Inland river bridge area ship safe navigation precontrol system

Abstract

The invention relates to an inland river bridge area ship safe navigation precontrol system which comprises a radar station, an information processing center and an AIS base station. The radar station and the AIS base station are respectively in communication connection with the information processing center. The information processing center comprises a data processing and recording unit, a track fusion unit, an electronic river map unit, a precontrol decision-making unit and a precontrol information sending unit, wherein the data processing and recording unit obtains data from the radar station or / and the AIS base station and processes and records the data, the track fusion unit carries out fusion on the obtained radar or / and AIS data to obtain ship tracks, the precontrol decision-making unit carries out prediction according to the data processed and recorded by the data processing and recording unit and judges whether alarm instructions are sent out or not, and the precontrol information sending unit controls the AIS base station to send out alarms according to the instructions sent out by the precontrol decision-making unit. According to real-time traffic situations, the inland river bridge area ship safe navigation precontrol system can automatically identify navigation risks of the ships, automatically carry out early warning on the ships, guide the ships to pass through a bridge area safely, and reduce accident risks.

Description

technical field [0001] The patent of the present invention relates to a safety warning and control system for water vessel traffic at the shore base, in particular to an automatic pre-control system for vessel navigation in inland river bridge areas. Background technique [0002] With the rapid development of the transportation industry, the number of inland river bridges has increased year by year. The construction of these bridges has undoubtedly promoted economic development, but it has also deteriorated the navigation environment of the bridge area to a certain extent, especially in busy waters with many ships. , Bridges hinder the navigation of ships, increase the difficulty of navigation, and increase the risk of accidents such as ship grounding, ship collision, and bridge collision. Once an accident occurs, it will cause loss of life and property, and some will cause environmental pollution. At present, there are generally two ways to reduce these risks: first, the sh...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a pre-control system for safe navigation of ships in the inland bridge area in view of the defects that the existing technology cannot automatically identify the navigation risk of the ship in the water area of ​​the bridge area and carry out early warning and control of the ship. Real-time traffic conditions in the bridge area, automatic identification of ship navigation risks and automatic early warning of ships, guide ships to pass through the bridge area safely, and reduce the risk of accidents
