船舶抗沉辅助决策系统的研究与设计

抗沉辅助决策系统是船舶常规和紧急状态下进行损管行动的关键性依据。目前抗沉计算分析系统,可对船舶基础状态、浮稳性等信息进行管理,并进行仿真和辅助决策,但大多存在算法效率低,决策生成速度和精度不足、人机交互接口脱离实际等问题。本文从船舶抗沉操作的实际执行过程出发,制定抗沉算法,根据实时装载和破损情况,对液舱采用注入水或排水的损管操作,生成调整措施,使船舶恢复良好的浮态与稳性。系统基于面向对象过程控制平台设计和实现,仿真结果验证了系统的有效性和高效性。

Research and Design of Watercraft Anti-sinking Assistant Decision System

A high-performance anti-sinking assistant decision system serves as a pivot for watercraft commander to make exact decisions and carry out effective measures as quickly as possible when adjustments are need.Assistant decision systems nowadays can help to supervise the basic navigation information and control the floating states,but most of these systems suffer the following limitations： System architectures are too simple to implement a large-scale process control;Inefficient system＇s algorithm decreases the rapidity and precision of decisions generating;System＇s HMI（human machine interface） is always ivory-towered that greatly reduces the practicability of system.The innovative anti-sinking assistant decision system implements a rapid iterative algorithm which takes the equilibrium parameter as the optimization target-value.This paper develops the system on an object-oriented SCADA platform with Windows component object module（COM） which offers high performance and practicability.It has been improved very efficient by a series of given examples of simulation of ship floating.
