摘要: 智能电表大多采用MODBUS协议或者645协议进行通信,通信速率不高,这对于智能电表大量数据的传输不方便。提出基于PROFIBUS的智能电表数据抄读方法及系统,此系统包括基于PROFIBUS通信的主站——可编程逻辑控制器(PLC)和从站,主站和从站是基于PROFIBUS总线通信连接的,主站由西门子PLC/CP5611网卡和STEP 7编程软件、WINCC监控软件等组成,从站为具有PROFIBUS模块的智能电表;该PROFIBUS模块与智能电表中的微控制单元(MCU)进行连接,作为智能电表的一部分。这种基于PROFIBUS的智能电表数据抄读方法及系统易于实施,数据传输快,且通信速率可以达到12Mb/s。

Abstract: Communication of most smart meters is based on MODBUS protocol or 645 protocol, which is insufficient for the transmission of large amounts of data from smart meter. A new reading method and its system based on PROFIBUS were proposed. The system included PROFIBUS based master (Programmable Logic Controller, PLC) and slave stations connected by ROFIBUS bus, and the master station consisted of the Network Interface Card (NIC) of Siemens PLC/CP5611, STEP 7 programming software and WINCC monitoring software; the slave station was a smart meter which contained a PROFIBUS module wired with the Micro Control Unit (MCU) in the smart meter. This PROFIBUS-based reading method and its system of smart meter's data is easy to implement, fast in data transmission, and with communication rate of up to 12Mb/s.

Key words: smart meters, PROFIBUS, communication rate, reading method
