Direct solar radiation measuring system applied to mobile atmosphere observation platform

Abstract

The invention provides a direct solar radiation measuring system capable of being applied to a mobile atmosphere observation platform. The direct solar radiation measuring system comprises a mountingbase and a triaxial self-stabilizing platform, wherein the triaxial self-stabilizing platform comprises a gyroscope sensor, a heading direction rotating shaft, a rolling rotating shaft and a pitchingrotating shaft; the pitching rotating shaft is fixedly connected with a mono- / multi- / high-spectral irradiance radiometer, a camera and an attitude sensor, the mono- / multi- / high-spectral irradiance radiometer and the camera are adjacently arranged in parallel and are fixedly connected to form an observation group with the same field of vision; a GPS (Global Positioning System) antenna and an electronic compass are further arranged on the triaxial self-stabilizing platform; a circuit board and a power supply are arranged in the mounting base, and the circuit board is used for controlling movement of the three rotating shafts and receiving, storing and processing data; the power supply is used for supplying power to all sensors, the GPS antenna, the electronic compass and the circuit board onthe triaxial self-stabilizing platform. The measuring system provided by the invention can effectively achieve vehicle-mounted, shipborne and airborne dynamic real-time underway automatic measurementand provides a new automated measuring method for atmospheric measurement.

Description

technical field [0001] The invention relates to a single wavelength / multiple / hyperspectral solar direct radiation measurement device and method capable of inverting atmospheric composition parameters. Background technique [0002] With the development of modernization, the burning of fossil fuels, industrial emissions, and changes in land types caused by human activities have caused tremendous changes in the global atmosphere. Scientists and governments are increasingly concerned about the atmospheric environment, especially the various components in the atmosphere, which not only affect regional air quality, but also have an immeasurable impact on climate change [2015, Zhang Xingying]. Obtaining long-term stable atmospheric composition data is crucial to monitoring the atmospheric environment and predicting environmental changes. Atmospheric research is currently focused on aerosols, water vapor, ozone, CO 2 , SO 2 , NO and other components, and analyze the changes in cl...

Problems solved by technology

We found that the CE318 solar photometer can only measure at fixed points. When it is necessary to measure data at different locations, the original equipment can only be disassembled and then reassembled to the target location for measurement and observation. This undoubtedly greatly reduces the measurement efficiency. ; and the equipment is greatly affected by the site and daily maintenance. The cost of equipment purchase, site maintenance and personnel costs at the measurement point is relatively large, and it requires a high cost to maintain the observatory; the most important point is that when people use the sun When the photometer is observing, if it is found that there are clouds in the sky and other interference factors affecting the observation, the detection can be stopped until the atmospheric conditions are suitable.

However, CE318 is a heliophotometer that automatically tracks and scans, and it takes a lot of time and energy to manually screen the data for continuous observation under the condition that the atmospheric conditions cannot be recognized.

The Microtops II solar photometer is a hand-held measuring instrument, and human measurement errors have a great impact on the measurement results; before measurement, some parameters such as time, latitude and longitude, and air pressure must be set on the instrument, and there are many types of errors, which affect the measurement results. It is relatively large; there are also problems with the backup and storage of data during the measurement process. If the equipment crashes or other accidents occur, the data does not have effective backup and storage precautions. Due to the band setting and other reasons, these two types of products can only observe atmospheric aerosols at present. parameters or ozone and water vapor, CO in the atmosphere cannot yet be observed 2 , SO 2 , NO and other components, but these gas components are also important parameters for studying the atmosphere

Moreover, the existing heliophotometer measurement technology has not yet realized dynamic navigation real-time measurement, all are real-time measurements based on fixed-point in-situ static observation
