Description
Technical field
This utility model belongs to automobile assembling field, is specifically related to a kind of wheel detector calibration system.
Background technology
Tire pressure monitoring system (TPMS) has been widely used on the passenger cars such as car minibus, can not get for a long time solving owing to the many tires of truck trigger the technical bottleneck demarcated, thus constrain the application in commercial car of the TPMS system, especially have impact on the development of truck enterprise security Auxiliary System.The load-carrying of truck relies on multiaxis, many tires load sharing weight, and the two ends of axletree are all that two wheels are installed side by side.If compartment is two axles, four wheels that the same end at two axles is then provided with and close proximity, the sensor namely meaned in four tires there may come a time when close proximity.When using existing triggering scaling method to wherein tire timing signal, due to the transmission characteristic that LF low frequency radio wave spreads to surrounding, it is easy to received by the sensor outside target tire and activate by mistake.Prior art is that trigger first triggers demarcation, is attached on trigger by calibrated position of wheel coding, is then arranged on by sensor on axletree and the position of wheel of correspondence one by one further in accordance with position of wheel coding, can not arranged in dislocation, otherwise can not play the safety precaution function of TPMS.But, owing to above-mentioned demarcation, dress tire and entrucking are not same scenes, easily there is mistake in operation link, it is impossible to adapts to truck enterprise and produces the traditional thread binding requirement joined.
Utility model content
The purpose of this utility model is to provide a kind of it can be avoided that wheel detector demarcates the wheel detector calibration system of mistake.
For achieving the above object, this utility model provides techniques below scheme: a kind of wheel detector calibration system, including electronic control unit, low frequency signal transmitter unit and rf signal reception unit, described electronic control unit produces to trigger signal, this triggering signal transmissions tremendously low frequency signal transmitter unit, triggering signal is wirelessly transmitted to target carriage wheel sensor by directional transmission antenna by low frequency signal transmitter unit, target carriage wheel sensor can send, after receiving triggering signal, the answer signal comprising this sensor ID information of identification code, described rf signal reception unit receives this answer signal, and by this answer signal transmission to electronic control unit.
Of the present utility model have the technical effect that this utility model adopts directional transmission antenna low frequency to trigger signal directive sending to target carriage wheel sensor, avoid neighbouring wheel detector to activate by mistake, additionally this utility model adopts reaction type power gradual change to trigger, start from default lowest power to incrementally increase the power triggering signal, until target carriage wheel sensor sends answer signal, guarantee to trigger signal so that power is minimum and the minimum activation target carriage wheel sensor of toggle area, further avoid neighbouring wheel detector and activated by mistake.

Detailed description of the invention
As shown in Figure 1, a kind of wheel detector calibration system, including electronic control unit 10, low frequency signal transmitter unit 11 and rf signal reception unit 12, described electronic control unit 10 produces to trigger signal, this triggering signal is wirelessly transmitted to target carriage wheel sensor by low frequency signal transmitter unit 11 by directional transmission antenna 13, target carriage wheel sensor can send, after receiving triggering signal, the answer signal comprising this sensor ID identification code, described rf signal reception unit 12 receives this answer signal, and by this answer signal transmission to electronic control unit 10.
As shown in Figure 2, described directional transmission antenna 13 includes exciting unit 1, antenna oscillator 2 and boundling cover 3, described exciting unit 1 and antenna oscillator 2 are installed in boundling cover 3, the shell structure of the one end open that described boundling cover 3 is made up of high magnetic conductive metal material, described exciting unit 1 is connected with low frequency signal transmitter unit 11 by a feeder line 4.
Preferably, described boundling cover 3 includes cone tubular sidewall and circular bottom wall, described circular bottom wall is positioned at the miner diameter end of cone tubular sidewall, described exciting unit 1 and antenna oscillator 2 are arranged in circular bottom wall, the through wires hole extraction that described feeder line 4 is reserved circular bottom wall, is then connected with low frequency signal transmitter unit 11.This utility model is mainly used in the demarcation of truck tyres sensor, the distribution of truck tyre generally ratio comparatively dense, the scattered signal that tradition calibration facility is launched can be received by multiple tire sensors simultaneously, and then these tire sensors can respond simultaneously, cause operator cannot judge these feedback signals which wheel corresponding respectively.This utility model then can allow the wireless signal of marking apparatus launch towards assigned direction, the opening of boundling cover 3 only need to be directed at the valve cock specifying wheel by operator, just individually can set up with the sensor of this wheel and communicate, it is not necessary to worry the interference of other wheel detectors.It addition, the length of feeder line 4 can select according to the actual requirements, the length of feeder line 4 it suffices that: boundling cover 3 can be made to extend into the valve cock position of truck inside tire.
Further, described electronic control unit 10 is further connected with display screen 14 and keyboard 15.The position of wheel of each wheel can be shown by display screen 14 in a schematic manner, it is simple to operator distinguish, keyboard 15 includes model selection, triggers the buttons such as switch, it is simple to technical staff accurately manipulates.
As it is shown on figure 3, the control method of this utility model calibration system comprises the following steps:
A. on keyboard 15, select low frequency trigger mode；
B. under display screen 14 is pointed out, select target wheel；
C. by the opening of the boundling cover 3 of directional transmission antenna 13 as far as possible close to target carriage wheel sensor；
D. the trigger key on lower keyboard 15 is pressed, the low frequency signal transmitter unit 11 of system works, low frequency ASK is modulated signal with default lowest power by low frequency signal transmitter unit 11, it is radiated to target carriage wheel sensor by directional transmission antenna 13, now, the rf signal reception unit 12 of system is in reception state, wait wheel detector be triggered after answer signal；
E. in above-mentioned steps d, if the rf signal reception unit 12 of system is not received by the answer signal of sensor, then the electronic control unit 10 of system triggers after the transmitting power of low frequency signal transmitter unit 11 being improved with the stepping of 1dB again, till wheel detector is activated transmission answer signal；
F. the sensor ID identification code in record answer signal, demarcation completes.
This utility model adopts directional transmission antenna low frequency to trigger signal directive sending to target carriage wheel sensor, avoid neighbouring wheel detector to activate by mistake, additionally this utility model adopts reaction type power gradual change to trigger, start from default lowest power to incrementally increase the power triggering signal, until target carriage wheel sensor sends answer signal, guarantee to trigger signal with minimum received activation target carriage wheel sensor, further avoid neighbouring wheel detector and activated by mistake.
