Car Black Box using 8051

Hello everybody !
  My name is Rutvij Pathak .I am a aspiring engineer from India . I recently completed my pre - engineering diploma . For our final year in diploma we had to create a project . Me and my friends chose to do a project named " Multipoint data acquisition system for vehicles . Now its all a fancy name but in essence it is a 'Black Box ' designed for car or vehicles in general .


 
ABSTRACT

Multipoint wireless data acquisition system for vehicles is system developed for vehicles, which notifies a predetermined user in an event of collision of the car. Predetermined user is notified through GSM system via SMS.SMS sent to the user contains various vital statistics regarding the temperature of the car and its GPS location at the present time. LCD display is used to display various sensor values.

The vehicles are constantly monitored with help of various sensors. Sensors used are accelerometer, Temperature sensor and Flex sensor. Accelerometer is used to determine the orientation of the car at a given time. Temperature sensor is used to record the temperature of the vehicle i.e. cabin temperature, engine bay temperature etc. Flex sensor is used to determine if an actual collision has happened i.e. if the vehicle has crashed into something.

All these above sensors are on the same priority level i.e. if any of the above sensors goes above a certain threshold; the microcontroller sends a message via GSM transmitter.

LCD display (16X2 alphanumeric displays) is used to display various sensor values.
