Full-radiation environment calibration device for photoelectric heliograph

Abstract

The invention relates to a calibration device for a photoelectric heliograph and relates to the technical field of meteorological instrument detection, the calibration device for the photoelectric heliograph solves the problems that the existing heliograph cannot continuously work outdoors for a long time, the test data is discontinuous and the test time is long, resulting in low calibration efficiency; moreover, the majority of the existing indoor calibration devices do not simulate the radiation environment, such that the measurement precision and the like of the heliograph are reduced. Thecalibration device comprises a fixed support, a solar simulator, a sun-earth motion simulation mechanism and a radiation environment simulation room. The solar simulator is fastened on the fixed support, the emitted collimated light beams are reflected to a to-be-detected photoelectric heliograph through a plane mirror, the to-be-detected heliograph is clamped on a high-precision optical rotary platform through a clamp, so that height angle adjustment and azimuth angle adjustment are achieved, and different illumination angles of the sun are simulated; the influence of different air temperatures and humidity, and air quality on the radiation effect in the solar radiation environment is simulated through the radiation environment simulation room. According to the calibration device for thephotoelectric heliograph in the invention, the workload of operators is reduced, and the calibration efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of meteorological instrument detection, in particular to a full-radiation environment calibration device for a photoelectric sunshine meter. Background technique [0002] The photoelectric sunshine meter is a meteorological instrument that records the sunshine hours. Due to its characteristics of low cost, fast response, good safety and reliability, low cost and maintenance cost, it is now widely used in solar energy resource measurement, meteorological radiation observation and other fields. [0003] The calibration test of the photoelectric sunshine meter is the key link to realize the high-precision measurement of sunshine hours. At present, under the minimum requirements, the operator uses the standard pyranometer and the insolation meter to be calibrated outdoors for comparison and measurement when performing calibration operations for the photoelectric daylight meter. When the weather is bad, the out...
