Description

Lowland immersion prediction system and driving method thereof

The present invention relates to a low-level immersion prediction system and a driving method thereof, and more particularly, to a low-level immersion prediction system using a video captured by CCTV and a driving method thereof.

Flood damage from localized torrential rains and sudden heavy rains is increasing, and due to the impact of urbanization, not only the amount of damage, but also the cost and time required to recover the damage. In particular, in large cities, damage to flooding is increasing due to the increase in impervious surfaces, changes in drainage systems, and lack of water passing capacity.

In order to minimize flood damage, it is necessary to quickly and accurately predict flood risk areas and flooding. The existing flooding prediction method takes a long time to build a model by collecting past flood data, and there is a problem that it is impossible to predict the flooding map in real time during a heavy rain.

Various studies have been conducted to predict flooding in urban areas.

However, the existing research is limited to discovering the behavior of water as a physical law and interpreting (simulating) it with a numerical analysis technique by establishing it as a governing equation. Such a study requires a lot of input data during immersion analysis, and it is difficult to generalize parameters according to regional characteristics and takes a long time to simulate, so it is not actively utilized for actual immersion prediction.

The immersion predicting unit 130 may detect a flooded area when the turbidity increases or a part of the terrain is not recognized as a conventional shape in a captured image acquired by the image acquiring unit 110.

The inundation prediction unit 130 receives the elevation difference and inclination information of the terrain according to the terrain analysis result from the terrain grasping unit 120 to predict the flow direction of the water in consideration of the flow characteristics of the water flowing from the highlands to the lowlands. Therefore, the range of flooding can be predicted.

Furthermore, the flooding prediction unit 130 may grasp the flow rate of water according to the slope according to the terrain analysis result from the terrain detection unit 120, and may further predict the speed of the flooding range. That is, in the case of a region with a high slope, the immersion proceeds rapidly, and in a region with a low slope, the progress of the immersion proceeds relatively slowly.

At this time, the parking position of the vehicle can be input by setting a regular parking area. Alternatively, when temporarily parking, parking location information may be temporarily set and input. At this time, enter the parking start time and the expected end time together.

The message notification unit 150 may transmit the flooding warning message only when the vehicle is parked in the actual flooding prediction area by transmitting the flooding warning message only within the parking start time and the expected end time.

The message notification unit 150 integrates and grasps information input through an application for exclusively predicting immersion, and transmits an immersion warning message to a user residing in an area where the immersion is predicted. have.

In an additional aspect, the CCTV cameras 20-a, 20-b, .. according to an embodiment may be implemented as a fixed type, but may also be implemented as a movable type mounted on an unmanned aerial vehicle such as a drone.

The low-level immersion prediction system 10 according to an embodiment may transmit a control signal to move the unmanned aerial vehicle equipped with a camera to the immersion prediction area when the immersion prediction area is determined by the immersion prediction unit 130.

In addition, the drone equipped with the camera moves to an expected flooding area, photographs the flooding predicted area, and provides a captured image to the low-level flooding prediction system 10 according to an embodiment.

At this time, it is possible to program the moving path of the unmanned aerial vehicle to move in the direction of flood prediction.

In addition, it may be programmed to adjust the moving speed of the drone according to the progressing speed of the flooding range predicted by the flooding prediction unit 130.

That is, in the case of a high-inclined area, the speed of the drone is rapidly set, so the speed of movement of the drone is quickly set. In the case of a low-inclined area, the speed of the drone is relatively slow. Can be set to move slowly.

In addition, the drone equipped with the camera moves to an expected flooding area, photographs the flooding predicted area, and provides a captured image to the low-level flooding prediction system 10 according to an embodiment.

The storage 160 may be implemented as a memory that stores data. In one embodiment, the storage 160 stores the terrain information identified by the terrain grasping unit 120.
