[0016]
FIG. 3 is a diagram illustrating a process from occurrence of an incident to notification to a corresponding department. When an emergency occurs, the caller operates the keyboard unit 105 and the camera unit 104 of the mobile phone 1 to display a sign that can identify the site, for example, an address display sign attached to a telephone pole, or a famous sign. A sign representing a name of a identifiable building, public property, or the like is acquired as image information. Further, when the emergency target is a car, an image of a license plate of the car is obtained (step S1).
[0017]
Further, the mobile phone 1 generates current position information by comparing the electric field strengths from the plurality of mobile network base stations 2 (step S2).
[0018]
The acquired information is stored in a memory in the mobile phone 1. Next, a call is made to the telephone number of the registered emergency contact (management server 501), and the contents of the case are notified by voice. At this time, the stored image information such as the address display sign is transmitted. Here, when the mobile phone 1 is used as a mail function, it can be transmitted using a mail address as an emergency contact, and the voice information or the image information can be transmitted as an attached file (steps 3 and 4).
[0019]
The management server 501 includes a database 301 storing keywords for voice recognition, and voice recognition means for recognizing the voice based on the database. Further, it may include an address dictionary or a database 302 storing contractor information, and may include image recognition means for recognizing the image based on the dictionary or the database. In addition, the management server includes an analysis unit that analyzes the recognition result of the voice recognition unit or the image recognition unit, and sends the emergency notification to an optimal related department based on the analysis result (step S5).
[0020]
FIG. 4 is a diagram illustrating a distribution process for distributing the emergency information transmitted from the mobile phone 1 to the relevant department.
[0021]
When the management server 501 of the management headquarter 5 detects an incoming call of the transmission data from the mobile phone 1, it connects the line (step S11). Next, the management server responds with an automatic reception announcement (for example, please tell us the case details) (step S12). Next, the management server extracts voice information representing the content of the case from the caller, and recognizes the emergency communication content by voice recognition. At the time of this voice recognition, the recognition accuracy can be improved by referring to the voice recognition database 301 in which the recognition keywords are registered, as compared with the case where general terms are recognized by voice. The validity of the recognition result can be analyzed by comparing the recognition result with, for example, the current position information acquired by comparing the electric field strength (steps S13 and S14). Next, recognition and collation of image information and position information described later are performed, and the recognition result is edited as, for example, additional information of a mail (step S15).
[0022]
At the time of voice recognition, the keyword is collated with the keyword for each accident type stored in the voice recognition database 301. That is, as a result of the voice recognition, if the recognized keyword includes “traffic accident”, a mail for the insurance center terminal 601 is created and transmitted (steps S16 and S17).
[0023]
Also, as a result of the voice recognition, when the recognized keyword includes, for example, “fire”, a mail for the fire department terminal 701 is created and transmitted (steps S18, S19).
[0024]
If the recognized keywords include, for example, "disease" or "hospital" as a result of the voice recognition, a mail for the hospital terminal 801 is created and transmitted (steps S20 and S21).
[0025]
If the recognized keywords include, for example, "crime" and "case" as a result of the voice recognition, a mail for the police station terminal 901 is created and transmitted (steps S22 and S23). If the recognition is not possible, the operator is called (step 24).
[0026]
FIG. 5 is a diagram for explaining the recognition processing of the image information and the position information in step S15. When the image information and the position information are received, the image information is extracted from the received information (step S31). If the extracted image information includes the registration number of the vehicle, the corresponding registration number is image-recognized. Next, the database 302 storing the registration number of the vehicle is searched based on the recognition result, and the validity of the recognition result is analyzed and verified (steps 32 and 33).
[0027]
When an address display sign is included in the extracted image information, the address display sign is image-recognized. Next, the database 303 storing the address data is searched based on the recognition result, and the validity of the recognition result is analyzed and verified (steps S35 and S36).
Next, position information is extracted from the received image information and position information (step S34). Next, the extracted position information is collated with the position information recognized in step S35 (step S37). Thereby, the validity of the recognition result can be further verified. If there is a large difference between the position information recognized in steps 35 and 34, the position information obtained in step 34 (position information obtained from the mobile network) may be given priority.
[0028]
FIG. 6 is a diagram showing the format of the speech recognition database 301. As shown in the figure, a keyword corresponding to each accident type is registered, and a relevant pertinent department corresponding to the keyword, its telephone number (TEL), and mail address are registered. For example, in FIG. 4, when "fire" is recognized as a keyword, the related department is "fire department", and the corresponding telephone number and mail address are stored.
[0029]
FIG. 7 shows the format of the vehicle registration number database 302. For example, data such as a holder name, an address, a telephone number (TEL), a mobile telephone number (TEL), an insurance contract number, a past use history, and an insurance card number are stored using a vehicle registration number as a key.
[0030]
FIG. 8 is a diagram showing a format example of the address database 303. The database 303 stores address data of municipalities in each prefecture. By collating the address data recognized in the step 35 with the address data stored in the address database, it is possible to identify the accident occurrence location with high recognition accuracy.
[0031]
FIG. 9 is a diagram illustrating an example of an outgoing mail transmitted from the management server 501 of the management headquarters 5 to the fire department terminal 701 of the fire department 7. The content of the occurrence of the incident is the character "fire" recognized by voice, and the "address" recognized by the image is displayed at the place of occurrence. Furthermore, it is also possible to attach image information and a sound file sent for reference.
[0032]
FIG. 10 is a diagram illustrating an example of an outgoing mail transmitted from the management server 501 to the insurance center terminal 601 of the automobile insurance center 6. In this example, the content of the occurrence of the incident recognized by voice “accident”, the address of the occurrence location obtained by the image recognition, and the vehicle registration number are displayed.
[0033]
Note that the image information and position information recognition processing or the voice recognition processing shown in FIG. 5 is executed by the management server 501 and individually in the insurance center terminal 601, the fire station terminal 701, the hospital terminal 801 and the police station terminal 901. May be executed.
[0034]
In the above description, the insurance center 6, the fire department 7, the hospital 8, and the police department 9 have been described as report destinations. However, it is also possible to report to a security company or a security company. In addition, although a traffic accident, a fire, and the like are assumed as emergency situations, the present invention can be applied to other non-emergency cases. Further, a PDA (Personal Digital Assistant) or the like can be used outside the mobile phone as a device for reporting occurrence of an emergency emergency.
[0035]
As a method of finding the position information, a method of finding the position by the electric field strength from a plurality of mobile network base stations has been exemplified. However, the position is found by a mobile terminal equipped with a GPS (Global Positioning System) function, and a message from the mobile terminal is used. A method of embedding the position in the notification and notifying can be applied.
[0036]
In this example, voice and image recognition are performed in the management server 501. However, only minimum voice and image recognition necessary for separation are performed, and the remaining detailed recognition (address, location, car registration number, etc.) is performed. This may be performed at each of the terminals 601 to 901.
[0037]
