[0044] The application will be described in further detail below with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are intended to be illustrative only and not limiting of the application. It is also to be understood that the terminology used herein is for the purpose of describing the specific embodiments only and is not intended to be limiting.

It is to be understood that the specific embodiments described herein are intended to be illustrative only and not limiting of the application. It is also to be understood that the terminology used herein is for the purpose of describing the specific embodiments only and is not intended to be limiting.

[0046] Before introducing the technical solutions provided by the embodiments of the application, an exemplary application scenario can be described first. In the process of driving a target ship, predicted meteorological data of the target ship at a corresponding estimated arrival time can be determined according to current position information of the target ship and position information of at least one subsequent navigation station, and then driving safety of the target ship can be determined according to the predicted meteorological data.

[0047] Figure 1 A flowchart of a route safety determination method provided by the embodiments of the application, the embodiments of the application can be applied to the scenario, the route safety determination method provided by the embodiments of the application can be executed by a client, can be executed by a server, or can be executed by the client and the server in cooperation.

[0048] As shown in Figure 1 The method specifically includes the following steps:

[0049] S110, in the process of driving a target ship, determining an average navigation speed of the target ship in a remaining distance according to a current position and a navigation route of the target ship.

[0050] For each ship, the way to ensure the navigation safety of the ship is the same, and in the embodiments, one of the ships is taken as an example to be described, and the ship is taken as a target ship.

[0051] It should be noted that in the process of driving the target ship, the navigation data of the target ship can be dynamically analyzed to determine how the target ship should drive based on the analysis result, so as to achieve the effect of ensuring the driving safety of the target ship.

[0052] Generally, before the target ship sails, a sailing route can be determined for the target ship to sail according to the sailing route. The sailing route includes a starting position, a destination position, and position information of at least one sailing site. The sailing site can be understood as a real or virtual temporary stop position point. The target ship can sail according to the sailing route. During the sailing, an average sailing speed of the target ship in a remaining distance can be determined according to a pre-set periodic task. The sailing route also includes a destination time of reaching the destination position.

[0053] The periodic task can be a task of determining the average sailing speed and predicting the weather data every five minutes or one minute. When the target ship sails according to the sailing route, there is a certain difference in the positions reached at different times, and the positions reached can be taken as a current position. The remaining distance can be a distance between the current position and the destination position.

[0054] Specifically, during the sailing of the target ship according to the sailing 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 sailing route, a remaining sailing distance of the target ship, i.e., a remaining distance to be sailed by the target ship, can be determined. According to the remaining distance, a current time of the target ship, and the destination time of reaching the destination position, an average sailing speed of the target ship in the remaining distance can be determined.

[0055] In this embodiment, according to the current position of the target ship and the sailing route, the average sailing speed of the target ship in the remaining distance is determined, including: according to the current position of the target ship and position data of a plurality of sailing sites in the sailing route, determining a sailing distance from the current position to a next sailing site, and a sailing distance between two adjacent un-reached sailing sites; based on all the obtained sailing distances, a predicted reaching time, and a current time, determining the average sailing speed of the target ship in the remaining distance.

[0056] It should be noted that the sailing route can include a plurality of sailing sites, and when the remaining distance is determined, the un-reached sailing sites of the target ship among the plurality of sailing sites are mainly used for determination.

[0057] The current position and the position data of the sailing site can be represented by latitude and longitude coordinates. According to the coordinate data of the current position and the coordinate data of each un-reached sailing site, the sailing distance from the current position to the next sailing site can be determined. According to the coordinate data of any two adjacent un-reached sailing sites, the sailing distance between the two un-reached sailing sites can be determined. The remaining distance is determined by the sailing distances of all the un-reached sailing sites after the current position.

[0058] In the embodiment, the advantage of determining the remaining distance according to the current position and the station is that the target ship may have a deviation in the running position during the running, and the effect of improving the accuracy of determining the remaining distance can be achieved based on the above manner.

[0059] Further, after the remaining distance is determined, the average speed of the target ship can be determined according to the current time and the estimated arrival time in the navigation route. Alternatively, the time difference is determined by the estimated arrival time and the current time. The average speed corresponding to the remaining distance is obtained by calculating the ratio of the remaining distance and the time difference.

[0060] In the 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, so that the predicted meteorological data corresponding to the estimated arrival time is obtained.

[0061] S120, determining 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 predicted meteorological data of the estimated arrival time of the target ship and then determining the safety attribute of the target ship only by relying on the average speed. Therefore, the speed adjustment can be performed based on the average speed, so that the speed corresponding to the safe running of the target ship is determined based on the adjusted speed.

[0063] The preset speed adjustment step is how much adjustment step is used to obtain the adjusted 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 adjustment times. Alternatively, the preset speed adjustment step is 2 km / h, and the adjustment times can be 5 times. Then, the speed adjustment can be performed upward or downward based on the average speed to obtain at least one adjusted speed.

[0064] Specifically, after the average speed is obtained, the average speed and the preset speed adjustment step can be used to adjust the average speed 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 be further noted that the preset speed adjustment step can be set according to actual needs. The above-mentioned values are only exemplary and are not limited thereto.

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

[0067] The preset speed adjustment step can be preset, and is used to determine an adjustment value of the adjusted speed. Optionally, the preset speed adjustment step can be 2 km / h, or 1 km / h, or the like. A user can set the speed adjustment step according to actual requirements. After the speed adjustment step is determined, the average speed can be adjusted based on the average speed and the preset adjustment times, to obtain a plurality of adjusted speeds.

[0068] Specifically, the average speed can be adjusted according to the preset speed adjustment step. The number of times of adjustment can be set according to preset requirements. Based on this, the above method can obtain a plurality of adjusted speeds based on the average speed.

[0069] S130, for the at least one adjusted speed, according to the adjusted speed, the current position and the position data of the plurality of unarrived stations, determining an estimated arrival time corresponding to the unarrived station.

[0070] After a plurality of adjusted speeds are obtained, an estimated arrival time of the target ship to the unarrived station can be determined under each adjusted speed.

[0071] The current position is a position where the target ship is currently located, and the current position can be represented by latitude and longitude coordinates. For each unarrived station, the position corresponding to the unarrived station can also be determined, and position data of each unarrived position can be obtained. The estimated arrival time is time information determined according to the adjusted speed to arrive at the corresponding station.

[0072] Specifically, for any one adjusted speed, the mileage information from the current position to each unarrived station and the adjusted speed can be used to determine a time when the target ship travels to each unarrived station, and the time is taken as the estimated arrival time.

[0073] In this embodiment, the estimated arrival time corresponding to the unarrived station is determined according to the adjusted speed, the current position and the position data of the plurality of unarrived stations, including: determining mileage data from the current position to each unarrived station according to the current position and the position data of each unarrived station; determining estimated time length information of the target ship from the current position to each unarrived station based on the mileage data and the adjusted speed; and determining an estimated arrival time of the target ship from the current position to each unarrived station according to the current time and the estimated time length information of the target ship to each unarrived station.

[0074] For example, the unarrived airport points are c1, c2, c3, c4, and the arrival order is c1, c2, c3, c4. For the unarrived airport point c3, the first distance from the current position of the target ship to the unarrived airport point c1, the second distance from the unarrived airport point c1 to the unarrived airport point c2, and the third distance from the unarrived airport point c2 to the unarrived airport point c3 can be calculated according to the current position of the target ship. The mileage data S of the unarrived airport point c3 is obtained by adding the first distance, the second distance and the third distance. The estimated time length information of the target ship traveling to the unarrived airport point c3 is determined according to the mileage data S of the unarrived airport point c3 and the adjusted speed V. The estimated arrival time of the target ship traveling from the current position to the unarrived airport point c3 is obtained according to the current time and the estimated time length information of the unarrived airport point c3. The estimated arrival time of the target ship traveling from the current position to each unarrived airport point can be obtained based on the above method.

[0075] In S140, the predicted weather data of the unarrived airport point at the corresponding estimated arrival time is obtained, and the safety attribute of the navigation route is determined according to the predicted weather data.

[0076] In S140, the predicted weather data of the unarrived airport point at the corresponding estimated arrival time is obtained, and the safety attribute of the navigation route is determined according to the predicted weather data.

[0077] Specifically, the predicted weather data corresponding to the unarrived airport point at the corresponding estimated arrival time is obtained. After obtaining the predicted weather data, the safety attribute of the navigation route corresponding to each adjusted speed can be determined.

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

[0079] The technical scheme provided by the embodiment of the present application can determine the average speed of the target ship in the remaining distance according to the current position and the navigation route of the target ship during the driving process of the target ship, and then determine a plurality of adjusted speeds according to the average speed and the preset speed adjustment step. For each adjusted speed, the estimated arrival time corresponding to each un-reached navigation station can be determined according to the adjusted speed and the position data of a plurality of un-reached navigation stations after the current position. At this time, the prediction meteorological data of the estimated arrival time can be obtained, and then the safety attribute of the navigation route can be determined according to the prediction meteorological data, thereby solving the problem that the safety of the ship driving according to the route cannot be effectively determined in the prior art, leading to the driving risk. The prediction meteorological data of the navigation route can be dynamically determined, and then the safety of the target ship at the corresponding driving position is determined according to the prediction meteorological data, and the effect of adjusting the ship navigation information is determined according to the safety

[0080] Figure 2 The safety determination method for the route provided by the embodiment of the present application is based on the foregoing embodiment, and the "determination of the safety attribute of the navigation route according to the prediction meteorological data" can be further refined. The specific implementation can be referred to the detailed description of the technical scheme, and the same or corresponding technical terms as the above embodiment are not described herein.

[0081] As shown in Figure 2 , the method comprises:

[0082] S210, determining the prediction meteorological data of the un-reached navigation station according to the latitude and longitude data of the un-reached navigation station and the corresponding estimated arrival time.

[0083] The latitude and longitude data is the position information of each un-reached navigation station. The estimated arrival time is the time information of the target ship driving to the corresponding un-reached navigation station. For different un-reached navigation stations, the meteorological data corresponding to different estimated arrival times is different. The meteorological data of the un-reached navigation station at the estimated arrival time can be predicted based on the existing meteorological prediction software, and this meteorological data is used as the prediction meteorological data.

[0084] It should be noted that for different adjusted speeds, the estimated arrival time of reaching each navigation station is different, and correspondingly, the prediction meteorological data is also different.

[0085] In this embodiment, when the target ship drives on the sea, the data such as the height of the sea wave, the direction of the sea wave, the wind speed, the wind height, the flow rate and the flow direction of the water will have a certain influence on the safety of the target ship. Based on this, the prediction meteorological data of the un-reached navigation station at the estimated arrival time can be obtained.

[0086] Optionally, the predicted meteorological data at least comprises data of a plurality of indexes, and the plurality of indexes comprises at least one of wind speed, wind height, wave height, wave direction, flow speed, flow volume and air pressure.

[0087] It can be understood that, according to the longitude and latitude data of each non-arrival station, the corresponding predicted meteorological data at the estimated arrival time can be obtained. That is, the wind speed value, wind height value, wave height value, wave direction value, flow direction value, flow speed value and air pressure value of each non-arrival station at the estimated arrival time can be obtained.

[0088] The advantage of obtaining the predicted meteorological data is that, according to the predicted meteorological data of the target ship arriving at the corresponding station, the safety of the target ship traveling at the corresponding adjusted speed can be determined.

[0089] S220, for the predicted meteorological data of the same index, the estimated meteorological data of the adjacent two stations is interpolated to draw a meteorological trend chart corresponding to each index, 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 of each index, the predicted meteorological data of the adjacent two stations can be interpolated according to the longitude and latitude data of the adjacent two stations to obtain the predicted meteorological data between the adjacent two stations.

[0091] The meteorological trend chart is drawn based on the predicted meteorological data of the target ship. For each index, there is a meteorological trend chart corresponding to it.

[0092] Specifically, for each adjusted speed, the predicted meteorological data of all non-arrival stations under each index can be obtained. The predicted meteorological data of the adjacent two non-arrival stations can be interpolated to obtain the meteorological trend chart corresponding to each index under the adjusted speed.

[0093] Exemplarily, the meteorological trend chart corresponding to the index of wind speed, the meteorological trend corresponding to the index of swell height, the meteorological trend corresponding to the index of wave height and the meteorological trend corresponding to the index of longitudinal flow speed can be seen from Figure 3 The abscissa of the meteorological trend chart represents the estimated arrival time, and the ordinate represents the specific value under the corresponding index.

[0094] In this embodiment, if it is determined according to the meteorological trend chart and the preset warning threshold that the warning meteorological data is obtained, the first station and the second station corresponding to the warning meteorological data are determined, the arrival time of the first station is earlier than the arrival time of the second station; the average speed is determined again or the stop time at the first station is determined, taking the first station as the starting point, to determine the safety attribute of the navigation route.

[0095] The preset early warning threshold is a red line value preset for safe driving of the target ship. For example, for the index wave height, the preset early warning threshold is 5 m, that is, the wave height higher than 5 m indicates that the target ship driving has a certain risk. According to the vertical coordinate value corresponding to each horizontal coordinate in the weather trend chart and the preset early warning threshold, it can be determined whether it is early warning weather data. Optionally, if the vertical coordinate values of the continuous multiple horizontal coordinates are greater than the preset early warning threshold, it indicates that the target ship driving in this time period has a driving risk.

[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 the vertical coordinate value of one or a preset number of the continuous multiple horizontal coordinates is greater than the preset early warning threshold, it still indicates that the target ship driving in this time period has a risk, and it can continue to be processed.

[0097] The predicted weather data higher than the preset early warning threshold in the weather trend chart is taken as early warning weather data. The starting and ending non-arrival station points associated with the early warning weather data can be determined. For example, the non-arrival station points corresponding to the early warning weather data are A1, A2 and A3. The arrival order is A1, A2 and A3 in turn, at this time, the starting non-arrival station point is A1 and the ending non-arrival station point is A3. Based on this, the first station point is A1 and the second station point is A2. The average speed can be determined again with the first station point A1 as the starting point or the stopover time at the first station point is determined, so as to determine the safety attribute of the navigation route based on the updated average speed or the stopover time at the first station point.

[0098] In this embodiment, after obtaining the predicted weather data of the estimated arrival time, the target report can be generated according to the predicted weather data of the estimated arrival time.

[0099] Optionally, the target report can include a report schematic diagram corresponding to each dimension. The report schematic diagram can refer to the result shown in Figure 3 .

[0100] The target report is generated based on the predicted weather data corresponding to the estimated arrival time.

[0101] It can be understood that for each adjusted speed, the trend schematic diagram corresponding to different weather dimensions, that is, the target report, can be determined. The steering user corresponding to the target ship can determine the driving safety of the target ship and whether to adjust the driving speed or driving plan of the target ship according to the report.

[0102] Of course, the scheme provided by the embodiment of the application can also be determined according to the trend chart, and the driving plan is mainly to adjust the sailing speed or the berthing time of the corresponding berthing point of the target ship, so as to control the target ship from the above two dimensions, thereby ensuring the effect of driving safety of the target ship.

[0103] The technical scheme provided by the embodiment of the application can determine the average sailing speed of the target ship in the remaining mileage according to the current position and the sailing route of the target ship during the driving process of the target ship, and then determine a plurality of adjusted speeds according to the average sailing speed and the preset sailing speed adjustment step. For each adjusted speed, the estimated arrival time of each unarrived berthing point can be determined according to the position data of the unarrived berthing point after the adjusted speed and the current position. At this time, the prediction meteorological data of the estimated arrival time can be obtained, and then the safety attribute of the sailing route can be determined according to the prediction meteorological data, thereby solving the problem that the safety of the ship driving along the route cannot be effectively determined in the prior art, resulting in driving risk. The prediction meteorological data of the sailing route can be dynamically determined, and then the safety of the target ship at the corresponding driving position is determined according to the prediction meteorological data, and the effect of adjusting the ship sailing information is determined according to the safety.

[0104] As an optional embodiment of the above embodiment, Figure 4 A schematic diagram of a route safety guarantee method provided by the embodiment of the application is shown in Figure 4 The implementation of the method mainly includes three parts, namely a data preprocessing part, a report generation part and a report export part.

[0105] The data processing part mainly includes loading the route, calculating the distance from the current ship position to each remaining route point, setting the calculation speed, the time of reaching each route point under different speeds and the route meteorological difference; the report generation part includes generating an encountered meteorological chart, generating a route meteorological profile chart, generating a different speed encountered sea state chart, report generation and report format conversion; the report export part includes uploading the report to the server, pushing the report email and storing the report address information.

[0106] Next, the specific content of each part will be introduced in detail.

[0107] First, load the route file, wherein the route file includes the route name, the latitude and longitude data of each to-be-arrived route point (berthing point) and the sailing time.

[0108] During the driving process of the target ship according to the route file, the safety attribute of the sailing route can be determined in real time, or the safety attribute of the sailing route can be determined periodically.

[0109] The remaining distance of the target ship to the remaining un-reached way point can be determined according to the current position and the sailing route of the target ship. Then, the average sailing speed can be determined according to the remaining distance.

[0110] Optionally, the remaining distance is calculated according to the current position:

[0111] wherein, is the total remaining distance, is the distance data of the current position to the next un-reached way point, is the distance information of the next un-reached way point to all the following way points.

[0112] The average sailing speed can be determined according to the remaining distance in the following ways:

[0113] wherein, is the average sailing speed of the remaining distance, is the remaining distance, is the final arrival time of the sailing route, is the current time.

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

[0115] After the at least one adjusted speed is obtained, the estimated arrival time of the target ship to the corresponding un-reached way point can be determined according to each adjusted speed and the sailing route. That is, for each adjusted speed, a set of estimated arrival times of the target ship to the corresponding un-reached way point can be obtained.

[0116] After the estimated arrival time of the target ship to the corresponding un-reached way point is obtained under different adjusted speeds, the latitude and longitude data of each un-reached way point can be obtained. According to the latitude and longitude data and the estimated arrival time of each un-reached way point, the predicted weather data of the target ship can be determined. That is, the predicted weather data of the target ship at each un-reached way point under each adjusted speed can be obtained.

[0117] After the predicted weather data of each un-reached way point is obtained, the predicted weather data of the un-reached way point can be interpolated according to the latitude and longitude data to obtain the predicted weather data on the sailing route of the target ship.

[0118] For different adjusted speeds, a sailing profile table can be generated. The sailing profile table can include the ship name of the target ship, the route, the current time, the remaining sailing time, the remaining distance, the average sailing speed, and the predicted weather data of different way points.
