| Heavy Rain Monitoring System for Populated Areas |
| These systems, which provide automated monitoring
of rainfall intensity, are specifically designed
for timely, reliable operation in an urban
environment. AMeDAS data released by the
Japanese Meterological Agency is a measurement
of total rainfall for the previous hour,
but that one-hour time lag can result in
a corresponding lag in preventing disasters
resulting from flooding. With a rooftop-mounted digital rain gauge, Komatsu Factory Co.'s systems are configured to provide timely information right where it's needed. Rainfall intensity (10-minute precipitation) is accurately monitored around the clock, and the latest information and any pertinent alarm data are displayed on-screen. Precipitation data measured by the rain gauge is converted into digital format and automatically stored by a data logger. The data logger and a personal computer are directly connected using RS232C format. Rainfall intensity data is transmitted every 10 minutes from the data logger to the PC, which collates and records data and triggers an alert or alarm when necessary. Monitoring screen displays are also automatically updated with each transfer of data. |
