Tube (TWT) is a microwave tube used in RADAR. It becomes
enormously hot during its operation. Water or air cooling is
required to extract the heat dessipated .
objective of the TWT Cooling system is to extract the heat
dessipated by the TWT and to transfer it into the ambient
air by circulating water passed through an heat exchanger.
The control unit
scans, monitors, displays the values of various parameters
of the cooling system and accordingly controls the motor,
fan and heater. It also indicates if any parameter crosses
the limits and gives out shut down signal.
Presently the VFD
drives are provided with two push buttons , one to reset the
drive and other to get the status of the drive. The VFD
drive output on RS232C port is connected to a special
printer which prints the
output with date and time stamped. The disadvantage of
existing system is that the drive output will not be
accepted by any other printers and also manual intervention
is required to get the status of the drive.
HMI LCD Panels
are designed to receive signals from VFD drives on RS232C
The received data
is transmitted on to another RS232C port (Console port)
which is routed to a remote PC, where it is stored and
presented in various formats.
data is also routed to the printer ,
stored in internal Flash Memory
and displayed on the 320x240 pixels LCD
after date and time stamping.
User can view a particular page of information
available in the flash through keypad and send it to the
printer on giving a print command.
function done by HMI LCD Panel is to automatically get the
drive status at regular intervals of time by means of
closing a relay contact parallely wired to the existing push
& Distribution Panel for WLR Application:
consists of various electrical switching circuitry,
distributing the load from the main source to other
electrical devices which is used in off-road vehicle mounted
feature of this panel is that it controls two different
types of electrical sources operating at 415V/50hz and
The panel also
has indicating lamps to indicate the status of the
electrical devices. The panel is provided with EM/EMC
gaskets, so that the operation of the switch gears present
inside the panel will not affect the operation of other
devices outside the panel.
The panel is
provided with state of the art indicators to indicate
various electrical parameters.
Acquisition from Legacy System
Systems like material composition analyser, weighing systems
or communication systems designed decades ago had only
interface to a printer for periodic or event driven
printouts. With the latest networking and web based
technologies in place it has become a necessity to get the
data from such legacy systems also and integrate.
Data Care Group
has taken up several such projects to get interfaced with
any kind of printer port, the legacy systems have through a
dedicated hardware and make it compatible to PC comport.
Thus, available data is captured on to the PC through
application software developed in house. The data is also
presented to the user in various formats through front-end
software package. The history of data is also maintained for
future retrieval purposes.
of Magnetic Tapes
Mineral Survey Division of Geological Survey of India (GSI)
had lots of data recorded on to old Magnetic Tapes while
doing Aerial Survey with the help of on board instruments
which were compatible to VAX systems on which lot of
software was also available to analyse this data. For
obvious reasons the VAX systems had to be scrapped which
meant the Data on Magnetic Tape has to be brought on to a
medium compatible to PC [DAT Drive].
Data Care Group
successfully completed the task of transcribing the data
available on magnetic tapes [about 1500 tapes] into DAT
and software was deployed to implement the same.
System for Combat Flight Simulator
The pilots of
combat Aircrafts are trained using Flight simulators. To
create a real environment there is a need to establish voice
link among trainee, instructors, master controller etc.,
Along with the voice other external sounda like Engine sound
etc., have to be mixed to bring out real environment.
The Audio system
has following features.
Six voice channels for intercom.
Audio mixer for Aural
cue wave files generated by a computer.
sound, crackling, hissing
song etc., sounds simulation.
G-Dim effect for the trainees.
Recording output for sound recoding to be replayed in
