摘要:
The invention relates to a method and a system for positioning an apparatus (10) for monitoring a parameter of one or more parabolic reflectors (15) of a solar thermal field (122), wherein the method comprises positioning the apparatus (10) at a first field location (105) responsive to the position of said respective parabolic reflector (15), acquiring information of an absorber tube (38) of said respective parabolic reflector (15), and positioning the apparatus (10) at the second field location (110) responsive to the information of the absorber tube (38), the second field location (110) being beyond the focus of said respective parabolic reflector (15).

摘要:
The invention relates to a method and a system for monitoring a parameter of a parabolic reflector (15), wherein the method comprising, directing at least one light beam onto at least a portion of a surface of the parabolic reflector (15) such that the reflected at least one light beam (35) is directed beyond a focus of the parabolic reflector (15), detecting the reflected at least one light beam (35) at a location beyond the focus of the parabolic reflector (15), determining an intensity of the detected at least one light beam, and comparing the intensity with a reference intensity to estimate the parameter of the parabolic reflector (15).
