Safety early warning equipment for ship navigation in bridge waters based on rendezvous photography

Abstract

The invention belongs to vessel traffic management equipment, and particularly relates to convergent photography-based ship navigation safety early-warning equipment for ships in water area of bridges. The convergent photography-based ship navigation safety early-warning equipment comprises a detector, a computer system, a display device and an AIS (automatic identification system); the detector comprises a plurality of infrared thermal imagers which form a convergent photography measuring system; the sequence image collected by the detector is processed and calculated by the computer system, so that ships need to be early warned are found; the display device comprises an equipment sending AIS warning information to ships with collision risks, and directly warning vessel sailing personnel; and the AIS equipment is used for acquiring the AIS information of ships with the collision risks, discovered in the convergent photography measuring system. According to the infrared image and AIS-monitored-based ship navigation safety early warning equipment and system, the early warning on the ship-bridge collision accidents can be realized, and the purpose of nipping in the bud is achieved.

Description

technical field [0001] The invention belongs to ship traffic management equipment, in particular to a bridge water area ship navigation safety early warning and collision avoidance device based on rendezvous photography. Background technique [0002] The international research on the safety of ship navigation in the bridge area began in the 1960s. At the beginning, the progress was slow, the research field was small, and it did not receive widespread attention. In 1980, the Sunshine Bridge in the United States was collided by a bulk carrier, causing 35 deaths and direct economic losses of more than 250 million US dollars. The accident aroused the attention of all walks of life to the safety of bridges across navigable waters, and many countries have started to develop this aspect one after another. The research and exploration of this aspect have brought the research into a new era. [0003] In 1983, the International Association of Bridge and Structural Engineering (IABSE)...

AI Technical Summary

Problems solved by technology

[0011] Although AIS / VTS has played an extremely important role in water traffic safety, its role is limited to a certain extent. First, the installation, operation and maintenance of the VTS monitoring system requires a lot of funds. At present, my country only builds it on the coast and on the main line of the Yangtze River. VTS system, the navigation conditions of ships around other bridges in inland waters cannot be monitored by VTS; second, AIS / VTS cannot monitor the height of ships, and cannot give early warning to ships or people on board due to super-high collisions with bridges; third, AIS / VTS Although it can provide early warning for ships deviating from the route, the control accuracy is limited by the radar accuracy, which is roughly 20 meters to 40 meters, which cannot meet the requirements for preventing ship bridge collision accidents

[0012] To sum up, in terms of the ability to actively prevent accidents, both navigation beacons and AIS / VTS systems have great defects, and it is difficult to warn of ship collision accidents. Therefore, with the help of high technology, a targeted and capable The navigation and navigation aid system that realizes automatic early warning is of great significance to improve the safety factor of navigation in the bridge area and reduce the accident rate
