At present, the domestic existing distribution and utilization system has various equipment types, such as: a DTU (Distribution Terminal Unit), an FTU (Feeder Terminal Unit), a TTU (Transformer Terminal Unit), and a collector and a concentrator in a power grid in a power Distribution network. Meanwhile, the data protocols adopted by various terminals and devices are also various, such as: IEC60870-5-101, IEC60870-5-104, Q/GDW1376, DL/T645, DL/T698, etc.
The various terminals and the devices transmit the collected data back to the respective cloud master stations, a single cloud master station can only complete the collection and management of a certain type of devices, and the data of various types of devices are mutually separated at the cloud.

Because the existing terminal and equipment mostly load software in a firmware mode, the terminal and equipment have the defects of single function, poor expansibility and inflexible function addition. The unicity of the terminal and the equipment function causes that a plurality of kinds of equipment are required to be installed at the same place to meet a plurality of service functions, and a new network link is opened up, so that the repeated construction of a communication network is caused, and unnecessary resource waste is generated.
The existing terminal and equipment have limited external interfaces, the interfaces are fixed, the flexibility of the interfaces is poor, and new down-hanging equipment cannot be added even if the original equipment still has expansion allowance due to unmatched interfaces. And interface conversion can be carried out, an interface matching device also needs to be added, and the additional space is occupied, so that inconvenience is brought to maintenance work.
The cloud master station platforms of the existing terminals and equipment are numerous, and the cloud data storage is dispersed. Meanwhile, when a large number of terminals and devices transmit data, the dependence on the network is strong, and a large pressure is also caused on the communication network. When the control instruction is issued, the instruction reaches the terminal and the equipment after being transmitted by the cloud master station through the layer-by-layer network, and the control instruction is poor in real-time performance.
