Measuring and Information Systems (MIS) are portable measuring devices intended for continuous monitoring and archiving parameters consumption (production) of electricity that is taken via a number of energy branches.
Depending on the choice of locations where the parameters of electric power consumpiton are necessary to monitor, and number of branches, there are several variants of MIS developed: MIS 2, MIS-4S, MIS 8, MIS-1mV.
The architecture of MIS is based on two main components: measuring part and information part. The measuring part consists of panel network analyzers, and information-relevant embeded computers. The aforementioned interoperability of the INTELLEMS system elements can already be seen at this level because the panel network analyzers of various manufacturers can be used for the realization of the measuring part (Circutor, Socomec, Schneider, Lovato, etc.).
The main purpose of the MIS is to periodically read the measurement information from the panel network analyzers to store them on the computer’s memory unit (hard disk, solid state disk, SD card, MML card, USB flash memory stick, etc.).
In the first MIS variants, data acquisition was being done manually via a USB memory stick, thanks to intelligent agents developed for these purpose.
Later, the user requirements were such that they require an upgrade of the system in terms of adding a modem communications, automatic data transfer to the appropriate remote centers. In this sense, the number of available communication modems has been tested so far (dial-up, ISDN, ADSL, Wi-Fi, GSM / GPRS, 3G, digital radio modems and their combinations) and a large number of MIS is connected to remote centers. Depending on the user’s desire, communication is accomplished using various modems, and often multicommunication systems that provide redundancy in the event of a communication channel failing are used.
For this purpose intelligent agents have been developed that in the case of an outage of the communication channel automatically continue the transfer of data through another channel without interrupting the transmission that has already began.
The establishment of communication and mass transfer of data between MIS and remote centers has enabled this product programme to be upgraded by the development of intelligent agents, by adding control functions, local and remote control, and by integrating individual components into a comprehensive multi-agent system.
