The Design of Vehicle Tire Pressure Monitoring System Based on Bluetooth

摘要

A car backfiring is an important cause of traffic accidents. The vehicle tire pressure monitoring system (TPMS) is an automobile accident prevention system. This paper designs a tire pressure monitoring system of motor vehicles based on Bluetooth using the detection and sensing technology, single-chip microcomputer's control technology and Bluetooth technology synthetically. The system includes two parts of lower computer and upper computer (mobile phone) and the lower computer can monitor in real time and process the tire pressure parameters. In addition, the lower computer will send the tire pressure data processed by it to the mobile phone through Bluetooth, and then mobile phone checks the data and displays the detecting results to inform the driver of the state of vehicle tire pressure. This system realizes some functions including the detection of tire pressure in real time, display of tire pressure data and warning function through mobile application.
