摘　　要：【目的】近年来,DXC1型视程障碍现象仪陆续布设国家级地面气象观测站,台站业务人员对其了解不够全面,需要系统性了解设备的组成结构和工作原理,并提供设备基本的维修维护方法。【方法】介绍了DXC1型视程障碍现象仪组成结构和工作原理,并结合常见数据异常情况给出具体解决流程和方法。【结果】DXC1型视程障碍现象仪是一款基于气溶胶的光学散射特性的测量设备,通过精确测量气溶胶样本的光学衰减,从而自动计算出大气中PM_(10)、PM_(2.5)、PM_(1)颗粒物的质量浓度,同时结合气象观测的其他相关要素,智能识别视程障碍天气现象。【结论】为后期台站技术人员开展设备维护、维修提供指导依据。[Purposes]In recent years,the DXC1-type visual range obstacle phenomenon instrument has been successively deployed in national ground meteorological observation stations,but the operational personnel of the stations do not have a comprehensive knowledge of its structure,principle and common maintenance.Therefore,it is necessary to systematically explain the structure and working principle of the instrument,and provide the personnel with the basic maintenance methods of the instrument.[Meth⁃ods]This paper briefly introduces the composition structure and working principle of DXC1-type visual range obstacle phenomenon instrument,and also gives the specific solution process and method in combi⁃nation with common data anomalies.[Findings]The DXC1-type visual range obstacle phenomenon in⁃strument is a measurement device based on the optical scattering characteristics of aerosols.Through the accurate measurement of the optical attenuation of aerosol samples,this instrument can automatically cal⁃culate the mass concentration of PM_(10),PM_(2.5),PM_(1) particles in the atmosphere,and at the same time,com⁃bined with the meteorological observation of other relevant elements,it can identify the visual range ob⁃stacle weather phenomenon in an intelligent way.[Conclusions]This paper provides guidance for sta⁃tion technicians to carry out equipment maintenance and repair at a later stage.
