SYSTEM FOR CONTROLLING VENTILATING FAN IN A SUBWAY TUNNEL

摘要

PURPOSE: a kind of ventilator control system subway tunnel is provided to the measurement flows through sensor that control ventilation fan depends on dust concentration. ;CONSTITUTION: a kind of subway tunnel of ventilator control system (sulphur) includes a draft fan (100), sensor unit (200) and control unit (300). The control unit that the ventilation fan is mounted on predetermined position subway tunnel and is controlled by operation. Sensor is installed as neighbouring rear portion ventilation fan and has detected subway close to ventilation fan. Control unit controls ventilation fan, according to the signal of detection, to minimize the speed ventilation fan from sensor unit. ;The 2013 of copyright KIPO submissions;[Reference numerals] (100) ventilation blower; (200) sensor unit; (300) unit is compareed
