Title:
IMPELLER POSTURE INFORMATION OBTAINING METHOD AND NACELLE-TYPE LASER RADAR
Document Type and Number:
WIPO Patent Application WO/2020/051785
Kind Code:
A1
Abstract:
Provided are an impeller posture information obtaining method and a nacelle-type laser radar (100). When it is detected that a light signal transmitted from a laser (110) is shielded by an impeller on a fan, a signal processor (140) controls a pulse generator (130) to transmit a ranging pulse signal (S110); then a frequency modulator (120) modulates the ranging pulse signal and the light signal to form a first light pulse signal and transmit same (S120); the signal processor (140) receives a reflection signal returned the impeller after the impeller reflects the first light pulse signal (S130); the signal processor (140) calculates a distance between the nacelle-type laser radar (100) and the impeller according to the preset number of sampling points of the reflection signal (S140); the signal processor (140) obtains the posture information of the impeller according to the distance (S150). The posture information of the impeller is obtained by means of the nacelle-type laser radar (100), so that the posture information of the impeller can be monitored in real time, and valid data is provided so as to maximize power generation efficiency.
