对自动寻迹运输车的控制方式和运行轨迹进行分析研究,提出系统总体设计方案。采用三菱公司的FX-2N可编程控制器为控制核心,以触摸屏为人机对话窗口,利用光电传感器检测行驶路线、运行速度和障碍物等信息,通过PLC编程控制,实现无人驾驶、自动寻迹、自动避障、自动变轨等功能。介绍系统硬件设计和软件设计。研制样机经实验室模拟调试和运行测试证明,操作简便,运行平稳,性能可靠。可应用于大型生产线、现代化工厂车间的物料运输。
This paper analyzes and studies the control mode and running track of the automatic tracing truck, and proposes the overall system design plan. Using Mitsubishi’s FX-2N programmable controller as the control core, the touch screen as the man-machine dialogue window, the use of photoelectric sensors to detect driving routes, speed and obstacles and other information through the PLC programming control, to achieve unmanned, auto-trace , Automatic obstacle avoidance, automatic orbit and other functions. Describe the system hardware design and software design. Development of prototype by the laboratory simulation test and run the test proved that simple, stable operation, reliable performance. Can be applied to large-scale production lines, modern factory workshop material transport.
