Measuring device and method of total solar radiation

Abstract

The invention discloses a measuring device and method of total solar radiation. The device comprises a total solar radiation sensing unit and a detection communication unit. The total solar radiation sensing unit comprises a round solar radiation absorbing area divided into white sectors and back sectors as many as the white sectors; the white sectors and the black sectors are spaced and mutually thermally insulated; the white sectors are provided with platinum resistors as many as those provided in the black sectors; the platinum resistors in the white sectors are mutually connected in series; the platinum resistors in the black sectors are mutually connected in series; the two sets of platinum resistors are both connected with the detection communication unit. According to the method, the total solar radiation is obtained using an RBF (radial basis function) neural network. The measuring device and method has the advantages of good timeliness, high precision, high reliability and the like and allow the solar radiation to be measured precisely and reliably under special weather conditions.

Description

technical field [0001] The invention belongs to the technical field of meteorological detection, and in particular relates to a measuring device and method for total solar radiation. Background technique [0002] There are two main types of pyranometers: photoelectric and pyroelectric. The photoelectric type mainly uses some materials to change the electrical properties of materials caused by light, and is mainly divided into photovoltaic type, photoconductive type and photoelectron emission type. The thermoelectric type generally uses a black coating on the surface to absorb solar radiation and convert it into heat. Traditional thermoelectric pyranometers generally use thermopiles to measure, use black coating to absorb solar radiation and measure through thermopiles, although traditional thermopiles can detect solar radiation very sensitively, but due to some special weather, For example, cloudy days, rainy days, and some extremely bad weather such as haze weather, sands...
