Description

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

  The scale is generally a kind of ruler used for leveling, but has recently been used as a ruler for grasping the inundation situation caused by guerrilla heavy rain (Non-patent Document 1).

  When the gauge is used for monitoring the inundation status, the inundation status is confirmed by visual observation, so that information on the water level at the time of inundation cannot be collected in real time. In addition, the inundation situation cannot be grasped from a distance.

  In this situation, the collection of inundation conditions using a gauge is dependent on the cooperation of residents, and information may not be collected in situations where the cooperation of residents cannot be obtained. For example, it is not easy to read the scale scale when it is dangerous to approach due to water immersion or in the dark such as at night.

  For example, a liquid level sensor device and an inundation monitoring system disclosed in Patent Document 1 are known as inundation monitoring devices and systems corresponding to the above problems. In this system, information on the level of the immersion water detected by the liquid level sensor device is transmitted to the host computer.

The communication unit 4 includes a communication antenna housing unit 41, a communication unit housing unit 42, and a battery unit housing unit 43.

  The communication antenna accommodation unit 41 and the communication unit accommodation unit 42 each accommodate a communication antenna and a communication module 45 compliant with the specifications of the mobile communication company.

  The battery unit housing part (battery part) 43 houses the battery unit 46. The battery unit 46 supplies power to the communication antenna, the communication module 45 and the water level measuring unit 3. A lithium battery is applied to the battery unit 46.

  The communication antenna accommodating portion 41, the communication unit accommodating portion 42, and the battery unit accommodating portion 43 are formed in a cylindrical shape having substantially the same outer diameter as that of the measuring tape main body 2, and the constituent material of the outer cylinder and the inner cylinder is the installation of the inundation monitoring measuring gauge 1. A vinyl chloride resin, stainless steel, or the like is appropriately selected according to the environment.

  The communication unit 4 is attached to the staff main body 2 in a state where the battery unit housing 43 is housed in the staff main body 2.

In addition, the water level measuring unit 3 and the communication unit 4 can be easily replaced and installed.

  An example of the inundation monitoring measure 1 will be described with reference to FIG.

  In the inundation monitoring measure 1, a measurement level of the water level based on a predetermined inundation water level and an alarm threshold are set in advance. The inundation monitoring staff 1 is normally in a sleep state. Then, when the monitoring place 10 is flooded due to rain or the like, and the water level detected by the water level measuring unit 3 eventually reaches a predetermined value, the flood monitoring standard 1 is activated. Next, the water level measurement unit 3 periodically measures the rainfall intensity. The inundation monitoring measure 1 transmits water level measurement data to the cloud server 6 based on a preset communication cycle. The transmission destination of the measurement data does not need to be a cloud server, and may be a client server. After that, when the water has submerged and the water level has reached a predetermined value or less, the water monitoring standard 1 shifts to the sleep state.

  According to the above-mentioned flood monitoring standard 1, information on the water level when the monitoring place 10 is flooded can be monitored in real time. In particular, the water level measurement unit 3 is activated periodically when the inundation occurs, detects the water level, and enters a sleep state after transmitting it to the outside, so that the power of the inundation monitoring measure 1 can be preserved. Further, since the water level information can be associated with the position information of the communication unit 4, monitoring from the remote host side can be performed.

  The inundation monitoring staff 1 is disposed at a plurality of monitoring locations 10 in the management area 5. Then, when the monitoring location 10 is inundated, the inundation monitoring measure 1 transmits information on the water level at the monitoring location 10 detected by the water level measuring unit 3 to the cloud server 6. Further, based on a request from the cloud server 6, the water level information is transmitted to the cloud server 6. Further, if the detected water level indicates a predetermined water level (for example, an alarm threshold), the water level information is transmitted to the cloud server 6.

  The water level information data is managed on the cloud and can be monitored remotely. Furthermore, the data of the water level information is mapped to the map information of the management area 5 based on the position information, and the inundation situation can be visually grasped. For example, the water level data is collected on the cloud and can be browsed ubiquitously. Therefore, it is possible to display the flooding status of the management area 5 and the operation / failure information of the flooding monitoring measure 1 and display with the graphic user interface. In addition, the inundation situation at the measurement point can be color-coded and displayed in symbols and meshes on the user's terminal (terminal such as the user's office).

  When the cloud server 6 receives the water level information from the inundation monitoring measure 1, for example, the cloud server 6 outputs map information to which the water level information is added. For example, the cloud server 6 is arranged at a base of an information providing service operated by a local government or a private company. A user who uses the information providing service can browse the map information in real time by accessing the home page of the information providing service from the display terminal 7 such as a smartphone, a tablet, or a personal computer.

  As described above, according to the inundation monitoring system of the present embodiment, it is possible to construct a monitoring system capable of confirming the inundation status at the monitoring place 10 via the cloud in real time.
