Automatic vehicle accident detection and messaging system using gsm and gps modem
- 1. AUTOMATIC VEHICLE ACCIDENT DETECTION AND MESSAGING SYSTEM USING GSM AND GPS MODEM
- 2. Why this project? Importance of GPS Importance of GSM 89c52 MAX 232 Block diagram Power supply Hardware and software's used Advantages Scope of advancement Applications Conclusions References
- 3. Security in travel is primary concern for every one. Accident spot can be detected . SMS can be received from the spot .
- 4. GSM (Global System for Mobile communications). GSM is a digital cellular communications system. It is used for transmitting mobile voice and data services.
- 5. International roaming capability. Encryption capability for information security and privacy Better security against fraud (through terminal validation and user authentication)
- 6. IMPORTANCE OF GPS GPS (Global Positioning System) GPS always transmits the data GPS Receiver gets the location information from satellites.
- 7. 89C52 MICROCONTROLLER 8052 controller is Mask Programmable. Derivative of 8052 microcontroller is the 89C52 microcontroller. It has 4 ports. It is an 8 bit device for I/O.
- 8. 4K Bytes of ROM Space. 256Bytes of RAM space. It also has Timer, Serial Port interface and Interrupt controlling.
- 9. MAX 232 is an dual driver/receiver It is used to convert the TTL/CMOS logic levels to RS232 logic levels during serial communication of microcontrollers with PC. RS-232 TTL Logic -25V to-3V +2V to+5V High +3V to+25V 0V to +0.8V Low
- 10. We require: TTL logic level (0-5V) and RS232 standards (-25 V to + 25V). Hence difficult to establish a direct link. We go for an intermediate link i.e. MAX232. MAX232 provides best noise rejection and very reliable against discharges and short circuit.

- 13. This project uses : regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer. KEIL IDE VB code
- 14. Sophisticated security Monitors all hazards and threats Alert message to mobile phone for remote information Mobile number can be changed at any time
- 15. If anybody steals our car we can easily find our car around the globe. By keeping vehicle positioning vehicle on the vehicle . We can use our kit for detection of bomb by connecting to the bomb detector.
- 16. Automotives and transport vehicles. Security, remote monitoring, transportation and logistics. This system also can be interfaced with vehicle airbag system.
- 17. The positioning is done in the form of latitude and longitude along with the exact location of the place, by making use of Google maps. .
