A Defence laboratory under
the Defence Research and Development Organisation (DRDO), Ministry
of Defence the Combat Vehicles Research & Development Establishment
(CVRDE), Avadi, has designed and developed an Automated Test System
for testing Gun Control System Electrical/Electronic Assemblies
(ATSEA). The system consists of an industrial Personal Computer,
interface box, signal conditioner and a programmable power supply,
all enclosed in a 19 inch rack and a 5 feet console. It is a general
purpose test system which can be employed during productionisation
of MBT ARJUN, MBT T-72, and MBT T-90, besides a variety of other
applications.
The main features of the the
ATSEA are, it is software controlled and has self-check facility.
It is user friendly and guides the operator during the testing
and even hard copies can be made instantaneously. It is ruggedised
system with excellent man-machine interface and is ideally suitable
for all industrial application. This system saves lot of time,
energy and cost and a large number of units can be tested in a
short time and record of diagnostic history also remains available
for post analysis
The Unit Under Test (UUT)
is connected to the ATSEA through an interface and a programmable
power supply. The signal conditioner unit enables analog, digital
and logic signals to be acquired and processed.
It also houses customized
signal generation cards for testing certain special systems of
the tank. The system has been mainly developed for maintaining
the production schedules by quickly testing electrical / electronic
units on the work bench before fitting these to the tank. During
field trials, Electronic & Mechanical Engineers (EME) personnel
also utilize the system for quick and easy trouble shooting of
the faulty units. The UUT can be evaluated for continuity test
between pins; functionality tests and performance evaluation for
reference values.
