The method and system of the automatic dialing emergency number based on T-Box of the present invention, T-Box are controlled by air bag
Communication between unit, body control system and T-Box can realize the automatic dialing of emergency number based on T-Box, so as to
It is enough to seek to rescue in time, the life security of the wounded is ensured to the maximum extent.
As shown in Figure 1, in an embodiment, the method for the automatic dialing emergency number of the invention based on T-Box includes
Following steps：
Step S1, the broadcast message that acquisition body control system is sent.
Specifically, in the present invention, air bag control unit (Airbag Control Unit, ACU) is by air bag
Status information is sent to body control system (Body Control System, BCM) in real time, for the body control system
Judge whether vehicle collides according to the air bag status information.Specifically, when the air bag status information is
When opening, show that vehicle collides, then the body control system judges that vehicle collides；When the air bag state
Information is when closing, to show that vehicle does not collide, then the body control system judges that vehicle does not collide.
Preferably, it is an on-off model that the air bag, which opens information, and for lighting and (opening quick-fried) SRS, signal is held
Continuous 0.1S, i.e. 100ms.
Body control system is communicated by Body Control bus B CAN with T-Box.Specifically, body control system is pressed
It broadcasts the message to T-Box according to certain frequency.When body control system receives the air bag state letter of air bag opening
When breath, i.e., will include that the broadcast message of vehicle collision signal is sent to T-Box.Correspondingly, T-Box is also according to certain frequency
Acquire the broadcast message that body control system is sent.
Whether step S2, detect in the broadcast message includes vehicle collision signal.
Specifically, T-Box parses received broadcast message, with judge in the broadcast message whether include
There is vehicle collision signal.
Step S3, when including vehicle collision signal in the broadcast message, scheduled emergency number is dialed.
Specifically, after T-Box parses the broadcast message, vehicle collision signal is obtained, then passes through the movement of itself
The scheduled emergency number of wireless communication module automatic dialing, to send out Emergency Assistance request at the first time, to the maximum extent
Protect the life security of the wounded.
Preferably, the scheduled emergency number includes one kind in 110,120 or combination.
In one embodiment of the invention, the method for the automatic dialing emergency number of the invention based on T-Box further includes working as
When this emergency number is dialed unsuccessfully, continue to dial the emergency number pre-determined number；When this emergency number abnormal interrupt,
Turn on automatically calls back.Specifically, T-Box can dial the emergency number of certain number, to ensure aid request can and
When send out.Meanwhile if emergency number is by meaning abnormal interrupt, T-Box T-Box allow rescue center's clawback T-Box phones, T-
Box calls back turn on automatically rescue center, to ensure the unimpeded of call connection.Preferably, add up to dial the rescue
Phone 3 times.

Judge whether vehicle collides according to the air bag status information.Specifically, when the air bag status information is
When opening, show that vehicle collides, then the body control system judges that vehicle collides；When the air bag state
Information is when closing, to show that vehicle does not collide, then the body control system judges that vehicle does not collide.
Preferably, it is an on-off model that the air bag, which opens information, and for lighting and (opening quick-fried) SRS, signal is held
Continuous 0.1S, i.e. 100ms.
Body control system is communicated by Body Control bus B CAN with T-Box.Specifically, body control system is pressed
It broadcasts the message to T-Box according to certain frequency.When body control system receives the air bag state letter of air bag opening
When breath, i.e., will include that the broadcast message of vehicle collision signal is sent to T-Box.Correspondingly, T-Box is also according to certain frequency
Acquire the broadcast message that body control system is sent.
Whether detection module 22 is connected with acquisition module 21, include vehicle collision letter for detecting in the broadcast message
Number.
Specifically, T-Box parses received broadcast message, with judge in the broadcast message whether include
There is vehicle collision signal.
Module 23 is dialed with detection module 22 to be connected, for when including vehicle collision signal in the broadcast message,
Dial scheduled emergency number.
Specifically, after T-Box parses the broadcast message, vehicle collision signal is obtained, then passes through the movement of itself
The scheduled emergency number of wireless communication module automatic dialing, to send out Emergency Assistance request at the first time, to the maximum extent
Protect the life security of the wounded.
Preferably, the scheduled emergency number includes one kind in 110,120 or combination.
In one embodiment of the invention, in the system of the automatic dialing emergency number of the invention based on T-Box, mould is dialed
Block 23 is additionally operable to when this emergency number is dialed unsuccessfully, continues to dial the emergency number pre-determined number；When this rescue electricity
When talking about abnormal interrupt, turn on automatically calls back.Specifically, T-Box can dial the emergency number of certain number, to ensure to rescue
Helping request can send out in time.Meanwhile if emergency number is by meaning abnormal interrupt, T-Box T-Box allow rescue center's clawback
T-Box phones, T-Box call back turn on automatically rescue center, to ensure the unimpeded of call connection.Preferably, add up
Dial the emergency number 3 times.
In one embodiment of the invention, in the system of the automatic dialing emergency number of the invention based on T-Box, further include
Sending module, for current GPS information to be sent to call for service server.Specifically, while making rescue call, T-
Box also accesses rescue center server based on the mobile radio telecommunications module data link of itself, and by the GPS of current T-Box
Information uploads to rescue center server, consequently facilitating rescue center obtains vehicular seat at the first time, to be to rescue in time
Offer Informational support is provided.
