Background technology
Major traffic accidents rescue promptly and accurately is the great means saving life, minimizing loss. Countries in the world are all in the technology that research and development is relevant, and developed country has the many research of comparison and use in this respect. Wherein France's mark Citreen is the automobile of first utilization emergency aid system against traffic accidents in the world, now already with on the small passenger car of various models.
1, France's mark Citroen cars emergencycallboxsystem. This emergencycallboxsystem is a kind of three level security systems, it is possible to started by following several ways: one is automatic startup, and after the air bag of the vehicle that meets accident is opened, system activates automatically. Two is manually boot, and pins SOS button and does not loose one's grip, and keeps at least two seconds, if the driver of the vehicle that meets accident can also move, he is responsible for touching the button, or is touched the button in equipped with the car of this system by the witness of major accident together. After emergencycallboxsystem starts, the GSM phone on bench board sends SMS signal. This information includes vehicle model, its information such as geographical position and telephone number accurately. After having grasped the information transmitted by SMS signal, the rescue center operator that helps each other starts to set up audio communication with the vehicle that meets accident and contacts, and it is possible to on-the-spot situation is judged, including the number etc. of the order of severity of traffic accident, the wounded. One emergency physician stood ready for 24 hours can provide medical advice by long-range means in the case of necessary. Under the requirement of the rescue center that helps each other, the rescue personnel such as fire fighter, police, doctor will be sent to the scene of the accident
This is a kind of technology of seeking help that mixes, and active rescue depends on the action of air bag, there is limitation; Passive rescue depends on how long can being found by witness, rescue time is long.
2, pan-European vehicle emergency call system eCall.Using this system, car manufactures must install SIM and GPS module on the car-mounted computer of vehicle, and the triggering device of eCall system is connected with air bag sensor. If running into major accident, the information such as passengers quantity in the gps coordinate of vehicle, time of casualty, accident vehicle license plate number, even vehicle being seat belt automatically can be sent to the general emergency telephone number of European Countries 112 by eCall system. The staff of call center can send rescue group or relief and emergency services to rush for the scene of the accident according to these information, or set up voice with the people in vehicle and be connected.
This system is similar with the emergencycallboxsystem of mark Citreen, depends on the action of vehicle airbag, if air bag is not turned on, can not cause warning, it does not have the vehicle of equipment safety air bag cannot use.
3, the Anji star of General Motors. This is that a kind of cdma network that depends on carries out voice, data communication and gps satellite and positions the system with navigation Service, has the functions such as accident rescue, hospital services, maintenance service. Pressed accident rescue button by driver or witness after having an accident remotely to call for help.
This is a kind of passive rescue system, if driver goes into a coma, do not found in time, rescue is slowly.
4, based on the automatic alarm system of acceleration transducer or crash sensor. The research of this respect is relatively more, and majority is present in all kinds of document. Such as " onboard wireless location technology applied research in freeway incident detection " (Li Chuanzhi; Hu Rufu; He Jie; Hang Wen; Tao Xiangli; China's public safety (general news column), 2008, (Z1), 142-146), " land communications accident automatic detection warning and artificial emergency alarm device " (CN201383219), " vehicle collision automatic alarm system " (CN101556735), " Vehicle-usedautomaticalarmingsystembasedonMEMSaccelerome ter " (SourceChineseJournalofSensorsandActuators887-922009), " Trafficaccidentinformingmethodforvehiclei.e.car, involvesoutputtingvehicletravelinginformationfromglobalp ositioningsystemnavigationunittoaccidentcenterserverbyus ingmobilecommunicationterminali.e.cellularphone " (KR2008052310-A), " Vehicleautomaticalarmingandnavigationsystem " (SourceMicrocomputerInformation210-11,2422008), " ACN (AutomaticCollisionNotification)--reducingfatalitiesintrafficaccidentsbyautomatedaccidentr eporting " (SourceKongressbdDtschGesChirKongr119546-82002), " Effectingalarmatvehicleintrafficaccidentusingcrashsensor, GPSreceiver, systemcontrolandtelephonetodeterminegravityandpositionof vehicleaccidentandautomaticallytransmittingalarmsignalco ntg.relevantdata " (DE4421960-A, DE4421960-A1, DE4421960-C2)
Technology involved by document above based on upper be all using acceleration change as unique identification parameter, owing to acceleration sensor or crash sensor self precision and Vehicular vibration, impact, position of collision etc. affect, system fail to report and to report ratio by mistake more serious.
