Embodiment 1

[0034] This embodiment provides a dust concentration uniformity detection device, please refer to the attached figure 1 , 2 ,include:

[0035] Dynamic dust feeding device 8;

[0036] The dust collection air cylinder 3 accommodates the dust emitted by the dynamic dust feeding device 8;

[0037] A plurality of dust concentration sensors 4 are scattered and installed in the detection section of the dust collection air cylinder 3;

[0038] The main control module 5 acquires the dust concentration collected by the dust concentration sensor 4 in real time.

[0039] As a preferred embodiment, the dynamic dust feeding device 8 includes a cross slide module 1 and a dust generating device 2, and the dust generating device 2 or the dust generating port of the dust generating device 2 is installed on the cross slide die On group 1, the cross slide module 1 drives the dust generating device 1 or the dust generating port of the dust generating device 2 to move up, down, left, and right....

Embodiment 2

[0043] This embodiment provides a dust concentration uniformity control system, please refer to the attached image 3 , 4 ,include:

[0044] Dust generating position generation module 10, according to the dust concentration value data distribution fed back by dust concentration sensors 4 in several different positions within a certain period of time and the target dust concentration value set by default, using fuzzy information fusion algorithm to generate a number of dust concentration values The resulting coordinate values ​​of the data fusion are mapped to the X-Y plane coordinates, and the next dust generation position data of the dust generation port of the dynamic dust feeding device 8 is generated and output;

[0045] The dust generation module 11 generates and outputs the next dust generation data of the dynamic dust feeding device 8 according to the difference between the dust concentration value measured in real time by the dust concentration sensor 4 and the set ta...

Abstract

The invention discloses a dust concentration uniformity detection device and a dust concentration uniformity control system. The detection device comprises a dynamic dust supply device; a dust collection air duct used for accommodating dust sent by the dynamic dust supply device; a plurality of dust concentration sensors dispersedly mounted in the detection section of the dust collection air duct; and a main control module which is used for acquiring the dust concentration collected by the dust concentration sensor in real time. The control system comprises a dust generating position generating module which generates and outputs next dust generating position data of a dust generating opening of the dynamic dust supplying device; a dust generation module which is used for generating and outputting next dust generation data of the dynamic dust supply device; and a dust generation control module which is used for controlling the position and the dust generation amount of a dust generation opening of the dynamic dust supply device according to the dust generation position data and the dust generation amount data. According to the invention, a dust environment with uniform concentration can be flexibly and efficiently provided according to different scenes, and verification of a dust concentration measuring instrument is facilitated.

Description

technical field [0001] The invention relates to the field of environmental detection, in particular to a dust concentration uniformity detection device and a control system. Background technique [0002] Dust can cause damage to electromechanical equipment and affect its normal working life. Once the explosion-prone dust meets the explosion conditions, dust explosion can occur under the action of appropriate energy and ignition source. Therefore, the measurement of dust concentration has become the focus of mine safety production. heavy. At the same time, the problem of dust pollution in the air environment in our country is increasing day by day. PM10 and PM2.5 have gradually risen to become the main air pollutants in the ambient air in many cities in our country, causing major harm to human health, environment, climate and atmospheric visibility. The control of particulate matter emissions has also become a priority concern for international environmental protection. Dus...
