The image processing module 320 analyzes the image and sends the analysis result to the program control module 310, and the program control module 310 outputs a driving signal to the high pressure water pump module 220 and the servo motor module 230 of the fog gun mechanism 200 according to the analysis result. The high pressure water pump module 220 supplies water to the barrel spraying module 210 after receiving the driving signal to realize the spraying function, and the servo motor module 230 drives the barrel spraying module 210 to rotate on the dust source site and adjust the spraying angle after receiving the driving signal to realize the automatic tracking function of the target. And the relevant parameter threshold value can be input or modified and a language program or the like can be written through the I/O module 330.
The barrel spraying module 210 is powered by an aviation impeller with low power consumption and reliable performance, the effective spraying distance can reach 60 meters, an European imported direct current motor can be used for accurately and quickly positioning a designated angle, the water consumption is only 1/3-1/2 of the traditional fog gun, the particle size distribution of fog drops is 10-30 microns, the adsorption and sedimentation rate of micro particles such as PM2.5 and PM10 is high, the barrel spraying module is very suitable for the dust production environment of a stockpile greenhouse, and the effect is obvious.
The program control module 310 drives the servo motor module 230 to drive the cylinder spraying module 210 to rotate on the dust source site and adjust the spraying angle, and a time domain hot gas variance analysis algorithm is adopted for analysis.
The key parameters in the moving object detection module are L in the time domain and a threshold T. Due to the fact that the resolutions of different positions are inconsistent due to the inclination of the camera angle, two pixel blocks of 2 pixels by 2 pixels are respectively selected, and spatial position information is calculated through a camera positioning and calibrating algorithm, as shown in tables 1 and 2.
As can be seen from Table 1, the 1 st pixel block is converted into physical space coordinates (width: 0.08m and height: 0.3m in physical space).
TABLE 1
As can be seen from Table 2, the 2 nd pixel block is converted into physical space coordinates (width: 0.035m, height: 0.06m of the corresponding physical space).
TABLE 2
Comparative example 1
At present, the dust suppression mode of spraying in the existing stockpile greenhouse is as follows:
the existing spraying dust suppression mode in the material pile greenhouse is that the interior of the material pile greenhouse is generally treated by adopting the linkage of a conventional fog gun and a dust concentration monitor, and when the dust concentration monitor detects that the dust concentration in the material pile greenhouse reaches a preset threshold upper limit (such as 8 mg/m)3Or 10mg/m3) When the dust suppression agent is used, starting a fog gun to spray and suppress dust; when the dust concentration monitor detects that the dust concentration in the material shed is lower than the lower limit of the preset threshold (such as 2 mg/m)3) Stopping spraying by the fog gun; the linkage treatment mode is usually carried out when dust is generated and diffused into the whole material shed and reaches a certain concentration, and the treatment has obvious hysteresis. Meanwhile, when the existing fog gun is started, the spraying mode is to horizontally rotate and spray in a reciprocating mode according to a preset program, a dust-producing target cannot be accurately tracked to spray, the treatment effect is often poor, and a large amount of water resources are wasted.

2) According to the dust production information identified by the image processing module 320, the program control module 310 is used for intelligently controlling the fog gun mechanism 200 to automatically start and track the working vehicle and the dust plume for spraying and dust reduction, so that accurate dust suppression is performed at the dust production source, the dust diffusion is reduced to the maximum extent, the treatment cost is greatly saved, and the remarkable effects of energy conservation and emission reduction are achieved.
3) The average droplet particle size of the fog gun mechanism 200 adopted by the invention is 10-30 μm, and the average droplet particle size of the traditional fog gun is 50-100 μm, so that the average droplet particle size of the fog gun mechanism 200 adopted by the invention is greatly reduced compared with the average droplet particle size of the traditional fog gun, and the removal rate of fine particle dust such as PM10, PM2.5 and the like can be greatly improved.
