An Enhanced Data Acquisition System
FPGA Leads to Cost and Space Reductions

Prosig Ltd is a small, rapidly growing company that designs,
manufactures and markets high quality data acquisition and data processing
systems for harsh environments such as those experienced in the automotive,
power generation and fatigue testing industries. These field data acquisition
and analysis applications include vehicle development and refinement in
the automotive industry, and condition monitoring with emphasis on vibration
in power generation industry. The company employs 45 staff, and in 1998
the company achieved sales of 3.3 M Euro. 30% of the company's sales are
achieved from the Protor data acquisition system.
The company's Protor data acquisition and data processing system utilises
discrete digital and programmable logic device (PLD) technology to implement
the Plant Monitoring Module (PMM) which is central to the functionality
of the system. The generation of speed monitoring and clock generation
functions using this technology limits the equipment's performance in
terms of its range and resolution. The increasing data acquisition rates
required as the speed of many of the plant items now being monitored is
increasing made it essential that the PMM capabilities are upgraded.
The market for vibration condition monitoring is also cost sensitive,
particularly in the UK. Any reduction in hardware costs provides commercial
advantage. The objective of the application experiment was therefore to
introduce cost savings by the rationalisation of the system architecture
and reduced component costs based upon the use of a flexible FPGA technology,
and to improve the systems performance.
The FPGA device enabled the following functional improvements to be made:
i) Replace the speed sensing and clock generation circuit with one that
has sufficient bandwidth to cope with current and future demands for monitoring
of plant with higher shaft frequencies.
ii) Replace clock circuits based on a combination of discrete components
and small scale programmable logic devices with a single in-circuit programmable
device implemented on a PC/104 compatible PC interface card.
iii) Rationalisation of the main PROTOR hardware component through the
use of proprietary hardware made possible by the availability of a standard
PC card with the required clock logic.
The rationalisation of this key component of the PROTOR system provides
not only extended operating parameters but have significant impact on
the manufacturing and maintenance cost of the system. The increased product
sales will result in a return on investment (ROI) of the prototype development
costs of 27 KECU over the product life of 5 years of 500%. The payback
period for the investment costs in developing the prototype system is
The duration of the application experiment was 9 months.
The application experiment will develop a sustained company capability
in FPGA design, which will enable the development of other improved products,
using this technology.
