Abstract

The invention discloses an interaction method between an intelligent distribution transformer terminal and an intelligent electric meter based on an HPLC communication channel. This intelligent distribution transformer terminal status monitoring system includes a high-speed carrier communication module, a concentrator, an HPLC communication channel, an APP of the intelligent distribution transformer terminal, a power line and an electric meter. A distribution transformer terminal status monitoring system that is superior to traditional distribution transformer terminals and existing distribution transformer terminal systems. The intelligent distribution transformer terminal of this scheme performs data interaction with the CCO in the concentrator through the HPLC communication channel. This solution does not need to modify the physical layer, data link layer and application layer protocol of the high-speed carrier communication technology in the power consumption information collection system, does not need to upgrade the concentrator, and does not affect the power consumption information collection system.

Problems solved by technology

However, due to the technical specifications of the concentrator for the electricity consumption information collection system, the RS485 interface of the concentrator is mainly used for data collection of the general table of the station area, and the communication protocol uses the DL / T645 protocol. Therefore, the concentrator software needs to be upgraded to match The use of intelligent distribution transformer terminals involves the software development and upgrade of concentrators, and the time period is long, and when intelligent distribution transformer terminals are applied in a large area, due to the large number of concentrators and the large number of manufacturers, it is difficult to apply them in batches

[0007] Moreover, the intelligent distribution transformer terminal occupies one RS485 interface of the concentrator, and the number of electric meters connected to the concentrator through RS485 will be reduced.

[0008] In addition, RS485 lines need to be laid when installing intelligent distribution transformer terminals, resulting in time-consuming construction and increased costs
