Intelligent electric air valve control system and method applied in urban rail traffic

Abstract

The invention discloses an intelligent electric air valve control system and method applied in urban rail traffic. The control system comprises a circuit center monitoring system, a station level controller, an upper monitoring system controller, an intelligent electric air valve control box, an intelligent electric fan control box and a network communication bus, wherein an intelligent electric air valve controller is arranged in the intelligent electric air valve control box; the intelligent electric air valve controller is electrically connected with a plurality of intermediate relays; theintermediate relays are electrically connected with an air valve actuator; the air valve actuator is connected with an electric air valve; and the intelligent electric air valve controller is also connected with a display in a communication manner. According to the control system, the quantity of power distribution loops and the quantity of cables can be decreased, elements in the electric air valve control box are few, and the wiring is simple, so that the scale of civil engineering of a station can be reduced to the great extent, the energy of the air valve and the power quality can be managed conveniently, and the operation and maintenance of the air valve can be facilitated.

Description

technical field [0001] The invention relates to the technical field of electric air valve control, in particular to an intelligent electric air valve control system and method applied to urban rail transit. Background technique [0002] In order to improve the air quality of urban rail transit underground stations and ensure the smoke prevention and exhaust function in the event of a fire in the rail transit system, a large number of fans and dampers are installed in the ventilation and air-conditioning systems of rail transit stations and tunnel ventilation systems to facilitate transportation from the ground to the underground. Sufficient fresh air and discharge of underground waste gas and fire smoke ensure the normal and safe operation of urban rail transit. The ventilation and air conditioning system of rail transit directly affects the comfort and safety of the people. [0003] At present, the control of electric air valves in urban rail transit needs to be connected t...

AI Technical Summary

Problems solved by technology

[0003] At present, the control of electric air valves in urban rail transit needs to be connected through a large number of cables. There are many components in the box, which makes the air valve control box bulky and takes up a lot of space, which increases the scale of the civil construction of the station
