摘要
车地无线网络高速稳定是保障井下机车智能运输系统安全高效运行的关键。以中关铁矿井下电机车无人驾驶智能运输系统为背景,提出井下电机车在高速运行下车地无线网络技术解决方案。在对巷道AP布点及无缝覆盖技术、信号冗余覆盖技术、RF射频衰减技术、防电磁抗干扰技术、网络管理技术等进行综合分析的基础上,提出总体网络架构、巷道AP布点方案、安装技术要点及详细的信号抗干扰技术措施,实现实时无缝地完成车地间图像和控制信号的双向传递,确保地表控制中心与机车之间建立稳定、安全且能避免冲突的通信网络,在地表控制中心实现对井下主干网和车地无线网的管理和控制。
The high-speed stability of train-ground wireless network is the key to ensure the safe and efficient operation of underground locomotive intelligent transportation system. Based on the unmanned intelligent transportation system of underground electric locomotive in Zhongguan Iron Mine,the wireless network technology solution of underground electric locomotive under high speed operation is proposed. Based on the comprehensive analysis of roadway AP distribution and seamless coverage technology,signal redundancy coverage technology,RF radio frequency attenuation technology,anti-electromagnetic anti-interference technology,network management technology,etc.,the overall network architecture,roadway AP distribution scheme,installation technical points and detailed signal anti-interference technical measures are proposed to realize real-time and seamless two-way transmission of images and control signals between trains and ground. To ensure that a,stable,safe and conflict-free communication network is established between the surface control center and the locomotive,and the management and control of the underground backbone network and the train-ground wireless network are realized in the surface control center.
