Description

Technical Field

[0001] The present invention relates to the technical field of road planning, and in particular to a planning method, device and equipment for a temporary construction road of a power transmission line. Background Art

[0002] With the development of my country's economic construction and power grid construction, the construction environment of transmission lines is becoming increasingly complex. Transmission line projects generally have long paths and large spans, and the lines are often set up in a variety of terrains. For each transmission line project, it is often necessary to build temporary construction roads to assist the construction of the transmission line project. Temporary construction roads are usually determined based on the experience of technical personnel. The temporary construction roads may be changed due to terrain reasons, resulting in increased workload, and the temporary construction roads determined by personal experience may not be the optimal solution, resulting in a waste of manpower and material resources. Summary of the invention

[0003] In view of this, the present invention provides a method, device and equipment for planning a temporary construction road for a power transmission line, so as to solve the problem of high manpower and material costs caused by transporting construction materials.

[0004] In a first aspect, the present invention provides a method for planning a temporary construction road for a transmission line, the method comprising:

[0005] Acquire information of a transmission line to be constructed, the information of the transmission line to be constructed including information of at least one tension section and information of a highway within a preset range of distance from the transmission line to be constructed;

[0006] For each tension section, multiple pre-unloading points are selected within a preset range according to preset requirements, and the shortest paths from multiple pre-unloading points to the material station are determined using a preset path planning algorithm based on the corresponding tension section information, multiple pre-unloading points, and highway information within a preset range from the line to be constructed. The material station is a temporary storage location for transmission line construction materials.

[0007] Multiple temporary construction roads are formed according to the shortest paths from multiple pre-unloading points to the material station, and the manpower transport distance corresponding to each temporary construction road is calculated using a preset manpower transport distance algorithm;

[0008] The manpower transport distances corresponding to various temporary construction roads are compared, and the temporary construction road with the smallest manpower transport distance is taken as the optimal temporary construction road for the corresponding tension section.

[0009] The planning method for temporary construction roads of power transmission lines provided by the present invention determines the shortest paths from multiple pre-unloading points to the material station, then calculates the manpower transportation distance of each temporary construction road according to each shortest path, and finally determines the optimal temporary construction road for the corresponding tension section, thereby reducing manpower and material costs and improving the efficiency of project cost management.

[0010] In an optional implementation, for each tension section, multiple pre-discharging points are selected within a preset range according to preset requirements, including:

[0011] Visualize the information of the line to be constructed and obtain the engineering image of the line to be constructed and its preset range;

[0012] Select multiple pre-unloading points on the engineering image according to the distance to the construction point of the tension section.

[0013] The planning method of temporary construction roads for power transmission lines provided by the present invention performs visualization processing on the information of the construction lines, simulates and selects multiple pre-unloading points in the engineering image, and the distance between the positions of the pre-unloading points and the construction points of the tension sections is as short as possible. The temporary construction roads are determined by a dynamic management method, thereby ensuring that the manpower and material resources of the power transmission line project are reduced by selecting the pre-unloading points.

[0014] In an optional implementation, according to the corresponding tension section information, multiple pre-unloading points, and highway information within a preset range of distance from the line to be constructed, a preset path planning algorithm is used to respectively determine the shortest paths from multiple pre-unloading points to the material station, including:

[0015] Determine the adjacent highway of the corresponding tension section according to the corresponding tension section information and the highway information within a preset range, wherein the adjacent highway is the highway with the shortest distance from the tension section;

[0016] For each pre-unloading point, the optimal passing point corresponding to the pre-unloading point is determined on the adjacent highway according to the preset rules;

[0017] The path from each pre-unloading point through the corresponding optimal waypoint to the material station is taken as the shortest path from each pre-unloading point to the material station.

[0018] The planning method for temporary construction roads of power transmission lines provided by the present invention selects the optimal passing point on the adjacent highway, and then determines the shortest path from each pre-unloading point to the material station, and then determines the path of the temporary construction road, ensuring that the planning of the temporary construction road makes the path from the corresponding pre-unloading point to the material station the shortest, so as to improve the construction efficiency.

[0019] In an optional implementation, for each pre-unloading point, determining the optimal waypoint corresponding to the pre-unloading point on the adjacent highway according to a preset rule includes:

[0020] For each pre-unloading point, multiple passing points are selected on the adjacent highway according to the preset step length;

[0021] Use the preset path planning algorithm to calculate the cost from the pre-unloading point through each waypoint to the material station;

[0022] Compare the sizes of multiple cost values ​​and select the waypoint with the smallest cost value as the optimal waypoint corresponding to the pre-unloading point.

[0023] The planning method for temporary construction roads of power transmission lines provided by the present invention calculates the cost value of the corresponding pre-unloading point when each point on the adjacent highway is used as a waypoint, and selects the waypoint with the smallest cost value as the optimal waypoint for each pre-unloading point, thereby ensuring the shortest path from the pre-unloading point to the material station and improving the transportation efficiency of construction materials.

[0024] In an optional implementation, a preset path planning algorithm is used to calculate the cost of reaching the material station from the pre-unloading point through the waypoint, including:

[0025] Determine the path from the pre-unloading point to the passing point based on the highway information and pre-unloading point information within the preset distance range from the line to be constructed;

[0026] According to the path from the pre-unloading point to the waypoint, the preset cost function is used to calculate the cost from the pre-unloading point through the waypoint to the material station;

[0027] The default cost function is:

[0028] f(n)=g(n)+h(n)

[0029] Among them, f(n) represents the cost of the pre-unloading point, g(n) represents the path length from the pre-unloading point to the waypoint, and h(n) represents the estimated path length from the waypoint to the material station.

[0030] The planning method for temporary construction roads of power transmission lines provided by the present invention uses a preset cost function to calculate the cost of each pre-unloading point passing through a waypoint to reach a material station, thereby improving the calculation efficiency and accuracy and making the calculation result more meaningful for reference.

[0031] In an optional implementation, the manpower transport distance corresponding to each temporary construction road is calculated using a preset manpower transport distance algorithm, including:

[0032] Obtaining terrain information within a preset range from the line to be constructed;

[0033] Based on at least one tension section information and highway information and terrain information within a preset range of the line to be constructed, the human transportation distance of the line to be constructed is determined. The human transportation distance is the average human transportation distance for transporting construction materials from a unloading point on the highway to a construction point by manpower.

[0034] The planning method for temporary construction roads of power transmission lines provided by the present invention determines the optimal temporary construction road for each tension section by calculating the manpower transportation distance, thereby reducing the waste of manpower and material resources during the construction of each tension section. By adding terrain factors to the calculation of the manpower transportation distance, the calculation result of the manpower transportation distance is made more accurate, and it is more reasonable to determine the optimal temporary construction road by the manpower transportation distance.

[0035] In a second aspect, the present invention provides a planning device for a temporary construction road of a transmission line, the device comprising:

[0036] An information acquisition module, used to acquire information about the transmission line to be constructed, the information about the transmission line to be constructed including information about at least one tension section and information about a highway within a preset range of distance from the transmission line to be constructed;

[0037] The shortest path determination module is used to select multiple pre-unloading points within a preset range for each tension section according to preset requirements, and use a preset path planning algorithm to determine the shortest paths from multiple pre-unloading points to a material station based on the corresponding tension section information, multiple pre-unloading points, and highway information within a preset range from the line to be constructed. The material station is a temporary storage location for transmission line construction materials;

[0038] The transport distance calculation module is used to form multiple temporary construction roads according to the shortest paths from multiple pre-unloading points to the material station, and calculate the manpower transport distance of each temporary construction road using a preset manpower transport distance algorithm;

[0039] The optimal solution determination module is used to compare the manpower transportation distances corresponding to various temporary construction roads, and take the temporary construction road with the smallest manpower transportation distance as the optimal temporary construction road for the corresponding tension section.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0049] The embodiments of the present invention provide a method, device and equipment for planning a temporary construction road for a transmission line, which determines the temporary construction road by reasonably selecting waypoints and unloading points to reduce the waste of manpower and material resources caused by transporting construction materials during the construction process.

[0050] According to an embodiment of the present invention, an embodiment of a method for planning a temporary construction road for a transmission line is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0051] In this embodiment, a method for planning a temporary construction road for a transmission line is provided, which can be used in the above-mentioned computer system. Figure 1 is a flow chart of a method for planning a temporary construction road for a transmission line according to an embodiment of the present invention. Figure 1As shown, the process includes the following steps:

[0052] Step S101, obtaining information of a transmission line to be constructed, wherein the information of the transmission line to be constructed includes information of at least one tension section and information of a highway within a preset range from the transmission line to be constructed.

[0053] Specifically, by importing a Keyhole Markup Language (KML) file containing geographic information within a preset range of distance from the line to be constructed into the Geographic Information System (GIS) software, the line information to be constructed of the transmission line is obtained, and the line information to be constructed includes but is not limited to: at least one tension section information constituting the line to be constructed, and highway information and terrain information within a preset range of distance from the line to be constructed. The line information to be constructed can be displayed in the form of a data list or an interface image, or in a combination of multiple forms, which is only taken as an example, but not limited to this.

[0054] In the geographic information system software, strain towers and straight towers are identified by specific tags or attribute values. There are multiple straight towers between every two strain towers, and there are strain sections between the strain towers. The strain sections that constitute the line to be constructed are determined by identifying the strain towers. The strain section is the basic management unit of the power line. Therefore, this implementation uses the strain section as the basic planning unit for road planning.

[0055] Step S102, for each tension section, select multiple pre-unloading points within a preset range according to preset requirements, and use a preset path planning algorithm to determine the shortest paths from the multiple pre-unloading points to the material station, which is a temporary storage location for transmission line construction materials, based on the corresponding tension section information, multiple pre-unloading points and highway information within a preset range from the line to be constructed.

[0056] Specifically, for the line to be constructed, the corresponding tension section needs to be determined according to the construction point. For each tension section to be constructed, a temporary construction road needs to be planned to assist in the construction of the corresponding tension section. The function of the temporary construction road is to bring the unloading point of the tension section as close to the construction point as possible to reduce manpower and material resources. In this embodiment, the position of the material station is fixed, but there may be multiple positions of the pre-unloading point, so it is necessary to use a preset path planning algorithm to calculate the shortest path from each pre-unloading point to the material station, so as to facilitate comparison between multiple pre-unloading points.

[0057] Step S103, forming multiple temporary construction roads according to the shortest paths from multiple pre-unloading points to the material station, and calculating the manpower transport distance corresponding to each temporary construction road using a preset manpower transport distance algorithm.

[0058] Specifically, after the location of the pre-unloading point and the shortest path to the material station are determined, the non-highway section of the shortest path is the temporary construction road. The preset manpower transport distance algorithm is used to calculate the manpower transport distance corresponding to each temporary construction road, and then the effect of the corresponding temporary construction road on the construction is determined.

[0059] Step S104, comparing the manpower transport distances corresponding to the temporary construction roads, and taking the temporary construction road with the smallest manpower transport distance as the optimal temporary construction road for the corresponding tension section.

[0060] Specifically, the manpower transport distance reflects the manpower cost required during construction. By comparing the manpower transport distances corresponding to the temporary construction roads, and taking the temporary construction road with the smallest manpower transport distance as the optimal temporary construction road for the corresponding tension section, the manpower cost is reduced. The optimal temporary construction roads for each tension section are calculated separately, and the final transmission line construction includes at least one temporary construction road. The temporary construction lines do not affect each other. After a temporary construction road is calculated, the new temporary construction road can be used as an existing highway to calculate the subsequent temporary construction roads. This is only an example, but not limited to this.

[0061] The planning method for temporary construction roads of transmission lines provided in this embodiment determines the shortest paths from multiple pre-unloading points to the material station, and then calculates the manpower transportation distance of each temporary construction road according to each shortest path, and finally determines the optimal temporary construction road corresponding to the tension section, thereby reducing labor costs and improving construction efficiency.

[0062] In this embodiment, a method for planning a temporary construction road for a transmission line is provided, which can be used in the above-mentioned computer system. Figure 2 is a flow chart of a method for planning a temporary construction road for a transmission line according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0063] Step S201, obtaining the information of the transmission line to be constructed, the information of the transmission line to be constructed includes at least one tension section information and the information of the highway within a preset range from the transmission line to be constructed. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0064] Step S202: for each tension section, multiple pre-unloading points are selected within a preset range according to preset requirements, and based on the corresponding tension section information, multiple pre-unloading points and highway information within a preset range from the line to be constructed, a preset path planning algorithm is used to determine the shortest paths from the multiple pre-unloading points to the material station, which is a temporary storage location for transmission line construction materials.

[0065] Specifically, the above step S202 includes:

[0066] Step S2021, visualizing the information of the line to be constructed to obtain an engineering image of the line to be constructed and within a preset range.

[0067] Specifically, GIS software is used to visualize the information of the line to be constructed, and the information of the tension section of the line to be constructed and the information of the highway within a preset range from the line to be constructed are intuitively displayed. This helps to accurately grasp the situation around the line to be constructed, and select a suitable location close to the construction point as the pre-unloading point based on the construction point of the tension section and the distance between the highway and the construction point. The suitable location is selected by the construction personnel based on their experience, and the suitable location is close to the construction point and within a range where the highway and the construction point are relatively close.

[0068] Step S2022, selecting a plurality of pre-unloading points on the engineering image according to the distance to the construction point of the tension section.

[0069] Specifically, the location of the specific pre-unloading point can be manually selected based on experience at a point close to the construction point, or can be determined by software distance measurement, which is only taken as an example, but not limited to this. Due to the influence of the terrain, buildings, obstacles, etc. of the construction line and its surroundings, the pre-unloading point closest to the construction point may not be the optimal solution, so multiple pre-unloading points are selected according to the distance to the tension section construction point.

[0070] The method for planning temporary construction roads for transmission lines provided in this embodiment visualizes the information of the construction line to be constructed, selects multiple pre-unloading points based on the project image and the distance to the construction point of the tension section, and the distance between the position of the pre-unloading point and the construction point of the tension section is as short as possible, thereby ensuring that the manpower and material resources of the transmission line project are reduced by selecting the pre-unloading points.

[0071] Step S2023, determining the adjacent highway of the corresponding tension section according to the corresponding tension section information and the highway information within a preset range, wherein the adjacent highway is the highway with the shortest distance from the tension section.

[0072] Specifically, in order to ensure that the direct manpower transportation distance is minimized, the materials required for construction need to be placed on the road closest to the line to be constructed. The tension section is the basic unit of the line to be constructed, so the adjacent roads of each tension section need to be determined first. The specific determination method can be manually selected through three-dimensional images, or automatically selected through image recognition and other means. This is only an example, but not limited to this.

[0073] Step S2024: for each pre-unloading point, determine the optimal passing point corresponding to the pre-unloading point on the adjacent highway according to preset rules.

[0074] Specifically, the pre-unloading point is used to transport the construction materials from the material station to the pre-unloading point, and then transport them from the pre-unloading point to the construction site. The pre-unloading point is in the non-highway area, so it is necessary to determine the connection point from the pre-unloading point to the adjacent highway, that is, the junction of the temporary construction road and the adjacent highway. For each pre-unloading point, the optimal passing point corresponding to the pre-unloading point is determined on the adjacent highway according to the preset rules.

[0075] In some optional implementations, the above step S2024 includes:

[0076] Step a1: for each pre-unloading point, multiple waypoints are selected on the adjacent highway according to a preset step length.

[0077] Step a2, using a preset path planning algorithm to calculate the cost of reaching the material station from the pre-unloading point through each waypoint.

[0078] In some optional implementations, the above step a2 includes:

[0079] Step a21, determining the path from the pre-unloading point to the passing point according to the highway information within a preset range from the line to be constructed and the pre-unloading point information.

[0080] Specifically, to ensure the feasibility and safety of the construction road, factors such as terrain, existing obstacles, and the size of construction equipment are considered. A path from the pre-unloading point to the passing point is planned manually or automatically by software. The path planning service and the construction road design software automatically call the Application Programming Interface (API) of the path planning service of Amap, and intelligently plan a path from the adjacent highway to the pre-unloading point according to the specified pre-unloading point location. For the terrain, the impact of the terrain undulation on the slope of the construction road is considered, and the path with a gentler slope is preferred. The spatial analysis function of the GIS software is used to automatically avoid obstacles such as existing buildings and rivers, which is only an example, but not limited to this.

[0081] Step a22, according to the path from the pre-unloading point to the waypoint, a preset cost function is used to calculate the cost of reaching the material station from the pre-unloading point via the waypoint.

[0082] The default cost function is:

[0083] f(n)=g(n)+h(n)

[0084] Among them, f(n) represents the cost of the pre-unloading point, g(n) represents the path length from the pre-unloading point to the waypoint, and h(n) represents the estimated path length from the waypoint to the material station. Euclidean distance can be used as a heuristic estimate, which is only an example but not limited to this.

[0085] Specifically, the A-star algorithm can be used to determine the shortest path from the pre-unloading point to the material station through the waypoint. The A-star algorithm is an efficient path search algorithm widely used in the field of graph planning. It finds the shortest path from the starting point (pre-unloading point) to the target point (material station) by evaluating the cost of each node (waypoint) in the graph. The specific process includes:

[0086] (1) Determine the location of the pre-unloading point and the material station, and initialize two lists: the open list is used to store the nodes to be evaluated (the waypoints on the adjacent highway), and the closed list is used to store the nodes that have completed the evaluation;

[0087] (2) For the pre-unloading point, when different waypoints are selected, the cost value of the pre-unloading point is calculated using the preset cost function. It should be noted that h(n) in the preset cost function is generally replaced by the Euclidean distance from the waypoint to the material station;

[0088] (3) Select the node with the lowest cost value in the open list for expansion. For all adjacent nodes of the current node, calculate the path length from the pre-unloading point to the waypoint when each adjacent node is used as a waypoint. If the g(n) calculated by the adjacent node as a waypoint is less than the g(n) calculated by the current node as a waypoint, then add the adjacent node to the open list.

[0089] (4) Repeat the above step (3) until the location of the material station is added to the closed list, or the open list is empty. The location of the material station is added to the closed list, indicating that a path from the pre-unloading point to the material station has been found. The open list is empty, indicating that there is no feasible path to reach the target point.

[0090] (5) If the location of the material station is added to the closed list, the shortest path is reconstructed from the material station in reverse by backtracking the nodes in the closed list.

[0091] The method for planning temporary construction roads for transmission lines provided in this embodiment uses a preset cost function to calculate the cost of each pre-unloading point passing through a waypoint to reach a material station, thereby improving calculation efficiency and accuracy and making the calculation results more meaningful for reference.

[0092] Step a3, compare the sizes of multiple cost values, and select the waypoint with the smallest cost value as the optimal waypoint corresponding to the pre-unloading point.

[0093] The planning method for temporary construction roads of transmission lines provided in this embodiment calculates the cost value corresponding to the pre-unloading point when each point on the adjacent highway is used as a waypoint, and selects the waypoint with the smallest cost value as the optimal waypoint for each pre-unloading point, thereby ensuring the shortest path from the pre-unloading point to the material station and improving the transportation efficiency of construction materials.

[0094] Step S2025: The path from each pre-unloading point through the corresponding optimal waypoint to the material station is used as the shortest path from each pre-unloading point to the material station.

[0095] Specifically, the path from each pre-unloading point to the optimal waypoint is a temporary construction road, and the optimal waypoint and the shortest path of each pre-unloading point are output in the form of a graph or report for reference and decision-making by the construction unit.

[0096] Through the graphical user interface (GUI) of the software tool, the selection of each pre-unloading point can be determined by manual dragging, which is only an example, but not limited to this. For the planned temporary construction roads, they can be further manually adjusted through the GUI to adapt to specific construction needs or site conditions. The manual adjustments include but are not limited to dragging road segments, adding or deleting curves, adjusting road width, etc. It can adapt to terrain changes during the construction process and the construction of temporary construction roads, and has better practicality. After manually adjusting the temporary construction road, the currently planned plan can be saved in the project file for user review.

[0097] The planning method for temporary construction roads of transmission lines provided in this embodiment selects the optimal passing point on the adjacent highway, and then determines the shortest path from each pre-unloading point to the material station, and then determines the path of the temporary construction road, ensuring that the planning of the temporary construction road makes the path from the corresponding pre-unloading point to the material station the shortest, so as to improve construction efficiency.

[0098] Step S203, forming a plurality of temporary construction roads according to the shortest paths from the plurality of pre-unloading points to the material station, and calculating the manpower transport distance of each temporary construction road using a preset manpower transport distance algorithm.

[0099] Specifically, the above step S203 includes:

[0100] Step S2031, obtaining terrain information within a preset range from the line to be constructed.

[0101] Specifically, since the terrain will affect the planning of temporary construction roads and the calculation of manpower transportation distance, it is necessary to obtain terrain information within a preset range of distance from the line to be constructed. When calculating the manpower transportation distance, the curvature coefficient of the path from the construction point to the pre-unloading point is determined according to the terrain information. The curvature coefficient refers to the curvature in the transportation path due to the influence of terrain, topography and ground obstacles, including uphill, downhill, winding mountain roads and transportation from one unloading point to multiple transmission towers, which represents the ratio of the actual transportation distance to the straight-line distance. According to the actual situation, a corresponding curvature coefficient is assigned to each terrain type to reflect the impact of different terrains on the manpower transportation distance, and the curvature coefficient of each tension section is determined according to the terrain information from each tension section to the adjacent highway, for example: the curvature coefficient of flat land is 1.05-1.1; the curvature coefficient of swamp is 1.1-1.2; the curvature coefficient of hills is 1.1-1.3; the curvature coefficient of mountainous areas is 1.3-1.5; the curvature coefficient of high mountains and steep mountains is 1.6-1.8; the curvature coefficient of deserts is 1.3-1.5. This is just an example, but not limiting.

[0102] Step S2032, determining the manpower transportation distance of the line to be constructed based on at least one tension section information and the highway information and terrain information within a preset range of the line to be constructed, where the manpower transportation distance is the average manpower transportation distance for transporting construction materials from a unloading point on the highway to a construction point.

[0103] Specifically, the manpower transport distance is a non-highway section and is related to the actual terrain. Therefore, it is necessary to combine the terrain within the preset range of the line to be constructed, the construction point of the line to be constructed and other actual conditions, and use the preset manpower transport distance algorithm to determine the manpower transport distance.

[0104] The calculation formula of the preset manpower distance algorithm used in the embodiment of the present invention is:

[0105]

[0106] Among them, Y j Indicates human transport distance, L j Indicates the amount of line material in each tension section, represented by the length of each tension section, R j The straight-line distance of the materials of each tension section transported by manpower can be represented by the straight-line distance from the construction point of each tension section to the unloading point, and K represents the bending coefficient. This is only an example, but not limited to this.

[0107] For a power transmission line project, after the total amount of construction materials is determined, the third-party supplier of the corresponding construction materials will transport the construction materials to the material station, and use transportation vehicles to transport the construction materials from the material station to the unloading point, and then use manpower to transport the construction materials from the unloading point to the construction point of the line to be constructed. The construction party needs to transport them by themselves. According to the actual project cost requirements, in addition to calculating the manpower transportation distance, the vehicle transportation distance can also be calculated, which can more accurately reflect the construction party’s site transportation costs for transporting construction materials. The vehicle transportation distance is the transportation distance of the transport vehicle on the road. Since the road is fixed, it is only necessary to determine the location of the material station and the unloading point to calculate the vehicle transportation distance. The specific process will not be repeated here. It is only used as an example, but it is not limited to this.

[0108] The planning method for temporary construction roads of transmission lines provided in this embodiment determines the optimal temporary construction road for each tension section by calculating the manpower transportation distance, thereby reducing the waste of manpower and material resources during the construction of each tension section. By adding terrain factors to the calculation of the manpower transportation distance, the calculation result of the manpower transportation distance is made more accurate, and it is more reasonable to determine the optimal temporary construction road by the manpower transportation distance.

[0109] Step S204, compare the manpower transport distances corresponding to the temporary construction roads, and use the temporary construction road with the smallest manpower transport distance as the temporary construction road with the best corresponding tension section. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.
