摘要
在开展桥梁超高防撞自动预警时,通信延迟现象会直接影响预警方法的预警效果,从而威胁船只的安全运行,为此提出考虑通信延迟的桥梁防撞自动预警方法。具体分析防撞预警的影响因素,基于分析结果建立通信延迟模型计算出数据预警通信时的探测时延,根据计算结果,在考虑通信延迟的情况下完成采集数据;再根据采集的数据确定防撞预警准则,获取隶属度函数以及相关约束条件;结合模糊神经网络建立桥梁的防撞预警模型,依据该模型完成桥梁的防撞自动预警。实验结果表明,使用该方法开展防撞预警,预警效果较好。
When carrying out bridge super-high collision avoidance automatic early warning,communication delay directly affects the early warning effect of early warning methods,thus threatening the safe operation of ships.Therefore,a bridge collision avoidance automatic early warning method considering communication delay is proposed.It specifically analyzes the impact factors of anti-collision warning,establishes a communication delay model based on the analysis results,calculates the detection delay of data warning communication,and completes the data collection considering the communication delay according to the calculation results.Then,according to the collected data,the anti-collision warning criteria are determined,and the membership function and related constraints are obtained.Combined with fuzzy neural network,a bridge collision avoidance early warning model is established,and according to this model,the bridge collision avoidance automatic early warning is completed.The experimental results show that the method is effective in collision avoidance warning.
