Description

Technical Field

[0001] One embodiment of the present invention generally relates to a route editing support device for editing a route.

Background Art

[0002] Vessels (e.g., ships, submarines, boats, etc.) are obliged to carry nautical charts and nautical publications for planning and displaying the navigation routes of the vessels during navigation. Therefore, an information system such as an Electronic Chart Display and Information System (ECDIS) is installed. The ECDIS software-processes electronic chart data to display a chart of a desired sea area. The ECDIS may be configured to display a route for route monitoring while the vessel is navigating on the route. In some cases, it is necessary to edit the monitored route. For example, with respect to an obstacle in the monitored route, it is necessary to deviate from the route to avoid a collision.

[0003] With the progress of navigation systems, various navigation route editing technologies (e.g., instant track technology) have been introduced. Currently, the instant track technology provides a temporary tracking consisting of four waypoints to return to / or deviate from the monitored route. The instant track technology can create a new route for the vessel to return to the route when it goes outside the waterway limit and / or to temporarily deviate from the monitored route when facing an obstacle.

[0004] However, the instant track technology has limitations such as distance limitations. For example, the destination point needs to be within 50 miles from the vessel. Furthermore, since there is a time lag at the start of route editing in the instant track technology, some user operations are required before creating a new route. Furthermore, the instant track technology does not provide the display of both the monitored route and the newly created route. As a result, the newly created route cannot be compared with the monitored route, and the user cannot make further decisions when editing the route.

[Modes for carrying out the invention]

[0026] In the following description, numerous specific embodiments are described in order to provide a sufficient disclosure. However, it will be apparent to those skilled in the art that this disclosure is sufficient for carrying out the invention even without these specific embodiments. Apparatuses and the like are shown using block diagrams or the like to avoid obscuring this disclosure.

[0027] Some embodiments of this disclosure are described below with reference to the drawings. The drawings show some, but not all, embodiments of this disclosure. In fact, various embodiments of this disclosure can be carried out in many different forms and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are described in order to satisfy the requirements to which this disclosure is applicable. Reference numerals refer to the same elements throughout.

Accordingly, such terms should not be construed as limiting the scope of embodiments of the present invention.

[0028] Embodiments are described herein for illustrative purposes and include many variations. Various omissions and substitutions of equivalents are included in embodiments that do not depart from the scope of this disclosure. Furthermore, terms used herein are for illustrative purposes only and are not necessarily limited to the meanings described herein. Headings used herein are for convenience only and have no legal or restrictive effect.

[0029] Terms such as “for example,” “like,” “have,” and “include,” as used herein and in the claims, and other forms thereof, when used in conjunction with a list of one or more components or other items, shall be interpreted as open-ended, meaning that the list shall not be deemed to exclude any other additional components or items.

[0030] One of the objectives of the present invention is to provide efficient route editing operations. Another objective of the present invention is to display the first route and the second route simultaneously on the display of the route planning device. Conning Information and the second route Conning The objective is to generate information. According to various embodiments, the present invention proposes a route editing support device. The route editing support device enables a user to edit a first route to form a second route. The route editing support device requires only a single user operation to initiate editing of the first route. This minimizes the time lag at the start of route editing.

[0031] The route editing support device is configured to accept the positions of a first set of waypoints defining a first route and a second set of waypoints defining a second route. The route editing support device is further configured to generate display data for simultaneously displaying the first and second routes on the display. By simultaneously displaying the first and second routes, the user can access both the original route (i.e., the first route) and the edited route (the second route), and easily compare the routes, navigation parameters, and navigation courses of the first and second routes. This allows for more appropriate navigation decisions when encountering obstacles in the set route (such as the first route) due to moving objects (such as ships on water or aircraft in the air), or when a new route (such as the second route) or a portion of a route needs to be generated. Furthermore, new routes can be easily generated using the route editing support device by editing the set route or a segment of the set route. Simultaneous display of both routes also allows for comparison between the original route and the edited route. Additionally, the route editing support device allows the user to edit routes of any distance. In other words, users can edit routes without distance limitations.

[0032] Furthermore, the route editing support device generates coning information for the first route and coning information for the second route, which are displayed on the screen. The route editing support device simultaneously displays the first route, its coning information, the second route, and its coning information on the screen. By simultaneously displaying both routes and their respective coning information, the user can compare the two routes based on the coning information, which includes multiple navigation-related parameters associated with each route, and select either the first or second route for navigation.

[0033] Figure 1 is a schematic diagram illustrating the working environment 100a of the route editing support device 101 according to an exemplary embodiment. In the exemplary embodiment, the route editing support device 101 is installed on a vessel navigating on water. The water can include seas, oceans, rivers, etc. In some embodiments, the route editing support device 101 may be installed on an aircraft. The route editing support device 101 can receive input from a user 105, which may include location information indicating the location of the departure point, the location of the destination, the location of the first waypoint group, and the location information indicating the location of the second waypoint group. The location / position information may include location data such as longitude or latitude, direction data, GPS coordinates, distance from a point, etc. The route editing support device 101 is communicably connected to a user terminal 103 and a database 109 via a network 107.

[0034] The user terminal 103 includes an application 103b installed thereon, which displays different navigation-related information for the user 105 operating the user terminal 103. The user terminal 103 may be any user-accessible device such as a smartphone, portable computer, or display unit. In an exemplary embodiment, the user terminal 103 may include an electronic chart display device (ECDIS). The user terminal 103 uses the application 103b to display different navigation information, such as charts and currents, on the display screen of the user terminal 103. In an exemplary embodiment, the user terminal 103 may be configured as a touchscreen display.

[0035] Furthermore, database 109 can store updated nautical charts, the latest information on weather forecasts, information on currents, and nautical charts that can be used by ships to navigate the water. Database 109 may also include information on hazardous locations underwater, such as the locations of eddies and obstacles. Database 109 can include navigation data such as information on salinity, water temperature and air temperature, atmospheric pressure and wind (speed, gusts, direction), and the geographical location of ships, including their longitude and latitude. Database 109 may also include updated nautical charts and the latest information on weather forecasts that can be used by ships.

[0036] In an alternative embodiment, the database 109 may be embodied as a map database, or it may be a compiled navigation database that can be used in or with the user terminal 103 to provide navigation and / or map-related functions to the user 105. In such a case, the database 109 can be downloaded to or stored in the user terminal 103.

[0037] Network 107 may include appropriate logic, circuitry, and interfaces that can be configured to provide multiple network ports and multiple communication channels for sending and receiving data, such as selected locations including a origin and destination. Each network port may correspond to a virtual address (or physical machine address) for sending and receiving communication data. For example, the virtual address may be an Internet Protocol version 4 (IPv4) (or IPv6) address, and the physical address may be a MAC address. Network 107 may be associated with an application layer for implementing a communication protocol based on one or more communication requests from at least one of one or more communication devices. Communication data can be sent and received via the communication protocol. Examples of such wired and wireless communication protocols include, but are not limited to, Transmission Control Protocol and Internet Protocol (TCP / IP), User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), ZigBee, EDGE, Infrared (IR), IEEE 802.11, 802.16, Cellular Communication Protocol, and / or Bluetooth® (BT) Communication Protocol.

[0038] Examples of network 107 may include, but are not limited to, wireless channels, wired channels, or combinations of wireless and wired channels. Wireless or wired channels may be associated with network standards that can be defined by one of the following: Local Area Network (LAN), Personal Area Network (PAN), Wireless Local Area Network (WLAN), Wireless Sensor Network (WSN), Wireless Area Network (WAN), Wireless Wide Area Network (WWAN), Long-Term Evolution (LTE) network, Public Telephone Services (POTS), and Metropolitan Area Network (MAN). Furthermore, wired channels may be selected based on bandwidth criteria. For example, fiber optic channels can be used for high-bandwidth communications. Additionally, coaxial cable-based or Ethernet-based communication channels may be used for moderate-bandwidth communications.

[0039] Some embodiments are based on the recognition that, in order to perform efficient route editing, multiple routes should be displayed simultaneously so that users can compare routes, edit them, and select the best route.

[0040] To this end, the route editing support device 101 enables the user 105 to edit a first route consisting of a first group of waypoints. The route editing support device 101 is configured to receive position information indicating the location of a second group of waypoints. The second group of waypoints defines a second route. The route editing support device 101 is further configured to generate display data for simultaneously displaying the first and second routes on the display. The route editing support device 101 also generates coning information for the first route and coning information for the second route to be displayed on the display. A detailed analysis of the proposed route editing support device 101 is described below with reference to Figure 2.

[0041] Figure 2 shows a block diagram 100b of the route editing support device 101 illustrated in Figure 1, according to an exemplary embodiment. The route editing support device 101 includes a processing circuit configured to execute stored instructions and a memory 111 that stores instructions executable by the processing circuit. The memory 111 further includes a first route, the first route Conning Information, second route, and second route Conning It is configured to store navigation charts containing information. Memory 111 may include random access memory (RAM), read-only memory (ROM), flash memory, or any other suitable memory system.

[0042] In one embodiment, the route editing support device 101 includes an input unit 119, an editing reception unit 121, and a display data generation unit 123. The input unit 119 is configured to receive position information indicating the location of a first waypoint group representing a first route. The editing reception unit 121 is configured to receive position information indicating the location of a second waypoint group that defines a second route. The display data generation unit 123 generates display data for simultaneously displaying the first route and the second route. The display data generation unit 123 further generates the first route Conning Information and the second route Conning It is configured to generate information.

[0043] The route editing support device 101 also includes a display unit 113. The display unit 113 is configured to display a nautical chart. The route editing support device 101 further includes a touch panel 115 configured to receive multiple inputs from the user. For example, different position data may include position information indicating the positions of a first waypoint group, position information indicating the positions of a second waypoint group, position displacement information, etc. In some embodiments, the display unit 113 may be a touchscreen display panel configured to receive at least one of the following: position information indicating the positions of a first waypoint group, position information indicating the positions of a second waypoint group, position displacement information, etc. In addition, or alternatively, the route editing support device 101 may include an ECDIS. The memory 111, display 113 and touch panel 115 are connected via a bus 117 to an input unit 119, an editing reception unit 121 and a display data generation unit 123.

[0044] Location information indicating the positions of the first waypoint group and location information indicating the positions of the second waypoint group can be entered on the nautical chart displayed on the display unit 113 by the user 105 directly tapping a specific location, moving a cursor on the display unit 113, or entering the longitude and latitude of the first and second waypoint groups. In another embodiment, the user 105 can remotely input the positions of the first and second waypoint groups on the map displayed on the touchscreen of the user terminal 103 via the network 107 by operating the user terminal 103.

[0045] Therefore, user 105 can input different location data via the display unit 113 of the route editing support device 101 or the user terminal 103. In either case, the user interface shown to user 105 for receiving different location data remains the same. Figures 3 to 5 below provide a detailed description of the user interface used to receive different location data from user 105 via the display unit 113 or the user terminal 103.

[0046] Figure 3 shows a user interface 200a for accepting a first group of waypoints, 201a, 201b, 201c, 201d, and 201e, on a nautical chart 205, according to an exemplary embodiment. The user interface 200a shows the nautical chart 205. User 105 can input the first group of waypoints, each consisting of waypoints 201a, 201b, 201c, 201d, and 201e, by tapping a specific location on the nautical chart 205 or by entering latitude and longitude. In one embodiment, the first waypoint 201a and the last waypoint 201e are considered to be the origin and destination. Alternatively, in some embodiments, user 105 may first input a departure point 201a and a destination 201e, and then input waypoints 201b-201d between the departure point 201a and the destination 201e to form a first waypoint group of waypoints 201a, 201b, 201c, 201d, and 201e.

[0047] The first group of waypoints 201a-201e defines the first route 203. According to one embodiment, the first route 203 is editable by user 105. As used herein, “editing” means changing waypoints on the route to define a new route that a moving object planned to travel along the first route 203 can follow. To this end, the first route 203 forms the monitored route initially planned by the user. However, under certain circumstances, the user may want to change the section defined by the monitored route. These circumstances include the detection of obstacles on the first route 203, the occurrence of natural disasters, and user preferences. The first route 203 can be edited while navigating on the first route 203 or before commencing a voyage on the first route 203. For example, user 105 may discover an obstacle on the first route 203 while traveling along it. In such a case, user 105 can edit the first route 203 to avoid a collision with the obstacle. In another example, before commencing a voyage, Route 203 1 can be edited as part of the route plan for the voyage.

[0048] Figure 4 shows a user interface 200b for editing the first route 203 according to an exemplary embodiment. The user interface 200b includes an edit menu 211a, which implements an edit reception unit 121. User 105 can edit the first route 203 by tapping the edit menu 211a. In response to the tap on the edit menu 211a, the edit reception unit 121 creates a copy of the first route 203. Furthermore, user 105 may move the position of the copy of the first route 203 by dragging and dropping the copy of the first route 203 to a new position on the chart 205 on the display unit 113 that displays the chart 205, thereby forming the second route 209. The second route 209 is defined by the new position; that is, the waypoints of the second route are defined by the positions of the points at the new position. For example, the second route 209 is defined by a second set of waypoints 207a, 207b, and 207c located in new positions. In other words, a copy of the first route 203 corresponds to the second route 209 when the position of the copy of the first route 203 is displaced by dragging the copy of the first route 203 to a desired position on the display 113 in order to define the second route 209.

[0049] Alternatively, in some embodiments, user 105 can edit the first route 203 by dragging points of the first route 203 to desired waypoints on the display unit 113. For example, user 105 can drag waypoint 201b to waypoint 207a. Similarly, user 105 can input waypoints 207b, 207c. Waypoints 207a-207c may be referred to as a second set of waypoints. The second group of waypoints 207a-207c defines the second route 209. In some alternative embodiments, user 105 can input the second group of waypoints 207a-207c by inputting the latitude and longitude of each waypoint in the second group of waypoints 207a-207c to form the second route 209.

[0050] Furthermore, in some embodiments, an editing window 211b can be displayed while editing the first route 203. The editing window 211b includes tools such as "List", "On-chart edit", "Reverse", "Clear", "Monitor", "Linked User Chart", "Revert To Saved", "Undo", "Redo", "Close", "Save", and "Save as", which can help user 105 format and edit the first route 203. For example, user 105 can tap "Linked User Chart" to display all monitored routes (e.g., the first route 203). User 105 can tap the "Undo" tool to discard the last changes applied to Route 1 203 while editing it. Additionally, User 105 can tap the "Save" tool to save Route 2 209.

[0051] Furthermore, or alternatively, according to some embodiments, segments of the first route 203 can be edited. For that purpose, one or more waypoints from the first set of waypoints 201a-201e can be selected. A copy of the segment (i.e., one or more selected waypoints) can be created as a route that can be further displaced on chart 205 to obtain a new route while displaying the first route 203. Details of selecting segments of the first route 203 to obtain a new route are described below with reference to Figure 5.

[0052] Figure 5 shows a user interface 200c for editing a segment of the first route 203 according to an exemplary embodiment. In Figure 5, a portion of the first route 203 is shown for ease of explanation. The first route 203 may be segmented based on a first waypoint group 201a-201d. For example, the first route 203 includes segment 217 bounded by waypoints 201b and 201c, and segment 219 bounded by waypoints 201c and 201d. User 105 can edit any segment of the first route 203 by tapping the edit menu 211a. Alternatively, user 105 can select a segment to edit. For example, user 105 can select segment 219. In response to the selection of segment 219, the edit reception unit 121 creates a copy of segment 219. Furthermore, user 105 can input waypoints 213a, 213b, 213c, 213d, 213e, and 213f for editing segment 219. Waypoints 213a–213f may be called a second set of waypoints. Waypoints 213a–213f define a second route 215 that serves as an alternative route corresponding to segment 219.

[0053] Furthermore, in some embodiments, user 105 can drag segment 219 to a desired position on display unit 113 to form a new route (or second route). To this end, the editing reception unit 121 is configured to generate a copy of segment 219. The copy of segment 219 can be considered as the new route. The editing reception unit 121 is further configured to receive user input from user 105 indicating position displacement information for displacing the position of the new route. The editing reception unit 121 is further configured to displace the position of the original / first route defined by segment 219 on display unit 113 based on the position displacement information to form a new route defined by the second route 215. Waypoints of the new route, such as 213a-213f, are updated based on the displacement of the position of the original route on display unit 113.

[0054] In one embodiment, the display data generation unit 123 is configured to generate display data for simultaneously displaying the first route 203 and the second route 209. As shown in Figure 4, both the first route 203 and the second route 209 are displayed. Also, as shown in Figure 5, both the first route 203 and the second route 215 are displayed. This allows the user 105 to access both the original route (i.e., the first route 203) and the edited route (the second route 215). Furthermore, by displaying both routes simultaneously, the user 105 can compare the original route and the edited route. In addition, since route editing can be started simply by tapping the edit menu 211a, only one user operation is required to start route editing. Thus, according to the embodiment of the present invention, the time lag that existed in conventional solutions known in the art before starting route editing is minimized. Furthermore, the route editing support device 101 enables the user 105 to edit routes of any distance. In other words, the user 105 can edit routes without distance limitations.

[0055] To this end, user interface 200a may correspond to a user interface that may be displayed before editing the first route 203, and user interface 200b or user interface 200c may correspond to a user interface that may be displayed during editing the first route 203.

[0056] According to one embodiment, the display data generation unit 123 is further configured to hide either the first route 203 or the second route 209 based on specific conditions.

[0057] Figure 6 shows a user interface 300 according to an exemplary embodiment in which one of the first route 203 or the second route 209 is hidden based on one or more conditions. The display data generation unit 123 controls the display unit 113 to hide one of the first route 203 and the second route 209 based on a predetermined time. For example, the display data generation unit 123 may hide the first route 203 after a predetermined time has elapsed. In some embodiments, the user 105 can specify the predetermined time.

[0058] In another embodiment, the display data generation module 123 is further configured to control the display 113 to hide either the first route 203 or the second route 209 based on user input indicating a selection of either the first route 203 or the second route 209. For example, user 105 may select the second route 209 for navigation. The first route 203 may then be hidden by the display data generation unit 123. In particular, the display data generation module 123 fades out the first route 203. According to one embodiment, the user interface 300 may correspond to a user interface that may be displayed after editing the first route 203.

[0059] The display data generation unit 123 further generates the first route 203 displayed on the display unit 113. Conning Information and Route 209 Conning Generate information.

[0060] Figure 7 and Figure 8 shows a user interface 400 that displays coning information 401 for the first route 203 and coning information 403 for the second route 209, according to an exemplary embodiment. Conning Information 401 includes a first set of multiple parameters 405 indicating navigation information for the first route 203. Specifically, Conning Information 401 is the first waypoint group 201a , Includes the first multiple parameter 405 values ​​for each waypoint in 201e.

Conning information 403 also includes the values ​​of the second set of multiple parameters 407 for the departure point 201a and the destination 201e.

[0062] The first multiple parameters 405 and the second multiple parameters 407 include parameters such as position in latitude and longitude, turning radius, safe channel width, planned course and steering method (RL: gradual length navigation, GC: great circle navigation), section course, estimated time of arrival (ETA), maximum speed, minimum speed, and time zone. Furthermore, in some embodiments, the first multiple parameters 405 and the second multiple parameters 407 may include the total length of the first route 203 and the second route 209, respectively.

[0063] Furthermore, the display data generation unit 123 is configured to generate route display data that simultaneously displays the first route 203, the coning information 401 of the first route 203, the second route 209, and the coning information 403 of the second route 209 on the display unit 113. By simultaneously displaying both routes and their respective coning information, the user can compare the two routes based on their respective coning information and select either the first route 203 or the second route 209.

[0064] Furthermore, or alternatively, in some embodiments, the coning information 401 of the first route 203 includes a first alarm notification set, and the coning information 403 of the second route 209 includes a second alarm notification set. The alarm notifications in the first and second sets of alarm notifications are sorted based on a predetermined sorting criterion. In some embodiments, the predetermined sorting criterion corresponds to an order from the most important alarm notification to the least important alarm notification. Alternatively, in some embodiments, the alarm notifications are sorted in order from the most important and most recently occurring issue. That is, the most important and most recent alarm notifications are displayed preferentially.

[0065] According to some embodiments, an alarm notification includes alarm text describing a problem or risk (such as a malfunction of a ship's component or a ship's speed exceeding safety limits), and an alarm icon that graphically indicates the importance of the alarm notification. Since the alarm icon, which visually indicates the importance of the alarm notification, is displayed along with the alarm text, the user can identify the importance of each notification at a glance.

[0066] Furthermore, the display data generation unit 123 controls the display unit 113 to display either the coning information 401 of the first route 203 or the coning information 403 of the second route 209 when one of the first route 203 or the second route 209 is hidden. For example, if the first route 203 is hidden, the coning information 401 of the first route 203 will then fade out.

[0067] In some embodiments, the editing reception unit 121 is further configured to accept one or more user inputs as user settings, associated with at least one of the coning information 401 of the first route 203 and the coning information 403 of the second route 209. The one or more user inputs accepted as user settings may include the steering mode to each waypoint (gradual length or great circle), the maximum speed of the vessel, the minimum speed of the vessel, the safe route width, etc. The one or more user inputs accepted as user settings may also include the latitude and longitude (i.e., location) of the waypoints. The editing reception unit 121 is further configured to modify at least one of the first multiple parameters 405 and the second multiple parameters 407 based on the user settings. To this end, the user 105 can modify the first multiple parameters 405 and / or the second multiple parameters 407 by user settings.
