Description

technical field [0001] The invention relates to a device for measuring solar radiation, in particular to a split-turn intelligent radiation sensor, specifically a radiation sensor capable of measuring total radiation, scattered radiation and direct radiation, and belongs to the technical field of radiation sensors. Background technique [0002] Photovoltaic power generation is an ideal supplement to traditional power generation delivery systems and a clean and near-infinite energy source option in the current growing energy crisis. In assessing the value of photovoltaics, power planners need solar resource data for pre-planned sites. Sunlight reaches the Earth's surface along two paths: direct radiation from sunlight and diffuse radiation from the atmosphere. Solar direct irradiance, solar horizontal diffuse irradiance, and local temperature data are used to estimate the energy efficiency generated by fixed and tracking photovoltaic systems. These data can be used to suppo...

Problems solved by technology

[0008] 2. There is a situation where the horizontal adjustment cannot be positioned; there is no level bubble indicator that can be referred to, and because the designed horizontal adjustment arm is too small, it cannot be finely adjusted, which causes the embarrassing situation that it cannot be adjusted to the actual level; According to the research on the photoelectric master meter based on the level, the deviation of the level will directly cause a large offset to the measurement data, making the data lose credibility

[0010] 4. Mechanical vibration brings measurement error; since the optical measurement sensor 56 and the motor box are designed on a bracket 48, so when the motor 116 is working, the mechanical vibration generated is easily transmitted to the bracket where the optical measurement sensor 116 is located Tongue protruding position 68, thus causing vibration, causing the measurement data of the light measurement sensor 116 to fluctuate; affecting the accuracy of the measurement data

[0011] 5. Loosening of the rotating disk; the rotating disk on the motor 116 is fastened with a 2 mm nut, but because the force bearing area is too small, it will become loose after a long time; of course, due to the clamp design of the motor shaft and the rotating disk, the shielding The belt 136 can be guaranteed to be driven by the motor 116, but the front and rear stretching and jumping of the rotating disk in the axial direction cannot be guaranteed, thus causing the small first magnet placed on the rotating disk to fail to give an effective positioning signal to the first Hall sensor, thereby causing the motor system to The action stops abnormally, making the obtained data completely meaningless

[0012] 6. RSR uses imported foreign data collectors, which are not only expensive, but also the scattering correction algorithm does not conform to the national conditions of the country
