摘要
针对自动引导车(AGV)在自动化码头水平运输过程中可能发生的路径冲突问题,提出一种将AGV路径容量、安全距离、行驶时间及行驶速度相结合的多参数优化控制模型.Dijkstra算法规划多条AGV路径,位向量交集运算法检测路径冲突,改进的速度控制策略通过控制AGV在冲突节点处的行驶速度,解决冲突问题.对某自动化码头的AGV路网进行仿真实验和分析.比较停车策略、速度控制策略和改进的速度控制策略的结果,验证了改进速度控制策略在AGV路径冲突问题中的可行性及有效性.
To solve the path conflicts for an Automatic Guided Vehicle（AGV） that may occur in the horizontal transportation of automated container terminal,a control strategy is proposed with multiparameter include path capacity,safety distance,travel time and vehicle speed.Dijkstra algorithm is used to plan path.A bit vector intersection algorithm is used to detect collisions.The improved speed control strategy is proposed to solve the path conflicts by controlling the traveling speed of the AGV at the conflict nodes.By simulating and analyzing the AGV network of Yangshan fourth automated container terminal,compare the traditional stop waiting strategy,the speed control strategy and the improved speed control strategy.The results verify the feasibility and effectiveness of the improved speed control strategy in conflict solving.
