Smart Data Acquisition System (SDAS)

Abstract

Our proposed project comprises of a system based on Data Acquisition that has an Over-speeding alert and location tracker module, an accident detection alert and locator, an obstacle avoidance system and a Black Box system for recording of the conversation during the course of commutation. Over-speeding alert module consists of a speedometer, a microcontroller and a GPS module that logs the location data of the point of over-speeding. The data is logged onto a memory unit that is installed on the module. The real-time speed of the vehicle can also be monitored digitally on a Liquid Crystal Display. The speedometer of the vehicle consists of an optical based speed sensor. The second module is the accident location tracker and alert system based on GPS and GSM module. The accident is detected using a 3-axis accelerometer. Exact GPS coordinates of the accident location are data logged onto memory card and an SMS based alert system sends the coordinates to contact numbers programmed into the microcontroller. The coordinates (longitude and latitude) are sent in the form of Google Maps links. The 3rd module equips with obstacle avoiding system that uses SONAR (Sound Navigation and Ranging). An ultrasonic sensor mounted onto the vehicle detects the obstacles in front of the vehicle and logs the respective data. The vehicle also senses the way to move on by looking towards either side. The 4th module is a “Vehicle Black Box” that logs the voice data of the conversation during the course of commutation. All the modules are mounted on a robot vehicle chassis. The vehicle is a rechargeable that has an option of variable speed.
