After recognizing information, MSD information is sent to car-mounted device 2, receiving module 600 receives and keeps in the MSD information.
Whether the detecting of the second detecting module 800, which connects, is connected to the Net.Specifically, the second detecting module 800 is vehicle-mounted by detecting
Whether device 2, which connects, is connected to the Net, to judge whether for the urgent call flag information and the MSD information to be forwarded to
PSAP。
Forwarding module 900 is used to turn the urgent call flag information and the MSD information when even connecting to the Net
PSAP is sent to notify the PSAP to assign rescue task.
Computing module 1000 calculates the storage duration of the MSD information.
In a preferred embodiment, when receiving module 600 receives the MSD information, computing module 1000 starts to count
Calculate the storage duration of the MSD information.
Second judgment module 1100 judges whether the storage duration is more than preset time.
Module 1200 is removed to be used to remove the MSD information when the storage duration is more than the preset time.
In a preferred embodiment, if the storage duration of the MSD information is more than preset time, then it represents that car-mounted device 2
It reports a case to the security authorities time-out, in order to avoid PSAP also receives repetition rescue and reports a case to the security authorities after missing best rescue time, then removes module 1200
By the MSD erasing of information.
As shown in fig.3, being the step flow chart of the communication means of the embodiment of the present invention.The communication means is applied to vehicle
It carries and sets in 1, the program code stored in memory 20 is executed by processor 30 and is realized.
Step S300, whether detecting vehicle occurs accident, if accident occurs, thens follow the steps S302, otherwise continues to execute
S300。
Step S302, triggering emergencycallboxsystem send MSD information to PSAP.
Whether step S304, detecting receive the reception confirmation that the PSAP is fed back after receiving the MSD information
Signal thens follow the steps S306 if receiving the reception confirmation signal, no to then follow the steps S308.
Step S306 issues warning information.
Step S308, by 4G LTE direct mode with prefixed time interval broadcasting emergency call sign information to week
Other car-mounted devices enclosed, wherein the urgent call flag information is a kind of information for identifying emergent type of call.
Step S310 judges whether to receive other described car-mounted devices after receiving the urgent call flag information
The reception confirmation message of feedback thens follow the steps S312, otherwise continues to execute step if receiving the reception confirmation message
S308。
The MSD information is sent to other car-mounted devices and issues warning information by step S312, with by it is described other
The urgent call flag information and the MSD information are forwarded to the PSAP by vehicle fitting.
As shown in fig.4, being the step flow chart of the communication means of another embodiment of the present invention.The communication means application
In car-mounted device 2, the program code stored in memory 50 is executed by processor 60 and is realized.
Step S400 receives the urgent call flag information that surrounding car-mounted device is sent.The urgent call flag information
It is a kind of information for identifying emergent type of call.
Step S402 feeds back the reception confirmation message of the urgent call flag information to the surrounding car-mounted device.
Step S404 receives and stores the MSD information that the surrounding car-mounted device is sent.
Step S406, whether detecting, which connects, is connected to the Net, if even connecting to the Net, is thened follow the steps S408, is otherwise continued to execute
Step S406.
Step S408, it is described to notify that the urgent call flag information and the MSD information are forwarded to PSAP
PSAP assigns rescue task.
As shown in fig.5, being the step flow chart of the MSD information processing of the embodiment of the present invention.
