Intelligent berthing auxiliary system

Abstract

The invention relates to an intelligent berthing auxiliary system. The safety problem in the berthing process of large ships is solved mainly through the comprehensive applying of the advanced sensor technology, the communication technology, the computer technology, the network technology and the electronic technology. By means of the intelligent berthing auxiliary system, advanced intelligent equipment is introduced into the berthing operation of the large ships, the ships can be monitored in a real-time and quantization mode in the berthing process,, the operation mode that originally, berthing only depends on the experience of piloting workers in the field, the safe operation level is improved, the production and management information level of port enterprises are improved, and meanwhile production operation efficiency is improved.

Description

technical field [0001] The invention belongs to the field of ship berthing, in particular to an intelligent berthing auxiliary system. Background technique [0002] Ports generally use sonar, radar, and air-acoustic berthing technologies, but these technologies have inherent deficiencies that cannot be overcome, and cannot provide sufficient security protection for large ships to berth, so they have not been widely used. Due to the limitation of the constraint angle of the transducer in sonar berthing technology, when the operating distance is about 200m, its signal will be affected by water surface waves or underwater reflection waves, and the measurement accuracy and dynamic response speed of the system will be affected and decreased. Because radar berthing technology is easily affected by obstacles, rain, snow and other weather factors, its accuracy and operating distance will be limited. Only when it is within 50m, its accuracy will be improved, but it still cannot achie...

Problems solved by technology

[0002] Ports generally use sonar, radar, and air-acoustic berthing technologies, but these technologies have inherent deficiencies that cannot be overcome, and cannot provide sufficient security protection for large ships berthing, so they have not been widely used

Due to the limitation of the constraint angle of the transducer for sonar berthing technology, when the operating distance is about 200m, its signal will be affected by water surface waves or underwater reflection waves, and the measurement accuracy and dynamic response speed of the system will be affected and decreased.

Because radar berthing technology is easily affected by obstacles, rain, snow and other weather factors, its accuracy and operating distance will be limited. Only when it is within 50m, its accuracy will be improved, but it still cannot achieve a more ideal application Effect

Under ideal conditions, the effective working distance of air acoustic wave detection technology does not exceed 100m. Under windy conditions, its working distance, stability and accuracy will be significantly reduced. In addition, its response speed is slow, and it cannot meet the requirements of rapid feedback.

[0003] Laser detection technology has relatively ideal detection capabilities. Its beam energy is concentrated, its measurement accuracy is high, and its anti-interference ability is strong. The berthing system based on laser detection technology is generally limited to the research and development of single detection equipment, and it is still unable to achieve remote and intelligent The degree of modernization has not been widely applied in port enterprises at present
