【摘要】 针对传统透射式能见度测量系统占地面积大、光学系统难以对准等缺陷,根据透射法原理,利用自制的仪器测量空气能见度,通过数据采集卡及LabVIEW编程,实现了对能见度数值的实时测量记录,在0~500m范围内有较好的测量精度,可应用于需要测量雾霾等天气情况下能见度数值的场所。更多还原

【Abstract】 According to the principle of the transmission method,the home-made instruments are used to measure air visibility through data acquisition card and LabVIEW programming to record real time measurement of the visibility values.To improve the traditional visibility measurement system,the shortcoming of covering a large area and optical system difficult to align are overcome.The device is preferable measurement accuracy within the range of 0~500mand can be used in visibility measurement conditions such as fog and haze.更多还原
