THE IMPORTANCE OF THE DATA TAKEN FROM THE NO, NO2, AND CO SENSORS IN THE VENTILATION PROCESS IN THE RAILWAY TUNNELS

In railway tunnels, ventilation is carried out to prevent NO, NO2, and CO gas pollution caused by exhaust gases due the diesel locomotives on railway. Some calculations are used during ventilation. these calculations, factors like location structure of tunnel pressure belts that may occur should be considered one one. After control scenarios prepared based locations dimensions equipment used. Programmable logic controllers (PLC) scenarios. this system, data needed for devices work efficiently correctly. These obtained in real-time through sensors. sensors measure toxic gases. The information received from provides necessary start, continue, stop or switch other provide required operate jet fans axial ventilate tunnels. This article describes programmable process
