A vessel management expert system

A unified collision avoidance system is proposed to improve the efficiency and safety of marine transport, namely maritime avoidance navigation, totally integrated system (MANTIS). The principle behind its operation is to remove the difficulties and uncertainties involved in marine navigation through a system structure that makes marine transport deterministic rather than uncertain. Fundamental to its operation is a strategic interactive expert system that can determine safe and efficient navigation routes for all vessels as part of journey planning and en route collision avoidance. An important requirement is to take account of non-navigable areas, collision regulations, ship characteristics, sea state and sensor accuracy during evaluation. An outline of the MANTIS infrastructure is given, followed by a description of the vessel management system (VMES). Simulation results exemplify the significance of the system for future exploitation.

The Difference

The difference between Traffic Alert and Collision Avoidance System and Automatic Dependent Surveillance Broadcast surveillance principle was compared. A TCAS/ ADS-B integrated surveillance system based on the present statistical model was built. Using the data fusion algorithm, the optimal local track of TCAS and ADS-B ,as well as the optimal fused track of the integrated system were estimated. The simulation results show that the maximum optimal fused estimated position error is 100m, it is certificated that the integrated system can improve track estimates accuracy, improve the surveillance precision of TCAS.

Path Planning Algorithm

In this paper, a collision avoidance system is proposed to steer away from a leading target vehicle and other surrounding obstacles. A virtual target lane is generated based on an object map resulted from perception module. The virtual target lane is used by a path planning algorithm for an evasive steering maneuver. A geometric method which is computationally fast for real-time implementations is employed. The algorithm is tested in real-time and the simulation results suggest the effectiveness of the system in avoiding collision with not only the leading target vehicle but also other surrounding obstacles.

in view of the current situation of ship has collision with sea mountain , design and develop the sonar of ship collision avoidance system based on PLC.its main purpose is to remind the crew in front of mountains and ship automatic collision avoidance. The design is based on the minimum distance of ship and mountain, put forward the system scheme: measure the two objects distance by sonar , using this system as the control core , the information is analyzed and calculated by this system. When the distance between ship and mountains is less than the minimum safe distance.so this system will alarm crews and as deceleration avoidance .

The paper is mainly concerned with the principles used by TCAS (Traffic alert and Collision Avoidance System) to resolve conflicts between airborne aircraft. It leans heavily on an earlier paper which describes the threat-detection process. The simulation results given were obtained using a fast-time computer model for random traffic and comprise statistics on miss distance, warning time, etc., for a simple traffic pattern.
