INTELLIGENT AMBULANCE FOR CITY TRAFFIC AND GSM TO SENT THE
STATUS OF THE PATIENT TO THE HOSPITAL
ABSTRACT:
The main aim of this project is develop an intelligent ambulance which will reach the hospitals without any problem in heavy traffics.
INTRODUCTION:
This particular project is designed for the cities with heavy traffic. Eg: In Bangalore the roads are full jammed every time. Most of the time the traffic will at least for 100meters .In this distance the traffics police can¶t hear the siren form the ambulance .so he ignores this .Then the ambulance has to wait till the traffic is left. Some times to leave the traffic it takes at least 30 minutes .So by this time anything can happen to the patient .So this project avoid these disadvantages. According to this project, if any ambulance comes near or when the ambulance at emergency comes to any traffic post the traffic signals automatically stop the signals and give green signal for this ambulance.

COMPONENTSUSED:
Power Supply - 12V/1A DC
Micro controller ± AT89C51
Buzzer - 5Vdc
Light Emitting Diode (LED)
RF transmitter & receiver
IR Transmitter and Receiver

SOFTWARES USED:
Keil uVision3
Embedded c

WORKING PRINCIPLE:
When the ambulance at emergency comes to any traffic post the traffic signals automatically stop the signals and give green signal for this ambulance.
The ambulance carries an IR transmitter and IR receiver will be there some few meter before the signal. The receiver will receive the signal and the module will send the command turn on green through the RF and every traffic post will have an RF receiver. So whenever the ambulance comes near the traffic, the ambulance will transmit a code say ³emergency´ the receiver will receive this signal .Then it immediately switch off the other signals that is it make all the signals red and later make this particular direction signal green. So by doing this the ambulance can go without any problem.

2.1 Embedded Systems
An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions, often with real-time computing constraints. It is usually embedded as part of a complete device including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, can do many different tasks depending on programming. Embedded systems control many of the common devices in use today.

Since the embedded system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product, or increasing the reliability and performance. Some embedded systems are mass-produced, benefiting from economics of scale. Physically, embedded systems range from portable devices such as digital watches and mp4 players, to large stationary installations like traffic lights, factory controllers, or the systems controlling nuclear power stations. Complexity varies from low, with a single microcontroller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or enclosure.

In general, "embedded system" is not an exactly defined term, as many systems have some element of programmability. For example, handheld computers share some elements with embedded systems ² such as the operating systems and microprocessors which power them ² but are not...
