PROMOTIC METERING

System architecture

The system architecture is built on client-server platform
A) The communication, data and Web server (with visualization) provides:

B) Visualization Web clients allow inspectional visualization of all data gathered from meters and provide output reports and summary overviews of energy consumption in defined time-range.

Communication with energy meters

The communication with meters usually uses M-BUS or M-BUS Ethernet protocol. Meter addresses can be entered either as direct (meter address on M-BUS link) or as so-called a secondary address (usually represented by the meter serial number). The latter approach is handy especially if a failed meter is replaced by another. The reading period (frequency, time) can be defined in the configuration file.

Examples of data gathered from meters: Reading period (time) can be entered globally for all groups or independently for each group. The reading time can be entered as:

Visualization

The status of all meters is indicated on the overview visualization screen and it is also possible to display detailed information of each selected meter.

System configuration

The number of meters connected to the system is not limited (249 meters can be defined in one group, number of groups is not limited). Authorized personnel can add meters into the sytem and edit parameters (meter type, name of measured locality, device address etc.). After the application is launched all the parameters are read from configuration files, then the system automatically establishes connection with defined meters and reading the data. The system also provides initial identification of meters that are connected in each group (so-called initialization mode). Meter parameters that are read are then saved into initialization files. Additional parameters can be then added by system administrator:

Archiving and evaluation of measured data

The system archives measured data into standard database format (e.g. Access, dBase, MS SQL - as needed). The system also provides evaluation of consumption of energy in defined time-range (day, month, year, user defined range). Consumption evaluation is done for each meter individually or for groups of meters as group summary:



Assignment of meters to summary group is defined in configuration file that is loaded by the application after the application is launched.

Data exports

The system can also provide data exports into files MS Excel that can be used as source data for invoicing. Individual daily consumption data is saved into the file. The format of exported data can be adapted as needed.

PROMOTIC SCADA system

The application for meter data reading has been created in the PROMOTIC system. This software tool can be used to design both simple and complex monitoring systems that can be interconnected with enterprise IS, databases, the Internet, etc. In the PROMOTIC system there are bult-in standard software interfaces for data exchange between technological processes and other devices or systems:



The software can be used in a wide variety of technologies. It provides real time overviews indicating status of all connected meters, executes evaluation and archiving of energy consumption in defined time-range. It is a multi-purpose and highly configurable system that allows to read data from various meters. It can be extended by adding meters without the need to modify the application source code. The user can also export measured data into MS Excel files. The system can also be extended in order to read consumption of additional media: electricity, gas, etc. The system is open for interconnection with other systems e.g. the enterprise IS where the data can be transmitted.
