1 Introduction
With the high speed of work booming rise, Traffic is developed, Vehicle speed increasing, traffic hazards prevention problems imminent, if because of the tire air-leaks and explosion etc cause traffic accident, many are by tyres work to high temperature or unreasonable tire pressure cause. Research car tires tire pressure monitoring system of modern automobile driving, when the economy, safety and manipulation stability is particularly important practical significance.
Hardware constitution and software design method of the universal TPMS are introduced based on PIC MCU. The Design projects of the remote monitoring module based on infineon SPI2 sensor, Microchip rfPIC12F675F with ASK/FSK transmitter and the central receiver module based on Microchip PIC16F877A are described, and hardware circuitry and related programs flowcharts, communication protocols and algorithms are given1The system can measure the tire's interior temperature, instantaneous pressure, voltage and acceleration at anytime, indicate the blooey tires and alarm the driver to avoid the
danger. It’s of great importance for the popularization and optimization of the TPMS in our country.
As authoritative research indicates, the key to Prevent a tire blow-out is maintaining standard tire Pressure and detecting tire fault beforehand. Thus, tire Pressure monitoring es meaningful and important.
TPMS ( Tire Pressure Monitoring System ), Mainly used in automobile driving real-time monitoring of tyre pressure automatically. Currently developed countries of the tire pressure early-warning system mainly divided into two types: one is JiaJieShi, it through car ABS (anti holding brake system) of the wheel sensor and tyre mechanical model, indirectly calculated for tyre pressure, in order to achieve the pur
