Problems solved by technology
The system is mainly a passive warning for ships. For ships that meet navigation requirements or for small ships, passive warning will cause too much information interference or inaccurate misleading information.
On the one hand, the early warning information is only the navigation clearance scale and is a real-time early warning that cannot be used for short-term prediction. On the other hand, there is no visual and effective verification function of large screens and pouring rulers when navigating in the bridge area

Embodiment approach
[0036] As an implementation, the method further includes: when the ship arrives in the early warning area, automatically push the warning area arrival reminder to remind the current ship to drive cautiously, strengthen the lookout, and actively check the navigation information of the bridge area displayed in the short range. By pushing the arrival reminder of the early warning area, the ship driver can check the short-range navigation information displayed in the bridge area waters early, and further check with the remote active query navigation information, so that the ship driver can grasp the bridge area waters to be passed in a longer period of time. The change of navigation information over a period of time provides reliable information support for it to safely pass through the waters of the bridge area. Compared with the way in the prior art that the navigation information is only displayed through the inverted water gauge or the warning information is issued through the ...

The invention discloses an early warning method for ship navigation in the water area of the bridge area, which includes: collecting and uploading the water level and water flow information of the water area of the bridge area; processing the water level and water flow information to generate navigation information of the water area of the bridge area; Near-distance display and remote upload of the navigation information of the water area of the bridge area; active query of the navigation information of the water area of the bridge area uploaded remotely. The invention actively understands and grasps the navigation information of the bridge by the ship itself, realizes the early warning of the navigation information through the "short-range direct display + remote active query", and then effectively reminds the ship driver to make a reasonable judgment in advance, so as to reduce the damage of the bridge by the ship chance of damaging accidents.
Description
technical field [0001] The invention relates to the technical field of navigation aids for ships in bridge area waters, in particular to a navigation early warning method for ships in bridge area waters in inland rivers. Background technique [0002] my country's inland river shipping is well developed, and the cross-water bridge, as an important hub connecting the two sides of the river, plays an important role in the development of the transportation industry. In recent years, the number of cross-water bridges has also increased year by year. According to statistics, as of October 2019, a total of 96 bridges have been built or are under construction on the Yangtze River, of which 21 are in Chongqing urban area, 11 in Wuhan urban area, and 11 in Nanjing urban area. There are 9 seats. At the same time, bridges have also brought many constraints to ship navigation. In recent years, ship damage and bridge damage accidents have occurred frequently due to underestimation of the...
