# Automatic notification of vehicle accident

Alexander Ioffe

Unfortunately, very often in a car accident victim is not just medical care. This comes from the fact that the victims themselves are not able to call an ambulance. And the passing pedestrians and drivers hope to each other. Moreover, it happens that the accident occur in a deserted place. Already exist system automatically sends a signal for help with the accident, triggered by means of safety equipment or acceleration. They use the built-in GPS and mobile phone. But often calls are false. Enough to brake sharply or only slightly to damage the car case without prejudice to sitting in people, and from the Center of the Help the car will already rush off, subjecting also to some risk of participants of traffic, not to mention the cost of such trip and derivation of forces. Presented in this project system provides the right located inside the car people decide how serious the accident occurred and whether it will do. At the same time, care is delayed by only a few tens of seconds. Recently, already began to appear such systems, so this example: http://www.wired.co.uk/news/archive/2011-09/05/ford-ifa-connected-cars. I just think that the proposed system in this project may be more convenient to use (it is better to not have to use it!).

AUTOMATIC NOTIFICATION OF VEHICLE ACCIDENT

FOREWORD Unfortunately, very often in a car accident victim is not just medical care. This comes from the fact that the victims themselves are not able to call an ambulance. And the passing pedestrians and drivers hope to each other. Moreover, it happens that the accident occur in a deserted place. Already exist system automatically sends a signal for help with the accident, triggered by means of safety equipment or acceleration. They use the built-in GPS and mobile phone. But often calls are false. Enough to brake sharply or only slightly to damage the car case without prejudice to sitting in people, and from the Center of the Help the car will already rush off, subjecting also to some risk of participants of traffic, not to mention the cost of such trip and derivation of forces. Presented in this project system provides the right located inside the car people decide how serious the accident occurred and whether it will do. At the same time, care is delayed by only a few tens of seconds. Recently, already began to appear such systems, so this example: http://www.wired.co.uk/news/archive/2011-09/05/ford-ifa-connected-cars. I just think that the proposed system in this project may be more convenient to use (it is better to not have to use it!).

OPERATION OF THE SYSTEM


In the event of an emergency means of safety equipment, such as radar, or automatic activation (eg acceleration) of at least one of the safeties transport, say the air bag inflates, fires a trigger that starts a timer for a few tens of seconds, and if you do not disable the timer in case false alarm (accident not occurred) special switch, the system automatically, using mobile phone, send an informational message to Center for Aid that the accident occurred, specifying the location coordinates of the vehicle, combined with GPS, which must necessarily be equipped the car. At the switched-on timer to inform passengers and the driver on his work, voice messages with time countdown until a parcel of a signal of the help join. In the power of people or without waiting for the end of operation of the timer to send a signal of the help turn of the special switch if they after accident are able to make it, or to cancel a signal parcel. It is better to do the switch rotary that there was no casual pressing of the button from a push. Electronic part of system and devices it is better to arrange in the center of salon of the car (less damage from blow at accident) in a special protecting rigid box (outside this box has to have a soft covering that passengers didn't suffer having hit about it, and inside shock-absorbing laying for protection of devices and electronics). The rotary switch has to be in convenient reach of all people who are in the car. For example, as it is shown in drawing. Having turned the switch handle to the full to a “red field” the person sends a signal of the help to Center for Aid immediately. That has to be confirmed with a voice message of system. Having turned the handle moving after operation of the timer automatically to a “red field”, to the full in other direction, and having established it on "green field", the person cancels a signal parcel that also is confirmed by a voice message of system. It makes sense to avoid sending a signal for help from carelessness or hooliganism passengers when they turn the handle for no reason on a “red field”, to block such opportunity (operations only from turn on a “red field”) without preliminary operation of the trigger as conditions. The toggle-switch of blocking is recommended to arrange to the left of the driver (out of reach of passengers). If accident happened, and any of devices didn't work, including the trigger, at people in salon nevertheless opportunity to call "Ambulance" via the presented device will remain. They will have to click the toggle-switch of an unblocking of a casual message of a signal and to turn the switch handle on a “red field”. In the same way it will be possible to get help for people affected by the accident occurred nearby.
