A unified approach to design a low power tire pressure monitoring system and utilization of SOC

Abstract

Major cause for serious traffic accidents may be bursting of tires. Therefore the number of traffic accidents is increased along with the fast growth in number of vehicles, which creates damages to automobiles and also human body. For the drivers, bursting of tire is main concern as it is very complicated to avoid. This research demonstrates that tire burst is mostly caused by nonstandard tire pressure. Therefore traffic accidents are avoided if the pressure of tire is frequently monitored during driving. Tire pressure Monitoring System (TPMS) is a newer method to estimate the tire pressure in real time. This method alerts the driver by a horning alarm while the pressure goes to low or higher. The tire pressure monitoring system is presented by employing the system on chip (SoC) mixed signals with the help of Bluetooth transmission and in advantage of low power consumption design. This method can monitor the variations in temperature and pressure of the tire of vehicle, the TPMS system is included. The driver s safety can be improved by automatically newlinefinding the tire pressure and tire temperature and after that alerting signal can be sent to driver to obtain a measure, which avoids from accident. This presented method of tire pressure monitoring system utilizing SoC enhances the indication time speed to the driver by employing mixed signals. The tire inflation is avoided by preventing from high temperature and high pressure. Limitation of temperature and pressure in the previous system is also elongated (i.e) temperature from -40O C to 125O C and pressure from 0 to 750 Kpa. Sensors, wireless communication (Bluetooth dongle) and SoC unit is used to design the low power TPMS. Quantitative results are taken and the analogy between temperature and pressure is also verified. The tested results proved by need of the practical system. Signal conditioning voltage and SoC newlineunit is the trace for low power design TPMS. newline newline
