Abstract
The utility model is an automatic measuring system for multiple-objective surface albedo, comprising the track, moving platform, moving draught system, controller, a radiation meter, and a data collecting instrument and so on. The moving platform is positioned on the track through the suspending wheel. The two ends of the draught wire rope is provided with the moving platform and the driving wheel and the crown block tow the wire rope to from a loop at the whole journey of the track. The lower part of the wire rope is restricted and towed by the traveling block so as not to let it sag down. The crown block, driving wheel and the draught wire rope are all positioned on the vertical section of the track' s central line. The detecting face of the radiation meter that is respectively pointed up and pointed down is positioned at one side of the moving platform, while the data collecting instrument is positioned at the other side of the moving platform. Under the control of the controller, the stepping electric machine drives the driving wheel to rotate and drives the moving platform to move on the track. The utility model only applies the method with one meter corresponding to a plurality of objectives to conduct automatic measurement. Therefore, the utility model has reduced the systematic cost and eliminated the relative error of the measurement and secured the consistency of the data.
