基于实时位置和速度的自动化轨道式龙门起重机防撞系统设计

Design of Anti-collision System of Automatic Rail-mounted Gantry Crane Based on Real-time Position and Speed

为了实现自动化堆场内轨道式龙门起重机安全而高效的运行,添加中转PLC实现堆场内2台轨道式龙门起重机的位置和速度信息交换,通过轨道式龙门起重机本机及相邻大车的位置识别和速度控制,在1台静止1台运行、同向运行和相向运行3种工况下,实现防撞控制,并通过优化提升了停止精度和运行效率,满足自动化堆场的应用需求。

In order to realize the safe and efficient operation of the rail mounted gantry crane in the automatic yard,the position and speed information exchange of the two rail mounted gantry cranes in the yard is realized by adding transit PLC.Through the position identification and speed control of the rail mounted gantry crane and adjacent big trucks,the anticollision control is realized under three working conditions of one static,one directional and one directional operation. The stop precision and operation efficiency are improved through optimization to meet the application requirements of the automatic yard.
