System and methodology for the air quality of underground railway stations

摘要

The present invention relates to an underground station (60) air quality management system and method capable of managing air quality by time and location by specifying a time zone and a place where the concentration of pollutants increases during subway station history, and the underground station (60) air quality according to the present invention The management system includes a real-time fine dust measuring device 10 installed in the underground station 60 of the hot spot, an underground LoRa communication network 20 that collects and transmits real-time fine dust measurement results measured in the underground station 60 to the ground. When real-time fine dust measurement results of one or more terrestrial LoRa networks (30) and hot spot underground stations (60) transmitting the measurement results transmitted to the ground to the central control center (50) are collected, and the measurement results exceed regulatory standards. Underground station (60) Collect real-time fine dust measurement results of the control unit (40) and hot spot underground station (60) that operate the ventilation system at a power higher than 30% of the average daily power consumption, and time, concentration, high concentration, and duration It consists of a central control station (50) that builds into a database containing items, ventilation volume, temperature, and pressure, uses the database to predict high concentration time zones and locations, and instructs the ventilation system to operate in advance.
