DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency notification device for automatically reporting a collision accident or the like occurring in a vehicle or the like to a predetermined reception center or the like.

[0002]

2. Description of the Related Art When an accident involving a vehicle such as an automobile occurs, a driver or a passenger of the vehicle usually informs the police or emergency by telephone communication. In recent years, in order to reduce the reporting time, various systems for automatically reporting the occurrence of an accident to a preset reception center have been considered.

In this case, the use of the existing telephone network is economically advantageous in terms of early spread. On the other hand, the existing system cannot be changed so as not to affect other communications.

[0004] In the above-described automatic notification, the reception center is often informed of the situation using standard information recorded in advance on the transmission side. However, more detailed information is often required, and information collection from the accident party is often required.

Conventionally, when data communication is performed using a mobile telephone device such as a portable telephone, when switching from data communication to voice communication, the line must be disconnected once or
Alternatively, it is necessary to wait until the mobile telephone terminal detects disconnection of the data carrier and switches to voice communication.

[0006]

FIG. 5 is a flowchart showing the flow of processing in such a conventional technique. In the example shown in FIG. 5, after determining that the final data has been transmitted (arrow A), the mobile telephone terminal enters a standby state.

During this time, the reception center determines that the data is the last data, and then the data carrier transmitted from the reception center is cut off. When this is detected on the mobile telephone terminal side (arrow B), switching to the voice communication mode is performed.

As described above, in the conventional technique, there is a waiting time. For this reason, there has been a drawback that the time required for the report is prolonged even in the case of an emergency report in which it is necessary to notify the situation as soon as possible.

The present invention has been made under such a background, and is capable of promptly reporting a collision accident or the like occurring in a vehicle or the like to a predetermined reception center or the like, and enabling voice communication immediately after the report. The purpose of the present invention is to provide an emergency call device .

[0026]

As described above, according to the present invention, when the shock detection means detects a shock, the mobile telephone terminal connected to the reception center and the communication line via the base station and the communication line network is set to the data mode. Then, the transmission of the unique identification data and the environment data is started, the end code is transmitted after the transmission of the unique identification data and the environment data, and the mobile phone terminal is switched to the voice mode after the reception center confirms the reception of the end code. Alternatively, when the shock detecting means detects the shock, the base station and the mobile telephone terminal connected to the communication line with the reception center via the public telephone network are set to the data mode and the transmission of the unique identification data and the environmental data is started. After the transmission of the unique identification data and the environment data, the end code is transmitted, and after the reception center confirms the reception of the end code, the mobile telephone terminal is switched to the voice mode. Further, it is repeatedly monitored whether or not the shock detecting means detects a shock. If the shock detecting means does not detect a shock, environmental data given from outside is sequentially read and stored in the storage means. Then, environmental data is given from vehicle speed detecting means for detecting vehicle speed data and braking detecting means for detecting vehicle braking data, and the impact detecting means is attached to the vehicle. An effect is obtained that an emergency notification device that can promptly notify a reception center or the like and perform voice communication immediately after the notification can be realized.
