The device has the advantages of being simple in structure, safe, reliable, long in service life, free of moving parts, free of noise, environmentally friendly and the like, continuous and precise control over the temperature of the high-temperature section of the machine barrel can be achieved by controlling the heat dissipating capacity of the cold end of the thermoelectric power generation piece, and the temperature of the low-temperature section of the machine barrel can be precisely controlled by changing the magnitude of current supplied to the semiconductor chilling plate.

The present invention discloses an abnormal data monitoring method and system based on artificial intelligence, which relates to the field of data monitoring technology. The method generates a standardized feature matrix by real-time monitoring and preprocessing data from different sources, effectively reduces data noise and scale differences between features, and analyzes the deviation of each sample relative to the overall distribution, and combines the critical value of the chi-square distribution table to make abnormal judgments on the samples, thereby ensuring the accuracy of abnormal data detection. Then, artificial intelligence technology is used to enhance the abnormal samples, and by introducing distribution constraints, several groups of supplementary abnormal samples are dynamically generated, while ensuring that the generated samples are close to the real distribution, and then by identifying and screening outliers in the abnormal group, the unreasonable samples introduced by noise or deviation in the enhancement process are further reduced, thereby improving the quality of the abnormal group data.
