Abstract:
For fail-safe operation of any plant, machine, or scientific experiment,
the real-time monitoring of every component is essentially critical. Lossless
acquisition of raw data, signal processing, and data storage are the
main electronic processes for the monitoring of machine. The recording
and storage of fast events demand high speed embedded system with
higher storage capacity and speed. The field programmable gate array
(FPGA) is a reconfigurable processor available to work at high speed
~500 MHz with signal processing and computer interfacing features.
The double data rate (DDR) memory is available with 1 G bits capacity
and speed of ~500 Mbps. In this paper, we report the development of
FPGA-based event recording system for monitoring of glass window
fabricated for one of the vacuum chambers. The glass window may
get damaged with time due to high power laser and surroundings. The
FPGA and DDR memory based embedded systems perform routine
checks on the glass window and provide the mechanism for on-board
data storage and send status in real time to other sub-systems during
false events for operating the machine interlock. Details of hardware
architecture, software development, and results are presented in the
paper. We believe that the developed work will be useful implications
in many industrial and research applications.
