The invention discloses smart swimming goggles. The smart swimming goggles comprise a goggle body, wherein elastic belts are arranged at two ends of the goggle body and connected through a buckle; a smart system device is mounted on the side surface of the goggle body through magnet adsorption and comprises a processor, a server device, a database and a mobile client, an output end of the processor is connected with the server device through a wireless transceiver and further performs data interaction with the mobile client through an SIM card chip. When a user wears the smart swimming goggles, various sensors on the swimming goggles upload physiological information of the user to the server in real time, the wearing smart swimming goggles also have an interaction function, the server reflects certain set information to the swimming goggles, positioning is realized timely through a GPRS chip, the position is processed by the processor and transmitted timely through a Bluetooth antenna,precise positioning is realized, a message is sent to a mobile terminal through the SIM card chip, and then the user can know the specific physiological status.
