摘　　要：设计了一种前向散射式高精度能见度仪。该能见度仪接收端采用光电传感器BPV10,将发射光在空气中的散射信号,并经过放大、滤波和A/D转换取得数字信号。系统采用TMS320X2812以提高系统终端数据处理速度,采用CC2530实现无线数据传输。实验结果表明:该系统精度高、使用维护方便,能够较好满足气象站的观测要求。A high precision visibility meter based on forward scattering is designed by using photoelectric sensor. The receiver of visibility meter adopts photoelectric sensor BPV10, receive light scattering signals in air, after amplifying,filtering and AiD conversion to obtain digital signal. The system uses TMS320X2812, in order to improve data processing speed of system terminals, wireless data transmission is realized by using CC2530. Experimental results show that the system has advantage of high-precision, easy maintenance, and can meet requirements of meteorological observations.
