Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The invention provides a water navigation management planning method, as shown in fig. 1, comprising the following steps:
and 400, correspondingly displaying the navigation time of each road section in the first navigation path on the chart.
In particular, the specific parameters of the vessel generally include vessel type, vessel class, overall length, width, height, design draft, full displacement, no-load draft, no-load displacement, reference cargo displacement, total tons, net tons, main engine power, and main engine speed. The draft of the ship is calculated according to specific parameters of the ship and the weight of the carried goods of the starting place and the destination input by a crew, and a first navigation path capable of navigating is determined according to the draft of the ship and correspondingly marked on the chart. The route information is information on a route on which the ship navigates on water, and can comprise weather information, hydrologic information, geographic information, logistics information, personnel information, shipping information and the like, and the information can influence the passing-stopping port of the ship and the passing condition of the ship; after the corresponding route information is collected, the time period that the ship passes through the corresponding road section is determined according to the route information, the state of the water level on the first route is determined, and whether the draught of the ship can cause the ship to touch a reef or be stranded or not is judged, so that the optimal time period that the ship passes through the road section is determined, and the optimal sailing time for sailing is displayed on the chart.
As shown in fig. 2, the collecting of the route information corresponding to the first route and the calculating of the optimal time to navigate in the first route based on the route information further includes:
301, collecting weather information and hydrological information on a first airway according to the first airway, planning the transit time of the first airway according to the weather information, and avoiding a time period with severe weather in the first airway to obtain a first navigation time period;
and step 304, taking the second navigation time period as navigation time.
Particularly, as the overwater navigation condition is seriously influenced by weather, mainly the water level is influenced by weather and has rising possibility, and the water level also has tide, the ship can rise along with the rising of the water level when sailing on the sea due to certain draft, and the water level can inevitably pass through a bridge when sailing on the water; the first voyage period is a time period when the ship does not touch the bottom when sailing on the first voyage.
And collecting bridge information existing in the route of the first route, wherein the bridge information is generally the clear height of the bridge, predicting the time of reaching the corresponding bridge according to the running speed of the ship, and predicting the water level according to the weather and hydrological information (such as tide) at the moment to obtain the distance between the ship and the bridge. In practical applications, when a ship runs near a bridge, the highest point of the ship is lower than the bridge, otherwise collision occurs, that is, a margin height is required to be ensured when the ship passes through the bridge, and the margin height is the distance between the bridge and the highest point of the ship.
The margin height can be set according to actual needs, and is exemplified by the margin height being 2 meters, and when the margin height when the ship is expected to pass through the corresponding bridge is less than 2 meters, namely the distance from the highest point of the ship to the bridge is less than 2 meters, the time period is excluded; if the estimated surplus height of the ship passing through the corresponding bridge is more than 2 meters, namely the distance from the highest point of the ship to the bridge is more than 2 meters, the time period is reserved. And after the time period with the potential safety hazard during navigation is eliminated in the first navigation time period, the reserved first navigation time period is finally sorted into a second navigation time period.
The second navigation time period is arranged to be used as navigation time and is displayed on the chart; and finally, displaying the optimal time for each path on the first route to pass, namely the voyage time, on the chart.
In the actual navigation process, a ship can pass through a bridge, the condition of passing through a ship lock still exists, the ship is influenced by the navigation condition of the ship lock, the navigation scale of the ship lock can pass through the ship lock only when the ship needs to meet the navigation scale, and the navigation scale of the ship lock is a general term of a channel scale, an effective scale of the ship lock and a navigation clearance scale. The channel scale comprises channel water depth, channel width and channel bending radius, and the limit of the channel size on the ship is avoided in the first navigation period; the effective length, the effective width and the threshold depth of the ship lock are measured according to the effective size of the ship lock; the effective length of the ship lock is the length of the lock chamber for safely mooring the ship; the effective width of the ship lock refers to the width of the lock chamber for safely mooring the ship; the depth of the threshold water refers to the vertical distance from the designed lowest navigation water level to the top of the threshold. Generally, the effective length and the effective width of the ship lock do not limit the navigation of the ship, the depth of the threshold water is the vertical distance between the highest point of the ship with proper draft and the top of the threshold, and the depth of the threshold water also needs to meet the above-mentioned margin height when the ship is actually navigated, namely the vertical distance between the highest point of the ship and the top of the threshold is not less than the margin height; and screening the second navigation time period according to the surplus height, and eliminating the time period with the potential safety hazard of navigation to obtain a third navigation time period. The navigation clear dimension is a general term of the navigation clear height and width dimensions; the navigation clear height refers to the vertical distance from the lowest point of the bottom of the building beam to the designed highest navigation water level in the internal hollow range of the pier columns on two sides of the navigation hole of the building spanning the navigation channel; the clear width of navigation refers to the effective width for safe navigation of ships or fleets in the internal hollow range of piers on two sides of a navigation hole of a building crossing a channel. The navigation clear height is mainly considered, namely the distance between the lowest point of the beam bottom of the building and the highest point of the ship at the moment also needs to meet the margin height, and the vertical distance between the highest point of the ship and the lowest point of the beam bottom of the building is not less than the margin height; and screening the third navigation time period according to the surplus height, eliminating the time period with the potential safety hazard of navigation, and obtaining a fourth navigation time period. And finally outputting the fourth navigation time period as the navigation time.
Optionally, after step 400, the method for planning navigation management on water further comprises:
receiving radar signals, AIS base station signals, GPS signals and Beidou information;
and correspondingly displaying the position of a nearby ship, the position of a navigation mark and the position of the ship on the chart according to the radar signal, the AIS base station signal, the GPS signal and the Beidou information.
Specifically, when a ship navigates, AIS base station signals are received when the ship passes through a navigation mark or a bridge, and the AIS base station signals can be processed to display corresponding navigation mark positions on a chart; the near ship can detect a radar signal through a radar, the radar signal is processed and displayed on the chart, the distance and the navigation direction of the near ship can be observed, and collision with the near ship during navigation is avoided; according to the GPS system and the Beidou system of the ship, the GPS signal and the Beidou signal are received, and the position of the ship can be marked on the chart.
Further, after the step 400, the method for planning navigation management on water further comprises:
and determining the relative distance between the ship and the first route according to the GPS signal, and if the relative distance is greater than the preset distance, sending a prompt message of the current deviated route.
In practical application, the preset distance can be set according to actual needs, and the preset distance is 5 nautical miles, for example, as follows: when the ship navigates, if the relative distance between the ship and the first navigation path is determined to be not more than 5 nautical miles by the GPS signal, no prompt message is sent; and when the relative distance between the ship and the first airway is more than 5 nautical miles, sending corresponding prompt information, wherein the prompt information is that 'you deviate from the optimal airway and please adjust the course in time' and the prompt information is marked on the chart in a striking color, and meanwhile sending the prompt information to the crew mobile phone APP.
Optionally, after step 400, the method for planning navigation management on water further comprises:
sending the first route to a cloud end, and receiving the residual berth information of a wharf cabin near a destination returned by the cloud end;
and calculating the wharf cabin which is closest to the destination and suitable for berthing according to the information of the rest berths, and displaying the wharf cabin on the chart.
Specifically, the cloud end can be a shipping management enterprise such as a wharf and a shipping company, the shipping management enterprise obtains a destination of a ship according to the first route, correspondingly inquires a wharf cabin of a destination accessory, keeps real-time contact with the corresponding wharf cabin and receives the rest berth information;
the crew can know the remaining berth of the wharf cabin in real time, select a proper wharf cabin nearby to stop, reduce the ship stopping time and improve the working efficiency.
In practical application, the ship management enterprise can monitor the ship in real time according to the GPS signal and the Beidou signal of the ship and transmit instructions to the ship through the AIS signal, so that the ship management enterprise can manage the ship conveniently; when the ship passes through the bridge, the shipping management enterprise can also obtain the surplus height between the ship and the bridge and judge whether the ship collides with the bridge; if the ship is found to collide with the bridge, the ship management enterprise can send a warning to the ship, so that collision danger is effectively avoided.
According to the above method, system, computer device and storage medium for managing and planning navigation on water, the information of the departure place, the destination and the ship is obtained, and a plurality of navigable first navigation paths are calculated according to the information; collecting route information corresponding to a plurality of first routes, and excluding first routes which are not suitable for navigation; then, collecting the bridge information in the first residual route set to calculate the time of reaching the bridge, calculating the height difference between the ship and the bridge at the moment according to weather data corresponding to the time, eliminating the first routes with collision risks, selecting the first route with the shortest time consumption from the residual first routes as a second route, and displaying the second route on a chart; sending the second route to the cloud end, receiving the returned berth information, and displaying the berth information on the chart; when the ship deviates from the airway by a certain distance, sending an information prompt of the deviated airway; the method for planning the navigation management on the water plans the route through the route information, can reduce risks brought by manual planning, facilitates the ship to quickly arrive at a destination, and improves the management efficiency and the working efficiency of shipping.
