Launch outward the chip of signal.For example, radio frequency transmission chip 33 can use 7035 type of SMI or sp370 cake core.
In the driving process of vehicle, if the wearing depth of flower-pattern layer is less than installing blind 11 in present tire ontology 1
Hole it is long, then magnetic bead 2 can will not still fall off, then Hall sensor 31 can be felt in the tire body 1 from tire body 1
The detection magnetic field of the generation of magnetic bead 2 should be arrived, then Hall sensor 31 generates the second sensed data hair according to the detection magnetic field experienced
It send to detection chip 32.And when the hole that the flower-pattern layer wearing depth of tire is greater than outside blind hole in installing blind 11 is long, magnetic bead 2
Tire can be detached from the abrasion of flower-pattern layer in tire.At this point, Hall sensor 31 can not incude the detection magnetic of the generation of magnetic bead 2
, the detection magnetic field that Hall sensor 31 receives in other words is zero, then Hall sensor 31 generates the first sensed data and sends
To detection chip 32.Detection chip 32 generates the first testing result data according to the first sensed data, or according to the second induction number
According to the second testing result data of generation, and pass through radio frequency transmission chip 33 for the first testing result data or the second testing result number
According to tire parameter detection system is sent to, tied to tire parameter detection system according to the first testing result data or the second detection
Fruit data determine the abrasion condition of present tire, for example, when tire parameter detection system receives the first testing result data,
Issue the warning message of " tire wear situation is serious, needs replacing tire ".First testing result data can be understood as representing
Present tire wearing depth is more than the result data of default tolerance wearing depth, and the second testing result data can be understood as generation
Table present tire wearing depth has not exceeded the result data of default tolerance wearing depth.Tire parameter detection system can be
It is set in current vehicle, is also possible to be set in server.
In addition, the tire in the utility model embodiment further includes battery (not marking in figure) and tire identification code (in figure

After tyre vulcanization is cooling, magnetic bead 2 is filled in the inside blind hole of installing blind 11 by the manipulator for carrying magnetic bead 2,
Then rubber seal installing blind 11 is inserted to installing blind 11, magnetic bead 2, which is fixed in tire, to be dropped out.
Step 120, bottom on the inside of tire body is bonded in for tire wear degree detection device is corresponding with magnetic bead by vulcanizing agent
Portion；
Specifically, this step needs two or more manipulators to realize.Firstly, it is necessary to by tire erect and it is longitudinal
Original place rotation, the magnetic bead 2 being embedded in tire body 1 at this time can be moved with the rotation of tire.Tire wear will be carried
First manipulator of degree detection device 3 is set at the pre-determined distance on the inside of tire.When tyre rotation, the first manipulator according to
The detection magnetic field size that tire wear degree detection device 3 is experienced determines tire wear degree detection device bottom on the inside of tire body
The setting position in portion.Then, the second manipulator is polished according to setting position, after the tire tread at cleaning setting position, and first
Manipulator by tire wear degree detection device 3 and bonds tire body inside bottom by vulcanizing agent, at this point, tire wear degree is examined
It is corresponding with position of the magnetic bead 2 in tire to survey position of the device 3 in tire, so that tire wear degree detection device 3 can be with
Sense the detection magnetic field that magnetic bead 2 generates.
Further specifically, when tire wear degree detection device 3 senses detection magnetic field caused by magnetic bead 2, control
Tire stops operating, and tire wear degree detection device 3 is then tire wear degree detection device 3 relative to the position of tire at this time
Setting position in tire body 1.At this point, the second manipulator (manipulator for removing other stations outside the first manipulator) is beaten
Tire tread at mill, cleaning setting position, after the completion of polishing cleaning, the first manipulator is examined tire wear degree by vulcanizing agent
It surveys device 3 to be bonded at setting position, to realize that tire wear degree detection device 3 and magnetic bead 2 are correspondingly arranged at tire body 1
Inside bottom.
Step 130, the detection magnetic field that tire wear degree detection device induction magnetic bead generates, and felt according to detection magnetic field
Answer data；
Specifically, with the abrasion of tyre tread layer, burying can with the magnetic bead 2 in tire in the driving process of vehicle
It can be detached from tire.When the hole that the flower-pattern layer wearing depth of tire is greater than 11 outside blind hole of installing blind is long, magnetic bead 2 can be with
The abrasion of flower-pattern layer in tire and be detached from tire.The Hall sensor 31 in tire wear degree detection device 3 can not just be felt at this time
The detection magnetic field for answering magnetic bead 2 to generate, the detection magnetic field that Hall sensor 31 receives in other words is zero, then Hall sensor 31 is raw
The detection chip 32 in tire wear degree detection device 3 is sent at the first sensed data.And if spent in present tire ontology 1
The hole that the wearing depth of lamina is less than 11 outside blind hole of installing blind is long, then magnetic bead 2 still can be in tire body 1, Bu Huicong
It falls off in tire body 1, then Hall sensor 31 can sense the detection magnetic field that magnetic bead 2 generates, then Hall sensor 31
The second sensed data, which is generated, according to the detection magnetic field experienced is sent to detection chip 32.
Step 140, it will test result data and be sent to tire parameter detection system；
Specifically, detection chip 32 generates the first testing result data according to the first sensed data, or according to the second induction
Data generate the second testing result data.First testing result data can be understood as representing present tire wearing depth
The result data of default tolerance wearing depth, the second testing result data can be understood as representing present tire wearing depth still
It is less than the result data of default tolerance wearing depth.Then core is sent by the inspection radio frequency in tire wear degree detection device 3
First testing result data or the second testing result data are sent to tire parameter detection system by piece 33, are examined to tire parameter
Examining system determines the abrasion condition of present tire according to the first testing result data or the second testing result data.For example, when wheel
When tire parameter detecting system receives the first testing result data, " tire wear situation is serious, needs replacing tire " is issued
Warning message.
