This document describes a remote accident reporting system for highways that uses RF technology. The system aims to monitor accidents on highways and report them. It uses a microcontroller, RF transmitter and receiver, LCD, buzzer, and other components. When an accident is detected by a sensor, the transmitter sends a signal via RF to the receiver. The receiver is connected to a buzzer and LCD to alert authorities and display accident details remotely. The system allows for remote monitoring and control of vehicle accidents on highways.

SEMINOR ON REMOTE ACCIDENT REPORT SYSTEM FOR HIGHWAYS USING RF
AIM The Aim of this is to monitor the accidents which occur on the highways using RF technology. The purpose of this is to report the monitoring section whenever accident occurs on the highways
ABSTRACT In present days Electronic communication takes an important role. In this we are sending information about vehicle accident by using RF communication with the help of Microcontroller. An accident is a specific, identifiable, unexpected, unusual and unintended external event which occurs in a particular time and place, without apparent or deliberate cause but with marked effects, it implies a generally negative probabistic outcome which may have been avoided or prevented circumstances leading up to the accident been recognized, and acted upon, prior to its occurrence.
COMPONENTS  Microcontroller  Max 232  Buzzer  Transformer  H-Bridge  LCD

RECEIVER SECTION MICRO CONTROLLER Power supply LCD AT89S52 BUZZER HT12D RF decoder RECEIVER
PORT 1: Motors are connected to port one of micro controller through two h bridges. The two h bridges are connected to P1.0, P1.1, P1.2 and P1.3 respectively PORT 3: Switch is connected to P3.7. It is acts like an accident identification sensor. PORT 2:  Port 2 can act as both input as well as output port. The microcontroller port 2 pins are connected to the transmitter circuit. We are using HT12E IC which is a 18 pin Ic.
PORT 0: This port 0 can act as both input as well as output port. In this port zero is connected to lcd. The data pins of lcd is connected to data pins of lcd. PORT 2:  Port 2 can act as both input as well as output port. The microcontroller port 2 pins are connected to the receiver circuit. We are using HT12D IC which is a 18 pin decoder. BUZZER: Buzzer is connected to the port p3.0.
Micro Controller The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry- standard 80C51 instruction set and pin out. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer.
RF Transmitter 315/434 MHz ASK TRANSMITTER Here in this the RF transmitter module is not directly connected to microcontroller. An Encoder is connected between the RF module and the controller, in order to encode the data for efficient transmission of the data.
RF Receiver 315/434 MHz ASK RECEIVER In this RF receiver is connected as shown in the schematic. The DATA pin is connected to the decoder HT648L which decodes the received signal and gives to the microcontroller.
Power Supply The power supplies are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronics circuits and other devices. A RPS (Regulated Power Supply) is the Power Supply with Rectification, Filtering and Regulation being done on the AC mains to get a Regulated power supply for Microcontroller and for the other devices being interfaced to it.
H-BRIDGE:  H-bridge is to construct with transistors and Motor. It is used to control the vehicle.
Buzzer Buzzer is for alarming purpose ,when ever the system will find any accident occurrence the buzzer will buzz.
APPLICATIONS  Car security system  Wireless security system  Automation system  Remote keyless entry Advantages To control the accidents
CONCLUSION The “REMOTE ACCIDENT REPORT SYSTEM FOR HIGHWAYS USING RF” has been successfully studied, Integrating features of all the hardware components used have developed it. Presence of every module has been reasoned out and placed carefully thus contributing to the best working of the unit.
