Abstract

The disaster information system according to the invention includes a disaster noticing server and a disaster reporting terminal. The disaster noticing server calculates the expected time of arrival at which the natural disaster will arrive at the current location of the disaster reporting terminal, and transmits the calculated expected time of arrival to the disaster reporting terminal. The disaster reporting terminal, when it receives the expected time of arrival from the disaster noticing server, acquires the current time measured at the disaster reporting terminal, and calculates the time remaining until the natural disaster will arrive at the disaster reporting terminal from the expected time of arrival and the current time.

Claims

1. A system for providing a notice of a disaster comprising:

at least one terminal;

a server providing information related to said disaster for said terminal;

wherein said server calculates an expected time of arrival of said disaster at said terminal in case said disaster happens, and transmits said expected time to said terminal, and

wherein said terminal measures the current time, and calculates the time remaining until said disaster arrives at said terminal, based on said expected time and said current time.

2. The system according to claim 1,

wherein said server transmits a checking time of the accuracy of the said current time to said terminal,

wherein said terminal receives said checking time and calculates a difference between said checking time and said current time, and

wherein said terminal calculates said time remaining, based on said expected time and said checking time if the difference exceeds a threshold, and otherwise said terminal calculates said time remaining based on said expected time and said current time.

3. The system according to claim 1, wherein said terminal displays said time remaining.

4. The system according to claim 1,

wherein said server calculates an impact of said disaster against a location of said terminal and transmits said expected time and said impact to said terminal,

wherein said terminal displays said time remaining and said impact.

14. The system according to claim 2, wherein said terminal displays said time remaining.

15. The system according to claim 2,

wherein said server calculates an impact of said disaster against a location of said terminal and transmits said expected time and said impact to said terminal,

wherein said terminal displays said time remaining and said impact.

5. A server providing information related to a disaster comprising:

a calculating unit that calculates an expected time of arrival of said disaster at a terminal in case said disaster happens;

a transmitting unit that transmits said expected time to said terminal;

wherein said transmitting unit transmits a checking time to said terminal, wherein said terminal calculates the time remaining until said disaster arrives at the said terminal based on said expected time and the current time, wherein said terminal checks the accuracy of said current time based on said checking time.

6. A terminal receiving information related to a disaster comprising:

a receiving unit that receives an expected time of arrival of said disaster at said terminal;

a measuring unit that measures the current time; and

a calculating unit that calculates time remaining until said disaster arrives at said terminal based on said current time and said expected time.

7. The terminal according to claim 6, wherein said receiving unit receives a checking time of the accuracy of said current time,

wherein said calculating unit calculates a difference between said checking time and said current time,

wherein said calculating unit calculates said time remaining, based on said expected time and said checking time if the difference exceeds a threshold,

and otherwise said calculating unit calculates said time remaining based on said expected time and said current time.

8. The terminal according to claim 6, further comprising:

a displaying unit that displays said time remaining.

16. The terminal according to claim 7, further comprising:

a displaying unit that displays said time remaining.

9. A method for providing a notice of a disaster from a server to at least one terminal comprising:

in a server, calculating an expected time of arrival of said disaster at a terminal in case said disaster happens;

transmitting said expected time to said terminal;

in said terminal, measuring the current time; and

calculating the time remaining until said disaster arrives at said terminal based on said expected time and said current time.

10. A method for providing information related to a disaster from a server to at least one terminal comprising:

in a server, calculating an expected time of arrival of said disaster at said terminal in case said disaster happens;

transmitting said expected time to said terminal;

transmitting a checking time to said terminal;

in said terminal, measuring the current time;

checking the accuracy of the current time using said checking time; and

calculating the time remaining until said disaster arrives at said terminal based on said expected time and said current time.

11. A computer readable medium embodying a program, said program causing a server to perform a method for providing a notice of a disaster from said server to at least one terminal, said method comprising:

calculating an expected time of arrival of said disaster at a terminal in case said disaster happens;

transmitting said expected time to said terminal; and

transmitting a checking time to said terminal,

wherein said terminal calculates the time remaining until said disaster arrives at the said terminal based on said expected time and the current time,

wherein said terminal checks the accuracy of said current time based on said checking time.

12. A method for controlling a terminal, comprising:

receiving information related to a disaster;

measuring the current time; and

calculating the time remaining until said disaster arrives at said terminal based on said expected time and said current time.

13. A computer readable medium embodying a program, said program causing a terminal to perform a method, said method comprising:

receiving information related to a disaster;

measuring the current time; and

calculating the time remaining until said disaster arrives at said terminal based on said expected time and said current time.
