Era GLONASS is approaching

According to resolution the government "On creation of automated system of emergency response in case of accidents ERA-GLONASS" in Russia is expected to deploy the system, designed to reduce the consequences of accidents by increasing the speed of response of emergency services.

rescue Service to the rescue

Based on European statistics, the average response time in accidents, in the modern metropolis, is more than 20 minutes. For Russia — this time, maybe a few more.


Components can vary depending on the severity of the incident, local conditions and availability of communication, but in any case, every minute can have critical consequences.

Rule of the Golden hour

In emergency medicine, time is from several minutes to several hours, during which most likely can save lives, called the "Golden hour".

On the chart, in the temporal chronology, depicts the three most common causes of death in an accident:

the

the
• cardiac arrest
the
• respiratory arrest
the
• extensive bleeding

As you can see, minutes play a big role in saving lives.

Description

To implement the system in the vehicle must be equipped with an electronic unit with a GLONASS/GPS chip, which at the time of the accident will have to pass through the channels of cellular networks: coordinates, information about the accident and to establish voice communication between emergency response team and the car.

General scheme looks like this:

the
1. In the time of the accident, through the CAN bus of the vehicle electronic control unit receives information about the accident (airbag deployment, accelerometer data, etc.) and General information about the car (VIN code and a set of user data).
the
2. Block determined by the coordinates of the terrain and takes place a voice call to the emergency center (PSAP). In the first few milliseconds the voice channel will transmit a minimum set of data (MSD) containing: the coordinates of the vehicle information read by the unit from the onboard computer and/or accelerometer. Then installed Handsfree between the car and the emergency operator. Even if the participant of road accident trapped in the wrecked car, he will be able to speak with the operator on speakerphone.
the
3. In the center of the response data konsolidiruyutsya and supplemented according to the available databases, and then automatically transmitted to emergency services.
the
4. Emergency services have all the necessary information to quickly respond to the incident.

Guaranteed communication channel

The use of the channel 112, to transmit information, will provide the opportunity to communicate regardless of the coating operator specific.
For guaranteed transfer data using a voice channel, as we know with the highest priority in the cellular network. For the transmission of MSD provides specialized algorithms depending on the quality of communication to use a different transmission speed.
The unit will retry to transmit the MSD at different speeds until receipt of notification to accept from the server.
Possible options for the transfer MSD in Push mode and Pull. To request data package, you can use Pull mode and the unit will re-transmit information within one and the same voice session.
MSD involves transferring the required parameters, such as: geographic coordinates, the accident parameters, the vehicle parameters and user parameters.

responsive

After you run the automatic response, based on the experience of European countries, you can expect to reduce response time by 40%.

Era GLONASS is approaching

The wait is not long, the time of start of the program — January 1, 2014.
Since when 100% of all new cars will necessarily be equipped with units for participation in the program is an open question.
Also, discussed the need for inclusion in the programme of car aftermarket, and auto imported from abroad.
