2. Description of the Related Art As is well known, landslides, avalanches, floods,
In areas where disasters such as earthquakes and volcanic eruptions are expected to occur, natural disasters are constantly monitored for changes in natural events, and when a danger is imminent, a warning is issued to warn nearby residents, visitors and vehicles. It is necessary to announce.

Conventionally, as a means for responding to such a request, a point where a sign of occurrence of a disaster appears is selected as a monitoring point and a monitoring sensor (for example, a water level gauge, a crack gauge, an inclinometer, a pipe strain gauge, a pipe strain gauge, Tilt meters, load meters, extensometers, etc.) are installed, and when the monitoring signal value output by these monitoring sensors reaches an abnormal value exceeding a certain level, an alarm is activated and an alarm is issued. . On the other hand, the monitoring signal output from the monitoring sensor is recorded in a monitoring data recording device installed separately.

[0004] That is, the conventional monitoring of the signs of disaster, the transmission of alarms,
The recording of monitoring and alarm data does not constitute a series of systems.Thus, although all monitoring signals generated by monitoring sensors are recorded, it is monitored whether or not an alarm has been properly issued. No confirmation could be made from the data stored in the data recording device.

Further, in the conventional method, even when an alarm device installed in a distant place issues an alarm, the fact that the alarm is transmitted is immediately notified to the monitoring station, or the alarm device located far from the monitoring station is controlled. In order to be able to immediately issue or cancel an alarm, all of the alarms must be equipped with a transmission / reception function, which increases the equipment burden.

[0006]
