Ventilation and air conditioning system technical plan Station ventilation and air conditioning system includes station public area ventilation and air conditioning system (large system), equipment room ventilation and air conditioning system (small system) and air conditioning water system. A large ventilation system at a station includes the following: (1) Underground tunnel tunnel piston ventilation system and mechanical ventilation system (both smoke exhaust system), referred to as TVF system. (2) Combination group, referred to as KT system. (3) Exhaust heat fan, referred to as UOF system. (4) Back exhaust fan, referred to as HPF system. (5) Air conditioning new fan, referred to as KXF system. In these field devices, the sterilization equipment of the combined air conditioning unit air handling unit and the reversible axial exhaust fan are controlled by I/O hard wire connection. The equipment monitoring point is used to collect the operating status signals of various field devices and the control signals of the transmitting controller. According to the use and status of the field equipment monitoring point signal, the following equipment monitoring point table is listed in the signal transmission and interface mode, taking the combined air conditioning unit air handling unit (KT system) as an example. The ventilation system control scheme determines that the entire control system is to implement data communication between the station controller and each field device, and the data communication between the controller and the vehicle control room. The vehicle control room is required to be able to monitor the status of the field equipment in the ventilation system in the station in real time, and the station controller can transmit the data back to the vehicle control room in real time.
