Problems solved by technology
[0003] The use of the illuminance meter is limited by some factors: the ambient temperature has an impact on the measurement results of the illuminance meter, especially in the case of a large difference between the ambient temperature at the time of measurement and the ambient temperature at the time of calibration, such as cold winter or hot summer. more significant
In the illuminance meter, not only the photocell, but also the external circuit connected to the photocell, meter resistance, etc., all change with temperature; humidity also affects the illuminance meter; the receiver is easy to age, because the aging of the receiver will directly affect the illuminance meter The measurement accuracy of the light meter is shortened, and the service life of the illuminance meter is shortened.
[0004] Although traditional illuminance meters can achieve high measurement accuracy, they are easily affected by factors such as electromagnetic interference, active power supply, unstable remote signal transmission, and limited data transmission capacity in complex measurement environments, or are subject to harsh environments. Damage, less reliability and safety

The invention provides an illumination intensity measuring system. Based on a fiber grating sensor and in combination with a solar panel and a constant magnetic field, illumination intensity measurement can be realized, and problems that the existing photometer illumination intensity measuring method is in need of active power supply, poor in electromagnetic interference resistance, instable in remote signal transmission and limited in data transmission capacity and the like can be solved.
Description
technical field [0001] The invention relates to the field of light intensity measurement, and more specifically, to a light intensity measurement system. Background technique [0002] At present, for the measurement method of illuminance, the illuminance meter is generally used for measurement. The illuminance meter can measure the intensity of different wavelengths (such as the measurement of visible light band and ultraviolet band), and can provide people with accurate measurement results. Illuminance meters are usually composed of selenium photocells or silicon photocells and microammeters, and are currently widely used in scientific research, production, military industry, electronics, textiles, film and television, construction, transportation, medical care, sanitation and epidemic prevention and other professional fields. [0003] The use of the illuminance meter is limited by some factors: the ambient temperature has an impact on the measurement results of the illumi...
