Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the integral structure scheme drawing of the reliable monitoring system of this redundancy;
Fig. 2 is the scheme drawing that concerns of tire drag and tire pressure.
The specific embodiment
As shown in Figure 1, the reliable monitoring system of redundancy provided by the utility model comprises a upper module of car load and the next module of a plurality of tire, wherein the upper module of car load is installed in automotive interior, is made up of reliable starting unit, multipath alarm unit and emergency handling unit three parts; The next module of tire is installed in the inside of each motor tire, is made up of redundant measurement unit and site disposal unit two parts.Adopt wireless mode to communicate between the next module of each tire and the upper module of car load.Reliable starting unit in the upper module of car load has the on-vehicle information interface, and the multipath alarm unit has remote network interfaces, and the emergency handling unit then has vehicle-mounted driving interface.
Being different from prior art only adopts single-sensor to carry out the measurement of tire internal state, a distinguishing feature of the reliable monitoring system of this redundancy is to be provided with multiple sensors in the redundant measurement unit, is respectively applied for to realize the measurement of motor tire pressure inside, temperature survey, humidity measurement, electrical measurement and motional induction.These sensors adopt the redundant configuration mode, promptly at same measurement purpose a primary sensor and at least one backup sensor are set, the measured signal of the independent respectively transmission of each sensor.In addition, the wireless communication interface between the next module of tire and the upper module of car load also adopts similar redundant configuration mode.So just can guarantee still can obtain after primary sensor or wireless communication interface lost efficacy the correct information of the inner work condition state of motor tire.
Above-mentioned redundant measurement unit is connected with the site disposal unit.Embedded microprocessor in the next module of this site disposal unit by using tire carries out site disposal, comprises information acquisition, analysis and judgement, data upload, shielding switching, dormancy or wake up.Wherein information acquisition is meant information such as motional induction, pressure survey, temperature survey, humidity measurement, electrical measurement is gathered.Analysis and judgement is meant according to the metrical information that collects, and utilizes the inherent mechanism of situ configuration scheme to analyze, and judges whether should carry out dormancy or wake up; Data upload; Shielding and switching.
The effect of the reliable starting unit in the upper module of car load is: the upper module of car load has been known automobile start and smooth running from vehicle-mounted information interfaces such as automobile CAN-bus or GPS receivers, but slowly do not obtain the data of uploading of the next module of certain tire, say the word then for the next module of this tire and require to upload data, perhaps require to carry out the active and standby switching of motional induction sensor, otherwise switch communication interface.
The LED that multipath alarm unit in the upper module of car load not only has prior art to be adopted shows and the caution acoustic alarm, and to adopt the specific audio alert that presets (can be Chinese as " right front tire leaks gas slowly ", also can be other countries' language or dialect, have default presetting and the setting of can recording), comprise by wireless network to remote alarms.
(reporting to the police as alcoholic strength " little drink " or fatigue strength " yellow ") for information about of chaufeur ability drop known based on the on-vehicle information interface in emergency handling unit in the upper module of car load, can be by vehicle-mounted driving interface automatic guidance car deceleration, keep to the side and stopping-down etc.
As direct-type tire condition monitoring system, no matter be active from charged pool, still utilize the passive type of tire motion generating, or utilize hybrid that the motion generating charges the battery, from the angle of reliability, all be necessary to carry out managing electric quantity.When the electrical measurement sensor reflects that the electric weight deficiency should be reported to the police, just report to the police by the site disposal unit.
From reducing the angle of power consumption, reliably monitoring system just should dormancy for this redundancy when the automobile parking tire is static, when the work of just wakeing up of getting up of car engine tyre rotation.For this reason, the motional induction sensor detects the rotation and the static situation of tire, and the embedded microprocessor in the next module of tire determines to wake up work or dormancy according to testing result.When tire just by static to rotating, the next module of tire should continue to send current tire condition data to the upper module of car load.
If all are normal for the primary sensor of working, how to judge according to metrical information whether the tire condition is normal, if it is not serious unusually also to need judgement to be critical.Account for absolute status because upload the electric weight that communication consumes, will frequently upload communication and report to the police if be critical, if not serious then medium frequency report to the police, if normally sparse frequency report to the police.For example temperature too high easily cause blowing out just very serious; Tire gas leakage fast is also very serious.
With the tire pressure is example, and for example the optimum value of certain motor tire internal pressure is 2.5 barometric pressures, and as shown in Figure 2, tire can also the car load operation greater than 2.0 the time when tire pressure; But if tire pressure is lower than 2.0 and when continue descending, the resistance of tire rolling operation will significantly increase.Embedded microprocessor in the next module of tire can judge whether tire pressure is unusual according to the relation of tire drag and tire pressure shown in Figure 2, is to leak gas slowly or fast gas leakage.
On the other hand, do you how can know just that the primary sensor itself of working occurs unusual? this can have multiple settling mode, if for example can not get take off data, perhaps mess code appears in take off data always, and the embedded microprocessor in the next module of tire just can judge independently that primary sensor lost efficacy.Learning by the on-vehicle information interface that automobile has started when the upper module of car load and travel, when the next module of tire is not then uploaded relevant data, then might be that the main motion coil pickup is unusual.Finding abnormal tyre pressure when time-based maintenance is safeguarded, and do not obtain reporting to the police when travelling recently, also might be that primary pressure sensor lost efficacy.
Embedded microprocessor in the next module of tire finds that primary sensor is unusual, then should detect interface from main shield, changes automatically by the backup sensor interface to obtain take off data.If find that by other modes primary sensor is unusual, then give an order for the next module of tire by the upper module of car load, the next module of tire shields the respective detection interface after receiving order, changes automatically by the backup sensor interface to obtain take off data.
More than the redundant reliable monitoring system of the inner operating mode of motor tire provided by the utility model is had been described in detail, but obvious specific implementation form of the present utility model is not limited thereto.For the those skilled in the art in present technique field, in the various conspicuous change of under the situation that does not deviate from claim scope of the present utility model it being carried out all within protection domain of the present utility model.
