基于无线通信的养路机械施工人员防碰撞技术研究

针对大型养路机械作业时可能会碰撞周围施工人员的问题,对该工况下的施工人员防碰撞技术进行了研究。一方面提出了新的定位算法,该算法先采用无线通信测距技术获得了目标到基站的距离数据,然后利用双曲线与圆的几何特性得到了目标的定位结果;另一方面根据定位结果建立了施工人员的安全判断模型,该模型可以用于有效判断施工人员的安全状态。仿真结果表明,该定位算法精度较高,安全模型简单有效。

Anti-collision of maintenance machinery construction workers based on wireless communication technology

Aiming at the problem that it may collide when construction workers are around the large track maintenance machinery, the anti-collision technology for construction workers was studied. A new positioning algorithm was proposed and the wireless communication ranging techniques were used to obtain objective data from the base station, then the theory of the intersection between the circle and hyperbolic was used to get position effectively. A security model of construction workers was built based on position data. This model can be used to determine the security status of construction workers effectively. The results indicate that, the positioning algorithm is high precision and the security model is simple and effective.
