Abstract

The invention relates to an intelligent protocol conversion device used for solving the problem that different metering instruments have different communication protocols, and unified remote information collection cannot be performed and provides a communication interface conversion device from an RS-485 interface or an M-Bus interface to a PLC interface or a micropower wireless interface and a method of controlling the device. The intelligent protocol conversion device comprises a control circuit 21, a memory cell 23, a clock circuit 22, an M-Bus interface circuit 24, an RS-485 interface circuit 25, a PLC module 27, a micropower wireless module 27, a power supply and a battery circuit 26 and the like. The intelligent protocol conversion device can recognize standard data frame structuressuch as DL / T 645-1997, DL / T 645-2007, DL / T 698, CJ-T 188-2004, MODB US and IEC 62056 and converts the standard data frame structures to other one of the standard data frame structures according to a given set or an automatic learning result.

Description

technical field [0001] The invention belongs to the field of instrument communication, and in particular relates to an intelligent protocol conversion device for meter communication. Background technique [0002] Metering instruments are widely used in our daily production and life, mainly including electric energy meters, water meters, gas meters, heat (cold) meters, etc. Among them, electric energy meters are used to measure electric energy, and the application volume in my country has reached 400 to 500 million. The current communication protocol is mainly the DL / T 645-2007 standard and its filing documents for the electric power industry, and some are DL / T 645 for the electric power industry -1997 standard, it is expected to turn to the DL / T 698 standard in the power industry in the future; water meters are used to measure water consumption, and the application volume exceeds 400 million, most of which are speed water meters, not electronic meters yet, and are completed b...
