Technical Field
The invention belongs to the technical field of navigation operation, relates to a planning method of a planned route, and particularly relates to a route planning method of an automatic association route point library.
Background
The process of planning the air route is the process of selecting the waypoint. Usually, a ship sails in a certain fixed sea area, and the selected waypoints are also fixed. Therefore, how to use the existing experience to rapidly make a reasonable planned route becomes a difficult point for making the planned route.
In marine operations (e.g., marine plotting tables, etc.), it is often necessary for a user to make a planned course and then use the course for course monitoring during a marine voyage. Currently, planning routes can be generally divided into three types: firstly, inputting longitude and latitude coordinates of each route point one by a user; secondly, manually clicking route points in the chart area by a user; and thirdly, the former two are combined for use.
Although the three methods can realize the selection of the waypoints and the making of the planned route, the three methods do not utilize the selection experience of the existing waypoints to realize the rapid making of the planned route.

and 3, associating the waypoints manually and randomly clicked by the user with the waypoint library established in the step 1, and assisting navigation operators in finishing the selection of the waypoints and the establishment of the air route.
Further, the step 1 includes the steps of:
(1) starting an interface thread and a database thread;
(2) if the user selects to insert the waypoint library, determining waypoints in an interface thread by adopting a man-machine interaction input mode or a manual click mode in a chart area, sending a waypoint insertion signal and the determined waypoint coordinates to a database thread by the interface thread, and inserting the waypoints into the waypoint library by the database thread after receiving the waypoint insertion signal;
(3) if the user selects to modify the waypoint library, the waypoints are modified in the interface thread in a man-machine interaction mode, then waypoint updating signals are sent to the database thread, and the waypoints of the waypoint library are updated after the database thread receives the signals.
Further, the step 3 includes the steps of:
(1) capturing viewport coordinates of a finger-up position of a user when the user manually randomly selects an airway point in a chart area;
(2) converting the coordinates of the viewport into the plane coordinates of the chart according to the scale from the viewport to the chart;
(3) converting the plane coordinates of the chart into geodetic plane coordinates according to a scale of the chart;
(4) converting the geopland coordinates into geographic longitude and latitude coordinates according to parameters such as mercator projection and the like;
(5) calculating the distance between each waypoint in the waypoint library and the waypoint manually and randomly clicked by the user according to the distance measuring formula, and judging whether the distance is smaller than a set threshold value or not;
(6) if the waypoints with the distance between the waypoints manually and randomly selected by the user and the waypoints smaller than the set threshold value are inquired in the waypoint library, popping up a prompt box and inquiring whether the user selects the waypoints in the waypoint library or not;
(7) if the user selects the waypoints in the waypoint library, popping up a waypoint list meeting the threshold condition, so that the user can select one waypoint and wait for confirmation;
(8) after the user confirms, the waypoints in the waypoint library are replaced by the waypoints manually and randomly clicked by the user in the chart area, so that the waypoint selection and the route making are completed.
The invention has the advantages and positive effects that:
1. the invention can make a planned route by using the existing experience, simultaneously improves the convenience and the accuracy in the route making process, and can meet the application requirements of navigation operation more greatly.
2. The invention provides a method for automatically associating a waypoint library, which utilizes the selection experience of the existing waypoints to achieve the aim of assisting navigation operators to quickly make a planned route.

Detailed Description
The embodiments of the invention will be described in further detail below with reference to the accompanying drawings:
a method for making routes of an automatic associated waypoint library comprises the following steps:
step 1, establishing a waypoint library, and updating waypoints of the waypoint library;
the step 1 comprises the following specific steps, as shown in fig. 1:
(1) starting an interface thread and a database thread;
(2) if the user selects to insert the waypoint library, determining waypoints in an interface thread by adopting a man-machine interaction input mode or a manual click mode in a chart area, sending a waypoint insertion signal and the determined waypoint coordinates to a database thread by the interface thread, and inserting the waypoints into the waypoint library by the database thread after receiving the waypoint insertion signal;
(3) if the user selects to modify the waypoint library, the waypoints are modified in the interface thread in a man-machine interaction mode, then waypoint updating signals are sent to the database thread, and the waypoints of the waypoint library are updated after the database thread receives the signals.
Step 2, as shown in FIG. 2, a user manually and randomly selects an airway point in a chart area through a human-computer interaction interface to make an airway;
and 3, associating the waypoints manually and randomly clicked by the user with the waypoint library established in the step 1, and assisting navigation operators in finishing the selection of the waypoints and the establishment of the air route.
As shown in fig. 4, the step 3 includes the following specific steps:
(1) capturing viewport coordinates of a finger-up position of a user when the user manually randomly selects an airway point in a chart area;
(2) converting the coordinates of the viewport into the plane coordinates of the chart according to the scale from the viewport to the chart;
(3) converting the plane coordinates of the chart into geodetic plane coordinates according to a scale of the chart;
(4) converting the geopland coordinates into geographic longitude and latitude coordinates according to parameters such as mercator projection and the like;
(5) calculating the distance between each waypoint in the waypoint library and the waypoint manually and randomly clicked by the user according to the distance measuring formula, and judging whether the distance is smaller than a set threshold value or not;
in the present embodiment, the set threshold is 100 meters;
(6) if the waypoint with the distance between the waypoint and the waypoint manually and randomly selected by the user and smaller than the set threshold value is inquired in the waypoint library (namely the waypoint meeting the threshold value condition is inquired in the waypoint library), popping up a prompt box and inquiring whether the user selects the waypoint in the waypoint library;
in this embodiment, when the user manually and randomly selects the waypoint, if there is a waypoint in the waypoint library near the selected point, when the user pops up the finger, a prompt dialog box pops up to inquire whether to select the waypoint in the waypoint library, so as to provide quick operation for the user. As shown in FIG. 3, the dots on non-routings are waypoints in the waypoint library.
(7) If the user selects the waypoints in the waypoint library, popping up a waypoint list meeting the threshold condition, so that the user can select a specific waypoint and wait for confirmation;
in this embodiment, the waypoints meeting the threshold condition are waypoints within a set threshold range, specifically: waypoints in the waypoint library that are less than 100 meters from the waypoint manually randomly selected by the user.
(8) After the user confirms, the waypoints in the waypoint library are replaced by the waypoints manually and randomly clicked by the user in the chart area, so that the waypoint selection and the route making are completed.
