Traffic Controlling System Using RFID

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The technology used is outdated.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.

Automatic Railway Gate Control ECE Project Abstract

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.

Data Acquisition and Controlling using Rabbit Processor

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.

 

Automatic Sowing Machine Project

The growth or development of any nation in the world is purely depends up on the agriculture production. Traditional methods of sowing seeds manually consume lot of time and also it may not be accurate because of human errors.

Maintaining uniformity in seed planting can increase the sowing efficiency, there by to over come all these problems, these days former’s are using automatic sowing machines.

In this regard to enhance the technology in the field of sowing machines, mainly to increase the sowing efficiency, this project work is taken up, which is designed as programmable such that distance between the seeds in ‘X’ and ‘Y’ directions (seeds are supposed to be planted) can be programmed independently.

The Automatic Sowing Machine designed here is quite useful for the large cultivated areas, when compared with man power many acres can be planted with seeds within less time, therefore to prove the concept practically, for the demonstration purpose a proto type module with less speed is constructed with microcontroller unit.

The mechanical transmission section is constructed with four different motors, with the help of one higher rating stepper motor, the entire machine along with seeds container is designed to travel in forward and reverse directions.

Using another higher rating stepper motor, the seeds container arranged over the vehicle at front side is designed to travel in horizontal in both the directions.

Using one reduction gear mechanism DC motor, the seeds container is pulled down for planting the seed through pipe. Similarly using another simple DC motor, the seeds container is vibrated for free movement of seeds through pipe.

In addition to these four motors, a solenoid coil is used to control the seeds. The detailed description of entire process is provided in following chapters.

Remote Operated 3-D Crane For Industries

Crane is a machine that can be used in industries for lifting and lowering the heavy objects and shifts them from one place to another place with in the restricted premises.

In this regard the crane operator has to sit over the mechanism at height, some times due to the physical stress shocks, vibrations, accelerations and un-balanced conditions are taking place such that operators are falling down.

To avoid this problem and to avoid climbing over the crane, the manual operation has been converted to remote operation from the ground thereby improving productivity and safety by dispensing with the need of a ground crew to guide the crane operator from the floor.

Cranes form one of the major items in all kinds of industry. In many places productivity depends on how efficiently the cranes are managed.

Wireless remote control systems have come to acquire a special place in this environment; a wireless remote control system has been commissioned in one of the existing electrically operated traction cranes in the integrated steel plants.

The system installed has greatly increased the operational efficiency of the crane and ensured ‘accident free’ operation. The benefits reaped from the system have compelled other production shops to adopt the new technology.

In this Remote Operated 3-D Crane For Industries project work the system is designed with two main units. The first unit is hand held terminal with inbuilt infrared transmitter is designed with AT89c2051 controller.

The main function of this unit is to collect the operator’s commands from the push keys, the data delivered from the controller is modulated with 38 KHz generated by the timer IC and it is transmitted through infrared LED.

At the other end, a mini model is constructed with mechanical components; all the three movements are produced to make it as 3-D crane through DC motors. The control circuit is designed with ATMEL 89C51 Microcontroller.

The Receiver unit designed with TSOP1738 IR sensor package acquires data from transmitter, based on this data the controller drives the mechanisms through DC motors.
