The invention discloses an anemorumbometer. The anemorumbometer comprises a data display box and a fixing box, wherein the upper end of the data display box is vertically and fixedly connected with main telescopic rods which are in sleeve connection together successively in a threaded manner by a plurality of loop bars; the upper tip of each main telescopic rod is connected with a main wind speedsensing cup through a vertical rotating shaft; each main wind speed sensing cup consists of three cup bodies which are distributed in a horizontal plane in a surrounding manner; and the lower portionof each main wind speed sensing cup is connected with a wind indicator through a vertical rotating shaft. When the main wind speed sensing cups rotate under the effect of horizontal wind force and meanwhile the wind indicators rotate along with change of the wind direction, generated photoelectric signals corresponding to Gray codes of the wind direction at that moment are output, the main wind speed sensing cups and convertors of the wind indicators transmit data to a microcomputer chip, the data are compiled into set measuring numerical values by the data compiling module, then the measuringnumerical values are stored by the storage module, a plurality of measured data are accumulated by a data accumulating module, and finally, the accurate numerical values are calculated through an error analyzing and calculating module.
