Intelligent distribution transformer terminal and intelligent electric meter interaction method based on HPLC communication channel

Abstract

The invention discloses an intelligent distribution transformer terminal and intelligent electric meter interaction method based on an HPLC communication channel. The intelligent distribution transformer terminal state monitoring system comprises a high-speed carrier communication module, a concentrator, an HPLC communication channel, an APP of an intelligent distribution transformer terminal, a power line and an electric meter. According to the distribution transformer terminal state monitoring system superior to a traditional distribution transformer terminal and an existing distribution transformer terminal system, the intelligent distribution transformer terminal performs data interaction with CCO in a concentrator through an HPLC communication channel. According to the scheme, protocols of a physical layer, a data link layer and an application layer of a high-speed carrier communication technology in the power utilization information acquisition system do not need to be modified,upgrading operation on the concentrator is not needed, and acquisition service of the power utilization information acquisition system is not affected.

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
