发明名称 APPARATUS AND METHOD FOR DUST CUT IN SUBWAY TERNAL
摘要 PURPOSE: A dust catcher in a subway tunnel and an operating method thereof are provided to prevent the inflow of dust and harmful materials from a subway tunnel to a subway platform. CONSTITUTION: A dust catcher in a subway tunnel comprises a wind speed sensor(102), a line detection sensor(101), and a dust catching unit(100). The wind speed sensor is located on a side of a rail and outputs a signal when the wind speed over the reference is detected as a subway vehicle approaches a platform. The line detection sensor is located on a rail opposite to the speed sensor and outputs a signal when the subway vehicle enters a specific rail in front of the sensor. The dust catching unit is located to be perpendicular to a bottom rail in a subway tunnel and sprays water toward the center of the tunnel in response to the signal of the wind speed sensor while stopping the water spray in response to the signal of the line detection sensor.
