Through the improvement, the tyre monitoring display can display pressures and temperatures of four automobile tyres, and the electric quantity of the independent power supply of the tyre monitoring display; when the tyre pressure deviates from the set value, the tyre temperature is too high; and when the change of the tyre pressure is too fast or the electric quantity of the independent power supply is lower than the set value, the tyre monitoring display can sent out a prompt or alarm to call the driver's attention so as to reduce the occurrence of the accidents.
Description
Technical field
The present invention relates to a kind of tire monitor scope, specifically, relate to the tire monitor scope that is used for tire pressure, temperature, supplying cell electric weight supervisory system.
Background technology
Concerning general automobile, the tire pressure size has very big influence to the wear on tyres situation.The consumption of fuel that also can increase vehicle bigger than normal or less than normal of automotive tire pressure, lasting insufficient pressure can make the lost of life of tire reach 50%.In addition, the deviation of tire pressure also can cause rupture of tire and vehicle to catch fire, and therefore, many chaufeurs all will spend a large amount of time periodic inspection tire pressures.
In view of the foregoing, prior art provides a kind of tire pressure monitoring telltale.This tire pressure monitoring telltale comprises a wireless receiver, in order to receive pressure signal; One data handler is in order to pressure data and the processing that receives wireless receiver; One telltale, in order to receiving the pressure data of data handler, and the pressure data of four tires of display automobile in turn.The power supply of this tire pressure monitoring telltale uses automobile power source.
Because the power supply of tire pressure monitoring telltale uses automobile power source, this just makes that the combination degree of telltale and automobile is comparatively close.As everyone knows, the automobile of newly buying, the parts of car or components and parts generally do not allow the buyer to open privately or dismantle, otherwise do not bear the repairing responsibility for the parts of car or the damage of components and parts.So, in case the tire pressure monitoring telltale breaks down, Fault Diagnosis and reparation all can meet with obstruction.And the pressure data of four tires of automobile shows in turn, also not enough intuitive and convenient.
Summary of the invention
The objective of the invention is to, a kind of tire monitor scope is provided, use independent current source, and the pressure data of four tires of display automobile and tyre temperature, acceleration information simultaneously; When underinflation of tire or temperature when too high, can give a warning, remind chaufeur to note, thereby reduced the generation of accident.
In order to achieve the above object, technical scheme of the present invention is as follows:
A kind of tire monitor scope comprises: a wireless receiver, in order to receive the tire pressure data signal; One is connected to the data handler of described wireless receiver, which is provided with the pressure comparison module; One read-out shows the pressure data that described data handler provides; One annunciator that links to each other with described data handler; When tire pressure departed from the standard value of setting, the pressure comparison module triggered described alarm equipment alarm; Be characterized in that described tire monitor scope also comprises an independent power supply, it provides electric weight to described wireless receiver and data handler.
Described read-out is the pressure data of four tires of display automobile simultaneously.
Described wireless receiver can receive the tyre temperature data-signal.
Described data handler is provided with temperature comparison module, and when tyre temperature during greater than the design temperature higher limit, this module triggers described alarm equipment alarm.
Tire monitor scope of the present invention also comprises an independent power supply voltage detection unit, and it sends to described data handler with detected voltage signal.
Described data handler is provided with the independent power supply voltage comparison module, and when voltage was lower than setting value, this module triggered the electrically-charged information of display alarm user on the described read-out.
Described data handler is provided with memory module, in order to the status data and the time data of record warning.
Described data handler is provided with tire pressure and changes comparison module, and when tire pressure changed above setting value, this module triggered described alarm equipment alarm and/or triggers read-out display alarm user's information.
Described independent power supply is the 5V rechargeable battery.
Described annunciator is a buzzer phone.
By above-mentioned improvement, the tire monitor scope is pressure, the temperature of tire and the electric weight of tire monitor scope independent power supply of four tires of display automobile simultaneously; When tire pressure departs from setting value, tyre temperature is too high, when tire pressure changes electric weight too fast or independent power supply and is lower than setting value, can send prompting or warning, reminds chaufeur to note, thereby has reduced the generation of accident.
