Energy Counter
Internet
Energy Counter (in future-IEC) is purposed for measuring of
spent (produced) electric energy, and also other resources
(water, gas), with feature of viewing measurement results
from the Internet.
The view of the IEC is shown on Fig.
As the source of signal, IEC uses pulse output of digital
energy counters. The IEC can be connected to digital energy
counters of the other resources (water, gas), if they have
pulse output.
The IEC connects to Internet through connector RJ45. The IEC
shows information from the website that is stored in the internal
memory of the IEC through HTTP protocol.
Functional block diagram is showed on the Fig.
The
device consists of next blocks:
- embedded web server - WEB PC;
- single-chip Microcontroller;
- Read Time Clock with non-volatile static RAM and Back-Up
battery.
Basic technical characteristics of the IEC are in the Table

The IEC provides viewing from the Internet next measurement
parameters:
- total spent (produced) electric energy in kWattohours (
accurate up to 1 Wattohours);
- active spent (produced) power in Watts;
- total spent (produced) electric energy during last month.
Unit is kWattohours;
- total spent (produced) electric energy during last day.
Unit is kWattohours;
- current time: hours, minutes, data, month and year.
The IEC provides feature of changing next parameters from
the Internet:
- total spent (produced) electric energy;
- current time: hours, minutes, data, month and year.
Parameters are protected from unauthorized changing with password.
All measured parameters are stored into Energy - independent
(non-volatile) memory. After applying the power, the IEC reads
these parameters from NV RAM. In this case the feature of
restoring parameters after power supply fail is provided.
The IEC provides the feature of updating the website and uploading
it to the IEC with utility program - Site Linker.
For accessing the IEC website the Internet Explorer should
be started on users PC. In address row enter: http://141.37.152.101
, where 141.37.152.101 - the IEC IP address.
