The thorough research on the current transportation system results in many problems of traffic signal scheduling, and maintaining the unique identity of a vehicle.

Since the traditional system on traffic controlling is predetermined, it is important to dynamically maintain the traffic controlling system. We use the RFID technology and the scheduling techniques which serves this purpose.

RFID system has RFID Reader and Tags which are used for the data collection from the vehicles, which has unique tag identity. Based on the database the number of vehicles in a particular region or the intersection can be calculated.

The database consists of the minimum attributes like the unique id of the vehicle, type of vehicle i.e., the two-wheeler or the four-wheeler, location of the vehicle, position of the vehicle, number of times the vehicle identified in that particular region.

Scheduling technique used is Oldest Job First (OJF) and Delay scheduling which are merged together and a hybrid scheduling algorithm is generated, where OJF is used for the static update of the platoon signal whereas the Delay scheduling is used in maintenance of the platoon dynamically.

Together merged the scheduling gives an appropriate and efficient output.

KEYWORDS: RFID, Delay Scheduling, Oldest job first Scheduling, Hybrid Algorithm.

Traffic control system is always a major problem which is not completely solved. so to overcome he problems of present traffic controlling system ,our project is proposed which is based on Rfid technology.

EXISTING TRAFFIC CONTROL SYSTEM

The traffic control system is static.
There are lots of congestion problems at intersections.
The technology used is outdated.
We also have a problem of theft of vehicles and forging the identity of vehicles.
In fact according to a survey of KPMG Indian Fraud survey 65% of crimes were theft of vehicles.

PROPOSED SYSTEM

The proposed system overcomes every problem that are faced in the existing system.
It uses RFID technology.
RFID acronym Radio Frequency Identification.
It is a form of wireless communication which uses radio waves to identify and track objects.
Identify objects without direct line-of-sight.
Identify many objects simultaneously.
Identify objects within a particular distance i.e., few centimetres to several meters and up to kms depends on the frequency of the RFID reader.
In the project RFID Reader and RFID tags are used for data collection.

MAIN OBJECTIVES

It can be used by cops for the unique detection of the vehicles as RFID is used.
For efficient and dynamic traffic control.
For maintaining less traffic congestion problem.
For prediction of number of vehicles in a particular region.

TECHNIQUES

For maintaining the dynamic behavior of the traffic signal, we use the scheduling techniques like OJF (Oldest Job First) and delay scheduling .
Delay scheduling is to maintain the recently added jobs delay scheduling algorithm is called, it helps in making the job wait for a limited amount of time.
OJF is used for the dynamic implementation and delay scheduling is called with in the OJF for the static implementation controlling which is known as hybrid scheduling.

AIM:

The main aim of this project is to design a Wireless Desktop Operation for PC using IR Remote

PURPOSE:

The purpose of the project is to do all the operations of the mouse wirelessly.

2. RECEIVER SECTION:
3. POWER SUPPLY:

DESCRIPTION:

In present days the use of computer is growing rapidly with the boom in IT field. There is a great impact of IT field. And day by day, the need for computations with great speed and accuracy also increased the usage of computers.

Computer became a basic amenity for students. Students are using computers for their academic work. The other applications apart from above mentioned are to play audio and video files etc. Even kids became regular users of computer due to their passion towards games.

But sitting in front of monitor for hours and hours has a great impact on our eyes as well as body. So here is an approach to do all these mouse operations and some of the keypad operations remotely by using IR communication.

The present project will do all the operations of the mouse as well as some functions of the Keyboard like Enter, Windows button and Direction keys as well. Just use your computer as a TV with the help of this remote.

In this we are going to use IR communication and .NET as main platforms. Here the signals of our remote are transmitted to the receiver section which includes microcontroller, which is near the PC.

The signals which are received by the controller are sent to the PC via serial communication through DB-9 connector. And finally the operations are all done by the COM controls by the use of .NET.

The .NET is used for the front-end application development. Here we are using the COM controls to interface the controller. The block diagram of the present project including the transmitter and receiver section along with PC is shown below.

Traffic is one of the major problems now a days. In the same way the crossing of railway gates is also a tedious job for normal people. They have to wait for a long time even before and after arrival and departure of the trains.

In rapidly flourishing country like India, accidents in the unmanned level crossings are increasing day by day. At present, in level crossings the railway gate is operated normally by a gate keeper after receiving the information about the train’s arrival.

Instead of waiting such a long time at the railway gates and to avoid accidents in level crossings a project is proposed that controls the gate automatically with out involvement of the railway level crossing gate keeper. It can also implemented in unmanned level crossings at remote areas.

The Automatic Railway Gate Control application part deals with the design the power supply section which converts 230V AC into 5V DC by using 7805 voltage regulator and selection of AT89S52 Controller for inbuilt ISP option.

The train arrival and departure  would sensed by 2 sensors. When ever the first sensor senses the train is near by means it sends a signal to preprogrammed micro controller which the railway gate is controlled by means of a dc motor.

Then the gate closes and opens when the second sensor senses the train departure. The Automatic Railway Gate Control Abstract deals in detail the circuit description along with the component description, required Software and Coding.

Abstract

The main aim of the Data Acquisition and Controlling using Rabbit Processor project is to develop a web based Data acquisition and controlling system using Rabbit processor for  the infant care unit,where the  temperature,humidity and light intensity are monitored and controlled continuously.

In this project we monitor the status of the infant care unit.The humidity,temperature are monitored continously and are sent to pc via internet.

The temperature is controlled by changing  the intensity of the light. If the temperature  is high then the intensity of the light is made less by decreasing its intensity  automatically and vice versa.

The temperature and humidity sensors measure the temperature and humidity in the room and sends the values to the rabbit processor. The processor sends the data received to pc through the ethernet port.

The processor maintains the intensity of the light based on the temperature value in the room. If the temperature is high then the intensity of the light is made less and vice versa.
