Embodiment

[0021] figure 1 It is a kind of atmospheric dust concentration detection method in the embodiment of the present invention, such as figure 1 As shown, the method includes:

[0022] Step 1: Weigh the first weight value m of the filter membrane in the dust sensor 1 .

[0023] Step 2: Install the dust sensor in the area to be tested.

[0024] Specifically, in order to collect the dust concentration in the area to be measured, it is first necessary to install a dust sensor at the measurement position of the area to be measured. The dust sensor is provided with a filter membrane, so the weight of the filter membrane needs to be weighed before installation.

[0025] Step 3: Collect the level data sent by the dust sensor at intervals of a preset period T.

[0026] Step 4: Obtain the collection flow Q according to the level data.

[0027] Further, the preset period is 6-10 minutes.

[0028] Specifically, the preset period is the interval time, that is to say, when the dust senso...

Abstract

The invention discloses an atmospheric dust concentration detection method and belongs to the technical field of air detection. The atmospheric dust concentration detection method comprises the following steps: weighing a first weight value m1 of a filter membrane in a dust sensor; mounting the dust sensor in a to-be-detected region; every other a preset period T, acquiring level data sent by thedust sensor; according to the level data, obtaining an acquisition flow Q; weighing a second weight value m2 of the filter membrane; according to the preset period T, the first weight value m1, the second weight value m2 and the acquisition flow Q, calculating dust concentration, and drawing a changing curve of the dust concentration; according to the changing curve, obtaining an influence coefficient, and calculating an estimated value of the dust concentration according to the dust concentration and the influence coefficient, so that the technical problems that the dust concentration can notbe obtained in real time and a safety accident can be easily caused by too high dust concentration in the prior art, and the technical effects that the method is simple, the dust concentration can bedetected and controlled in real time and the safety accident can be avoided are achieved.

Description

technical field [0001] The invention relates to the technical field of air detection, in particular to an atmospheric dust concentration detection method. Background technique [0002] Dust refers to fine dust particles suspended in the air. In many factories, most of the dust is a mixture of metal components, and also contains various pollutants such as particles, bacteria, dust, etc., with a wide range of particle sizes and complex shapes of dust particles. And now there will be some explosion accidents due to the concentration of dust, and it may also cause a very large impact on the workshop due to dust, which will increase the scrap rate of electronic components and waste costs. great harm. [0003] Some dust removal equipments in the prior art are for the overall dust removal of the entire workplace, and the dust concentration value cannot be obtained in real time. When the dust concentration is too high, it is easy to cause a safety accident. Contents of the inven...
