Abstract
The utility model discloses a device for monitoring the tire pressure of an automobile tire. The device consists of a wireless transmitter and a receiving display, wherein the wireless transmitter comprises a pressure sensor, a first singlechip and a signal transmitting unit; the pressure sensor is connected with the input end of the first singlechip, and the first singlechip is connected with the input end of the signal transmitting unit; the receiving display comprises a signal receiving unit, a second singlechip and a display; the output end of the signal receiving unit is connected with the input end of the second singlechip, and the output end of the second singlechip is connected with the input end of the display; and the signal transmitting unit communicates with the signal receiving unit through wireless signals. By adopting the device, the first singlechip converts an air pressure signal into a digital signal, and the second singlechip receives the digital air pressure signal and then transmits an alarm signal according to a set air pressure to ensure that the tire runs in a sound inflated state, so that the tire can be effectively prevented from being damaged due to underpressure or overpressure, and the transportation safety and quality are improved.
Description
Technical field
The utility model belongs to the automotive safety technical field, is specifically related to a kind of car tyre pressure monitoring device.
Background technology
For a long time, the damaged tyres that the tire pressure of automobile tire mal causes is that people pay close attention to the technical matters with headache always, when road conditions were bad, the damage damaged tyres that tyre underpressure aggravates tire had especially not only strengthened traffic cost, 2 years and traffic safety has been caused very large impact.When especially running at high speed, also can cause major traffic accidents when serious.At present mainly use two kinds of ways for addressing this problem according to investigations: 1, land indicating type, hang a string metal object on axletree, when tyre underpressure, axletree sinks, and metal object is landed generation sound; 2, contact wired alarming, during tyre underpressure, on axle, coupling link sinks to contacting with ground, produces signal and realizes reporting to the police to operator's compartment with wire link.Although these two kinds of ways all using, can't accurately be understood the tyre underpressure situation by them, can not in time take measures.
Summary of the invention
Defective or deficiency for above-mentioned prior art existence, the purpose of this utility model is, a kind of car tyre pressure monitoring device is provided, this device changes into digitized signal by the first micro controller system with air pressure signal, the second singlechip device sends alerting signal according to the air pressure of setting after receiving the digital pneumatic signal, tire is moved under the intact state of inflation, can effectively avoid having improved transportation safety and quality because of under-voltage tire and the too high situation of blowing out of tire pressure damaged.
In order to achieve the above object, the utility model adopts following technical solution:
A kind of car tyre pressure monitoring device, this device is comprised of wireless launcher and reception telltale two parts, wherein, described wireless launcher comprises the housing that is sleeved on cranked tire valve, pressure sensor, the first micro controller system and signal transmitter unit are installed in this housing, the mouth of described pressure sensor connects the input end of the first micro controller system, and the mouth of the first micro controller system connects the input end of signal transmitter unit;
Described reception telltale is arranged on automobile instrument panel, receive telltale and comprise signal receiving unit, second singlechip and telltale, wherein, the mouth of signal receiving unit connects the input end of second singlechip, and the mouth of second singlechip connects the input end of telltale;
Described signal transmitter unit and signal receiving unit communicate by wireless signal.
The utility model also comprises following other technologies feature:
Described wireless launcher adopts the wireless launcher of effective transmitting range 50m.
Described the first micro controller system and second singlechip all adopt 8 micro controller systems of CMOS.
Description of drawings
Fig. 1 is structural representation of the present utility model.Number in the figure implication: 1-pressure sensor; 2-the first micro controller system; 3-signal transmitter unit; The 4-signal receiving unit; The 5-second singlechip; The 6-telltale; The 7-wireless launcher; 8-receives telltale.
Below in conjunction with specific embodiments and the drawings, the utility model is further explained.
The specific embodiment
As shown in Figure 1, car tyre pressure monitoring device of the present utility model, formed by wireless launcher 7 and reception telltale 8 two parts, wherein, described wireless launcher 7 comprises the cylindrical shell that is sleeved on cranked tire valve, pressure sensor 1, the first micro controller system 2 and signal transmitter unit 3 are installed in this cylindrical shell, and the mouth of described pressure sensor 1 connects the input end of the first micro controller system 2, and the mouth of the first micro controller system 2 connects the input end of signal transmitter unit 3.Wireless launcher 7 is used for launching under-voltage signal, its effective transmitting range 50m.
Described reception telltale 8 is arranged on automobile instrument panel, receive telltale 8 and comprise signal receiving unit 4, second singlechip 5 and telltale 6, wherein, the input end of the mouth second singlechip 5 of signal receiving unit 4, the mouth of second singlechip 5 connects the input end of telltale 6.Receiving telltale 8 is used for the under-voltage signal that receives is shown and reports to the police.
Signal transmitter unit 3 communicates by wireless signal with signal receiving unit 4.
Described micro controller system adopts 8 micro controller systems of CMOS.
Each parts that use in the utility model all adopt the commercially available prod.
in actual applications, at first each tire be numbered and numbering be stored on the micro controller system 2 of wireless launcher 7, the shell of wireless launcher 7 is screwed on cranked tire valve, allow air pressure enter in the confined space of projector ground shell, pressure sensor 1 is housed in confined space, the air pressure of tire is added on pressure sensor 1 and obtains electric signal, and give the first micro controller system 2 with electric signal transmission, after processing, the first micro controller system 2 becomes digital signal, and this signal and the atmospheric pressure value of having set are compared, if signal air pressure is not transferred to signal transmitter unit 3 with tyre serial number and tire pressure signal in setting air pressure range, the signal transmitter unit is launched this signal.After the signal receiving unit 4 that receives telltale 8 is received the alerting signal that wireless launcher 7 sends, signal is passed to second singlechip 5, second singlechip 5 is converted into digital signal with electric signal and is presented at telltale 6, display of tyre numbering and acousto-optic is under-voltage or the overvoltage alarm on this moment telltale 6.Like this, which pressure of tire chaufeur just just can not know accurately, in time takes measures immediately to guarantee the good technique situation of vehicle.
The utility model is not limited to above-mentioned specific embodiments; those of ordinary skill in the art is in the situation that under the enlightenment of this specification sheets and do not break away from the scope that the utility model claim is protected; can also make a variety of forms, but all belong to the row of protection of the present utility model.
