Automated control systems. Introduction. • • • For the decade electric power meters were Automated control systems. Introduction. • • • For the decade electric power meters were constantly developing - from simple and reliable induction instruments to complicated digital devices capable to read, store and transmit through communication channels different settings required for electric power consumption. Accounting systems also had some development stages, each one reflected certain stage of microelectronics achievements and from one-processor systems, which calculates pulses from induction meters verification output, to multi-processor network systems with data exchange through power wires by means of noise-resistant wideband signals. Next five slides show structure flowcharts of most typical accounting systems "INCOTEX" LTD

System destination. • • • Collection, processing, storage and displaying of data on the System destination. • • • Collection, processing, storage and displaying of data on the consumption of the energy from meters. Data grouping according to object initial basis. Calculation of energy granting-consumption imbalance. Consumer load control by remote disconnection (restriction) – connection of power supply. Universal time synchronizing in all accounting system devices; Control log organization and keeping of accounting system equipment diagnostics, emergency events and system operation protocol; Support of local and global networks of the enterprise based on TCP / IP protocol. Ensuring protection from unauthorized access with no possibility of viewing, changing or erasing data by person with no respective rights. Preparing report forms for data documentation of energy carriers consumption. Integration into billing systems. "INCOTEX" LTD

Technology. • Distributing power network 220 V/380 V as data transmission environment is characterized Technology. • Distributing power network 220 V/380 V as data transmission environment is characterized by the following basic parameters: • • • High level of noises and quick high-frequency signal fading Characteristic impedance module in bandwidth from fractions to units and tens of Ohms. Noises of the unpredictable form and power both wideband with concentrated spectrum. Signal unevenness of the frequency characteristic with sharp collapses and peaks. Unpredictable impedance changing in time and along transmission. • In the base data exchange in the system lies data transmission principle with all known signal division types application - temporal, frequency and code, which ensures data transmission in most unfriendly environment. • For high noise-immunity and high data protection level, OFDM-modulation (Orthogonal Frequency Division Modulation) algorithms are used. OFDM-modulation forms resulting signal by multiplexing of several wideband signals. "INCOTEX" LTD

Features. • • Peak radiation power of transmitter - 0, 5 W Modem consumption Features. • • Peak radiation power of transmitter - 0, 5 W Modem consumption current - 7 m. A Number of meters supported by concentrator - more 3. 000 Noise-immunity of the system exceeds in several times noise-immunity of analogues (in amplitude). Modern wideband digital technologies are used for data transmission. Modem module construction allows to build it into different types of meters. System tuning does not require high qualifications and are reduced to installation of individual addresses of meters within network, supported by current concentrator. In case of multi-tariff accounting, meters built-in clock are synchronized from periodically adjusted clock in concentrator. "INCOTEX" LTD

Warranty. • • • Warranty applies to all ‘INCOTEX” products and it is specified Warranty. • • • Warranty applies to all ‘INCOTEX” products and it is specified in passport. Warranty period for meters is 6 years. System servicing is realized within the framework of the agreement between consumer and mounting company. Base software for operation with accounting system is delivered and accompanied free of charge. Software created under technical requirement of the customer is developed and supported on the commercial basis. "INCOTEX" LTD
