Design and Implementation of Embedded in-Vehicle System with Multitask Management Using RTOS

Abstract

several survey reports on vehicle accident say that, mostly accidents are happening due to Drunk and driving, driver’s drowsiness and, over speed. Unnecessary sudden parking of vehicles on highways at night time is another factor .If these mistakes are corrected accidents can be reduced to some extent. If accidents occurred, immediate first aid and treatment is necessary to save life. But if there is no neighbor the case may be severe. Keeping all these in mind a new system is proposed which can perform the necessary steps to prevent accident and incase if accident happened system will inform the owner and ambulance about this accident by tracking location using GPS and send text message using GSM. The designed system involves in two sections1. Monitoring 2.control. These two are two sequence of actions. In monitoring phase it detects alcohol consumption, steering wheel grip, engine Temperature measurement, accident detection and distance between front and corresponding vehicle .In controlling phase system responds automatically for the above abnormalities and controls the engine. system software is designed using “ RT kernel” and “Keil Micro vision 5” to be worked on the target board of LPC2148. This system makes vehicles as highly secured.
