Abnormality early warning method and system for electric heating constant-temperature incubator

The invention relates to the technical field of incubator early warning, in particular to an abnormity early warning method and system of an electric heating constant temperature incubator, and the abnormity early warning method comprises the steps: collecting the average temperature value of each moment in a set time period, and constructing a temperature fluctuation sequence according to the difference value of the average temperature values of adjacent moments; constructing a power supply parameter fluctuation sequence according to the power supply parameter difference value of the adjacent moments, and correcting the temperature fluctuation sequence according to the power supply parameter fluctuation sequence to obtain a temperature correction fluctuation sequence; constructing a temperature global uniformity sequence based on the temperature value of the temperature sensor and a target temperature value; constructing a temperature local deviation value sequence according to the deviation of the temperatu
