The invention provides an online infrared temperature measuring early warning system of a continuous casting tundish and an early warning method. The temperature measuring early warning system comprises a plurality of temperature measuring elements, a signal processing device and an early warning system. The temperature measuring elements and the signal processing device are connected. The signal processing device receives the input of the temperature measuring elements and converts the input into temperature signals. The early warning system conducts early warning according to the temperature signals obtained through checking and comparing of the temperature transmitted in through the temperature measuring elements and data set in the signal processing device. According to the online infrared temperature measuring early warning system of the continuous casting tundish and the early warning method, the changes of the temperature of a shell of the tundish along with reduction of the thickness of a working liner can be effectively monitored through the temperature measuring early warning system, early warning can be conducted, the use safety of the tundish is improved, and property safety of personnel and equipment is ensured.
