Description

The present invention relates to a technique for monitoring a flooded situation in an area where flooding is likely to occur in an urban area or the like.

The staff is a kind of ruler generally used for leveling, but in recent years, it has been used as a ruler for grasping the inundation situation due to heavy rain such as guerrillas (Non-Patent Document 1).

When the staff is used to monitor the inundation status, the inundation status is visually confirmed, so it is not possible to collect water level information during the inundation in real time. In addition, the inundation status cannot be grasped from a distance.

Due to the current situation, there are some cases where the inundation situation is collected by using the staff, and it may not be possible to collect information under the situation where the cooperation of the residents cannot be obtained. For example, it is not easy to read the graduations on the staff when it is dangerous to approach due to flooding or in the darkness at night.

A liquid level sensor device and a water immersion monitoring system disclosed in Patent Document 1, for example, are known as a water infiltration monitoring device and a system thereof that address the above problems. In this system, information on the liquid level of the inundation detected by the liquid level sensor device is transmitted to the host computer.
