Method and device for dynamically adjusting sampling frequency of distributed control system, and electronic equipment

The invention relates to the technical field of electric digital data processing, and particularly discloses a method and device for dynamically adjusting sampling frequency of a distributed control system and electronic equipment. Triggering a sampling window to sample according to the emergency communication message, and calculating an emergency communication frequency through Fourier transform; modifying the sampling frequency according to the calculated emergency communication frequency; judging whether a new emergency communication message exists or not according to the sampling frequency; according to a judgment result, if a new emergency communication message exists, re-triggering the sampling window to sample, and calculating an emergency communication frequency; and if no new emergency communication message exists, the normal sampling frequency is recovered. According to the method, the controller reports the emergency communication, background software analyzes the emergency communication frequency
