Abstract

The invention discloses a mobile-phone-controllable dual-purpose full-automatic variable-speed ventilating fan system. The signal output ends of a temperature sensor, a humidity sensor and a gas sensor are connected in parallel, are connected with an amplification circuit and a comparison circuit in sequence, and then, are split into three branches. The first branch is connected with the signal input end of a single-chip microcomputer control module; a ventilating fan rotates forwards or backwards under the control of the single-chip microcomputer control module; the second branch is connected with a trigger circuit and a thyristor circuit in sequence, and then, is connected with the ventilating fan; the third branch is connected with a sound-light alarm drive circuit, and then, is connected in parallel with a loudspeaker and a flashing light indicator; the single-chip microcomputer control module is communicated with a mobile phone terminal through a bluetooth module; and an LED display screen is connected with the signal output end of the single-chip microcomputer control module. The system reduces damage of harmful gas in the environment to human body, can realize intelligent control, provides efficient and convenient server for people and can also realize different degrees of indoor ventilation and heat radiation functions.

Description

technical field [0001] The invention relates to the fields of ventilation fan, sensor and detection technology, low-power bluetooth technology, mobile communication technology and automatic control technology, in particular to a mobile phone-based dual-purpose automatic variable-speed ventilation fan system. Background technique [0002] The existing patent CN201047359Y, a fully automatic ventilation fan for detection, alarm and ventilation, relates to a fan. Aiming at the problem that the current gas alarm cannot discharge the indoor harmful gas to the outside, it provides a detection, alarm, and ventilation automatic ventilation fan, which includes an exhaust fan, and also includes: a sensor, a signal conversion controller and an alarm The gas alarm composed of the device; the output end of the signal conversion controller is also connected with the exhaust fan. In this way, when the signal conversion controller controls the alarm to work, it also controls the exhaust fan...
