Segmented temperature control adjusting method and system based on Internet of Things

The invention relates to the technical field of data processing, in particular to a segmented temperature control adjusting method and system based on the Internet of Things, and the method comprises the steps: determining the reaction change degree of a current reaction stage according to the change condition of continuously collected reaction kettle data, determining the probability that the reaction kettle data at each acquisition time is a reaction stage change node according to the reaction change degree, and when the probability is greater than a preset probability threshold, determining a plurality of reaction change nodes and a plurality of corresponding reaction stage intervals according to the corresponding reaction kettle data; and calculating, controlling and adjusting parameters according to the temperature change in each reaction stage interval so as to adjust the temperature of the reaction kettle in different reaction stage intervals. A plurality of reaction stage intervals are determined acco
