Description
Technical field
This utility model relates to technical field of automotive electronics, particularly relates to a kind of instrument in segment encode screen display tire pressure
Table system.
Background technology
In automotive field, tire pressure monitoring system generally uses TFT screen and liquid crystal display screen to show, often brings automobile
Cost increases, and the most only just possesses in high-end vehicle.But along with " performance requirement of passenger vehicle tyre pressure monitoring system and examination
Proved recipe method " enforcement, it is desirable to low side vehicle tire pressure monitoring to be possessed function, but so far, also not having can be preferable
Control cost, make it the tire pressure monitoring system being equipped with in low end vehicle.Additionally, conventional truck can only monitor the tire pressure of wheel
Value, but in addition to the display of tire pressure value, the alarm lamp of correspondence can not be lighted when tire pressure value is low, the most intuitively.
Utility model content
For solving above-mentioned technical problem, this utility model provides a kind of with low cost, generally can implement in low side vehicle
The instrument system in segment encode screen display tire pressure.
The technical solution of the utility model is: a kind of instrument system in segment encode screen display tire pressure, including tire pressure
Monitor, tyre pressure sensor, instrument chip, many segment decoders and the tire pressure corresponding with tire and tyre pressure sensor number are alert
Showing that lamp, described tyre pressure sensor are distributed at each tire of vehicle, its outfan electrically connects with tire pressure detector, described tire pressure
Monitor outfan electrically connects with instrument chip, and described instrument chip controls signal output part electrically connects with many segment decoders, institute
State many segment decoders and include multiple and tire pressure warning lamp low and high level signal output part one to one, multiple described low and high levels
Signal output part electrically connects with tire pressure warning lamp, and described tire pressure warning lamp is fixed on the short in size screen inner surface of instrument.
Further, described short in size screen surfaces is provided with vehicle and indicates, and shown tire pressure warning lamp is arranged at each of vehicle sign
Individual tire corresponding position.
Further, also including the multistage charactron for showing tire pressure value, described many segment decoders have many with described
The low and high level signal output part of each charactron monomer electrical connection of segment numeral pipe.
Further, the display screen of affiliated instrument is short in size screen.
The beneficial effects of the utility model are: use short in size screen with low cost to replace traditional TFT screen and liquid crystal display screen,
Vehicle mark is set on short in size screen, and the tire pressure warning lamp being connected with many segment decoders is set in beautiful relevant position.Work as vehicle
Certain tire occurs when tire pressure failure or air pressure are too low, and many segment decoders can export high electricity according to the control signal of instrument chip
Put down to specific pin, thus light corresponding tire pressure warning lamp, play the effect of early warning.Additionally, the concrete atmospheric pressure value of tire is also
Multistage charactron can be lighted by many segment decoders and show.
Accompanying drawing explanation
Fig. 1 is this utility model circuit connection diagram；
Fig. 2 is this utility model segment encode screen interface schematic diagram；
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Specific embodiment described herein is only in order to explain that this practicality is new
Type, is not used to limit this utility model.Additionally, involved by each embodiment of this utility model disclosed below
Just can be mutually combined as long as technical characteristic does not constitutes conflict each other.
As it is shown in figure 1, the present invention include tire pressure monitor, tyre pressure sensor, instrument chip, many segment decoders and with wheel
Tire and the corresponding tire pressure warning lamp of tyre pressure sensor number.Tyre pressure sensor includes left front tyre pressure sensor T1, right front tire pressure
Tyre pressure sensor T4 behind sensor T2, left back tyre pressure sensor T3 and the right side, four tyre pressure sensors are distributed in the four of vehicle respectively
At individual tire.Tyre pressure sensor outfan electrically connects with tire pressure detector, and tire pressure monitor outfan electrically connects with instrument chip,
Instrument chip controls signal output part electrically connects with many segment decoders, and many segment decoders include multiple one a pair with tire pressure warning lamp
The low and high level signal output part answered, and export with the charactron monomer low and high level signal one to one of multistage charactron
End.
Indicating as in figure 2 it is shown, short in size screen surfaces is provided with vehicle, tire pressure warning lamp is arranged at short in size screen inner surface, vehicle mark
Each tire corresponding position shown.
Tire pressure warning lamp, in the case of the low pressure alarming/NO ID/ system failure/battery electric quantity is low, lights fault tire
Position；When multiple tires simultaneously air pressure is low, by the atmospheric pressure value of minimum that tire of multistage numeral method wherein pressure,
Light the position of the low tire of all air pressure simultaneously.When sensor fault being detected or battery electric quantity is low, show tire pressure value
Display ". ", lights corresponding fault tire location simultaneously.When NO ID being detected, tire pressure show value is empty, same to time point
Bright corresponding fault tire location.
The above, detailed description of the invention the most of the present utility model, it is noted that any be familiar with those skilled in the art
Member in the technical scope disclosed by this utility model, the change that can readily occur in or replacement, all should contain at this utility model
Protection domain within.
