A windmill rotation detection/management device is provided as being capable of increasing reliability of detection of the number of windmill rotations, or alternatively, subsidizing a controller, which is incapable of processing the number of windmill rotations, so as to effectively utilize windmill rotation count information. This device is applied to a windmill (3) having: a windmill body (31) for receiving a wind and then generating torque; and a generator (32) for generating electric power by means of the torque generated in the windmill body (31). Thus, the device also comprises: a first input line (21) for inputting rotation count information (N1) taken out from the windmill (3) via a rotating speed detector (20); a second input line (22) for inputting rotation count information (N2) taken out from an alternating current output of the generator (32) via a rotating pulse generation circuit (23); and anomaly processing means (24) for executing predetermined anomaly processing in a case where it is determined that there is a rotational difference equal to or greater than a predetermined value in comparison with items of the rotation count information (N1, N2) inputted through both of the input lines (21, 22). |
