Description

The TPMS projector prevents the caliberating device of data collision

Technical field

The utility model relates to the technology of a kind of tire temperature tire pressure monitoring system (TPMS) projector, particularly a kind of caliberating device that prevents data collision for the TPMS projector.

Background technology

At present, the TPMS product is defendd device as automobile active safety, the huge market demand.The standard that Chinese automobile research institute formulated TPMS in 2009, the solar obligation standard of automobile also under study for action.Every cover TPMS comprises a receptor and Duo Tai projector (for sake of convenience, below take 4 projectors as the example explanation), each projector has own unique identity label ID, every negative air pressure and temperature regime now detected in corresponding tire of projector, when abnormal, receptor sends warning, reminds chaufeur, the generation avoided traffic accident.

During use, successively 4 projectors are respectively installed on 4 tire wheel hubs of automobile, 4 projectors do not contact as Fig. 1 fully.Here have a hidden danger: the time gap that these 4 projectors send wireless datas is random, likely exist two or branched projector send wireless data simultaneously, data bump, and cause data to send unsuccessfully.For preventing the collision of TPMS emitter data, can adopt in theory intercommunication system as Fig. 2, by receptor, draw a plurality of LF transmitters, by being arranged on the LF projector on the motor tire fender, control the transmission time interval of TPMS projector, avoid collision.This mode cost rises, and difficulty is installed, and domestic TPMS enterprise seldom adopts at present.

Current domestic TPMS enterprise adopts the data transmission cycle that changes every projector mostly, with the time gap of every twice transmission data, is all that random data prevents that data from sending collision always.This technology is owing to not increasing hardware cost and cost of installation, by domestic large data TPMS enterprise, adopted, but this technology is perfect at first not, can not avoid data collision/collision problem fully; Secondly there is no rule for receptor receives the time that shows data, the user experiences poor.The novel utility model patent (CN102285306A) that has been applied of this technical application, the utility model name is called the TPMS projector and prevents the data collision method.

Chinese patent application CN101425222A discloses a kind of data emitting method, and step comprises: projector according to different the first launch time, is sequentially launched data to this receptor respectively in an emission cycle; Then by these different first launch times respectively with different accumulated value addition, to become respectively different the second launch time; Then these different accumulated value multiples were added up those different first launch times; Last those projectors are according to those different second launch times, and in next emission cycle, next data of emission are to this receptor.This utility model, by the method for different the first launch time, has been improved the data collision problem of a plurality of projectors, but the Transmission Time Interval difference of projector, and this technology can not be avoided data collision/collision problem fully equally; And the time that the receptor reception refreshes the demonstration data does not have rule yet, and the user experiences poor.This is problem to be solved in the utility model just.

The utility model content

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of TPMS projector to prevent the caliberating device of data collision.

For achieving the above object, the utility model adopts following technical proposals:

A kind of TPMS projector prevents the caliberating device of data collision, comprises housing, is provided with treater in housing, and surface of shell is provided with the read-out, the time gap that are connected with treater and button is set, starts to demarcate button, projector excitation line interface and power interface.

Described read-out is LCD display.

A kind of TPMS of utilization projector prevents that the caliberating device of data collision from preventing the calibration method of data collision, after every cover TPMS transmitter circuit board has been produced, before embedding, use described caliberating device the TPMS projector to be carried out to the triggering of constant duration, with benchmark launch time that this cover TPMS projector is set (following take 4 projectors describe as example), concrete steps are as follows

1) excite some projectors connection lead to access successively the projector excitation line interface of caliberating device;

2) to caliberating device, power on, by time gap, the level triggers time gap that button and LCD display arrange projector excitation line interface being set is T/4, the wireless transmission data cycle that T is projector;

3) circuit card of the TPMS projector before embedding is fixed by fixture, thimble and projector by fixture excite connection lead to connect to be connected;

4) press starting on caliberating device and demarcate button;

5) some projector excitation line can be successively become high level according to the time gap of T1=T2=T3=T/4 by low level;

6) when the treater of some projectors detects positive rise, with regard to being set, the timing of oneself launching wireless data starts, the time reference of projector emission wireless data timing just differs T/4 successively like this, data collision occurs never again, the read-out of receptor also can receive successively and show, the user experiences;

7) repeat above step 3), 4), 5) can be demarcated or again be demarcated different projectors.

The beneficial effects of the utility model are, the utility model is on the basis that does not increase TPMS projector hardware cost, by caliberating device arrange many projectors launch time benchmark and regular time interval, thoroughly solved the data collision/collision problem of projector, and receptor receives the time gap that refreshes the demonstration data and fixes, there is user preferably to experience.
