Problems solved by technology

[0003] Since one period or certain periods of the day is the peak period of garage use, the traffic flow will be relatively large. When the fan works to ventilate and reduce the CO concentration to the standard, the CO concentration in the garage will exceed the standard after one or two minutes. Start the controller and the induced fan to work again, so that the continuous start and shutdown will have a great impact on the service life of the controller and the induced fan

Abstract

The invention provides an induced fan controller, belongs to the technical field of fan control and solves the problem that service life of an induced fan is shortened due to the fact that an existing induced fan controller continuously starts and stops the induced fan during a using peak period of a garage. The induced fan controller comprises a single chip microcomputer, a peripheral circuit of the single chip microcomputer, a transformer, an input module, a CO detection circuit, a temperature detection circuit, a display module and a relay, the transformer, the input module, the CO detection circuit, the temperature detection circuit, the display module and the relay are connected with the single chip microcomputer, the transformer is connected with an outside power source, a rectifier voltage stabilizing circuit is connected between the transformer and the single chip microcomputer, the relay is connected with the induced fan, and the peripheral circuit comprises a timing start circuit which is connected with the single chip microcomputer. The induced fan controller has the advantage that a start working state is maintained during the using peak period of the garage to protect the induced fan better.

Description

technical field [0001] The invention belongs to the technical field of fan control, and relates to an induced fan controller. Background technique [0002] In recent years, with the continuous increase in the number of cars, a large amount of exhaust gas will be emitted when the car enters and exits the underground garage. Because the air in the underground garage is not easy to circulate, the CO concentration in the underground garage is seriously exceeded. In order to solve the serious problem of CO concentration exceeding the standard, generally Induced fans and induced fan controllers will be installed in the underground garage to detect and ventilate the CO concentration in the underground garage in time to reduce the CO concentration. [0003] Since one period or certain periods of the day is the peak period of garage use, the traffic flow will be relatively large. When the fan works to ventilate and reduce the CO concentration to the standard, the CO concentration in ...
