Embodiment
Embodiment of the invention solution mainly is through waking cooperatively interacting of terminal and server and tire pressure monitoring module up, through waking terminal wake-up tire pressure monitoring module up.
Tire pressure monitoring system can be BMBS in the embodiment of the invention, also can be TPMS, is that BMBS is that example is elaborated to technical scheme of the present invention below with the tire pressure monitoring system, and technical scheme of the present invention is equally applicable to the situation that tire pressure monitoring system is TPMS.
As shown in Figure 1; One embodiment of the invention proposes a kind of tire pressure monitoring module and wakes the terminal up; Be specially a kind of BMBS Vehicular intelligent debugging appearance and wake the terminal up, comprising: central controller 101, low frequency driving circuit 102, low frequency wireless transmitting unit 103 and power supply unit 104; Wherein:
Low frequency driving circuit 102 is used for waking data according to driving order up to 103 transmission of low frequency wireless transmitting unit;
Low frequency wireless transmitting unit 103 and 106 wireless connections of tire pressure monitoring module; Be used for sending the low frequency wake-up signal to the tire pressure monitoring module 106 of detected tyre according to waking data up; With tire pressure monitoring module 106 in waking up, realize that specifically tire pressure monitoring module 106 and tire pressure monitoring system main frame carry out matching test;
Further, this wakes the terminal up and also comprises the warning lamp that serves as warning 107 that is connected with central controller 101, and this warning lamp 107 is opened and closed by central controller 101 controls.
Further, this wakes the terminal up and also comprises low frequency wireless strengths debugging module 108, is used to debug the intensity of the low frequency wake-up signal that low frequency wireless transmitting unit 103 sends.
Like Fig. 2, shown in 3, present embodiment wakes terminal each functional module shown in Figure 1 up and is arranged in the casing 1 that wakes the terminal up, and casing 1 adopts the thick angle bar of 2.5mm to be welded.
As shown in Figure 4; In the present embodiment; Waking that terminal and detected tyre 2 laterally arrange up is that casing 1 laterally arranges with detected tyre 2; It is moving with respect to the location portability of detected tyre 2 to wake the terminal up, and wakes the terminal up and on the direction axial perpendicular to detected tyre 2, be-500mm-500mm with respect to the moving range in detected tyre 2 axle center.Wake the terminal relatively up, as shown in Figure 4, detected tyre 2 is 1000mm with respect to the moving range of waking the terminal up.When installing and using, can come into operation after waking installation site, terminal and detected tyre 2 relative position secured in parallel up.After detected tyre 2 placement locations are fixing; In the Validity Test scope; No matter tire pressure monitoring module 106 in the detected tyre 2 is in any angle of detected tyre 2 circumference, can both be waken up the terminal and effectively wake up, and promptly the low frequency wake-up signal covers the whole tire at corresponding tire pressure monitoring module 106 places.
That wakes the terminal in the present embodiment up wakes≤1.2 meters of distances up, promptly wakes terminal casing 1 up apart from axial distance≤1.2 of detected tyre 2 meter.Wherein, when waking the axial distance of terminal casing 1 up and be 0.3～0.6 meter apart from detected tyre 2, low frequency wake-up efficient >=90%.

Below specify the tire pressure monitoring module that present embodiment is applied to BMBS Vehicular intelligent debugging appearance and wake the principle of work at terminal up:
Present embodiment tire pressure monitoring module is waken the terminal up and is installed in the BMBS Vehicular intelligent debugging appearance, and this wakes the terminal up and cooperates the learning process of accomplishing BMBS tire pressure monitoring module 106 promptly to accomplish the matching test of BMBS tire pressure monitoring module 106 and BMBS main frame with server 105 and the BMBS tire pressure monitoring module 106 that the BMBS Vehicular intelligent is debugged in the appearance.
Behind system power-on reset, wake the terminal up under the control of central controller 101, accomplish each functional module initialization procedure, and open all warning lamps 107, wake the terminal up with the prompting staff and start working.The warning lamp 107 that wakes the terminal up can be through the order control its " unlatching " or " closing " of server 105.After waking terminal initialization up, send and confirm that then communication is normal after order to the server 105 of shaking hands is waited for " correctly " commands in return.Or etc. the order and reply " correctly " order of shaking hands of server 105 to be detected to confirm that communication normally.
Afterwards, wake terminal juncture up the signal of communication from peripheral hardware is monitored, and the signal of communication that monitoring receives is resolved back formation driving order, drive the corresponding function module action.Be specially:
Receive the wake command of BMBS Vehicular intelligent debugging appearance server 105 transmissions when the central controller that wakes the terminal up 101 after; Central controller 101 sends to low frequency driving circuit 102 according to wake command and drives order, transmits 125KHz by low frequency driving circuit 102 according to the driving order and wakes data tremendously low frequency wireless transmitting unit 103 up.Low frequency wireless transmitting unit 103 is sent the low frequency wake-up signal according to waking the BMBS tire pressure monitoring module 106 of data in detected tyre 2 up; To wake BMBS tire pressure monitoring module 106 up; BMBS tire pressure monitoring module 106 is learnt, thereby accomplished the matching test of BMBS tire pressure monitoring module 106 and BMBS main frame.
After BMBS tire pressure monitoring module 106 learning motion in five tires of automobile are accomplished, server 105 will be tested to the learning outcome of BMBS main frame feedback.At first from the BMBS main frame, read the ID sign indicating number of all position of wheel tire pressure monitoring modules, judge whether the ID sign indicating number is legal,, then directly judge the study failure result as illegal.As legal; Then further wake each position of wheel BMBS tire pressure monitoring module 106 of terminal wake-up up through present embodiment; BMBS tire pressure monitoring module 106 signals through the actual result of obtaining are that BMBS tire pressure monitoring module 106 information of storing in detecting information and the BMBS main frame are that above-mentioned learning outcome is complementary; Matching result is reasonable, then judges learning success.As be judged as learning success, then with display that server 105 is connected on show " XX take turns study--success " successively, as be judged as the study failure, show then " XX takes turns study--fail ", and the recording operation result that the outcome record of will makeing mistakes arrives print area.
Embodiment of the invention tire pressure monitoring module is waken the terminal up, through waking cooperatively interacting of terminal and server 105 and tire pressure monitoring module 106 up, has realized waking up tire pressure monitoring module 106 in the tire pressure monitoring system; From having realized the coupling of tire pressure monitoring module 106 with system host; Debug process is carried out Intellectualized monitoring, realized the intellectuality debugging of product effectively, improved the reliability of entire system debugging at the car load production line; Reduce the debugging station running time; Brief debug process promoted production efficiency, and the debug results of debugged product has trackability.
The above is merely the preferred embodiments of the present invention; Be not so limit claim of the present invention; Every equivalent structure or flow process conversion that utilizes instructions of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present invention.
