The invention discloses an artificial intelligence epidemic situation big data prevention and control early warning system, which comprises a terminal service platform, a plurality of information acquisition modules connected to the terminal service platform, and switches respectively connected between the plurality of information acquisition modules and the terminal service platform and used forbidirectional communication. According to the invention, face-body temperature-cardiopulmonary multi-mode recognition and intelligent analysis are carried out on a person, so that a traditional singleinfrared temperature measurement mode is broken through, non-contact accurate temperature measurement, cardiopulmonary signal measurement and abnormal alarm are achieved, screening, detection and alarm are mainly conducted on current corona virus disease 2019 patients, especially patients without symptoms, the screening work pressure of key public places can be greatly relieved, and the detectionprobability of suspected persons is increased; and an AI mathematical model algorithm is adopted, so that the system has the data deep mining capability, can perform deep learning by utilizing a neural convolutional network, can predict the epidemic situation development trend, and generates the epidemic situation monitoring and troubleshooting standard in real time.
