Business Description

With global climate change, heavy rain, thunder and lightning, hail, and high temperature have frequently appeared since June. These extreme climates have had a major impact on human production and life. Among them, unsafe events caused by extreme weather will also have a greater impact on the safe operation of the airport.
The main impact of precipitation on aircraft flight is that precipitation reduces the visibility during take-off and landing. Because of poor visibility, it poses a huge threat to flight safety. In addition, it may also cause adverse weather effects such as stagnant water, slippery, turbulence, wind shear, etc., which seriously threatens flight safety. The most recent international flight accident statistics show that among more than 80 first-class accidents, 39% of the accidents are caused by meteorological reasons. It can be seen that the meteorological causes of precipitation pose a serious threat to the safety of civil aviation flight, and directly threaten the safety of people's lives and properties. Therefore, the impact of precipitation on safe flight cannot be ignored.
Precipitation is an important indicator to measure the strength and quantity of precipitation. In meteorological terminology, rain, snow and hail are collectively referred to as precipitation in meteorological terms. The depth that precipitation accumulates on the horizontal surface without evaporation, infiltration and loss after falling to the ground is called precipitation. How to measure precipitation? Precipitation is measured with a special precipitation measuring cup. Liquid precipitation is to measure the precipitation in the special rain gauge directly with a measuring cup, and solid precipitation is to take the rain gauge containing solid precipitation back to the room, make it melt and measure the precipitation, which is the precipitation in this period (snow). ) in millimeters.
In the former airports, tipping bucket rain gauges were used to measure precipitation, to be precise, rainfall. For solid precipitation, such as hail and snow, tipping bucket rain gauges cannot measure. The rainwater falling into the tipping bucket rain gauge enters the water container from the uppermost water receiving port, falls into the water receiving funnel, and flows into the tipping bucket through the funnel mouth. When the accumulated water reaches a certain height (such as 0.01mm), the tipping bucket loses its balance and overturns. Every time the bucket dumps, the switch turns on the circuit and sends a pulse signal to the recorder. The recorder records the rainfall. In this way, the rainfall process can be measured. Such a design will cause the loss of precipitation during the dumping process, and at the same time, it is also necessary to regularly maintain and remove the sludge in the drum to ensure the normal operation of the equipment.
The weighing rain gauge uses the high-precision electronic weighing principle to measure all types of precipitation. The high-precision weight sensor can measure the rainfall intensity at the same time, and the internal electronic balance system can also measure the rainwater evaporation with high precision. It can be equipped with an inverted siphon automatic drainage system and heating device, which is not affected by external weather changes. Low power consumption intelligent output, solar power or 12V battery power can work normally.
In winter, antifreeze can be added to the rain gauge to measure snowfall, and the snow will melt directly in the rain gauge without accumulating and freezing.
The instrument has its own wind compensation and precipitation detection functions, which can be used normally even in strong wind areas, and the wind shield accessories can better adapt to the northwest and other areas with large sandstorms.
