Abstract

This invention provides a disaster prevention system capable of taking an effective measure against a flood disaster. According to one embodiment, a disaster prevention system comprises a weather prediction unit configured to calculate a predicted rainfall in a region based on rainfall information necessary for protecting the region from a flood; an analysis unit configured to determine, based on the predicted rainfall calculated by the weather prediction unit, whether a flood can occur in the region; and a control unit configured to control to close a water stop gate provided in the region to protect the region from the flood if the analysis unit determines that the flood can occur in the region.

First claim

What is claimed is:

1 . A disaster prevention system comprising:
a weather prediction unit configured to calculate a predicted rainfall in a region based on rainfall information necessary for protecting the region from a flood; an analysis unit configured to determine, based on the predicted rainfall calculated by the weather prediction unit, whether a flood can occur in the region; and a control unit configured to control to close a water stop gate provided in the region to protect the region from the flood if the analysis unit determines that the flood can occur in the region.

2 . The disaster prevention system according to claim 1 , wherein the rainfall information is observed by a weather radar.

3 . The disaster prevention system according to claim 1 , wherein the region is a region partially surrounded by one of a wall and the water stop gate configured to protect the region from the flood.

4 . The disaster prevention system according to claim 1 , wherein the analysis unit determines whether the flood can occur in the region, based on water level information of a river in the region as well.

5 . The disaster prevention system according to claim 1 , wherein the analysis unit determines whether the flood can occur in the region, based on flow rate information of sewage as well.

6 . The disaster prevention system according to claim 1 , wherein if the analysis unit determines that the flood can occur in the region, the control unit further operates a drain pump provided in the region.

7 . The disaster prevention system according to claim 6 , wherein the drain pump is connected to an uninterrupted power supply placed in the region.

8 . The disaster prevention system according to claim 1 , wherein if the analysis unit determines that the flood can occur in the region, the control unit controls a water stop plate provided at a gateway of a subway in the region.

9 . The disaster prevention system according to claim 1 , wherein if the analysis unit determines that the flood can occur in the region, the control unit controls a water stop plate provided at an entrance of a building in the region.

10 . A disaster prevention system comprising:
a weather prediction unit configured to calculate a predicted rainfall in a region based on rainfall information necessary for protecting the region from a flood; an analysis unit configured to determine, based on the predicted rainfall calculated by the weather prediction unit, whether a flood can occur in the region; and an instruction unit configured to output an instruction to use a water stop plate provided in the region if the analysis unit determines that the flood can occur in the region.

11 . The disaster prevention system according to claim 10 , wherein the rainfall information is observed by a weather radar.

12 . The disaster prevention system according to claim 10 , wherein the region is one of a region partially surrounded by one of a wall and the water stop gate provided at a gateway, a gateway of a subway, and an entrance of a building.

13 . The disaster prevention system according to claim 10 , wherein the analysis unit determines whether the flood can occur in the region, based on water level information of a river in the region as well.

14 . The disaster prevention system according to claim 10 , wherein the analysis unit determines whether the flood can occur in the region, based on flow rate information of sewage as well.

15 . The disaster prevention system according to claim 10 , further comprising a notification unit configured to notify use of the water stop plate based on the instruction by the instruction unit.

16 . The disaster prevention system according to claim 10 , wherein the notification unit notifies using a display device.

17 . A disaster prevention system comprising:
a weather prediction unit configured to calculate a predicted rainfall in a region based on rainfall information necessary for protecting the region from a flood; an analysis unit configured to determine, based on the predicted rainfall calculated by the weather prediction unit, whether a flood can occur in the region; and means for providing an evacuation route to a resident in the region if the analysis unit determines that the flood can occur in the region.

18 . The disaster prevention system according to claim 17 , wherein the rainfall information is observed by a weather radar.

19 . The disaster prevention system according to claim 17 , wherein the means for providing provides a hazard map representing a region where a flood can occur including the evacuation route.

20 . The disaster prevention system according to claim 17 , wherein the evacuation route is an evacuation route at a current time.

21 . The disaster prevention system according to claim 17 , wherein the evacuation route is a predicted evacuation route.
