1 and 2 are a block diagram showing an example of the configuration of the design system 1 according to the embodiment of the present invention and a flow diagram showing an example of the operation, respectively.

With reference to FIG. 1, the design system 1 includes a management device 3. The management device 3 includes a map information acquisition unit 5, a hyper line ledger processing unit 7, an underline information management unit 8, a steel tower position information processing unit 9, a steel tower position display unit 11, and an existing information management unit 13. Vertical section of the slack calculation unit 15, the plan drawing unit 17, the basic map management unit 19, the first CAD unit 21, the steel tower information management unit 23, the survey information management unit 25, and the three-dimensional data processing unit 27. A drawing unit 29 and a second CAD unit 30 are provided. The management device 3 can communicate with various servers and the like using the Internet and the like, and each part can be realized by using a program and the like.

The map information acquisition unit 5 acquires map information. The map information is, for example, basic map information or map information obtained from a geographic information system (GIS). The basic map information is information that serves as a reference for the position in the electronic map. As the basic map information, mesh data such as 5 m mesh and 10 m mesh can be downloaded from a server managed by the Geographical Survey Institute, for example. In the following, the coordinate system that specifies the position in the mesh data is referred to as a plane rectangular coordinate system. The geographic information system comprehensively manages and processes data (spatial data) that has information about the location, using the geographical location as a clue, and enables visual display, advanced analysis, and quick judgment. It is a thing.

The hyper track ledger processing unit 7 stores and manages the hyper track ledger data. As shown in FIG. 2A, information is acquired from each part (step STA1), and a process of maintenance and management is performed (step STA2). In the following, the hyper track ledger data will be described using an example of managing information about a power transmission tower. A power transmission tower in which a power transmission line is erected between them is referred to as an adjacent power transmission tower (an example of an "adjacent building" in the claims of the present application). In this embodiment, the transmission tower is supported by a plurality of legs, and the foundation may be integrated or separated. It should be noted that the present invention relates to, for example, a thing in which a linear member such as a wire is hung between a plurality of buildings (for example, a thing in which a wire is hung between a plurality of buildings such as a pillar of a ski lift). May be.

The hyper track ledger data manages the center position of the steel tower by associating the latitude / longitude information with the coordinate information in the plane rectangular coordinate system. For example, if one is input, the other is generated and managed by the conversion process. In map data and survey information, spatial positions are usually specified by latitude / longitude or plane orthogonal coordinate systems. By using the hyper track ledger data, the center position of the tower can be appropriately specified for various map data and survey information.

Also, the true direction at the center of the tower (true direction; for example, true north is true meridian; hereinafter referred to as true north) and magnetic direction (direction specified by the azimuth magnetic needle. For example, magnetic north is the meridian of geomagnetism. Then, let's assume magnetic north) and manage the deviation. The formula for calculating magnetic north is open to the public, and it can be used to calculate magnetic north at each center position. In addition, it contains data that identifies the shape of the tower, which allows the distance from the center position to each leg.

In addition, the declination between the shape of the tower and true north is specified. Towers generally change direction depending on their relationship with the adjacent tower. It is often installed so that the angles formed by the wires on both sides are even, but for example, when the distance is far or at the end, it is installed so that it faces the adjacent power transmission tower of the young or old number. It may be done. Therefore, the position of each leg is suitable for specifying by the declination and the distance to true north like the polar coordinates using the center position. The hyper track ledger data manages the deviation between true north and magnetic north. Therefore, by using the hyper track ledger data, it is possible to obtain the declination angle and the distance from the center position to the magnetic north of each leg. Workers who reconnaissance the tower can identify the deviation angle and distance from the center position to the magnetic north of each leg by using the map data using the hyper track ledger data in the field survey, and at the center position of the tower. If you stand and look at each leg using a compass glass, you can check the deviation angle and distance from the magnetic north, which makes the work extremely easy.

Intuitively, it seems that the center position of the tower can be easily identified. However, the center position of the tower is usually investigated in the field. Since the earth is round, for example, even if it travels 5 km to the north, 5 km to the west, 5 km to the south, and 5 km to the east, it usually does not return to its original place. In particular, the spacing between transmission towers is extremely large compared to the spacing between mesh data (5m, 10m, etc.), and the error is not negligible. The position of the transmission tower recognized by the field survey has an error with the position specified by the latitude and longitude, and has an error with the position in the plane orthogonal coordinate system such as mesh data. The latitude / longitude at the position of the transmission tower and the position in the Cartesian coordinate system (for example, the relationship with the distance) need to be individually adjusted according to the position where the transmission tower exists. The hyper line ledger data manages the accurate correspondence between the latitude / longitude information and the coordinate information in the plane rectangular coordinate system for the center position of the steel tower in consideration of this error.

The underline information management unit 8 manages underline information that identifies a transmission facility or the like existing under a transmission line built between transmission towers. For example, when an outside light is present, the position (coordinates, latitude / longitude, etc. in the plane orthogonal coordinate system) and altitude of the outside light are specified. The vertical section drawing unit 29 uses the underline information together with the survey information about the tree when creating the vertical section drawing of the transmission line. The survey information may be included in addition to the underline information. The floor plan drawing unit 17 may also use the underline information as needed.

The tower position information processing unit 9 can be realized by, for example, mountain climbing map software, and performs a process of specifying the center position of the tower. The steel tower position display unit 11 displays the center position of the steel tower specified by the hyper track ledger data by using a map search service on the Internet or the like. The accuracy of the center position of the tower specified by the tower position information processing unit 9 can be confirmed.

The existing information management unit 13 manages the existing information used in the management of the tower, such as the tower margin table, the tower shape diagram, and the location information of the Kyushu area. Since the existing information is managed in relation to each tower by the hyper track ledger data, the hyper track ledger processing unit 7 can easily generate the tower information 33 (for example, tower direction map, tower shape map, environmental information map, etc.). can do.

The slack calculation unit 15 specifies the position of the tower using the hyper line ledger data, and calculates the slack of the transmission line between the transmission towers. The vertical section drawing unit 29 can obtain information on the position of the transmission line between the transmission towers by using the slackness.

Furthermore, the plan view and the vertical section view have traditionally been based on field surveys. Therefore, it was created by investigating the center line connecting the adjacent transmission towers as a basis and investigating the surrounding area if necessary. As a result, the plan view was originally two-dimensional, but was expressed as a strip-shaped one-dimensional data centered on the transmission line. In addition, the vertical profile had to be of low accuracy, such as keeping the height of trees in a certain section constant. On the other hand, in this embodiment, since the center position of the iron tower can be accurately managed by the hyper track ledger data, the plan view 31 and the vertical section view 35 also have high accuracy in consideration of the original two-dimensional and three-dimensional states. Can be generated with.

When the floor plan drawing unit 17 is instructed to draw the floor plan (YES in step STB1 in FIG. 2B), the floor plan drawing unit 17 may specify the range to be created for the basic map management unit 19 or the first CAD unit 21. To draw a plan view by transmitting information about the tower (step STB2). The basic map management unit 19 sends the range specified by the plan drawing unit 17 to the first CAD unit 21 with respect to the data acquired from the geographic information system or the like. The first CAD unit 21 adds information about the steel tower received from the plan drawing unit 17 to the data received from the basic map management unit 19, so that the computer-aided design can be performed. The first CAD unit 21 can generate various types of plan views 31 according to the instructions of the operator.

The survey information management unit 25 manages the survey information obtained by the field survey. For example, it manages survey information obtained by laser surveying and aerial photography surveying. The three-dimensional data processing unit 27 uses the hyper track ledger data to add survey information to the mesh data and perform processing. The hyper line ledger processing unit 7 and / or the three-dimensional data processing unit 27 includes, for example, the state of the transmission line obtained in the survey information in addition to the information obtained by the slack calculation unit 15 for the transmission line. May be managed.

When the vertical section drawing unit 29 receives an instruction for vertical section drawing (YES in step STC1 in FIG. 2C), the second CAD uses the mesh data to which the survey information is added by the three-dimensional data processing unit 27. Information about the steel tower is transmitted to the unit 30 to draw a vertical profile (step STC2). The second CAD unit 30 can draw various types of longitudinal views 35 according to the instructions of the operator.

The tower information management unit 23 manages information about the tower (plan view 31, tower information 33, longitudinal view 35, etc.) and distributes it as data such as a PDF in response to a request from another information processing terminal, for example. can.

As shown in FIG. 5A, it is necessary to secure the ground height of the transmission line in the transmission tower. Conventionally, as shown in FIGS. 5 (b) and 5 (c), the center line of a transmission line is measured by transit, and the surface crossing the center line is measured at a portion determined to be necessary at the site. As shown in FIG. 5D, since the exact tree height cannot be determined, the tree height was estimated from the measured maximum altitude. In addition, because the number of measurements was small, it was divided into multiple sections, and the height of the trees was constant within the sections.

The applicant has found that carrying a radar surveying instrument on his back for measurement is suitable for longitudinal surveying of transmission lines. FIG. 6 is a new surveying method proposed by the applicant. The survey information management unit 25 manages information indicating the survey result.

The surveying instrument can perform self-position estimation and spatial recognition, and automatically measure the height of the ground surface, the height of trees, and the height of transmission lines. As shown in FIG. 6B, information indicating the height of the ground surface, the height of trees, and the height of transmission lines is referred to as DTM data, DSM data, and equipment data. The height of the tree may include the height of the power transmission facility under the line. 6 (c) and 6 (d) show DTM data and DSM data obtained by classifying the measurement results, respectively. 6 (e) and 6 (f) show three-dimensional data obtained by using DTM data and DSM data, respectively.

FIG. 14 is a diagram showing an example of tower information 33. 14 (a) and 14 (b) show a tower direction diagram and a tower shape diagram, respectively. These diagrams can be easily created by using the hyper track ledger data. Similarly, as an environmental information map, a map including information such as an airport can be easily generated.

FIG. 15 is a diagram for explaining the reconnaissance of the steel tower. FIG. 15A is for explaining a conventional reconnaissance. In conventional tower reconnaissance, workers used maps to conduct surveys. The map is based on true north. Therefore, it was necessary to adjust the direction considering the difference between magnetic north and true north. Furthermore, the red and white poles were placed in the direction perpendicular to the track direction, the red and white poles were placed in the leg direction in consideration of the installation direction of the tower, and the leg direction was investigated with a winding scale and a clinometer. Therefore, extremely complicated work was required.

FIG. 15B is for explaining the work using the hyper track ledger data.
