Abstract:
Solid State Auto-Loader is a robust control systems in main battle tanks to enhance the
firepower and maneuverability. The auto-loading mechanism consists of two subsections, the
‘Motorized Mechanical Subsystem’ driven by several high power motors and solenoids along with
the mechanical proximity switches. The other part is the ‘Electrical Control Subsystem’
responsible for coordinated control of various operations carried out by mechanical subsystems.
All these are controlled through Solid State Auto-Loader. The Solid State Auto-Loader (SSAL) is
a Solid State system because that has eliminated the need of any mechanical relay and utilizes the
latest Solid State Electronic Devices to provide all the control functionalities hence leading to more
reliable system. The SSAL consists of three Units and all these units are interlinked with each
other using CAN communication protocol. The SSAL consists of three units, ‘Power Distribution
Unit’, ‘Memory Unit’ and ‘Ammo Unit’. All these units uses various Electronic Circuit Boards,
which are used to carry out all the operations of Auto-Loading. During the production of SSAL,
these boards were needed to be tested for the proper functionality and performance. So a system
is needed that can test these Electronic Circuit Boards to reduce the fault errors and ensure its
proper functionality in least amount of time. This research presents the development of Smart
Testing Jigs for testing of all the Electronic Circuit Cards used in SSAL of T-85 UG, Al-Khalid
and Al-Khalid 1 Tanks for proper functionality of all its Electrical Controlled Outputs as well as
Inputs from various sensors and switches. Testing is done autonomously without the intervention
of a person and pin-points particular Input or Output Signal(s) that are malfunctioning.
