Item Automated Parking System(2018-10-24T12:34:59Z) Sanjay, S; Samarth, Sharma; Priyanka, Pramod Wani; Akshaya, C RThis report talks about one in many alternative contrivances of parking a vehicle in any mall or parking alley other than the ancestral method which requires the person to park the car by himself and thus by consuming his time, this paper eliminates the need of doing so by allowing the car to be parked automatically in the empty slot and retrieving it automatically without any time or effort of an person. The vehicle to be parked is driven onto a robot by the concerned person and each vehicle has a unique RFID tag. The vehicle and its entry time is recognized by RFID reader placed at the entrance and stored in the database which will be crucial in retrieving the vehicle and cost estimation for the parked duration. Once the vehicle to be parked is placed on the robot and is identified by the RFID reader, a microcontroller containing the slot details of the parking slots with the help of infrared sensors placed at each slot assigns an empty slot to each car. The robot is made to run over the tracks by supplying power to the motors fixed in the robot and the movement of robot in the desired direction can be controlled by using servo motors. While retrieval of the vehicle the person is required to swipe the specific RFID, tags assigned to that vehicle, the information collected by the RFID reader is used to retrieve the concerned vehicle and the bill is generated based on its parking time. This process is not only limited for parking the vehicles but also can be used for storage and retrieving of items without any human effort and with minimum errors.Item Microprocessor Based Solid State Nps Relay(2018-10-24T12:22:45Z) Prabhudhi, Sharma; Balaraj, D.BThe negative sequence relay is an important protective device in the power system.It protects from the flow of negative sequence circuits in electrical systems including generators and motors .Negative sequence currents are present due to unbalance in the system.

So gas leakages lead to losses as well as are a threat because they can also lead to fire accidents. Placing sensors at each section of the pipe is very costly.So here we propose an innovative robot that clings on the outer surface of the gas pipe moves with the pipe to check the leakages. The robot consists of the gas sensor that is used to detect gas leakages. As the robot keeps moving along the metal pipe it keeps monitoring for any gas leakage, On detection it uses an interface gps sensor to transmit location of the leakage detected over to the node MCU system., Here we use Node MCU to receive and display the gas leakage alert and location. Thus we have fully automated insect like Robot that moves with the gas pipe and detects gas leakage instantly at a low budget.Item Speed Control Of Induction Motor Using Cyclo Converter With Thyristors(2018-10-22T09:37:14Z) Jayarama, Reddy; Narasimharaju, D LInduction motors are widely used in many industries and domestic applications. They are used commonly in many open-loop control applications due to their cost, size, efficiency, less maintenance, simplicity and easy manufacture. In the past traditional speed control methods were used to control the speed of the DC motors, But DC motors have commutator and brushes which require more maintenance and hazardous. So Induction motors are more preferred in these fields. Since most of the industries use Induction motors, controlling of it plays a major role. This project deals with controlling the speed of Induction Motor using cycloconverter with IOT. The It decodes the signal and generates the pulse width signals which activates its circuit and gives the change in speed of induction motor with respect to the change in firing angle of TRAIC. This way speed can be easily varied and maintained as per the required values. We are not only controlling the speed of the induction motor, we can also provide time to time updation of running motor through the IOT. Which can be displayed through mobile app.. Therefore, this project will be helpful in households, commercial use, industries etc. A cycloconverter is a power electronic device used to convert constant voltage constant Frequency AC power to adjustable voltage adjustable frequency AC power without a DC link. In among all the methods this method is simple, reliable and economical. The various speed of induction motor is obtained by varying the supply frequency by using cycloconverter.Item Design and Fabrication of Solar Powered Semi Automatic Pesticide Sprayer for Agricultural Purpose(2018-10-22T09:30:27Z) Battala Uma, Mahesh; N, Vamsi; Naveena, C; Ravikant, YadavAgriculture has a predominant role in our day to day life. Spraying of pesticides is an important task in agriculture for protecting the crops from pests. The conventional methods were person carrying a sprayer and manually actuating a lever to generate and pump the pesticide through a tube or a mobile vehicle carrying an inbuilt compressor and sprayer unit. Another major drawback in human operated systems is that the operator is exposed to the harmful chemicals while spraying which is extremely detrimental to operator’s health. A solar powered semi-automatic pesticide sprayer model consists of a solar panel, a battery, two DC motors, pump, container, Arduino device which is operated by a wifi ( range is 30 to 50meters) which runs on power source as a DC battery(12V, 1.7Ah). The capacity of the container in the sprayer was designed with 20 liters capacity for an uninterrupted operation of 10 minutes. Analysis of solar radiation data from Bangalore showed that the sprayer can be best operated during 9 AM to 5 PM. The vehicle is powered using an onboard solar powered battery which runs down the running cost. Besides reducing the cost of spraying, there is a saving on fuel as well. The farmers can do the spraying operation without human interference thus protecting them from noxious chemicals.Item Smart Meter for Power Factor Enhancement in Real-Time(2018-10-22T09:24:13Z) Arkdip, Bhowmik; Dibanshu, Kumar; Rajiv, Sampat; Soumya V, KulkarniWith the increase in population, the demand for electricity also increases dramatically.

It is at the heart of our daily lives, vital to economy and society. Agriculture provides most of what we consume and use such as foods, clothes and other materials. Agriculture has been an important part of our lives since the ancient times. We have been able to sustain from the ancient times because of agriculture. We have been developing new ways of agriculture from the past. In the past, technology was not developed that much. Especially agricultural technology was lagging behind than the developments in other sectors. The farmers used do tilling, seeding and irrigation all by themselves in the sunlight. This is a very tedious process. Nowadays, technology has developed a lot. So now it is not necessary to do the tilling, seeding and irrigation by ourselves. Robotics is one of the branches which has been developed. Robotics is a branch of engineering that involves the conception, design, manufacture, and operation of robots. This field overlaps with electronics, computer science, artificial intelligence, mechatronics, nanotechnology and bioengineering. By using robotics, we can do the farming very easily and comfortably. We can sit at a cool place and monitor the robot actions. By use of a remote controller we can monitor and control the robot actions. The robot can be used for seeding, tilling, spraying water and removing various obstacles that are in the way of the robot. The use of robotics will also save us a lot of time which we can utilise for other purposes. The robotics in our project utilises dc motors as driving system, a sensing and receiving system acts as the input and control systemItem Smart Waste Management System(2018-10-22T09:01:02Z) Vishwambhar R, Kulkarni; Prakash, Neupane; Akanksha, Sinha; Esha, YerramsettyThe rapidly increasing population poses several problems which affect the economy and development of India.

They are used commonly in many open-loop control applications due to their cost, size, efficiency, less maintenance, simplicity and easy manufacture. In the past traditional speed control methods were used to control the speed of the DC motors, But DC motors have commutator and brushes which require more maintenance and hazardous. So Induction motors are more preferred in these fields. Since most of the industries use Induction motors , controlling of it plays a major role. This project deals with controlling the speed of Induction Motor using Android phone remotely through Bluetooth Technology. We are using android application which uses Bluetooth to connect to the Bluetooth modem of the control circuit. Bluetooth modem is interfaced with the AVR Microcontroller. The Bluetooth slave receives the commands from the Android phone, then The Bluetooth module sends the signal to the Microcontroller. It decodes the signal and generates the pulse width signals which activates its circuit and gives the change in speed of induction motor with respect to the change in firing angle of TRAIC. This way speed can be easily varied and maintained as per the required values. We are not only controlling the speed of the induction motor, we can also detect the temperature and voltage of it which can be displayed on the android phone. Therefore, this project will be helpful in households, commercial use, industries etc.Item Smart Electric Vehicle(2018-10-22T08:46:00Z) Poornashri, R; Varalakshmi, K; Sangamesh, Biradar; Vijay, Priyan RIn this project, how Electric vehicle can boost charging when it get struck in the middle of the way.

But it is having few disadvantages too like expensive installation and detection of fault location. As it is not visible it becomes difficult to find exact location of the fault. In this Project we will be using two methods which will be very useful to identify the exact distance of fault of underground system from base station. One of the methods is Murray loop method and other one is Ohm’s Law Method. Murray loop method uses the whetstone bridge to calculate exact distance of fault location from base station and sends it to the user mobile. Whereas in Ohm’s law method, when any fault occurs, voltage drop will vary depending on the length of fault in cable, since the current varies. Both the methods use voltage convertor, microcontroller and potentiometer to find the fault location under LG, LL, LLL faultsItem Smart Power Generation on Highways Using Smart Leaves and Piezoelectric Technology(2018-10-17T13:16:45Z) Kiran, M R; Ageesh, A; Harshitha, HHarvesting energy from the environment responsibly is important. Natural trees and plants are doing` this efficiently from millions of years. Our invention is the mimicking of this ingenious concept also referred to as bio mimicry or bio mimetic. The Smart leaves harvest and capture environmental energies like solar radiation, wind and heat and turn this into electricity. The Smart leaves are exploited on both sides, which will incorporate thermo and photovoltaic material for the purpose of converting solar radiation. In addition, we introduce piezoelectric connective elements in the branches that serves for harvesting wind energy into electricity. Kinetic energy is harnessed through movement. The wind produces motion in stems and branches. This motion is collected via piezo electric cells. These cells have semi-conducting devices incorporated in it that convert typical wind energy into electricity. A revolutionary street lighting system with improved management and efficiency can be accomplished. Wireless communication uses Zig Bee wireless devices for more efficient management of the street light system. It uses various sensors to control and guarantee the optimal system parameters. The information is transferred point-by-point using Zig Bee transmitters and receivers. Thereafter it is sent to a control terminal used to check the state of the street lamps and to take appropriate measures in case of failure. The system allows substantial energy savings with increased performance and maintenance. The main purpose of this project is to harvest solar, wind and thermal energy. Energy consumption is reduced by using this system. Photo voltaic cell, thermo voltaic cell, piezo electric cell, IR sensors and microcontroller are the main components of the project.Item Radar Warning Receivers(2018-10-17T12:50:38Z) D V, Tharun; Rohith, P; Sunil, Kumar ARadar is an electromagnetic system used for detection, ranging and location of objects. It operates by transmitting a particular type of waveform, i.e., a pulse modulated sine wave. Radar can be designed to see through those conditions that are impervious to normal human vision, such as darkness, haze, fog, rain and snow. Angular resolution, detection range and Doppler performance are important attributes of Radar. Radars are generally classified on the type of that is being transmitted, namely continuouswave radars and pulse wave Radars. Continuous-wave radars is a short-range measuring set. This kind radars is often used as “Radar Altimeters” to measure the exact height during the landing procedure of an aircraft by employing frequency sweeps and calculating the time taken by the pulse to travel to the target and return. Pulse wave Radar is a 4D radar system capable of detecting both target 3D location as well as measuring radial velocity (range-rate). It uses the Doppler Effect to measure velocity. Digital receivers play an important role in characterizing radar waveforms. Digital receivers are modern devices that incorporate very high speed samplers to digitize the RF waveforms that are received. Digitized RF samples are subjected to digital signal processing algorithms in order to detect existence of a signal and also to measure its parameters namely amplitude, frequency, phase and time of arrival etc. Radars are the main threat against which electronic warfare system works. The task of Electronic Warfare System is to detect radar pulse and take appropriate counter measures. This project aims to simulate a Radar signal, detect and estimate the simulated Radar signal by a Radar Warning Receiver.Item Accelerometer Operated Wheelchair for Physically Challanged People(2018-10-17T12:47:16Z) Anirudh, Dhar; Manish S, Bharadwaj; Adam Derryl, Nazaereth; Shashiraj Kumar, MogerThe main objective of this project is to build a wheelchair that can be controlled by the patient itself. Most of the wheelchairs in the market right now are manually handled by an attendant. Some of the options available in the market are joystick based control which is efficient but not practical for someone with quadriplegia where all of the four limbs are non-functional. So this wheelchair is based on head gesture control where the patient wears a head band and can tilt his head in the required direction and the wheelchair hence moves accordingly. Here we are going to use an accelerometer to read the head gestures made by the user. The accelerometer is placed in the head band . As soon as the patient moves their head and tilt angle is produced by the accelerometer and the signal information is sent to motor via microcontroller reproducing the required motion in the wheelchair.Item Conversion of Single Phase to Three Phase Supply and Speed Control of Three Phase Induction Motor(2018-10-17T12:42:10Z) A N, Sharath; Madiha, Ayub; Sheril, Philip; Srinidhi, MThis paper presents the design and implementation of a voltage source inverter for speed control of an induction motor. A number of pulse width modulation schemes are used to obtain variable voltage and frequency supply from an inverter, but Space Vector Pulse Width Modulation (SVPWM) has advantages such as easier digital realization, better dc bus utilization over the other methods of pulse width modulations. Speed control techniques are generally essential in adjustable speed drive system which requires variable voltage and frequency supply which is invariably obtained from a three-phase voltage source inverter. In recent years, the vector control of induction motor drive is widely used in high performance drive system. It is due to its unique characteristics like high efficiency, good power factor and extremely rugged. This scheme prompts to have the capacity to change the speed of the motor by controlling the frequency and amplitude of the stator voltage, the proportion of stator voltage to frequency (v/f) ought to be kept consistent. In this paper, the conversion of single phase to three phase supply is studied along with v/f speed control of three phase induction motor using space vector pulse width modulation.
