    wireless traffic density control using sensor wireless traffic density control using sensor Presentation Transcript

    • V.SATHISH VELAMMAL INSTITUTE OF TECHNOLOGY CHENNAI
    • INTRODUCTION  Due to the heavy traffic in the road many people are suffering. Even though there is traffic signal available at various places it is not easy to control the crowd. In order to avoid traffic problem heavily on the road, we designed and developed a system so called as traffic density controller with wireless control.
    • TRAFFIC DENSITY
    • BLOCK DIAGRAMTransmitting data Transmitting data
    • DESIGN COMPONENTS  ATMEL 89C51 MICROCONTROLLER  IR TRANSMITTER AND RECEIVER  ENCODER WITH RF TRANSMITTER  DECODER WITH RF RECEIVER  LIQUID CRYSTAL DISPLAY  RELAY DRIVER CIRCUIT  POWER SUPPLY CIRCUIT
    • single chip microprocessor system The microcontroller contains full implementation of a standard MICROPROCESSOR, ROM, RAM, I/0, CLOCK, TIMERS, and also SERIAL PORTS. system as a low cost product WHY MICROCONTROLLER?
    • WHY ATMEL 89C51 MC? 89c51 have RISC architecture and contains less no of opcodes which are easy for programming. so it is preferred than 8051.  Flash EPROM provided with memory not only RAM but also ROM parallel and serial port (Universal Asynchronous Receiver/ Transmitter)
    • ADVANTAGES OF INFRARED Electrical devices do not interfere with infra red transmission.  infra red technology are its simple and extremely cheap senders and receivers which are integrated into nearly all mobile devices No licenses are needed for infra red technology and shielding is very simple the transmission of infra red light (e.g., at 900 nm wavelength).
    • IR TRANSMITTER  Symbol and operation of IR transmitter is very similar to ordinary LED IR transmitter generates infrared. IR transmitter is made up of Gallium arsenide. If we pass the current to gallium arsenide it produces IR rays. Current applied to the sensor is directly proportional to the rays emitted though IR transmitter can withstand up to 35mA, we have used 5mA due to shortest distance. If the distance is more we have to increase the current flow to the transmitter
    • IR RECEIVER This circuit is mainly used to for counting application Since IR can be used only during proper alignment position IR receiver is having reverse characteristics of the IR transmitter IR Receiver will conduct as long as the rays falls on it.
    • ENCODER WITH RF TRANSMITTER In this circuit HT 640 is used as encoder We are going to implement 433.92 MHz RF transmitter to our project for effective, quick, reliable type and its operated at 12v dc. This can be switched by relays. Mixer encoder This is to mix carrier and modulation system and encoded for signal transmission
    • DECODER WITH RF RECEIVER In this circuit HT648 is used as decoder Wireless receiver is having reverse characteristics of the wireless transmitter  The 318 decoder are a series of CMOS LSIs for remote control system application  proper operation a pair of encoder/decoder pair with the same number of address and data format should be selected.
    • FUNCTIONAL ARCHITECTURE
    • OPERATION Here we are using two modes, namely 1. Automatic Mode 2. Manual mode .
    • AUTOMATIC MODE  The IR sensor senses how many vehicles are crossing on the corresponding side. All the sensors send the corresponding output signal to microcontroller.  The LCD display is used to indicate the side through which the vehicle has to be passed  The microcontroller compares which road side is the highest density (i e, more vehicles) and it delivers the corresponding signal to LED driver circuits. The LED driver circuit enables the LED to display for particular time depends on traffic density.
    • MANUAL MODE  When this type of system is followed, we are sure that we can control the traffic to certain extent to certain extent.  From this system, we can free up the traffic in the VIP’s traveling road by wireless.  There is a key pad connected remotely to control that. For each key present in that the corresponding road will be free up and other roads are blocked.
    • ADVANTAGES  Avoids wastage of time due to the traffic  Fully automatic  Low power consumption  It provides the easy access in the traffic light  Low cost to design the circuit, maintenance of the circuit is good  By using this microcontroller IC we can create many more control to the appliances  Easy convenience to handle
    • APPLICATIONS  The project is mainly used in the traffic signals  It is a boon to the automobiles so that there are many advantages  It can be implemented on some other areas where we need wireless transmission  It is implemented in the traffic signals also for monitoring the vehicles if there is any misuse it will automatically know
    • FUTURE SCOPE
    • CONCLUSION  The project may be very well used in where the traffic signals is kept and in many other places where we need to full fill the need of the automation. In the future we implement the project’s idea in the industries.  By using this project in future we can know traffic density in the city and so that remedies can be made according to that.
