Description
Technical field
The present invention relates to the field of different brands tyre pressure sensor, espespecially the instrument of the programming of wireless blue tooth communications protocol imprinting and the method for operation of wireless blue tooth write are carried out to the tyre pressure sensor of different brands simultaneously.
Background technology
Along with country is to the attention of traffic safety, the paces in North America and European car market progressively can be followed in Continental Area, on the four-wheel car of listing, progressively radio tire pressure monitoring system TPMS assembles in Compulsory Feature depot, but because of automobile year of manufacture, car system, location is different, the tyre pressure sensor of different brands is mutually incompatible with the communications protocol of genuine, tyre pressure sensor genuine must being selected corresponding when causing the vehicle installing tyre pressure sensor to change tyre pressure sensor on rear dress market.
The incompatibility of the tire pressure monitoring system agreement of different brands causes the service provider of after market, terminal client pays through the nose for this reason, no matter be that sensor midway is damaged, the unconventional size repacking of tire or sensor battery level exhaust (tyre pressure sensor battery electricity usually can not more than the service life of 5 years), service provider and client need to prepare special tyre pressure sensor for specific vehicle specially, consuming time, effort, waste resource, this kind of mode must to improvement.
Summary of the invention
This patent technical matters to be solved is: provide a kind of universal pressure meter, on existing market, and can not the uncurrent problem of tire gauge between brand; Realize between different brands with a back tyre meter.
For completing foregoing invention object, the present invention realizes: a kind of universal bluetooth programming tyre pressure sensor; It comprises tested tyre pressure sensor, instrument reader, information writing device and blank sensor, it is characterized in that: described instrument reader comprises low frequency signal binary pair, low frequency signal receptor, message memory and microprocessor; Described low frequency signal binary pair launches low frequency signal to tested tyre pressure sensor, and the information be reflected back by tested tyre pressure sensor is received by low frequency signal receptor, the transmission of Microprocessor S3C44B0X low frequency signal binary pair, low frequency signal receptor and reception; And information is judged; Call the corresponding fetch program, be deposited into message memory by after corresponding fetch program reading information; Described information writing device is made up of bluetooth module, and described bluetooth module adopts signal to be connected with between memory device and blank remote place sensor; Described blank sensor is furnished with fixing telltale, is connected with adopting data line between telltale.
This patent has done very large improvement to conventional art, in the past, due to standard disunity, different manufacturers when making respective tire gauge, employing be different sensors, different standard agreements, cause use of not uniting each other, so, mutually can not read data between them, more laughable, due to edition upgrading cause same producer all have no idea read.These reasons just, now once need to change, just quite complicated, need to carry out customized.Basis is special must adopt instrument reader, detection signal is sent to sensor, make sensor backspace signal, by the signal returned, judge sensor essential information, but after from memory device, call corresponding application program thus data in read sensor, by bluetooth module, the information understood is re-write new blank sensor after this data reading, is shown by the telltale of blank sensor standard configuration.
The Second Problem that this patent solves is to provide a kind of method that can read disposable type tyre pressure sensor, specifically comprises the following steps:
(1) low frequency signal binary pair peritropous sensor under the manipulation of microprocessor sends low frequency signal; The sensor of periphery receives backspace signal after signal, is received under control of the microprocessor by low frequency signal receptor; And unloading is to temporary storage cell;
(2) microprocessor reads information from temporary storage cell, and judges it, analyzes combination; Call the corresponding fetch program, read information; And by information stored in memory device;
(3) the corresponding blank sensor of information correspondence write in memory device is read by the bluetooth module of information reader;
The corresponding telltale of blank sensor shows corresponding information data.
The described fetch program is the original recognizer provided by tested sensor genuine.
Described microprocessor reading information from temporary storage cell is genuine communications protocol and sensor genuine identification code.Again energizing signal is transmitted to blank sensor by low frequency signal binary pair after the blank sensor of write; Repeat second step, and the information deposited into by secondary and raw information are compared; Comformed information all writes.
The low frequency of this patent sensor returns the information of penetrating and judges the version program that sensor needs, then call corresponding program to understand, adopt bluetooth module to compile after understanding, be sent to blank sensor, this blank sensor adopts the standard configuration read mode being again.After adopting said method, for repairman, as long as need a kind of reader just can read the tire information of all models.Moreover, in addition, this blank sensor can also receive the tire information of several vehicles simultaneously, is undertaken reconfiguring arrangement by information by reader, different tire informations is delivered to position corresponding on telltale.
Adopt said method can carry out the wireless blue tooth transmission of genuine heading code and communications protocol to 2000 blank tyre pressure sensors simultaneously, and simple to operate; Certainly write at the same time, also require that reading instrument can read 2000 tested sensors simultaneously.
After obtaining information after adopting said method to read multiple tested sensor, bluetooth module mentions corresponding information, carries out permutation and combination, arrange, and subpackage is to same blank sensor transmission; Different information measured is shown in order by telltale.
