Abstract

PROBLEM TO BE SOLVED: To provide an emergency reporting information transmitting method which realizes the efficiency of data communication by ordering transmission priority to transmission data to a center from a vehicle undergoing an accident in a vehicle emergency reporting system. SOLUTION: An emergency reporting device 5 sends group 1 data to a center device 16. The device 16 extracts map data from a map database 13 and performs map display processing. Next, group 2 data is transmitted. In the case retry processing 2 occurs in transmission processing of the group 2 data and retry over occurs in the retry processing, data communication is interrupted and switched to voice communication. Since the group 1 data with high priority is first transmitted, this transmitting method for emergency reporting information prevents such shortage of detail information as in the conventional transmitting method of emergency reporting information in asking an emergency vehicle to be dispatched. In the case the device 16 requests to further acquire detail information, emergency information acquisition processing is executed in the device 16, and an acquisition request for the group 2 data is transmitted to the device 5.

And an emergency notification device for executing the data communication.

[0010]

In order to solve the above-mentioned problems, according to the present invention, an emergency notification device mounted on an accident vehicle includes a GPS, a gyro, a vehicle speed sensor, a collision sensor, a public cellular phone (radio device). ), And the emergency notification device assigns transmission priorities to information transmitted from various vehicles to the center, such as position information, emergency call trigger information, vehicle identification information, vehicle status information, and driver information, and transmits the information in blocks. Then, if block transmission fails, the number of transmission retries is changed based on the transmission priority.

Also, blocks (information) that could not be transmitted
Is configured so that information can be obtained from the center after a voice conversation with the center operator, so that information with a high transmission priority can be transmitted in a short time, and information with a low transmission priority can be transmitted during data transmission. When a retry of data communication occurs due to deterioration of network line quality or the like, data communication is interrupted, and it is possible to quickly shift to voice communication. In addition, if information that has not been transmitted to the center after the voice call with the center operator is also required, the center can acquire the information.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic configuration of the emergency notification system, and FIG. 2 shows a schematic configuration of the emergency notification device. In FIGS. 1 and 2, when an accident such as a vehicle collision occurs, an emergency notification device 5 mounted on the accident vehicle 1 automatically notifies the emergency center 2 of the vehicle emergency information, until the emergency vehicle 4 arrives at the accident site. The time has been reduced so that injured people can be rescued and rescued more quickly.

That is, when the vehicle encounters an accident, the collision detection unit 12 operates, and the operation of the control unit 7 causes the vehicle position data (GPS reception unit 8, gyro 10, The vehicle speed pulse detector 11 and the like are automatically transmitted to the emergency center 2 via a public telephone (wireless device) 6, and the emergency center 2 confirms the position of the accident vehicle based on this data, and Request the dispatch of.

A conventional method for transmitting emergency call information in this case will be described with reference to FIG. In FIG. 3, the emergency report information to be transmitted is divided into packets and transmitted without prioritizing the transmission when transmitting data. That is, first, the packet 1 is transmitted from the emergency notification device 5 to the center device 16.
Sent to Then, the center device 16 extracts map data from the map database 13 and performs a map display process. When the retry process occurs in the transmission process of the packet 1, the retry process is performed.

Next, packet 2 is transmitted. A retry process occurs in the transmission process of this packet 2,
If a retry over occurs during the retry processing, the data communication is terminated and switched to the voice communication. Although it is possible to talk with the occupant of the accident vehicle by voice communication, detailed data such as automatically transmitted sensor information cannot be transmitted to the center device 16 by voice communication.

Therefore, in the conventional method for transmitting emergency call information, a request for dispatch of an emergency vehicle is made without transmitting detailed information to the center device 16, so that there is a problem that appropriate emergency and rescue activities cannot be performed.

In view of the above, the present invention proposes a method for transmitting emergency notification information that enables prompt emergency rescue and rescue activities. FIG. 4 shows a method for transmitting emergency notification information according to the embodiment of the present invention. In FIG. 4, the emergency notification information to be transmitted is subjected to transmission priority classification at the time of data transmission, and high-priority group 1 data is transmitted first. That is, the group 1 data is sent from the emergency notification device 5 to the center device 16. Then, the center device 16 extracts map data from the map database 13 and performs a map display process. When retry processing occurs in the transmission processing of group 1 data, retry processing 1 is performed.

Next, transmission of the next higher priority group 2 data is performed. If retry processing 2 occurs in the transmission processing of this group 2 data, and retry over occurs during the retry processing, data communication is interrupted and switched to voice communication. Although it is possible to have a conversation with the occupant of the accident vehicle by voice communication, detailed data such as sensor information automatically transmitted cannot be transmitted to the center device 16 by voice communication.

However, in the method for transmitting emergency call information according to the present invention, since the high priority group 1 data is transmitted first, the detailed information as in the conventional method for transmitting emergency call information at the request to dispatch an emergency vehicle is given. If the center device 16 requests to acquire more detailed information, the center device 16 performs an emergency information acquisition process and transmits a group 2 data acquisition request to the emergency notification device 5. Is done. Accordingly, the group device 2 data is transmitted, so that the center device 16 can acquire more detailed data. This data can be acquired and the information display process can be performed again, based on which the detailed information is notified to the emergency vehicle, and more appropriate rescue activities can be performed.
