Problems solved by technology

[0004] At present, the instrument used to measure the visibility of aviation operations is the scattering measuring instrument, which is widely used in the aviation field because of its small size and high cost performance. The scattering measuring instrument calculates the visibility by measuring the transparency of the atmosphere. Since the generator and receiver are generally installed in the exposed atmosphere, in the event of haze weather, impurities such as water mist and dust in the air will be pre-bonded on the generator and receiver. Surface, affecting its optical range, increasing the error value of measurement data, making it easy for the air station to make wrong instructions, resulting in economic losses

Abstract

The invention discloses a haze weather visibility scattering type measurement method. The method comprises the following steps: carrying out preparation work: arranging a scattering type measurement instrument body capable of carrying out scattering type measurement on visibility of an aviation environment at an airport; carrying out pretreatment: when haze weather occurs, the measuring instrument controller controls a temperature sensing controller in advance; electrifying an electric heating guide ring; when the visibility is detected in hazy weather, a light-transmitting lens is cleaned in advance through a bionic transient film, water mist, dust and other impurities on the surface of the light-transmitting lens are effectively cleaned, the permeability of the light-transmitting lens is improved, the optical viewing ranges of the measurement generator and the measurement receiver are effectively guaranteed, and the error value of measurement data is reduced. An aviation station is assisted to make a correct instruction, economic losses caused by weather reasons are reduced, the accuracy of aviation visibility is further improved through repeated measurement, and the safety of aviation operation is improved.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a scattering measurement method for visibility in haze weather. Background technique [0002] Haze is a combination of fog and haze. Smog is common in cities. In many areas of China, fog is combined with haze as a disastrous weather phenomenon for early warning and forecasting, collectively referred to as "smog weather". Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-density population will inevitably emit a large amount of fine particulate matter (PM 2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. range of smog. [0003] When smog occurs, due to poor air quality and low visibility, it is easy to cause traffic jams and traffic accidents. Visibility refers to the maximum h...
