METHOD FOR CONTROLLING HELIOSTAT USED FOR CONDENSING OF SUNLIGHT AND DEVICE THEREOF

摘要

Provided are a method for controlling a heliostat used for the condensing of sunlight and a device thereof that achieve high sunlight condensing efficiency with a high light condensing rate, wherein a light condensing point (a focal point) of sunlight does not deviate, and have high area arrangement efficiency because a rotation by a rotation mechanism is not carried out.  The controlling method, whereby a heliostat having a plurality of reflecting mirrors and used for condensing sunlight is controlled to track the moving sun, reflect the sunlight, and condense the sunlight into a predetermined focal point, comprises a step in which the plurality of reflecting mirrors are adjusted to have a focal point at a predetermined distance and a step in which the plurality of reflecting mirrors, which are configured to move and incline in linkage with each other, are adjusted to track the sun and the light reflecting from the reflecting mirrors are adjusted to have a focal point at an arbitrary point, thereby driving the respective reflecting mirrors in linkage with each other while maintaining the condition wherein the coordinates of the predetermined points of the reflecting mirrors are fixed.
