Calibration system of atmosphere visibility meter and calibration method thereof

Abstract

The technical problem to be solved of the invention aims at providing a system for fast, conveniently and exactly calibrating an atmosphere visibility meter. The calibration system of the atmosphere visibility meter comprises a gradual change ratio light attenuation lens; the gradual change ratio light attenuation lens is positioned on an optical path between the transmitting end of the visibilitymeter and the receiving end of the visibility meter; and the gradual change ratio light attenuation lens, the transmitting end and the receiving end are positioned in cleaning atmospheric space. Theinvention completely considers the affects such as environment, temperature, weather variation, and the like, and can conveniently and fast calibrate the atmosphere visibility meter; by adopting the system, one atmosphere visibility meter can be calibrated only with 4-8 hours; the system has low system energy consumption and no environment pollution, and is convenient in operating and controlling;and the invention precludes the difficulties to the calibration of the atmosphere visibility meter, which are caused by human beings, weather, environment, temperature, humidity level, time, and thelike, and can scientifically, objectively and fast calibrate the various atmosphere visibility meters.

Description

technical field [0001] The invention relates to a calibration system and a calibration method for an atmospheric visibility meter. Background technique [0002] Since the 1980s, with the rapid development of optoelectronic technology, the development of automatic meteorological, traffic meteorological, aviation, hydrological, forest, airport and other meteorological monitoring has been promoted, and corresponding monitoring systems and products have also emerged as the times require. Visibility meters offer a multitude of practical applications. [0003] At present, the visibility meters developed and produced mainly include transmission type, scattering type, camera type, laser radar and so on. So far, there is no simple and convenient calibration system or device for the known visibility meters developed and produced at home and abroad. At present, it is generally used in the natural environment to operate the distance of several measured points by people, and divide the...

Problems solved by technology

However, the error caused by the transfer method is various, such as: human subjectivity; the optical characteristics of the target itself; the directionality of the target distance; the cause of weather changes; the temperature, humidity, wind, smoke, dust, etc. In addition, there are also disadvantages such as long calibration time, which generally takes ten days as a count, which causes great difficulties for the calibration of the visibility meter. In this way, the accuracy error of the visibility meter calibrated is It is conceivable that its reliability will be greatly reduced, which will cause a lot of trouble for the development and production of the visibility meter
