There are many types of electric energy metering devices and the on-site wiring methods are complex.The existing mathematical models of mis-wiring and the degree of intelligence of mis-wiring detection are difficult to meet the requirements of on-site detection.In this paper,a method for detection and modeling of electrical energy metering misconnection is proposed,and a model for identifying misconnection with strong adaptability is established.By introducing two sets of parameter functions and data correlation analysis,the parameter function form is established,so that the miswiring identification model has better adaptability.On this basis,the intelligent management system of the wiring data of the electric energy measuring and testing device is designed,which is based on the field working instruments and remote backstage,an intelligent data management system based on low-delay data interaction,real-time information transmission,layered architecture and cloud-based intelligent technology is designed.The experimental results show that the proposed mathematical model and management system can accurately classify the types of miswiring,and have good detection effectiveness and real-time performance,it provides an important technical means to solve the multiple miswiring detection of electric energy metering device.
