Description

  The present invention relates to a pipeline information system that manages positional information of pipelines such as water and sewage systems, gas pipes, and valve plugs.

In general, facilities such as water and sewage systems, gas pipes, and valve plugs are managed by describing their installation locations and connections on maps and drawings. With the spread of computers and GIS (Giographic Information System) More and more, maps and facility information are digitized and managed by computers.
For example, when working on-site, such as when a water leakage accident occurs, it is necessary to specify the installation location of the facility, but since many of the target facilities are buried underground, from the ground I can't confirm. For this reason, the installation location of the facility has been managed by describing the distance and depth from the landmark such as the end of the road together.

Japanese Patent No. 2910413 (pages 3 to 6, FIG. 1)

In addition to the above reasons, the management of the installation location of the facility places importance on the visibility of the map for business operations and the problem of the accuracy of the map describing the roads and buildings itself. The coordinates that indicate the installation location were not always accurate.
On the other hand, in recent years, with the widespread use of high-precision GPS, it has become possible to specify the absolute coordinates of a place to be measured with high precision and ease (see Patent Document 1). Along with this, when managing the installation location of facilities or performing work on site, the position accuracy is improved using GPS together with the relative position with other facilities and roads such as conventional connection relations. It is necessary to identify the location of the target facility.

  The present invention has been made to solve the above-described problems, and management of facility data based on absolute positions is possible while maintaining a connection relationship with other facilities and a relative position with other facilities and roads. The purpose is to obtain a pipeline information system.

In the pipeline information system according to the present invention, a facility database storing facility data of pipelines having a first coordinate based on a relative position relative to another facility and a second coordinate based on an absolute position, two types Facility data display switching operation means for selecting one or both of the coordinates, a map database storing map data, a map data display switching operation means for specifying the range and scale of map data to be displayed, and this map data display switching operation map data reading means out viewing the map database or Ra読 map data specified by means, a facility data having the coordinates selected by the facility data display switching operation unit, the range specified by the map data display switching operation unit And facility data reader that reads facility data corresponding to map data at a reduced scale from the facility database , And those having a map and facility data display means for displaying by superimposing the map data read by the read facility data and map data reading means by facility data reading means.

As described above, the present invention is a facility database that stores facility data of a pipeline having a first coordinate based on a relative position relative to another facility and a second coordinate based on an absolute position, and two types of coordinates. Facility data display switching operation means for selecting one or both of them, a map database storing map data, a map data display switching operation means for specifying a range and scale of map data to be displayed, and this map data display switching operation means map data reading means for map data specified out look map database or Ra読 by, a facility data having the coordinates selected by the facility data display switching operation unit, the range specified by the map data display switching operation unit and facility data reading means reads the facility data corresponding to the map data scale from facility database, and facility Since with the map and facility data display means for displaying by superimposing the map data read by the read property data and the map data reading unit by chromatography data reading means, the two types of coordinates for a single facility data using either one or both coordinates, Ru can be displayed by superposing facility data on a map.
