Problems solved by technology

[0006] The disadvantages of the above-mentioned system are: it can only monitor the data of a certain fixed point on the ground of the construction site, and the analyzability and representativeness of the data are poor; it is impossible to analyze the dust distribution and diffusion of the entire construction site, and there are missed inspections and missing data and other issues; it is impossible to carry out comprehensive and accurate supervision of the dust on the construction site
[0007] Aiming at the real-time lag, space limitation, and low precision of the existing construction site dust monitoring, the present invention provides a construction site dust monitoring system based on UAV technology

Embodiment 1

[0081] At 15:55 on June 28, 2017, the location was Miaofeng Mountain Scenic Area. The maximum flight altitude was 260 meters. It took off next to Provincial Highway 101 and reached the highest point after about 7 minutes. Stop mode monitoring (each floor is about 40m high), after flying for about 13 minutes, land to the take-off point, and the gas sampling port is at the same height as the propeller. The operation interface of the test system is as follows: Figure 13 shown.

[0082] Figure 14-Figure 23 It is the relationship diagram between the spatial position and various monitoring parameters. in the Figure 14-Figure 23 Among them, a) is a 3D map of the flight track-data, the X-axis is the longitude, the Y-axis is the latitude, the Z-axis is the altitude, and the gray scale represents the concentration of the measured parameter; b) is the top view of the flight track; c) and d) are Side view of the flight path.

[0083] Depend on Figure 14 It can be seen that withi...

Embodiment 2

[0089] At 14:30 on June 28, 2017, the location was Miaofeng Mountain Scenic Area. The maximum flight altitude was 500 meters. It took off next to Provincial Highway 101 and reached the highest point about 8 minutes later. Stop mode monitoring, after flying for about 15 minutes, land to the take-off point, the height of the gas sampling port is about 40cm higher than the propeller.

[0090] The data of embodiment 2 such as Figure 19 , Figure 20 , Figure 21 , Figure 22 with Figure 23 shown. Analysis and Summary

[0091] From the comparison of the test data of the above two embodiments, it can be seen that the change of the particulate matter data in the first embodiment is more obvious, mainly because the propeller blades have an impact on the air inlet speed of the gas sampling port during the flight, so when the UAV is in an emergency When starting and stopping in an emergency, the data changes greatly; in Example 2, the position of the gas sampling port is increase...

Abstract

The invention provides a flying dust monitoring system based on an unmanned aerial vehicle. The flying dust monitoring system comprises an unmanned aerial vehicle system, a flying dust monitoring sensor system, a network transmission module and a cloud platform data processing system. According to the flying dust monitoring system, the flying dust data of a construction site field can be accurately collected in real time, the defects of manual fixed-point type flying dust monitoring at present are eliminated, and the problems of the real-time hysteresis, the space limitation, the low accuracyand the like of a traditional flying dust monitoring system are overcome.

Description

technical field [0001] The invention relates to a dust monitoring system. More specifically, the present invention relates to a UAV-based dust monitoring system. Background technique [0002] Construction site dust pollution is the fugitive particle pollution emitted during the construction process. It includes not only the primary dust caused by various construction links inside the construction site, but also the dust caused by construction transport vehicles sticking with soil and building materials spilled on the road outside the construction site. The secondary traffic caused by dust. [0003] According to the monitoring and analysis of the Beijing Municipal Environmental Protection Department, dust pollution accounts for about 15.8% of PM2.5 sources. Among the six major pollution sources in Nanjing, the proportion of dust is the largest, reaching 37.28%. Since the emission height of dust from construction sites is generally low and tends to be concentrated in densel...
