Abstract

The invention discloses an automatic multi-angle in-situ continuous observation platform system of a spectrograph and a control method. The system comprises tower-mounted equipment and a small industrial computer, wherein the tower-mounted equipment comprises a double-channel spectrometer, a rotary pan-tilt and a pan-tilt controller; the small industrial computer is used for receiving and storing data and sending control instructions to regulate operation of the system; a radiation sensor pointing to the sky and a canopy sensor pointing to an observed ground object are connected on an optical fiber of the double-channel spectrometer; the canopy sensor is mounted on the rotary pan-tilt which is connected with the small industrial computer through the pan-tilt controller, and the pan-tilt controller is used for adjusting the rotation direction, the angle interval and the time interval of the rotary pan-tilt and regulating and positioning the instantaneous position of the canopy sensor of the double-channel spectrometer. Automatic multi-angle observation can be realized, the observation angle is accurate, the observation height is not limited, observation data are not prone to loss, and an important means is provided for key process research and dimension extension research of the ecological system.

Description

technical field [0001] The invention relates to the field of spectral observation of ground objects, in particular to an in-situ continuous observation platform system and a control method of an automatic multi-angle spectrometer. Background technique [0002] In order to study physiological and ecological indicators such as vegetation distribution, canopy and ecosystem group structure, growth volume and so on under natural conditions, spectrometers are generally used for observation. The current conventional observation method is: use an instrument with a circular rotatable base, and extend an arm-like metal bracket, and then the metal end is connected to the sensor probe of the spectrometer, which can observe the experimental object from various angles within a certain observation plane Make observations. However, this kind of observation device requires a lot of manpower, less observation angles, and the observation angle is not accurate, and the observation height is li...
