Other advantageous effects of the present invention will be further described with reference to the following embodiments.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in the figure: the utility model relates to a particulate matter on-line monitoring device 4, which comprises a hollow base 1, a controllable motor 2 and a controller 3 which are arranged inside the base 1, wherein the output shaft of the controllable motor 2 passes through the upper shell of the base 1 to be connected with the particulate matter on-line monitoring device 4, the upper shell of the base 1 is provided with a wind direction indicator 5, and the lower shell of the base 1 is provided with a display 6 and a sucker 7; particulate matter on-line monitoring device 4 and anemoscope 5 electric connection are in the input of controller 3, and controllable motor 2 and display 6 are connected in the output of controller 3. The controllable motor 2 is preferably a micro stepper motor.

During the use, base 1 adsorbs on glass through sucking disc 7, and the resident can watch the display screen through glass from home in order to know air particulate matter concentration. Further, the anemoscope 5 detects the wind direction, and the controller 3 controls the stepping motor to adjust the orientation of the particulate matter on-line monitoring device 4 according to the anemoscope 5, so that the opening of the particulate matter on-line monitoring device 4 naturally enters the wind. Preferentially, particulate matter on-line monitoring device 4 is including going into tuber pipe 8, go into 8 upper ends of tuber pipe and establish and go into 8 epaxial bevels 81 that become 45 degrees contained angles in the tuber pipe, it is equipped with monitoring room 9 to go into 8 lower extremes of tuber pipe, monitoring room 9 outside is equipped with air pump 12 and monitors indoor 9 inside beta source device 10, photomultiplier 11 of being equipped with, monitoring room 9 lateral wall is located to beta source device 10, and photomultiplier 11 locates monitoring room 9 bottoms, the gas outlet of air pump 12 link up with monitoring room 9 through outlet duct 13.
