Global system for mobile communication based car

The advent of technology has also increased the traffic hazards and the road accidents take place frequently which causes huge loss of life and property because of the poor emergency facilities. Our project will provide an optimum solution to this draw back. An accelerometer can be used in a car alarm application so that dangerous driving can be detected.

It can be used as a crash or rollover detector of the vehicle during and after a crash.

  • We found out that there is need of some system;
  • This paper is useful in detecting the accident precisely by means of both vibration sensor and Micro electro Mechanical system MEMS or accelerometer;
  • Typically, while one instruction is being executed, its successor is being decoded and a third instruction is being fetched from memory.

With signals from an accelerometer, a severe accident can be recognized. According to this project when a vehicle meets with an accident immediately Vibration sensor will detect the signal or if a car rolls over, and Micro electro mechanical system MEMS sensor will detects the signal and sends it to ARM controller. Then after conforming the location necessary action will be taken.

This paper is useful in detecting the accident precisely by means of both vibration sensor and Micro electro Mechanical system MEMS or accelerometer. Life of the people is under high risk.

This is because of the lack of best emergency facilities available in our country. An automatic alarm device for vehicle accidents is introduced in this paper.

Gsm and gps 2017 IEEE PAPER Global System for Mobile communications and Global Positioning System

This design is a system which can detect accidents in significantly less time and sends the basic information to first aid centre within a few seconds covering geographical coordinates, the time and angle in which a vehicle accident had occurred. This alert message is sent to the rescue team in a short time, which will help in saving the valuable lives. A Switch is also provided in order to terminate the sending of a message in rare case where there is no casualty, this can save the precious time of the medical rescue team.

When the accident occurs the alert message is sent automatically to the rescue team and to the police station. The message is sent through the GSM module and the location of the accident is detected with the help of the GPS module.

  • In this system simple and cheaper vehicle tracking is implemented with the help of Global Positioning System GPS , and free download Abstract;
  • In todays world, women safety has become a major issue free download Abstract-Proposed automated system used an important technique to avoid the accident from inbrite and drowsy peoples [1];
  • Pipeline techniques are employed so that all parts of the processing and memory systems can operate continuously.

The accident can be detected precisely with the help of both Micro electro mechanical system MEMS sensor and vibration sensor. This application provides the optimum solution to poor emergency facilities provided to the roads accidents in the most feasible way.

Automatic Vehicle Accident Detection and Messaging System Using GSM and GPS Modem

Complete layout of the whole set up will be drawn in form of a block diagram. A piezoelectric sensor will first sense the occurrence of an accident and give its output to the microcontroller. The GPS detects the latitude and longitudinal position of a vehicle. The latitudes and longitude position of the vehicle is sent as message through the GSM. Whenever an accident has occurred the position is detected and a message has been sent to the pre-saved number.

GSM (Global System for Mobile communication)

It has its own deterministic character. Hence no need to waste time by manual operation and transportation. Hence it is considered as highly efficient communication through the mobile which will be useful in industrial controls, automobiles, and appliances which would be controlled from anywhere else.

It is also highly economic and less expensive; hence GSM is preferred most for this mode of controlling. Tracking systems enable a base station to keep track of the vehicles without the intervention of the driver where, as navigation system helps the driver to reach the destination.

Whether navigation system or tracking system, the architecture is more or less similar. When an accident occurred in any place then GPS system tracks the position of the vehicle and sends the information to the particular person through GSM by alerting the person through SMS or by a call.

The research work is going on for tracking the position of the vehicle even in dark clumsy areas where there is no network for receiving the signals. Hence with this project implementation we can detect the position of the vehicle where the accident has occurred so that we can provide the first aid as early as possible.

  • It is also highly economic and less expensive; hence GSM is preferred most for this mode of controlling;
  • The ARM7TDMI-S processor also employs a unique architectural strategy known as Thumb, which makes it ideally suited to high-volume applications with memory restrictions, or applications where code density is an issue;
  • And in coming few years the cities will become developed and smart one;
  • When the accident occurs the alert message is sent automatically to the rescue team and to the police station.

This simplicity results in a high instruction throughput and impressive real-time interrupt response from a small and cost-effective processor core. Pipeline techniques are employed so that all parts of the processing and memory systems can operate continuously. Typically, while one instruction is being executed, its successor is being decoded and a third instruction is being fetched from memory.

The ARM7TDMI-S processor also employs a unique architectural strategy known as Thumb, which makes it ideally suited to high-volume applications with memory restrictions, or applications where code density is an issue.

The key idea behind Thumb is that of a super-reduced instruction set. A piezoelectric sensor is used as accident detection sensor.

A piezoelectric transducer has very high DC output impedance and can be modeled as a proportional voltage source and filter network. The voltage V at the source is directly proportional to the applied force, pressure, or strain. The output signal is then related to this mechanical force as if it had passed through the equivalent circuit.

These receivers have a typical threshold of 1. HD44780U is used in the project. It can be configured to drive a dot-matrix liquid crystal display under the control of a 4- or 8-bit microprocessor. A single HD44780U can display up to one 8-character line or two 8-character lines.

The HD44780U character generator ROM is extended to generate 208 5X8 dot character fonts and 32 5X10 dot character fonts for a total of 240 different character fonts. It is a simple variable resistor preset with linear characteristics. This is used to adjust the contrast of the display. Reset control circuit is used to reset the microcontroller at any stage of work.

This section also comprises of auto power on reset. If the reset switch is pressed, the microcontroller restarts and the function will start from the beginning. This circuit is connected to 9th pin of microcontroller. A crystal is used to supply clock frequency to the microcontroller.

The clock frequency is 11. Despite the "oddball" value, these crystals are readily available and commonly used.
