摘要
针对基于LKJ的机车辅助驾驶系统,分析了行程规划的功能需求,设计并实现了多进程协同处理的行程规划在线计算方案,重点阐述了行程规划的数据准备和数据处理过程,提出了基于速度控制模型和列车动态模型的周期迭代计算方法。经过测试,该方案可实现辅助驾驶行程规划功能,且能够在不影响列车运行控制功能的前提下动态计算规划曲线,满足行程规划的显示要求,为货运列车的平稳、高效、正点、节能运行提供保障。
Aiming at the LKJ-based locomotive assistant driving system,the functional requirements of train operation planning are analyzed,a multi-process collaborative processing online calculation scheme is designed and realized,the data preparation and data processing process of train operation planning are described in detail,and a periodic iteration calculation method based on speed control model and train dynamic model is proposed.Through testing,the scheme can realize the planning function of assistant driving operation,and can dynamically calculate the planning curve without affecting the train operation control function,meet the display requirements of operation planning,and provide guarantee for the smooth,efficient,punctual and energy-saving operation of freight trains.
