I am subha rani.I am the B-TECH student in stream of ECE.I want to do the ACCIDENT IDENTIFICATION USING RF as my mini project.I want the full documentation about this project.I am expecting a quick responce from you.And I have the ABSTRACT for the project ACCIDENT IDENTIFICATION USING RF.
Please send the documentation as early as possible.
An RF tag transmitter shall be provided to each vehicle for vehicle identification. In the event of an accident, you will transmit your identification. On the receiver side, the RF module will signal the microcontroller. The microcontroller is responsible for making the decision here and the informant to the service person. Give the data to LCD, Buzzer and LED. We will also use four LEDs to show accidents for immediate action.
These sensors are connected to port p3.4 and port p3.5
The pin 40 is connected to the positive supply. In this project we offer a power supply of 5 volts DC. This power supply is a truly regulated power supply. Pin No. 20 is connected to the negative supply. Here we supply a negative voltage on this pin. The crystal is connected to the pins 18 and 19 of the microcontroller. The crystal provides a clock signal to operate the vehicle and process all the internal requirement of the circuit. We use two sensors and these two sensors are connected to the p3.4 and p3.5 of the microcontroller. For the regulated power supply we use ic 7805 as a regulator to provide a fixed power supply of 5 volts.
In this project we will make a transmitter for RF data transmission. Pin # 1 on the RF module tx is grounded. Second is for data, third for VCC and fourth for antenna Transmitter.
Transmission of the entire project in a few steps:
RF Transmitter
• RF module
• Encoder circuit
RF Receiver
• Receiver Rf
• Decoder
• Microcontroller circuit
• Visual indication - LCD and LEDs
• Audio alert buzzer
