Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] See figure 1 , which is a flow chart of an embodiment of the present invention, specifically, a flow chart of an embodiment of a method for detecting dust concentration based on an air conditioner.
[0029] Such as figure 1 As shown, the method of this embodiment based on the air conditioner process dust concentration comprises the following process steps:
[0030] Step 101: The dust sensor installed on the air conditioner obtains the current air velocity within the detection range of the dust sensor according to a set sampling frequency.
[0031] Wherein, the set sampling frequency is a known and pre-stored frequency, which is used as a sampling frequency for obtaining the current air flow velocity in real time. The current air flow rate...

The invention discloses a dust concentration detection method based on an air conditioner. The method comprises steps as follows: a dust sensor acquires a current air velocity according to set sampling frequency; whether the current air velocity is changed relative to a last steady air velocity or not is judged; if the current air velocity is not changed, a last sampling time period corresponding to the last steady air velocity is used as a current sampling time period; if the current air velocity is changed, whether the current air velocity is larger than a set air velocity or not is judged; if the current air velocity is larger than the set air velocity, a sampling time period corresponding to the current air velocity is determined according to the know correspondence relation of air velocities and sampling time periods and is used as the current sampling time period; if the current air velocity is not larger than the set air velocity, a known set sampling time period is used as the current sampling time period; the dust sensor takes the current sampling time period as a working parameter to acquire and output a dust detection value. With the adoption of the method, the problem of inaccurate dust concentration detection in the prior art can be solved.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, in particular relates to an air conditioner, and more specifically relates to a dust concentration detection method based on the air conditioner. Background technique [0002] At present, there are more and more smart air conditioners, and there are more and more applications of various sensors on smart air conditioners, especially the application of air quality detection. As an air quality detection sensor, the dust sensor can emit infrared rays or lasers to irradiate the particles in the air, and obtain the dust concentration in the air according to the light intensity signal scattered or reflected by the particles, so as to realize the detection of the dust concentration. [0003] When the dust sensor detects the dust concentration, the following method is sampled to obtain the detection value and output: within the set sampling time period, the light intensity signal data fed back by...
