Description
A kind of tire monitor system technical field
The present invention relates to running security technology area, more particularly to tire pressure, temperature monitoring and thermoacoustic prime engine technology refer specifically to a kind of tire monitor system.Background technology
Influence of the tire to running safety is constantly subjected to automobile industry and the concern of the public, and the U.S. started to enforce tire pressure monitoring system in 2003（TPMS) match somebody with somebody for car gage and postpone, TPMS has become automotive engineering proper noun, and rapid growth trend occur in worldwide TPMS development ＆ productions.
Existing TPMS mainstream technology scheme is：TPMS by Liang Bu Fen Group into：Long-range wheel railway platform pressure monitoring module in automobile tire（RTPM：Remote Tire Pressure Moni toring) and central monitor on vehicle cab（LCD display）.Remote pressure monitoring modular in each tire is powered by the sub- battery of lithium, is monitored sampling to tire pressure and temperature, sampled data passes through high frequency radio wave F) to launch, a set of TPMS systems have 4 or 5（Including spare tire）RTPM modules.Central monitor receives the signal of remote tyre pressure monitoring modular transmitting, and each tire pressure and temperature data are sequentially displayed on liquid crystal display, is referred to for driver.If exception occur in tire pressure or temperature, central monitor sends different alarm signals according to abnormal conditions, reminds driver to take necessary measure.Its typical technology route or theory diagram are as shown in Figure 1.
Wherein, remote tyre pressure monitoring modular is made up of some：（1) there is pressure, temperature, acceleration, voltage detecting and the intelligence sensor of rear signal transacting asic chip combination；（2 )4 - 8Position monolithic（MCU )； (3) RF radio-frequency transmissions chips；（4) the sub- battery of lithium；（5) antenna.
Intelligence sensor is silicon micromachining（MEMS) the on-chip system module of fabrication techniques, including pressure sensor, temperature sensor, accelerometer, battery voltage detection, internal clocking and one include analog-digital converter（ADC), sampling/holding（S/H), SPI mouthfuls, calibration（Cal ibrat ion), data management（Data there is), the Digital Signal Processing ASIC units of ID codes, module mask-programmable, i.e. client can be configured using special-purpose software.
Prior art TPMS is powered using the sub- batteries of Lithium to RTPM, and RTPM by battery capacity due to being restricted, and the minimum power designs of battery management are using sleep and timing wake-up scheme after sampling, to meet
Battery uses the requirement of 5 ~ 10 years.Under TPMS modes, the data such as pressure and temp are by the way of large-spacing sampling, usually, pressure data sample frequency is l/3Hz ~ l/8Hz, data transmission frequency is l/30Hz ~ l/80Hz, accurately controlled by RTPM power supply of microprocessor management program, RTPM timing wake-ups time interval is typically fixedly installed as 3 ~ 8 seconds scopes, double sampling interim RTPM modules are in sleep state.
TPMS is to keeping tire normal barometric pressure, prevention and the reduction accident of blowing out to have positive role and effect.But existing TPMS systems are because the tire pressure information sampling interval is up to 3000 ~ 8000 milliseconds, and there is certain limitation or defect, only tire pressure, temperature information prompt facility, in terms of effect is confined to early warning prevention, can not to burst blow out or quick air releasing responds and provided immediately effective relief, this is prior art TPMS feature.Say from the strict sense, existing TPMS should be defined as information alert early warning system.
Existing correlative study data shows that it is unexpected incidents to blow out, in advance without sign that is obvious or determining, it is impossible to fundamentally avoid.The reason for initiation is blown out is tire air pressure, particularly temperature rise, the inside tires of the relatively low initiation of tire pressure（Between rubber and wirecord fabric）Friction, causes rubber for tire layer localized hyperthermia, and rubber is peeled off with casing ply, embrittlement, ultimately results in tyre break.Tire pressure is relatively low, to run at high speed for a long time be the major incentive blown out.
American scholar Wesley D. Grimes are delivered《Three-dimensional artificial of the vehicle to reaction of blowing out》(3-Dimens ional Simul tion of Vehicle Response to Tire Blow-outs) research report shows, blow out generation when, air pressure is lost in 100 Bos second in tire, vehicle wheel roll radius of blowing out reduces, blow out wheel rolling, resistance increase is more than 30 times before blowing out, blow out wheel and wheel in diagonal positions declines to the normal pressure Fz on ground, side-friction force also declines therewith, there is wheel rim tire is rolled in the process wheel that continues then to blow out, roll until tire tear is separated with wheel rim, side-friction force is caused to decline to a great extent.During tire is rolled and is torn, tire and ground surface resistance, which significantly increase, to be even resulted in wheel and switchs to slide by rolling（When wheel of blowing out is driven pulley）, a lateral force is formed, automobile is occurred the motion for deviateing travel direction.
Wes ley D. Grimes research report shows simultaneously, simple blowing out not necessarily causes the generation of accident, specific road conditions when whether the operation that driver makes to information of blowing out is correct and blows out residing for vehicle, to whether triggering traffic accident to there are direct correlation , Te Do to point out driver's oversteering and excessively braking after quick-fried stock（It is seized）The generation of accident is likely to result in, on the contrary, the manipulation of driver suitably（Adjustment maintains driving trace and appropriateness to brake）, it would be possible to avoid the generation of accident.
The research report conclusion disclose one it is particularly important the fact：After the generation 2 ~ 3 seconds of blowing out
At the time of, driver can make a response from the time, and appropriateness manipulation of the driver to automobile is still considered as being necessary and required, and danger of being blown out to neutralizing plays an important roll.The content of the invention
