Introduction-

Excessive or inappropriate speed is a significant factor in serious road accidents. Road safety authorities around the world devote considerable resources to addressing the speeding problem particularly compliance with speed limits. One countermeasure that is gaining increasing attention is the use in vehicle technology to assist drivers keep to speed limits or even prevent the vehicle from exceeding speed limits on all roads at all times. This is known as Intelligent speed Adaptation.

Intelligent speed Adaptation (ISA) is the generic name for advanced system in which the vehicle knows the speed limit for the road currently being travelled on. That Information can be used to display the current speed limit inside the vehicle and warn the driver when he or she is speeding. The technology is of interest because of the known relationship between speed and risk of an accident and also because of the relationship between speed and injury severity in an accident.

Construction And Working

4.1Description of Working Model

For showing the implementation of our concept of project, we construct of working model in which we use one transmitter card, a receiver card and a toy car. The transmitter and receiver card is same as for practical system implementation. The only difference lies between the practical vehicle system and our used toy car the toy car we use here is a gear car which uses dc motor for its movement. For transferring of signals of information between transmitter and receiver, we use RF communication through RF module. So the whole system is designed around two parts

1.Transmitter.

2.Receiver

4.2Construction of working model Transmitter

Major Component of the Transmitter is

1.LCD display

2.4 x 4 keyboards

3.RF Module

4.Microcontroller

5.Power Supply Section

1. Lcd. Display: - It has 16x2 LCD display to see the status of the transmitter.

2. 4x4 keyboard: - it has 16 switch key board to set the varios parameter. Such as:-

Switch1:- To set the speed limit of speed zone. When this switch is press Speed setting screen is shown. As follows Speed=10%.

Switch2:- To increase the speed limit, for e.g. If this press Speed=12%.

Switch3:- To decrease the speed limit, for e.g. If this press Speed=10%.

Switch4:- To save the speed limit and exit the screen, for e.g. If this press. Return to home screen. RKDFCE BHOPAL

Switch5:- When this switch is press system then you set the sending message. Shows you a previous message. Message=Rtn(Right turn)

Switch6 and 7:- by using this u can change the message.

Message=Rtn(Right turn)

Message=Ltn(left turn)

Message=Brd(Bridge)

Message=nhn(no horn)

Message=wip (work in progress)

Switch8 :-by using this u can save the message for transmission and exit you home screen.

Switch9:-by using this u can select the mode of system.By default it will shows the previous save mode. And remain in this.

Switch10:-by using this U are in transmiiter mode.

Switch11:-by using this U are in Remote mode.

Switch12:-by using this U are in save the state if power is off.

Switch13:-Only work in remote mode By using this increase the speed of car remotely.

Switch14:-Only work in remote mode By using this decrease the speed of car remotely.

Switch15:-Only work in remote mode By using stop the car.

Switch16:-Exit without saving in any mode.

3).Rf module:-

This module is used to transfer data in rf. Form.

This module is working on a 433 mhz. and Ask modulation is used. And support the data below the 1200 bps.

4. Microcontroler. :-In this system we are using mc of microchip company which is PIC16f877a. which is RISC based controller. Only has 35 set of commands set. Has various paripherel inbuilt such as USART,TIMER,ADC,SPI,I2C,EEPROM and has 8k of program memory and also has various features.

5). Power Supply: - In the whole system we are using +5v regulated power supply. It is obtained by the 230v ac.

This section is covered by these parts:-

12 v step down transformer (500m amp)

Full wave rectifier.

Filter.

linear regulator.

a. 12 v step down transformer(500m amp):- Step down transformer is used to convert 230v ac to 12v ac. With current rating of 500 mump.

b. Full wave rectifier: - The full wave Bridge rectifier is used to convert 12 ac to the pulsating dc which is equal to average value.

c. Filter: - Filter is a used to convert pulsating dc to constant dc. It may me capacitor, RC network, inductance. depends upon the current foll
