AI Technical Summary

Technical Problem

In existing technologies, data acquisition gateways cannot accurately identify the working mode of user interface units, resulting in communication parameters not being able to be configured automatically, which affects system deployment efficiency and operational stability.

Method used

By alternately sending device identification request frames of the 645 protocol and DLMS protocol to downstream terminals, the main feature field is extracted based on the frame header features of the first valid response frame. Combined with semantic verification and format verification, the confidence level is calculated to determine the terminal type and mode, thereby achieving automatic configuration.

Benefits of technology

This improved the accuracy of downstream terminal identification and the configuration efficiency of the data acquisition gateway, and enhanced the system's anti-interference capability and operational continuity.

Abstract

The application discloses a gateway configuration method, device, equipment and medium. The method alternately sends a 645 protocol reading meter number request frame and a DLMS protocol link establishment request frame to a downstream terminal, determines a target communication protocol based on a frame header feature of a first effective response frame, extracts a corresponding main feature field to generate a candidate identification result, and can distinguish between two operation modes of a direct connection mode and a transfer mode of a user interface unit of an electric energy meter. For a result indicated by the main feature field of the user interface unit, secondary verification is performed by checking a meter number semantic of a response frame data area. For a result indicated by the direct connection mode, secondary verification is performed by checking an electric meter serial number format. Combined with confidence degree calculation and a limited retry mechanism, automatic correction of feature conflicts is realized, and the anti-interference capability is improved. Meanwhile, relying on a preset configuration parameter mapping relationship table, an identification result is directly converted into a gateway communication configuration, and the deployment efficiency and operation continuity of a power data acquisition system are improved.
