【摘要】 针对塔吊作业防碰撞问题,设计了用于障碍物检测的防碰撞探测器。基于超声波测距原理,探测器可以对接近塔吊臂的障碍物主动检测,发出报警信息。从系统的构成、工作方式、探测器结构设计和安装布置等几方面进行了详细论述,通过Matlab仿真对设计结果进行了验证。该设计扩宽了探测器检测范围,通过多节点布置,对塔吊臂形成了封闭的三维保护区,有效避免事故发生,对于塔吊安全运行具有重要意义。更多还原

【Abstract】 Aiming at problem of tower crane anti-collision,a detector for obstacle detection is designed. Based on principle of ultrasonic distance measurement,detector can automatically detect obstacles close to tower crane arm and send alarm message. System composition,operation mode,detector structure design and installation are illustrated indetail,design result is verified by Matlab simulation. The design broadens detection range,and closed three-dimensional protection zone around tower crane arm is formed through multiple nodes arrangement,that avoids accident effectively and it is of great significance for safe operation of tower crane.更多还原
