Automatic Energy Metering System-building Steps

Automatic Energy Metering System-building Steps:

Device Required:

i) Energy meters with communication facility in my case RS485

ii) Remote serial server (Wired/Wireless) connected to energymeters 

iii) Client server

iv) Existing Local area network

STEPS:

First connect energy meters to the remote serial server through data communication cable in daisy chain method maximum upto 30 nos. Then connect the remote server to the access point if you want to transmit data wireless or directly to RJ connector for wired LAN.

Now write a software for client server communication using any language you know like Java, Visual Basic, Pearl, C etc. Using Modbus protocol.Make sure that query should matches with energy meter vendor memory map.

Next step is to build a database in station server or dedicated Machine to store energy meter data for future use. 

For this purpose you can use open source databases like MySQL, PostgreSQL.

Once you are able to communicate with remote meters successfully, afterwards you can manipulate data for representation. Later you can implement security for commercial application.

Any further queries don’t hesitate to communicate...
