Background technology
Major traffic accidents rescue promptly and accurately is the great means of saving life, reducing the loss.Countries in the world are all in the relevant technology of research and development, and developed country has many research and use in this respect.Wherein France's sign Citreen is that first uses the automobile of emergency aid system against traffic accidents in the world, has now used on the small passenger car of various models.
1, France's sign Citreen automobile emergency calling system.This emergencycallboxsystem is a kind of three level security systems, can start by following several modes: the one, and automatic startup, system automatic activation after the air bag of the vehicle that meets accident is opened.The 2nd, manually boot, pin the SOS button and do not loose one's grip, kept at least two seconds, if the driver of the vehicle that meets accident can also move, be responsible for touching the button by him, or touched the button in the car of this system is housed by the eyewitness of major accident together.After emergencycallboxsystem started, the GSM phone on control stand sent the SMS signal.This information comprises vehicle model, its information such as geographic position and telephone number accurately.After having grasped the information of being transmitted by the SMS signal, the telephonist of rescue center that helps each other starts to set up audio communication with the vehicle that meets accident and contacts, and can on-the-spot situation be judged thus, comprises the order of severity of traffic accident, number of the wounded etc.The emergency physician stood ready in 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 personnels such as fire fighter, police, doctor will be sent to the scene of the accident
This is a kind of mixing technology of seeking help, and initiatively rescue depends on the action of air bag, has limitation; Passive rescue depends on how long can be found by the eyewitness, rescue time is long.
2, pan-European vehicle emergency call system eCall.Use this system, car manufactures must be installed SIM card and GPS module on the truck-mounted computer of vehicle, and the flip flop equipment of eCall system is connected with air bag sensor.If run into major accident, the eCall system can be automatically by the gps coordinate of vehicle, time of casualty, accident vehicle license plate number, even be that the information such as passengers quantity of securing band send to the general emergency telephone number of European Countries 112 in vehicle.The staff of call center can send rescue group or breakdown gang to rush for the scene of the accident according to these information, or sets up voice and be connected with the people in vehicle.
This system is similar with the emergencycallboxsystem of sign Citreen, depends on the action of vehicle airbag, can not cause warning if air bag is not opened, and does not have the vehicle of equipment safety air bag to 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.After having an accident, press the accident rescue button by driver or eyewitness and carry out long-range calling for help.
This is a kind of passive rescue system, if the driver goes into a coma, do not found in time rescues slowly.
4, based on the automatic alarm system of acceleration transducer or crash sensor.The research and comparison of this respect is many, and majority is present in all kinds of documents.Such as " applied research of onboard wireless location technology 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-used automatic alarming system based on MEMS accelerometer " (Source Chinese Journal of Sensors and Actuators887-922009), " Traffic accident informing method for vehicle i.e.car, involves outputting vehicle traveling information from global positioning system navigation unit to accident center server by using mobile communication terminal i.e.cellular phone " (KR2008052310-A), " Vehicle automatic alarming and navigation system " (Source Microcomputer Information210-11,2422008), " ACN (Automatic Collision Notification)--reducing fatalities in traffic accidents by automated accident reporting " (Source Kongressbd Dtsch Ges Chir Kongr119546-82002), " Effecting alarm at vehicle in traffic accidentusing crash sensor, GPS receiver, system control and telephone to determine gravity and position of vehicle accident and automatically transmitting alarm signal contg.relevant data " (DE4421960-A, DE4421960-A1, DE4421960-C2)
The related technology of above document based on upper be all to using acceleration change as unique identification parameter, due to impacts such as acceleration sensor or crash sensor self precision and Vehicular vibration, impact, position of collisions, failing to report and reporting by mistake of system is more serious.
