无人天车防撞系统的研发

Research and Development of Unmanned Crane Anti-collision System

本文主要介绍了无人天车防撞系统的研发,包括硬件构成、通讯、手动防撞、自动防撞。自动防撞功能细分为一级防撞功能、二级防撞功能、地面站防撞功能。防撞功能基于PLC实现,两车间的实时距离与每部天车在库区中的实时位置依靠激光测距传感器测量,天车PLC采集激光测距传感器的数值,经过程序计算并转化成实际的距离。系统的研发能够有效避免无人天车在任意状态时发生相撞事故,保障天车以及现场人员的安全。

This paper mainly introduces the research and development of unmanned crane anti-collision system,including hardware composition,communication,manual anti-collision,automatic anti-collision.Automatic anti-collision function is subdivided into primary anti-collision function,secondary anti-collision function,ground station anti-collision function.The anti-collision function is realized based on PLC.The real-time distance of the two workshops and the real-time position of each crane in the storage area are measured by the laser range fi nder.The PLC of the crane collects the value of the laser range fi nder,which is calculated by the program and converted into the actual distance.The research and development of the system can eff ectively avoid the collision accident of the unmanned crane in any state and guarantee the safety of the crane and the personnel on site.
