Description

Technology Field

[0001] The present invention relates to a river flood evacuation guidance system. Background Technology

[0002] There are often cases where heavy rain causes flooding, resulting in the water level in rivers rising suddenly and significantly.

[0003] As such, when a flood occurs, people walking on walking paths along the riverbank may suffer damage as the river overflows.

[0004] Therefore, in the event of a flood, it is necessary to predict the direction of movement of users walking on a walking path provided along a river and flash a light source installed on the edge of the walking path and the edge of the entrance connected to the walking path in the direction of movement so that users can see the light from the flashing light source and evacuate through the nearest entrance, thereby allowing users walking on the walking path along the river to evacuate quickly from the river flood and avoid damage.

[0021] The present invention will be described in detail with reference to FIG. 2 as follows.

[0022] FIG. 2 is a flowchart showing a step-by-step example of the function of the movement direction prediction unit (40) of FIG. 1.

[0023] In FIGS. 1 and 2, a plurality of human body detection sensors (26) are installed at regular intervals along one edge of a walking path (20) provided along a river (10), and when a user (22) walking on the walking path (20) approaches, the sensors detect the user (22) and output a human body detection signal along with coordinate information, providing it to a movement direction prediction unit (40). Here, the human body detection sensors (26) are preferably infrared detection sensors.

[0024] The movement direction prediction unit (40) predicts the movement direction (24) of a user (22) who is walking from a plurality of human body detection signals and coordinate information provided sequentially from a plurality of human body detection sensors (26), outputs information regarding the predicted movement direction (24) of the user (22), and provides it to the lighting control unit (50) (steps S10 to S30 of FIG. 2).

[0025] A plurality of light-emitting means (28) are installed at regular intervals on one or both edges of the walkway (20) and on one or both edges of the entrance / exit path (30) connected to the walkway (20) to emit light. Here, it is preferable that the light-emitting means (28) be light-emitting diodes.

[0026] When flood warning information is provided, the lighting control unit (50) receives power provided by the power supply unit (60) according to the movement direction information of the user (22) provided by the movement direction prediction unit (40) and selectively provides it to a plurality of light-emitting means (28) to flash the plurality of light-emitting means (28) installed on the edge of the walking path (20) near the user (22) in the direction of movement (24) of the user (22) and on the edge of the access path (30) connected to the walking path (20) near the user (22), so that the user (22) walking sees the light from the flashing of the plurality of light-emitting means (28) and evacuates through the nearby access path (30). Here, the flood warning information may be provided through an information and communication network from the flood warning system of the relevant local government. It is preferable that the flashing of the plurality of light-emitting means (28) be collective flashing or sequential flashing.

[0027] The present invention has the advantage that, in the event of a flood occurring when a user (22) is walking on a walking path (20) provided along a river (10), the direction of movement (24) of the user (22) walking on the walking path (20) near the user (22) in the direction of movement (24) is predicted, and a light-emitting means (28) installed on the edge of the walking path (20) near the user (22) and the edge of the access road (30) connected to the walking path (20) near the user (22) is flashed so that the user (22) walking on the walking path sees the light from the flashing of the light-emitting means (28) and evacuates through the nearby access road (30), thereby allowing the user (22) walking on the walking path (20) along the river (10) to evacuate quickly from the river flood and avoid damage.
