Abstract
The utility model discloses an anti-blowout monitoring device for a tyre. The anti-blowout monitoring device comprises a resistance-type anti-blowout tyre sensor and a judgment circuit. The resistance-type anti-blowout tyre sensor is connected to bridge arms of a Wheatstone bridge, and when the tyre swells, two bridges of the Wheatstone bridge are not in balance any longer and output current; the current flows through an operational amplifier circuit and a voltage-frequency conversion circuit to get a trigger signal; the trigger signal is transmitted to an electronic control unit after being analyzed by the judgment circuit for judging whether the trigger signal is an interference signal or a tyre blowout signal; and the electronic control unit controls the operation of a backward stage device. The anti-blowout monitoring device starts to extract a characteristic signal since the tyre swells and increases the operation time of a driver, so that the driver can take effective measures according to the signal, or can stop a vehicle safely, or can avoid the blowout of the tyre by driving in a low speed.
Description
Technical field
The utility model relates to the monitoring technique field, is specifically related to a kind of tire anti-explosion control monitor unit.
Background technology
It is a kind of extremely dangerous situation that high speed traveling is blown out, and regular meeting causes serious accident.Prevent and prevent automobile flat tire harm, its measure generally has initiatively prevention and passive prevention.What initiatively prevention was commonly used is the detection to tire parameter; Require to send timely and accurately signal of tyre burst; For downstream component (emergency pneumatic of blowing out, the intelligence of blowing out are gone, the self-actuating brake etc. of blowing out) provides the trigger sensor condition, thereby require very high to the real-time of signal transducer; And the measurement and the instrument of automobile pressure also mainly adopt piezoelectric transducer, mechanical sensor, trigger sensor at present, and these several types of sensors can not satisfy the signal detection of automobile flat tire in time.Can not in time provide the failure-free energizing signal for downstream component; And traditional monitored control system is only from four aspect synthetic determinations such as pressure, temperature, acceleration/accel and voltages; Be incomplete, because tire is very big from othernesses such as new and old program, the road surface situation of walking, weather aspects.
The utility model content
To above-mentioned prior art, the technical matters that the utility model will solve is: from many aspects monitoring tyres how, cooperate downstream component, and guarantee traffic safety.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of tire anti-explosion control monitor unit is provided; It is characterized in that; Comprise resistance-type runflat sensor, decision circuitry, said resistance-type runflat sensor is connected to the leg of a bridge of Wheatstone bridge, during tire generation bulge; Two bridges of Wheatstone bridge no longer balance have electric bridge output; Said electric bridge output obtains energizing signal through operational amplification circuit, voltage-frequency converting circuit, and said energizing signal transfers to ECU after the decision circuitry analysis is interfering signal or signal of tyre burst, the action of said ECU control downstream component; Said resistance-type runflat sensor comprises gauge line, and said gauge line is designed to flat strip shaped, and is the S shape and is laid in the substrate.
Said decision circuitry comprises voltage-frequency converting circuit, 555 oscillating circuits, output circuit, comparator sum counter.
Compared with prior art, the utlity model has following beneficial effect:
Begin to extract characteristic signal from bulge, increased the operating time of chaufeur, chaufeur can be adopted an effective measure according to signal, perhaps can emergency, or all low speed driving is avoided the generation of blowing out.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
To combine the accompanying drawing and the specific embodiment that the utility model is done further to describe below.
A kind of tire anti-explosion control monitor unit; It is characterized in that; Comprise resistance-type runflat sensor, decision circuitry, said resistance-type runflat sensor is connected to the leg of a bridge of Wheatstone bridge, during tire generation bulge; Two bridges of Wheatstone bridge no longer balance have electric bridge output; Said electric bridge output obtains energizing signal through operational amplification circuit, voltage-frequency converting circuit, and said energizing signal transfers to ECU after the decision circuitry analysis is interfering signal or signal of tyre burst, the action of said ECU control downstream component.Said decision circuitry comprises voltage-frequency converting circuit, 555 oscillating circuits, output circuit, comparator sum counter.
Embodiment
Because resistance sensor is not afraid of crimp; Can be contained in very little space; So a plurality of resistance sensors are installed between casingply, the cushion layer, carcass has any distortion all can have influence on the distortion of strain resistor, can not have influence on the normal use of tire.Automobile is sailed in that the high speed road surface is up; Tire possibility impact crater hole or other foreign matters; Cause tire between alluvium and rim flange, crimp to take place, can cause inside tires cord fabric broken yarn when serious, the air of inside tires can form bulge from broken yarn jack-up.Vary in size according to impulsive force, the time that the tire bulge forms is also different.Impact strength is big, and the cord fabric broken yarn is more, and tire can form bulge very soon; Impact strength when less, the cord fabric broken yarn is less, and bulge at that time might not occur, but after going after a while, broken yarn can increase and then form bulge gradually.Have a time difference between tire bulge and the tire bump foreign matter.Tire bulge meeting produces the increment of a diameter, increment is introduced circuit extract, with its characteristic signal as preparatory signal of tyre burst.
Said resistance-type runflat sensor comprises gauge line, and said gauge line is designed to flat strip shaped, and is the S shape and is laid in the substrate.
Claims (2)
