Data Acquisition System
This application is used for the specific
scientific applications like
Thunder Capturing System
Atmospheric
Electricity Monitoring System.
The Special device having 12 bit ADC is
attached to the computer, which senses the charge and sends
data to the serial port of the computer. This data is in the
form of interrupt, which is served by the program and is termed
as Online Data. This data can be HEX, ASCII or Binary depending
on the chip used in the device. This online data is processed
in three ways
On Line Numerical Display
On
Line Graphical Display
On
Line Storing Of Data
The speed of this data, and channels to
be monitored depends upon user's choice. Thus the program
can orient the external device as per requirement. This part
is termed as System Control. This system control orients the
device in the following manner
Vary
the number of channels
Vary
the speed of sending on line data
Change
the groups, having similar parameter for the scientific process.
Further the stored data can be combined
in a one file, for viewing at later time by the scientists.
This data is termed as History. The operations possible on
the history data are:
Making
a single file of the specified period.
Make
an ASCII format file,for viewed offline, without starting
application.
View
the graph of the history
View
the tabular view of the history
Running
the graphical view according to the user speed.
Fast
forward, or slow motion facility
A special ActiveX component is developed
for displaying the data in the graphical view.
The X - axis of the component displays
relative time in HH: MM: SS format and the Y - axis of the
component displays the values of the captured data. The component
has another facility of running the history data as per user
required speed. Thus the time and the values which are shown
in the graph are related with the speed setting that user
has selected.
