Data collection (Downloading): The PQSCADA server system is re-
sponsible for collecting all continuous data (PQZip files) from a con-
nected device automatically. When the device is connected (wired or
wirelessly) the PQSCADA server automatically checks for any new
data availability using an FTP
6
communication protocol.
Placing new files into the Incoming data folder: All new PQZip files
found on a connected device are copied (the original files remain on
device) to a temporary location on a local hard drive “Incoming data
folder”.
Data processing and storage: The next stage is data processing, in
which the data is being organized for storage and quick access (Stage
1) and then a variety of electrical parameters are being calculated
(Stage 2) based on the raw PQZip data. The reorganized PQZip data, as
well as the calculated parameter statistics are being stored in a local
SQL database. The files which have been processed and successfully
inserted to the database are then removed from the Incoming folder
Networking: The PQSCADA server integrates a dedicated HTTP (de-
fault port 80) interface that communicates with the PQSCADA Man-
agement Studio (interactive management application) and the Elspec
Power Quality Investigator (data analysis application) running on either
the same or different machine.
PQSCADA Management Studio
The PQSCADA Management Studio is an interactive tool which provides full
control and monitoring of all of PQSCADA’s activities.
