A method and device for framing DL/T645 protocol messages based on XML

Abstract

This application provides an XML-based DL / T645 protocol message framing method and device. The method includes: after receiving the message sent by the remote end, reading the XML document of the message, and determining the structural information of the message according to the XML document of the message; then according to the structural information of the message, Analyzing the frame field node in the frame message node to obtain the attribute value of the frame field node; then creating a character array, and assigning a value to the character array according to the attribute value of the frame field node to form a target message, Then send the target packet to the destination address. In this way, no matter whether the DL / T645 protocol message is customized by the manufacturer or not, the DL / T645 protocol message can be framed, so as to achieve a unified description of the structure of the DL / T645 protocol message and avoid DL / T645 protocol message structure. There is a deviation in the understanding of part of the content of the T645 statute.

Description

Technical field [0001] The present application relates to the field of data processing, and Background technique [0002] Power industry standard DL / T645 multi-function power meter communication statute is a communication protocol when data exchange with data acquisition terminal devices, and can make energy meter manufacturers and electricity information collection terminal manufacturers with unity. The standard is interactive, thereby avoiding the repeated investment of the equipment, simplifying the workflow of the electricity information collection, speeding up the marketing modernization and metrology standard standardization construction. [0003] After the issuance of the DL / T645 power meter communication status, most of the energy gauges contains the DL / T645 specification, but there is a partial power table only contains custom protices for manufacturers, and it is easy to understand some of the contents of the DL / T645 protocol. Therefore, it is necessary to unify...

AI Technical Summary

Problems solved by technology

[0003] After the promulgation of the DL / T645 electric energy meter communication protocol, most electric energy meters contain the DL / T645 protocol, but some electric energy meters only contain the custom protocol of the manufacturer, and it is easy to understand some of the content of the DL / T645 protocol.
