Method and device for real-time display of hob thermodynamic diagram

The invention provides a hob thermodynamic diagram real-time display method and device. The method comprises the steps that the installation position of a hob on a cutterhead is determined according to a cutterhead diagram; a temperature sensor is used for measuring the temperature value of the hob in real time; establishing a cutterhead temperature image, and marking the measured temperature value of the hob in the cutterhead temperature image according to the installation position of the hob on the cutterhead; deriving adjacent temperature values of the hob according to an interpolation algorithm to obtain temperature values of all pixel points in the cutterhead temperature image; the temperature value is converted into a color value by combining a temperature-to-color value algorithm, and a hob thermodynamic diagram is obtained; according to the obtained color values, the pixel points of the hob thermodynamic diagram are refreshed in sequence, and real-time display of thermodynamic is achieved.
