Integrated air valve control unit and air valve control system

Abstract

The invention discloses an integrated air valve control unit and air valve control system which comprises a control signal inputting module, an intelligent controller, a wire control execution module and a feedback module. The control signal inputting module comprises a local control component, a remote control component and a mode switching component. The wire control execution module comprises at least two control stages for controlling on and off of an intelligent controller and an air valve driving circuit and an interface module. The feedback module is arranged between the intelligent controller and one control stage. The intelligent controller is in signal connection with an air valve position detecting device arranged on an air valve and controls on and off of one control stage. By adopting the scheme, the wiring complication degree of an air valve control box is reduced, so that the wiring difficulty reduction and maintainability and safety improvement of the whole air valve control system in a later period are achieved. Due to the fact that an integrated air valve control unit is adopted, the size of the air valve control unit is decreased, and occupied space is decreased.

Description

Technical field [0001] The invention relates to the technical field of fan control, and more specifically, it relates to an integrated air valve control unit and an air valve control system. Background technique [0002] In order to maintain the flow of air and ensure the temperature and humidity of the environment in subway tunnels and station halls, multiple axial fans are often installed in subway tunnels. The axial flow fan is generally controlled by the air valve. The above-mentioned air valve is usually set in the environmental control ventilation control cabinet. In the traditional scheme, a single-phase air valve control unit is mainly composed of 5 intermediate relays, 3 transfer switches, 3 signal lights and 32 connectors. It takes up 1 drawer circuit with a height of 200mm, and each circuit requires Lead out nearly 30 wires respectively to the air valve, linked fan, I / O, PLC, and control panel. The situation of disconnection and poor contact often occurs, which also...
