The invention discloses an automatic sampling system and a control method of a fermentation tank. In a sampling process, a sampling valve is controlled to be opened, a pipeline valve is controlled to be opened and a bidirectional sampling pump is controlled to be opened by a controller. When a fermentation liquor sample is detected by a liquid sensor, the controller starts timing and delays a certain time to control the sampling valve to be closed, and simultaneously controls a blowing pump and a blowing valve to be opened, and the sample in a delivery pipe is sent to a sampling pool by the sterile air through a sterile air pipe. When the fermentation liquor sample is detected by an electro-conductive liquid sensor in the sampling pool, the controller controls the bidirectional sampling pump to be closed and controls a waste solution valve to be opened, and the redundant fermentation liquor sample in the delivery pipe is discharged to a waste solution bottle through a waste solution pipeline. After the fermentation liquor sample is processed, the controller controls the waste solution valve to be opened and controls the bidirectional sampling pump to reversely rotate, and the fermentation liquor sample in the sampling pool is discharged to the waste solution bottle through the waste solution pipeline. The automatic sampling system is suitable for various fermentation sampling devices, various fermentation tanks can be automatically sampled, and thus an on-line analyzing system can be applied to various fermentation types.
