the data processing and alarming module is also used for: when the instantaneous wind speed values of a plurality of continuous time nodes measured by one anemometer in the strong wind disaster prevention monitoring system are not 0, calculating the standard deviation of the instantaneous wind speed values of all the time nodes of the anemometer in a detection period, judging the discrete characteristic of the anemometer, and when the standard deviation value exceeds a set value, sending out a standard deviation overrun alarm to prompt the anemometer to have a fault and the fault occurrence time;
the data processing and alarming module is also used for: when the standard deviation of the instantaneous wind speed values of all time nodes of one anemometer in one detection period does not exceed a set value; and calculating the turbulence degree of wind in a detection period according to the instantaneous wind speed values of all time nodes of the anemoscope in the detection period, and sending out a turbulence degree overrun alarm to prompt the anemoscope to have a fault and the fault occurrence time when the turbulence degree exceeds a set value.
