Disaster Prevention System using Information Techonology

1)在水俣泥石流发生点周围设置防灾无线网络。该网络通过光纤到户（ftth）与Internet相连。2)开发了具有GPS单元的手机定位系统。当它访问服务器时，它返回泥石流的动态危害图。3)为了接收来自日本MLIT的降水雷达数据，在FTTH上安装VPN接入线路。开发了一个Java程序将接收到的数据保存到XML数据库中。4)召开了水俣病及地方政府工作人员答问会。5)通过对过去降雨和泥石流的分析，发现了泥石流发生的临界限制和集水区的集中时间。6)在樱岛火山野尻河安装了泥石流探测机器人。7)在Tarumizu泥石流调查后，我们担心有必要在日本安装我们的系统。

1)Wireless network for disaster privention is installed around the occurrence point of debris flow in Minamata. This network is connected to Internet via FTTH.2)It is developed that the posision of celluar phone with GPS unit is developed. When it access the server, it returns the dynamic hazard map of debris flow.3)To receive the precipitation radar data from MLIT, Japan, a VPN access lline is installed on FTTH. A Java program which save the received data to the XML database was developed.4)Questionary for Minatama and stuffs of local goverments was held.5)Anayzing the past rainfall and debris flows, it is founded that the critical limitation of occurrence of debris flow and the concentration time of the catchment area.6)It is installed that a robot of sencing the debris flows at Nojiri River in Sakurajima Volcano.7)After investiogation of the debris flow at Tarumizu, we concerned that it is nessesary to install our system in Japan.
