The interface was designed to help the remote supervisor to instruct the autonomous sprayer to commence operation, monitor the status of the sprayer and its operation in the field, and intervene when needed (i.e., to stop or shut down). Design principles and guidelines were carefully selected to help develop a human-centered automation interface. Evaluation of the interface using a combination of heuristic, cognitive walkthrough, and user testing techniques revealed several strengths of the design as well as areas that needed further improvement. Overall, this paper provides guidelines that will assist other researchers to develop an ergonomic user interface for a fully autonomous agricultural machine.展开更多
10 kV分线线损率异常原因多样,分析排查手段有局限性。通过变电站、线路和台区三个区段之间的数据采集与监视(Supervisory Control And Data Acquisition, SCADA)、电能量采集和用电信息采集等多系统交互,提出两种10 kV电缆线路线损率...10 kV分线线损率异常原因多样,分析排查手段有局限性。通过变电站、线路和台区三个区段之间的数据采集与监视(Supervisory Control And Data Acquisition, SCADA)、电能量采集和用电信息采集等多系统交互,提出两种10 kV电缆线路线损率异常分析方法。该两种方法作为排查手段,分别在未配置和已配置配电网自动化的情形下实现,在同期线损计算“T+2”的原则下可相互配合。所提方法在提升线路合理率的同时,有效缩短分析时长,提高分析效率。最后以案例实施验证了两种方法的有效性。展开更多
