3 Data Format
The data stored on the files of the DA15K control unit are formatted according to a standard SIAP + MICROS
record structure, defined as
Dynamic record track
.
The Dynamic record track contains all the information about the station (station number), date and time of data
stored and the type of stored data.
In the record tracks of type
dynamic structure
, the length of the track is VARIABLE
depending on the number
of measures and data type. Therefore, in situations where the data to be inserted in the structure are minimal,
the length of the structure itself and
– consequently - also the space occupied by the data become very low.
This track is suitable to contain the instantaneous data (provided continuously by the control unit), the statistical
data (made available by the control unit with the preprogrammed scan), and the alarm data and calibration
data (made available by the control unit which could be turned on depending of the event).
The record is composed of three parts, named:
HEAD
BODY
TAIL
Each of these parts of the track is internally divided into comma separated fields "," character (ASCII 44). All
the data (Instantaneous Data, Statistical data, Alarm Data, Calibration Data, etc.) managed by the system are
stored in the internal memory (RAM) of the control unit and, if present, in the external memory (memory card).
Depending on the data type, storage is carried out in distinct areas of the memories. The division into areas is
dictated, as described below, by specific storage needs.
Data
are stored in the memory area corresponding to them. They are stored as a sequence of ASCII
characters. The data storage mode depends on the specific type of concerning
data
. These modes are
described by
Record tracks
which define the structure. Four different storage modes have been implemented,
one for each type of
data
.
In detail the four types are:
•
Record track for Statistical Data
•
Record track for Instantaneous data
•
Record track for Alarm Data
•
Record track for Calibration Data
