THE DOMESTIC HOUSEHOLD ELECTRIC POWER METERS WIRELESS SCANNING SYSTEM
The development of this system was dictated by the need to solve existing and emerging issues under the today power market conditions:
• prevention of unauthorized electric power consumption by the domestic household;
• control of domestic networks for the discovery of unauthorized power consumption;
• monitoring of electric power consumption and timely payment by residential electrical customers;
• adjusting of electric power consumption by means of debtors’ service disconnect;
• electric power supply-and-demand balance analysis by districts, substations, houses;
• energy management in the electric power owner’s networks;
• cost reduction and “simplification” of the commercial power consumption data collection, storing and communication systems configurations.
Electric power meters wireless scanning system developed by the «NIK» company solves all set challenges by means of the following possibilities implementation:
• non-contact power accounting data collection from the electric power meters;
• data collection capability without accuracy loss regardless of the number of house storeys and number of customers;
• remote monitoring of electric power balance;
• availability of the non-volatile memory in the used instruments for registration of all unauthorized interventions to the data collection system;
• remote control of subscribers’ service connection/disconnection;
• unlimited scanning network expandability.
The proposed data collection system is designed for the use of electric power meters of the NІK 2303 and NІK 2104 type allowing the data transfer by means of built-in radio modem with the internal antenna and output amplifier improving the radio signal transmission.
Availability of radio modem enable meters to compose a self-organizing and self-restoring net.
The data collection controller functions as the main collecting, data-base forming and data storing device. The data collection controller KC-01 is stand-alone functional device, which automatically arranges and controls up to 1000 electric power meters. Any meters connected to or disconnected from network are instantly recognized by the data collection controller scanning the devices within the limits of reach, and thus a network is under constant check and is adjusted at specified intervals. The controller provided with radio channel by means of radio-module IEEE802.15.4 (2.4 GHz) with the internal or external antenna functioning as main data communication channel with the electric power meters.
The controller collects data both directly from the electric power meters and from the switching controllers, which could be installed in the system as intermediates between meters and collection data controller in adverse propagation locations. Power consumption data are communicated to the upper level of the system by means of data-base replication with the use of the connected communication channels (for example, the Internet as a main channel and GPRS as a redundant channel). The controller КС-01 could be used both as data collection and storage server and as router for the remote access to the electric power meters.
At the upper level of the system the NovaSyS - Energosbyt program complex functions allowing system administration, generation of various configuration reporting forms, communication of preformatted primary and computation data to the billing system of energy-supplying organization or to other parties in interest.
Data controller КС-01 - is the main link. When being used in AMR the controller receives data both from the electric power meters and from the switching controllers, which could be installed in the system as intermediates between meters and data collection controller Electricity supplier has access to the KC-01 through RS-485 and RS-232 interfaces. Also, the device has an additional interface for configuring and programming the controller from the computer.
NІK 2303 Electric energy meters for measuring of active and reactive energy, gross output, cos φ, voltage and current intensity root-mean-square values, and for arrangement of multi-rate power accounting in the three-phase three-wire and four-wire alternating current circuits with the transformer and direct voltage connection. Meters are available with following interfaces installed: radio channel interface, electric interface “current loop” 20 mA, RS-232 or RS-485 for the remote data communication.
NІK 2104, NІK 2104Т Electric energy meters for measuring of active energy, instantaneous power, voltage and current intensity values, and for arrangement of multi-rate power accounting in the single-phase alternating current circuits of domestic purpose and in other industries.All meters have pulse output, optical port and four-wire electric interface RS-485 or radio channel for the remote data communication depending on version.
Extender R-485 is portable device in individual water-proof casing intended for the data communication between the device with the interface RS-485 and other devices equipped with the radio channel IEEE 802.15.4 (2.4 GHz). The interface RS-485 communication rate could range within the limits of 300 – 9600 baud. 
Access point is portable device to be connected to the computer through USB port enabling the radio channel IEEE802.15.4 (2.4 GHz) communication with other devices equipped with similar radio channel, in particular, with the meters of the NIK type.
