Specific embodiment makes further instructions the installation of the system of the utility model below：
By one 6 wheel bus for, before left and right single-wheel be named as 1, No. 2 tire, behind left and right for two-wheel name
For 3,4 and 5, No. 6 tires, ID modules built in preprepared tire and temperature and pressure sensing are loaded onto inside each tire
Device module, ID modules are combined together by way of physical connection built in temperature/pressure sensor module and tire.
Tire ID fixation and recognition module is loaded onto in the position of the front mudguard of each tire, as shown in Figure 7：In vehicle just
To installing a diameter of 142*142mm square racks 2 on the mud guard 3 in 4 centre position of tire, by tire identification module 1 four
Angle is screwed on stent 2（Tire identification module cannot be directly mounted on mud guard）, it is located at tire identification module 1
Tire tread middle, module front are less than 30cm with tyre surface air distance.It is opened on mud guard 3 behind 2 middle of mounting bracket
Then interface of the vehicle body power supply directly with tire ID identification module 1 is connected by the circular hole of a a diameter of 20mm.Power supply mould
Block is the voltage the accumulator of vehicle itself（The direct current supply of 20-24V）It is available and not to be converted into tire ID identification module
Influence the normal voltage of device function, it is desirable that power module will also have certain water-proof function, and do in the inside of power supply certain
Filtering process, to improve the quality of out-put supply.
Radio receiving terminal is mounted on the bottom of vehicle body, is connected with cable with the display of position of driver, and to this
Monitor power supply；This completes the installations and power supply of all parts of tire positioning identification system.
Radio receiving terminal, function are that the 433.92MHZ wireless datas that will be received are converted to electric signal and are transmitted to CPU（It is aobvious
Show processing module）Processing is exactly a hardware decoding, wireless data is converted to TTL signal.
The workflow of the tire identity positioning identification system based on tire temperature pressure monitoring system of the utility model is as follows：
Tire temperature tire pressure monitoring system starts powered operation, tire fixation and recognition module while vehicle body general supply is opened
It can start powered operation together（On condition that tire ID number on the respective wheel position of foetus is not known）, the prison of tire temperature tire pressure monitoring system at this time
Survey is can not work normally because not knowing the ID number of the sensor of the inside tires on corresponding position.
（Assuming that do not know the ID modules of inside tires are mounted in which position of inside tires, because in tyre rotation yet
When we do not know when inside tires ID modules and external tire ID identification module are at a distance of within 30CM yet）
The tire identification module each installed on the wheel position of foetus at this time can continuously transmit the carrier signal of certain frequency by low frequency module, directly
The microcontroller of tire ID identification module on to the respective wheel position of foetus（MCU）MCU can be deposited after detecting the signal that ID modules issue
Then storage data at this time allow low frequency module resets by controlling signal pins, then repeatedly above step, next time such as
Fruit receives identical ID data and then stores data, and the ID number for recording this inside tires sensor is the last data received,
And the power control pin for passing through MCU goes to close the work of low frequency module；If the data received for the second time are different with first time
The data received for the first time are then abandoned, then reset low frequency module again until the identical just storage of the data received twice to MCU
In internal storage region, then go to close work (the low frequency module at this time of low frequency module by the power control pin of MCU again
It is least in power-consuming).（The operation principle of six tires is the same）.
Identified and stored in MCU at this time it is each wheel the position of foetus on corresponding tire ID number, using MCU encapsulation and
It handles, plus the wheel position of foetus corresponding to tire identification module in data after treatment（Such as：01 the near front wheel, 02 off-front wheel, 03
Left back revolver, 04 left back right wheel, revolver behind 05 right side, 06 right rear right wheel）And the regular coding of every suit product, by high frequency mould
The frequency of block 433.92MHZ sends the radio receiving terminal of tire temperature tire pressure monitoring system to（The mechanism of transmission is：Every time again on
After electricity, after detecting correct ID number, send 5 packets every 500ms and send 10 packets altogether, send 4 times altogether, the 2-3S times are sent out
Complete, being in dead angle with protected tyre influences the transmission of data.）, the radio receiving terminal of tire temperature tire pressure monitoring system is again in data
The Display processing module of tire temperature tire pressure monitoring system is transmitted to, Display processing module carries out upon receipt of the data and to the data
It understands and is compared with the ID number on corresponding tire position in original Display processing module, abandoned new data if the same, such as
Fruit is different, and old ID number is substituted for new ID number, thereby realizes the change of real time tire ID number so as to fulfill tire
Identification and positioning.
Above process realizes the Auto-matching of tire ID number in the case of no manual intervention, that is, completes complete
The whole process of automatic tire fixation and recognition.After ID number matching correctly on each wheel position of foetus, tire temperature tire pressure monitoring system
Radio receiving terminal can normally receive the monitoring data that sensor sends over, be then transferred at Display processing module
Desired data are shown after reason on the screen, and perform the warning function in the case of tire temperature abnormal tyre pressure.
So far automatic positioning function of the Full-automatic tire positioning identification system to tire can be realized, to assist tire temperature tire
Pressure monitoring system it is more intelligent.
The above descriptions are merely preferred embodiments of the present invention, is not to make any other to the utility model
The limitation of form, and any modification made according to the technical essence of the utility model or equivalent variations, it is new to still fall within this practicality
Type range claimed.
