Description

Buoy searching method and system based on airline

Technical Field

The present invention relates generally to the field of computer technology, and more particularly, to a method and system for buoy search based on airline.

Background

With the continuous development of scientific technology, various monitoring systems become mature. For example, in an ocean monitoring system, the characteristics of wide distribution range and long measurement period of monitoring by using a buoy are already the main means of ocean monitoring. In addition, in the atmosphere monitoring system, a float (e.g., a probe balloon) may be used for monitoring.

With the continuous launching of new buoys, the data volume of buoys is increasing. How to quickly and accurately search out buoys which are interested by users is a problem which needs to be solved urgently at present. One existing search method is to determine a rectangular frame by inputting a coordinate range (e.g., latitude and longitude range) for searching. Another search method is to search by entering keywords (e.g., basic attributes of the buoy, such as item name, country, buoy type, etc.).

The existing searching method can only search through the area determined by the regular graph or only search specific keywords. However, in certain applications, a user may wish to search for buoys based on routes before or during a voyage. Therefore, there is a need to search for buoys according to routes.

Disclosure of Invention

The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

The invention aims to provide a method for searching buoys based on routes. This method enables the user to search for buoys based on a particular route, for example, before or during the voyage. The specific process of the method of the invention is that the user inputs an airline to search for buoys around the airline.

A method of searching for a buoy is described, which may comprise: and inputting a route.

In one embodiment, the input route may further include: and drawing the route track on a map interface. The plotted course trajectory is represented in pixel coordinates. In this embodiment, a number of pixel points may then be grabbed on the plotted route trajectory, the grabbed pixel points mapped to geographic coordinates, and the mapped geographic coordinates connected to arrive at a route represented in the form of geographic coordinates. In another embodiment, the input route may further include: a plurality of waypoints are input. In one example, a user may enter a plurality of waypoints in the form of geographic coordinates. In another example, a user may click input multiple waypoints on a map interface. And the route points of the click input are represented in the form of pixel points. In yet another embodiment, the input pattern may further comprise: and selecting the stored routes. In one example, the user may invoke an airline that has been previously stored to re-search for buoys around the airline. In another example, the user may select an already stored route, modify some waypoints, and enter the modified route.

The method may further include; and forming an area to be searched by taking the flight path as a center. In one embodiment, forming the area to be searched may further include translating the distance d outward along both sides of the flight line centered on the flight line. In one implementation, a sub-leg between two waypoints on the route may be translated outward in the direction of the perpendicular to the sub-leg by a distance d centered on the sub-leg. In the case of a continuous curve of the course, each point on the course may be translated outward by a distance d in the direction of the perpendicular to the tangent of that point centered on that point. The distance d may range from 1 to 10 nautical miles. In one embodiment, a circle may be drawn with a distance d as a radius from a point on the route. In some cases, several waypoints may be selected on the route; and drawing a circle by taking the selected route point as a circle center and d as a radius, and respectively connecting the external common tangent lines of two adjacent circles at two sides of the route. The distance d may range from 1 to 10 nautical miles.

The method may further include; and searching for a buoy based on the area to be searched. In one embodiment, searching for buoys may be accomplished by comparing all geographic coordinates within the area to be searched to the geographic coordinates of buoys within the buoy database to determine a set of buoys that fall within the area to be searched.

Another buoy search system is also described, which may include: an input module configured to input a route; a forming module configured to form a region to be searched centering on the route; and a search module configured to search for a buoy based on the area to be searched. In one embodiment, the search module is further configured to compare all of the geographic coordinates within the area to be searched with the geographic coordinates of the buoys within the buoy database to determine a set of buoys that fall within the area to be searched. In one embodiment, the buoy search system may optionally include a display module that may be configured to display the searched buoys. For example, the display module may be configured to display the buoy in various display forms (such as text, graphics, lists).

Another buoy search system is also described, comprising: a memory; and a processor in communication with the memory, the processor configured to: inputting a route; forming a region to be searched by taking the route as a center; and searching for a buoy based on the area to be searched.

Further, a computer-readable medium is described that stores processor-executable code executable by a processor to perform operations comprising: inputting a route; forming a region to be searched by taking the route as a center; and searching for a buoy based on the area to be searched.

The invention aims to provide a method for searching buoys based on routes. This method enables the user to search for buoys based on a particular route, for example, before or during the voyage.

In some situations, the user may wish to see before navigating whether a buoy from another country is located near the airline to salvage during the course of the navigation. In some cases, the method may allow a user to query the location of buoys present around an airline as the user customizes the airline prior to navigating. In other cases, the user may further modify the airline based on buoys around the airline. The method of the invention enables the user to search for buoys based on a particular airline in various situations.

FIG. 1 shows a flow diagram 100 for searching buoys based on an airline, according to one embodiment of the invention.

In step 110: and inputting a route.

In one embodiment, the input route may further include: and drawing the route track on a map interface. The plotted course trajectory may be represented in pixel coordinates. Alternatively, the pixel coordinates may be mapped to geographic coordinates. The geographic coordinates may be spherical coordinates representing the location of the ground point in latitude, longitude. The spherical coordinates are the latitude and longitude representing the position of the ground point. In one example, mapping pixel coordinates on a map interface (plane) to geographic coordinates on a sphere may be accomplished by various projection approaches, such as, but not limited to, an equiangular tangent azimuth projection (spherical polar projection), an equidistant secant cone projection, an isoproduct secant cone projection, an equiangular tangent cylinder projection (also known as a mercator projection), a gaussian-kruger projection (equiangular cross-cut elliptic cylinder projection), a universal cross-axis mercator projection (simply referred to as a UTM projection). In one example, a user may use a finger or stylus to draw a course trajectory on a mapping interface. In another example, a user may use a mouse to draw a course trajectory on a mapping interface. In some cases, the entered route may be stored.

In another embodiment, the input route may further include: a plurality of waypoints are input. In one example, a user may enter a plurality of waypoints in the form of geographic coordinates. For example, a user may enter a list of waypoints represented in the form of geographic coordinates. In another example, a user may click input multiple waypoints on a map interface. And the route points of the click input are represented in the form of pixel points. For example, a user may click on multiple pixel points. The selected plurality of pixel points are mapped to geographic coordinates. The clicked pixel points are mapped to geographical coordinates in a projection manner such as that mentioned above. The mapped geographic coordinates are concatenated into the route to arrive at the route in the form of geographic coordinates. Likewise, geographic coordinates may be represented in latitude and longitude information. The number of input waypoints is not less than three. In some cases, the entered route may be stored.

Furthermore, in yet another embodiment, the input lane may further include: and selecting the stored routes. In one example, a user may invoke an airline that has been previously stored to re-search for buoys around the airline, and the resulting search results may differ due to movement of the buoys. In another example, the user may select an already stored route, modify some waypoints on the stored route, and enter the modified route. The airlines may be stored in the form of geographic coordinates. Likewise, geographic coordinates may be represented in latitude and longitude information. For example, the user may have completed the first half-voyage, and the user may call a previously stored course, optionally delete the course of the first half-voyage, and search based on the course of the second half-voyage. Or, the user may need to perform fine adjustment on the route of the second half voyage based on the search result of the second half voyage, and perform the search again to find a more suitable route of the second half voyage.

In step 120: and forming an area to be searched by taking the flight path as a center. Forming the region to be searched may further include: and (5) outwards translating the distance d along the two sides of the route by taking the route as the center to form a region to be searched. The distance d ranges from 1 to 10 nautical miles. In a preferred embodiment, the distance d may be 5 nautical miles. In another preferred embodiment, the distance d may be 1 nautical mile.

Referring to fig. 2, in an embodiment of inputting a route by inputting a plurality of route points, a sub-route segment between two route points on the route may be translated outward by a distance d along a perpendicular direction of the sub-route segment with the sub-route segment as a center, and the translation area is a sub-area to be searched of the sub-route segment. In some cases, the sub areas to be searched may overlap with each other. For example, the sub-segment between the two waypoints HXD21 and HXD22 may be translated outward by a distance d along the perpendicular direction of the sub-segment with the sub-segment as the center, and the translation region is the sub-to-be-searched region of the sub-segment between the waypoints HXD21 and HXD 22. As shown in FIG. 2, three sub-areas to be searched (shown as three shaded rectangles in FIG. 2) between waypoints HXD21, HXD22, HXD23, HXD24 are merged to form an area to be searched for the entire airline. It should be noted that only four waypoints are shown in FIG. 2 as being connected into three sub-waypoints, but any more or fewer waypoints may be included in the present invention. The input waypoints are not less than three waypoints.

Referring to fig. 3, in another embodiment of inputting a route by inputting a plurality of route points, a circle may be drawn with a distance d from each route point as a center of the circle as a radius, and external common tangents of two adjacent circles are connected to both sides of the route, respectively. As shown in FIG. 3, a circle may be drawn with the waypoints HXD31, HXD32, HXD33 as centers and the distance d as a radius. Two external common tangent lines of two circles with the waypoints HXD31 and HXD32 as the centers are drawn, and two external common tangent lines of two circles with the waypoints HXD32 and HXD33 as the centers are drawn at the same time. The area formed by the external common tangent and a part of each circumference is taken as the area to be searched. It should be noted that only three waypoints are shown in FIG. 3, but the present invention may include more waypoints.

Alternatively, in one embodiment of entering a flight path by drawing a flight path trajectory, a plurality of waypoints may be grabbed on the flight path and then the area to be searched may be formed in the manner described with reference to FIGS. 2 and 3. Preferably, a plurality of route points can be grabbed at equal intervals on the route track to form a plurality of sub-route segments, or the grabbed route points can be used as circle centers to draw circles, and the outer common tangents of two adjacent circles are respectively connected to two sides of the route.

In particular, in one example where the trajectory is a continuous curve, referring to FIG. 4, each point may be translated outward a distance d in the direction of the perpendicular to the tangent of the point centered on the point. The translation area is the sub-area to be searched of the point. And taking a union set aiming at all the sub areas to be searched to form the area to be searched of the whole airline.

In another example where the course trajectory is a continuous curve, referring to FIG. 5, a circle may be drawn with each point on the course as the center and the distance d as the radius. The area in each circle is the sub-area to be searched for of the point. And taking a union set aiming at all the sub areas to be searched to form the area to be searched of the whole route. It should be noted by those skilled in the art that the manner described with reference to fig. 5 of drawing a circle with distance d as a radius from each point on the route to form the area to be searched is applicable to all route input manners, including a plurality of route points being input.

At step 130; the buoy is searched based on the area to be searched.

In one embodiment, the buoys may be searched by comparing all of the geographic coordinates within the area to be searched to the geographic coordinates of the buoys within the buoy database to determine a set of buoys that fall within the area to be searched.

In some cases, the area to be searched for each sub-route segment may be taken and aggregated to form an area to be searched for the entire route, and then buoys may be searched based on the area to be searched for the entire route.

In some alternative cases, the sub-area to be searched for each sub-flight segment may be calculated separately, the geographic coordinates of the sub-area to be searched for may be compared to the geographic coordinates of the buoys within the buoy database to determine the set of buoys falling within the sub-area to be searched for, and then the union of the buoys within the area to be searched for all sub-flight segments may be determined as the set of buoys associated with the entire airline.

Optionally, the process may further comprise: the searched buoys are displayed and may be displayed in various display manners, such as text, lists, graphics, and the like.

In one particular embodiment, the user may select different translation distances to search for buoys for the same route. The user may decide whether the airline needs to be changed based on two different search results based on different translation distances. For example, in one scenario, a user may search for a buoy of another country near an airline, and the user may salvage the buoy by modifying the airline.

In addition, in marine monitoring systems, the buoy may float to a certain extent under the influence of wind, waves, or tides. In another embodiment, the user may select a stored route in the system to search for the buoy again. For example, the user searches for buoys associated with an airline by selecting a stored airline after having completed half the flight. The user can determine whether the second half route needs to be adjusted according to the search result.

In yet another particular embodiment, a user may enter multiple routes, determining which route to select based on search results associated with each route.

In yet another particular embodiment, the user may retrieve buoys around an airline based on the airline. The searched buoy gives an alarm in case of detecting climatic and marine disasters such as hurricanes, typhoons, tornadoes, ice storms, floods and droughts, as well as storm tides, red tides, etc. The user may re-order the airline based on the alert to ensure that the voyage can be completed safely.
