Design of Embedded Based Automobile Safety Prealarm System

Now a days fatal traffic accidents occur due to tire burst, which threats the safety of drivers and automobiles. A new kind design scheme of sensing system is proposed for car safety. My design comes up with predesigned safety systems embedded with in the automobiles. Embedded module is implemented through Hardware components and software design for measuring the tire temperature and pressure. The whole system is host module located on the dashboard and another four wireless sensor microextensions located in four tires. The four wireless sensor microextensions located in tyres continously monitors the temperature and pressure of tyres in real time and transmits to host module through wireless module. The transmitted signals are received, decoded, and processed by the receiver to trigger the warning system through an alarm, lamp, audible alarm, voice, or pressure display. The monitoring host implements zigbee for receiving data and decodes and processes the data through ARM7 and when the tire comes up with abnormal conditions such as excess temperature or the pressure is high or low, or leaking the host module gives out audible and video signals to the driver to avoid fatal traffic accidents. In addition two IR sensors are interfaced with ARM7 to detect any nearby nearby vehicles when travelling at high speed to avoid severe accidents vehicles when travelling at high speed to avoid serious accidents.
