Description
Technical field
The present invention relates to vehicle electric field, particularly relate to a kind of TPMS system be arranged in motor tire.
Background technology
Tire is the important component part of automobile chassis, and as important supporting member and walking element, tire not only carries the all-mass of automobile, and also will advance to automobile provides propulsive force, plays the effect relaxing ground shock simultaneously.The economy of tire to the road-holding property of automobile, ride comfort, safety, traveling comfort and fuel oil all plays a part very crucial.
In order to ensure vehicle safety travel, now comparatively current method is on automobile, install tire pressure monitoring system (TPMS), the parameters such as the air pressure of Real-Time Monitoring tire, for the low tire pressure caused because of tire flat, and Yin Gaowen, high tire pressure and easily produce the situation of blowing out, with visual signal or also can comprise audible signal and carry out showing and reporting to the police.The safety of running car can be improved like this, and the tire accelerated wear test caused because air pressure is not enough and the energy consumption reducing vehicle can be reduced.
Existing TPMS sensor is installed and is adopted TPMS sensor integration tire tube valve then by the mode that tire tube valve and wheel hub are fixed, and such mounting means exists the following defect:
One, different automotive hubs requires different tire tube valves and adapts to, and such TPMS system sensor all needs independent exploitation for different tire tube valves, adds cost of development, and the component part of product too increases tire tube valve cost simultaneously;
Two, existing TPMS utilizes integrated tire tube valve as RF antenna, and the net mate of resistance difference to circuit high frequency of tire tube valve brings certain difficulty;
Three, integrated tire tube valve adds the weight of TPMS sensor, is unfavorable for little to volume, the lightweight future development of sensor;
Four, existing TPMS sensor integration tire tube valve is fixed on wheel hub as a part, and tire tube valve is exposed to outside tire, makes sensor often can be subject to the impact of some harsies environment such as water spray of ESD, rubble, High Temperature High Pressure;
Five, the fragile sensor of tire dismantling.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can adapt to various wheel, and antijamming capability is strong, is affected by the external environment little, dismantles non-damageable TPMS system.
For solving the problems of the technologies described above TPMS system of the present invention, comprising:
Tyre pressure sensor module, is arranged in motor tire, for detecting temperature, the pressure of tire, and sends the information of detection to tire pressure monitor scope;
Tire pressure monitor scope, is installed in operator's compartment, for receiving the information of tyre pressure sensor module, monitors and temperature, the pressure of display of tyre;
Described tyre pressure sensor module comprises:
Temperature sensor, is connected with MCU module, for detecting the temperature in tire;
Pressure sensor, is connected with MCU module, for detecting the pressure in tire;
Acceleration pick-up, is connected with MCU module, for detecting the acceleration/accel of tire;
MCU module (micro controller module), its mouth is connected with RF circuit, processes the data of temperature sensor, pressure sensor, acceleration pick-up collection, judges that whether the data gathered are normal;
RF circuit (radio-frequency circuit), is connected with radio-frequency transmissions antenna, the data after MCU module process is launched with wireless radio frequency mode by radio-frequency transmissions antenna.
Wherein, described radio-frequency transmissions satellite transmitted frequencies is 433.92MHZ ± 100KHZ.
The temperature sensor of TPMS system tyre pressure sensor module of the present invention, pressure sensor, acceleration pick-up, MCU module and RF circuit can integratedly be made in an IC chip.
TPMS system tyre pressure sensor module of the present invention has independent RF circuit, without the need to integrated tire tube valve as radio-frequency transmissions antenna; TPMS system of the present invention can adapt to various wheel, and antijamming capability is strong, is affected by the external environment little, dismantles not fragile.
