[Configuration of management server 1]
FIG. 2 is a block diagram of the management server 1 according to this embodiment. In FIG. 2, arrows indicate main data flows, and data flows other than those shown in FIG. 2 may exist. In FIG. 2, each block shows the configuration of a functional unit rather than a hardware (device) unit. Therefore, the blocks shown in FIG. 2 may be implemented within a single device, or may be implemented separately within multiple devices. Data may be exchanged between blocks via any means such as a data bus, network, or portable storage medium.

The management server 1 includes a storage section 11 and a control section 12. The storage unit 11 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, and the like. The storage unit 11 stores in advance a program to be executed by the control unit 12. Furthermore, the storage unit 11 stores reference station information regarding the reference station 4 in advance. Furthermore, the storage unit 11 stores in advance base information regarding bases for storing items for maintaining the reference station 4. The storage unit 11 may be provided outside the management server 1, and in that case, data may be exchanged with the control unit 12 via a network.

Processes performed by each of the reception unit 121, acquisition unit 122, determination unit 123, and display control unit 124 will be described later.

[Description of positioning system]
First, the configuration of a positioning system including a reference station 4 whose information is managed by the management server 1 will be described below. FIG. 3 is a schematic diagram of the positioning system according to this embodiment. The positioning system is, for example, a GNSS such as a Quasi-Zenith Satellite System (QZSS) or a Global Positioning System (GPS). The positioning system includes a plurality of positioning satellites 3, a plurality of reference stations 4, and a correction information generation system 6.

The positioning satellite 3 is an artificial satellite placed in outer space that transmits a positioning signal used by the communication terminal 5 to measure the position. The positioning satellite 3 transmits, for example, a positioning signal indicating the position of the positioning satellite 3 and the transmission time.

The reference station 4 is a device that outputs measurement information for the correction information generation system 6 to calculate correction information by receiving the positioning signal transmitted by the positioning satellite 3. The correction information is information used to correct the position measured by the communication terminal 5 based on the positioning signal. The reference station 4 is installed at a known position on the ground, for example, and has an antenna for receiving positioning signals. The positions of the plurality of reference stations 4 are stored in advance in the storage unit of the correction information generation system 6.

The reference station 4 receives positioning signals from a plurality of positioning satellites 3. The reference station 4 measures the position of the reference station 4 using a known positioning method. The reference station 4 calculates the position of the reference station 4 using, for example, the position of the positioning satellite 3 that is the source of the positioning signal received by the reference station 4 and the transmission time of the positioning signal. The reference station 4 transmits, for example, measurement information indicating reference station identification information (reference station ID (Identification)) for identifying the reference station and the measured position (coordinates, etc.) of the reference station 4 to correction information by wireless communication or wired communication. It is transmitted to the generation system 6.

The reference station 4 may be installed on a base station 7 that transmits and receives signals for wireless communication such as mobile communication performed by the communication terminal 5. As a result, the user does not need to secure a site for installing the reference station 4, and the power source of the reference station 4 can be shared with the power source of the base station 7, so that the work of installing the reference station 4 can proceed efficiently.

The correction information generation system 6 is a system that generates correction information for correcting the position measured by the communication terminal 5 based on the measurement information output by the reference station 4. For example, the correction information generation system 6 stores in advance the installation position of each of the plurality of reference stations 4 in association with the reference station ID of the reference station 4 in the storage unit. For example, in response to receiving measurement information from the reference station 4, the correction information generation system 6 determines the position of the reference station 4 indicated by the measurement information and the installation position of the reference station 4 associated with the reference station ID indicated by the measurement information. Based on this, correction information is generated.

The correction information generation system 6 generates correction information that indicates, as an error, the difference between the position of the reference station 4 indicated by the measurement information and the installation position of the reference station 4 associated with the reference station ID indicated by the measurement information, for example. The correction information is not limited to the specific information described here, and may indicate other information that can be used to correct the position of the communication terminal 5. The correction information generation system 6 transmits the generated correction information, for example, via the base station 7 to the communication terminals 5 within a predetermined range with reference to the reference station 4 that is the transmission source of the measurement information.

The reference station 4 may function as a correction information generation system 6. In this case, the reference station 4 generates the above-mentioned correction information based on the positioning signal received from the positioning satellite 3 and transmits it to the communication terminal 5.

The communication terminal 5 is a computer that performs wireless communication with other devices and measures the position of the communication terminal 5 based on the positioning signal transmitted by the positioning satellite 3. The communication terminal 5 is, for example, a smartphone, a tablet terminal, a personal computer, a flying object (drone), or the like. The communication terminal 5 includes, for example, an antenna for receiving positioning signals and an antenna for receiving wireless communication signals.

The communication terminal 5 receives positioning signals from the plurality of positioning satellites 3. Furthermore, the communication terminal 5 receives correction information from the correction information generation system 6 via the base station 7 . The communication terminal 5 measures the position of the communication terminal 5 using a known positioning method. The communication terminal 5 calculates the position of the communication terminal 5 using, for example, the position of the positioning satellite 3 that is the source of the positioning signal received by the communication terminal 5 and the transmission time of the positioning signal. The communication terminal 5 then determines the position of the communication terminal 5 by correcting the calculated position using the correction information (for example, by adding or subtracting an error indicated by the correction information).

The management server 1 is not limited to the specific positioning system described here, and may manage information regarding other positioning systems including the reference station 4 for correcting the position measured by the communication terminal 5.

[Description of information processing system S]
Next, the configuration for the management server 1 to execute the processing according to this embodiment will be described below. When the user desires to display the position of the reference station 4, the user performs a predetermined operation using the display device 2. In the management server 1, the receiving unit 121 receives a display request for displaying the position of the reference station 4 from the display device 2 in response to a user's operation.

The acquisition unit 122 acquires reference station information regarding one or more reference stations 4 included in the positioning system from the storage unit 11 in response to the reception unit 121 accepting the display request. The reference station information includes the work status of the work to install the reference station 4 and the position of the reference station 4. The position of the reference station 4 includes, for example, at least one of a position where the reference station 4 is assumed to be installed and a position where the reference station 4 is actually installed.

FIG. 4 is a schematic diagram of exemplary reference station information. The reference station information includes, for example, the reference station ID for identifying the reference station 4, the name of the reference station 4 (station name in FIG. 4), the installation location of the reference station 4, the assumed position of the reference station 4, and the reference station 4. This information includes the actual position of the reference station 4 and the work status of the work to install the reference station 4 (status in FIG. 4).

The installation location of the reference station 4 is the location where the reference station 4 is actually installed (coordinates, etc.). The installation location is, for example, on the ground, on a steel tower, or on a building. When the installation location is on the ground, the reference station 4 is installed directly on the ground. When the installation location is a steel tower, the reference station 4 is installed on the steel tower. When the installation location is on a building, the reference station 4 is installed on the roof of a building such as a building. The installation location may be left blank if the location where the reference station 4 is actually installed has not been determined. The reference station 4 is not limited to the specific installation location described here, but may be installed at other installation locations.

When the reference station 4 is installed on a steel tower, work at a height is required, so installation and maintenance tend to be more difficult than when it is installed on the ground. Furthermore, when the reference station 4 is installed on a building, negotiations with the building owner are required, so installation and maintenance tend to take more time and cost than when it is installed on the ground. As will be described later, the management server 1 allows the user to easily understand the location where each reference station 4 is installed by allowing the user to view the location where each reference station 4 is installed.

The assumed position of the reference station 4 is a position where the reference station 4 is assumed to be installed. The actual position of the reference station 4 is the position where the reference station 4 is actually installed or has been installed. The assumed position and the actual position are represented by coordinates such as latitude and longitude, for example. The actual position may be left blank if the actual location of the reference station 4 has not been determined. In order to enable the positioning system to perform highly accurate positioning in various areas, it is assumed that the plurality of reference stations 4 are evenly arranged at predetermined intervals. The position of the reference station 4 assumed in the positioning system in this way is called an assumed position. On the other hand, the reference station 4 may not always be placed at the assumed position due to site constraints, and therefore the reference station 4 may be installed at an actual position different from the assumed position.

The work status is the status of work to install the reference station 4. The work of installing the reference station 4 is, for example, the work of installing the reference station 4 at a base station 7 for wireless communication such as mobile communication. The work status includes, for example, that the design for installing the reference station 4 is being carried out, that the construction for installing the reference station 4 is being performed or has been completed, and that the acceptance inspection after installing the reference station 4 has been completed. Including etc. As will be described later, the management server 1 allows the user to easily grasp the work status of a plurality of reference stations 4 by allowing the user to view the work status of each reference station 4 from above on a map.

The acquisition unit 122 also acquires base information regarding one or more bases for storing items for maintaining the reference station 4 from the storage unit 11 . The base information is, for example, information including a base ID for identifying the base, the location of the base, and the reference station ID of one or more reference stations 4 that can be maintained with the items stored at the base. .

The determining unit 123 determines a reference station image to be displayed on the display device 2 for each of the plurality of reference stations 4 based on the reference station information acquired by the acquiring unit 122. The reference station image is an image such as an icon in a display mode corresponding to the content of the reference station information of each reference station 4.

FIGS. 5A and 5B are schematic diagrams for explaining a method by which the determining unit 123 determines a reference station image. In FIG. 5A, the determining unit 123 determines a reference station image in a display mode corresponding to the work situation indicated by the reference station information. In the example of FIG. 5A, the determining unit 123 colors the reference station image in different colors depending on the work situation. For example, the determining unit 123 determines whether the work status indicates that the installation of the reference station 4 has not been completed (under design or under construction) or when the work status indicates that the installation of the reference station 4 has been completed (under construction). A reference station image with a different display mode is determined depending on whether the reference station image is displayed (or has been inspected). Thereby, the management server 1 allows the user to easily understand the working status of the reference station 4 using the reference station image.

In FIG. 5B, the determining unit 123 determines a reference station image in a display mode corresponding to the installation location indicated by the reference station information. In the example of FIG. 5(b), the determining unit 123 makes the reference station image have different patterns depending on the work situation. For example, the determining unit 123 displays different displays depending on whether the installation location is on the ground, on a steel tower, on a building, or when the installation location is undetermined (blank). Determine the reference station image of the aspect. Thereby, the management server 1 can make the user easily understand the installation location of the reference station 4 using the reference station image.

It is desirable that the determining unit 123 determines a reference station image in a display mode corresponding to the installation location in addition to the work situation. That is, it is preferable that the determining unit 123 determines a reference station image in a display mode that corresponds to the combination of work situation and installation location. For example, the determining unit 123 colors the reference station image in a color corresponding to the work situation illustrated in FIG. 5(a), and makes the reference station image in a pattern corresponding to the installation location illustrated in FIG. 5(b). Thereby, the management server 1 can allow the user to simultaneously grasp the working status and installation location of the reference station 4 using one reference station image.

Further, for example, when the work status indicates that the installation of the reference station 4 is not completed, the determining unit 123 determines a common reference station image regardless of the installation location, and when the work status indicates that the installation of the reference station 4 is not completed. In the case of indicating that the reference station is installed, a reference station image with a display mode corresponding to the installation location may be determined.

When the reference station 4 is installed at the base station 7, the determining unit 123 selects the reference station in a display mode corresponding to the type of base station 7 where the reference station 4 is installed, in addition to the work situation (or work situation and installation location). An image may also be determined. In this case, the determining unit 123 identifies the type of the base station 7 based on information regarding the base station 7 stored in the storage unit 11 in advance. The type of base station 7 is represented by, for example, whether the base station 7 supports mobile communication among 3G (Generation), 4G/LTE (Long Term Evolution), or 5G.

The determining unit 123 determines reference station images with different display modes depending on, for example, whether the base station 7 where the reference station 4 is installed supports mobile communication among 3G, 4G/LTE, or 5G. Thereby, the management server 1 can allow the user to simultaneously grasp the working status and type of the reference station 4 using the reference station image.

The display control unit 124 causes the display device 2 to display the reference station image determined by the determination unit 123 at a position on the map corresponding to the position of the reference station 4 . The reference station image is an image in a display mode corresponding to the working status of the reference station 4, the installation location, the type of base station 7 in which the reference station 4 is installed, etc., as described above. The display control unit 124 transmits display information including, for example, a reference station image of each of one or more reference stations 4 and the position of the reference station 4 to the display device 2. The position of the reference station 4 is, for example, the actual position in the case of the reference station 4 whose actual position has been determined, and the assumed position in the case of the reference station 4 whose actual position has not been determined. The display information may further include a base image of each of one or more bases and a position of the base. The base image is, for example, an image such as a predetermined icon.

FIG. 6 is a schematic diagram of a screen on which the display device 2 displays a reference station image and a base image. The display device 2 displays a map (map image) of a predetermined range on a display section. The display device 2 may display a map stored in advance in the storage section of the display device 2, or may display a map received from the management server 1 or another server. The range of the map displayed by the display device 2 is, for example, a range that includes at least the positions of all the one or more reference stations 4 indicated by the display information transmitted by the management server 1. The range of the map displayed by the display device 2 may be changed according to a user's operation.

The display device 2 displays each reference station image 21 of one or more reference stations 4 at a position on the map corresponding to the position of the reference station 4, according to the display information transmitted by the management server 1. Further, the display device 2 displays the base image 22 of each of one or more bases at a position on the map corresponding to the position of the base, according to the display information transmitted by the management server 1.

Thereby, the user can easily grasp the working status and installation location of each of the one or more reference stations 4 as a distribution on a map, and therefore can smoothly perform the work of installing the reference stations 4. In addition, the user can easily grasp the location of one or more bases for storing items for maintaining the reference station 4 in addition to the location of the reference station 4 on the same map. Work can also be done smoothly.

Further, the management server 1 may display detailed information of the reference station 4 on the map on the display device 2. When the user desires to display detailed information about the reference station 4, the user uses the display device 2 to perform an operation to select the reference station image 21 of the reference station 4 to be displayed. In the management server 1 , the reception unit 121 receives from the display device 2 information indicating the reference station 4 selected by the user from among the one or more reference stations 4 displayed on the display device 2 and whose detailed information is to be displayed. accept.

The acquisition unit 122 acquires base station information of one or more base stations 4 and base information of one or more bases from the storage unit 11 . The determining unit 123 generates detailed information based on the reference station information of one or more reference stations 4 acquired by the acquiring unit 122. The determining unit 123 determines, for example, the amount of deviation between the assumed position and the actual position of the selected reference station 4. In this case, the determining unit 123 calculates, for example, the distance between the assumed position and the actual position of the reference station 4 as the amount of deviation. Further, the determining unit 123 determines link information such as a URI (Uniform Resource Identifier) for accessing external information (detailed map, etc.) regarding the selected reference station 4, for example.

Further, the determining unit 123 determines, for example, the number of other stations, which is the number of one or more reference stations 4 different from the selected reference station 4, which are located within a predetermined range based on the position of the selected reference station 4. . In this case, the determining unit 123 determines, for example, the number of reference stations 4 other than the selected reference station 4 located within a circle with a predetermined radius (such as a circle with a radius of 250 km) centered on the position of the selected reference station 4. , calculated as the number of other stations.

Further, the determining unit 123 determines a base that has a predetermined relationship with the selected reference station 4 from among the one or more bases. For example, the determining unit 123 determines the base closest to the position of the selected reference station 4 among the one or more bases as the base having a predetermined relationship with the selected reference station 4, based on the base information. Good too. Further, for example, based on the base information, the determining unit 123 selects a base that stores items for maintaining the selected reference station 4 from among one or more bases, and selects a base that stores items for maintaining the selected reference station 4 and a predetermined number of bases. It may also be determined as a related base.

The determining unit 123 generates detailed information including, for example, the name, installation location, and work status indicated by the reference station information of the selected reference station 4, the determined deviation amount, link information, and the number of other stations. The detailed information may further include information indicating a base related to the selected reference station 4 determined by the determining unit 123.

The display control unit 124 causes the display device 2 to display detailed information of the reference station 4 selected by the user. For example, the display control unit 124 transmits the detailed information generated by the determination unit 123 to the display device 2.

FIG. 7 is a schematic diagram of a screen on which the display device 2 displays detailed information of the selected reference station 4. The display device 2 displays the detailed information 23 transmitted by the management server 1 on a map in association with the reference station image 21 of the selected reference station 4.

By looking at the amount of deviation included in the detailed information, the user can quantitatively grasp the difference between the originally assumed position and the actual position of the reference station 4. Furthermore, by looking at the number of other stations included in the detailed information, the user can easily determine whether or not a sufficient number of reference stations 4 are installed around the selected reference station 4. Further, by selecting the link information, the user can easily access information regarding the selected reference station 4.

Further, the display device 2 displays the base image 22 of the base related to the selected reference station 4 in a different display mode from the base images of other bases, according to the detailed information transmitted by the management server 1. In the example of FIG. 7, the display device 2 displays the reference station image 21 of the selected reference station 4 and the base image 22 of the base related to the selected reference station 4, connected by a broken line. Thereby, the user can easily grasp the location of the base related to the selected reference station 4 on the map.

Furthermore, the management server 1 may display the difference between the assumed position and the actual position of the reference station 4 on the map on the display device 2. When the user desires to display the difference between the assumed position and the actual position of the reference station 4, the user performs a predetermined operation using the display device 2. In the management server 1, the receiving unit 121 receives a display request from the display device 2 to display the difference between the assumed position and the actual position of the reference station 4 in response to a user's operation.

The acquisition unit 122 acquires reference station information of one or more reference stations 4 from the storage unit 11 . The reference station information includes the assumed position and actual position of each reference station 4.

Display the position and . The display control unit 124 transmits display information including, for example, a reference station image of one or more reference stations 4 , an assumed position of the reference station 4 , and an actual position of the reference station 4 to the display device 2 . The display information may not include the actual position of the reference station 4 whose actual position has not been determined.
