Abstract

The invention relates to a dual-purpose fan control device. The dual-purpose fan control device comprises an exhaust signal trigger circuit, a fire-fighting signal trigger circuit, an exhaust on-off control circuit, a fire-fighting on-off control circuit, an on-off execution circuit, an exhaust fan linkage circuit and a fire-fighting fan linkage circuit, wherein direct current is accessed into theexhaust signal trigger circuit, the fire-fighting signal trigger circuit, the exhaust on-off control circuit, the fire-fighting on-off control circuit, the on-off execution circuit, the exhaust fan linkage circuit and the fire-fighting fan linkage circuit. The exhaust on-off control circuit and the fire-fighting on-off control circuit are both connected with the on-off execution circuit. The on-off execution circuit is connected with an execution mechanism of an electric valve. Alternating current is accessed to a fan starting circuit, an exhaust feedback circuit and a fire-fighting feedbackcircuit. The fan starting circuit comprises an on-off line, a coil of a contactor KM and a main contact of the contactor KM, wherein the on-off line is connected with the coil of the contactor KM, andthe main contact of the contactor KM is connected to a power distribution circuit of a dual-purpose fan in series. By adoption of the dual-purpose fan control device, the linkage relation between theelectric valve and the dual-purpose fan is integrated and perfected; and a control circuit used for exhausting at ordinary times and a control circuit used for exhausting during fire fighting are integrated, so that control is effective, and management is clear.

Description

technical field [0001] The present application relates to the field of fire control technology, in particular to a dual-purpose fan control device. Background technique [0002] A fan is a mechanical device used to move air and can be installed in a building. The fans that can be used for exhausting air at ordinary times and exhausting smoke during firefighting are dual-purpose fans. Generally, the dual-purpose fans can be started and stopped by multiple different management parties, such as building management rooms and fire control rooms. [0003] In the traditional technology, in order to realize the start-stop control of the dual-purpose fan by different management parties, the common management method is that each manager controls the dual-purpose fan through an independent control system. For example, the building property management room adopts the property management system, and the fire control room adopts the automatic fire alarm system; when the dual-purpose fan ...
