The invention relates to a taxi driver state automatic early-warning platform. The early-warning platform comprises a blood oxygen saturation extraction device, a one-key communication device, a spring driving device and a microcontroller. The blood oxygen saturation extraction device is used for extracting blood oxygen saturation parameters of a driver in a taxi cab. The microcontroller is connected with the blood oxygen saturation extraction device to determine whether to control the spring driving device to drive a spring structure to be ejected out of the one-key communication device according to the extracted blood oxygen saturation parameters. Through the taxi driver state automatic early-warning platform, the situation that the driver drives a taxi in illness can be effectively avoided.
