Embodiment
Vertical rod 2 is filled on a kind of airborne dust and meteorologic parameter on-line monitoring system, including firm banking 1, firm banking, branch is installed
Vertical rod top is stretched into the lower end of frame 8, and mounting bracket lower end sets external tooth 3, vertical rod upper inside wall to set internal tooth 4, mounting bracket
The external tooth of lower end coordinates with the internal tooth of vertical rod upper inside wall, it is ensured that mounting bracket reliably rotates in vertical rod;Filled in mounting bracket
Gear coupling rotating device 30, including first gear 5, the second gear 7 that first gear drives with stepper motor 6 are engaged;By step
Stepper motor driving second gear is rotated, and then drives mounting bracket to be rotated in vertical rod;Vertical rod upper end fills limit switch mounting rod
9, the first limit switch, the second limit switch are separately positioned on the tow sides of switch mounting rod;Filled in mounting bracket spacing
Feeler lever 10 is switched, in mounting bracket rotation process, limit switch feeler lever spacing is opened 0 degree and 360 degree of positions with first respectively
Close, the second limit switch is contacted, limit switch is got an electric shock by conducting and discharge, realize the rotation protection of 0-360 degree;In mounting bracket
Top sets gradually camera 28, meteorologic parameter detection means 11 (commercially available prod), airborne dust harvester 12 from top to bottom.
The airborne dust harvester includes the first gas circuit 13, the second gas circuit 14, the 3rd gas circuit 15, the 4th gas circuit 16, first
Gas circuit, the second gas circuit, the 3rd gas circuit, the 4th gas circuit respectively with PM10 filters 17, PM2.5 filters 18, air cleaner 19,
Bulky grain filter 20 is connected, PM10 filters, two imports exported respectively with the first triple valve 21 of PM2.5 filters
Connection, air cleaner, the outlet of bulky grain filter are connected with two imports of the second triple valve 22 respectively, and first, second
The outlet of triple valve 23 is connected with two imports of the 3rd triple valve respectively, and the outlet of the 3rd triple valve is connected with air pump 24, gas
Pump is connected with drying device 25, and drying device from Zhengzhou is bright provided with particulate matter detection sensor with (containing science and technology ZH03 laser powders
The models such as dust sensor) 27 air chamber 26 communicates.
Detection case can be transmitted to host computer by wireless or cable by above-mentioned noise detection device, airborne dust harvester
(commercially available prod such as commercially available STM32F103 systems of example) is analyzed.Camera carries out the forwarding of video and the candid photograph of scene photograph,
And upload to central platform.The effect of pure air after being filtered through air cleaner is that gas circuit is cleaned, while can be with
