Abstract
The invention discloses a kind of loop tire pressure monitoring system of high and low frequency, including remote control, transmitter module and vehicle-mounted BCM, the remote control wirelessly connects transmitter module, information exchange is carried out between transmitter module and vehicle-mounted BCM, the transmitter module activates after receiving the control signal from remote control and launches low frequency signal to vehicle-mounted BCM, and the vehicle-mounted BCM receives the low frequency signal firing backward module from transmitter module and sends feedback signal.The present invention is to add high-frequency signal that tire pressure transmitter module and vehicle-mounted BCM are connected into feedback loop system jointly using low frequency, has advantages below：1st, signal transmission is more stable, carries out real time emission by backfeed loop, is monitored in real time when realizing automobilism；2nd, power consumption will be greatly reduced, and increase sensor service life；3rd, received by vehicle-mounted BCM, reduce numerous and diverse wiring and goods of furniture for display rather than for use on car.
Description
Technical field
The present invention relates to a kind of monitoring system, the loop tire pressure monitoring system of specifically a kind of high and low frequency.
Background technology
Tire pressure monitoring be in vehicle traveling process to tire pressure carry out real-time automatic monitoring, and to have a flat tire with it is low
Air pressure is alarmed, to ensure traffic safety.There is data to suggest that by traffic accident caused by blowing out in pernicious traffic accident it is shared
Ratio is up to 70%, and it is first cause that tire pressure deficiency, which is worked as, in all factors that can cause to blow out.This is not to deliberately exaggerate so as to create a sensation, i.e.,
You is not selected the vehicle with tire pressure monitoring, also to improve the attention to vehicle tyre, avoid people and Che that serious damage occurs
Wound.
It is existing suppress monitoring system can only high frequency folk prescription surface launching, can not understand whether signal has received, exist multiple
Or few reception condition, existing technology is ensures that tire pressure monitors the increased power dissipation and multi-emitting this two kinds of situations of use in real time.Cause it
Power consumption increase, wastes the energy.
The content of the invention
It is an object of the invention to provide a kind of loop tire pressure monitoring system of high and low frequency, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the present invention provides following technical scheme：
A kind of loop tire pressure monitoring system of high and low frequency, including remote control, transmitter module and vehicle-mounted BCM, the remote control
Transmitter module is wirelessly connected, information exchange is carried out between transmitter module and vehicle-mounted BCM, the transmitter module receives
Activated after control signal from remote control and launch low frequency signal to vehicle-mounted BCM, the vehicle-mounted BCM, which is received, carrys out spontaneous emission mould
The low frequency signal firing backward module of block sends feedback signal, if transmitter module do not receive always feedback signal will continue to
Vehicle-mounted BCM sends low frequency signal, is alarmed after being transmitted into setting number, when transmitter module receives the feedback signal of vehicle-mounted BCM transmissions
Afterwards, transmitter module just sends high-frequency signal to vehicle-mounted BCM, sends pressure and temp data in real time.
Preferred scheme as the present invention：The feedback signal and low frequency signal are by way of CAN or connecting line
It is transmitted.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is to add high-frequency signal to send out tire pressure using low frequency
Penetrate module and connect into feedback loop system jointly with vehicle-mounted BCM, there is advantages below：1st, signal transmission is more stable, by anti-
It is fed back to road and carries out real time emission, is monitored in real time when realizing automobilism；2nd, power consumption will be greatly reduced, and increase sensor uses the longevity
Life；3rd, received by vehicle-mounted BCM, reduce numerous and diverse wiring and goods of furniture for display rather than for use on car.
Brief description of the drawings
Fig. 1 is the overall block diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to Fig. 1, in the embodiment of the present invention, a kind of loop tire pressure monitoring system of high and low frequency, including remote control,
Transmitter module and vehicle-mounted BCM, the remote control wirelessly connect transmitter module, entered between transmitter module and vehicle-mounted BCM
Row information is interacted, and the transmitter module is activated after receiving the control signal from remote control and believed to vehicle-mounted BCM transmitting low frequencies
Number, the vehicle-mounted BCM receives the low frequency signal firing backward module from transmitter module and sends feedback signal, if transmitting mould
Block does not receive feedback signal always will continue to send low frequency signal to vehicle-mounted BCM, alarmed after being transmitted into setting number, work as transmitting
After module receives the feedback signal that vehicle-mounted BCM is sent, transmitter module just sends high-frequency signal to vehicle-mounted BCM, sends pressure in real time
Temperature data.
Feedback signal and low frequency signal are transmitted by way of CAN or connecting line.
The present invention operation principle be：Remote control activates to transmitter module, launches to the reception at wheel hub axletree
Send low frequency signal, by CAN either connecting line to BCM send data BCM receive signal and by CAN or
Connecting line feeds back to transmitting terminal（Low frequency signal is persistently sent if not receiving always, is alarmed after being transmitted into setting number）, hair
Penetrate end and send high-frequency signal, send pressure and temp data in real time.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the involved claim of limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
