Accident statistics Buzzer during any accident
[attachment=48846]
Accident statistics:
• India's road accident record:
16 % of the world's road accident death happens in India, while India has only 1 % of the world's road vehicles
• SO THERE IS A 24/7 EVERYDAY ON INDIAN ROADSWHICH IS A BIGGER KILLER?
• The Solution:
Our system aims at providing help to the injured in road accidents as fast as possible, thereby increasing the victim’s survival chances.
• Proposed System:
In our proposed model we have 3 modules, they are as follows
Vehicle side module
Road side module
• Control room side module:
The vibration sensor senses the vibration and sends the signal to the microcontroller, which compares the input from the vibration sensor with the fixed delay of 30 seconds (delay period of switch when the switch is pressed then the output of the microcontroller is 0, when the switch is not pressed then the output is 1.
If the output is 1 then the IR transmitter transmits the signal to the road side IR receiver which is placed along with the sign board (Km board, lamp post, etc). Each IR receiver will have a different frequency so that the accident spot can be found easily by the patrol.
PREVIOUS SYSTEM:
In the previous system only the buzzer will raise during any accidents , and hence the patrol can not exactly locate the accident spot .
PROPOSED SYSTEM:
In our proposed model we have three modules they are as follows
1. Vehicle side module.
2. Road side module
3. Control room side module.
OSCILLATOR CIRCUITS:
The 8051 requires an external oscillator circuit. The oscillator circuit usually runs around 12MHz, although the 8051 (depending on which specific model) is capable of running at a maximum of 40MHz. Each machine cycle in the 8051 is 12 clock cycles, giving an effective cycle rate at 1MHz (for a 12MHz clock) to 3.33MHz (for the maximum 40MHz clock). The oscillator circuit generates the clock pulses so that all internal operations are synchronized.
TRANSMITTERS AND RECEIVERS:
IR TRANSMITTER:
• Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400-700 nm), but shorter than that of terahertz radiation (100 µm - 1mm) and microwaves (~30,000 µm).
• A transmitter can be a separate piece of electronic equipment, or an electrical circuit within another electronic device. A transmitter and receiver combined in one unit is called a transceiver.
• The transmitter combines the information signal to be carried with the radio frequency signal which generates the radio waves, which is often called the carrier. This process is called modulation. The information can be added to the carrier in several different ways, in different types of transmitter.
• Symbol and operation of IR transmitter is very similar to ordinary LED, Light Emitting Diode.
• LED emits ordinary light. IR transmitter generates infrared. IR transmitter is made up of Gallium arsenide.
• If we pass the current to gallium arsenide it produces IR rays.
IR RECEIVER:
• IR receiver is having reverse characteristics of the IR transmitter.
• IR Receiver will conduct as long as the rays fall on it.
• In our project we are going for IR transmitter and receiver, but in real time instead of IR, wireless is to be used.
• Since IR can be used only during proper alignment position.
WIRELESS TRANSMITTER:
• Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path.
• The first wireless transmitters went on the air in the early 20th century using radiotelegraphy (Morse code). Later, as modulation made it possible to transmit voices and music via wireless, the medium came to be called "radio." With the advent of television, fax, data communication, and the effective use of a larger portion of the spectrum, the term "wireless" has been resurrected.
CONCLUSION:
To minimize the deaths and severe conditions due to accidents the wireless technology are used where the immediate action would be take place by the ambulance/police service which might reduce the severity.
