摘　　要：为研究适应于大规模智能电能表自动化检定的关键技术,从数据交互、调度控制、智能诊断3个方面对离散型检定模式进行探讨。首先,从多维感知角度构建自动化检定数据的应用架构,采用WCF(windows communication foundation)和MQ(active message queue)通信模式搭建数据交互架构,提出前馈反馈综合控制机制;其次,基于自动化检定的控制架构,建立时空纵横调度控制策略;最后,依据自动化检定设备类别划分异常/故障类别并建立故障知识库,基于"告警-发现-诊断-处理-学习"机制的智能诊断流程,搭建智能诊断应用架构。所提方法有效保证了交互数据的准确和可靠,实现了自动化检定的时空协同运行,能够有效提高大规模自动化检定日常运维效率。Key technologies of large-scale automated verification of smart meters are dicussed from data interaction, dispatching control and intelligent diagnosis. First, an application architecture of discrete automatic test is built from multi-dimensional sense using WCF （Windows Communication Foundation） and MQ （Active Message Queue） communication mode. A method combined with feedforward and feedback control is proposed to ensure accuracy and reliability of interactive data. Second, time-space dispatching control strategy is constructed based on the automation verification control framework. Third, combined with fault-knowledge library, ＂Alarm- Discovery-Diagnosis-Resolution-Study＂ method is used to construct intelligent diagnosis. The proposed methods are effective for accurate and reliabile data interaction, cooperation of automatic test and operational efficiency.
