ENKM-2 - USPD for data collection from all-house and residential meters

General information
From household and all-house electric power meters CJSC Engineering Center Energoservice has developed for data collection and makes collecting devices and data transmission of the ENKM-2 series.
Group USPD and all-house USPD enter the ENKM-2 series.
Provides to all-house USPD data collection from counters as directly via the available interfaces, and by means of group USPD, and also allows to organize communication channels with the center of data collection.
Data exchange between group and all-house USPD happens on a radio channel in the frequency range of 433 MHz or on a power network on the basis of the PLC technology.
Data exchange between all-house USPD and the center of data collection is carried out on GSM channels (CSD or GPRS) or the Ethernet networks.

Group USPD
are issued in the following executions:
 USPD ENKM-2-AR: the data transmission environment - a radio channel 433 MHz
 USPD ENKM-2-AR: the data transmission environment - a power network (PLC)

Group USPD represents the communication device with functions of data collection. Group USPD provides data collection from counters (automatic reading of meter readings on rates for the determined day of month according to the schedule or providing the transparent channel of access directly to counters) with support of the following communication channels: radio channel, PLC. The main objective of group USPD - to provide data transmission from the distributed objects on all-house USPD.
Association of group USPD in a uniform network of data collection among themselves and all-house USPD is carried out: in wooden houses on a radio channel 433 MHz and PLC, in panel, brick and monolithic houses mainly on PLC.

All-house USPD
are issued in the following executions:
 USPD ENKM-2-GAEPR: 1 RS485 port, support of PLC with three-phase connection to a power network, a radio channel 433mgts; built-in GSM modem (CSD or GPRS), 1 Ethernet port; synchronization of the built-in watch from the center of data collection.
 USPD ENKM-2-GAEPRT: too, plus the built-in receiver of navigation satellites for synchronization of an inner clock.

All-house USPD represents the head communication device with functions of data collection. USPD provides the transparent channel of access directly to counters and automatic data collection from 255 metering devices (the indication on 4 tariff zones) according to the schedule or: on the RS485 interface directly from counters; from group USPD using PLC with three-phase connection to a power network; from group USPD on a radio channel 433mgts.

Providing a communication channel between the center of collecting and all-house USPD requires performance of the following conditions: the server of data collection should have access to the network the Internet with the static IP address (it is appointed Internet service provider); in a setting point of USPD there is an access to the GSM network with the normal level of a signal.
