The main intention of this project is to find the accident spot at any place and intimating it to
ambulance through the gps and gsm networks. Now-a-days, it became very difficult to know
that an accident occurred and to locate the position where it has happened. It’s very difficult for
the lives of victims until anyone noticed and informed it to the ambulance or to any hospital
and if it occurs in remote areas there will be no hope to survive. To overcome these, gps and
gsm technologies are used. The gps based vehicle accident identification module contains a
vibrating sensor and a gps modem connected to the microcontroller. When an accident occurs
,the vibration sensor gives the signal to the microcontroller, which sends the information to the
control room through gsm network.
Embedded ‘C’ or
Embedded systems are electronic devices that incorporate microprocessors with in their implementations. Embedded systems designers usually have a significant grasp of hardware technologies. They use specific programming languages and software to develop embedded systems and manipulate the equipment. Embedded systems often use a (relatively) slow processor and small memory size to minimize costs. An embedded system is a special-purpose system in which the computer is completely encapsulated by or dedicated to the device or system it controls. Unlike a general-purpose computer, such as a personal computer, an embedded system performs one or a few pre-defined tasks, usually with very specific requirements. Since the system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product. Embedded systems are often mass-produced, benefiting from economies of scale.
Global System for Mobile Communication (GSM) is a set of ETSI standards specifying the infrastructure for a digital cellular service. GSM (Global System for Mobile communication) is a digital mobile telephone system that is widely used in many parts of the world. GSM uses a variation of Time Division Multiple Access (TDMA) and is the most widely used of the three digital wireless telephone technologies (TDMA, GSM, and CDMA). GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. GSM operates in the 900MHz, 1800MHz, or 1900 MHz frequency bands. GSM (Global System for Mobile communications) is the technology that underpins most of the world's mobile phone networks. The GSM platform is a hugely successful wireless technology and an unprecedented story of global achievement and cooperation. GSM has become the world's fastest growing communications technology of all time and the leading global mobile standard, spanning 218 countries. GSM is an open, digital cellular technology used for transmitting mobile voice and data services. GSM operates in the 900MHz and 1.8GHz bands GSM supports data transfer speeds of up to 9.6 kbps, allowing the transmission of basic data services such as SMS.
Everyday, millions of people are making phone calls by pressing a few buttons. Little is known about how one person's voice reaches the other person's phone that is thousands of miles away. Even less is known about the security measures and protection behind the system. The complexity of the cell phone is increasing as people begin sending text messages and digital pictures to their friends and family. The cell phone is slowly turning into a handheld computer. All the features and advancements in cell phone technology require a backbone to support it.
