摘　　要：为实现电能表错接线的实时监测,设计基于ZigBee无线传感器网络的电能表错接线自动化感知诊断系统。传感器节点实时采集电能表数据,利用经验模态分解方法去除存在于数据中的噪声,依据这些数据,通过DS证据理论对电能表错接线实施感知,当感知到电能表存在接线错误时,边缘端服务器立即做出响应,将感知结果及预处理后的电能表数据及时发送给云端;云端服务器接收到来自边缘端的信息后,利用支持向量机实现对电能表错接线自动化诊断。实验表明,该系统具备精准感知与诊断电能表错接线的能力,AUC值可达0.92以上。To achieve real-time monitoring of incorrect wiring in electricity meters,a ZigBee wireless sensor network-based automated perception and diagnosis system for incorrect wiring in electricity meters is designed.Sensor nodes collect real-time electricity meter data and use empirical mode decomposition to remove noise present in the data.Based on this data,DS evidence theory is used to perceive incorrect wiring of the electricity meter.When an error is detected in the wiring of the electricity meter,the edge server immediately respond and send the perception results and preprocessed electricity meter data to the cloud in a timely manner.After receiving information from the edge,the cloud server uses support vector machines to achieve automated diagnosis of incorrect wiring in the electricity meter.Implementation shows that the system has the ability to accurately perceive and diagnose incorrect wiring of electricity meters,with an AUC value of 0.92 or above.
