Abstract

The invention discloses a transmittance calculation device for a spherical cover of a total radiation sensor. The transmitting tube emits modulated light waves, and the modulated light waves are transmitted to the dome cover of the total radiation sensor through the first lens; the first photoelectric receiving tube receives the reflected light waves reflected by the first lens, and transmits the reflected light waves to the optical signal processing module; Process the first data and send the first data to the MCU processor; the second photoelectric receiving tube receives the second light wave reflected and / or scattered by the dome cover of the radiation sensor through the second lens, and sends the second light wave to the optical signal processing Module; after the second data is processed by the optical signal processing module, it is sent to the MCU processor; the MCU processor combines the preset original light wave intensity and the preset standard data to calculate the transmittance of the dome cover, and correct it according to the transmittance Data measured by the total radiation sensor.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to a transmittance calculation device for a dome cover of a total radiation sensor. Background technique [0002] Solar radiation observation is a very important project of atmospheric observation. The data of solar radiation observation have important and extensive applications in weather, climate, solar power generation, solar water heating system, building energy saving and other industries or fields. The ground-level total amount of current solar radiation is measured by a irradiance sensor. The total radiation sensor measures the total solar radiation of the plane normal to the hemisphere sky. The main principle is to use a thermocouple to generate an output voltage proportional to the radiation flux. Due to the use of spherical glass covers, measurement errors, especially thermal deviations, are reduced, so the total radiation sensor has high measurement accu...
