  b) Background

 CE 1.1 The project entitiled 'An intelligent Lighting System for Exhibition Application' contains   narration of the first career episode. I worked in this project for last one year. The fame and         popularity as well as the successful execution of this project was emergent for the completion of my   Bachelor in Technology in Electronics and Communication from Jawaharlal Nehru Technology    University, Hyderabad, Telangana, India. The location of the project was the college with    appropriates technology and project labs. I worked on the project having group member only two. 

CE1.3 The main aim of the project is to design the smart lightening system. The main property of this system would be energy efficient and would perform autonomous operation. From some case studies details, if there large group of lighting used in a building it was tough to control energy wastage. I prompt to use current smart lighting technologies available in the market along with their product features and advantages. I spend lots of my time on researched for implementing the components in the smart lighting system design projects.

CE1.4 I studied Modular Intelligent Control System(MICS) for smart lightening system, which is hot topic especially in Engineering Field, where most of the researcher and engineer are involving themselves in finding a solution to reduce the energy usage at the same time increasing their products efficiency. Mainly, it is used in home appliances, street lamp, industrial automation, aeronautics and automobiles etc. It uses the controller system which is the integration of devices to incorporate functions of sensing, actuation and control. This system is capable of describing and analyzing a situation and takes the decisions based on predefined conditions and C or assembly language programming was used for programming.

CE1.5 For the project execution I performed several different tasks to do this some of them are listed below:

·        Identify all the work items that are part of my project to generate some idea of the project: to scratch out the concept and agree the it will be taken in further

·        Planning of the project based on the requirement analysis of the project.

·        Designing of the appropriate diagram showing the    workflow of the project.

·        Preparing the associated essential documents like reports of the project.

·        Finally, analyzing the outcomes of the projects regarding all the previous research works.

  

   c)  Personality Engineering Activity

CE1.6 First of all I started my project by collecting the details from the from the literature review of the different case study related to my project. I found that smart system are autonomous and the ones which makes human life more easy. In order to reach to the optimal result, the system performed in a continuous manner. I visited the university’s library many times and reading newspapers article for the latest article and journals. I also scrolled internet to get more details.

CE1.7 One day I went to exhibition hall and there was some zones in the hall which is the perfect example of smart lighting. In that hall among the different zones, zone 1 is the lighting area for the hall whereas other zones (zone 2 to zone 4) were the groups of the lighting for the student area. After studying the environment I started finding the possible problem that could in the exhibition. After studying the problem I made three different cases for the resolution of the problem,

CE1.8 In case 1, I observed that all the lights in the exhibition hall were still turned ON if hall was not occupied too. In case 2 of the example, when small number of students appeared in the class than all the lights in zone 1 to zone 4 were still turned ON. Finally, in case 3, due to differences in the teaching modes exhibition was having hard time whenever they switched their teaching mode because they need different lighting environment.

 CE1.9 For solving the problem faced by the exhibition hall, I conclude to build an energy saving lighting system with integrated sensors and controllers. I designed the smart lighting system which can be controlled using the internet to adjust lighting brightness and schedules. Additionally, also designed the lighting system including high efficiency fixtures and automated controls that make adjustments based on conditions such as occupancy or daylight availability. I built the MICS in different modules and categories into two types: input module and light module.

CE1.10 I used motion detector, an electronic control unit and a controllable switch/relay. The detector senses and visualize the motion and determines the availability of occupants in the space. I prepared a smart lamp monitoring to control the status of the street lamps and forward monitored result to the control station. To study the work flow of the smart lamp I prepared the simplified block diagram of the complete smart lamp monitoring system. Different module used are resistor module, transmission module, and microprocessor module inside the lamp. The lamp module and control center communicate through wireless using Xbee.

CE1.11 Installation of LDR is done on the top of the street lamp to check the day/night status. Similarly another LDR is placed under the street lamp to monitor and check the lamp health status. In order to process the data the results of the LDRs are sent to microcontroller and then sent to the transmission module. Wireless Xbee is used to transmit the data through wireless to the control center in the transmission module.

CE1.12 After the detailed study, I designed the prototype for the lecture hall where it was able to control both lighting system and HVAC (Heating Ventilation and Air Conditioning) system. In addition both system are dependent on one another i.e. they are integrated. Four 15W incandescent lights are there in the surface of the illustrated lecture class room where each light represented one zone of area in the lecture hall. Three LED lights which represents the signal light of the computer, projector and OPH and turn ON any lights of this would represent the signal of the current usage of the respective equipment. Similarly, one RFID reader are present in one of the lecture hall area.

CE1.13 One of the enclosure is containing incandescent bulb where multi sensor is installed. The main function of the incandescent bulb is to control the ambient lights inside the enclosure by switching ON/OFF. The top of the enclosure was opened for the purpose for the outer light source by lighting up inside the enclosure. I always followed academic and professional honesty as well as integrity in publishing my own original work.

CE1.14 I actively participated in the documentation of the project too. Based on the previous analysis such as literature review, preliminary findings from the experiment and scheduled of work planned in Gantt chart I produced a mid- level project progress report. Then I submit the report to the school faculty and attained the positive feedback. To sum up, I prepared a Power Point presentation in English to demonstrate my all work in thesis seminar to all of other academic staff and students.

CE1.15 For executing the good project completely there should be good coordination between the team members and all sorts of the conflicts should be avoided. Every member should follow the university ethics and academic and I also so the same in my thesis project.

D) Summary

CE1.16 Since the project requires comprehensive demonstration of managerial, technical, and professional skills in decision making, planning, executing and reporting so this project is very useful and significant for my engineering course. I expertise myself on the project management skills as well as in strengthening the research skills. I learnt different techniques of the data collection its integration and synthesis of the vital technical details from all resources to produce novel design in the project. Finally it was the great opportunity for me to show the inner knowledge of me and also improve the communication and coordination skills on me.
