It's important for the staff who investigate an accident to be the person who became independent from a production site. Moreover a special right has to be granted to the staff in the organization. The reason is because it's necessary that they have a different viewpoint from field overseer. The staff's viewpoint is a one related to the importance of the site preservation,necessity of an information feedback and the way to fill out an accident report. It was modeled in the last chapter about a relation of the various factors which have an influence on accident investigation.展开更多

Working parties must act together to make these safety tools effective. To get the staff units to work together in a co-ordinated manner, they must be shown the value of their work in preventing accidents. Examples of actual accidents investigated during the author's 18 years as a mine inspector in Saskatchewan are discussed within the context of pre-job safety analyses. The causes of the accidents are explored with close reference to how pre-job safety analyses could have prevented their occurrence.展开更多

在低亮度条件下,传统的事故勘察方法难以获取高质量的勘察数据。提出了基于机载激光雷达的低照度事故现场重建方法。首先,建立机载激光雷达勘察的方法框架。接着,使用高斯分布的统计学滤波算法去除噪点,通过判断空间划分体素的占据状态...在低亮度条件下,传统的事故勘察方法难以获取高质量的勘察数据。提出了基于机载激光雷达的低照度事故现场重建方法。首先,建立机载激光雷达勘察的方法框架。接着,使用高斯分布的统计学滤波算法去除噪点,通过判断空间划分体素的占据状态来滤除现场周围移动物体。然后,利用传感器自身的位姿数据配准点云数据,建立事故现场的三维点云模型。此外,探究了无人机飞行高度和激光旁向重叠率如何影响建模精度。最后,在夜间模拟事故现场进行实证研究,研究发现当无人机飞行高度为15 m,激光旁向重叠率为50%时,建模精度和处理时间能达到较好平衡。与航拍摄影建模、传统人工勘察方法相比,机载激光雷达建模均方根误差(root mean square error,RMSE)为0.04636,低于航拍摄影建模误差,表明方法能够应用于低照度交通事故现场勘测。展开更多
文摘The way to investigate the cause of an industrial accident is considered. It's important for the staff who investigate an accident to be the person who became independent from a production site.
