[0025] The laser outputs laser light to the reflecting surface, and the imager forms a detection image according to the laser light reflected by the reflecting surface. Through the present invention, the optical path direction of the laser during the monitoring process can be changed according to actual environmental information during the monitoring process, so that accurate spectral information can be obtained in greenhouse gas monitoring, thereby obtaining accurate greenhouse gas concentration information, effectively ensuring the accuracy of the final greenhouse gas monitoring results and the continuity of the data, providing accurate data support for subsequent environmental governance, and being beneficial to environmental protection.

[0026] In this embodiment, the rotary bearing platform includes a bearing housing 4, a rotating shaft 8, a driving gear 2, a driven gear 7, a thrust bearing, a bearing plate 1 and a driving motor 3;

[0027] The thrust bearing is fixedly arranged at the upper end of the bearing shell and the seat ring 9 of the thrust bearing is fixedly connected to the upper end of the bearing shell 4, the shaft ring 10 of the thrust bearing is fixedly connected to the lower surface of the bearing plate 1, the upper end of the rotating shaft 8 is fixedly connected to the lower surface of the bearing plate 1, and the axis of the rotating shaft 8 passes through the centroid of the bearing plate 1, the lower end of the rotating shaft 7 is fixed to the bottom of the bearing shell through the rotating bearing 6, the driven gear is fixedly sleeved on the lower end of the rotating shaft, the driving gear is meshed with the driven gear and the driving gear is transmission-connected to the output shaft 5 of the driving motor 3, the control input end of the driving motor is connected to the control end of the control transmission unit, and the driving gear and the driven gear are both bevel gears. Through the above structure, the optical path direction of the laser can be adjusted in real time according to the actual wind direction information. After finding the direction with the least impact on the imaging quality, the real-time detection image is uploaded to the monitoring center, and the monitoring host determines the concentration of various greenhouse gases through the existing spectral analysis method.

The location module is a Beidou positioning module or a GPS positioning module; the transmission module is an Ethernet module or a wireless transmission module, and the wireless transmission module can adopt an existing 5G module, UWB module, etc.
