High temperature probes are installed at the upper, middle and lower positions of the guide grids on both sides of the coke car to monitor the surface temperature of the coke cake, the temperature difference between the upper and lower parts of the coke cake and the horizontal temperature changes, and automatically generate the upper, middle and lower horizontal temperature curves.

By monitoring the coke cake surface temperature again, timely monitor and adjust the standard vertical flue temperature and the temperature difference between the top and bottom of the coke cake, simultaneously detect the horizontal temperature change, and automatically generate the horizontal temperature curve. Through the temperature difference model processing, briefly calculate the coke cake center temperature, and timely alarm when the high and low temperature vertical flue numbers are found.
