太阳光紫外线强度检测技术研究

Research on the measuring of ultraviolet light in sunrays

太阳光紫外线辐射对人体健康有很大影响,因此,及时方便的监测紫外线强度指数对保护人们身体健康有重要意义。本文研究设计了具有校准功能的便携式太阳光紫外强度监测装置,它可实时监测太阳辐射强度并分档显示,该装置采用一种标准的紫外线专用传感器,光电信号经前置放大电路后,智能仪表中的单片机对信号进行数据补偿处理后显示输出。实际测量与本地气象台的测量数据进行了比对,紫外线指数测量数值与后者吻合的很好,能够满足一般的测量要求。

Ultraviolet light in sunrays has great effect on health of human beings. Therefore it is meaningful to monitor the intensity index of ultraviolet light conveniently. This paper designs a portable device measuring the intensity of ultraviolet light, which can be easily calibrated. A standard ultraviolet sensor is used. The light signal first transfers through the preamplifier circuit, and then, it is analyzed by the MCU, later the data are displayed. Actual measurement with the local meteorological measurement data for the comparison, which shows a perfect resemblance, thus the validity of the design is proofed.
