Accompanying drawing explanation
Fig. 1 is the structured flowchart of present embodiment automobile collision information detecting/warning system;
Fig. 2 is the FB(flow block) of present embodiment automobile collision information detecting/warning method.
Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by detailed description of the invention.
As shown in Figures 1 and 2, automobile collision information detecting/warning system of the present invention is used for detecting car condition information in real time in vehicle traveling process, once detect that automobile collides and put air bag quick-fried, then this system can detect the situation of collision in time, and collision information is sent to background server in time.
Automobile collision information warning comprises power module, main control module, interface module, wireless communication module and GPS module.Power module provides clean, stable power supply, for circuit provides short-circuit protection, overvoltage protection, under-voltage protection and overcurrent protection etc. for whole system.Interface module is used for the vehicle condition information be connected with automobile bus to obtain automobile.Wireless communication module is for realizing the radio communication with background server.GPS module is for obtaining time of automobile, position, speed information.This vehicle condition information can comprise speed information and inflatable balloon-like state information, the resistance value etc. that this air bag status information can comprise air bag diagnostic code, air bag indicator lamp, gas-bag system have failure-free status information, airbag deployment loop.
Interface module, wireless communication module and GPS module are all connected with this main control module, and this main control module is used for coordinating, controlling each module.
Main control module can comprise memory module and comparison module, and memory module is for storing default vehicle condition information, and this comparison module is for comparing the real-time vehicle condition information of the automobile of collection and default vehicle condition information.This comparison module is also for comparing real time resistance value and the predetermined resistance value in the airbag deployment loop of collection.Certainly, memory module also can be arranged independent of main control module.
Wireless communication module can for GPRS module, 3G module, 4G module or other can realize the module of long distance wireless communication.
Interface module can be the CAN interface module that can communicate to connect with the CAN of automobile.
The working process of this detecting/warning system is as follows:
1) main control module is by CAN interface module, from the vehicle condition information of the CAN real-time sense automobile of automobile, and the default vehicle condition information comparison will stored in the real-time vehicle condition information of collection and memory module.This vehicle condition information can comprise speed information and inflatable balloon-like state information, and this air bag status information can comprise the status information of air bag indicator lamp, gas-bag system has failure-free status information, the resistance value in air bag diagnostic code and airbag deployment loop.Relatively during the speed of a motor vehicle, the real-time speed of a motor vehicle compared with preset vehicle speed, this preset vehicle speed can be a numerical value, also can be a speed range.This speed of a motor vehicle by the CAN collection of automobile, also can be gathered by GPS module.Airbag deployment loop such as chaufeur frontal airbags launches loop.
2) if real-time vehicle condition information is identical with default vehicle condition information, then step 1 is returned); If real-time vehicle condition information is different from default vehicle condition information, then enter step 3).
3) main control module is by CAN interface module, send the instruction of the status information reading gas-bag system to car airbag system, if the real time status information gathered is identical with preset state information, then return step 2), if both are different, then enter step 4).As air bag pops during auto against, then have diagnostic code and produce, what this step read is this diagnostic code, as read diagnostic code, namely represents that the status information of gas-bag system changes.And, by diagnostic code, can know which air bag pops.Such as show diagnostic code B1820, then represent side air bag flip-flop circuit short circuit, namely represent that the air bag of operating seat side has popped.
4) main control module is by CAN interface module, the instruction of the resistance value reading existing " chaufeur frontal airbags launches loop " is sent to gas-bag system, if the resistance value of Real-time Collection is normal, then return step 3), if resistance value is infinitely great, failure judgement necessary being, then enter step 5); This normally refers to that the real time resistance value of collection is identical with predetermined resistance value, and this predetermined resistance value can be a numerical value, also can be a number range.By detection resistance value, then can verify the authenticity of air bag diagnostic code.
5) judgement of necessary being if abovementioned steps breaks down, the information such as place during main control module instruction GPS module acquisition collision and time, are then sent to the background server being located at the departments such as 4S station, insurance company, hospital or traffic police by failure message by wireless communication module.
In present embodiment, the vehicle condition information of Real-time Collection automobile, and compare real-time vehicle condition information and default vehicle condition information, when this compares, need to compare the speed of a motor vehicle and inflatable balloon-like state simultaneously, as neither identical, then then judge which air bag pops according to the diagnostic code of air bag; And the authenticity of diagnostic code is checked according to the resistance value in airbag deployment loop, when after above-mentioned completing, just confirm that automobile collides.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
