2、fic 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 modem automobile driving, when the economy, safet

3、y 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

4、 transmitter and the central receiver module based on Microchip PIC16F877A are described, and hardware circuitry and related programs flowcharts, communication protocols and algorithms are given 1 The system can measure the tires interior temperature, instantaneous pressure, voltage and acceleration

5、 at anytime, indicate the blooey tires and alarm the driver to avoid the danger. Its 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

6、 fault beforehand. Thus, tire Pressure monitoring becomes 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 i

7、nto two types: one is JiaJieShi, it through car ABS （anti holding brake system） of the wheel sensor and tyre mechanical model, indirectly calculated fbr tyre pressure, in order to achieve the purpose; monitor tyre pressure Another kind is direct type, it USES installed in each of the tires with lith

8、ium ion battery fbr power supply pressure sensor to direct measurement of tyre pressure, and through wireless modulation launch to install in search of monitor, and monitor at any time display various tyre pressure, drivers can intuitivey understanding each tire pressure condition, when the tyre pre

9、ssure is too low or have leakage, the system will automatically alarm, ensure safety.TPMS as a new type automobile active safety device has been developing rapidly in recent years worldwide. Since it could monitor tire pressure and temperature in real time and alert the driver in time, most traffic

10、accidents caused by flat tire could be avoided to ensure safe driving. The development of tire pressure monitoring systems is reviewed including wheel speed based TPMS, pressure-sensor based TPMS and the coming generation so called non-battery passive TPMS. The components and working mechanism of ti

11、re pressure monitoring system are introduced and their merits and defects analyzed and compared with the emphasis on three dominant direct TPMS systems, which are significant in its research and development. The prospect of future development trend is looked ahead. The non-battery TPMS is expected t

12、o replace the current one and become the dominant. Wireless signal transmission stability reliability insufficiency, the battery life problem, sensor life and durability problem, is the present T PMS products in the common problem. This system in addition to the sensor, all use Microchip company tra

13、nsceiver chip and micro control processor, low energy consumption, good compatibility and high reliability.And utilize FSK modulator mode, one-way communication mode, improving the system of signal transmission of anti-interference ability. Combined with the system USES the SP12 sensor and monitorin

14、g module microprocessor rfPIC12F675F characteristics, adopt LF low-frequency sensei technology, time-sharing send and receive different monitoring module rf signals, thus solving signal collision interference problems, and further energy saving system.2 System RequirementsCause a flat tire and blowo

15、ut reasons are as follows: tyre temperature is exorbitant, the tyre pressure too big, tyres used fbr a long time, tire overload, automobile driving too fast.For that car to be in a safe driving condition, drivers must in driving process real-time understand tyre overpressure, voltage, temperature, e

16、tc. Work of the state, the system has the following functions: real-time monitor tire pressure, temperature conditions, when a tire over-voltage, overheating, automatic sound and light alarm, when a tyre in under voltage condition, corresponding the advantages indicator emit light.3 Hardware DesignThe system was divided into two Parts functionally: tire Pressure measuring block and central monitoring block.The hardware composit
