Automatic detection method and device for detecting substance composition in viscous material

An automatic detection method for detecting a content of a substance composition in a viscous material, comprising:

• performing a detecting process for the viscous material in a preset detection period in order to obtain a signal detection value corresponding to the viscous material, and generating a signal detection waveform;
• determining a detection state corresponding to the signal detection waveform according to the signal detection waveform, the detection state comprising a normal detection state and an abnormal detection state;
• and
• determining the content of the substance composition in the viscous material based on the signal detection waveform only if the detection state is the normal detection state,
• wherein the substance composition in the viscous material is a composition of at least one impurity substance in the viscous material;
• and
• wherein the automatic detection method further comprises:
• determining a waiting interval between a next detection and a current detection according to the detection state;
• wherein the waiting interval is a first waiting interval if the detection state is determined to be the abnormal detection state, and the waiting interval is a second waiting interval if the detection state is determined to be the normal detection state, and
• wherein the first waiting interval is smaller than the second waiting interval.
