To this end, the accident information collecting apparatus 210 may include a microphone and a speaker for voice input / output, and may include a camera and a display to enable video input / output.

The emergency recovery system server 220 receives the minimum accident information generated by the accident information generation apparatus 100 to determine whether or not an accident has occurred, and performs a function of requesting a rescue organization for a structure, if necessary.

Here, the emergency rescue system server 220 may be configured with a PSAP (Public Safety Answering Point) and a Proxy PSAP (PSAP) function. The PSAP communicates with the driver / passenger to carry out the final accident judgment and perform the function of requesting the rescue organization to go to the rescue. The proxy PSAP receives the minimum incident information and performs automatic voice guidance to the driver / passenger using the automated function to determine whether or not an accident has occurred. If it is estimated that an accident is required, the minimum PSID received is transmitted to the PSAP , You can connect the connected call to the PSAP.

Accordingly, by reconstructing the accident information collected from the various accident information collecting apparatuses into a predetermined structure and generating the minimum accident information, it is possible to solve the compatibility problem and the data unity problem, and to judge whether an accident has occurred or not.

Referring to FIG. 4, the MSD 40 includes version information (msdVersion, 300) of minimum accident information, basic information (msdStructure, 400) as essential elements, and additional information (additionalData, 500) do.

The version information 300 of the minimum accident information is defined to be able to interpret the minimum accident information in the emergency recovery system server (see 220 in FIG. 1). This indicates the version value of the minimum accident information. Depending on the type of the data structure, it can have a value of 1 byte (Integer) sequentially increasing from 1 to 255.

The basic information 400 of the minimum accident information is a set of information that must be included in the minimum accident information when the apparatus for generating minimum accident information (see 100 in FIG. 1) performs normal operation.

Table 1 below shows data types, order and size of data included in basic information of minimum accident information according to an embodiment of the present invention.

3 bits

Referring to Table 1, the first data of the basic information is a messageIdentifier (401) indicating the number of retransmission messages of the minimum-accident information at the time of an accident judgment, and is a 1-byte integer type having a value from 1 to 255 have.

For example, the message sequence number 401 of the minimum accident information transmitted first at the time of occurrence of an accident has a value of 1, and when an application layer ACK (acknowledgment) is not received from the emergency rescue system server (see 220 in FIG. 1) Increase the message sequence number by 1 for each second to retransmit the minimum incident information. If the message sequence number exceeds 255, it is initialized to 1 and retransmitted. If an additional event occurs, the minimum event information value is updated and the message sequence number 401 is initialized to a value of 1 again.

The second data of the basic information is a timestamp (402) indicating the time at which the accident information collecting device (see 210 in FIG. 1) judged the accident, and can have a value of 0 to 4294967295 as an integer of 4 bytes.

The time stamp 402 follows the reference time value of Coordinated Universal Time (UTC), which increases in units of one second from 0:00:00 on January 1, 1970. Korea Standard Time (KST) can be converted through the calculation of +09 time based on UTC. In the emergency recovery system server (see 220 in FIG. 1), the accident time of the minimum accident information received is compared to identify the same accident . If time information can not be acquired, the time stamp 402 can be set to zero.

The third data of the basic information is a control type (controlType, 403) and can have a boolean sequence of 3 bits.

[Water Code 1]

controlType :: = SEQUENCE {

automaticActivation BOOLEAN DEFAULT FALSE,

testCall BOOLEAN DEFAULT FALSE,

positionTrusted BOOLEAN DEFAULT FALSE,

cancelRequest BOOLEAN DEFAULT FALSE

}

In addition, the emergency salvage service test 403b has a logical value of false when the minimum accident information is transmitted for the purpose of emergency rescue service test, and a false value when it is transmitted by automatic algorithm based on the accident judgment. In addition, the vehicle location information trust 403c is true when the location information is acquired through the Global Navigation Satellite System (GNSS), and is false when the location information is acquired in a different manner. In addition, the cancellation of the accident report 403d is true if the accident report is canceled automatically or by the driver / passenger, otherwise it has a logical value of false.

The fourth data of the basic information is vehicle type (vehicleType, 404) and may have an enumerated data type of 5 bits. This can be expressed as a 5 digit binary number.
