Anti-collision system for group of tower cranes based on embedded Linux

为提高施工效率,在同一建筑施工现场经常需要同时布置多台近距离交叉作业的塔机,这些塔机之间存在碰撞可能,因此塔机群防碰撞系统的研究具有重要意义。讨论了基于嵌入式Linux塔机群防碰撞控制系统的实现方案,设计了基于AT91RM9200嵌入式微控制器的监控仪表主机,完成了塔机工作状态的实时检测,如重力、力矩、幅度、高度、回转角度及风速等,利用无线通信技术实现了相关塔机状态信息的交互,依靠防碰撞算法,控制塔机输出,达到预防塔机碰撞的作用。研究结果表明,该方案具有处理能力强、实时性强、人机交互友善等优点。

In order to improve efficiency,it always needs to set up several cross cranes in small quarters,and this causes collision possibility between these cranes,so the study of tower crane anti-collision system is very important.Based on the embedded Linux,the program of tower crane anti-collision system was discussed.Then,based on AT91RM9200,an embedded microprocessor,a monitoring instrumentation host was designed,and real-time detection of every crane＇s working status was realized,such as gravity,torque,range,height,rotation angle and wind speed,etc..Then,the interaction of correlated cranes＇ operating status information using wireless transmission was realized.Depending on the algorithm of anti-collision,the system controlled the output of cranes to achieve the goal of preventing the collision of cranes.The results indicate that this program has the advantages of strong processing ability,strong real-time ability,and friendly user interface,etc..
