Design and Implementation of a Practical Aircraft Position and Reporting Identification Beacon (PRIB) in MATLAB

Design and implementation of a practical aircraft position and reporting identification Beacon project is a MATLAB project. Main aim of this project is to develop a new method for tracking aircrafts which does not depend on transponders. In order to develop this system we are using PRIB (practical aircraft position and reporting identification beacon) technology. In order to replace existing transponder system new system should fulfill size, cost, and power efficient and satisfy financial constraints. PRIB technology works on GPS technology in which GPS receiver will track aircraft signals and send to base station which is located at different locations in the form of radio signals. In this paper we provide detailed explanation on design and manufacture of PRIB. Performance is compared between existing transponders and PRIB system and detailed report is provided.

This application uses Gaussian Minimum Shift Keying (GMSK) modulation technique which is one of the secured and efficient modulation techniques used in wireless communication system.

In existing system transponders are used for tracking aircrafts which had shown few issues in recent years mainly at the time of terrorist’s attacks using aircrafts. These transponders can switch off deliberately and stops tracking aircraft for a base station. In order to solve this problem a efficient method need to be developed.

In present system we use PRIB based system which can work without depending on transponders. This system works on GPS technology which is secure and cost efficient.

In this project we provide detailed explanation on topics like aviation survey, global position system and modulation, hardware implementation, software implementations, measurements and experimental results and future development.

Electronic Circuit Breaker System

Introduction to circuit breaker:

Circuit breakers act like switches which detects the faults occurred and stops the flow of current by saving the equipment from voltage overflows and short circuits. It can automatically come back to working when the faults are rectified. Generally the faults in the circuits occur due to in continuous flow of current or by improper arrangement of load elements. The circuit breakers can be designed accordingly for lower voltage circuits and higher voltage circuits. An AT89C52 micro controller is used for monitoring the circuit.

Circuit design and Working:

The microcontroller is fed with the rectified voltage coming from the rectifier. All the load elements are connected to a relay switch.  The microcontroller monitors the voltage level required for the load elements, if it detects any change  the voltage levels to voltage fluctuations  then it automatically drives the relays to turn off. The rectifier bypasses the voltage levels and then the microcontroller again makes the relays turn on. These circuit breakers are mainly used as regulators in power circuits and in battery shunt circuits. The advantage of 89C52 is that it has a 8kb of flash  memory which can be reprogrammed any number of times. A step down transformer is used to obtain the required current for the load elements present.

Advantages:

The circuit breakers are very effective in protecting the load elements from voltage over flows an short circuits. It can automatically switch when the faults occur, where as a fuse cannot switchover. It can be used for lower voltage circuits and higher voltage circuits. It is low cost model when compared to other circuit protecting devices.

Introduction:

Electro active polymers can withstand high present in the deep seas. These polymers are used as skins for devices so that the devices with the pressures in the under water. Electro active polymers have benefits of high coupling efficiency and low cost of availability. The electro active polymer shows good characteristics even under pressures upto 100 mpa. In this paper will see the design and the experimental testing of the polymers.

Brief on electro active polymers:

These are used as transducers for high power sonar’s so as to undergo high pressures. The electro active polymers are prepared from elastomeric actuator. These actuators are formed from two flexible elastic electrodes which sandwich an electrically insulated elastomeric. When the voltage is applied in between the electrodes the get squeezed and expand in area. These have high coupling efficiency because of low visco elastic loss and electrical leakages. It has specific density energy of 21 times that of single crystal peizo electric and can withstand maximum strains.

Experimental testing method:

Here a medium size  water tank is used in which high pressures are generated. Here the maximum pressure can be 159 mpa and has a supply voltage of 2.74 mpa.  It has a flexible transparent membrane which can exert pressure on the polymer. The device is placed in a box and is sealed with silicon oil.  The box is placed in the tank which generates the deep sea conditions. A camera is placed in the tank to monitor the active region. By increasing the pressure levels upto 100mpa the strain a measured. By using a micro meter capler the conditions of the active region for different supplied voltages are measured. As the pressure does not make the polymer to show any changes then we can use it for sonar transducers.

Electricity Generation from Speed Breakers Project Report

Introduction:

In today’s world where every equipment requires electricity for its working, and the demand for the electricity is increasing rapidly. The fossil fuels are getting extinct and there is a need for the search of alternative sources to meet the present electricity demands. In this paper we are going to discuss about one of the available  conventional method for the generation of electricity. All moving vehicles posses kinetic energy, we will use this kinetic energy for the generation of electricity. The entire model is built under a speed breaker and when passes through the speed breaker it generates electricity. We will call this arrangement as power hump. The power generated is stored in rechargeable device for future use.

Working model:

The entire model is placed under the dome of the speed breaker. The springs are placed under the dome and to these spring racks are connected. When the vehicle passes through speed breaker it creates a compression and this makes the springs to move the racks. The racks are connected to the gear unit and a shaft is placed to maintain a uniform motion. A dynamo is used to convert the rotational motion to electricity. The generated electricity gets stored in the batteries for further use.

Advantages and Disadvantages:

This type conventional energy models are very helpful for the generation of electricity with low cost. By the use of fossil fuels the environment gets polluted and by using these conventional methods the nature does not get affected. By using this model we need to look into each time in order to check the disturbances. By using these conventional methods we cannot generate the required power. New methods have to be employed to generate higher voltages. Thus we conclude that these conventional methods can be used for generating electricity to meet the present demands.

Microcontroller Based Dc Motor Speed Control System Project Report

Introduction to speed control technique:

There are several techniques for controlling the speed of DC motor. Some of techniques used are rheostat and chopper control technique which are not that much effective. In this project we are going to employ PWM technique for controlling the speed of DC motor. The AT89C52 microcontroller generates required PWM wave.

Working Design;

A step down transformer is used to obtain the required voltage for the dc motor from the given 230V. A bridge rectifier is used to regulate the voltage generated. Capacitor is used to filter the generated voltage an IC7806 is used to bypass the ripples. The micro controller by using the timer 0 it generates the required PWM waveform.  Two switches are connected to interrupt pins of micro controller, when these are pressed it changes the duty cycle of the dc motor. The generated variable pulse is given to drive the circuit which controls the speed of the motor. The PWM pulse is varied in 10 discrete pulses in the software program. The programming is written in c and keil software is used for compilation.

Testing Process:

To obtain the required speed of the DC motor , certain tests are performed to check the speed of the motor. First the PWM circuit is tested the waveform is tested for each discrete pulse of the output voltages so that the changes occurred can be rectified. Then the speed of the motor is tested for varying voltages and the varying speed of motor is noted for every rise in voltages. Thus we conclude that the PWM technique is the most efficient for controlling the speed of the DC motor.

Reactive Power Static Compensation by Using Condensator Project Report

Introduction to reactive power:

Reactive power does not contribute anything to energy. Due to reactive power the efficiency of the energy systems decreases. The reactive power is the opposition of the load elements. It is consumed or generated by all the elements present in the system. Reactance which contributes the reactive power can be of resistive or capacitive. The paper mainly aims at making the power factor to unity by using the available techniques. If the power factor is more than unity then more power will be consumed by the elements than the required amount which in turn causes power loss which is to be reduced.

Capacitor compensation implementation:

The capacitor compensation method is the efficient method for reducing the reactive power. To overcome the voltage drops and power losses we will use the series and shunt reactive compensation. In the industries all the load elements are inductive so we use capacitive compensation make the capacitor leading and load lagging. In the circuit the capacitor bank is connected parallel to the load and a pic 16f877 is placed to measure the phase difference of the current and voltage. If the capacitor bank is off then there will be a more phase difference between the voltage and current and when it is on their won’t be phase difference which reduces the reactive power.

Advantages of capacitor compensation:

This is the cheapest method for reducing the reactive power.  This is the effective method for keeping no phase difference between the voltage and current. It reduces the power loss in the generation and transmission. By using this we can control the usage of power by the elements which reduce the more power consumption. Thus we can conclude that capacitor compensation method is more advantageous than the synchronous motor method.
