A bracket is mounted on a fiber-optical probe in the opposite direction of the sun; solar facula projected from a small hole in the bracket of a camera is positioned on a horizontal bracket with grid coordinates; the camera captures the image of the solar facula to a controller; the controller calculates the target location of the facula according to the acquisition date, time, and longitude and latitude of a Beidou chip and the geometric size of the bracket; a step motor is controlled to adjust the horizontal bracket to the target location and to keep the state; an elastic clip fixes the fiber-optical probe on the rotating bracket; a tilt sensor detects the included angle between the fiber-optical probe and the horizontal plane; when the angle deviates a setting value, the controller controls a stepping motor to rotate to adjust the fiber-optical probe to be the set value. The intelligent bracket reduces the fluctuation of the angle when the fiber-optical probe acquires data, improves the measurement precision, and accurately records the value of the angle when the fiber-optical probe acquires the data, so that a condition for reducing a measurement error of the spectra measurer during the subsequent data processing is provided.
