Description
Technical field
The present invention relates to a kind of cantilevered vibration energy collector for Tire Pressure Monitor System transmitting terminal, belong to
Environmental energy gathers field.
Background technology
The function of Tire Pressure Monitor System is to monitor tire pressure in real time, and receiving terminal shows that transmitting terminal passes through wireless telecommunications side in turn
Tire pressure that formula is sent and tire temperature data；Can carry out tire leak gas slowly the too low warning of tire pressure, the too high warning of overload of vehicle tire pressure,
The work such as the warning of tire aging abnormal tyre pressure, the too high warning of tire temperature, cell host low capacity prompt, and aobvious when stopping
When display screen is automatically switched off, battery is powered, main frame also can set according to vehicle and tire location automatically into parking battery saving mode
Fixed corresponding reference pressure value.The benefit installing Tire Pressure Monitor System has: detection tire pressure, pre-runflat；Save combustion
Oil, automobile reduces discharge；Reducing abrasion, tyre life is longer；Guarantee handling；Avoid the improper mill of vehicle part
Damage.
The effect of Tire Pressure Monitor System is to carry out tire pressure, temperature, deformation etc. in real time in vehicle traveling process
Automatically monitoring, and to having a flat tire and low pressure is reported to the police, to guarantee traffic safety.Its operation principle is: tire
Installing a sensor on valve inside, sensor includes the bridge type electron gas pressure induction installation of induction air pressure, and it is by gas
Pressure signal is converted to the signal of telecommunication, is emitted by signal by wireless launcher.Some tire checking sensors also comprise
Have measurement temperature, strain, by isoparametric for speed function, provide more safety information for running car.This sensor leads to
Cross and be transmitted wirelessly to receiving terminal, show various data variation over the display or with forms such as buzzings, remind motorist.
And report to the police when having a flat tire and pressure varies more than security restriction, with guarantee driving safety.
Just because of tire pressure detection has many benefits, vehicle accident occurrence probability can be reduced, protect personal safety as well as the property safety, institute
To have broad mass market.Owing to tire is a relatively independent space, tire pressure monitoring system cannot be supplied by wired mode
Electricity, general employing chemical cell is as power supply, but chemical cell exists volume greatly, the deficiency that service life is short, and waste and old
Battery disposal is improper also can cause serious environmental pollution, and energy acquisition becomes numerous scholar's research hot topic neck the most in recent years
Territory.Vibrational energy acquisition system research is the vibrational energy in the equipment utilization surrounding the most inconvenient for changing battery
Amount realizes energy-autarchic.
Tire Pressure Monitor System is divided into direct-type and two kinds of implementations of indirect type.Indirect type is by automobile ABS system
The wheel speed sensors of system compares the rotating speed difference between wheel, to reach to monitor the purpose of tire pressure.But the shortcoming of this mode
It is intended to running car one segment distance just can work, and can not plural tire deficency simultaneously be detected simultaneously
Etc..Direct-type is to be mounted directly sensor on tire, and sensor transmits the information such as tire pressure to receptor in car, reception
Device is shown.Advantage is that information is complete, highly sensitive, and therefore direct-type will be the Developing mainstream of following tire pressure monitoring system
And trend.The shortcoming of direct-type is that at present sensor battery the most on the market is all integrated design, and battery does not once have electricity, just
Will change together with sensor, later maintenance cost is the highest.The power supply of the sensor therefore solving tire pressure monitoring system is asked
Topic becomes one of key technology of restriction tire pressure monitoring system development.Direct-type divides again external and built-in two kinds of structures,
Built-in need to be arranged in tire, more difficulty is installed.External is arranged on valve inside, easy accessibility.
