Curricular Projects
1. Automation in Railway crossing and train tracking system: (8th Semester) Aim was to develop system for auto closure of railway crossing when the train is sufficiently close to the crossing. Here, a GSM device (Global System for Mobile Communications) which is in the train automatically dials other GSM (mobile number) which is at a crossing. System also gives continuously position of train in the control room. GSM device was controlled and operated using 8 bit microcontroller. “AT” commend were used to operate GSM devices. Project aim was to solve real world problem. The project was real time hence challenging. Credit:6 Grade Obtained : AA(10 out of 10) 2. Boosting and maintaining constant dc voltage output in RLE load: (7th Semester) The aim was to Boost 16 volt to 48 volt and to maintain 48 volt constant voltage output across the RLE load. Using PI controller, feedback was taken and triggering of switch was done. It was desired to achieve 2 characteristics. Firstly, for a momentary change or disturbance in source, output must remain constant and secondly, after first overshoot system voltage should never go below 40 volt. This was achieved by a compromise with a ripple of +-1 volt at output. Model was simulated using MATLAB. Credit:2 Grade Obtained : BB(8 out of 10) 3. Railway signal control at mega station using micro-controller: (6th Semester) Aim of the project was the regulation of traffic signals in a multi–track railway system at a megastation. Assuming position input of the train, program was written in such a way that there was automatic signal control. So, for each input state condition, there is only one desired output which is achieved by Microcontroller(Philips 8 bit). Credit:1 Grade Obtained : AA(10 out of 10) 4. Railway line signal control using flip flop: (5th Semester) Auto-regulation of train traffic lights controlled by sensors detecting the movement of trains. Aim was to concentrate on efficient use of each state of D-flip flop to reduce the complexity of the system. Credit:1 Grade Obtained : AA(10 out of 10) 1. Admittance Measurement of Piezoelectric transducer: The goal was to combine fast measurement with high frequency resolution near resonance and anti resonance area of Piezoelectric transducer. The essence of the Program is that it detects resonance area itself and adapts small steps for more measurement points in this area. The subsequent step depends on the preceding two steps. Adaption of the steps is done by making arc tangent graph trajectory as the reference. In other regions measurement time is reduced using larger steps .Program was written in Agilent VEE Pro. User can set any frequency range and resolution according to his convenience depending on how smooth and accurate result he wants.

Build a System that is capable of finding object in its Surrounding: The goal was achieved using d-SPACE control desk, MATLAB/Simulink, Stepper motor and Infrared sensor. Two types of object detection algorithm were developed. The purpose of the system was to identify all the objects in its surrounding and after scanning, it would end up with the centre of the object according to algorithm.

To Upload calculated arbitrary waveform into wave form generator using Vee Pro Graphical Programming: In our day to day life we have arbitrary data containing thousands of points in a file like notepad. The aim of the task was to write a user Friendly Program which extracts points from the file and sends it to the waveform generator. The output of waveform generator can be sent to the oscilloscope where the user can observe it physically.
