rate belongs.

[0094] Specifically, based on the maximum demand flow corresponding to each heating user in the first user distribution, starting from the last first pipeline route in the first pipeline network route, the first flow corresponding to each first pipeline route in the first pipeline network route is calculated, and the flow range to which the first flow of each first pipeline route in the first pipeline network route belongs is determined; based on the flow range to which the first flow of each first pipeline route in the first pipeline network route belongs and the preset range of pipe diameter corresponding to the flow range, the pipe diameter of the first pipeline network is determined.

[0095] Processing module 402 is further configured to calculate the first heating pipe diameter and the first heating flow rate corresponding to each heating user in the first user distribution based on the first pipeline route, the first pipeline diameter, and the total annual energy demand of each heating user in the first user distribution.

[0096] Specifically, based on the first pipeline route and the first pipeline diameter, the length of the first heating pipeline and the corresponding first heating pipe diameter for each heating user in the first user distribution are calculated. The first heating pipeline length represents the pipeline length between the first pipeline route accessed by each heating user in the first user distribution and the branch point closest to the first pipeline route. The total annual energy demand for each heating user in the first user distribution is divided by the length of the first heating pipeline corresponding to each heating user in the first user distribution to obtain the first heating flow rate corresponding to the first heating pipe diameter. The first heating flow rate is used to determine whether each heating user in the first user distribution adopts a centralized heating method. The first heating flow rate satisfies:

[0097] Y i =D sum,i÷L i

[0098] Among them, Y i D represents the first heating flow rate corresponding to the first heating pipe diameter of the i-th heating user in the first user distribution. sum,i L represents the total annual energy demand of the i-th heating user in the first user distribution. i Let represent the length of the first heating pipe corresponding to the i-th heating user in the first user distribution, where i represents the number of all heating users in the first user distribution.

[0099] The processing module 402 is further configured to determine that each heating user in the first user distribution adopts a centralized heating method if the first heating flow rate corresponding to the first heating pipe diameter of each heating user in the first user distribution is greater than or equal to the preset threshold corresponding to the first heating pipe diameter, and to determine the first pipeline route and the first pipeline diameter as the target heating pipeline.

[0100] Optionally, the processing module 402 is further configured to: delete the first heating user from the first user distribution and obtain a second user distribution if the first heating flow rate corresponding to the first heating user in the first user distribution is less than a preset threshold corresponding to the first heating pipe diameter; delete the first pipe route connecting to the first heating user from the first pipe network route and obtain a second pipe network route; calculate the second flow rate corresponding to each second pipe route in the second pipe network route based on the maximum demand flow rate corresponding to each heating user in the second user distribution; determine the second pipe network diameter based on the flow range to which the second flow rate belongs; calculate the second heating pipe diameter and the second heating flow rate corresponding to the second heating pipe diameter and the second heating pipe diameter corresponding to each heating user in the second user distribution based on the second pipe network route, the second pipe network diameter, and the total annual energy demand corresponding to each heating user in the second user distribution; if the second heating flow rate corresponding to the second heating pipe diameter of each heating user in the second user distribution is greater than or equal to the preset threshold corresponding to the second heating pipe diameter, determine that each heating user in the second user distribution adopts a centralized heating method, and determine the second pipe network route and the second pipe network diameter as the target heating network.

[0101] Optionally, the processing module 402 is further configured to determine that the first heating user adopts a decentralized heating method if the first heating flow rate corresponding to the first heating user in the first user distribution is less than a preset threshold corresponding to the first heating pipe diameter.
