[Description of the positioning system]
First, the configuration of the positioning system including the 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 GPS (Global Positioning System). The positioning system includes multiple positioning satellites 3 , multiple 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 its position. The positioning satellite 3 transmits a positioning signal indicating the position of the positioning satellite 3 and the transmission time, for example.

The reference station 4 is a device that receives a positioning signal transmitted by the positioning satellite 3 and outputs measurement information for the correction information generation system 6 to calculate correction information. The correction information is information used for correcting 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 pre-stored in the storage unit of the correction information generation system 6 .

A reference station 4 receives positioning signals from a plurality of positioning satellites 3 . The reference station 4 measures its position using known positioning methods. 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 transmission 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, reference station identification information (reference station ID (Identification)) for identifying the reference station and measurement information indicating the measured position (coordinates, etc.) of the reference station 4 to correction information by wireless or wired communication. Send to 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 supply of the reference station 4 can be shared with the power supply of the base station 7, so that the work of installing the reference station 4 can be efficiently proceeded.

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 . The correction information generating system 6 stores, for example, the installation position of each of the plurality of reference stations 4 in advance in the storage unit in association with the reference station ID of the reference station 4 . For example, in response to receiving the measurement information from the reference station 4, the correction information generation system 6 sets 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, 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. 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 generating system 6 transmits the generated correction information to the communication terminals 5 within a predetermined range with reference to the reference station 4, which is the transmission source of the measurement information, via the base station 7, for example.

The reference station 4 may function as a correction information generation system 6 . In this case, the reference station 4 generates the correction information described above 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 positioning signals transmitted by the positioning satellites 3 . The communication terminal 5 is, for example, a smart phone, a tablet terminal, a personal computer, an aircraft (drone), or the like. The communication terminal 5 has, for example, an antenna for receiving positioning signals and an antenna for receiving wireless communication signals.

A communication terminal 5 receives positioning signals from a plurality of positioning satellites 3 . Communication terminal 5 also receives correction information from correction information generation system 6 via 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 transmission source of the positioning signal received by the communication terminal 5 and the transmission time of the positioning signal. Then, the communication terminal 5 determines the position of the communication terminal 5 by correcting the calculated position using the correction information (for example, by adding or subtracting the error indicated by the correction information).

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

[Explanation of information processing system S]
Next, a configuration for the management server 1 to execute processing according to this embodiment will be described below. When the user wishes 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 reception unit 121 receives a display request for displaying the position of the reference station 4 from the display device 2 according to the user's operation.

The acquisition unit 122 acquires from the storage unit 11 reference station information regarding one or more reference stations 4 included in the positioning system 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 location of the reference station 4 . The location of the reference station 4 includes, for example, at least one of the assumed location of the reference station 4 and the actual location of the reference station 4 .

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 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 at which 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. If 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 locations described here, and may be installed at other installation locations.

When the reference station 4 is installed on a steel tower, work at a high place is required, so installation and maintenance tend to be more difficult than when the station is installed on the ground. Moreover, when the reference station 4 is installed on a building, it is necessary to negotiate with the owner of the building. As will be described later, the management server 1 makes it possible for the user to easily grasp the location where each reference station 4 is installed by enabling the installation location of each reference station 4 to be overlooked on the map.

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 installed. The assumed position and the actual position are represented by coordinates such as latitude and longitude, for example. The actual position may be blank if the position where the reference station 4 is actually installed is not fixed. In order for 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, since it is not always possible to place the reference station 4 at the assumed position due to the convenience of the site, etc., the reference station 4 may be installed at an actual position different from the assumed position.

The work status is the status of work for installing the reference station 4 . The work of installing the reference station 4 is, for example, the work of installing the reference station 4 in the base station 7 of wireless communication such as mobile communication. The work status is, for example, that the design for installing the standard station 4 is underway, that the construction for installing the standard station 4 is underway or has been completed, or that the acceptance inspection after the installation of the standard station 4 has been completed. 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 work status of each reference station 4 to be overlooked on a map.

The acquisition unit 122 also acquires from the storage unit 11 location information relating to one or a plurality of locations for storing articles for maintenance of the reference station 4 . The site information is information including, for example, a site ID for identifying a site, the position of the site, and the reference station IDs of one or more standard stations 4 that can be maintained using items stored at the site. .

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

FIGS. 5(a) and 5(b) are schematic diagrams for explaining how the determination unit 123 determines the reference station image. In FIG. 5A, the determination unit 123 determines a reference station image of a display mode corresponding to the work situation indicated by the reference station information. In the example of FIG. 5A, the determining unit 123 makes the reference station image in different colors according to the work situation. For example, the determination unit 123 determines whether the work status indicates that the installation of the reference station 4 has not been completed (during design or construction), or whether the work status indicates that the installation of the reference station 4 has been completed (construction completed). or accepted) is determined. As a result, the management server 1 can allow the user to easily grasp the work status of the reference station 4 from the reference station image.

In FIG. 5B, the determining unit 123 determines a reference station image of a display mode corresponding to the installation location indicated by the reference station information. In the example of FIG. 5(b), the determination unit 123 makes the reference station image have different patterns according to the work situation. For example, the determination unit 123 provides different displays when the installation location is on the ground, when the installation location is a steel tower, when the installation location is on a building, and when the installation location is undecided (blank). A reference station image of the aspect is determined. As a result, the management server 1 can allow the user to easily grasp the installation location of the reference station 4 from the reference station image.

It is desirable that the determination unit 123 determines the reference station image of the display mode corresponding to the installation location in addition to the work situation. That is, it is desirable that the determination unit 123 determines the reference station image of the display mode corresponding to the combination of the work situation and the installation location. For example, the determination unit 123 sets the reference station image to a color corresponding to the work situation illustrated in FIG. 5A, and sets the reference station image to a pattern corresponding to the installation location illustrated in FIG. 5B. As a result, the management server 1 can allow the user to grasp the work status and installation location of the reference station 4 at the same time from one reference station image.

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

When the reference station 4 is installed in the base station 7, the determination unit 123 selects the reference station in the display form corresponding to the type of the 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 be determined. In this case, the determining unit 123 identifies the type of the base station 7 based on the information about the base station 7 pre-stored in the storage unit 11 . The type of the base station 7 is represented, for example, by which mobile communication the base station 7 supports, 3G (Generation), 4G/LTE (Long Term Evolution), or 5G.

The determination unit 123 determines a reference station image of a different display mode depending on, for example, which of 3G, 4G/LTE, or 5G mobile communication the base station 7 in which the reference station 4 is installed corresponds to. As a result, the management server 1 can allow the user to simultaneously grasp the work status and type of the reference station 4 from 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 of a display mode corresponding to the work status of the reference station 4, the installation location, the type of the 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 is determined, and the assumed position in the case of the reference station 4 whose actual position is not determined. The display information may further include a base image of each of one or more bases and the 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 base images. The display device 2 displays a map (map image) of a predetermined range on the display unit. The display device 2 may display a map stored in advance in the storage unit 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 including 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 the user's operation.

The display device 2 displays the reference station image 21 of each 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 .

As a result, the user can easily grasp the work status and installation location of each of the one or more reference stations 4 as a distribution on the map, so that the work of installing the reference stations 4 can be performed smoothly. In addition, on the same map, the user can easily grasp the position of one or a plurality of bases for storing articles for maintenance of the reference station 4 in addition to the position of the reference station 4. Therefore, the user maintains the reference station 4. Work can be done smoothly.

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

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

The determination unit 123 also determines 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 with respect to the position of the selected reference station 4, for example. . In this case, the determining unit 123, for example, determines 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. , is calculated as the number of other stations.

Further, the determination unit 123 determines a site having a predetermined relationship with the selected reference station 4 from among one or more sites. For example, based on the site information, the determination unit 123 determines the site closest to the position of the selected reference station 4 among one or more sites as a site having a predetermined relationship with the selected reference station 4. good too. Further, for example, based on the site information, the determining unit 123 determines, from among the one or a plurality of sites, the site storing the article for maintenance of the selected standard station 4 and the selected standard station 4. You may determine as a base in a relationship.

The determination 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, and the determined amount of deviation, link information, and the number of other stations. The detailed information may further include information indicating the site associated with the selected reference station 4, determined by the determination unit 123. FIG.

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

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

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

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

Further, 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 of the reference station 4 and the actual position, the user performs a predetermined operation using the display device 2 . In the management server 1, the reception unit 121 receives a display request for displaying the difference between the assumed position and the actual position of the reference station 4 from the display device 2 in accordance with the 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 assumed and actual positions of each reference station 4 .

Show your location on the map and on. The image showing the actual position of the reference station 4 is, for example, the reference station image 21 described above. The image indicating the assumed position of the reference station 4 is, for example, the predetermined icon image 24 . This allows the user to easily grasp the difference between the initially assumed positions of the plurality of reference stations 4 and the actual positions.

In addition, the management server 1 may display the number of reference stations 4 positioned within a predetermined figure on the map on the display device 2 . When the user wishes to calculate the number of reference stations 4 located within a figure of a predetermined shape on the map, the user uses the display device 2 to perform an operation of designating a figure for calculating the number of reference stations 4 (for example, map above). In the management server 1 , the reception unit 121 receives from the display device 2 information indicating a figure (for example, the position and radius of a circle) specified by the user.

The acquisition unit 122 acquires reference station information of one or more reference stations 4 from the storage unit 11 . The determination unit 123 determines the number of stations, which is the number of one or more reference stations 4 positioned within the graphic designated by the user. The determination unit 123 calculates, as the number of stations, the number of reference stations 4 whose positions on the map corresponding to the positions of the reference stations 4 are included in the figure specified by the user.

The display control unit 124 causes the graphic designated by the user to be displayed on the map, and causes the display device 2 to display the number of stations determined by the determination unit 123 .

This allows the user to easily determine whether or not a sufficient number of reference stations 4 are installed within the specified figure.

Furthermore, the management server 1 may display, on the display device 2, areas in which the measurement information output by the reference station 4 is frequently used on a map. A user performs a predetermined operation using the display device 2 when the user desires to display an area in which the measurement information output by the reference station 4 is frequently used. In the management server 1, the reception unit 121 receives from the display device 2 a display request for displaying the frequently used area of the measurement information output by the reference station 4 in accordance with the user's operation.

The acquisition unit 122 acquires the usage status corresponding to the number of times the measurement information output from the reference station 4 has been used. The usage status is, for example, the number of times correction information generated based on measurement information output from the reference station 4 has been transmitted to one or more communication terminals 5 . For example, the acquisition unit 122 receives the usage status from the correction information generation system 6 or acquires the usage status stored in advance in the storage unit 11 .

For example, the determination unit 123 determines whether or not the usage status acquired by the acquisition unit 122 satisfies a predetermined condition (such as being equal to or greater than a predetermined threshold value) for each of one or more reference stations 4 . For example, the determination unit 123 selects an area of a predetermined size (a circle having a predetermined radius centered on the reference station 4, etc.) on the map displayed on the display device 2 with reference to the reference station 4 that satisfies the usage conditions. , is determined as an area that satisfies the usage conditions.

The display control unit 124 causes the display device 2 to display, in addition to the reference station image, an area on the map where the usage condition satisfies the condition in a display mode different from other areas on the map. The display control unit 124, for example, transmits to the display device 2 display information indicating an area whose usage status satisfies the condition.

According to the display information transmitted by the management server 1, the display device 2 displays the areas on the map whose usage conditions satisfy the condition in a display mode (color, pattern, etc.) different from other areas on the map. As a result, the user can easily grasp the area around the reference station 4 that is frequently used, for example, on the map, and can reflect it in the installation plan of the reference station 4 .
