【摘要】：现代物流业的快速发展,集装箱起重机越来越追求效率。因为船舶的集装箱堆叠错落有致,高低不整,在吊装船舶上位于中间的集装箱稍有不慎就会撞到旁边的集装箱,并可能导致严重的安全事故。此外,岸桥小车的运行速度本身就非常快,司机在驾驶室观测吊具下方吊装的集装箱位置不是很敏感。因此,为了安全起见,司机在吊装过程中,往往会把起升高度拉的非常高,吊具处于远远高于集装箱上方的正常高度。但这种过度起升的运行轨迹,往往增加不必要的起升高度,导致装卸时间大幅增加,效率显著下降,不仅增加起重机能耗,同时也减少钢丝绳寿命和增加机械磨损。另外,由于对高度不敏感,在吊装过程中,提箱和着箱过程中由于速度快,会带来很多的冲击,损坏集装箱和车辆,也可能由于钢丝绳过度送放带来钢丝绳损伤。为了解决上述问题,本文利用PLC技术、网络通讯技术、传感器技术、HMI技术等研发了一种岸线集装箱起重机装卸监控系统。该系统利用两个激光测距仪对集装箱桥吊下面船舶甲板上的集装箱堆放情况进行实时监测,再利用工业控制用PLC通过合理编程对激光测距仪传回的数据进行及时有效的处理,将这些处理过的数据与岸桥本身的起升和小车绝对值编码器提供的信息相结合,实现对起升和小车动作安全高效的控制。该系统还可以利用不同激光传感器和设备本身自有的传感器之间位置数据的实时比对,实现系统自身的自纠错功能,从而确保系统本身的安全性和可靠性。
[Abstract]:With the rapid development of modern logistics industry, container cranes are becoming more and more efficient because the container stacking of ships is fragmented and uneven. The container in the middle of the hoisting ship may collide with the next container, which may lead to serious safety accidents. In addition, the speed of the quayside trolley itself is very fast. It is not very sensitive for the driver to observe the container position under the hoist in the cab. Therefore, for the sake of safety, the driver will often pull the hoisting height very high in the course of hoisting. The hoist is far higher than the normal height above the container, but this excessive lifting track often increases the unnecessary lifting height, resulting in a large increase in loading and unloading time and a significant decrease in efficiency. Not only increase the energy consumption of crane, but also reduce the life of wire rope and increase mechanical wear. In addition, because of the insensitivity to height, in the process of hoisting, there will be a lot of impact in the process of hoisting and handling. Damage to containers and vehicles may also be caused by excessive wire rope wire rope damage. In order to solve the above problems, this paper uses PLC technology, network communication technology, sensor technology. HMI has developed a kind of container crane loading and unloading monitoring system, which uses two laser rangefinders to monitor the container stacking on the ship deck under the container crane in real time. Then the data from the laser rangefinder are processed in a timely and effective manner by using industrial control PLC through reasonable programming. The processed data is combined with the information provided by the lift of the shore bridge itself and the absolute value encoder of the car. The system can also make use of the real-time comparison of position data between different laser sensors and their own sensors to realize the self-correcting function of the system. To ensure the security and reliability of the system itself.
