Design and Development of ARJUN MBT Tank Engine Control Junction Box using Micro Controller

This paper explains how we can replace the conventional power-consuming mechanical relay based Engine Control Junction Box of ARJUN MBT Tank using Micro Controller. The aim of this paper is to minimize the size of existing ECJB and to reduce the complexity of operation. The existing ECJB has 4 normal relays, 16 special type relays and 4 critical relays for smooth operation of the engine and is hardwired, thus making it difficult to operate and troubleshoot. By using 8051 microcontroller we can overcome the existing problems of ECJB. It implements the following parameters and operation. • Starting Sequence • Starter Interlock • Sequential switching of Dust Eject motors • Display the sensor information to the driver • Automatic shutdown The advantage is that it possesses inbuilt fault diagnostic function. The size has been reduced to 1/4th of the existing ECJB, only indigenized components and relays are used and imported items are totally eliminated.
