In industries, particularly the construction field, the number of workers is decreasing because of the falling number of young new hires and the increasing number of existing elderly workers. Therefore, it is important to improve the productivity of each worker at a construction site. At many construction sites, operation and decision-making skills of construction machine operators are required, and work productivity depends on these skills of the operators. However, the number of elderly skilled operators is decreasing, and it is necessary to accurately train young unskilled operators to develop the aforementioned skills in order to improve productivity. Thus, a system that can quantitatively evaluate the operation skills of the operator is required. This study proposes a system that can quantitatively evaluate the operator's skills by using a database-driven technique. The proposed method is applied to the swing operation of a hydraulic excavator. Furthermore, skill evaluation is carried out by multiple operators, and the effectiveness of the proposed method is verified. © 2021 Institute of Electrical Engineers of Japan.

基于数据库驱动的液压挖掘机技能评价系统构建

在行业，特别是建筑领域，由于年轻新员工数量下降和现有老年工人数量增加，工人数量正在减少。因此，提高施工现场每个工人的生产力是很重要的。在许多建筑工地，需要建筑机械操作员的操作和决策技能，而工作效率取决于操作员的这些技能。然而，老年熟练操作者的数量正在减少，需要准确地培训年轻的非熟练操作者发展上述技能，以提高生产率。因此，需要能够定量评价操作者的操作技能的系统。本研究提出了一个可以定量评估操作员的系统。通过使用数据库驱动的技术来提高技能。将所提出的方法应用于液压挖掘机的回转作业。此外，由多个操作员进行技能评估，验证了所提出方法的有效性。© 2021 日本电气工程师学会。由 Wiley Periodicals LLC 出版。
