Intelligent flow regulation system and method based on cloud server

The invention relates to an intelligent flow adjusting system and method based on a cloud server. The intelligent flow adjusting system comprises an electric mask and an intelligent mobile terminal operated by a user. The intelligent mobile terminal can obtain predicted environment data corresponding to the positioning information in the cloud server based on the positioning information of the intelligent mobile terminal, the electric mask at least comprises a ventilation accessory and a flow adjustment analysis module, and the system can adjust the flow of the electric mask based on the predicted environment data, the current use situation and/or electrocardiosignals. The change trend of the heart rate data of the user in the current use situation can be predicted in combination with a heart rate change curve of the current user, which is generated according to the historical data and has an association relationship with at least one current use situation; and the flow regulation analysis module can control
