Description

technical field [0001] The invention belongs to the technical field of wind force measurement, and in particular relates to a self-powered anemometer. Background technique [0002] Wind direction and wind speed measurement technology has a wide range of application requirements in meteorology, civil aviation, highways and bridges, and mining industries. At present, new sensors, data acquisition and processing technologies for wind direction and speed measurement have made great progress, among which portable digital wind speed measuring instruments have been widely used in industrial production. However, there are still some key problems that need to be solved urgently in the field of wind direction and wind speed measurement, such as data acquisition, processing and energy supply for continuous remote transmission, low wind speed start-up of the measurement system, and so on. Contents of the invention [0003] The present invention proposes a self-powered wind direction ...
