Zusammenfassung:	The invention relates to an automatic switching method for two sets of wind detecting sensors in draught fan control. The automatic switching method comprises the following steps that 1, a machine set is in a standby state, the power curve of the machine set under the local air density is worked out, and the step 2 is conducted; 2, whether the machine set is switched in or not is judged, and the larger of the two average wind speed values of the two sets of wind detecting sensors serves as the wind speed for judging whether the machine set is switched in or not; 3, the average power within a certain time period is worked out according to the actual output power, and the average wind speed value within the time period in theory is derived reversely through an interpolation method; and 4, the larger of the two average wind speed values serves as the wind speed for judging whether the machine set is switched out or not. According to the automatic switching method for the two sets of wind detecting sensors in dra
