Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0014] Such as Figure 1-3 As shown, a sun tracking system for occultation flux telemetry includes a spectrometer 10 and an optical assembly, the optical assembly can use reflection or refraction to guide sunlight into the spectrometer 10, and the optical assembly includes a first reflector 21 and the second reflector 22, wherein the first reflector 21 is the first optical assembly for receiving sunlight, and the sunlight becomes a vertical beam after being reflected by the first and second reflectors 21 and 22 in turn, the The vertical light beam enters the spectrometer 10 after being reflected and / or refracted by the downstream optical components, and the spectrometer 10 is electrically connected to the computer 30; a light-through hole 23 is provided on the light-receiving area of the second reflector 22, and passes through the light-through hole 23 The sunligh...

The present invention belongs to the atmospheric monitoring technology field, and especially relates to a solar tracking system for occultation flux remote measurement. The system comprises a spectrometer and an optical module, the optical module comprises a first reflector and a second reflector, the sunlight is changed to vertical light beam through reflection of the first reflector and the second reflector in order, the light interception area of the second reflector is provided with a light through hole, the sunlight passing through the light through hole forms a branch optical path, and the branch optical path is projected on a PSD position sensor through the reflection and / or refraction of a downstream optical module. The solar tracking system for occultation flux remote measurement employs the PSD position sensor to detect the angle of the sunlight, regulate the sunlight receiving angle of an occultation flux remote measurement device in real time according to the detection data to ensure that the luminous flux of the spectrometer is always kept at the maximum value, and the solar tracking system for occultation flux remote measurement is far better than the current device whatever in the response speed or the detection precision.
Description
technical field [0001] The invention belongs to the technical field of atmospheric monitoring, and in particular relates to a sun tracking system for remote measurement of occultation flux. Background technique [0002] The solar tracking system is used for the spectrum acquisition and analysis system when solar power is generated and the atmosphere is monitored. The current mainstream method of the sun tracking system for solar power generation is to use a dual-axis automatic tracking system. The pitch axis is used to adjust the pitch angle of the solar panel, and the azimuth axis is used to control the solar panel to track the change of the sun's azimuth angle. According to the astronomical algorithm, The position information of the sun at a certain time and place, and use this as a control signal to adjust the state of the solar panel. The SOF (infrared occultation flux detection) system is mainly composed of two modules: the sun tracking system and the spectrometer. Amo...
