Row solution is anti-, unlock, and passes through CAN bus and communicate with the car-mounted terminal, so that the car-mounted terminal is put down to the remote service
Platform sends information of vehicles, vehicle real time position and the vehicle fire position；When nobody, the car body controller passes through
CAN bus communicates with the car-mounted terminal, so that the car-mounted terminal sends information of vehicles, vehicle to the remote service platform
Real time position and the vehicle fire position.It should be noted that in the embodiment of the present invention, car-mounted terminal is stored with vehicle letter
Breath, and can be by communicating to obtain vehicle real-time position information with GPS (not shown).
In an alternative embodiment of the invention, the car body controller stationary vehicle and in solve anti-state when, such as
Fruit receives fire signal, parses the fire signal and obtains vehicle fire position, then detects vehicle by the seat controller
Inside whether someone；As someone, the car body controller is unlocked all car doors, and pass through CAN bus with it is described vehicle-mounted
Terminal communicates, so that the car-mounted terminal sends information of vehicles, vehicle real time position and described to the remote service platform
Vehicle fire position；When nobody, the car body controller is communicated by CAN bus with the car-mounted terminal, so that the vehicle
Mounted terminal sends information of vehicles, vehicle real time position and the vehicle fire position to the remote service platform.
Automobile fire alarm system provided in an embodiment of the present invention, fire master controller are believed according to the fire of fire sensor
Number control alarm is alarmed, and is passed through car body controller and sent fire information to car-mounted terminal, so that car-mounted terminal passes through
Wireless network and remote service Platform communication, realize remote fire alarm.
Further, when vehicle CAN network breaks down, in order to preferably propagate fire condition, of the invention another
In embodiment, the fire master controller can be connect with the car-mounted terminal by rigid line, when fire master controller receives
The fire signal and when detecting the car body controller failure by LIN buses, the fire master controller parses institute
It states fire signal and obtains vehicle fire position, and pass through rigid line and communicate with the car-mounted terminal, so that the car-mounted terminal is to institute
It states remote service platform and sends information of vehicles, vehicle real time position and the vehicle fire position.Through the embodiment of the present invention,
Urgent remote alarms can be realized when having fire behavior and CAN network failure.
In an alternative embodiment of the invention, fire specific location is understood for the ease of occupant, as shown in figure 4, institute
Stating in vehicle control device can also include：MP5, the MP5 by CAN bus respectively with the car body controller, described vehicle-mounted
Terminal connects, and the MP5 obtains the vehicle fire position from the vehicle body device or the car-mounted terminal, and shows the vehicle
Fire location.Through the embodiment of the present invention, occupant can be made to understand the specific location of vehicle fire in real time, consequently facilitating vehicle
Interior personnel respond in time.
Automobile fire alarm system provided in an embodiment of the present invention, fire master controller is from the fire positioned at vehicle different location
Obtain fire signal in calamity sensor, and by the fire signal by LIN bus transfers to car body controller, car body controller
After obtaining the fire signal, vehicle-state is obtained from engine controller by CAN bus, in stationary vehicle, according to
The signal control vehicle solution of seat controller is prevented or/and is unlocked；When vehicle is run, dropped by engine controller controls vehicle
Speed；Further, when fire master controller breaks down, the supervisory control device that passes through LIN buses with the fire master controller
The fire master controller is taken over to communicate with the car body controller；Further, system further includes：Car-mounted terminal and remote
Journey service platform, the car-mounted terminal can respectively with car body controller, the remote service Platform communication, so as to fulfill fire behavior
Remote alarms；Further, the car-mounted terminal can also be connect with fire master controller by rigid line, when vehicle CAN network
After paralysis, fire master controller sends fire signal to the car-mounted terminal by rigid line, so as to ensure that the long-range of fire behavior
Alarm.In conclusion the present invention realizes timely, the true reflection of vehicle fire state, and can realize that vehicle fire is complete
The alarm in orientation.
For above-mentioned automobile fire alarm system, the present invention also provides a kind of automobile fire alarm method, such as Fig. 5 institutes

The embodiment of the present invention is crossed, can be transmitted fire signal by rigid line after there is fire behavior and car body controller failure
To car-mounted terminal, to realize remote alarms.
In the embodiment of the present invention, specifically remote alarms process is as follows：
If vehicle is in static, sets up defences and (the possibility situation of the state is that vehicle is set up defences, vehicle in the state of interior someone
Inside leave child or old man), fire master controller receives fire signal, then lights hydropac lamp or/and driving report
Alert loudspeaker, by the fire signal by LIN bus transfers to car body controller；So that car body controller carries out all car doors
Solution is anti-and unlocks, and pass through CAN bus and communicate with car terminal, so as to carry out remote alarms to car owner, while is sent out to server-side
Send information of vehicles and vehicle real-time position information.
If vehicle be in it is static, set up defences and car nobody in the state of (the possibility situation of the state is that car owner is stopped and locked
Vehicle leaves), fire master controller receives fire signal, then lights hydropac lamp or/and driving alarming horn, and by institute
Fire signal is stated by LIN bus transfers to car body controller；So that car body controller is led to by CAN bus and car terminal
Letter so as to carry out remote alarms to car owner, while sends information of vehicles and vehicle real-time position information to server-side.
If vehicle be in static, anti-and interior someone of solution in the state of (the possibility situation of the state is, vehicle have car owner or
Person other people stop rest), fire master controller receives fire signal, then lights hydropac lamp or/and driving alarm loudspeaker
, fire master controller receives fire signal, then hydropac lamp or/and driving alarming horn lighted, the fire is believed
Number by LIN bus transfers to car body controller；So that car body controller is unlocked all car doors, and pass through CAN bus
It communicates with car terminal, so as to carry out remote alarms to car owner, while information of vehicles and the real-time position of vehicle is sent to server-side
Confidence ceases.
If vehicle be in static, solution it is anti-and interior in the state of nobody (the possibility situation of the state is, after car owner's parking,
Forget to set up defences, and leave), fire master controller receives fire signal, then lights hydropac lamp or/and driving alarm loudspeaker
, and by the fire signal by LIN bus transfers to car body controller；So that car body controller passes through CAN bus and vehicle
Sub- terminal communication so as to carry out remote alarms to car owner, while sends information of vehicles and vehicle real time position letter to server-side
Breath.
To sum up, by the feedback acknowledgment of above-mentioned network node and alarm strategy, it more can accurately judge vehicle fire
Calamity time of day is realized in vehicle fire, the linkage of multisystem, and so as to fulfill the alarm of vehicle, personnel's escapes, is fiery
The positioning of feelings vehicle and remote status monitoring.
The embodiment of the present invention is described in detail above, specific embodiment used herein carries out the present invention
It illustrates, the explanation of above example is only intended to help to understand the system and method for the present invention；Meanwhile for the one of this field
As technical staff, thought according to the present invention, there will be changes in specific embodiments and applications, to sum up institute
It states, the content of the present specification should not be construed as limiting the invention.
