Abstract: To avoid conflict incurring in airport taxiway and ease air traffic controller load, a control strategy of taxiway conflict based on sensor network was proposed. The dynamic model of taxiway based on sensor network was proposed according to taxiway movement process and the taxiway movement controlling regulations are defined, then the problems of taxiway conflict are transformed into state forbidden problems. Controllers were designed using the partial correlation matrix method and logical mutual exclusion method for state forbidden problems, and a way is proposed for control command of lights decided based on the state of transition. Taxiway conflict can be avoided and guided automatically using navigation light. A simulation was provided to testify the effectiveness of the control strategy finally.

Key words: taxiway conflict, sensor network, Petri net, controller designing, navigation light

摘要： 为避免机场滑行道发生冲突，减轻管制员负荷，提出一种基于传感器网络的滑行道冲突控制策略.根据滑行道运行过程，利用Petri网建立传感器网络条件下的滑行道动态模型,并定义了滑行道运行控制规范,将滑行道冲突避免问题转化为状态禁止问题。针对状态禁止问题利用局部关联矩阵方法和逻辑互斥方法设计控制器，并提出基于变迁使能状态决策灯光控制指令的方法，利用助航灯光实现滑行道冲突避免和自动引导。最后通过实验仿真验证控制策略的有效性。
