A low-voltage distribution station area contains many different types of operation monitoring and metering equipment, and some parts of their function and hardware composition are duplicated, which leads to issues such as the waste of device resources, high operation and maintenance costs, etc. By integrating the hardware and software packages of four conventional operation monitoring and metering equipment in the low-voltage distribution station area, optimization of different measurement equipment and a modular intelligent fusion terminal for the low-voltage distribution station area are proposed. The terminal remains all functions of the original operation monitoring and metering equipment in the low-voltage distribution station area, and beyond that, a variety of modularized interfaces and applications can be configured to increase the terminal flexibility and extension at different low-voltage distribution station areas. If the charging and using facilities in public places are also included in the scope of supervision, the functions of this modular intelligent fusion terminal will be further expanded, which can provide corresponding technical support for the construction of the energy Internet.
