The system allows for integration with various information systems through different mechanisms:Sharing files in the required format (support the current format or develop a new).

The automated system is created as the information-computing system with centralized control and distributed measurement function.

In this proposal automation objects are:introductory switchgear device;the metering of heat and water;Central collection and processing of information .The automated system includes a system ensuring universal time, which is implemented at all levels of the hierarchy. System universal time is normalized metrological characteristics and must ensure time synchronization in an automated system with accuracy not worse than 5,0 sec/day. For ensuring the uniformity of measurements uses a single calendar time.

As communication channels can be used:GSM/GPRS;TCP/IP;Dial-up modem channel;Priority is the use of GSM channels because the coverage and the tariff policy of mobile operators allows you to connect facilities across the country quickly with a minimum of installation and configuration. The main mode of the channel must be GPRS, for implementing a parallel poll of devices to provide the desired rate of data delivery.In the absence of information transmission on the priority channels of communication automatically switches to another channel without losing the quality and quantity of data.

Functional subsystem for monitoring and control provides:analysis of event logs of devices;analysis of the output setpoint for the physical and contractual parameters of energy consumption;monitoring availability of communication channels;monitoring the status and operation of the AMR system;hardware diagnostics AIIS KUE;visual display of the results of monitoring and diagnostics;remote from the level of the CPI, the hardware configuration of the AMR system;remote on/off energooborudovanija.The results of the monitoring subsystem should display on the workstation of the administrator and the operators in the form of mnemosina, tables and graphs to quickly assess system status and to search for elements warning /alarm/ fault. In the case of the special importance of events must be a way to alert users by SMS and email.

Changes in automated accounting system of electricity during their operation, requiring renewal of the certificate of type approval and changes in the type description:- Increasing the number of measuring channels included in the previously approved type of automated accounting system of electricity, provided that the added measurement channel will not affect the automated metering system previously approved type;

In case of positive results of tests for the purpose of type approval added part of the automated electricity metering system issued a new approval certificate type.In the name of the system added the words "amendment No. 1".Old certificate (certificate) type approval for the Rosstandart when you receive a new certificate.

To a new certificate of type approval accompanied by the following mandatory attachments:1. The original description of the type of the automated electricity metering system before the Change;2. Description type added on and you added earlier (if not first) part of the automated electricity metering system

A review of the effect of adding a measuring channel of an automated metering system previously approved type is needed if from the analysis of the scheme and design of the basic and added parts to make an unambiguous conclusion about the absence of the above effects.If conditions are not met, the system again appears to be entirely on tests for type approval.

In accordance with GOST R 8.563-2009 in the method of measurement can be changed. The changes the developer makes. The measurement procedures as amended by the changes submitted for certification, conducted in accordance with this standard.

At replacement of measuring instruments in the measuring channel (transformer current, voltage transformer, meter) to measure identical type with preservation of the metrological and technical characteristics, this change is based on the act of replacement means of measurements recorded in the table of measurements and approved by the technical supervisor of the owner of the automated electricity metering system.
