Stevioside production monitoring data management system

The invention relates to the technical field of abnormal data detection, in particular to a stevioside production monitoring data management system. The system comprises a memory and a processor, and the processor executes a computer program stored in the memory so as to realize the following steps: constructing an ethanol concentration data sequence based on ethanol concentration data at all acquisition moments in a stevioside production process, decomposing the ethanol concentration data sequence to obtain a lower limit value and an upper limit value, further screening out suspected abnormal concentration data; screening characteristic concentration data according to the number of the suspected abnormal concentration data in the neighborhood of each suspected abnormal concentration data; and according to the suspected abnormal concentration data in the neighborhood of each characteristic concentration data in the ethanol concentration data sequence, the characteristic concentration data, the lower limit val
