[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0046] Before introducing the technical solution provided by the embodiment of the present invention, an exemplary application scenario can be first described. During the travel of the target ship, the predicted meteorological data of the target ship at the corresponding estimated arrival time can be determined in real time according to the current position of the target ship and the position information of at least one subsequent navigation station, and then the travel safety of the target ship can be determined based on the predicted meteorological data.

[0047] Figure 1 A flowchart of a route safety determination method provided in an embodiment of the present invention. This embodiment can be applied to scenarios. The route safety determination method provided in this embodiment can be executed by a client, or by a server, or by a client and a server in cooperation.

[0048] like Figure 1 As shown, the method specifically comprises the following steps:

[0049] S110. During the travel of the target ship, the average speed of the target ship in the remaining mileage is determined according to the current position and the sailing route of the target ship.

[0050] For each ship, the method of ensuring its navigation safety is the same. In this embodiment, one of the ships is taken as an example to illustrate, and the ship introduced at this time is regarded as the target ship.

[0051] It should be noted that, during the navigation of the target ship, its navigation data can be dynamically analyzed to determine how the target ship should navigate based on the analysis results, thereby achieving the effect of ensuring the navigation safety of the target ship.

[0052] Generally, before the target ship travels, its navigation route can be determined first, so that the target ship travels according to the navigation route. The navigation route includes the location information of the starting position, the destination position and at least one terminal. The terminal can be understood as a physical or virtual temporary stop position point. The target ship can travel according to the navigation route. During the travel process, the average speed of the target ship in the remaining mileage can be determined according to the pre-set periodic task. The navigation route also includes the destination time to reach the destination position.

[0053] Among them, the periodic task can be a task of determining the average speed and predicting weather data every five minutes or one minute. When the target ship travels according to the navigation route, there are certain differences in the positions it reaches at different times, and the position it reaches can be used as the current position. The remaining mileage can be the mileage between the current position and the destination position.

[0054] Specifically, during the process of the target ship traveling according to the navigation route, the current position of the target ship can be determined in real time or periodically. According to the current position and the destination position in the navigation route, the remaining mileage of the target ship, that is, the remaining mileage that the target ship needs to travel, can be determined. According to the remaining mileage, the current time of the target ship, and the destination time of arriving at the destination position, the average speed of the target ship corresponding to the remaining mileage can be determined.

[0055] In this embodiment, the average speed of the target ship in the remaining mileage is determined according to the current position and the navigation route of the target ship, including: determining the navigation distance from the current position to the next navigation point and the navigation distance between two adjacent unreached navigation points according to the current position of the target ship and the position data of multiple navigation points in the navigation route; and determining the average speed of the target ship in the remaining mileage based on all the navigation distances obtained, the estimated arrival time and the current time.

[0056] It should be noted that the navigation route may include multiple terminal stations. When determining the remaining mileage, it is mainly determined based on the terminal stations that the target ship has not reached among the multiple terminal stations.

[0057] The location data of the current location and the terminal can be represented by longitude and latitude coordinates. The navigation distance from the current location to the next terminal can be determined based on the coordinate data of the current location and the coordinate data of each terminal that has not been reached. The navigation distance between any two adjacent terminals that have not been reached can be determined based on the coordinate data of any two terminals that have not been reached. The remaining mileage can be determined by calculating the navigation distances of all the terminals that have not been reached after the current location.

[0058] In this embodiment, the advantage of determining the remaining mileage based on the current position and the navigation point is that the target ship may have a driving deviation during the driving process, and the accuracy of the remaining mileage determination can be improved based on the above method.

[0059] Further, after determining the remaining mileage, the average speed of the target ship can be determined based on the current time and the estimated arrival time in the navigation route. Optionally, the time difference is determined by the estimated arrival time and the current time. By calculating the ratio of the remaining mileage and the time difference, the average speed corresponding to the remaining mileage is obtained.

[0060] In this embodiment, the advantage of determining the average speed is that the estimated arrival time of the target ship can be determined as accurately as possible, thereby obtaining the predicted meteorological data corresponding to the estimated arrival time.

[0061] S120: Determine at least one adjusted speed according to the average speed and a preset speed adjustment step.

[0062] It should be noted that there is a certain deviation in determining the safety attributes of the target ship by only relying on the average speed to determine the predicted meteorological data for the estimated arrival time. Based on this, the speed can be adjusted on the basis of the average speed to determine the speed corresponding to the target ship under safe driving conditions based on the adjusted speed.

[0063] The preset speed adjustment step is how to adjust the speed based on the average speed. The number of at least one adjusted speed can include multiple, and the specific number is related to the speed adjustment step and the number of adjustments. Optionally, the preset speed adjustment step is 2km / h, and the number of adjustments can be 5 times. Then, the speed can be adjusted up or down based on the average speed to obtain at least one adjusted speed.

[0064] Specifically, after obtaining the average speed, the step size can be adjusted according to the average speed and the preset speed, and the average speed can be adjusted upward to obtain at least one adjusted speed, and the average speed can be adjusted downward to obtain at least one adjusted speed.

[0065] It should also be noted that the preset speed adjustment step can be set according to actual needs, and the above-mentioned values ​​are only exemplary and not limiting.

[0066] In this embodiment, determining at least one adjusted speed according to the average speed and the preset speed adjustment step includes: adjusting the average speed according to the preset speed adjustment step to obtain multiple adjusted speeds.

[0067] The preset speed adjustment step length may be pre-set to determine the adjustment value of the speed. Optionally, the preset speed adjustment step length may be 2 km / h, or 1 km / h, etc. The user may set the speed adjustment step length according to actual needs. After determining the speed adjustment step length, the average speed may be adjusted in sequence based on the average speed and the preset adjustment times to obtain multiple adjusted speeds.

[0068] Specifically, the average speed can be adjusted in sequence according to a preset speed adjustment step, and the number of adjustments can be set according to preset requirements. Based on this, the above method can obtain multiple adjusted speeds on the basis of the average speed.

[0069] S130. For the at least one adjusted speed, determine an estimated arrival time corresponding to the unreached terminal point according to the adjusted speed, the current position and position data of a plurality of unreached terminal points.

[0070] After obtaining a plurality of adjusted speeds, the estimated arrival time of the target ship at the unreached destination point at each adjusted speed can be determined.

[0071] The current position is the current position of the target ship, which can be represented by longitude and latitude coordinates. The corresponding position of each unreached terminal can also be determined, and the position data of each unreached position can be obtained. The estimated arrival time is the time information of arriving at the corresponding terminal determined by adjusting the speed.

[0072] Specifically, for any adjusted speed, the time when the target ship reaches each unreached terminal can be determined based on the mileage information from the current position to each unreached terminal and the adjusted speed, and this time is used as the estimated arrival time.

[0073] In this embodiment, the method of determining the estimated arrival time corresponding to the unreached terminal station according to the adjusted speed, the current position and the position data of multiple unreached terminal stations includes: determining the mileage data from the current position to each unreached terminal station according to the current position and the position data of each unreached terminal station; determining the estimated time information for the target ship to travel from the current position to each unreached terminal station based on the mileage data and the adjusted speed; and determining the estimated arrival time of the target ship from the current position to each unreached terminal station according to the current time and the estimated time information for arriving at each unreached terminal station.

[0074] Exemplarily, the unreached terminal points are c1, c2, c3, c4, etc., and they are c1, c2, c3, c4 in the order of arrival. For the unreached terminal point c3, the first distance from the current position to the unreached terminal point c1, the second distance from the unreached terminal point c1 to the unreached terminal point c2, and the third distance from the unreached terminal point c2 to the unreached terminal point c3 can be calculated according to the current position of the target ship. By accumulating the first distance, the second distance and the third distance, the mileage data S of the unreached terminal point c3 is obtained. According to the mileage data S of the unreached terminal point c3 and the adjusted speed V, the estimated time information of the target ship traveling to the unreached terminal point C3 is determined. According to the current time and the estimated time information of the unreached terminal point C3, the estimated arrival time of the target ship from the current position to the unreached terminal point C3 is obtained. Based on the above method, the estimated arrival time of the target ship from the current position to each unreached terminal point can be obtained.

[0075] S140, obtaining the forecasted meteorological data of the unreached destination at the corresponding estimated arrival time, and determining the safety attribute of the navigation route according to the forecasted meteorological data.

[0076] Among them, after obtaining the estimated arrival time of the target ship at each unreached terminal, the forecasted meteorological data of the corresponding estimated arrival time can be obtained according to the latitude and longitude data of the unreached terminal. The advantage of determining the forecasted meteorological data is that the safety of the target ship traveling to the corresponding location can be determined in time. The safety attribute is used to characterize the safety of the target ship traveling to the corresponding unreached terminal according to the navigation route. Generally, the higher the safety attribute, the higher the safety factor of the target ship.

[0077] Specifically, the forecasted meteorological data corresponding to the estimated arrival time of the unreached destination is obtained. After the forecasted meteorological data is obtained, the safety attribute of each navigation route corresponding to the adjusted speed can be determined.

[0078] It should be noted that the higher the safety attribute, the safer the target ship is, and vice versa.

[0079] The technical solution provided by the embodiment of the present invention can determine the average speed of the target ship in the remaining mileage according to the current position and navigation route of the target ship during the navigation process, and then determine multiple adjusted speeds according to the average speed and the preset speed adjustment step. For each adjusted speed, the estimated arrival time corresponding to each unreached navigation station can be determined based on the position data of multiple unreached navigation stations after the adjusted speed and the current position. At this time, the predicted meteorological data of the estimated arrival time can be obtained, and then the safety attributes of the navigation route can be determined based on the predicted meteorological data, which solves the problem that the safety of ships traveling according to the route cannot be effectively and dynamically determined in the prior art, resulting in driving risks, and realizes the predicted meteorological data that can dynamically determine the navigation route, and then determine the safety of the target ship at the corresponding driving position based on the predicted meteorological data, and adjust the effect of the ship's navigation information based on the safety.

[0080] Figure 2 A flow chart of a route safety determination method provided in an embodiment of the present invention. Based on the aforementioned embodiment, "determining the safety attributes of the navigation route according to the predicted meteorological data" can be further refined. The specific implementation method can refer to the detailed description of the present technical solution, wherein the technical terms that are the same as or corresponding to the aforementioned embodiment are not repeated in this embodiment.

[0081] like Figure 2 As shown, the method includes:

[0082] S210: Determine the forecast weather data of the unreached terminal according to the latitude and longitude data of the unreached terminal and the corresponding estimated arrival time.

[0083] The longitude and latitude data are the location information of each unreached terminal. The estimated arrival time is the time information of the target ship traveling to the corresponding unreached terminal. For different unreached terminals, the meteorological data corresponding to different estimated arrival times are different. The meteorological data of the unreached terminal at the estimated arrival time can be predicted based on the existing meteorological forecast software, and this meteorological data is used as the predicted meteorological data.

[0084] It should be noted that for different adjusted speeds, there are certain differences in the estimated arrival time at each terminal, and accordingly, there are certain differences in the predicted meteorological data.

[0085] In this embodiment, when the target ship is sailing at sea, data such as wave height, wave direction, wind speed, wind height, water flow rate and direction will have a certain impact on the safety of the target ship. Based on this, the predicted meteorological data of the estimated arrival time but not reaching the destination point can be obtained.

[0086] Optionally, the predicted meteorological data includes at least data under multiple indicators, and the multiple indicators include at least one of wind speed, wind height, wave height, wave direction, flow velocity, flow rate and air pressure.

[0087] It can be understood that the forecasted meteorological data corresponding to the estimated arrival time can be obtained based on the latitude and longitude data of each unreached terminal. That is, the wind speed value, wind height value, wave height value, wave direction value, water flow direction value, water flow direction value and air pressure value of each unreached terminal at the estimated arrival time are obtained.

[0088] The benefit of obtaining forecasted weather data is that, based on the forecasted weather data of the target ship arriving at the corresponding navigation point, the safety of the target ship when it adjusts its speed accordingly can be determined.

[0089] S220. For the predicted meteorological data under the same indicator, the estimated meteorological data of two adjacent air stations are interpolated to draw a meteorological trend chart corresponding to each indicator, so as to determine the safety attribute of the navigation route according to the meteorological trend chart.

[0090] Among them, for the predicted meteorological data under each indicator, the predicted meteorological data can be interpolated according to the longitude and latitude data of two adjacent flight stations to obtain the predicted meteorological data between the two adjacent flight stations.

[0091] The weather trend chart is drawn based on the target ship's forecast weather data. For each indicator, there is a corresponding weather trend chart.

[0092] Specifically, for each adjusted speed, the forecasted meteorological data of all unreached destinations under each index can be obtained. The forecasted meteorological data of two adjacent unreached destinations can be interpolated to obtain the meteorological trend graph corresponding to each index under the adjusted speed.

[0093] For example, the meteorological trend graph corresponding to the index wind speed, the meteorological trend corresponding to the index swell height, the meteorological trend corresponding to the index wave height, and the meteorological trend corresponding to the index longitudinal flow velocity can be found at Figure 3 The horizontal axis in the weather trend chart represents the estimated arrival time, and the vertical axis represents the specific value under the corresponding indicator.

[0094] In this embodiment, if the warning meteorological data is determined based on the meteorological trend chart and the preset warning threshold, the first terminal and the second terminal corresponding to the warning meteorological data are determined, and the arrival time of the first terminal is earlier than the arrival time of the second terminal; the average speed or the length of stop at the first terminal is re-determined with the first terminal as the starting point to determine the safety attributes of the navigation route.

[0095] Among them, the preset warning threshold is a preset red line value for safe navigation of the target ship. For example, for the index wave height, the preset warning threshold is 5m, that is, a wave height higher than 5m indicates that there is a certain risk in the navigation of the target ship. It can be determined whether it is warning meteorological data based on the ordinate value corresponding to each horizontal coordinate in the meteorological trend chart and the preset warning threshold. Optionally, if the ordinate values ​​of multiple consecutive horizontal coordinates are greater than the preset warning threshold, it means that there is a driving risk when the target ship is traveling during this time period.

[0096] It should be noted that the time length formed by the continuous multiple horizontal coordinates is greater than the preset time length threshold. Of course, if one of the continuous multiple horizontal coordinates or the vertical coordinate values ​​of the preset number are greater than the preset warning threshold, it still means that there is a risk when the target ship is traveling in this time period, and it can continue to be processed.

[0097] The predicted meteorological data in the meteorological trend chart that is higher than the preset warning threshold is used as the warning meteorological data. The starting unreached terminal point and the ending unreached terminal point associated with the warning meteorological data can be determined. For example, the unreached terminal points corresponding to the warning meteorological associated data are A1, A2, and A3. The order of arrival is A1, A2, and A3. At this time, the starting unreached terminal point is A1 and the ending unreached terminal point is A3. Based on this, it can be known that the first terminal point is A1 and the second terminal point is A2. The average speed can be re-determined or the stop time at the first terminal point can be determined with the first terminal point A1 as the starting point, so as to determine the safety attributes of the navigation route based on the updated average speed or the stop time at the first terminal point.

[0098] In this embodiment, after the forecasted meteorological data of the estimated arrival time is obtained, a target report can be generated according to the forecasted meteorological data of the estimated arrival time.

[0099] Optionally, the target report may include a report diagram corresponding to each dimension. The report diagram can be found in Figure 3 Results shown.

[0100] Generate a target report based on the forecasted weather data corresponding to the estimated arrival time.

[0101] It can be understood that: for each adjusted speed, a trend diagram corresponding to different meteorological dimensions can be determined, that is, a target report. The helmsman corresponding to the target ship can determine the driving safety of the target ship based on the report, and whether to adjust the speed or driving plan of the target ship.

[0102] Of course, the solution provided in the embodiment of the present invention can also determine the corresponding driving plan according to the trend chart. The driving plan at this time is mainly to adjust the navigation speed or docking time of the corresponding terminal of the target ship to achieve the control of the target ship from the above two dimensions, thereby ensuring the driving safety of the target ship.

[0103] The technical solution provided by the embodiment of the present invention can determine the average speed of the target ship in the remaining mileage according to the current position and navigation route of the target ship during the navigation process, and then determine multiple adjusted speeds according to the average speed and the preset speed adjustment step. For each adjusted speed, the estimated arrival time corresponding to each unreached navigation station can be determined based on the position data of multiple unreached navigation stations after the adjusted speed and the current position. At this time, the predicted meteorological data of the estimated arrival time can be obtained, and then the safety attributes of the navigation route can be determined based on the predicted meteorological data, which solves the problem that the safety of ships traveling according to the route cannot be effectively and dynamically determined in the prior art, resulting in the existence of driving risks, and realizes the predicted meteorological data that can dynamically determine the navigation route, and then determine the safety of the target ship at the corresponding driving position based on the predicted meteorological data, and adjust the ship's navigation information based on the safety.

[0104] As an alternative embodiment of the above embodiment, Figure 4 A schematic diagram of a route safety assurance method provided by an embodiment of the present invention is shown in FIG. Figure 4 As shown, the implementation of the method mainly includes three parts, namely, a data preprocessing part, a report generating part and a report exporting part.

[0105] The data processing part mainly includes loading routes, calculating the distance from the current ship position to each waypoint on the remaining route, setting the calculated speed, the time of arrival at each waypoint at different speeds, and the weather difference of the route; the report generation part includes generating encounter weather maps, generating route weather overview maps, generating sea condition charts encountered at different speeds, report generation, and report format conversion; the report export part includes uploading reports to the server, sending reports by email, and storing report address information.

[0106] The following is a detailed introduction to the specific content of each part:

[0107] First load the route file, which includes the route name, the latitude and longitude data of each waypoint (station) to be reached, and the departure time.

[0108] While the target ship is traveling according to the route file, the safety attributes of the navigation route can be determined in real time, or the safety attributes of the navigation route can be determined periodically.

[0109] The remaining distance for the target ship to reach the remaining unreached waypoints can be determined based on the current position and navigation route of the target ship. Further, the average speed can be determined based on the remaining distance.

[0110] Optionally, calculate the remaining distance based on the current ship position:

[0111] Among them, s remain is the remaining total distance, s c The distance from the current location to the next unreached destination. It is the distance information from the next unreached terminal to all subsequent terminal stations.

[0112] The average speed can be determined based on the remaining distance:

[0113] Among them, v avg is the average speed of the remaining mileage, s remain is the remaining mileage, t eta is the final arrival time of the navigation route, t c For the current moment.

[0114] After the average speed is obtained, the average speed may be adjusted according to a preset speed adjustment step to obtain at least one adjusted speed.

[0115] After obtaining at least one adjusted speed, the estimated arrival time of the target ship at the corresponding unreached terminal can be determined according to each adjusted speed and the navigation route. That is, for each adjusted speed, a set of estimated arrival times of the target ship at the corresponding unreached terminal can be obtained.

[0116] After the target ship reaches the estimated arrival time of the corresponding unreached navigation point at different adjusted navigation speeds, the longitude and latitude data of each unreached navigation point can be obtained. According to the longitude and latitude data and the estimated arrival time of each unreached navigation point, the predicted meteorological data of the target ship can be determined. That is, the predicted meteorological data of the target ship at each unreached navigation point at each adjusted navigation speed can be obtained.

[0117] After obtaining the forecasted meteorological data for each unreached navigation point, the forecasted meteorological data for the unreached navigation point can be interpolated according to the longitude and latitude data to obtain the forecasted meteorological data on the navigation route of the target ship.

[0118] For different adjusted speeds, a navigation profile can be generated. The navigation profile can include the target ship's name, route, current time, remaining sailing time, remaining mileage, average speed, and forecasted weather data for different terminals.
