摘要
论述设计了一个便携式紫外线强度检测仪。系统采用超低功耗16位单片机MSP430F149作为系统的控制核心。高灵敏性的UVM30紫外线传感器将采集到的紫外线强度转换为电压送给单片机处理后同国际紫外线强度分级标准对比后实时显示,同时本地具有数据备份功能以供查询。系统具有有线和无线通信接口,为多点组网观测紫外线强度提供了技术保障。所设计的系统具有测量准确、功耗低、便携式等特点,具有较强的市场推广价值。
The design of a portable UV strength meter is elaborated.The low power consumption16-bit SCM MSP430F149 is taken as a control core of the system.The UV strength collected by high sensitivity UVM30 UV transducer is converted into voltage for processing by SCM MSP430F149,and then the data processed by SCM is compared with the international UV strength standard data.The comparison result is displayed timely.At the same time,a data backup is ready for query.This system has both wire and wireless communication interfaces which can provide a technical support for multi-point network monitoring of UV strength.This newly designed system has the characteristics of high accuracy and low power consumption,and is portable.
